The Arithmetic of a Smaller Deposit
Britain has run this experiment before. In 2013 Help to Buy let buyers put down a 5% deposit on a newly built home worth up to £600,000, with up to 20% of the cost funded by a shared equity loan that was interest-free for the first five years. A deposit is a hurdle; a loan is a schedule. A policy can lower the first without touching the second. Thirteen years on, the shape has returned with a new name, a new prime minister and a smaller deposit, and the same question sits underneath it: what has actually been made cheaper, and for how long.
Your First Home applies to England only, and only to people buying a new-build flat or house as their first home. [1]. The minimum deposit is 2.5% of the purchase price. A government-backed equity loan — a loan that counts as part-ownership of the home and is repaid later, not given — covers 20% of that price. The buyer then takes a standard mortgage — an ordinary home loan from a bank, repaid monthly over decades — for the remaining 77.5% of the property’s value. Those three figures — 2.5, 20, 77.5 — sum to 100, and the way they sum is the policy. On the day of completion the buyer’s own stake is the deposit itself. A fifth of the home is financed by the state through a loan rather than a grant, which means it is money to be repaid and not money given. The rest is ordinary mortgage debt, secured in the usual way against the property. More detail is promised at the Budget on 28 October, which is also when the scheme is due to be formally confirmed.
The argument for the scheme is about the month, not the decade, and the government’s own comparison is with the standard 95% mortgage many first-time buyers rely on. [1]. Because the equity loan carries no interest at the start, the government says participants “could save hundreds of pounds per month” compared with the standard 95% mortgage that many first-time buyers rely on. [1] The arithmetic of the deposit is just as concrete. On an average first-time buyer home of around £230,000, a 2.5% deposit comes to £5,750; at 5% the same buyer would need £11,500. That is roughly half the cash upfront for the same property, and it is worth being precise about what has changed. Not the price. Not the total amount borrowed, which rises. What has changed is the split between what the buyer must find from savings and what the buyer must service afterwards. A 77.5% mortgage plus a 20% equity loan means 97.5% of the price is still financed by borrowing. The relief may be genuine in the early years; its size in the later ones depends on terms nobody has published.
The scheme is aimed at a specific person: someone with a regular income who has been unable to save a large deposit, or who cannot call on what is usually called the “bank of mum and dad”. That distinction matters, because a deposit constraint and an affordability constraint are not the same problem, and a policy that solves the first does not automatically solve the second. Two design questions remain open. Both are the kind of detail that could shape who benefits in practice: a price cap might determine whether the scheme reaches the cheaper end of the new-build market or the middle of it, and an age limit might determine whether a 45-year-old renter with a stable job is inside or outside.
What the Predecessor Actually Delivered
Britain has run this experiment before, and the record is public. The scheme ran in two forms. The first was active until 2021; a second iteration, which ran until 2023, restricted access to first-time buyers and applied regional price caps to the properties that could be bought. [1] The new scheme begins roughly where that second version stopped: first-time buyers only, new builds only. The difference is that ministers have not yet confirmed whether there is an age restriction on the scheme, or a cap on the value of the property. [1].
Your First Home combines a 2.5% deposit with an equity loan of 20% that is interest-free for an initial period whose length has not been stated. [1] The two features that defined the predecessor — the equity loan and the restriction to newly built homes — are both present in the successor. The continuity is in the design. The discontinuity, so far, is in the disclosure.
The industry response arrived quickly and was positive. The Home Builders Federation said it had “long called for action to improve access to home ownership” and that a “well-designed scheme has the potential to make a real difference to households who are struggling to get onto the housing ladder”. [1]. That judgement comes from the sector with the most direct commercial interest in the outcome, since every buyer who can use this scheme must buy a new build. The Prime Minister’s own justification points the same way. Andy Burnham said he believes the scheme will give builders the “confidence to deliver the high-quality new homes the country needs”. [1]. That is a supply argument attached to a demand instrument, and it is where the balance of the case sits. The benefit depends on homes being built that would not otherwise have been built at that price; the published material does not yet say how many, or by when, or what happens if the answer is few.
Who pays is partly specified. Funding for the scheme is expected to come from reprioritising existing budgets rather than from new money, and housing developers will pay towards the running costs. [1]. A government-backed equity loan also means the public balance sheet holds a share of the price for as long as the loan runs, which makes it a contingent asset and a contingent liability at the same time. If the value of the property rises, the state’s 20% is worth more; if it falls, the state’s claim is worth less, and the material published so far does not describe how that is handled. What is clear is the direction of the cash. Public support goes in at the point of purchase to reduce the deposit. Private money comes back in running costs from the developers whose stock the scheme can be used to buy. Between those two flows sits the buyer, holding 2.5% of the equity and 100% of the mortgage obligation.
Two Sides and an Unset Price Cap
The political case for the scheme is made in the language of exhaustion. Andy Burnham said: “Too many young people are struggling with the cost of housing, with many giving up hope of ever having a home to call their own.” [1] He added: “So we will step in to help more first-time buyers on to the housing ladder.” The target group is defined by what it lacks rather than by what it earns: a regular income is assumed, a large deposit is not, and parental support is absent. That framing is politically potent because it divides the housing market into two populations — those whose parents can supply equity and those whose cannot — and offers help to the second. The timing follows the same logic. The announcement came as the prime minister prepared for his first Labour conference as leader, with a separate package on empty homes released the same weekend.
The Conservative objection is not to the goal but to the mechanism. The Conservatives warned the policy would leave first-time buyers taking on more debt and risks “pushing up the price of new homes”. [1] The shadow minister for state housing and planning, Gareth Bacon, accused Rayner of “desperately reaching for any lever she can find” to hit “Labour’s 1.5 million homes target”. [1]“. The first claim is arithmetic anyone can test, because a buyer who puts down 2.5% instead of 5% borrows more, across two instruments rather than one. The second is a claim about incidence — about who ends up holding the subsidy when the supply of homes does not move quickly — and it is the standard objection to any demand-side help in a market where the number of properties for sale is slow to change. Both claims can be true at once, and neither is settled by an announcement.
The empty homes package sits beside the buyer scheme and works on a different part of the problem. Labour said the plans would make it simpler for councils to take over empty properties and bring some of the more than 300,000 empty dwellings into use for essential housing. [1]. That figure is the most concrete supply number in the whole set of announcements, and it is a stock rather than a flow: houses that already exist and are not occupied. Bacon’s answer to that part was that Rayner was reaching for whatever lever was available to meet the 1.5 million homes target. The two measures therefore touch opposite ends of the same ledger. One adds purchasing power to buyers of new homes. The other tries to bring existing homes into use, and a home brought back into use is not a new build, so it cannot be bought through Your First Home. The scheme’s supply side and its demand side are not connected by design; they are connected only by a shared press cycle.
The only measured verdict on this model comes from the scheme it most resembles. An evaluation of Help to Buy found more than 387,000 properties were purchased through it, of which 328,000 were by first-time buyers, and concluded that the programme was “effective in supporting people into home ownership in some areas, but did not remove affordability barriers for first-time buyers in areas that were already relatively expensive”. [1] That sentence contains both halves of the case, and neither cancels the other. The scheme worked where homes were cheap enough for a smaller deposit to be the binding constraint, and it did not work where the price was the problem rather than the deposit. Your First Home halves the deposit from 5% to 2.5% and leaves the price where the market puts it. On an average first-time buyer home of around £225,000 that is a difference of a little over £5,600 in cash at completion, a fifth of the price carried on the public balance sheet, and a 77.5% mortgage that still has to be paid every month for its full term. [1]. The deposit is smaller. The debt is not.
