The Ultimate UK First-Time Buyer Mortgage Guide 2026

What is a first-time buyer mortgage?

A first-time buyer mortgage is any home loan taken out by someone who has never owned residential property before. In practical terms, every standard mortgage product on the market is available to first-time buyers, but many lenders also offer exclusive deals specifically aimed at this group — including lower fees, cashback incentives, and the ability to borrow with a smaller deposit.

The UK government also provides several incentives to help first-time buyers get on the property ladder, from stamp duty relief to savings bonuses and shared ownership schemes. Understanding what is available to you is the first step toward owning your own home. For a broader overview of how mortgages work, see our complete UK mortgage guide.

How much deposit do you need?

The deposit is almost always the biggest hurdle for first-time buyers. Here is a realistic breakdown of what you should aim for:

• 5% deposit — the minimum most mainstream lenders require. On a £250,000 property, that is £12,500. You will have a much wider choice of lenders and products at this level compared to a few years ago.
• 10% deposit — this is the threshold where interest rates start to drop noticeably. Expect to save between 0.3% and 0.5% off your rate compared to a 5% deposit deal, which over 25 years adds up to thousands of pounds.
• 15-20% deposit — the sweet spot for the very best rates. Lenders consider you lower risk, so they reward you with their most competitive products.

If saving a deposit feels impossible, look into the Lifetime ISA (the government tops up your savings by 25%), family-assist mortgages (where a parent places savings with the lender as security), and shared ownership (where you buy a share of the property and pay rent on the rest).

Government schemes for first-time buyers

Several government-backed programmes exist to help first-time buyers in 2026:

Shared Ownership

You buy a share of a property (between 25% and 75%) and pay rent on the remaining share to a housing association. Over time you can buy additional shares — a process called "staircasing" — until you own the property outright. This scheme dramatically reduces the deposit and mortgage amount you need to begin with.

First Homes

A scheme offering newly built homes to local first-time buyers and key workers at a discount of at least 30% compared to the market price. The discount is locked into the property in perpetuity, meaning future buyers also benefit. Eligibility depends on your household income and the local authority area.

Lifetime ISA

If you are between 18 and 39, you can open a Lifetime ISA and save up to £4,000 per year. The government adds a 25% bonus (up to £1,000 per year) to your savings. You can use the funds toward a first home worth up to £450,000. This is one of the most generous savings incentives available and should be a cornerstone of your deposit strategy.

Right to Buy

If you are a council or housing association tenant, you may be eligible for the Right to Buy or Right to Acquire scheme, which lets you purchase your home at a substantial discount. The discount depends on how long you have been a tenant and the type of property.

Stamp duty relief for first-time buyers

First-time buyers benefit from reduced stamp duty rates in England and Northern Ireland. You pay no stamp duty on the first £300,000 of your property purchase for homes up to £500,000. On the portion between £300,001 and £500,000 you pay 5%. If the property costs more than £500,000, the relief does not apply and you pay standard rates on the entire amount.

This relief can save you thousands of pounds. On a £400,000 purchase, for example, you would pay £5,000 in stamp duty rather than the standard £10,000 — a saving of £5,000. We recommend using our stamp duty calculator to see exactly what you would pay.

How much can you borrow?

Most lenders will offer between 4 and 4.5 times your annual gross income, though some will stretch to 5 or even 5.5 times for high earners or certain professionals (such as doctors, solicitors, and accountants). If you are buying with a partner, your combined incomes are used.

Beyond the income multiple, lenders also carry out a detailed affordability assessment. They look at your regular outgoings, existing debts (credit cards, loans, car finance, student loans), your spending patterns, and whether you could still afford payments if interest rates rose. This is called "stress testing."

Our affordability calculator gives you a quick estimate, but for a definitive answer on what you can borrow, speak to one of our advisers. We know which lenders are most generous in their calculations and can often find options that high street banks cannot.

The mortgage application process step by step

Buying your first home can feel daunting, but breaking it down into stages makes it much more manageable. See our how it works page for a visual overview of the process.

1. Get an Agreement in Principle (AIP) — this is a conditional offer from a lender confirming how much they are willing to lend you, based on a soft credit check and basic financial information. Most estate agents expect you to have one before making an offer. We can arrange an AIP in as little as 24 hours.
2. Find your property — with your budget confirmed, start viewing properties and make an offer when you find the right one.
3. Submit a full mortgage application — once your offer is accepted, we submit a detailed application to the lender with full documentation (payslips, bank statements, ID, etc.).
4. Valuation — the lender sends a surveyor to value the property and confirm it is suitable security for the loan.
5. Mortgage offer — if the lender is satisfied, they issue a formal mortgage offer. This is the green light.
6. Conveyancing — your solicitor carries out legal checks (searches, title review, contract review) and liaises with the seller's solicitor.
7. Exchange of contracts — both parties are now legally committed. You pay your deposit to the solicitor.
8. Completion — the mortgage funds are released, the balance is paid, and you collect the keys to your new home.

What fees should you budget for?

Beyond the deposit, there are several costs first-time buyers need to be prepared for:

• Solicitor or conveyancer fees — typically £1,000 to £2,000 including searches and disbursements
• Survey or valuation — a basic valuation may be included free by the lender; a homebuyer's report or full building survey ranges from £300 to £1,500 depending on the property
• Mortgage arrangement fee — some of the best-rate products charge a fee of £500 to £2,000, which can often be added to the mortgage balance
• Broker fee — we will always confirm our fee upfront before any work begins
• Moving costs — removal vans, cleaning, and setting up utilities typically cost £500 to £1,500
• Furniture and essentials — budget at least £2,000 to £5,000 for the basics if the property is unfurnished

Tips to improve your chances of mortgage approval

• Check your credit report — register on the electoral roll, correct any errors, and ensure all addresses are up to date
• Reduce existing debt — pay down credit cards and avoid taking on new credit in the months before you apply
• Save consistently — lenders like to see a regular savings pattern in your bank statements
• Avoid overdraft use — staying out of your overdraft for 3-6 months before applying shows financial discipline
• Keep your spending sensible — lenders review 3 months of bank statements and excessive gambling, luxury spending, or unexplained large transactions can raise flags
• Speak to a broker early — we can review your situation months before you plan to buy and give you a tailored action plan to maximise your borrowing power. Get in touch for a free consultation
