The Bank of England has held the Base Rate at 3.75% for three consecutive meetings. For the first time in two years, the conversation among buy-to-let landlords isn’t about how high rates will go, but when they will start to fall — and what that means for the £300 billion of BTL mortgages due to mature over the next eighteen months.
At Anteire, we speak to portfolio landlords every week who are weighing up the same dilemma: fix now and lock in a rate around 4.5–5.5%, or wait in the hope that a Bank Rate cut in late 2026 or early 2027 will deliver something closer to 4.0%. The difference between those two decisions can be 0.8% or more on a five-year fix — a meaningful sum when applied to a leveraged portfolio.
This post sets out the data, the trade-offs, and a practical framework for making the call. We’ll look at where BTL mortgage rates are today, what the forward curves and rental market data tell us, and how a handful of landlords are saving 0.8% by improving their loan-to-value (LTV) band or restructuring their borrowing.
Where BTL mortgage rates sit in mid‑2026
The table below summarises the typical rates we’re seeing across the market for standard buy-to-let remortgages (property value £200,000–£500,000, loan £100,000–£375,000, interest-only, arranged via a limited company or personal name). All figures are illustrative and based on broker and lender data as of early July 2026.
| Product | Typical rate (range) | Arrangement fee | Notes |
|---|---|---|---|
| 2‑year fixed (60% LTV) | 4.50% – 4.80% | 1.0% – 1.5% | Most popular product; rate depends on rental cover and borrower profile. |
| 2‑year fixed (75% LTV) | 4.90% – 5.30% | 1.0% – 1.5% | Wider spread reflects higher risk weighting. |
| 5‑year fixed (60% LTV) | 4.40% – 4.70% | 1.0% – 1.5% | Slightly cheaper than 2‑year fixes; offers payment certainty. |
| 5‑year fixed (75% LTV) | 4.80% – 5.20% | 1.0% – 1.5% | Rate premium over 60% LTV typically 0.3–0.5%. |
| Tracker (lifetime, 60% LTV) | Bank Rate + 0.80% – 1.00% | 0.5% – 1.0% | Currently 4.55% – 4.75% pay rate; moves with Base Rate. |
| Standard variable rate (SVR) | 7.50% – 8.50% | None | Avoid unless bridging very short term. |

The 0.8% saving we reference in the title is the gap between a landlord who refinances today onto a 75% LTV 5‑year fix at 5.20% and one who waits a few months, improves their LTV to 60% (perhaps by injecting a small amount of equity or benefiting from modest capital growth), and secures a 4.40% rate. That 0.8% reduction on a £200,000 interest‑only loan saves £1,600 per year — or £8,000 over a five‑year term — without taking on additional risk.
The case for fixing now
1. Certainty in a still‑uncertain inflation environment
Although CPI inflation has fallen back to 2.4%, services inflation remains sticky at 4.1% (ONS, May 2026). The Monetary Policy Committee has signalled it wants to see services inflation below 3.5% before cutting rates. If that takes longer than markets expect, fixed rates could stay elevated for another 12 months. Locking in a 5‑year fix at 4.50% today removes that uncertainty.
2. Rental cover calculations are tightening
Lenders typically require rental income to cover 125%–145% of the mortgage payment at a notional stressed rate (often the higher of pay rate + 1% or a 5.5% floor). With average UK rents rising 4.2% year‑on‑year (HomeLet Rental Index, June 2026), many landlords who were borderline on rental cover a year ago now qualify comfortably. Fixing now locks in that improved affordability before any softening in rental growth — which Savills forecasts will slow to 2.5% per annum by 2027 — erodes the buffer.
3. Product availability is good, but not guaranteed
Lender appetite for BTL remains healthy, but the market is sensitive to regulatory shifts. The Prudential Regulation Authority’s consultation on tighter portfolio landlord underwriting standards is expected to conclude in Q4 2026. If implemented, it could reduce the number of lenders willing to offer high‑LTV products or interest‑only terms. Acting before any rule changes gives you a wider choice of products.
The case for waiting
1. The forward curve points to lower rates
As of 7 July 2026, SONIA swap rates imply a Bank Rate of 3.25% by mid‑2027 and 2.75% by mid‑2028. If those expectations materialise, a landlord who waits 12 months could refinance onto a 5‑year fix around 3.80%–4.20% — a saving of 0.5%–0.8% compared with today’s best 5‑year fixes. For a portfolio of five properties, that’s a potential annual saving of £5,000–£8,000.
2. Capital values are stabilising, which helps LTVs
After a 4.7% peak‑to‑trough decline in UK house prices (Zoopla House Price Index, May 2026), values have been edging up 0.2%–0.3% per month since January. JLL forecasts cumulative UK house price growth of 8.2% between 2026 and 2029. If your property is currently at 72% LTV, six months of modest growth could push it below 70%, opening up a cheaper rate band. Waiting for that natural deleveraging can be more cost‑effective than injecting fresh equity.
