Help to Buy — Is It Worth It?

What Help to Buy Actually Was

The Help to Buy Equity Loan scheme was a government intervention designed to solve a specific problem: first-time buyers and home movers could often afford a mortgage's monthly repayments, but couldn't save a large enough deposit to get a competitive mortgage rate, particularly on new-build properties where prices had risen faster than wages in many regions. The scheme's answer was to have the government itself lend part of the deposit — not as a cash loan you repay in instalments, but as an equity stake in the property, repayable on sale or by choice at any point before then.

Mechanically, a buyer needed a minimum 5% cash deposit of their own. The government then lent up to 20% of the purchase price (up to 40% in London, where prices were considerably higher relative to incomes), interest-free for the first five years. The buyer took out a standard repayment mortgage for the remaining balance — commonly somewhere around 75% of the purchase price outside London. The scheme was restricted to new-build homes, bought from registered Help to Buy builders, and was available only in England after Scotland and Wales ran their own separate versions with different rules and closing dates.

The scheme ran in several versions since its 2013 launch, with eligibility, price caps, and regional borrowing limits tightened over time — the final version, running from 2021 to March 2023, restricted eligibility to first-time buyers only (rather than all buyers, as in earlier versions) and introduced regional property price caps that varied considerably by area. It closed entirely to new applications in England in March 2023, meaning the content in this chapter is now primarily relevant to the roughly 350,000-plus households who used the scheme during its decade of operation and are living with an active equity loan today, rather than to someone considering using it for a new purchase.

Why the Government Built It This Way

It's worth understanding the logic behind the scheme's design, because the structure explains almost everything confusing about how it later plays out. The government wanted to help buyers without simply handing out cash grants (which would be a pure cost with no prospect of recovery) and without creating a conventional loan with fixed repayments (which would defeat the purpose of reducing monthly outgoings for buyers who were, by definition, stretched for cash).

The equity loan structure solved both problems at once: the government effectively becomes a part-owner of your home, in proportion to the percentage it lent. Rather than fixed monthly repayments, the "cost" of the loan to the buyer is that the government's percentage stake grows in cash value alongside the property, and shrinks if the property falls in value. This means the government shares in both the upside and downside of the housing market alongside the buyer — which sounds reasonable in the abstract, but produces outcomes that feel very different to a buyer depending on whether their local property market rose sharply or stayed flat during their ownership.

From the government's perspective, this design was attractive because a rising housing market (the historical norm in the UK, with regional variation) meant the equity loan portfolio would likely be repaid at a profit over time, relative to the amount originally lent — a self-funding, or even profit-generating, policy rather than a pure subsidy. From a buyer's perspective, the same mechanism means that the "help" received at the point of purchase has a cost that scales with how much your area's property prices rise over the years you hold the loan — a cost that is genuinely difficult to estimate in advance, because nobody knows future house price movements with any confidence.

It's also worth understanding why the government chose an equity stake specifically tied to new-build properties, rather than extending the same support to any home purchase. New-build developers were, and remain, able to offer more certainty around build timelines and sale prices than the existing-homes market, which made it administratively simpler for the government to run a large-scale scheme through a defined panel of registered housebuilders. This also meant the policy could serve two goals simultaneously — supporting buyer affordability and stimulating housebuilding activity — within a single scheme, rather than requiring two separate interventions, even though it meant buyers who preferred an existing, period, or non-new-build property had no access to the scheme at all, regardless of their income or deposit situation.

How the Equity Loan Actually Works — The Percentage, Not the Pounds

This is the single most important mechanical fact about Help to Buy, and the one most commonly misunderstood by buyers at the point of purchase: the government's loan is denominated in a percentage of your home's value, not in a fixed pound amount. If you bought a £250,000 new-build home with a 20% equity loan, the government lent you £50,000 in cash terms at completion — but what you actually owe them, at any future point, is 20% of whatever the home is worth then, not £50,000.

