Fleet’s 3.49% Buy-to-Let Fix: The Cost Beyond the Rate
Market Intelligence · 20 October 2026

Fleet Adds a Shorter Fix for Landlords

The new range expands refinancing choices. Fees and actual exit dates determine how well it fits the next stage of a property investment.

Fleet Launches 3.49% Buy-to-Let Fix With a £10,000 Product Fee on a £400,000 Loan

New shorter-term products give professional landlords another option beyond longer fixes. Their value depends on the cost of entering, the date of leaving and what happens to the debt afterwards.

Fleet Mortgages has introduced a range of one-year fixed-rate buy-to-let products starting at 3.49%, expanding the choices available to landlords reluctant to commit to a longer fix. But the accompanying 2.5% product fee makes the total cost particularly important: on a £400,000 loan, that fee alone is £10,000.

The range covers standard buy-to-let, limited company borrowing, houses in multiple occupation and multi-unit freehold blocks. Its arrival gives professional investors another way to match borrowing to a planned sale, refinancing or period of portfolio consolidation.

That is a useful development. A landlord expecting to hold a property for decades and one considering a sale in the next two years may reasonably want different mortgage arrangements, even when their properties and borrowing requirements look similar.

The question is whether the new option fits the investor’s timetable at an acceptable overall cost. A lower initial rate can improve monthly cash flow while still requiring a substantial financial commitment upfront.

What Fleet Has Introduced

The new standard and limited company products are priced at 3.49%, while the HMO and MUFB option starts at 3.74%. All three are available up to 75% loan to value and carry a 2.5% product fee.

New shorter fixed-rate products reviewed on 20 October 2026. Subject to availability, eligibility and the individual mortgage offer.
Borrowing category Initial rate Maximum LTV Product fee
Standard buy-to-let 3.49% 75% 2.5%
Limited company buy-to-let 3.49% 75% 2.5%
HMO / MUFB 3.74% 75% 2.5%

Fleet also reduced its standard two-year HMO/MUFB fixed rate from 5.19% to 4.89%, with a 3% fee. That creates a further comparison for landlords weighing a shorter commitment against a longer period of payment certainty.

The launch was reported by The Intermediary on 19 October. Fleet’s product guide is dated 16 October, while its announcement page contains a separate reference to 17 October. It is therefore more accurate to describe this as a recently introduced range than to assume it first became available yesterday.

“One Year” Does Not Mean Twelve Months From Completion

The product guide gives the new range a fixed-rate end date of 31 March 2028, with a 3% early repayment charge running to that date.

That detail changes the analysis. A landlord completing on 1 November 2026 would have approximately seventeen months until the published end date. Someone completing later would have a shorter period.

The product name therefore cannot substitute for a calendar. A client planning to sell in autumn 2027 could still be within the early repayment charge period, despite having chosen a product described as a one-year fix.

The Relevant Date Is the Contractual End Date

For a landlord planning a disposal or refinancing, the mortgage offer’s fixed-rate and early repayment charge dates should be compared directly with the intended transaction date.

A shorter product can provide useful flexibility, but only if that flexibility becomes available when the borrower needs it.

The £400,000 Example Shows Why Fees Matter

Assume a £400,000 interest-only mortgage at 3.49%, with the £10,000 product fee paid separately. Annual interest would be £13,960, or approximately £1,163.33 a month.

Over an illustrative seventeen-month period, interest would total approximately £19,776.67. Adding the product fee produces a combined interest-and-product-fee cost of approximately £29,776.67.

Illustration only: constant £400,000 interest-only balance, 3.49% throughout, seventeen months calculated as 17/12 of a year, and the product fee paid upfront.
Measure Illustrative amount
Monthly interest £1,163.33
Interest over seventeen months £19,776.67
2.5% product fee £10,000
Interest plus product fee £29,776.67
Mortgage capital still outstanding £400,000

This is not an APRC calculation or a full mortgage quotation. It excludes legal, valuation, broker, administration and exit costs, any incentives, and the cost of the next financing arrangement. Actual interest depends on completion dates and the lender’s calculation method.

It does, however, show why the monthly payment is only part of the decision. Paying a fee separately makes it less visible in the mortgage payment; it does not make it disappear from the investment’s costs.

If a product fee can be added to the borrowing, that also needs to be modelled explicitly. The borrower then owes more and may pay interest on the fee. The treatment must be checked against the lender’s terms and borrowing limits.

A Higher Rate Can Still Deserve Consideration

For comparison, consider a purely hypothetical alternative charging 4.49% with a £2,000 fee over the same seventeen-month assessment period.

On the same £400,000 interest-only balance, interest would be approximately £25,443.33. Including the fee gives £27,443.33, around £2,333 less than the first illustration despite the higher rate.

This is not an available product or a recommendation. It isolates the effect of the fee, assuming everything else relevant is equal. In practice, exit charges, incentives, eligibility and the duration of the rate would also need to match.

The comparison explains why a rate table cannot settle the question. A landlord with a larger loan or a longer holding period may reach a different conclusion because the interest saving has more time, or a larger balance, over which to offset the fee.

