Can you remortgage when your house value has increased?Yes — and an increase in your property value can significantly improve your remortgage options. When a property rises in value, your loan-to-value ratio (LTV) falls, which typically unlocks better interest rates and may allow you to release equity without moving into a higher LTV band. A higher property value means a lower LTV, which can move you into a cheaper rate band. Every 5% LTV improvement can reduce your interest rate by 0.1–0.3% with many lenders. How does house value affect your remortgage rate?Mortgage rates are priced in LTV bands — typically at 60%, 70%, 75%, 80%, 85%, and 90%. The lower your LTV, the better the rate available. If your property has risen in value since you last mortgaged, your LTV may have dropped into a cheaper band even without any overpayments.
Can you release equity when remortgaging?Yes. If your property has risen in value, you may be able to borrow more — releasing equity — while staying within the same LTV band or a lower one. For example, if your home was worth £300,000 with a £200,000 mortgage (67% LTV) and is now worth £400,000, you could remortgage to £268,000 (67% LTV) — releasing £68,000 in cash. How is the new value established?Your new lender will commission a surveyor's valuation as part of the remortgage process. You cannot self-certify a higher value. Online tools give an indication, but the formal valuation determines what rate band you qualify for. Many remortgage products include a free valuation. What are the costs of remortgaging?
When should you remortgage after a value increase?The best time is 3–6 months before your current fixed deal ends to avoid ERCs. If you are already on your lender's SVR, remortgage immediately — SVRs are typically 7–8%+ and switching to a new fixed deal should save hundreds per month. Verdict Strong case to remortgage if value has jumped A significant property value increase can drop your LTV band, unlock better rates, and allow equity release without worsening your position. Get a broker to model the numbers — a 0.5% rate reduction on £250,000 saves £1,250 per year. Frequently asked questionsDo I need a new valuation to remortgage? Yes. Your new lender will instruct a valuation as part of the application. Many remortgage products offer a free valuation as an incentive. Can I remortgage with the same lender if my value has risen? Yes — this is called a product transfer. Your existing lender may offer a better rate based on the new value, though you should compare the whole market via a broker to ensure you get the best available deal. Does remortgaging affect my credit score? A remortgage application involves a hard credit search, causing a small temporary dip. This typically recovers within 3–6 months and has minimal long-term impact for most borrowers. Can I release equity and reduce my rate at the same time? Yes, if your property value has risen enough to allow additional borrowing while staying in the same or a lower LTV band. A broker can model this for your specific figures. |