Run this forward with two different outcomes to see how differently it plays out:

In the rising-market scenario — which was the typical experience for a large share of the scheme's users, particularly those who bought in the earlier years when house price growth was strong — the buyer ends up owing £18,000 more than they originally borrowed, purely because of how much the property appreciated. It's important to be clear that this isn't a penalty or a punitive fee: the buyer also benefits from the same appreciation on their own equity share (the 75–80% they own outright plus their original deposit), so in pure percentage terms they haven't lost out relative to owning the property outright. But in practical, cash terms, many buyers are genuinely surprised when the redemption figure arrives and it's substantially larger than the original loan amount, because the marketing and early conversations around the scheme tend to emphasise the £50,000 figure rather than the percentage mechanism underneath it.

The Interest Period — What Changes After Year Five

For the first five years, the equity loan is genuinely interest-free — the only "cost" during that period is the percentage-of-value mechanic described above, which only becomes relevant when you actually come to repay. From year six onward, however, an annual interest charge begins on the outstanding equity loan, and this is where the scheme's cost can escalate meaningfully if a buyer isn't prepared for it.

The interest rate structure was broadly consistent across most versions of the scheme: in year six, the rate is set at 1.75% of the equity loan amount (not the home's value) and then rises every subsequent year by the previous September's Retail Prices Index (RPI) inflation figure, plus an additional 1% or 2% depending on which version of the scheme applies to a given purchase. Crucially, this interest is calculated on the equity loan's percentage share of the home's current value each year, recalculated annually (typically using the original purchase price until a later point, then an updated valuation) — meaning that in a period of high inflation, the annual interest payment can rise sharply and with little warning, since RPI inflation has, at times in recent years, run into double digits.

This is, structurally, the part of the scheme that most resembles a conventional escalating cost, and it's the reason financial commentators have consistently flagged years six through ten of a Help to Buy loan as the point where many buyers need to actively plan — either to repay the loan (often via remortgaging to a larger mortgage that absorbs the equity loan redemption amount), to sell, or to budget carefully for a genuinely rising annual interest bill that is separate from, and in addition to, their ordinary mortgage repayments.

Repaying the Loan — Full and Partial Redemption

To repay a Help to Buy equity loan — whether because you're selling the home, remortgaging, or simply want to clear the government's stake — you first need an independent, RICS-compliant valuation from a surveyor on the scheme's approved panel. The administrator (a dedicated Help to Buy agent, which varies by region) uses this valuation to calculate the exact redemption figure based on your original percentage share.

You cannot simply repay the original cash amount you borrowed — the redemption calculation is always based on the current valuation, which is precisely why timing matters. If your local market has fallen since purchase, repaying sooner rather than later doesn't help you (and may lock in a loss relative to a future recovery); if your market has risen substantially, delaying repayment means your redemption figure, and the ongoing interest charged on it, keeps climbing.

Partial repayments are allowed, generally in minimum chunks of 10% of the home's current value (so a 20% equity loan can typically be repaid down to 10%, or cleared entirely, but not partially redeemed in smaller increments like 5% or 2%). This flexibility is useful for buyers who come into some savings or a windfall and want to reduce — but not eliminate — the government's stake and the interest charged on it, since interest is only charged on the outstanding percentage still owed.

When selling the property outright, the redemption works automatically through the conveyancing process — your solicitor calculates the government's share from the agreed sale price (which, in a normal arm's-length sale, serves as the valuation) and pays it directly from the sale proceeds before you receive the remainder, in the same way your main mortgage is settled from the proceeds first.

Timing a voluntary redemption (as opposed to one forced by a sale) is a genuinely strategic decision, because you control when the valuation happens, and therefore some influence over which figure the percentage is applied to. Some borrowers deliberately time a voluntary partial or full repayment to coincide with a period when they believe local prices are temporarily soft, rather than waiting for a point when the market has risen further — though this requires a degree of market-timing confidence that's hard to get right consistently, and for most borrowers the more reliable trigger for action is the rising interest cost from year six onward rather than an attempt to predict short-term local price movements.

