Remortgaging: When to Start and What to Expect

17 Sep 2026 · 4 min read

Starting the remortgage process at the right time can save thousands. Here's our guide to timing, process, and what to watch for.

When should you start?

Earlier than most people expect. Most lenders will issue a mortgage offer valid for 3–6 months, which means you can lock in a rate today without completing until your current deal ends. If your fixed rate expires in March, you should be speaking to a broker in September or October at the latest. This gives you rate certainty without any urgency, and eliminates last-minute scrambling when your fixed term ends.

What happens if you leave it too late?

When your fixed rate ends, you automatically move onto your lender's Standard Variable Rate — typically 1.5–2.5% higher than your previous fixed rate. Every month you spend on SVR is money overpaid. We see clients who have been on SVR for months, sometimes longer, without fully realising the cost. The calculation is simple: if your mortgage is £250,000, a 2% increase in rate costs over £400 per month.

Product transfer vs full remortgage

Your current lender will likely contact you with a product transfer offer as your deal approaches its end. Product transfers are quick, require no legal work, and your lender already holds all your information. But they're offering you one range of products from one lender. A full remortgage searches the whole market and may produce a significantly better rate. We compare both options for every client — and frequently the whole-of-market search wins.

How long does a remortgage take?

A straightforward remortgage with a new lender typically takes 4–8 weeks from application to completion. If your property needs a valuation, your income is complex, or there are legal complications, allow 8–12 weeks. This is another reason to start early — rushing a remortgage at the last minute significantly limits your options and can result in lender selection driven by speed rather than rate.
