How Much Does Remortgaging Cost? The True Total in 2026
Remortgaging isn't free — product fees, legal work, valuations and broker charges all add up. But many lenders now offer incentive packages that cover the main costs. Here's what you'll actually pay in 2026, and when a fee-free deal beats a lower rate.
The Six Costs of Remortgaging
| Cost | Typical range | When it's zero |
|---|---|---|
| Product / arrangement fee | £0–£1,999 | Fee-free products (carry higher rate) |
| Legal / conveyancing fees | £300–£500 | When lender provides free legal service |
| Valuation / survey | £0–£500 | Many lenders waive for standard remortgages |
| Broker fee | £0–£500 | Fee-free brokers (receive lender procuration fee) |
| Mortgage account fee | £0–£300 | Some lenders charge to open/close account |
| Early Repayment Charge | 1%–5% of outstanding balance | Only if you exit a fixed term early |
The biggest wildcard: Early Repayment Charges (ERC). If you're still inside a fixed rate period, exiting early can cost thousands — on a £250,000 mortgage, a 3% ERC = £7,500. Always check your existing deal's terms before comparing remortgage options.
Product Fees: Pay Now or Add to Loan?
Most lenders let you add the product fee to your mortgage rather than paying upfront. This sounds convenient — but you pay interest on it for the life of the loan.
| Product fee | Added to loan at 4.5% | True cost over 25 years |
|---|---|---|
| £500 | Yes | ~£744 |
| £999 | Yes | ~£1,487 |
| £1,499 | Yes | ~£2,231 |
| £999 | Paid upfront | £999 (no interest) |
Rule of thumb: If you're planning to remortgage again in 2–5 years (which most people do), the fee is amortised over a shorter period — add the fee to the loan only if paying upfront would strain your cash flow. If you're keeping the mortgage for many years, pay upfront.
Fee-Free vs Fee-Bearing: When to Choose Which
The standard wisdom is "run the numbers." Here's a worked example for a £250,000 remortgage, 2-year fix:
| Option | Rate | Monthly payment | 24-month total | Product fee | Net cost |
|---|---|---|---|---|---|
| Fee-free | 4.50% | £1,389 | £33,336 | £0 | £33,336 |
| £999 fee | 4.20% | £1,349 | £32,376 | £999 | £33,375 |
| £1,499 fee | 4.00% | £1,320 | £31,680 | £1,499 | £33,179 |
On £250,000, the £999-fee deal is actually slightly more expensive than fee-free over 2 years. The £1,499-fee deal saves £157 — marginal.
Now at £400,000:
| Option | Rate | Monthly payment | 24-month total | Product fee | Net cost |
|---|---|---|---|---|---|
| Fee-free | 4.50% | £2,222 | £53,328 | £0 | £53,328 |
| £999 fee | 4.20% | £2,158 | £51,792 | £999 | £52,791 |
| £1,499 fee | 4.00% | £2,112 | £50,688 | £1,499 | £52,187 |
On £400,000, paying a £999 fee saves £537 net; the £1,499 fee saves £1,141 net. Worth it.
Crossover point: Generally, fee-bearing products start to beat fee-free at roughly £150,000–£200,000+ loan balance — varies with the specific rate difference.
Legal Fees: How to Minimise Them
Option 1: Use the lender's free legal service
Most major lenders (Nationwide, Halifax, Santander, NatWest, Barclays) offer a free standard legal service for remortgages — they instruct a panel conveyancer at their cost. This covers:
- Register of title search
- Official copies of register entries
- Mortgage deed execution
- Registration of new charge at Land Registry
Not suitable if:
- You're adding or removing a borrower
- There are unusual title conditions
- You're transferring equity
Option 2: Cashback to cover legal fees
Some lenders offer £250–£500 cashback specifically to offset legal costs. Effectively the same as free legals but you get flexibility to choose your own solicitor.
Option 3: Pay your own solicitor
When the remortgage is more complex, or you want a named solicitor rather than a panel firm. Expect £350–£600 for a standard residential remortgage.
Product Transfer vs Full Remortgage
A product transfer means switching to a new deal with your existing lender when your fixed rate ends — without changing lender.
| Product transfer | Full remortgage (new lender) | |
|---|---|---|
| Solicitor needed | No | Usually (often provided free) |
| New valuation | Usually not | Often (often free) |
| Application complexity | Low — online or phone | Full application, income verification |
| Speed | Days | 4–8 weeks |
| Rate options | Limited to your lender's range | Whole market |
| Typically cheaper? | Often yes for smaller balance | Often yes for competitive rate-hunting |
Product transfers are underrated. If your current lender is competitive on rate, a transfer is the cheapest and fastest option. Only move lender if the rate saving clearly outweighs the additional cost and hassle.
Total Cost Scenarios: What You'll Likely Pay
| Scenario | Product fee | Legals | Valuation | Broker | Total cost |
|---|---|---|---|---|---|
| Product transfer (same lender) | £0–£999 | £0 | £0 | £0 | £0–£999 |
| Fee-free remortgage + free legals | £0 | £0 | £0 | £0 | £0 |
| Standard remortgage with broker | £999 | £0 (free) | £0 (free) | £300 | £1,299 |
| Full independent process | £1,499 | £450 | £300 | £500 | £2,749 |
| Early exit (3% ERC on £250k) | £7,500 ERC | £0–£450 | £0–£300 | £0–£500 | £7,500–£8,750 |
The ERC scenario illustrates why timing is everything — exiting a fix early to get a lower rate rarely makes mathematical sense.
Using a Broker: Paid vs Fee-Free
Fee-free brokers (L&C Mortgages, Habito, Trussle) earn a procuration fee from the lender — usually 0.3–0.5% of the loan. They're not completely independent (they have incentives to use certain lenders), but they access the whole market and charge you nothing.
Fee-charging brokers (typically independent whole-of-market advisers) charge £300–£750 typically. They may access exclusive deals not available to fee-free brokers, and their advice tends to be more detailed for complex situations (self-employed, unusual income, large portfolio landlords).
For a straightforward residential remortgage, a fee-free broker is usually sufficient.
