Is Buy-to-Let Still Worth It in 2026? The Reality for UK Landlords
Buy-to-let has traditionally been one of the most popular routes into property investment, giving landlords the opportunity to generate rental income while holding an asset with long-term growth potential. In 2026 however, the landscape looks very different.
Interest rates are higher than the ultra-low levels many landlords had grown used to, tax relief on mortgage interest has been restricted to the basic rate since 2020, and the Renters’ Rights Act have all brought significant upheaval to the private rental sector. A further increase in the tax rate applied to property income is due from April 2027, adding to the cost pressures on landlords managing properties in personal names. Against that backdrop, many existing and prospective landlords are asking the same question: is buy-to-let still worth it?
For many investors, buy-to-let can still work well but it now requires far more careful planning than it perhaps did. It has become a more specialist market, although not necessarily a less attractive one for landlords who are properly advised and realistic about the returns they are likely to achieve.
The landlords who are likely to succeed are those who understand their numbers before they commit, rather than relying on historic assumptions about rental growth or treating the new rules as something to think about later.
Rental demand remains strong, but affordability matters
Strong demand for rental homes remains a major advantage, particularly in areas where supply is limited and would-be homeowners are staying in the rental market for longer. According to ONS data, average UK monthly private rents reached £1,367 in January 2026, up 3.5% year-on-year, with the North East recording the strongest regional growth at 8.0%. On the surface, this sustained demand is positive news for landlords, as higher rents generate a stronger income and help protect against rising costs. However, landlords should be careful not to assume that rents can keep rising at the same pace, even in the shorter term.
Tenant affordability
Tenant affordability is now a very real constraint in many areas, and in some markets rent growth has slowed significantly as tenants reach the limit of what they can comfortably pay. Zoopla’s June 2026 rental market report notes that annual rental growth currently varies from just 0.4% in the West Midlands to 3.8% in the North East, while average earnings are growing at around 4% — meaning wages are now outpacing rent rises in many areas for the first time in years. This means landlords need to consider whether the property is likely to remain affordable for the type of tenant it is aimed at, particularly given that rent increases are now capped to once per year under the Renters’ Rights Act.
A property that looks strong on paper because the rent is high may still carry risk if that rent sits at the very top end of the market, which is why the more sustainable buy-to-let investments are often those where the rent feels realistic and there is enough margin left after mortgage payments and running costs.
Yields are only part of the picture
Gross yield remains one of the first calculations most landlords consider, as it shows the annual rent as a percentage of the purchase price and can be useful when comparing different areas. While gross yield is a useful starting point, a landlord also needs to account for mortgage interest, service charges, maintenance costs, insurance, agent fees, void periods and tax, as the net yield can look very different once those costs are included.
This is particularly important in higher-value markets where purchase prices are high and yields tend to be lower. A property in London or the South East may appear to offer stronger long-term capital growth potential, but the monthly cash flow can be tighter, especially with today’s borrowing costs.
Some regional markets can offer higher yields, although landlords still need to consider tenant demand and resale potential before assuming the better yield automatically means the better investment.
How do you calculate if a buy-to-let is worth it?
Beyond yield, landlords should also assess their return on capital invested — a metric that gives a clearer picture of whether a deal is actually working for them. This calculation compares the net annual profit against the cash actually deployed into the deal, rather than the total property value. For a leveraged buy-to-let purchase with a 25% deposit and mortgage in place, net returns on capital invested of 8% to 14% are broadly considered strong in the current market, and well ahead of what a landlord would achieve holding the same capital in a savings account or many other asset classes. A net return on capital below 5% after all costs — including mortgage interest, management fees, insurance, maintenance and voids — warrants careful scrutiny, particularly where the landlord is carrying risk in a higher-rate environment.
Capital Growth
It is also worth remembering that buy-to-let returns are not income alone. Capital growth forms a significant part of the overall investment case, and UK house prices have historically delivered long-term appreciation that other asset classes rarely match consistently. Average UK house prices have risen by around 38% to 50% across England since 2015, with some Northern cities such as Manchester and Salford seeing rises approaching or exceeding 60% over the same period, according to Land Registry data. The average UK house price stood at approximately £270,000 at the end of 2025 according to ONS figures. While economic conditions, interest rates and regional supply dynamics all influence the pace of capital growth, Savills forecasts cumulative UK house price growth of around 22% over the five years to 2030, with Northern England, Wales and Scotland expected to lead performance, projecting 20–25% growth over the same period. In areas of active regeneration, near infrastructure investment or benefiting from demand for rental accommodation, capital growth can be meaningfully ahead of the national average. When income and capital appreciation are combined, the total return case for well-selected buy-to-let property remains compelling — provided the deal stacks up on both measures from day one.
Lending can make or break the deal
Buy-to-let lending is not just a matter of finding the lowest headline rate. Lenders assess affordability by looking at whether the expected rent is enough to cover the mortgage interest at a stressed rate, as well as considering the borrower’s product type and ownership structure.
