What changed for UK landlords in 2025 and 2026?
Three structural shifts landed on UK landlords within twelve months, and 2026 is the first full year all of them bite. Each shift changes running costs, so the buy-to-let (BTL) maths of 2020 no longer describes 2026.
Regarding regulation, the Renters' Rights Act 2025 took effect on 1 May 2026. Section 21 "no-fault" evictions are abolished, fixed terms are replaced by periodic tenancies, and rent rises are limited to once per year via a Section 13 notice with two months' notice. Tenants can challenge any increase at a First-tier Tribunal for a £47 fee (NRLA) — and early tribunals have cut proposed rents, not just trimmed them.
Regarding energy standards, the government confirmed on 21 January 2026 that private rented homes in England and Wales must reach EPC C by October 2030. Upgrades lagging behind the band face spending on insulation, heating, or glazing within four years.
Regarding financing, borrowing costs stay high. The average two-year fixed BTL mortgage rate hit 5.44% in April 2026 (Moneyfacts), with the Bank of England base rate at 3.75%. Cheap-money buy-to-let is over — these changes are law and rates, not proposals.

What do buy-to-let returns actually look like after costs?
Gross yields of 6.93% look healthy, but a realistic £270,000 example nets roughly 4-5% on cash before tax and capital growth. When it comes to returns, the gross-to-net spread does the damage.
Paragon Bank's Q4 2025 Buy-to-Let Yield Report puts the average UK gross yield at 6.93%, with houses in multiple occupation (HMOs) at 8.61%. The average buy-to-let home costs £270,045 (Guild of Residential Landlords), and ONS data shows the average UK rent at £1,366 per month. Rent growth, however, is cooling: ONS annual growth slowed from 6.7% (June 2025) to 4.4% (November 2025).
The worked example — a £270,000 property at the 6.93% average gross yield, 25% deposit, interest-only mortgage at 5.44%:
| Item | Annual Figure |
|---|---|
| Rent (£270,000 × 6.93%) | £18,711 |
| Rent after 4% void allowance | £17,963 |
| Mortgage interest (£202,500 × 5.44%) | −£11,016 |
| Repairs & maintenance (~8% of rent) | −£1,437 |
| Management or admin (~10% of rent) | −£1,796 |
| Insurance & compliance costs | −£600 |
| Pre-tax profit | ≈ £3,114 |

Section 24 caps mortgage-interest relief at a 20% tax credit, so a higher-rate taxpayer keeps less still. Savills revised its 2026 forecast in June 2026 to −2% for mainstream house prices. The bottom line: the example returns about 4.6% on £67,500 cash invested, before tax and capital growth — rent growth, not house prices, now drives returns.
Which landlords are still making money?
Landlords buying below market value, adding value before letting, or running HMOs still clear their hurdle rates. On the question of who profits, the divide is business discipline, not luck.
Paragon's yield data shows HMOs returning 8.61% gross — well above the 5.44% cost of a two-year fixed mortgage. Landlords who buy at 15-20% below market value, or who refurbish and force appreciation, manufacture a yield buffer the average buyer lacks. Guild of Residential Landlords data confirms northern markets around £170,000 yield far more than southern price hotspots.
By contrast, Hamptons estimates around 93,000 landlords — roughly 6% of BTL mortgage holders — exited in 2025, and about 850,000 homes have left the private rented sector over the past decade. Smaller-deposit, peak-price amateurs absorbed the worst of Section 24 and the rate reset. Paradoxically, The Negotiator reports rental supply hitting a seven-year high in 2026, so departing landlords are not creating scarcity pricing. The gap between the best and worst operators is widening — management quality now shows up directly in returns.

Should you sell, hold, or buy in 2026?
Hold if your net yield beats your mortgage rate and you can fund EPC C work; sell if repairs plus compliance would exceed 12 months of profit; buy only where gross yield minus 30% cost loading beats 4% on cash.
Regarding holding, Hamptons notes landlord sales slowed after the Renters' Rights Act began — the panic-exit phase has passed. If your property yields 7%+ gross with a fixed mortgage below 5.5%, holding through the 4.4% rent-growth environment is rational.
Regarding selling, capital gains tax runs at 18%/24% on residential gains, so model the exit before the October 2030 EPC C deadline compresses the buyer pool for inefficient stock. The −2% Savills price forecast means waiting costs little — but doing nothing still has a price.
Regarding buying, ~850,000 homes left the sector in a decade, yet supply sits at a seven-year high (The Negotiator). That balance argues for patience: buy only where the numbers work on day one, not on hoped-for rent rises.

So, is buy-to-let still worth it in 2026?
Buy-to-let in 2026 is worth it as a business, not a passive pension. The 6.93% average gross yield (Paragon) is real, and so is the 5.44% mortgage rate (Moneyfacts) — the difference is where the work happens.
Buy-to-let rewards three behaviours in 2026:
- Yield discipline: buy only where gross yield exceeds the mortgage rate by 1.5 percentage points or more.
- Compliance readiness: budget for EPC C before October 2030 and operate within Section 13 rent-rise rules.
- Long horizon: with prices forecast −2% (Savills) and rent growth at 4.4% (ONS), income carries the return.
Buy-to-let in 2026 rewards operators and punishes bystanders — that is the honest breakdown.
