Search "UK short-term let rules" and within three results you will read that short-term lets in England now sit in a new C5 planning use class, and that your holiday cottage needs an electrical installation condition report every five years. Neither is true. The first describes a policy announced in February 2024 and never commenced; the second applies a regulation written for people's main homes to properties let by the week.
The rules that genuinely bite are duller: a planning judgement made by your council, a night test that decides whether you pay council tax or business rates, an annual gas check, a fire risk assessment you are the responsible person for, and a tax regime switched off in April 2025.
Rules change often. This was accurate as of September 2026; always confirm with your local authority before acting. Nothing here is legal or tax advice: it explains how the rules work and what to put in front of a solicitor or accountant.
Do you need planning permission for a short-term let in the UK?
There is no national planning permission requirement for short-term letting in England. Permission is needed only if letting amounts to a material change of use, a judgement your local planning authority makes on the facts. GOV.UK's guidance for self-catering hosts puts the decision with the council: it turns on how the property is used and the impact on the local community, and you are told to contact the council to confirm (GOV.UK, letting out a self-catering holiday home in England, updated 15 May 2026).
London is the exception, and it is statutory rather than discretionary. Section 44 of the Deregulation Act 2015 amended sections 25 and 25A of the Greater London Council (General Powers) Act 1973 so that providing temporary sleeping accommodation is not a material change of use where the nights of such use, plus any earlier nights of such use "in the same calendar year, does not exceed ninety", and where the provider was liable for council tax on the premises for each of those nights (Deregulation Act 2015, s.44).
Three details get lost in summaries. The count runs by calendar year, not tax year or rolling twelve months. The council tax condition means the exception was built for someone letting a home they are rated for, not a serviced apartment. And the same section lets a planning authority direct that the exception does not apply in a given area or building. Exceed ninety nights and you have not committed an offence; you have carried out an unauthorised change of use, which a borough can enforce against.
Scotland handles the same question through licensing plus control areas. Licensing is mandatory for holiday cottages, B&Bs, guest houses, rooms in a home and pods or yurts, whatever the length of stay, and hosts trading before 1 October 2022 had until 1 October 2023 to apply. In a control area, currently the City of Edinburgh and Highland Council's Badenoch and Strathspey ward, planning permission for change of use must be applied for or already held before a licence application (gov.scot, short-term lets licensing scheme).

Is the national registration scheme or the C5 use class in force yet?
No. As of September 2026 neither the mandatory national registration scheme for short-term lets in England nor the proposed C5 use class is in force, and no host can register even if they want to.
The scheme has a legal basis in the Levelling Up and Regeneration Act 2023, and the response to the 2023 consultation committed to a mandatory register across England alongside a new use class and permitted development rights, including flexibility to let a main or sole home for up to 90 nights a year. That page still says work "will now begin at pace", and has not been updated since 19 February 2024 (GOV.UK, delivering a registration scheme for short-term lets; consultation on a registration scheme). The host-facing guidance still uses the future tense: the scheme "is expected to begin in 2026", with no portal, commencement date or fee.
The C5 proposal likewise remains a consultation (GOV.UK, introduction of a use class for short term lets). No statutory instrument amending the Use Classes Order to insert C5 could be identified, and independent planning commentary agrees (TLT, a new use class for short-term lettings). Treat "C5 applies to my flat" as unverified until a commencement instrument exists, and treat any site quoting a C5 start date as unreliable on everything else too.
Wales, though, is real. The Visitor Accommodation (Register and Levy) Etc. (Wales) Act 2025 creates a register run by the Welsh Revenue Authority, with the duty to register commencing on 1 October 2026 and covering all paid visitor accommodation, including single-room and occasional lets (GOV.WALES, registering visitor accommodation). The levy is a separate, later step decided authority by authority, so check your county rather than assuming a rate.
Will your holiday let pay business rates instead of council tax?
Only if it passes a two-part night test, which in England is 140 nights available plus 70 nights actually let. Since 1 April 2023 a self-catering property in England is rated rather than council-taxed where it was available to let commercially, with the intention of making a profit, for 140 nights in a 12-month period, actually let commercially for 70 nights in that period, and you intend to keep it available for at least 140 nights next year (GOV.UK, business rates for a self-catering property in England, updated 1 April 2026).
The exclusions are where hosts trip. Maintenance closures, site closures, private use by you and discounted family or friends' stays do not count, unconfirmed future bookings do not count towards the 70, and a stay longer than 28 nights is not a short-term let here. Applications go to the Valuation Office Agency at selfcatering@voa.gov.uk.
Wales sets the bar far higher: 252 nights available in the last 12 months and 182 actually let, plus an intention to remain available for 252. From 1 April 2026 the letting limb can be met as an average of 182 nights per 12 months over the last 24 or 36 months, and up to 14 nights a year donated to registered charities count (GOV.UK, business rates for a self-catering property in Wales, updated 1 April 2026).

Northern Ireland runs its own rating and tourism certification system, outside the scope of the sources above, so do not read the England figures across to Belfast. And passing the test is not automatically good news: whether you gain depends on the rateable value, the reliefs your council operates and how many properties you hold. That is arithmetic for your accountant, with current local figures.

