Buying your first home in the UK involves navigating multiple financial schemes designed to help you get on the property ladder. From tax relief to government bonuses, understanding these options can save you thousands of pounds and make homeownership more affordable.

1. Stamp Duty Land Tax (SDLT) and First-Time Buyer Relief

Stamp Duty Land Tax is a tax paid on property purchases in England and Northern Ireland. According to HMRC, first-time buyers receive significant relief: you pay no SDLT on properties up to £425,000, and you pay 5% on the portion between £425,001 and £625,000 (HMRC, 2026).

To qualify, you must be purchasing your first residential property, and the purchase price cannot exceed £625,000. If you are buying with a partner, both of you must be first-time buyers. For a £400,000 property, this relief saves you £6,250 compared to standard rates.

Scotland has its own Land and Buildings Transaction Tax (LBTT) with different thresholds, and Wales applies Land Transaction Tax (LTT) with separate rates.

2. Lifetime ISA: A 25% Government Bonus

The Lifetime ISA (LISA) is one of the most powerful tools for first-time buyers aged 18 to 39. You can save up to £4,000 per tax year, and the government adds a 25% bonus on top. That means depositing £4,000 earns you a £1,000 bonus, every year until you turn 50.

According to MoneyHelper, you can use the LISA to buy your first home worth up to £450,000 (MoneyHelper, 2026). You must have held the account for at least 12 months before using the funds for a property purchase. If you withdraw for any other reason before age 60 (except terminal illness), you face a 25% penalty that wipes out the bonus and part of your original savings.

The LISA can hold cash or stocks and shares, giving you flexibility based on your risk tolerance and timeline.

3. Help to Buy ISA (Closed to New Applicants)

The Help to Buy ISA closed to new applicants in November 2019, but if you opened one before that date, you can continue saving until November 2029. The scheme offers a 25% government bonus on savings (up to a maximum bonus of £3,000).

Unlike the Lifetime ISA, the Help to Buy ISA has no property price cap and can be used for homes anywhere in the UK. You receive the bonus at completion, not when you save. If you hold both a Help to Buy ISA and a Lifetime ISA, you can only use the bonus from one scheme for your first home purchase.

4. Shared Ownership Schemes

Shared ownership allows you to buy a share of a property (typically between 25% and 75%) and pay rent on the remaining portion. This reduces the deposit and mortgage you need upfront. You can increase your share over time through a process called “staircasing” until you own the property outright.

These schemes are available through housing associations and are targeted at first-time buyers, key workers, and those whose household income is below £80,000 (or £90,000 in London). The smaller initial stake means you might need a deposit of just 5% to 10% of your share, not the full property value.

Stamp duty is calculated only on the share you are purchasing, and first-time buyer relief applies if you meet the eligibility criteria.

5. Mortgage Guarantee Scheme

The Mortgage Guarantee Scheme helps buyers secure a mortgage with just a 5% deposit on properties up to £600,000. Launched by the government, the scheme reduces lender risk, making 95% loan-to-value mortgages more widely available.

While a 5% deposit (£20,000 on a £400,000 home) is more accessible than the traditional 10% or 15%, you will face higher monthly payments and pay more interest over the mortgage term. Lenders also charge higher interest rates on 95% mortgages to offset the risk.

This scheme is open to all buyers, not just first-time purchasers, and applies to new-build and existing properties.

6. Family Deposit Schemes (Guarantor Mortgages)

Several high-street lenders now offer family deposit schemes where a parent or close relative deposits savings (typically 10% of the property value) into a savings account held by the bank for a fixed period (usually three to five years). This acts as security for the lender, allowing you to borrow up to 100% of the property value with no personal deposit.

The family member’s savings earn interest during the term and are returned at the end, provided you keep up with mortgage payments. If you default, the lender uses the deposited savings to cover the shortfall.

These schemes help buyers who can afford monthly mortgage payments but struggle to save a large deposit, particularly in high-cost regions.

7. Understanding the Full Cost of Buying

Beyond the deposit and stamp duty, budget for additional costs: surveyor fees (£300 to £1,500), mortgage arrangement fees (£0 to £2,000), solicitor or conveyancer fees (£850 to £1,500), and removal costs. You may also need to pay for buildings insurance, local authority searches, and lender valuation fees.

As covered in Principles of Finance (OpenStax, 2022), understanding the total cost of a financial commitment, including hidden fees and long-term interest, is essential before signing a mortgage agreement (OpenStax, 2022).

Final Considerations

Buying your first home is a significant financial commitment. Take time to research mortgage rates, compare lenders, and calculate affordability based on your income and existing debts. The Financial Conduct Authority (FCA) requires lenders to assess affordability rigorously, ensuring you can manage repayments even if interest rates rise.

Consider speaking to an FCA-authorised mortgage adviser who can guide you through the options and find the best deal for your circumstances. Mortgage brokers often access exclusive rates not advertised directly to consumers.