A Full Worked Example — What the Scheme Actually Cost One Buyer

To make this concrete, take an illustrative buyer who purchased a £280,000 new-build flat in 2017 with a 20% equity loan (£56,000), a 5% deposit (£14,000), and a 75% mortgage (£210,000). They plan to sell or remortgage in year eight, by which point an independent valuation puts the property at £365,000 — a reasonably strong but not extreme rise over the period, broadly in line with regional averages over that timeframe.

The buyer in this example has gained roughly £85,000 in property value overall on a home they could not otherwise have afforded to buy without the scheme — so in net terms, Help to Buy still enabled them to get onto the property ladder years earlier than saving a full deposit independently would have allowed, and they are still considerably better off than if they had continued renting throughout that period. But the "cost" of the equity loan itself — £21,800 more owed than originally borrowed, plus nearly £5,000 in interest payments along the way — is a genuinely large number that most buyers underestimate at the point of purchase, when the scheme is typically framed around the smaller, more reassuring £56,000 figure rather than the percentage mechanism that determines the real, eventual cost.

A Second Worked Example — A Flatter Market

Because so much of the cost of a Help to Buy loan depends on how much the property has appreciated, it's worth contrasting the year-eight example above with a buyer in a region where prices grew much more slowly — a common experience in parts of the country where house price growth lagged the national average for a sustained period.

In the flatter-market scenario, the equity loan's percentage mechanism has cost the buyer comparatively little beyond the ordinary interest charges — the redemption figure is barely above the original loan amount, because the property simply hasn't appreciated much. This illustrates an important, somewhat counterintuitive point: the equity loan mechanism isn't inherently expensive or cheap in isolation — its real cost is almost entirely a function of local house price growth over the specific years you hold it, a variable that was never within any individual buyer's control and was genuinely unknowable at the point of purchase. Two buyers who used identical scheme terms in different towns, or even different years, can end up with very different outcomes purely due to regional property market divergence that has nothing to do with any decision either of them made.

How the Scheme Changed Over Its Decade of Operation

Help to Buy wasn't a single static policy for its entire ten-year run — it evolved through several distinct phases, and which version applies to a given borrower affects some of the fine print, even though the core equity-loan mechanism stayed consistent throughout.

This matters practically because two neighbours who bought similar homes just a few years apart may be on subtly different versions of the scheme — with different regional price caps having applied to their eligibility, though the fundamental interest rate and redemption mechanics described earlier in this chapter remained broadly consistent across all three phases. If you're unsure which version applies to your loan, your original Help to Buy mortgage deed and completion paperwork will specify the exact terms, and your regional Help to Buy agent can confirm the details if the paperwork isn't to hand.

What Happens If Your Property Falls in Value

It's worth being equally clear about the other side of the mechanism, since most public discussion of Help to Buy focuses on rising markets. If your property's value falls below what you paid, the government's redemption amount falls proportionally too — a genuine, if small, consolation in an otherwise difficult situation. The scheme does not insulate the government from a falling market any more than it insulates the buyer.

The real risk in a falling market is not the equity loan itself but negative equity on the overall property — where your main mortgage balance plus the government's equity loan stake together exceed what the property is now worth. This can happen to any highly leveraged buyer, with or without an equity loan, but new-build properties (which Help to Buy requires) have historically shown a tendency to see prices soften somewhat in the first few years after purchase in some markets, partly because new-build prices often carry a premium over comparable existing properties that erodes once the property is no longer "new." Buyers in this position are not in default and face no immediate consequence as long as mortgage payments continue — the issue only becomes practically relevant if you need or want to sell during the period of negative equity, since the sale proceeds would be insufficient to clear both the mortgage and the equity loan in full.

If you find yourself in negative equity with an active equity loan, the most useful first step is usually to simply keep making mortgage payments and wait, rather than forcing a sale — negative equity only becomes a realised loss if you actually sell while the property is worth less than you owe. Most negative equity episodes in UK housing history have eventually been followed by a recovery in nominal prices, often within a handful of years, though there is no guarantee any specific property or region will follow that pattern, and some owners have genuinely been stuck in negative equity for extended periods. Speaking to your mortgage lender early, before any payment difficulty actually arises, is also worthwhile — many lenders have specific support options for borrowers in this position, including temporary payment arrangements, that are considerably easier to access before a payment is actually missed than after.

