Nearly four out of five UK adults say saving a deposit is one of their biggest housing worries. That figure comes from research that tracks what people actually find hardest about buying a home, and it matches what I hear again and again from readers. The deposit hurdle isn’t just about the total amount — it’s about knowing which schemes exist to make that amount smaller, and which ones you actually qualify for.
I’ve been writing about UK home buying for years, and the single most common mistake I see is people assuming they need a 10% or 20% deposit. That assumption keeps a lot of perfectly capable buyers on the sidelines. The truth is that several government-backed schemes let you buy with as little as 5% down, and some even give you free money toward that deposit. The trick is knowing which scheme fits your situation and how to apply before you start house hunting. Here’s what you actually need to know.
How down payment assistance actually works in the UK
The phrase “down payment assistance” sounds American, but the UK has its own set of schemes that do the same thing — reduce the cash you need upfront. The most important thing to understand is that these aren’t loans you have to pay back. They’re either government guarantees that let lenders offer higher loan-to-value mortgages, direct discounts on the purchase price, or savings bonuses that boost your deposit fund.
The Mortgage Guarantee Scheme, made permanent in July 2025 and sometimes called the Freedom to Buy scheme, is the closest thing to a straightforward deposit-reduction tool. It covers mortgages between 91% and 95% LTV, meaning you can borrow up to 95% of the property’s value. The government guarantees part of the lender’s losses if you default, which encourages banks to keep offering these high-LTV loans. More than 53,000 mortgages have been completed through this scheme since it first launched in 2021. If I were starting from scratch with a small deposit, this is the first scheme I’d check — it’s open to first-time buyers and home movers alike, and it doesn’t limit you to new-build properties.
Why the right scheme can save you thousands
The difference between using a scheme and going it alone isn’t small. Take the Lifetime ISA as an example. You can save up to £4,000 a year, and the government adds a 25% bonus — that’s up to £1,000 in free money annually. Over three years, that’s £3,000 you didn’t have to earn or save. For someone aiming for a £15,000 deposit on a £300,000 home, that bonus could cover a fifth of the target.
But the schemes aren’t one-size-fits-all. Shared Ownership, for instance, lets you buy a share of a property — typically between 10% and 75% — and pay rent on the rest. Your deposit is 5% of the share you’re buying, not the full property value. If you buy a 25% share of a £200,000 home, your deposit is 5% of £50,000, which is just £2,500. That’s a world away from the £10,000 you’d need for a 5% deposit on the full price. The trade-off is that you’ll have monthly rent and service charges on top of your mortgage, and the property is usually leasehold. I’ve seen buyers get caught out by those ongoing costs, so it’s worth running the full monthly numbers before you commit.
Regional differences matter too. The First Homes Scheme offers a minimum 30% discount on new-build homes, but it’s designed to favour local buyers and is only available in certain areas. If you live in a high-value market like London or the South East, the £450,000 property cap on the Lifetime ISA might limit your options. In cheaper regions, that cap is rarely an issue. The key is matching the scheme to your local market, not just your savings balance.
Where first-time buyers trip up
The most common errors I see aren’t about failing to save enough — they’re about misunderstanding the rules and missing deadlines. Here are the ones that cost people the most.
Assuming the old Help to Buy Equity Loan is still available
The Help to Buy Equity Loan scheme closed to new applicants on 31st October 2022 and ended entirely on 31st March 2023. I still get emails from people asking about it. That scheme let you buy a new-build home with a 5% deposit and borrow up to 20% of the property’s value from the government (40% in London). It’s gone. The replacement is the Mortgage Guarantee Scheme, which works differently — it’s a government guarantee to the lender, not a loan to you. You still need a 5% deposit, but you don’t get the extra government loan on top. If you’re searching online and see old articles about Help to Buy, check the date before you get your hopes up.
