    The 5-year fix is the workhorse of the BTL remortgage market, and the ICR mechanics at remortgage are the main reason. Where shorter fixes are stress-tested at a notional rate above the pay rate, most lenders assess a 5-year fix at or near the actual rate you’ll pay. When you’re remortgaging a loan you originally borrowed at lower rates, that distinction can be the difference between the numbers working and not — particularly on properties in lower-yield areas where rental cover was always tight.

    Five years also reduces the frequency of the re-test itself: you face the ICR calculation once now rather than twice over the same period. That matters for landlords who’ve had a change in personal tax position — higher-rate taxpayer status, for instance, pushes the required ICR to 145% on most lenders’ stress test, and avoiding that reassessment for half a decade has real value. The fee landscape on 5-year BTL fixes tends to carry percentage rather than flat fees; the tables show the true cost alongside every deal.

    We ingest the data ourselves

    Most comparison tables license the same third-party panel. We build ours directly from lender product data, run through our own quality-assurance pipeline — so we sometimes list deals other sites miss.

    Refreshed every night

    Every product, every lender, re-ranked nightly. No manually maintained best-buy lists, no stale screenshots of last week's market.

    We're the UK's only mortgage-only comparison site. No credit cards, no car insurance — just every flavour of mortgage, done properly.

    Frequently asked questions

    How these tables work, and how to choose between the deals on them.

    01How does the 5-year fix stress test help at remortgage compared with shorter terms?
    When you remortgage onto a 5-year fix, most lenders stress the ICR calculation at or near the pay rate — not at a loaded rate. If you’re rolling over a loan you first took out years ago, this can preserve the maximum loan available even if market stress rates have risen since origination. On a 2 or 3-year fix, the same rent and loan size would face a higher notional rate, potentially reducing how much equity you can carry or release.
    02Can I use a 5-year BTL remortgage to release equity for a further purchase?
    Yes, and this is the classic mechanism for portfolio growth — remortgaging an existing property to release equity, then using that as the deposit on the next acquisition. The equity release is tested under the ICR stress rules (at or near pay rate for a 5-year fix), and the blended LTV must still sit within the lender’s criteria. Percentage fees are common on the lowest 5-year BTL rates, so factor those into the equity release calculation — 2–3% on a large loan is meaningful.
    03Should I remortgage onto a 5-year fix or take a product transfer?
    A product transfer avoids a fresh ICR assessment — the lender simply offers you a new deal without re-underwriting. That’s valuable if your situation has changed since origination (different tax band, additional portfolio borrowing, lower rental income). The trade-off is that you stay with one lender’s pricing and cannot increase borrowing. If you want equity release, or if better rates are available elsewhere in the market, a full remortgage is worth the extra process.
    04What LTV tiers matter most for 5-year BTL remortgage rates?
    The meaningful pricing steps in the BTL remortgage market tend to fall at 60% and 75% LTV. The keenest rates sit at 60% LTV and below; a step up occurs at 65–75% LTV, and rates rise again above 75%. If your property has appreciated since your original purchase, recalculating your current LTV is worth doing — you may have drifted into a lower band that opens better pricing without needing to repay any capital.
