Nearly four out of five UK adults say saving a deposit is one of the biggest barriers to buying a home, according to recent research. That figure has stayed stubbornly high for years, and it’s the first thing people mention when I ask why they haven’t started looking yet. I’ve been covering the UK housing market long enough to see the same pattern repeat: people assume they need a 20% deposit or a perfect credit score before they can even speak to a lender. That assumption keeps a lot of potential buyers stuck in rented homes longer than necessary.
The truth is that getting prequalified for a home in the UK is more straightforward than most people think — provided you know which schemes exist and which ones you actually qualify for. Over the years, I’ve watched buyers waste months chasing the wrong option because they didn’t understand the difference between a Lifetime ISA and a Shared Ownership scheme. That’s what this guide is for. Here’s what you actually need to know.
What prequalification actually means for a UK home buyer
Prequalification isn’t a mortgage offer. It’s a quick check a lender does to see roughly how much they might lend you based on basic information — your income, outgoings, and deposit size. It doesn’t involve a hard credit check, and it doesn’t guarantee you’ll get the loan. What it does is give you a realistic price range before you start viewing properties. That matters because the average first-time buyer is now looking at properties costing £244,100, and knowing your ceiling stops you falling in love with something you can’t afford.
If I were starting today, I’d get prequalified with at least two or three different lenders before I even opened Rightmove. The numbers can vary by tens of thousands of pounds depending on the lender’s criteria. It’s also the moment to check which government schemes you’re eligible for, because that can change the deposit you need and the monthly payments you’ll face. A good first step is to read up on smart ways to finance your purchase so you know what’s available before you speak to a mortgage adviser.
Why getting prequalified early saves you money and stress
The biggest mistake I see is people waiting until they’ve found a property to start thinking about finance. By then, you’re under time pressure, you might accept a worse rate, or you discover you’re not eligible for the scheme you were counting on. Getting prequalified early flips that around. You know your budget, you know which schemes apply, and you can move fast when the right property comes up.
Consider the numbers. Under the Mortgage Guarantee Scheme, you can buy with a 5% deposit. On an average-priced home of £244,100, that’s a deposit of just £12,205 — compared to £48,820 if you needed 20%. That’s a difference of over £36,000. The scheme, made permanent in July 2025 and often called “Freedom to Buy,” has already helped complete more than 53,000 mortgages since it launched. It’s not a niche option; it’s a mainstream route that thousands of buyers use every year.
But there’s a catch that doesn’t get talked about enough. The scheme only guarantees mortgages between 91% and 95% loan-to-value. That means if you have a 6% or 7% deposit, you might not benefit at all — you’d fall outside the guaranteed range. That’s the kind of detail that matters when you’re planning. If you’re in that middle ground, a Lifetime ISA might be a better bet because the 25% bonus works regardless of your deposit size. You can save up to £4,000 a year and the government adds up to £1,000 annually, which can be used towards your deposit on a home worth up to £450,000.
Where people go wrong when trying to get prequalified
Assuming you need a 20% deposit
This is the most persistent myth I encounter. The research shows 79% of UK adults say saving a deposit is a major challenge, and that’s partly because people think they need far more than they actually do. The Mortgage Guarantee Scheme, Shared Ownership, and First Homes all work with deposits as low as 5%. If you’re a first-time buyer, you almost certainly qualify for at least one of these. The key is to check eligibility early rather than assuming you’re locked out.
Ignoring the Stamp Duty thresholds
The temporary Stamp Duty relief expired in April 2025. As of 2026, first-time buyers pay no Stamp Duty on properties up to £300,000, then 5% on the portion between £300,001 and £500,000. Above £500,000, no relief applies at all. That changes the maths significantly. A property at £310,000 costs you £500 in Stamp Duty. A property at £510,000 costs you thousands more because the relief disappears entirely. I’ve seen buyers stretch their budget to £510,000 only to realise they’ve added thousands in tax they hadn’t planned for. If you’re close to that threshold, it’s worth understanding the hidden home buying costs before you commit.
Overlooking the Own New Rate Reducer
This is a newer option that many buyers haven’t heard of. The Own New Rate Reducer scheme uses the housebuilder’s incentive budget to lower your mortgage rate — in some cases to under 1%. For example, if a housebuilder offers a 5% discount on a new home, Rate Reducer takes that sum and offsets it against the mortgage interest. On a £350,000 mortgage at 60% LTV over 40 years, the rate could drop from 4.79% to 0.99%, saving £756 per month. Six lenders, including Halifax and Virgin Money, and over 200 housebuilders currently participate. It’s only available on new builds, but if you’re looking at new homes, it’s worth asking the developer whether they work with the scheme.
Not checking Shared Ownership lease terms
Shared Ownership lets you buy a share of 10–75% and pay rent on the rest, with deposits as low as 5% of your share’s value. That sounds great, and it can be. But the properties are almost always leasehold, and you’ll likely pay a monthly service charge plus contributions to major works. Those costs can rise unexpectedly. Before you commit, ask for the last three years of service charge statements and check whether there are any planned major works. A property lawyer can review the lease for you — it’s money well spent.

How to get prequalified: a step-by-step guide
Check your eligibility for government schemes first
Before you speak to any lender, work out which schemes you qualify for. The Mortgage Guarantee Scheme is open to first-time buyers and home movers, but only for mortgages between 91% and 95% LTV. The Lifetime ISA requires you to be a first-time buyer buying a home under £450,000. Shared Ownership has income caps that vary by location. First Homes is for local first-time buyers and comes with a minimum 30% discount. Write down which ones apply to you — that list will determine which lenders and products are worth your time.
Get your documents in order
Lenders will ask for proof of income, bank statements, ID, and details of your outgoings. Having these ready before you apply for prequalification speeds everything up. You’ll need three months of payslips if you’re employed, or two years of accounts if you’re self-employed. A video doorbell might seem unrelated, but if you’re viewing properties while working from home, it helps you stay on top of deliveries and appointments without missing a beat. It’s a small organisational win that keeps the process moving.
Use a mortgage broker or compare lenders directly
A good broker can check your eligibility across multiple lenders and schemes in one go. They’ll also know which lenders are most flexible with the schemes you qualify for. If you prefer to go direct, use a comparison site that filters by scheme type. Either way, get prequalified with at least two lenders. The rates and maximum loan amounts can differ significantly, and having a backup option is useful if your first choice falls through.
Consider the New Build Boost if you’re buying from Persimmon or Charles Church
This scheme combines a traditional mortgage with an interest-free equity loan of 15%, giving you access to 80% LTV mortgages even with a smaller deposit. You need a 5–15% deposit, and the loan is interest-free for the full mortgage term. The application process is simplified — you apply for the mortgage and equity loan in one go. The catch is that the loan’s value adjusts in line with the market after five years, though it’s capped at twice the original amount. It’s not available in Scotland or Wales, so check location eligibility first.
Factor in the Stamp Duty thresholds for 2026
With the temporary relief expired, the thresholds are now: £0 Stamp Duty up to £300,000 for first-time buyers, 5% on the portion from £300,001 to £500,000, and no relief above £500,000. If you’re looking at properties around £300,000, a small increase in budget could cost you thousands in tax. Factor that into your prequalification calculations so you’re not caught out. A property lawyer can help you understand how the thresholds apply to your specific situation and check the legal side of your purchase.
