Remortgage Guide: When & How to Switch.

How to avoid the standard variable rate and find a better deal before your fix ends.

Remortgaging means switching your existing mortgage to a new deal — either with your current lender (a product transfer) or with a different lender entirely. Most borrowers should be considering their options at least six months before their current fixed or tracker rate ends, because the window of best deals can close quickly and paperwork takes time.

1

Why remortgage?

The most common reason to remortgage is to avoid reverting to your lender's Standard Variable Rate (SVR). SVRs are set by each lender at their discretion and are typically 2–4% higher than the best available fixed rates. Reverting to an SVR for even a few months costs many borrowers hundreds of pounds unnecessarily.

Other reasons include releasing equity to fund home improvements or other purchases, switching from interest-only to repayment, adding or removing a borrower from the mortgage, or simply securing a better rate as your loan-to-value has improved since your original purchase.

When should you start looking?

Most fixed-rate mortgages allow you to lock in a new rate up to six months before your current deal ends, with the new rate activating on your existing deal's end date. This means you can secure today's rates without paying any early repayment charges (ERCs).

If rates are falling, waiting closer to your end date may work in your favour. If rates are rising or uncertain, locking in early gives you certainty. Your adviser can monitor the market and recommend the right moment to apply.

Early repayment charges

Most fixed-rate and discounted-rate deals carry ERCs if you leave before the deal period ends. These typically range from 1–5% of the outstanding balance — on a £300,000 mortgage, a 2% ERC is £6,000. ERCs are almost never worth paying unless you have a compelling reason to switch immediately.

Tracker and standard variable rate mortgages typically carry no ERCs, giving you complete flexibility to move at any time.

Product transfer vs. full remortgage

A product transfer means staying with your current lender and switching to a new rate they offer. It is faster, involves minimal paperwork, and requires no new valuation or solicitor. It is often the right choice if your circumstances have changed (for example, self-employment income that is harder to evidence) or if the savings from switching lender are marginal after costs.

A full remortgage to a new lender takes longer but gives you access to the whole market. Costs typically include a valuation fee, solicitor fees (sometimes offered free by the new lender), and potentially a product arrangement fee. A whole-of-market broker compares both options and can quantify the net benefit of each path.

How much equity do you have?

Your loan-to-value (LTV) is the ratio of your outstanding mortgage to your property's current value. The lower your LTV, the better the rates available to you. If your property has increased in value since you bought it, you may now sit in a more favourable LTV band — for example, moving from 75% to 70% LTV can unlock a meaningfully lower rate.

You can release equity at remortgage by borrowing more than your outstanding balance — useful for funding renovations, consolidating debt, or other large expenses. Any additional borrowing will be subject to affordability assessment.

6

What documents will you need?

For a full remortgage application, lenders typically require recent payslips (3 months for employed borrowers), P60s, bank statements, and proof of identity and address. Self-employed borrowers will need SA302s or tax calculation documents for the most recent two to three tax years.

Your broker can prepare a full document checklist specific to your employment status and the lender’s requirements, ensuring nothing delays your application.
