Holiday lets, short term rentals and the use class question

There is no holiday let use class in England. A dwellinghouse is Class C3, and letting it to visitors for short stays does not automatically move it out of C3 or into anything else. Whether planning permission is needed turns on a single question of fact and degree: has the character of the use changed materially? Sometimes it plainly has. Often it plainly has not. The uncomfortable middle is where most owners sit.

That framing matters because a great deal of advice treats short-term letting as either obviously lawful or obviously unlawful. Neither is right, and the answer differs between a spare room let for ten weekends a year and a four-bedroom house let to changing parties of eight every weekend of the summer.

Whether short term letting is a change of use at all

Section 55(1) of the Town and Country Planning Act 1990 makes a material change in the use of land or buildings development, which needs permission. Use as a dwellinghouse falls in Class C3 of the Town and Country Planning (Use Classes) Order 1987 as amended, and short-term letting is not listed anywhere in the Order as a separate class.

So the question is not which class you have moved into. It is whether the use has changed in character to a material degree. The Court of Appeal considered exactly that in Moore v Secretary of State for Communities and Local Government in 2012, in a case about a large country house let out for short periods, and confirmed that the answer is a matter of fact and degree for the decision-maker on the particular facts. That decision is indicative of how the question is approached rather than a rule that short-term letting is always a change of use.

The practical consequence is that no blanket answer exists, and anyone offering one is guessing.

The factors that point to a material change

Officers and inspectors look at the same cluster of things, and they look at them together rather than one at a time.

• Whether the property remains anyone's home. A house let out for 50 weeks a year with no resident owner looks different from a home let while the family is away.
• Intensity and frequency. Occupation for a few weeks of the year reads as incidental. Continuous turnover every two or three days reads as a business operating from a residential building.
• Group size and composition against the property's normal occupancy. Eight unrelated adults in a three-bedroom terrace is a different use from a family of four.
• Comings and goings. Arrivals by car at changeover, luggage, taxis, and the concentration of that movement on Friday and Sunday afternoons.
• Disturbance. Noise late at night, use of outdoor space, and the absence of any continuing relationship with neighbours.
• Ancillary commercial activity: key safes, a cleaning round, laundry deliveries, on-site management, signage.
• How the property is marketed and priced, including minimum stay rules and whether it is presented as a whole-property let.

None of these is decisive on its own. A high score across several of them is what produces an enforcement notice.

Flats carry extra risk. Where the building is in shared ownership or has a management company, the lease often prohibits short lets outright, which is a contractual matter independent of planning but frequently the thing that actually stops the operation.

London's ninety-night rule

Greater London has a statutory answer that the rest of England does not. Section 25 of the Greater London Council (General Powers) Act 1973, as amended by section 44 of the Deregulation Act 2015, provides that using residential premises in Greater London as temporary sleeping accommodation is not a material change of use where the use does not exceed 90 nights in a calendar year and the person providing the accommodation is liable for council tax on the premises.

Three points follow.

1. The 90 nights are counted per calendar year and per premises, not per booking or per host.
2. Exceed the limit and the ordinary material change of use test applies, which in London usually means the borough will say permission was required.
3. Boroughs may apply to the Secretary of State to disapply the exemption for particular premises or areas, so the allowance is not universal across London.

Keep a nightly occupancy record. In an enforcement investigation the burden of showing the use is lawful sits with the owner, and a booking export with dates is the only evidence that answers the question directly.

Control areas and local policy elsewhere

Outside London, England has no equivalent statutory allowance. Some authorities have adopted local plan policies resisting the loss of housing to short-term letting in coastal and tourist areas, and those policies bite when an application is made.

Two devolved regimes work differently and are worth knowing if you own across borders.

In Wales, the Town and Country Planning (Use Classes) (Amendment) (Wales) Order 2022 created Class C5 for dwellings used otherwise than as a sole or main residence, and Class C6 for short-term lets, with permitted development rights allowing movement between C3, C5 and C6 unless withdrawn by an Article 4 direction. Several Welsh authorities have made exactly that direction. Planning Policy Wales and the relevant Technical Advice Notes apply.

In Scotland, the Town and Country Planning (Short-term Let Control Areas) (Scotland) Regulations 2021 let planning authorities designate control areas in which using a whole dwelling for short-term lets is treated as a material change of use requiring permission. A separate licensing regime applies across Scotland under civic government licensing powers, and National Planning Framework 4 is the policy context.

Registration, licensing and what is proposed

The Levelling-up and Regeneration Act 2023 contains powers for a registration scheme for short-term rental properties in England, and the government has consulted on introducing a separate use class for short-term lets together with permitted development rights to move between it and C3.

As at September 2026, the position on both has moved more than once and commencement has been staged. Check the current status on gov.uk before you rely on anything here, and do not assume that a registration number, once a scheme exists, answers the planning question. Registration and planning permission are separate requirements, in the same way that a licence for a house in multiple occupation has never substituted for permission.

Evidence of the pattern of occupation

If a council opens a file, it will assemble the evidence from public sources first: dated listing screenshots, review dates and counts, calendar availability, minimum stay settings, and complaint records from neighbours or environmental health. Officers may also log vehicle movements and changeover activity over a period of weeks.

Your own records are the counterweight. Keep nightly occupancy by date, the identity of the property as a home during the remainder of the year, council tax or business rates status, and correspondence showing continued residential use. Where the letting is seasonal, the record should show it.

Enforcement time limits changed under the Levelling-up and Regeneration Act 2023, which moved the periods in section 171B of the Town and Country Planning Act 1990 towards a single ten-year period in England. Verify the commencement position for your circumstances rather than assuming the older four-year rule for a change of use to a single dwellinghouse still applies.

Where permission is the right answer, the application is a change of use application, and it stands or falls on amenity, parking, waste and the loss of a residential unit. The evidence pack for a change of use application sets out what to assemble, and PlanScope can draft the Planning Statement that ties the evidence to the adopted policies for review before submission.

Where the position remains unsettled

Two things are unresolved rather than merely complicated.

The first is where the line sits for a property that is both a home and a let. There is no threshold outside London, and two authorities can reach different views on similar facts without either being wrong in law.

The second is what happens to existing operations if a new use class arrives. Any transition will have to deal with uses that were lawful under the fact and degree test, and the detail of that transition is exactly the kind of thing that changes between consultation and commencement.

If you are buying with short-term letting in mind, price that uncertainty rather than ignoring it, and check whether the title or the planning history already carries a condition restricting occupancy, which is dealt with in conditions restricting use class or occupier.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