Shorter Fixes Bring the Next Decision Closer

A shorter fixed period may appeal to landlords who want another opportunity to review their borrowing sooner. That opportunity has value, but it is not a guarantee that the next mortgage will be cheaper.

Future pricing, property values and lender criteria are unknown. The borrower’s circumstances may also change: a tenancy could end, an expense could rise or the portfolio could become harder to refinance on the intended terms.

Two financing decisions therefore sit inside the current choice. The first is whether the new mortgage works until its fixed period ends. The second is whether the investment remains sustainable if the next arrangement costs more than hoped.

Fleet’s current product listing shows a variable reversion rate linked to Bank Rate plus three percentage points. The future payable rate will depend on Bank Rate at that time; today’s figure should not be treated as a forecast.

A landlord comparing a shorter fix with a longer one should use a common investment horizon. Comparing only the first product’s introductory period with several years of another product leaves the future refinancing cost out of one side of the calculation.

The Exit Charge Can Outweigh a Rate Saving

A 3% charge applied to a £400,000 outstanding balance would be £12,000. The actual charge depends on the mortgage terms, the balance and any applicable allowances, but the scale is clear.

For an investor expecting to sell, an earlier-than-planned transaction could therefore create a material cost. A later-than-planned sale could instead leave the borrower needing temporary continued finance after the initial rate ends.

The appropriate product should be assessed against both possibilities. An expected sale date is rarely certain enough to justify ignoring what happens on either side of it.

This does not make a shorter fix unsuitable for a planned disposal. It means the expected saving should be assessed alongside the financial consequences of the sale moving forward or slipping back.

A Lower Payment Rate Does Not Automatically Mean a Larger Loan

The rental assessment also deserves attention. Fleet’s published limited company product uses rental coverage of 125% at a 5.50% assessment rate, rather than assessing the loan solely at the 3.49% initial payment rate.

On a simplified £400,000 calculation, that produces a rental requirement of approximately £27,500 a year, or £2,291.67 a month, before other criteria are considered.

That is distinct from the mortgage interest actually payable during the introductory period. The first figure is part of an underwriting test; the second describes a financing expense.

For landlords reviewing an earlier unsuccessful enquiry, this distinction matters. A more attractive monthly payment does not by itself establish that the property now supports the required borrowing.

The Portfolio May Need Several Different Timetables

For a professional landlord, the best answer may differ from one property to another. A long-term holding with dependable rent may justify a different commitment from a property earmarked for sale.

There is also the timing of the portfolio’s debt as a whole. If several large mortgages expire together, the landlord faces a concentrated period of refinancing work and exposure to whatever lending conditions exist then.

Staggering expiry dates can spread that exposure. It can also increase the frequency of reviews and transaction costs, so it should have a clear purpose rather than become a rule applied to every portfolio.

A useful review brings together outstanding balances, rents, current product end dates, early repayment charges and the intended future of each property. Those facts reveal whether a shorter mortgage solves a specific problem or simply postpones the next decision.

Fleet’s new range adds a useful option for that discussion. The commercial value lies in matching borrowing to the landlord’s plans and comparing the full cost of doing so. A 3.49% headline earns attention; the fee, expiry date and next refinancing decision determine whether it earns a place in the portfolio.

Frequently Asked Questions

Shorter fixed-rate mortgages, product fees and portfolio refinancing.

Does Fleet’s one-year fix last exactly twelve months?

The published products have a fixed-rate end date of 31 March 2028. The actual period depends on completion, so borrowers should use the dates in their mortgage offer rather than assume twelve months.

What is the product fee on a £400,000 mortgage?

A 2.5% product fee on £400,000 is £10,000. This is additional to interest and other applicable costs. If a fee is added to borrowing, the resulting balance and interest must also be considered.

Can a landlord leave the mortgage early without a charge?

The new range carries a 3% early repayment charge during the published fixed period. Check the mortgage offer, including any allowances and the amount to which the charge applies.

Does the lower initial rate guarantee more borrowing?

No. Rental coverage, the lender’s assessment rate, valuation and other underwriting requirements determine available borrowing. The payment rate alone does not establish eligibility.

Should every property in a portfolio use the same mortgage term?

Not necessarily. The appropriate term depends on each property’s intended holding period and the portfolio’s cash flow. Staggering expiry dates can spread refinancing exposure, but may add administration and costs.

Product details reflect the sources reviewed on publication. Rates, fees, incentives, availability and lending criteria can change. The individual mortgage offer determines the applicable conditions and dates.

The cost illustrations assume a constant £400,000 interest-only balance, fees paid separately and a seventeen-month period calculated as 17/12 of a year. They exclude other charges, incentives, tax effects and subsequent borrowing costs. They are not APRC calculations or complete mortgage quotations.

The 4.49% rate with a £2,000 fee is a hypothetical comparison, not an advertised or available product. The £12,000 early repayment charge illustration assumes a 3% charge applies to a £400,000 balance.

The rental calculation is a simplified illustration of one published assessment. It does not establish the maximum loan available or confirm eligibility.

Interest-only mortgage payments do not repay the capital. Future refinancing, property values, rental income and mortgage rates are not guaranteed.

Your property may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.
