Step 1: Check Your Current Mortgage Details
The first step in any remortgage is to understand your existing mortgage inside and out. You need to know:
- Your current interest rate and the type of product you are on (fixed, tracker, discount, or SVR)
- When your deal expires — this is the date you will move onto the SVR if you do not remortgage
- Your outstanding balance — how much you still owe
- Any early repayment charges — fees you would pay if you leave your current deal before it ends
- Your remaining term — how many years you have left on your mortgage
You can find most of this information on your annual mortgage statement, your original mortgage offer, or by logging into your lender's online portal. If in doubt, call your lender and ask.
This step is essential because it gives you a baseline for comparison. You cannot know whether a new deal is better unless you understand exactly what you are currently paying.
Step 2: Assess Your Property Value and LTV
Your loan-to-value (LTV) ratio is one of the biggest factors in determining what remortgage rates are available to you. It is calculated by dividing your outstanding mortgage balance by your property's current value.
For example:
- Outstanding mortgage: £180,000
- Property value: £300,000
- LTV: 60%
Lenders offer their best rates to borrowers with lower LTVs, with key thresholds typically at 90%, 85%, 80%, 75%, and 60%. Even a small change in LTV — crossing from 76% to 75%, for example — can unlock noticeably better rates.
To estimate your property's value, you can:
- Check recent sale prices of similar properties in your area using online tools
- Ask local estate agents for a free valuation
- Use online property valuation tools (though these are only approximate)
Understanding your LTV helps you set realistic expectations about the rates you will be offered and can even influence whether it is worth overpaying slightly to cross a key LTV threshold before remortgaging.
Step 3: Research the Market and Seek Advice
With your current mortgage details and estimated LTV in hand, you are ready to explore what is available on the market. You have two main approaches:
Use a mortgage broker: A whole-of-market broker can search thousands of deals from hundreds of lenders, including products that are not available to consumers directly. They will assess your circumstances and recommend the most suitable options. This can save you considerable time and potentially money. Most brokers charge a fee, though some are fee-free (earning commission from the lender instead).
Research independently: You can use comparison websites and approach lenders directly. This gives you more control but requires more time and effort. You may also miss out on broker-only deals.
Whichever route you choose, consider the following when comparing deals:
- The headline interest rate
- Any arrangement, booking, or product fees
- Whether the deal includes free legal work and a free valuation
- The total cost over the deal period (rate plus fees)
- Any cashback offers or incentives
- The type of rate (fixed, tracker, or discount)
Do not forget to check what your existing lender is offering through a product transfer — this can sometimes be the simplest and most cost-effective option.
