First-Time Buyer Guide UK 2026: Stamp Duty, Deposits and Mortgages

Buying your first home is one of the most exciting financial decisions you'll make, but it can feel overwhelming with all the costs, paperwork, and jargon to navigate. The good news? The UK government offers substantial support for first-time buyers, particularly through stamp duty relief that can save you thousands of pounds. Whether you're saving for a deposit, understanding mortgage options, or calculating your stamp duty bill, this guide will walk you through everything you need to know in 2026.

Understanding Stamp Duty for First-Time Buyers

One of the biggest advantages of being a first-time buyer is stamp duty relief. If you're purchasing your first home in England or Northern Ireland, you'll pay no stamp duty at all on properties up to £300,000. This is a significant saving compared to repeat buyers, who start paying stamp duty at £125,000.

Current First-Time Buyer Stamp Duty Rates (2026)

The stamp duty thresholds changed on 1 April 2025, so it's important to know the current rates:

• £0 to £300,000: 0% stamp duty
• £300,001 to £500,000: 5% stamp duty (only on the amount above £300,000)
• Over £500,000: Standard stamp duty rates apply

Remember, you only pay the percentage on the portion of the price within each band. This means if you're buying a property for £325,000, you'd pay 0% on the first £300,000 and 5% on the remaining £25,000, which equals £1,250 in total stamp duty.

Stamp Duty Examples for Common Property Prices

Here's what you'd actually pay as a first-time buyer at different price points:

• £300,000 property: £0 stamp duty
• £350,000 property: £2,500 stamp duty
• £400,000 property: £5,000 stamp duty
• £500,000 property: £10,000 stamp duty

To put this in perspective, if you were buying the same £300,000 property as a repeat buyer (someone who's owned property before), you'd pay £5,000 in stamp duty. That's a significant saving for first-time buyers.

Who Qualifies for First-Time Buyer Relief?

To claim first-time buyer stamp duty relief, you must meet these criteria:

• You're buying your first home
• Anyone you're buying with is also a first-time buyer
• It's not an investment property or buy-to-let
• The property is valued at £500,000 or less

If you're buying a buy-to-let as a first-time buyer, you won't qualify for this relief and will pay higher stamp duty rates.

Saving for Your Deposit

Before you even get to stamp duty, you'll need to save for a deposit. Most mortgage lenders require a deposit of between 5% and 20% of the property price, though some specialist lenders may accept smaller deposits.

How Much Deposit Do You Need?

The amount you can borrow depends on your income and the lender's criteria, but here's a rough guide:

• 5-10% deposit: Higher interest rates, you'll pay mortgage insurance
• 10-15% deposit: More competitive rates, reduced mortgage insurance costs
• 20% deposit: Best mortgage rates available, no mortgage insurance needed

If you're struggling to save a large deposit, look into government schemes like Help to Buy (if you're eligible) or consider whether family members can help with a gift towards your deposit.

First-Time Buyer ISAs and Savings Accounts

You can save up to £4,000 per tax year in a Lifetime ISA (if you're aged 18-39), and the government will add a 25% bonus on top of your savings, up to £1,000 per year. This is free money towards your first home purchase, up to a maximum property value of £450,000.

Keep your savings in a dedicated account separate from your everyday spending. This makes it easier to track your progress and less tempting to dip into your deposit fund.

Getting a Mortgage as a First-Time Buyer

Once you've saved your deposit, the next step is securing a mortgage. As a first-time buyer, you have access to specialist products designed specifically for people buying their first home.

Mortgage Types to Consider

• Fixed-rate mortgages: Your interest rate stays the same for a set period (typically 2-5 years), giving you payment certainty
• Tracker mortgages: Your rate follows the Bank of England base rate, so payments can go up or down
• Discounted mortgages: You get a discount off the lender's standard variable rate for a set period
• Offset mortgages: Your savings are offset against your mortgage balance, reducing the interest you pay

Mortgage Affordability and Stress Testing

Lenders will check that you can afford your mortgage payments if interest rates rise. Most lenders use a "stress test" – they'll check you can still afford payments if rates increase by 2-3% above your agreed rate. This is important because it means you won't be stretched too thin financially.

Getting a Mortgage in Principle

Before you start viewing properties, get a Mortgage in Principle (also called a Decision in Principle). This shows sellers you're a serious buyer and gives you a realistic budget to work within. It's not a formal offer – it's just a preliminary check by the lender that you could borrow a certain amount.

Other Costs of Buying a Home

Stamp duty and your deposit aren't the only costs you'll face. Budget for these additional expenses:

• Solicitor's fees: £800-£2,000 (for conveyancing)
• Surveys: £300-£1,500 (depending on property type and size)
• Mortgage valuation: Usually covered by the lender, but sometimes charged
• Searches: £150-£300 (local authority and water searches)
• Mortgage arrangement fees: £0-£2,000 (depending on the lender)
• Insurance: Buildings insurance and contents insurance

As a rough estimate, budget for an additional 2-5% of your property price to cover these costs on top of your deposit.

Key Dates and Changes in 2026

The most recent significant change to stamp duty came into effect on 1 April 2025. The thresholds were reduced, meaning:

• Repeat buyers now pay stamp duty from £125,000 (previously £250,000)
• First-time buyers now pay stamp duty from £300,000 (previously £425,000)
• First-time buyer relief now applies up to £500,000 (previously £625,000)

These changes mean first-time buyers benefit from relief on a lower threshold but still get substantial protection compared to repeat buyers.

Next Steps: Your First-Time Buyer Checklist

Ready to take action? Here's what to do next:

1. Check your credit score: Get a free credit report from Clearscore, Experian, or Equifax
2. Start saving: Open a Lifetime ISA if you're eligible and set up a regular savings plan

Buying your first home is a marathon, not a sprint. Take your time, do your research, and don't rush into a decision you're not comfortable with. The stamp duty relief available to first-time buyers is a genuine help, but it's just one part of the puzzle. By understanding all the costs involved and planning carefully, you'll be well-positioned to make a successful purchase.
