First-time buyers in the UK can typically access mortgage interest rates ranging from around 3.5% to 6.5% or higher, depending on the size of their deposit, the loan-to-value (LTV) ratio, their credit profile, and the type of mortgage product they choose (as of October 2026; rates change frequently, verify current terms with an FCA-authorised lender or adviser before deciding). The most common products are fixed-rate mortgages (locking in the rate for 2, 5, or 10 years), tracker mortgages (following the Bank of England base rate plus a margin), and discount mortgages (offering a discount off the lender’s standard variable rate for an initial period). Your deposit size is the single biggest factor: a 5% deposit usually attracts higher rates (often 5% to 6.5% or more), while a 10% or 15% deposit can bring rates down by half a percentage point or more, and a 25% deposit can unlock the lowest available deals.

How Deposit and LTV Affect Your Rate

Lenders price mortgages in LTV bands. A 95% LTV mortgage (5% deposit) is the riskiest for the lender, so it carries the highest rate. Drop to 90% LTV (10% deposit) and rates improve noticeably. At 85% LTV (15% deposit) or 75% LTV (25% deposit), you access progressively cheaper deals. For example, a lender might offer a 5.8% five-year fix at 95% LTV, 5.3% at 90% LTV, and 4.8% at 75% LTV, as covered in foundational finance texts such as Principles of Finance. Every additional increment of deposit reduces the lender’s risk and can save you hundreds of pounds per year in interest. According to MoneyHelper, building the largest deposit you can afford is one of the most effective ways to lower your borrowing costs and improve your mortgage options (MoneyHelper, 2026).

Types of Mortgage Rates Available

Fixed-rate mortgages are the most popular choice for first-time buyers. They lock your interest rate for a set period (typically 2, 5, or 10 years), giving you certainty over monthly payments regardless of Bank of England base rate changes. At the end of the fixed term, you revert to the lender’s standard variable rate (SVR), which is usually higher, so most borrowers remortgage to a new deal before that happens. Fixed rates offer budgeting stability, which is valuable when you are managing the costs of moving and settling into a new home.

Tracker mortgages follow the Bank of England base rate plus a fixed margin (for example, base rate plus 1.5%). If the base rate falls, your rate and monthly payment fall too. If it rises, your payment increases. Trackers can be cheaper than fixed rates when the base rate is stable or falling, but they carry the risk of payment spikes if rates rise sharply. They suit buyers comfortable with some uncertainty and who believe rates may fall or remain low.

Discount mortgages offer a discount off the lender’s SVR for an initial period (such as 2% off SVR for three years). Because the SVR itself can change at any time, your rate is variable and can move up or down. Discount deals can be attractive if the discount is large, but they are less predictable than fixed rates.

Standard variable rate (SVR) mortgages have no fixed or discounted period and sit at the lender’s discretion. They are rarely the best value for a new borrower and are typically what you revert to once an initial deal period ends.

Other Factors That Influence Your Rate

Beyond deposit size, lenders assess your credit history, income, employment stability, and affordability. A clean credit file with no missed payments or defaults will qualify you for better rates. Lenders also stress-test affordability: they model whether you could still afford the mortgage if rates rose significantly, a regulatory requirement overseen by the Financial Conduct Authority (FCA, 2026). Self-employed buyers or those with irregular income may face slightly higher rates or stricter criteria.

Product fees also matter. Some low-rate mortgages carry arrangement fees of £1,000 or more, which can erode the benefit of a lower rate if you are borrowing a smaller amount. Compare the total cost (rate plus fees) over the initial period, not just the headline rate.

First-Time Buyer Schemes and Support

The UK government’s Help to Buy equity loan scheme for new-build homes closed to new applications in March 2023 (in England), though similar devolved schemes may still operate in Scotland and Wales. The Lifetime ISA remains available: you can save up to £4,000 per tax year and receive a 25% government bonus (up to £1,000 annually) to use toward a first-home deposit (property value up to £450,000). The bonus can boost your deposit and lower your LTV, improving your rate (GOV.UK, 2026).

Some lenders offer specific first-time buyer products with lower fees or accept smaller deposits (such as 5% LTV deals backed by a guarantor or family member’s savings). Speak to an FCA-authorised mortgage adviser to explore what is available for your circumstances.

Where to Compare Rates and Next Steps

Mortgage rates change daily and vary across hundreds of lenders and products. Use a whole-of-market comparison site or consult an FCA-authorised mortgage broker to see the full range of deals. MoneySavingExpert’s mortgage section provides up-to-date best-buy tables and guides for first-time buyers (MoneySavingExpert, 2026). Before applying, obtain an agreement in principle (AIP) from a lender or broker to confirm how much you can borrow and strengthen your position when making an offer.
