An estimated 800,000 UK borrowers sit on their lender's Standard Variable Rate at any given time. The SVR is almost always the most expensive rate, typically 2% to 4% above the best fixed deals.\n\nThe Remortgage Timeline — Start shopping 6 months before your current deal expires. Most mortgage offers are valid for 6 months, so lock in a rate now and complete when your deal ends. If rates fall between locking in and completion, you can usually withdraw and apply for the cheaper deal.\n\nProduct Transfer vs Full Remortgage — A product transfer switches to a new deal with your existing lender. It is faster (often same-day), cheaper (no legal or valuation fees), and simpler. A full remortgage to a new lender gives access to the whole market but takes 4 to 8 weeks. Compare both — sometimes the product transfer wins on total cost even at a slightly higher rate.\n\nRate Lock Strategy — In a rising environment, lock in early. In a falling environment, wait but keep a fallback offer in place. Some brokers manage two applications simultaneously — one product transfer and one full remortgage — and proceed with whichever is cheaper.\n\nWhen Not to Remortgage — If your balance is very small (under 50,000), fees may outweigh savings. If your property has fallen in value, your LTV may have worsened. If circumstances changed, a product transfer may be safer as retention deals often have lighter affordability checks.\n\nThe Cost of Doing Nothing — If your fixed rate is 4.2% and the SVR is 7.5%, on a 200,000 balance that is an extra 550 per month. Even a 999 arrangement fee pays for itself in under two months. Set a calendar reminder 6 months before your deal ends.
