Should a landlord sell up or keep letting?

It depends — and on a short list of things you can actually price. The Capital Gains Tax you would pay on the way out; the compliance spending you carry by staying; your time horizon; whether there is a mortgage; the cost of bringing the property up to the energy standard coming in 2030; and whether it is a flat with a service charge you do not control. Work those six out and the answer usually stops being a judgement call.

There is no general answer here. A landlord with one unmortgaged house, a long horizon and an EPC of C is in a different position from one with a leasehold flat, a mortgage and an F rating — on the same street.

What selling costs: Capital Gains Tax

This is the part people guess at, and the guesses are usually wrong. The figures below were read from GOV.UK on 24 October 2026. Check them again before you act.

• Rates. If you are a higher or additional rate taxpayer, GOV.UK says "you'll pay 24% on your gains from 6 April 2026". For a basic rate taxpayer it turns on the size of the gain: add the taxable gain to your taxable income, and if the total sits inside the basic Income Tax band "you'll pay 18% on your gains made from 6 April 2026", with 24% above that band. A large gain can therefore be taxed partly at each rate even if your income alone keeps you a basic rate taxpayer.
• Annual exempt amount. The Capital Gains tax-free allowance is £3,000 (£1,500 for trusts). That is all of it, per person, per tax year — a jointly owned property has two allowances against it.
• Private Residence Relief. It does not rescue a property you never lived in. The first condition GOV.UK sets for automatic relief is that "you have one home and you've lived in it as your main home for all the time you've owned it". A buy-to-let bought to let fails at that line. If you lived in it for part of your ownership, partial relief may apply — ask an accountant.
• The deadline that catches people. "You must report and pay any Capital Gains Tax due on UK residential property within 60 days of completing the sale of the property." Sixty days from completion, not from the end of the tax year, and GOV.UK warns you "may have to pay interest and a penalty if you do not report and pay on time". If you are in Self Assessment, you include the sale in your return as well.

What staying costs: the running load

Letting is not a passive asset. The recurring obligations include the annual gas safety check, electrical safety, smoke and carbon monoxide alarms, deposit protection in an authorised scheme within the cap (up to five weeks' rent where annual rent is under £50,000, six weeks at or above it) and, since 1 May 2026, written information about the key terms of the tenancy for new tenants. Large HMOs need a licence from the local council, and some councils operate additional or selective licensing schemes on top.

Two things on the horizon change the arithmetic:

• Energy. The current legal minimum is unchanged: since 1 April 2020 a landlord cannot let, or continue to let, a property covered by the MEES Regulations with an EPC rating below E unless a valid exemption is registered. The higher standard is announced policy, not yet law. The Government's consultation response says private landlords of all tenancies must comply with the higher standard by 1 October 2030, investing up to £10,000 per property to get there, with the enabling regulations intended to come into force in 2027. See our guide to EPC ratings for rented property.
• Registration. The Renters' Rights Act creates a Private Rented Sector Database. All landlords of assured and regulated tenancies will be legally required to register themselves and their properties on it; rollout commences from late 2026, with an annual fee, and registration will also be a precondition of using certain possession grounds. See when to register.

None of that is fatal on its own. It is a cost line, and it belongs in the hold case rather than the back of your mind.

If you do sell: the two routes

You can sell with the tenant in place — the tenancy continues and the buyer becomes the landlord — or with vacant possession, which means ending the tenancy first. Since 1 May 2026 that means Ground 1A: four months' notice, and a restricted period running from service until twelve months after the earliest date proceedings can begin, so roughly sixteen months in which you cannot let the property or market it to let. That is the least reversible decision in this article, and it is set out in full in selling a rented property with tenants. Either route, budget honestly for time — see how long it takes to sell.

The four things that usually decide it

1. Time horizon. Transaction costs — agency, legal, tax, voids — are front-loaded, and a short hold rarely earns them back. A long one changes what the 2030 spend is worth.
2. The mortgage. An unmortgaged property absorbs a void or a £10,000 upgrade; a geared one may not. Check early repayment charges before assuming you can exit cleanly.
3. Condition, and the cost of the standard. Get a current EPC and a quote for the measures it recommends. A solid-wall terrace and a 2015 flat are not the same problem, and guessing here is how hold cases go wrong.
4. Leasehold. A flat brings a service charge, a ground rent and possibly a major works bill you cannot vote away. Read the last three years of service charge accounts before you decide.

Run it, don't feel it

Put both cases on one page: net proceeds after costs and tax, against net annual return after the compliance spend you have just listed. Our calculators will do the arithmetic, and our fees page sets out what a sale or a let costs with us. The tax is not a calculator question — a gain computation with reliefs, part-occupation and joint ownership needs an accountant, and the 60-day clock runs either way.
