Introduction
Buying a home in the UK is one of the biggest financial decisions you’ll ever make — and your mortgage rate plays a huge role in how much you’ll ultimately pay. Even a 1% difference in your rate can cost (or save) you tens of thousands over the life of your loan.
So, how do you get the cheapest mortgage rate in the UK in 2025? Whether you’re a first-time buyer, moving home, or looking to remortgage, this guide will walk you through everything you need to know.
What Affects Mortgage Rates in the UK?
Before you can hunt for a low rate, it helps to understand what determines mortgage pricing:
1. Bank of England Base Rate
Mortgage lenders often set their rates based on the BoE base rate. When the base rate goes up, variable mortgage rates usually follow.
2. Loan-to-Value Ratio (LTV)
The more deposit you can put down, the lower your rate. A 60% LTV mortgage will almost always be cheaper than a 90% LTV.
3. Credit Score
A poor credit history will result in higher interest rates or limited options. Lenders reward reliability with better deals.
4. Mortgage Term
Shorter terms (e.g., 15 or 20 years) may come with lower rates, though your monthly repayments will be higher.
5. Fixed vs. Variable Rate
Fixed rates offer certainty, while variable rates can start lower but come with risk.
Fixed vs Variable Mortgage Rates: Which Is Cheaper?
There’s no one-size-fits-all answer, but here’s a quick comparison:
| Feature | Fixed Rate | Variable Rate |
|---|---|---|
| Interest Rate | Usually higher initially | Starts lower, may increase |
| Monthly Payments | Fixed | Can go up or down |
| Budget Certainty | High | Low |
| Long-Term Savings | Depends on base rate trend | May save more if rates fall |
If rates are expected to rise, locking in a fixed rate can protect you. If rates are stable or dropping, a variable rate could save you money — especially with tracker mortgages.
💸 7 Proven Ways to Secure the Lowest Mortgage Rates
1. Improve Your Credit Score
-
Register on the electoral roll
-
Pay bills on time
-
Reduce outstanding debts
-
Avoid new credit applications before applying
2. Increase Your Deposit
The sweet spot is 25% deposit or more. Better LTV = better rates.
3. Compare Multiple Lenders
Don’t just go to your bank. Use:
-
Online comparison tools (e.g. MoneySuperMarket, Compare the Market)
-
Mortgage brokers (see below)
4. Use a Mortgage Broker
Brokers often have access to exclusive deals and can find a lender suited to your financial situation.
5. Choose a Shorter Fixed Term
If you don’t need the full 5-year fix, a 2-year fixed mortgage may come with a lower interest rate.
6. Consider Government Schemes
For first-time buyers:
-
Help to Buy (equity loan)
-
Shared Ownership
-
First Homes Scheme
These can help reduce your required deposit and access better rates.
7. Watch for Timing
Mortgage deals change weekly. If base rates are expected to rise, lock in early. If they’re predicted to fall, you might wait for a better deal.

Tips for First-Time Buyers
Buying your first home? Mortgage rates can be a minefield, but here are some tips:
-
Save at least 10% deposit — but aim for 15% or more if possible
-
Look for first-time buyer deals with cashback or free valuations
-
Consider shared ownership or Help to Buy if struggling with a deposit
-
Use a broker to guide you through the options
Remortgaging for a Better Rate
Already own a home? If your fixed term is ending, it’s time to remortgage — otherwise, you’ll be moved onto your lender’s Standard Variable Rate (SVR), which is usually much higher.
When to Remortgage:
-
3–6 months before your current deal ends
-
If your home value has increased
-
If interest rates are expected to rise
Tip:
Even switching to another product with your current lender (a product transfer) can be easier than starting over and may still lower your rate.
Using a Mortgage Broker: Worth It?
A whole-of-market broker can search across dozens of lenders, including exclusive broker-only deals.
Pros:
-
Saves time and stress
-
Access to more products
-
Expert advice based on your situation
Cons:
-
Some charge fees (typically £300–£500)
-
Not all are “whole of market”
💡 Tip: Look for fee-free brokers like:
-
Habito
-
L&C Mortgages
-
Trussle
Hidden Fees That Can Make a Cheap Mortgage Expensive
Always read the fine print! Some low-rate mortgages include fees that eat into your savings, such as:
-
Arrangement fee: Can be £999 or more
-
Valuation fee
-
Legal fees
-
Early repayment charges (ERCs)
-
Exit/admin fees
Sometimes a mortgage with a slightly higher rate but lower fees can work out cheaper over time.