Which safety rules legally apply to a holiday let?
Fire and gas duties apply squarely. The electrical regulation everyone quotes does not.
Fire first. The Regulatory Reform (Fire Safety) Order 2005 covers paying guest accommodation, and the Secretary of State has published guidance under Article 50 of that Order for small premises with a simple layout, limited fire risks and a small number of guest bedrooms let short-term, self-catering included. It carries a fire risk assessment checklist, and the assessment is the duty, not the checklist (GOV.UK, making your small paying guest accommodation safe from fire, published 30 March 2023, updated 20 January 2025). Larger or more complex properties fall under the general sleeping accommodation guidance.
Gas next. Where you provide gas appliances, a check by a Gas Safe registered engineer is required within 12 months of installing a new appliance or flue and annually thereafter, only Gas Safe registered engineers may do that work, and the record must be kept two years and issued to occupants. HSE's landlord guidance states plainly that these duties extend to "rented holiday accommodation such as chalets, cottages, flats, caravans and narrow boats on inland waterways" (HSE, landlords' gas safety FAQs). There is no 28-day or short-stay exemption in it, however often one is asserted in host forums.
Now the myth. The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, source of the five-yearly EICR obligation, apply to a "specified tenancy", defined as a tenancy of residential premises in England that "grants one or more persons the right to occupy all or part of the premises as their only or main residence" (SI 2020/312, regulation 2). A guest staying a week is not occupying your cottage as their only or main residence, so the mandatory five-yearly EICR does not legally apply to a genuine holiday let. The Smoke and Carbon Monoxide Alarm (England) Regulations 2015 use the same only-or-main-residence test (SI 2015/1693, regulation 2).
Do not read that as permission to skip either. Your fire risk assessment will almost always call for adequate detection, faulty wiring is a fire risk you already answer for under the Fire Safety Order, and insurers and lenders often require a current electrical report as a contractual condition. A periodic inspection is strongly advisable. But a site telling you the 2020 Regulations compel it for a holiday let has not read regulation 2.
What replaced the furnished holiday lettings tax regime?
Nothing replaced it. Former FHL properties are taxed as an ordinary property business, and the four advantages that made the label worth having are gone. HMRC's Property Income Manual states that the rules "cease to apply in tax years commencing on or after 6 April 2025 for Income Tax and for Capital Gains Tax, and 1 April 2025 for Corporation Tax" (HMRC, PIM4165).
The four changes, in HMRC's framing (GOV.UK, abolition of the furnished holiday lettings tax regime): the finance cost restriction applies, limiting loan interest relief to basic rate; capital allowances go for new expenditure, with replacement of domestic items relief instead; chargeable-gains reliefs for trading business assets are withdrawn; and the income no longer counts as relevant UK earnings for pension relief. Profits are also no longer calculated separately from the rest of your property income.
Two further obligations are easy to miss because they are not holiday-let specific. Making Tax Digital for Income Tax began on 6 April 2026 for sole traders and landlords with qualifying income over £50,000, with the £30,000 tier on 6 April 2027 and the £20,000 tier on 6 April 2028; qualifying income is gross self-employment and property income before allowances or expenses (GOV.UK, when you need to use Making Tax Digital for Income Tax, updated 26 March 2026). Quarterly updates and digital records change how the books are kept.
VAT is the other. Unlike residential rent, holiday accommodation is a taxable supply: HMRC says that if you supply holiday accommodation "you must account for VAT at either the standard rate (or the temporary reduced rate) on any charges that you make regardless of the length of occupation" (VAT Notice 709/3). The registration threshold is taxable turnover over £90,000 in the last 12 months (GOV.UK, VAT registration). A three-property portfolio at decent rates gets closer to that than most owners expect.

Common mistakes hosts make with UK short-term let rules
The most expensive is treating the London 90-night rule as national. It is a Greater London provision with a council tax condition attached and says nothing about a cottage in Cornwall. Next is assuming the registration scheme or C5 use class already applies, then paying an intermediary to "register" or deciding a future register makes local planning irrelevant.
Others recur constantly. Counting your own stays and mates'-rates weekends towards the 70-night limb, which the guidance excludes. Assuming business rates are automatically cheaper. Believing the five-yearly EICR is mandatory for a holiday let, or using its absence to justify no inspection at all. Filing returns as though the FHL regime still exists. And assuming the platforms police any of it: Airbnb's London night limiter is a product feature, not a legal safe harbour, and it cannot see your direct or Vrbo nights.
Turning the rules into something your calendar can enforce
Almost every duty above becomes a calendar or document problem. A night cap is cumulative, so it must hold across Airbnb, Booking.com, Vrbo and your direct site at once, and those channels do not talk to each other by default. The 28-night boundary in the rates test, and the 140/70 arithmetic, come out of availability and stay-length settings. Gas records, fire risk assessments and electrical reports need renewal dates attached, not an email thread.
This is where a channel manager earns its fee for a UK host: one calendar of record, minimum and maximum stay rules pushed everywhere, availability blocks that hold on every channel, and an export for your accountant when the VOA asks how many nights you let. Uplisting suits smaller UK portfolios, priced in sterling from GBP 40 a month for up to four units, with detailed minimum-stay and availability rules. If the problem is consolidating calendars and messaging cheaply, Hospitable has a free Essentials tier with unlimited properties, a unified inbox and automated messaging. Our comparison of vacation rental software for UK hosts sets both against the alternatives on price and UK fit.
None of this makes anyone compliant. Software records nights, stores certificates and enforces the rules you configure; it does not decide whether your use is a material change of use, and it will push a 91st night in Islington if you tell it to. Use it to make the numbers auditable, then let a planning consultant and an accountant handle the judgement calls. For expiry dates across several properties, our guide to tracking licences and permits with software shows how to structure that, and the fire safety compliance walkthrough pairs well with the Article 50 assessment.
Sizing: one to four UK units, Hospitable's free tier or Uplisting's four-unit plan; five to fifteen, Uplisting's per-property Operator pricing; fifteen and up, run a real procurement against the comparison above.
