Understand the full cost of remortgaging

Remortgaging involves several potential fees. Not all of them apply to every deal, and some lenders waive certain charges as part of their product incentives. Here is a breakdown of each cost you may encounter.

Arrangement fee

This is the fee your new lender charges for setting up the mortgage. It typically ranges from £0 to £1,999. Some of the lowest interest rate deals carry higher arrangement fees, so you need to weigh the total cost over the product term rather than focusing on the rate alone. You can usually add the arrangement fee to your mortgage balance, but this means you pay interest on it for the full term.

Valuation fee

Your new lender needs to confirm the property's value before approving your remortgage. Valuation fees range from £0 to £500, depending on the property value and the lender. Many remortgage deals include a free valuation as a standard incentive.

Legal fees

A solicitor or conveyancer handles the legal transfer of your mortgage from one lender to another. Costs typically range from £300 to £1,000. Many lenders offer free legal work through their own panel solicitors as part of the remortgage package, which saves you this cost entirely.

Deeds release fee (exit fee)

Your current lender charges this to release the title deeds when you leave. It ranges from £50 to £300. This fee is almost always payable regardless of when you remortgage and cannot be avoided.

Mortgage account fee

Some lenders charge an account or booking fee of up to £250 when you apply. This is separate from the arrangement fee and is usually non-refundable, even if your application doesn't proceed. Not all lenders charge it, so check before you apply.

An early repayment charge (ERC) is the biggest potential cost when remortgaging. It applies if you leave your current mortgage deal before the product term ends. For example, if you took a 5-year fixed rate and want to switch after 3 years, your lender will charge an ERC.

ERCs are calculated as a percentage of your outstanding mortgage balance. They typically start at 3% to 5% in the first year and reduce by 1% each year. On a £200,000 balance, a 3% ERC would cost £6,000, a figure that could wipe out any savings from switching to a lower rate.

The most cost-effective time to remortgage is when your current deal is about to expire. Most lenders allow you to apply 3 to 6 months before your deal ends, locking in a new rate without paying an ERC. If you wait until after your deal ends, you'll move onto your lender's standard variable rate (SVR), which is typically 1.5% to 3% higher than the best fixed rates. Check when to remortgage to time your switch and avoid unnecessary charges.

It is possible to remortgage with minimal out-of-pocket costs, although "free" is slightly misleading. Many lenders offer remortgage packages that include a free valuation, free legal work, and no arrangement fee. In these cases, your only cost may be the deeds release fee from your current lender (£50 to £300).

However, fee-free deals sometimes come with slightly higher interest rates. A deal with no arrangement fee at 4.6% might cost more over a 5-year term than a deal at 4.2% with a £999 fee. The key is to calculate the total cost over the product term, including all fees.

A product transfer is another option if you want to avoid most fees. This is where you switch to a new deal with your existing lender. There are no legal fees, no valuation fee, and no deeds release fee. The process is faster and simpler, but you won't have access to the whole market, so you may not get the best rate available.

In most cases, yes. The savings from moving to a lower interest rate usually far outweigh the fees involved. The calculation is straightforward: compare your total costs on the new deal (monthly payments plus fees) against what you would pay by staying on your current rate.

The biggest savings come when you are about to move onto your lender's SVR. If your current fixed rate ends and you do nothing, your payments could jump significantly.

Even after paying £1,500 in fees, you would save over £2,400 in the first year alone. Over a 5-year fixed term, that adds up to nearly £18,500 in savings after fees. The only situation where remortgaging may not be worth it is if you are locked into a deal with a high early repayment charge and the rate difference is small. A remortgage calculator can help you see the exact figures for your situation.

There are several practical ways to bring down the cost of remortgaging.

• Time your switch carefully: Apply 3 to 6 months before your current deal ends to avoid ERCs and prevent a spell on your lender's SVR. Check your mortgage offer to find your exact end date.
• Choose deals with free valuations and legal work: Many lenders bundle these incentives into their remortgage products, saving you £500 to £1,500.
• Compare total cost, not just the rate: A slightly higher rate with no fees can be cheaper overall than a low rate with a £1,999 arrangement fee, especially on smaller mortgages.
• Consider a product transfer: If your current lender offers a competitive rate, transferring to a new deal with them avoids legal and valuation fees entirely. You will not need a new property valuation or solicitor.
• Increase your deposit (lower LTV): If your property has risen in value, you may now fall into a lower LTV band. Moving from 80% to 75% LTV can unlock noticeably better remortgage rates.
• Use a broker: Brokers can negotiate with lenders and often access exclusive deals not available directly. Many brokers are paid by the lender, so you may not pay a broker fee at all.
