How remortgaging works in the UK

A remortgage is a legal and underwriting process as much as a rate shopping exercise. Here is the usual sequence.

  1. Research and true-cost compare. Look beyond the headline rate — fees, ERC, cashback and LTV band matter. Use the true cost calculator.
  2. Agreement / Decision in Principle. Soft or hard credit checks vary by lender; an AIP indicates a likely maximum before full application.
  3. Full application. Income, outgoings, credit and property details go to underwriting. Be ready with bank statements and ID.
  4. Valuation. The new lender values the property (desktop, drive-by or full survey). Your LTV can shift if the valuation differs from your estimate.
  5. Mortgage offer. Once issued, you usually have a validity window. Read fees, ERC and overpayment rules carefully.
  6. Legal work and completion. Conveyancers redeem the old mortgage and register the new charge. Timing completion to your ERC end date avoids unnecessary charges.

Product transfers skip much of this (often no new valuation or conveyancer), which is why they can win on speed and fees even when the rate is not the absolute cheapest — compare properly rather than assuming.
