Frequently Asked Questions

When should I remortgage?

You should consider remortgaging when your fixed-rate deal ends (typically 2–5 years), when rates have fallen significantly, when your home has risen in value improving your loan-to-value, or when your financial circumstances have improved and you qualify for better deals. Start looking 3–6 months before your current deal expires.

What fees are involved in remortgaging in the UK?

Typical remortgage fees include: arrangement/product fee (£0–£2,000), valuation fee (£0–£500), legal/conveyancing fees (£300–£800), and potentially an early repayment charge (ERC) of 1–5% of the outstanding balance if you leave your current deal early. Some lenders offer fee-free remortgage products.

How much can I save by remortgaging?

Savings vary widely. On a £200,000 mortgage, dropping from 5.5% to 4.5% over a 20-year term could save around £120/month or £1,440/year. Always subtract total fees and divide by monthly saving to find your break-even point before proceeding.

What is an early repayment charge (ERC)?

An ERC is a penalty charged by your current lender if you leave a fixed-rate or tracker deal before the agreed end date. ERCs typically range from 1% to 5% of your outstanding balance and decrease each year of your deal. On a £200,000 mortgage a 2% ERC equals £4,000.

How long does remortgaging take in the UK?

Remortgaging typically takes 4–8 weeks from application to completion. A product transfer with your existing lender can be completed in days. Using a mortgage broker and having documents ready can speed up the process considerably.
