This is not the "should I buy a buy-to-let" question — that is a purchase decision. This is the quieter one that more landlords are actually asking in 2026: I already have a rental. Is it still worth keeping? Between Section 24, the Renters’ Rights Act and the day-to-day of running a let, plenty of people are weighing whether to hold, sell, hand it to an agent, or just run it better. Here is an honest look, without either the doom or the hype.
This is a general discussion, not financial or tax advice. Your own numbers and circumstances decide it — take advice before you sell or restructure.
The income is thinner than the rent suggests
The headline rent is never the number that matters. What is left after the real costs is, and in 2026 those costs bite harder:
None of that means letting does not pay. It means the honest figure is net, after tax and voids, not the rent, and if you have never worked that number out, that is the first thing to do before deciding anything.
The time and regulation are real
The other half of "worth it" is not money, it is effort. The Renters’ Rights Act reshaped the job in 2026: periodic tenancies with no fixed term, Section 21 gone so possession runs through Section 8 grounds, Section 13 for rent increases, a pet-request regime, the PRS Database coming, and more record-keeping throughout. Add Making Tax Digital for landlords over the threshold, and the admin is heavier than it was five years ago.
For a landlord with one property who quite enjoys the control, that is manageable. For someone with a couple of lets and a full-time job who finds every certificate a chore, the time cost is a real part of the equation, and it is exactly the part people underestimate when they only look at yield.
Who letting still rewards
Being a landlord in 2026 tends to still be worth it when:
It tends to feel not worth it when a large mortgage collides with Section 24, voids are frequent, and the admin has become a source of dread — that combination is what pushes people to sell.
Your options if the answer is "not sure"
"Not worth it as it stands" does not have to mean "sell". The realistic choices:
How LetCompliance helps with the "run it better" option: it collapses the time cost — advertising, referencing, rent, arrears, compliance scoring and the tax pack in one login, and surfaces the leaks, so the net figure you are judging is the best version of itself, not one dragged down by avoidable voids and missed deductions. If the honest answer is still "sell", at least it is an informed one.

How much profit does a typical landlord actually make?
The honest answer is far less than the rent implies, and seeing it worked through is more useful than any yield percentage.
Take a £250,000 house let at £1,150 a month — £13,800 a year gross. A £180,000 interest-only mortgage at 5.2% costs £9,360 a year.
Running costs on a self-managed let, before tax:
That is £3,930 of costs, leaving £9,870 before finance. Taxable profit, however, is calculated before deducting mortgage interest — that is Section 24, so a higher-rate taxpayer is taxed on £9,870 at 40%, or £3,948, then receives a 20% credit on the £9,360 of interest, worth £1,872. Net tax: £2,076.
Actual cash left: £13,800 minus £3,930 of costs, minus £9,360 of interest, minus £2,076 of tax — about £434 for the year.
That is roughly £36 a month for owning, insuring, maintaining and being legally responsible for a house. Which is the real point: on a mortgaged higher-rate let, the income is not the return. Capital growth and the mortgage being repaid by someone else are the return, and both take years and neither is guaranteed.
Change one variable and it transforms. Unmortgaged, the same property nets several thousand a year. A basic-rate taxpayer keeps considerably more. Two properties spread the void risk. The arithmetic is not an argument against letting — it is an argument against letting one mortgaged property while paying higher-rate tax and expecting monthly income.
Is buy-to-let dead in 2026?
No, but the version of it that worked in 2015 is, and pretending otherwise is how people lose money.
What genuinely changed, and none of it is reversing:
Section 24 removed full mortgage-interest relief, which is what produced the £434 above.
From April 2027, property income is taxed two points higher than earned income — 22, 42 and 47 per cent, and the ordering rules change so your personal allowance is set against employment income first.
Making Tax Digital brings quarterly reporting: gross property income over £50,000 from April 2026, over £30,000 from April 2027, over £20,000 from April 2028. Note that is gross, not profit.
EPC C by 1 October 2030, with a £10,000 cost cap per property. Government modelling puts the average at around £5,400, but a solid-wall Victorian terrace can reach the cap.
The Renters' Rights Act removed fixed terms and Section 21, so possession is slower and every tenant can leave on two months' notice.
Put together, that is a sector that now rewards scale, low leverage and competence, and punishes the casual accidental landlord with one mortgaged flat and a spreadsheet. Which is roughly what every change since 2015 has been designed to do.
The people quietly doing well are unmortgaged or lightly mortgaged, hold several properties, keep voids short and paperwork tight, and treat it as a business rather than a savings account.
Should you sell, and what does it cost to get out?
If the numbers above have you considering it, price the exit before you decide — it is more expensive and slower than most landlords assume.
Capital Gains Tax. Residential property gains are taxed at 18% within your basic-rate band and 24% above it, after the annual exempt amount of £3,000. You must report and pay within 60 days of completion, which catches people who expected to settle it with their next tax return. On a £70,000 gain for a higher-rate taxpayer that is roughly £16,000, payable within two months.
Getting the property back. With a tenant in situ, selling with vacant possession means Ground 1A: four months' notice, unavailable in the first twelve months of the tenancy, and a twelve-month bar on re-letting after the notice expires. From decision to empty house, six months is realistic.
Or sell with the tenant in place. A tenanted sale reaches a smaller pool of buyers and usually a lower price, but it is immediate and you keep collecting rent throughout.
The middle options people forget. Remortgaging onto a lower rate, moving to interest-only to improve cash flow, or selling one property to clear the mortgage on another — that last one converts two thin mortgaged lets into one solid unencumbered one, and is frequently the best answer for a two-property landlord who is tired rather than broke.
Whichever way you go, the decision needs numbers you trust. LetCompliance keeps rent, expenses and the per-property position in one ledger and produces SA105-shaped figures with MTD quarterly summaries — so you stop guessing what the portfolio actually earns before you decide to scale or sell. Start free with one property and see the real number before you decide.

Frequently asked questions
Is being a landlord still worth it in 2026?
It depends on your numbers, and the honest figure is the net one after tax and voids, not the rent. It tends to still be worth it where the mortgage is small or the property is owned outright (so Section 24 barely bites), you are in it long term for capital growth, or you run it efficiently so voids are short and compliance never lapses into a fine. It tends to feel not worth it when a large mortgage collides with Section 24 and the admin has become a source of dread.
Why is my rental making less profit than the rent suggests?
Because the rent is not the number that matters — what is left after costs is. In 2026 those costs bite harder: Section 24 means an individually-owned mortgaged property gets only a basic-rate tax credit for mortgage interest instead of a deduction, voids cost rent and often council tax, and gas/EICR/EPC/maintenance are non-negotiable. Work out the net figure after tax and voids before judging whether it pays.
Should I sell my rental or keep it?
"Not worth it as it stands" does not have to mean sell. Often the profit is leaking through avoidable voids, missed expense claims or a compliance slip that becomes a penalty, and running it better changes the answer. Other options are using an agent for the parts you dislike (the fee comes off the thin net figure), restructuring such as incorporation where the tax case genuinely stacks up (with advice), or selling — a legitimate answer, but weigh the capital gains tax bill first.