What's Available Now the Scheme Has Closed

For anyone considering how to get onto the property ladder today without Help to Buy, several alternative routes exist, each with a genuinely different structure and trade-offs rather than being a simple like-for-like replacement:

None of these schemes use the equity-loan structure that defines Help to Buy — the Lifetime ISA bonus is a genuine, non-repayable gift from the government rather than a loan; Shared Ownership and First Homes both tie the subsidy to the specific property rather than creating a separate repayable stake; and the Mortgage Guarantee Scheme works entirely through the mortgage itself rather than a second government loan. Anyone weighing up these alternatives should be clear that Help to Buy's core lesson — that a scheme which looks like it reduces your costs today may have a cost structure that only becomes clear years later — is worth applying to any new scheme too, not just the one that has now closed.

The Policy Debate — Did Help to Buy Make Housing More Expensive?

No discussion of Help to Buy is complete without acknowledging the long-running criticism levelled at the scheme by economists, housing charities, and some parts of the construction industry itself: that by injecting a large pool of government-backed purchasing power specifically into the new-build market, the scheme may have allowed developers to raise new-build prices rather than simply enabling more people to buy at existing prices. This isn't a fringe view — it was raised repeatedly in parliamentary committee reports and by the National Audit Office during the scheme's lifetime.

The logic behind the criticism is straightforward supply-and-demand reasoning: if a large share of buyers in the new-build market suddenly have access to an extra 20% (or 40% in London) of purchasing power they didn't have before, and the supply of new homes doesn't expand quickly enough to absorb that extra demand, developers have room to raise asking prices and still find willing buyers — because the buyer's own required cash outlay hasn't necessarily gone up by the same amount. Some analysis during the scheme's operation found that new-build prices rose faster than comparable existing-home prices in many regions during the years Help to Buy was most heavily used, which is consistent with — though not definitive proof of — this effect.

The counter-argument, made by the government and much of the housebuilding industry at the time, was that the scheme also stimulated genuinely new construction activity that wouldn't otherwise have happened, particularly from smaller developers who relied on guaranteed buyer demand to secure construction finance — meaning at least part of any price effect was offset by more homes being built overall than would have been the case without the scheme.

A Practical Framework for Deciding What to Do With an Existing Loan

For the substantial number of readers of this chapter who have an existing Help to Buy equity loan rather than being a prospective new buyer, the genuinely useful question isn't "was this a good scheme" in the abstract — it's "what should I do with my loan now." Here's a practical sequence for working through that decision.

1. Establish your current position. Get an up-to-date valuation (even an informal estimate from local estate agents is a useful starting point before paying for a formal RICS valuation) and calculate your current redemption figure using your original percentage. Compare this to your original equity loan amount to understand how much the "cost" has grown.
2. Check what year of the loan you're in. If you're still within the first five years, there's no interest cost yet, and there's less urgency — though it's still worth planning ahead, since year six arrives for everyone eventually. If you're already past year five, calculate your current annual interest charge and how it's likely to move with inflation over the next few years.
3. Model the cost of remortgaging to clear the loan versus leaving it in place. A mortgage broker can show you what your monthly payments would look like with a larger mortgage that absorbs the redemption amount, compared to your current mortgage payment plus the separate, rising equity loan interest charge. For many borrowers, especially those well past year five, consolidating into a single larger mortgage at a fixed rate removes the uncertainty of RPI-linked increases and is often, though not always, the lower long-term cost option.
4. Factor in your plans to move. If you expect to sell within the next two or three years anyway, the calculation changes — the equity loan will be settled automatically from the sale proceeds regardless, so taking on a remortgage purely to clear it slightly early may not be worthwhile unless the interest savings clearly outweigh any remortgaging costs (arrangement fees, valuation fees, potential early repayment charges on your existing mortgage deal).
5. Get independent advice before committing. Equity loan redemption decisions involve genuine complexity — valuation timing, interest rate forecasts, and your own mortgage's specific terms all interact. A mortgage broker who has specifically handled Help to Buy redemptions (not all have direct experience with the scheme's specific mechanics) is worth the modest cost of their time before making an irreversible decision.

