The Minimum Equity to Remortgage — and What It Means in Practice
The technical minimum equity for a conventional remortgage to a new lender is around 5%, corresponding to a 95% LTV. A small number of specialist lenders will lend at this level, but the product range is very narrow and the rates are significantly higher than at lower LTV bands. For borrowers with only 5% equity, it is often worth comparing the available specialist products against a product transfer from the existing lender, which can be arranged without a new valuation or full affordability assessment.
At 10% equity — 90% LTV — the market is still restricted but meaningfully wider than at 95% LTV. A number of specialist and building society lenders actively serve the 90% LTV remortgage market, and rates, while higher than lower LTV tiers, are competitive within the specialist segment. Borrowers at 10% equity with clean credit and stable income will find workable options available, though they will pay more than at lower LTV bands.
At 15% equity — 85% LTV — the market expands further. More specialist lenders are active at this level, and some near-prime lenders begin to become accessible. For borrowers with straightforward circumstances — clean credit, employed income, standard property — 85% LTV starts to feel like the mainstream specialist market rather than the absolute edge of availability.
Below 5% equity — negative equity territory — remortgaging to a new lender is generally not possible. The only realistic options are to remain with your existing lender and accept their retention products, make overpayments to build equity back above zero, or wait for property values to recover. This is a situation where the existing lender relationship is the primary resource, and direct conversation with your current lender is the starting point.
What 10%, 15%, 20% and 25% Equity Means for Remortgage Options
Understanding the specific implications of different equity levels helps you make a more informed decision about your remortgage options and, if relevant, what steps might improve your position before applying. Each significant threshold in the LTV scale represents a meaningful shift in available products and pricing.
Ten percent equity (90% LTV) gives access to the specialist remortgage market. Products are available but limited, rates carry a significant premium over mainstream levels, and lender criteria are more stringent in areas such as credit profile and income type. This is a functional equity level for remortgaging but represents the toughest tier of the conventional market.
Twenty percent equity (80% LTV) represents a meaningful improvement in lender options. The specialist market is more active at this LTV, and some mainstream lenders begin to become accessible, particularly for borrowers with clean credit and straightforward income. Rate premiums over the best market rates narrow at this level, and product choice improves materially over 90% LTV.
Twenty-five percent equity (75% LTV) is a widely recognised threshold in the mortgage market. It is the point at which most mainstream lenders are fully accessible, rate pricing improves significantly from the 80% tier, and the self-employed and adverse credit markets both open up considerably. If your equity is currently below 25% and approaching this level, there can be real value in making the remaining overpayments or waiting for the threshold to be crossed before remortgaging.