Ignoring the stamp duty threshold change
As of April 2025, the temporary stamp duty relief for first-time buyers expired. The threshold reverted to £300,000. That means you pay no stamp duty on the first £300,000, then 5% on the portion between £300,001 and £500,000. Above £500,000, no first-time buyer relief applies at all. If you’re buying at £310,000, you’ll owe 5% on the £10,000 above the threshold — that’s £500 you might not have budgeted for. A property lawyer can help you calculate exactly what you’ll owe and whether any local exemptions apply, which is worth doing before you make an offer.
Overlooking the Lifetime ISA withdrawal penalty
The 25% government bonus on a Lifetime ISA sounds like free money, and it is — as long as you use it for your first home or retirement. If you withdraw for any other reason, you lose the bonus plus a penalty that effectively takes back some of your own contributions. The property must also be worth £450,000 or less. If you’re house hunting in an area where prices regularly exceed that, the LISA could lock you out of the market you’re actually shopping in. I’d only open a LISA if I was confident I’d buy within that price cap within a few years.
Forgetting the additional costs beyond the deposit
The deposit gets all the attention, but the other costs add up fast. Conveyancing fees run between £1,000 and £1,500. Surveys range from £400 for a basic Homebuyer’s Report to £1,500 for a full Building Survey on an older property. Then there are mortgage arrangement fees, moving costs, and initial furnishing. If you’re putting down a 5% deposit on a £250,000 home, that’s £12,500. The additional costs could easily add another £3,000 to £4,000. A financial advisor can help you map out the full cash requirement so you’re not caught short on completion day.

Picking the right scheme comes down to three things: your deposit size, the property price in your area, and whether you’re set on a new-build or open to anything. Here’s how to work through each option.
Start with the Mortgage Guarantee Scheme if you have a 5% deposit
This is the most flexible option because it works on any property type up to £600,000 (the standard mortgage cap for most lenders), and it’s open to first-time buyers and home movers alike. You apply through a normal mortgage lender who participates in the scheme. The government guarantee means the lender can offer you a 95% LTV mortgage without taking on excessive risk. The catch is that affordability checks are still strict — you’ll need to prove you can handle the monthly repayments, which will be higher than on a loan with a bigger deposit. If your income is stable and your credit history is clean, this is the simplest path. If you’re unsure about your eligibility, a financial advisor can run the numbers with you before you apply.
Use a Lifetime ISA to supercharge your savings
If you’re still building your deposit and have at least a year before you plan to buy, open a Lifetime ISA now. You can deposit up to £4,000 per tax year, and the government adds 25% — that’s an instant return you can’t get from a standard savings account. The money must go toward your first home worth £450,000 or less, or you’ll face a withdrawal penalty. The process is straightforward: open the account with a provider like a bank or investment platform, set up regular deposits, and the bonus is added monthly or annually depending on the provider. If you’re saving over multiple years, the compounding effect of the bonus on top of interest can make a real difference. A Lifetime ISA guide book can walk you through the provider options and the fine print on penalties.
Consider Shared Ownership if you’re in a high-price area
Shared Ownership is designed for people who can afford a mortgage but not the full deposit on a home in their area. You buy a share — typically between 10% and 75% — and pay rent on the rest. Your deposit is 5% of the share price, not the full property value. Over time, you can buy more shares through “staircasing” until you own the whole property. The downsides are that the property is usually leasehold, you’ll pay monthly service charges, and resale can be more complicated than with a standard freehold home. If you’re in London or another expensive city, this might be the only realistic path to ownership. Check with your local housing association or the government’s Own Your Home website for available properties in your area.
Look into First Homes if you’re buying new-build locally
The First Homes Scheme offers a minimum 30% discount on new-build homes for local first-time buyers. That discount is applied to the market value, so you get instant equity. Eligibility is tied to local income caps and residency requirements — the scheme is meant to keep communities affordable for people who already live there. Availability is limited and region-specific, so not every town or city has First Homes on offer. If you’re flexible on location and willing to buy new-build, this can be the most financially powerful option because the discount is effectively free equity. Check with your local council’s planning department to see if any First Homes developments are in the pipeline.
