Frequently asked questions
When should I start looking to remortgage in the UK?
Six months before your current deal ends. Most UK lenders let you lock in a new rate 6 months ahead with no obligation to complete — you can re-book if rates fall.
Are UK remortgages always worth it?
Not always — a large ERC or product fee can outweigh the payment saving. Use the break-even view (fees ÷ monthly saving) to decide.
How long does a UK remortgage take?
Typically 4–8 weeks from application to completion. Product transfers (same lender) can complete in under 2 weeks with no legal work.
Can I remortgage to release equity in the UK?
Yes — this is called capital raising. Common reasons (home improvements, deposit for a second property, debt consolidation) are accepted by most lenders; business or tax reasons need a specialist.
Will remortgaging hurt my credit score?
One hard search on application. A broker's soft-search sourcing means only your chosen lender does a hard search — protecting your file from multiple footprints.
Can I remortgage with bad credit in the UK?
Yes — specialist lenders (Pepper, Kensington, Precise, Vida) price for adverse credit. Rates are higher but often cheaper than staying on SVR. A specialist broker is essential.
Do I need a new valuation to remortgage?
Yes, but most UK lenders now use free automated (AVM) or desktop valuations. Physical valuations are only ordered for high-value, unusual or high-LTV cases.