For many landlords, this is where the deal either works or falls down; a property may appear profitable at the actual mortgage rate, but it may not pass a lender’s stress test, which can restrict borrowing or change which lender is suitable. In practice, most mainstream lenders currently stress test at 5.5% (or the product rate plus 2%, whichever is higher) and require the rent to cover 125% of that stressed interest for basic-rate taxpayers, or 145% for higher-rate taxpayers — a threshold that has caught many landlords out in the current rate environment. This is one of the reasons advice early in the process has become so important. A high rent does not automatically mean a landlord will be able to borrow more, because lenders are looking at whether the rental income remains strong enough under their specific affordability model.
Most buy-to-let investors should also expect to need a sizeable deposit. While criteria vary, many lenders typically want around 25%, with some specialist options available depending on the borrower and the wider portfolio.
Is it worth setting up a limited company for buy-to-let
Landlords should understand how much they can borrow, how the rental income will be assessed and whether the application would be stronger in their personal name or through a limited company. The right answer will depend on the landlord’s circumstances, which is why mortgage advice should sit alongside tax advice before any decisions are made.
What the new Renters’ Rights rules mean for buy-to-let returns
The Renters’ Rights Act does not mean buy-to-let is no longer viable, but it does change how landlords need to assess risk before buying or refinancing.
As of 1st May 2026, Section 21 “no fault” evictions can no longer be used for existing or new tenancies in England. Assured shorthold tenancies have also been replaced by assured periodic tenancies, meaning landlords have less flexibility to rely on fixed rental terms and must follow the correct legal route if they need to regain possession of a property.
For investors, this means the exit strategy needs careful thought. A landlord who may want to sell in the short to medium term will need to understand the notice periods involved and how this could affect the timing of a sale. This does not prevent landlords from selling, but it does mean they should build more time into their plans.
The new rules also affect income planning. Landlords can only increase rent once per year, must give at least two months’ notice and must use the formal Section 13 process, making it even more important to set a realistic rent from the outset and ensure the mortgage remains affordable if costs rise before the next rent review can take place.
In practical terms, the Act makes buy-to-let less forgiving for landlords who are relying on short-term flexibility or aggressive rent increases. However, for investors who are comfortable holding the property over the longer term and are working with realistic rental assumptions, buy-to-let can still remain a viable investment.
This is also relevant from a lending perspective, because brokers and lenders are looking more closely at the overall strength of a buy-to-let case. The headline rent is still important, but so is the landlord’s ability to absorb higher costs and hold the property if the market does not move as expected.
So, is buy-to-let still worth it?
Buy-to-let is no longer the easy win it may once have appeared to be. Higher borrowing costs, tighter affordability testing and new rental rules mean landlords have to work harder to make the numbers add up, although that does not mean the opportunity has disappeared.
The data supports the view that buy-to-let retains a strong long-term investment case. Gross yields across the UK currently sit between 5% and 8%, with net yields typically in the 4% to 6% range depending on location and cost structure. When capital growth is factored in alongside income, total returns of 8% to 12% per annum are achievable for investors who have chosen the right property in the right location with the right financing. Hamptons forecasts that rents across Great Britain will rise by 17% between 2024 and 2027, outpacing house price growth over the same period — a meaningful tailwind for income-focused landlords. In the near term, rental growth has moderated from the sharp spikes of 2022 and 2023, with Rightmove forecasting around 2% growth in advertised rents for 2026. However, the structural imbalance between supply and demand is not going away. Cushman & Wakefield’s 2026 residential forecast notes that the shortage of rental homes is unlikely to improve in the short to medium term, as regulatory pressures continue to reduce the supply of private rented properties. With the average UK house price now sitting at eight to nine times average earnings, millions of would-be homeowners remain locked out of ownership and dependent on the private rented sector — supporting rental demand for the foreseeable future.
Looking at the broader BTL mortgage market, the outlook is improving. The Intermediary Mortgage Lenders Association (IMLA) forecasts that gross buy-to-let lending will rise from an estimated £39bn in 2025 to £44bn in 2026 and £48bn in 2027, as rising rental yields and market churn driven by the Renters’ Rights Act increase activity. BTL house purchase lending alone is projected to grow to £14bn by 2027, driven in part by more professional landlords entering the market as less prepared operators exit. On mortgage rates, geopolitical uncertainty has introduced some short-term volatility, but the general direction of travel remains downward. Experts continue to expect further Bank of England base rate reductions over the medium term, which will feed through to improved affordability on BTL lending over time. For landlords who can lock in a competitive rate now and plan for the medium term, the financing environment is more manageable than it may appear at first glance.
What all of this points to is that the medium to long-term rental market remains fundamentally well-supported, even if the next twelve months require patience and careful management. Investors who go in with the right strategy — realistic rents, a robust financing structure, and a clear view of their numbers — are well placed to benefit from both the income generated today and the capital growth that the market is forecast to deliver over the next five years. The landlords most likely to succeed are those who take professional advice early, understand their options thoroughly and ensure their mortgage structure is working as hard as their asset.
For some, the answer may be to pause or refinance before making another move, while for others it may be to expand carefully as less prepared landlords leave the market. Landlords need to ask whether a specific property, in a specific location, with the right finance structure, is worth it for their circumstances.
That is where professional advice can make a significant difference. Buy-to-let still has a place, but landlords need to go into it with their eyes open, with the focus on cash flow and lender criteria.
