How to Remortgage Your Home: Step-by-Step Guide

A remortgage means switching your existing mortgage to a new deal — either with your current lender (a "product transfer") or by moving to a new one (a "remortgage"). Most homeowners do this every 2–5 years to avoid being dropped onto a much more expensive standard variable rate.

Done well, a remortgage takes 4–8 weeks and can save you thousands. Done late, you pay your lender's SVR for months while the process catches up.

This guide is the start-to-finish playbook.

Step 1: Know your end date

Your fixed or tracker mortgage has a clear "deal end date" — usually 2, 3 or 5 years after you took it out. After that date, your lender automatically rolls you onto their standard variable rate (SVR), which in 2026 is typically 6.5–8.5% — far above any decent fixed deal.

Find your end date in your most recent annual mortgage statement, your original mortgage offer letter, or your online banking app.

Start the remortgage process 6 months before this date. That's when you can lock in a new rate without paying early repayment charges and without overlapping with SVR.

Step 2: Decide product transfer or full remortgage

You have two paths:

Product transfer (PT) — your existing lender offers you a new deal on your existing loan. No legal work, no valuation, no credit check.

Remortgage — you apply to a different lender. New legal work, new valuation, new affordability checks.

Factor Product transfer Remortgage
Speed Days 4–8 weeks
Legal fees None ~£300 (often free with cashback)
Valuation None Lender often pays
Credit check Light Full
Affordability check Often skipped Required
New rates available Lender's rates only Whole market
Borrow more Limited Yes

Use a product transfer if you only want a like-for-like deal and your lender's offer is competitive. Use a remortgage if there's a much better rate elsewhere or you want to borrow more (e.g. to consolidate debt or fund renovations).

Step 3: Work out what you can borrow

For a like-for-like remortgage on the same balance, affordability is usually straightforward — you've been making payments, your income has likely grown, and the property has probably risen in value.

If you want to borrow more (capital raising), the new lender will assess affordability afresh. They'll ask:

  • Why you want the extra (renovations, debt consolidation, gift to family — all common, all acceptable)
  • Your current income and outgoings
  • Your other debts

Borrowing more for debt consolidation requires careful thought — you're swapping unsecured debt (credit cards) for secured debt (your house). See Remortgage to consolidate debt.

Step 4: Check your loan-to-value

The lower your LTV, the better the rate. Two things may have moved your LTV since you last took out a mortgage:

  • You've paid down some of the loan (lowers LTV)
  • Your house has gone up or down in value (changes LTV)

Check current value via Rightmove sold prices, Zoopla estimates, or get a free desktop valuation from Habito or another online broker. If you crossed below 60%, 75%, 80% or 85% LTV thresholds since taking the original mortgage, you'll qualify for materially better rates.

Step 5: Compare deals

Two routes:

  1. Direct to your lender first, to see their product transfer offer
  2. Through a broker to scan the rest of the market

A whole-of-market broker (Habito, L&C, Mojo, John Charcol etc.) will compare your lender's PT offer against the rest of the market and tell you whether moving is worth it.

Look for:

  • Headline rate
  • Arrangement fee (£0–£1,995)
  • Cashback offered (often £250–£500 on remortgages)
  • Free legals, free valuation
  • Tie-in length
  • Early repayment charges

Don't fixate on rate alone — a £999 fee on a 5-year £200,000 mortgage adds £200/year to your effective cost. A 0.05% rate difference is worth ~£100/year, so the no-fee deal often wins.

Step 6: Apply

Once you've chosen, apply through the broker (or directly). You'll need:

  • 3 months of payslips
  • 3 months of bank statements
  • ID and proof of address
  • Latest mortgage statement (for the existing balance)
  • Buildings insurance details

The new lender runs a hard credit check, instructs a valuation (usually free), underwrites the application, and issues an offer in 2–4 weeks.

Documents checklist: Documents needed for a mortgage application.

A remortgage requires conveyancing — but it's much lighter than a purchase. The conveyancer:

  • Reviews the title
  • Pays off your old mortgage from the new loan
  • Registers the new mortgage at the Land Registry
  • Sends you any surplus (if you raised capital)

Most lenders include "free legals" on remortgage products, where they appoint a panel solicitor at their cost. This is convenient but slow (3–6 weeks typically). Paying a private conveyancer (~£300–£500) often shaves 2 weeks off.

Step 8: Completion

Completion on a remortgage is uneventful — there's no key handover. The new lender pays off the old one, the old mortgage closes, the new one starts. Your direct debit changes amount and date.

You'll get:

  • A new mortgage offer letter
  • Confirmation from the conveyancer of completion
  • A welcome letter from the new lender with your new account details

Common remortgage mistakes

  • Waiting until the deal ends — you go onto SVR for weeks while the new mortgage processes
  • Letting the lender auto-roll you — many quietly hope you'll do nothing and pay SVR
  • Comparing on rate alone — fees and tie-in length matter
  • Forgetting early repayment charges — if you're still in your fixed period, ERCs of 1–5% may apply. See remortgage early repayment charges
  • Not telling the new lender about a major life change — divorce, new job, new debt — they will find out, better volunteered

When NOT to remortgage

  • You're inside the fixed period and the ERC outweighs the saving
  • You only have 12 months left on the term and the SVR for that short period is cheaper than ERCs + fees on a new product
  • Your circumstances have deteriorated (job loss, payment trouble) — speak to your lender first about forbearance, not a new product
  • The amount outstanding is below most lenders' minimum (£25k threshold is common)

Frequently asked questions

How long does a remortgage take? Typically 4–8 weeks. Allow 8–12 if you're remortgaging to a smaller, slower lender.

Can I remortgage early? Yes, but you'll pay early repayment charges if you're inside your fixed period. Most lenders let you secure a new deal up to 6 months before your end date, with no ERC.

Will I need a new valuation? Most remortgage products include a free desktop valuation. Some require a physical valuation, particularly above 85% LTV.

Can I remortgage if my house has fallen in value? Yes, if you still have at least 5–10% equity. Below that, your lender may insist you stay on a product transfer rather than moving to a new lender.

What if I'm self-employed? You can remortgage, but expect closer scrutiny — typically 2–3 years of accounts. See Remortgaging when self-employed.

Should I remortgage or stay on SVR temporarily? Almost never SVR for any meaningful time — it's the highest rate the lender offers. If you can't remortgage immediately, ask your lender for their best PT rate.
