Is it better to pay a mortgage product fee or take a higher rate?

It depends entirely on how much you are borrowing, and for most first-time buyers the fee-free deal wins. A product fee is a flat cash amount, but the rate saving it buys you is a percentage of your loan. On the Moneyfacts first-time buyer best buys as at 5 August 2026, West Brom BS charged 4.78% with a £1,499 fee at 90% LTV while first direct charged 4.99% with no fee. The 0.21 percentage point gap is worth about £24 a month on a £200,000 mortgage, so the fee needs roughly five years to pay for itself on a two-year deal. Work out your own break-even before you apply: multiply your loan by the rate difference, divide by 12, then divide the fee by that monthly saving. If the answer is more months than your fix lasts, take the fee-free deal.

How do I work out if a mortgage arrangement fee is worth paying?

Compare the total cost over the fixed period, not the monthly payment. Add the fee to the payments you will make during the fix, then add the balance you will still owe at the end. The deal with the lower combined figure is the cheaper one. On a £200,000 mortgage over 25 years, a 4.78% deal with a £1,499 fee leaves you £220,226 worse off after two years once fee, payments and remaining balance are counted, against £219,562 on a fee-free 4.99%. The fee-free deal wins by £664. Run the same sum at your own loan size, because the answer flips as the loan gets bigger. Our mortgage calculator will give you the monthly payments for both rates in under a minute.

Should I add the mortgage product fee to my loan or pay it upfront?

Pay it upfront if you possibly can. Adding a fee to the loan does not make it disappear, it just spreads it over the full mortgage term and charges you interest on it the whole way. A £1,499 fee added to a 25-year mortgage at 4.78% costs about £8.57 a month, which is roughly £2,571 by the end of the term, so the fee has grown by around £1,072. Lenders present this option as convenient because it removes a cash hurdle at completion, and if paying upfront would leave you with no emergency savings then adding it is defensible. Otherwise, treat the loaded fee as what it is: borrowing at your mortgage rate for 25 years to buy a discount that lasts two.

Do fee-free mortgages always have higher interest rates?

Almost always, yes, because the lender has to recover the cost somewhere. The question is whether the higher rate costs you more than the fee would have. On smaller loans it usually does not. Moneyfacts figures from March 2025 put the average product fee on a fixed rate deal, excluding no-fee products, at £1,129, with 36% of fixed deals carrying no product fee at all, down from 41% in 2020. That means roughly one deal in three is fee-free and worth checking, and the number has been shrinking. Ask your lender or broker for the fee-free version of any deal you are quoted, then compare total cost over the fix rather than the headline rate. On a first-time buyer loan under about £200,000, the fee-free option is the one to beat.

4.78% vs 4.99%: the £1,499 fee trap

You've got two mortgage deals open in two browser tabs and you're doing the thing everyone tells you to do: picking the lower number. One says 4.78%. The other says 4.99%. It feels like a decision that takes four seconds, and every guide you've read says the cheapest rate wins. So you're about to pick 4.78%, and nobody has mentioned that on the loan you're actually taking, it's the more expensive of the two.

On a £200,000 mortgage over 25 years, the 4.78% deal leaves you £664 worse off after two years than the 4.99% one. Not because of anything hidden in the small print, but because of a £1,499 product fee sitting in plain sight next to a number you weren't reading.

The two deals in front of a first-time buyer this week

These aren't hypothetical products. Both sit on the Moneyfacts first-time buyer best buy tables as at 5 August 2026.

The first is West Brom BS at 4.78%, fixed until 31 October 2028, up to 90% loan to value, with a £1,499 product fee. It's the lowest 90% LTV rate a first-time buyer can get this week, and it's the one that appears at the top of any table sorted by rate.

The second is a first direct fee-saver at 4.99%, a two-year fix, also up to 90% LTV, with no product fee and a free valuation (Moneyfacts, 5 August 2026). It's 0.21 percentage points more expensive and it looks, at a glance, like the worse deal.

The gap between them is 0.21 percentage points. On £200,000 that's £24.33 a month: £1,143.69 against £1,168.02. That's real money, and if the fee didn't exist the lower rate would win comfortably. So the whole question is whether £24.33 a month buys back £1,499, and on a two-year deal the answer is no: you'd need 62 months of that saving, and you've only got 24.

£1,499 buys you £24.33 a month

The reason product fees catch people out is that a fee is a flat cash amount while the rate discount it buys is a percentage of your loan. Big loan, big discount. Small loan, small discount, same fee.

Here's the full two-year comparison on a £200,000 repayment mortgage over 25 years, counting the fee, every payment made during the fix, and the balance still outstanding at the end.

The maths, in one place: £200,000 over 24 months

West Brom BS, 4.78%, £1,499 fee: £1,143.69 a month, £27,449 paid, £191,279 still owed, £1,499 fee. Total position: £220,226.

first direct fee-saver, 4.99%, no fee: £1,168.02 a month, £28,032 paid, £191,530 still owed, no fee. Total position: £219,562.

The fee-free deal wins by £664. Rates and fees: Moneyfacts, 5 August 2026. Payments calculated on a 25-year repayment term.

Note what the lower rate does buy you: £251 more capital paid off over the two years, because more of each payment goes to the balance rather than the interest. That's a genuine benefit and it's counted in the figures above. It just isn't anywhere near £1,499. So if you're borrowing around the £200,000 mark, the headline rate is pointing you at the wrong deal, and the gap is roughly a month's mortgage payment.

The £359,000 line

There's a loan size at which the arithmetic flips, and it's worth knowing where it sits, because it's a long way above what most first-time buyers borrow.

