The remortgage process explained step by step

Remortgaging means replacing your current mortgage with a new one, either with the same lender or a different one. Your property stays the same and you continue living there. The new mortgage pays off the old one, and you start making payments on the new terms instead.

People remortgage for several reasons:

• To get a lower interest rate: When your fixed or tracker deal ends, you move onto your lender's standard variable rate (SVR), which is almost always higher. Switching to a new deal can save hundreds per month.
• To reduce monthly payments: A lower rate or longer term brings payments down, freeing up money for other priorities.
• To borrow more: You can remortgage to release equity for home improvements, paying off other debts, or other large expenses.
• To switch to a different deal type: Moving from a variable rate to a fixed rate gives you payment certainty, or vice versa.
• To change your mortgage term: Shortening your term means paying less interest overall, while extending it reduces monthly payments.

Around 1.6 million UK homeowners remortgaged in 2025, according to UK Finance. The most common reason was to avoid moving onto an expensive SVR after a fixed deal ended.

The remortgage process follows a clear sequence from start to finish. Understanding each step helps you plan ahead and avoid delays.

Step 1: Check your current mortgage deal

Start by reviewing your existing mortgage terms. Find out when your current deal ends, what your lender's SVR is, and whether you have any early repayment charges (ERCs) remaining. Your latest mortgage statement or online account will show these details. ERCs typically range from 1% to 5% of the outstanding balance and reduce each year of your deal.

Step 2: Compare new mortgage deals

Look at what rates are available across the market. A whole-of-market mortgage broker can search deals from over 90 lenders, including exclusive rates not available directly. Consider the total cost of the deal, not just the interest rate: factor in arrangement fees, valuation fees, and any cashback offers.

Step 3: Apply for the new mortgage

Your broker submits your application to the chosen lender with all supporting documents. The lender runs a credit check and affordability assessment. This typically takes 2 to 5 working days for an initial decision.

Step 4: Property valuation

The new lender values your property to confirm it provides adequate security for the loan. Many remortgage deals include a free valuation. For straightforward cases, some lenders accept a desktop valuation using data from previous sales and local market information, which speeds up the process. A physical valuation involves a surveyor visiting your property and usually takes 1 to 2 weeks to arrange and complete.

Step 5: Legal work (conveyancing)

A solicitor or conveyancer handles the legal transfer from your old mortgage to the new one. Many lenders offer free legal work as part of their remortgage deal, using their own panel solicitors. The solicitor carries out property searches, checks the title deeds, and prepares the transfer documents. This stage typically takes 2 to 4 weeks and is the most common cause of delays.

Step 6: Completion

On completion day, your new lender sends the funds to pay off your old mortgage. Your solicitor handles the transfer and registers the new mortgage with the Land Registry. Your old mortgage is closed and you start making payments to your new lender from the following month. You don't need to do anything on the day itself: the process happens between the lenders and your solicitor.

The total timeline depends on several factors, but you can plan around these typical timeframes for each stage of the process.

Several factors can speed things up or slow them down:

• Product transfers (staying with your current lender) can complete in as little as 1 to 2 weeks because the lender already holds your details and may not require a new valuation or legal work
• Desktop valuations avoid the need to arrange a surveyor visit, saving 1 to 2 weeks
• Free legal services provided by the lender can sometimes move faster because they handle high volumes of remortgage cases
• Complex situations such as self-employed income, leasehold properties with short remaining terms, or properties with non-standard construction can add 2 to 4 weeks

Starting the process 6 months before your current deal ends gives you time to lock in a rate without rushing. Most mortgage offers are valid for 3 to 6 months, so an early start doesn't mean you'll lose the deal.

Remortgaging involves several potential costs. Not all of them apply in every case, and many lenders offer deals that waive some fees entirely.

The biggest potential cost is the early repayment charge. If you remortgage during your fixed or discounted period, this can run into thousands of pounds. On a £200,000 mortgage with a 3% ERC, that is £6,000. Timing your remortgage to coincide with the end of your deal avoids this charge entirely.

Many competitive remortgage deals include free valuation and free legal work, which can save you £1,000 to £2,000. When comparing deals, always calculate the total cost over the deal period (rate plus fees) rather than focusing on the interest rate alone. A deal with a slightly higher rate but no fees can work out cheaper overall than a low-rate deal with a £1,999 arrangement fee.

Use a remortgage calculator to compare the total cost of different deals including all fees and charges.

Lenders need to verify your identity, income, and existing financial commitments. Having everything ready before you apply prevents delays during the process.

• Proof of identity: Valid passport or full UK driving licence
• Proof of address: Utility bill or bank statement from the last 3 months
• Income evidence: Last 3 months' payslips and your latest P60 for employed applicants. Self-employed applicants need 2 to 3 years of SA302 tax calculations and corresponding tax year overviews from HMRC
• Bank statements: Last 3 months showing salary credits and regular outgoings
• Current mortgage statement: Your latest annual statement or a recent monthly statement showing the outstanding balance, current rate, and deal end date
• Details of other debts: Credit cards, loans, car finance, or any other financial commitments

If you are remortgaging to borrow additional funds, the lender may ask for evidence of how you plan to use the money. For home improvements, this could include builder quotes. For debt consolidation, you will need statements showing the debts you plan to clear.

The best time to start looking at remortgage options is 6 months before your current deal ends. This gives you enough time to compare the market, apply, and complete the process without rushing or falling onto your lender's SVR.

Key timing considerations:

• Most lenders let you lock in a rate 3 to 6 months early. Your new deal doesn't start until your current one ends, so you don't pay two mortgages or lose your existing rate early.
• Mortgage offers are valid for 3 to 6 months. If rates drop further after you've secured an offer, many brokers can switch you to a better deal before completion.
• Avoid your lender's SVR. SVRs averaged 7.85% in early 2026, compared with around 4.3% for a typical 2-year fixed deal. On a £200,000 mortgage, that is roughly £400 per month more in payments.

If you are already on your lender's SVR, you can remortgage at any time without early repayment charges. There is no penalty for being on the SVR, but every month you stay on it costs you more than a competitive fixed or tracker rate.

Consider a product transfer if your current lender offers competitive rates. Product transfers are faster (often completing in 1 to 2 weeks) and involve less paperwork, though you may miss better deals available elsewhere in the market.
