The short answer

How do you remortgage a London home?

Start with your current mortgage statement and deal end date. Ask your lender what it offers you as an existing customer, then compare that with a mortgage from another lender over the same period. Include product fees, any early repayment charge, legal or valuation costs and the effect of changing the term. A new lender will assess your finances and the property before making an offer.

First decide what needs to change. A new interest-rate deal, extra borrowing, a different term or a change of borrower can involve different checks. Tell an adviser about the whole plan at the outset.

MoneyHelper's remortgaging guide explains the current-lender comparison and the costs of switching.

Choose the route

Stay, switch or borrow more?

Stay with your lender

A product transfer changes your mortgage deal with the current lender. It may involve less paperwork for a straightforward switch, but the lender decides what checks are needed and which deals are available to you.

Ask about the new rate, product fee, term, repayment type, switch date and any charge for changing your current deal.

Move to a new lender

A remortgage replaces your existing loan. The new lender will assess affordability and the home, and legal work is normally involved. The headline rate is only one part of the comparison.

Check the total cost over the period you expect to keep the deal, including fees and any charge to leave the old one.

Borrow more

Ask whether a further advance from the current lender or a larger remortgage fits your purpose and budget. Extra borrowing brings further affordability and property checks and can increase what you repay overall.

If the money is for unsecured debts, consider the risk of securing them on your home and seek independent debt advice where needed.

Changing borrower names, the mortgage term or the property's use needs its own review. Our national remortgage page covers the broader service; this page focuses on the London homeowner's decision.

Run the numbers

Compare cost, timing and future plans

Get a current balance, deal end date and redemption statement from your lender. Then compare likely payments and total costs for each realistic option over the same timeframe. Check whether a product fee is paid now or added to the mortgage, whether an early repayment charge applies and who pays any valuation or legal costs. Confirm the figures before applying: rates, fees and lender offers change.

Deal ending

Find out when your existing rate ends and what follows it. Ask both the current lender and any new lender when a new deal could start. Do not assume a reserved rate or offer will remain available indefinitely.

Moving or changing plans

If you may sell, move, let the property or make a large overpayment, examine early repayment charges and flexibility before taking another deal. Porting to a new home, where offered, still needs a fresh assessment.

Lower monthly payment

A longer term can reduce the monthly payment while increasing the amount repaid over time. A lower headline rate can still cost more once product and switching fees are included.

Illustrative calculation, not a lender decision

Understanding estimated loan-to-value

If your mortgage balance were £300,000 and the home were worth £500,000, the estimated loan-to-value would be 60%: £300,000 divided by £500,000. A lender may value the property differently, and extra borrowing or added fees would change the ratio. This example does not indicate eligibility, a rate or how much you could borrow.

London-specific checks

Will the property affect your options?

The lender assesses the particular home as security, not simply its postcode or an online valuation. If yours is a leasehold flat, high-rise building, ex-local authority property or an unusual conversion, raise that early. A change in value may also alter your estimated loan-to-value.

Flat and lease

  • How much time remains on the lease?
  • Have service charges, ground rent or planned major works changed?
  • Is building-safety information available where relevant?
  • Will a solicitor need to resolve a title or lease issue?

GOV.UK's leasehold guide explains why these details matter.

Change of use or borrowing purpose

  • Tell the adviser if the property is now or may soon be let.
  • Explain any planned extension, conversion or other substantial works.
  • Identify whether you need to borrow more and what the money is for.
  • Make sure the current lender knows about any change its terms require you to report.

London buy-to-let remortgaging has a separate owner.

Different checks have different owners. Count Ready can explore mortgage criteria. The lender makes its own valuation and lending decision; a solicitor checks legal title and lease matters. High-rise flat guidance covers that property type in more detail.
Before you apply

What should you bring to an initial conversation?

1

Current deal

Balance, lender, rate end date, remaining term, repayment type and any stated early repayment charge. Note if you have already reserved a new rate.

2

Your plans

Whether you want a new rate only, more borrowing, a changed term or borrower, or expect to move or let the home. Say what monthly payment feels manageable.

3

Income and property

Broad income and commitments, property type, estimated value and known lease or building issues. Formal income and property evidence is requested securely if an application progresses.

If your income has changed or you have a credit concern, ask about the realistic routes before another application. Self-employed London homeowners and London credit concerns have their own detailed pages.

Straight answers

London remortgage questions

Is a product transfer the same as a remortgage?

A product transfer is a new deal with your existing lender. A remortgage usually means replacing your loan with one from another lender. Compare both where available, including fees, term, flexibility and any extra borrowing need.

Can I remortgage before my fixed deal ends?

You can ask about switching early, but your present mortgage may have an early repayment charge. Ask the lender for the exact charge and date it ends, then compare the full cost before deciding.

Do I need a deposit to remortgage?

You do not normally pay a purchase deposit when replacing a mortgage on a home you already own. The lender considers the new loan against its valuation of the property, alongside affordability and other criteria. You may still need cash for fees or to reduce the balance.

Can I remortgage a London leasehold flat?

Possibly. The remaining lease term, charges, building information, valuation and lender policy can affect the case. Tell the adviser about known issues early and obtain legal advice for the lease itself.

What if my income has fallen since I took out the mortgage?

A new lender will assess your current circumstances. Ask your existing lender about its available product transfers too; the checks for a straightforward switch can differ from those for a new mortgage or extra borrowing. No route is guaranteed.

Can I remortgage to pay off other debts?

It may be possible, but turning unsecured debts into mortgage borrowing puts your home at risk and can increase total interest over a longer term. Consider other options and free debt advice before deciding. MoneyHelper explains the risks.