Run the same two-year comparison at different loan sizes and the fee-free deal keeps winning until the mortgage reaches roughly £359,000. At £250,000 the fee-free deal is £455 cheaper. At £300,000 it's £247 cheaper. At £340,000 it's £80 cheaper. Only above about £359,000 does the 4.78% rate finally earn back its £1,499.

For context, the average UK house price was £277,542 in July 2026 (Nationwide HPI, July 2026), and first-time buyers typically buy below the national average, not above it. A £359,000 mortgage at 90% LTV means a purchase price around £399,000. That isn't a first-time buyer number outside London and a handful of southern commuter towns.

The 95% LTV pair tells a subtler story. West Brom BS offers 5.15% with a £499 fee, and 5.27% with no fee and a free valuation, both in England and Wales (Moneyfacts, 5 August 2026). There the break-even loan is about £209,000, which is close enough to a typical first-time buyer mortgage that it's genuinely a coin flip: at £200,000 the fee-free version is £21 cheaper over two years, and at £250,000 the fee version is £98 cheaper. So the rule isn't "always avoid fees", it's "work out where your loan sits relative to the break-even", and for a 5% deposit buyer that line falls right through the middle of the market.

Adding the fee to your loan turns £1,499 into £2,571

Lenders will offer to add the product fee to the mortgage instead of taking it at completion, and it's an easy yes when you're already short of cash for stamp duty, searches and a survey. It's also the most expensive way to pay it.

A £1,499 fee added to a 25-year mortgage at 4.78% costs about £8.57 a month for the full term. Over 300 months that's roughly £2,571. You've borrowed for 25 years to buy a rate discount that lasts two, and paid an extra £1,072 for the privilege.

Worse, the fee is now inside your balance, so it nudges your loan to value upward at exactly the moment you're trying to push it down into a cheaper band. On a marginal case, £1,499 is enough to keep you at 90% rather than crossing into the 85% band at your next remortgage. So if you're within a few thousand pounds of an LTV threshold, paying any fee upfront is worth more than the interest saving alone suggests.

Why the tables keep pointing you at the wrong deal

Comparison tables sort by rate because rate is the one number every product has. Fees vary, incentives vary, cashback varies, and free valuations are worth up to £740 on some deals and nothing on others. Rate is the only field that sorts cleanly, so it's the field that sorts.

Fees have also been getting bigger and harder to avoid. Moneyfacts figures from March 2025 put the average product fee on a fixed rate deal, excluding no-fee products, at £1,129, and found that 36% of fixed deals came with no product fee, down from 41% in 2020. Choice overall is recovering: total product count rose from 7,132 in June 2026 to 7,177 in July 2026 (Moneyfacts UK Mortgage Trends Treasury Report, July 2026). More deals, more fee structures, more ways for a sorted-by-rate table to mislead you.

And the spread between what's advertised and what's typical is wide. The whole-market average two-year fix stood at 5.63% as at 7 August 2026 (Moneyfacts, reported by Mortgage Introducer), against best buys in the 4.3% to 5.3% range depending on your deposit. Bank Rate has been held at 3.75% since 30 July 2026, with the next Bank of England decision due 17 September 2026, so nothing about the base rate is going to rescue a badly chosen product in the meantime. If you're comparing deals this month, assume the table is optimised for the lender's marketing, not for your loan size.

The one calculation to run before you apply

It takes about ninety seconds and it works on any pair of deals.

Take the rate difference between the two products, in percentage points. Multiply it by your loan. Divide by 12. That's roughly what the lower rate saves you each month. Now divide the fee by that number. If the answer is more months than your fix lasts, the fee-free deal is cheaper.

On our two deals: 0.21% of £200,000 is £420 a year, or £35 a month at the start, falling as the balance drops. The precise figure is £24.33 because the saving applies to the interest portion rather than the whole payment, which is why it's worth checking with a proper amortisation rather than the rough version. Our mortgage calculator will give you both monthly payments in under a minute, and then it's simple subtraction.

Do the same thing on the reversion rate while you're there. Both deals here revert to 6.24% at the end of the fix (Moneyfacts, 5 August 2026), which is why the plan has to include remortgaging on time rather than drifting onto the follow-on rate. We've covered how to choose between a two and five-year fix separately, and the fee arithmetic changes with the length of the deal: a five-year fix gives a fee 60 months to pay for itself instead of 24, which is exactly why fees are more defensible on longer products.

So if you're weighing up two deals right now, run the total-cost sum on both before you let a broker or a table pick for you.

What this means for you

Frankly, if you're a first-time buyer borrowing under about £250,000, the maths points toward the fee-free deal almost every time at current pricing, and you should be actively asking for the fee-free version of anything you're quoted rather than waiting for it to be offered. Roughly one fixed deal in three has no product fee (Moneyfacts, March 2025), so they aren't hard to find, they're just harder to sort by.

Two exceptions are worth holding on to. If you're borrowing above roughly £359,000, the fee genuinely does pay for itself on this particular pair of products, and the same will be true of most high-fee, low-rate deals at that scale. And if you're taking a five-year fix rather than a two, the fee has more than twice as long to earn out, so re-run the sum rather than assuming the answer carries over.

Everything else is the same discipline: total cost over the fixed period, including the fee, including the balance you'll still owe at the end. That's the number that decides what you actually pay. The rate is just the part the marketing department chose to put in large type. And if your deposit is the thing standing between you and a better band altogether, our piece on what a 5% deposit really costs is the next thing to read, because moving from 95% to 90% LTV is worth far more than any fee decision on this page.