There is no single universally correct answer here — it depends on your specific numbers, your region's property market trajectory, your risk tolerance for a variable, inflation-linked cost, and how long you intend to stay in the property. What matters is replacing vague anxiety about "that government loan" with an actual, numbers-based comparison of the realistic options available to you.

Who Actually Used the Scheme, and Did It Reach the Right People?

Over its decade of operation, Help to Buy supported several hundred thousand purchases, making it one of the largest housing interventions in recent UK policy history by sheer volume. Government data published across the scheme's lifetime consistently showed the typical user was in their late twenties to mid-thirties, buying a first home, with a household income in a range that put them above the threshold for most means-tested support but still meaningfully below what was needed to save a conventional deposit quickly in a high-price region — in other words, broadly the group the scheme was designed for.

That said, the scheme attracted genuine scrutiny over whether its benefits were evenly distributed. Analysis from housing charities and parliamentary committees during the scheme's operation repeatedly noted that a disproportionate share of buyers using the higher 40% London limit were on incomes well above the national median — not because wealthier buyers were gaming the system, but because the properties eligible for the scheme in London were priced high enough that only buyers with above-average household incomes could afford the remaining mortgage and deposit, even with the government's equity loan reducing the gap. This is a structural feature of means-testing by price cap rather than by income: a price-based eligibility rule can end up favouring higher earners in expensive regions purely because of where the eligible properties happen to sit in the local market.

None of this changes the mechanics covered elsewhere in this chapter for any individual borrower, but it's useful context for understanding why the scheme attracted sustained political debate throughout its existence, and why its eventual closure in 2023 was broadly expected rather than a surprise policy U-turn — by the scheme's final years, government messaging had already shifted toward presenting the Mortgage Guarantee Scheme and the Lifetime ISA as the preferred long-term tools for first-time buyer support, with Help to Buy positioned as a legacy scheme being wound down deliberately.

The Broader Lesson for Anyone Using Government Homebuying Support

Stepping back from Help to Buy specifically, the scheme is a genuinely useful case study in reading the fine print of any government support that comes with strings attached, because its core lesson generalises well beyond housing. Support that reduces an upfront cost (a deposit, in this case) without eliminating the underlying financial exposure (ownership of a percentage stake that moves with the market) can look, in year one, exactly like a straightforward subsidy — and only reveal its true cost structure years later, once interest starts accruing or a sale forces a redemption calculation.

The practical habit worth taking from this, applicable to any financial product with a multi-year structure — mortgages, car finance, "buy now pay later" products, or future government schemes — is to ask explicitly, before signing anything: what happens in year five, year ten, and at exit, not just what the headline benefit looks like on day one. Help to Buy's five-year interest-free period made the scheme attractive and genuinely helpful to hundreds of thousands of buyers at the point of purchase; the CPI/RPI-linked interest escalation and percentage-of-value redemption are what determine whether it was, in hindsight, a good deal for any individual buyer — and that verdict depends entirely on factors (future house price movements, future inflation) that were essentially unknowable at the point the mortgage was signed.

It's also worth stating plainly what this chapter is not arguing: Help to Buy was not a bad scheme for everyone who used it, and for a large share of buyers — particularly those who bought in the scheme's earlier years and have since seen strong, broad-based house price growth — it was a genuinely effective route onto the property ladder that they would not otherwise have had, even accounting for the rising redemption figure and interest charges covered in detail above. The point of walking through the mechanics this thoroughly isn't to suggest buyers made a mistake; it's that the scheme's true cost was genuinely difficult to estimate at the point of signing, because it depended on variables — future regional house price growth, future inflation — that nobody could know in advance. Understanding the mechanism after the fact at least allows existing borrowers to make an informed decision about what to do next, rather than treating the equity loan as a fixed, unchanging fact of their mortgage that doesn't require active management.
