Holiday let planning permission and occupancy conditions

Letting a house or flat to holidaymakers does not automatically need planning permission, and it does not automatically avoid it either. Whether holiday let planning permission is required turns on whether the letting amounts to a material change of use under section 55 of the Town and Country Planning Act 1990, which is a question of fact and degree rather than a rule you can look up. Occasional letting of your own home while you are away sits at one end. Year-round commercial letting of a property nobody lives in, with weekly turnover and a key safe by the door, sits at the other.

London is the exception, because there the answer is written into statute.

When short-term letting becomes a material change of use

A dwellinghouse in use class C3 can be occupied by its owner, by a family, by tenants on an assured shorthold tenancy or by a succession of holidaymakers, and none of those is inherently a different planning use. What changes the analysis is the character of the use, judged on the ground.

The courts have accepted that intensive commercial holiday letting of a dwelling can amount to a material change of use, decided as a matter of fact and degree in each case. The factors that come up again and again are the frequency of changeover, whether the property is available all year, whether anyone lives there between lettings, the number of separate occupier groups, the arrival and departure pattern, and the effects on the neighbours: vehicle movements, late arrivals, refuse presented outside collection days, noise from gardens and hot tubs.

None of those is decisive alone. Together they describe whether the property is still functioning as a home or has become, in planning terms, a small hospitality business.

The London 90-night rule

Greater London runs on a different footing. Section 25 of the Greater London Council (General Powers) Act 1973 makes the use of residential premises as temporary sleeping accommodation a material change of use, so it needs permission. The Deregulation Act 2015 then carved out an exception: letting for no more than 90 nights in a calendar year is not treated as a change of use, provided the conditions in the Act are satisfied, including that the person providing the accommodation is liable for council tax on the premises.

Cross 90 nights in a calendar year and you are back in the permission regime for the whole of that use. The 90 nights are counted across the calendar year, not per booking or per guest, and the burden of showing you stayed inside the limit falls on you if the borough asks.

Boroughs enforce this. Keep booking records, dated, for each let.

Evidence of intensity, and who has to produce it

Where a council suspects an unauthorised change of use, its planning enforcement team will build a picture rather than rely on one complaint. Listings and calendars, turnover of occupiers observed on site, refuse and recycling patterns, complaint records held by environmental health, licensing records where they exist, and council tax or business rates status all feed in.

The same evidence works for you in reverse. If you are applying for permission, or arguing that no permission is needed, produce it yourself: a booking log showing nights let and nights the owner was in occupation, a parking record, a note of how refuse is managed between lets, and the management arrangements for arrivals and noise. A planning statement that sets that evidence out plainly is worth more than one that argues the law at length and leaves the facts to the officer's imagination.

Local policies on the loss of permanent homes

Several authorities in tourism pressure areas have adopted local plan policies that resist the loss of dwellings from the permanent housing stock, or that require a scheme to demonstrate no material harm to housing supply and to residential amenity. Coastal districts, National Park authorities and parts of Greater London are the common ones.

Check the adopted local plan and any supplementary planning document before assuming the application is a formality. Where such a policy exists, the application has to answer it directly, usually with evidence about the property's suitability as a permanent home, its history of occupation and the effect on the character of the street. Where a house is being carved up as well as converted in use, the tests overlap with those for converting a house into flats, and the two applications are often better made together.

The conditions councils offer, and the ones to negotiate

Where permission is granted, expect conditions. The recurring ones are:

• restriction of occupation to holiday use only, with a bar on use as a sole or main residence
• a maximum continuous stay, often expressed in days within a rolling period, to prevent drift into permanent occupation
• a requirement to keep an up-to-date register of occupiers, their home addresses and dates of stay, available to the council on request
• a management plan covering arrivals, departures, refuse storage and presentation, and contact details for a responsible person
• limits on the use of external areas after a stated hour, sometimes with a specific restriction on hot tubs
• parking provision to be laid out and retained

Two of these are worth engaging with before they are imposed. A register condition that names the format is easier to comply with than a vague one. And a management plan condition is better discharged with a document you drafted than one written to satisfy an officer after refusal of discharge.

Where noise from external areas is the officer's concern, a short noise impact assessment prepared to the usual standards is generally more persuasive than an offer of a curfew, because it gives the council something to condition and to enforce against.

Certificates of lawfulness for an existing holiday use

If the property has already been let as a holiday unit for years, a Lawful Development Certificate for an existing use under section 191 of the Town and Country Planning Act 1990 is the way to put the position beyond argument. It is not an application for permission. It asks the council to certify that the use is lawful because it has continued beyond the enforcement time limit, or because it never amounted to development at all.

The Levelling-up and Regeneration Act 2023 changed the enforcement time limits in England to ten years. Verify the commencement position and the limit applying to your circumstances before building a case on any shorter period, because the answer depends on when the use began.

Evidence has to be specific and it has to cover every year of the period claimed. Booking records, bank statements, invoices from cleaners, advertising archives, utility bills and sworn statements from people with direct knowledge. Gaps sink these applications more often than weak individual documents do.

Wales: a different set of use classes

This section applies to Wales only. Wales amended its Use Classes Order in 2022 to create separate classes for dwellings used as second homes and for short-term holiday lets, so a change between permanent residential use and short-term letting can itself require permission, and several Welsh authorities have made Article 4 directions on top. Anyone letting in Wales should check the current Welsh classes and any local Article 4 direction rather than reading across from the English position. Scotland operates a separate short-term let licensing regime alongside planning control, and Northern Ireland has its own framework again.

What to do next

Work through it in order. Establish where the property is and whether the London statute applies. Assemble the occupancy evidence before you form a view on whether a change of use has happened. Read the adopted local plan for a policy on loss of dwellings. Then decide between an application for permission, a certificate of lawfulness, or scaling the letting pattern back below the threshold that concerned you in the first place.

This is general guidance, not legal advice. A Lawful Development Certificate is the only formal way to confirm that an existing use is lawful, and you should check the position with your local planning authority or a qualified professional before relying on anything here.