3. Early repayment charges may outweigh the benefit of switching now
Many landlords coming to the end of a 5‑year fix taken out in 2021 still face ERCs of 1%–3% if they refinance more than three months early. If your current pay rate is 3.0%–3.5% and you have six months remaining, it often makes sense to sit tight, absorb the slightly higher SVR for a month or two, and then refinance when the ERC window closes. The maths is straightforward: paying 7.5% SVR for two months costs roughly 1.25% of the loan balance in interest, which is often less than a 2% ERC.
How to save 0.8% — a practical checklist
The landlords we work with who consistently secure the sharpest rates don’t just time the market; they improve their risk profile before approaching a lender. Here are the levers that typically deliver a 0.5%–0.8% reduction.
1. Move down an LTV band
The biggest rate jumps occur at 75% and 80% LTV. If you’re at 76% LTV, a 1% capital injection (or a favourable desktop valuation) can drop you into the 75% band and save 0.3%–0.5%. If you’re at 61% LTV, pushing to 60% can unlock a further 0.2%–0.3% saving. We’ve seen landlords achieve this by:
– Using retained rental profits to make a small overpayment.
– Requesting an updated valuation from the lender (often free).
– Restructuring cross‑collateralised portfolios to release equity in one property and reduce LTV on another.
2. Improve your rental cover ratio
Lenders price risk based on the gap between actual rent and the stressed rental cover requirement. If your rent has risen 5% since you last fixed but your lender’s calculation uses an outdated figure, you may be paying a higher rate than necessary. Provide a current tenancy agreement and three months’ bank statements showing the new rent. In some cases, this alone can move you from a “standard” to a “core” product range, saving 0.2%–0.4%.
3. Use a specialist BTL broker with whole‑of‑market access
Not all lenders publish their best rates on comparison sites. Several building societies and niche lenders offer “portfolio” products with lower stressed rates or more generous interest cover ratio (ICR) calculations for experienced landlords. A broker who understands your wider portfolio can often find a rate 0.3%–0.5% below the high‑street headline. At Anteire, we regularly see landlords save 0.8% or more simply by moving from a high‑street lender to a specialist that better matches their profile.
4. Consider a limited company remortgage
With Section 24 fully phased in, higher‑rate taxpayers holding property in their personal name are seeing effective tax rates of 40%–45% on rental income before mortgage interest relief. Remortgaging into a limited company structure can reduce the overall cost of borrowing by 0.5%–1.0% on an after‑tax basis, even if the headline rate is similar. This is a complex area requiring tax advice, but it’s one of the most powerful tools for improving net returns.

What the data says about rental demand and void risk
Refinancing decisions shouldn’t be made in isolation from the rental market. The latest HomeLet data shows:
- UK average rent: £1,279 per calendar month (June 2026), up 4.2% year‑on‑year.
- London average rent: £2,103, up 3.8%.
- Void periods nationally: 2.1 weeks (Zoopla, Q1 2026), down from 2.4 weeks a year earlier.
JLL’s mid‑2026 forecast expects rental growth to average 3.5% per annum over the next five years, supported by constrained housing supply and steady demand from households unable to access owner‑occupation. This environment is broadly supportive of BTL refinancing, as rising rents improve ICRs and give lenders confidence to offer keener rates.
However, Savills cautions that rental growth will diverge significantly by region. The North West and West Midlands are forecast to see 4.5%–5.0% annual rental growth through 2028, while London and the South East may slow to 2.0%–2.5%. Landlords with properties in higher‑growth regions may find waiting improves their LTV and rental cover sufficiently to justify a short delay.
A practical framework for deciding
We suggest landlords ask themselves three questions before locking in a new rate:
-
What is my current LTV, and can I realistically move into a cheaper band within six months? If you’re within 2% of a band threshold and expect capital growth or can make a small overpayment, waiting may pay off.
-
What is the shape of my portfolio’s rental cover? If your rent has risen strongly and you haven’t re‑submitted evidence to a lender, you may already qualify for a better rate. Get a current rent assessment before you refinance.
-
What is the cost of doing nothing? If you’re on a reversion rate of 7.5%+, every month of delay costs roughly 0.6% of the loan balance in extra interest. That quickly eats into any saving from waiting for a rate cut.
For most landlords we work with, the optimal path in mid‑2026 is a 5‑year fix at 60%–65% LTV, secured after a thorough review of the property’s current valuation and rental income. This locks in a rate in the mid‑4% range, provides long‑term certainty, and avoids the risk of being caught by regulatory tightening later in the year.
