When to Consider Switching Lender
The most common time to switch mortgage lender is when your current fixed rate, tracker deal, or discount period ends and you're about to move onto your lender's standard variable rate (SVR). SVRs are typically two to four percentage points higher than the best available deals, so switching can result in substantial savings.
You can also switch mid-deal, but early repayment charges (ERCs) may apply. Calculate whether the savings from a lower rate outweigh the cost of the ERC. In some cases — particularly if rates have fallen significantly — it can still make financial sense to pay the charge and switch early.
The Switching Process Step by Step
Switching mortgage lender follows the same process as a standard remortgage:
- Research and compare: Use comparison sites or a broker to identify the best deals
- Apply for an agreement in principle: Check your eligibility with preferred lenders
- Submit a full application: Provide your documents and undergo a full credit check
- Valuation: The new lender values your property
- Mortgage offer: If approved, you receive a formal mortgage offer
- Legal work: A conveyancer transfers the charge from old lender to new
- Completion: Your old mortgage is redeemed and the new one begins
The whole process typically takes four to eight weeks. Start early — ideally six months before your current deal ends — to ensure a smooth transition.
Costs of Switching Lender
Switching lender involves several potential costs, though many can be offset by the savings you'll make:
- Arrangement fee: Typically £500 to £2,000 (can often be added to the loan)
- Valuation fee: Often free on remortgage deals
- Legal fees: Often free on remortgage deals (the new lender covers them)
- Early repayment charge: Only applicable if you're leaving your current deal before it ends
Always calculate the true cost of switching by comparing the total amount you'll pay over the new deal period (including all fees) against what you'd pay by staying on your current lender's SVR or product transfer options.
What Happens to Your Current Mortgage
When your new mortgage completes, the conveyancer uses the new lender's funds to repay your existing mortgage in full. Your old lender then releases their legal charge on the property, and the new lender registers theirs. From your perspective, your old mortgage simply disappears and is replaced by the new one.
You don't need to do anything to cancel your old mortgage — the legal process handles everything. Your old lender will send you a final statement confirming the mortgage has been redeemed, and your credit file will show the old account as settled and the new one as active.
Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.
