When Should I Remortgage? UK 2026

Start looking 3-6 months before your current deal ends. Many mortgage offers last 3-6 months (Nationwide offers 6 months, HSBC/Barclays typically 3 months), meaning you can lock in a rate now to complete later. If rates fall before completion, better to renegotiate. Starting early is crucial because: the remortgage process takes 4-8 weeks, survey and valuation add time, and solicitors have varying workloads. If your deal expires and you haven't remortgaged, you'll slip onto the Standard Variable Rate (SVR) - typically 3-4% higher than fixed deals. Even a week on SVR on a £200,000 mortgage costs roughly £60-80 extra.

An Early Repayment Charge (ERC) is a fee your lender charges if you leave your mortgage deal before the fixed period ends. Typical ERCs are 1-5% of your outstanding mortgage, declining over the fixed period. Example: a 5-year fix might have 5% ERC in year 1, 4% in year 2, down to 1% in year 5. On a £250,000 mortgage, a 3% ERC is £7,500. ERCs are usually the main barrier to switching early. Calculate whether rate savings exceed ERC costs - if you'd save £200/month by switching and wait 12 months, saving £2,400, it's worth paying a £1,000 ERC to switch. Tracker mortgages typically have no ERCs.

The SVR is the lender's default rate, which you automatically move to when your fixed or tracker deal expires. SVRs are set independently by each lender (unlike the Base Rate, which is set by the Bank of England) and are typically 4-5% higher than competitive fixed deals. In 2024-25, many lenders' SVRs are around 7-8% while competitive 5-year fixes are around 4-5%. On a £200,000 mortgage, the difference between a 4.5% fix and 7.5% SVR is roughly £300/month. There's almost never a good reason to stay on SVR - always remortgage or switch product with your current lender. SVRs also change with no notice and aren't linked predictably to Base Rate changes.

A product transfer (also called a rate switch) means staying with your current lender but moving to a new deal. A remortgage means switching to a new lender entirely. Product transfer advantages: faster (days not weeks), no solicitor required, no credit check in most cases, your existing mortgage terms are maintained, no application form. Remortgage advantages: access to the entire market (potentially cheaper rates), can borrow more or restructure, can change term length. If your current lender's best rate is competitive, a product transfer is usually simpler and just as good. Use a broker to compare both options - brokers have access to lender-specific rates not available directly.

Remortgaging involves a hard credit search (which records on your credit file and is visible to other lenders for 12 months). Multiple hard searches in a short period (such as applying to several lenders directly) can temporarily lower your score. However, using a mortgage broker typically means one hard search. The impact is usually minor and temporary - typically a small dip for 3-6 months. Having multiple mortgage applications in the same 14-30 day window is often treated as a single search for credit scoring purposes. Long-term, successfully managing a mortgage is one of the most positive factors for your credit score. Using a mortgage agreement in principle (AIP) only typically triggers a soft search.

Yes, for most people a broker is strongly recommended. Brokers have access to lender-specific rates and products unavailable directly to consumers, can search the whole market at once, handle the application paperwork, provide regulated advice (meaning you have recourse if given bad advice), and are often paid by the lender (fee-free to you). Whole-of-market brokers like L&C Mortgages, Trussle, and Habito are free to use online. High street advisers at banks can only offer their own products. A broker comparing hundreds of deals may find a 0.2-0.5% better rate than you'd find yourself - on a £250,000 mortgage that's £500-£1,250/year.

Yes - equity release through remortgaging (not to be confused with equity release products for over-55s) is common. You borrow more than your current outstanding mortgage balance, and the extra cash is released to you. This is used for home improvements, debt consolidation, or major purchases. Considerations: you'll need sufficient equity (typically must maintain at least 20% LTV for best rates), the larger mortgage means higher monthly payments and more interest over the term, and your new LTV band affects your interest rate (60% LTV deals are cheaper than 75% or 85% deals). Home improvements that add value can be self-funding - a £20,000 kitchen extension that adds £40,000 of value while your mortgage payments increase by £80/month.
