A holiday let refused on a C3 dwelling: a walkthrough

A holiday let change of use refusal usually arrives as an enforcement notice rather than as a refused application, because the owner never applied. This walkthrough follows an illustrative composite of a two bedroom flat let short term outside London, assembled from the way these cases typically run rather than from any single real decision. No outcome here is quoted from a real appeal.

The flat had planning permission as a dwelling in Class C3. The owner let it on nightly bookings for most of the year, averaging around 200 nights of occupancy, with changeovers two or three times a week and a key safe by the communal door.

The flat, its lawful use and the letting pattern

The building was a converted Victorian terrace with four flats and a shared entrance, hall and bin store. The planning history showed a 1987 permission for conversion to four self-contained flats, with no condition restricting occupancy.

So the lawful use was residential in Class C3. The question was whether letting it on a nightly basis to successive groups of visitors had changed that use to something else.

Nothing physical changed. No extension, no new door, no sign. The entire case turned on the pattern of occupation.

Whether a material change of use had occurred

Section 55 of the Town and Country Planning Act 1990 makes a material change in the use of a building development. Whether short term letting of a dwelling crosses that line is a matter of fact and degree, which is a phrase that sounds evasive and is actually the whole answer.

The Court of Appeal considered holiday letting of a dwelling in 2012 and confirmed that it can amount to a material change of use depending on the circumstances. That decision is indicative of how the courts and inspectors approach the question rather than a rule that produces a given answer, and it is read alongside the facts of each case.

The factors that recur are the frequency of changeover, the number of occupants relative to the dwelling, whether the property is ever used as a home, the degree of commercial management, and the effect on the character of the building and its neighbours.

London is different by statute. Section 25 of the Greater London Council (General Powers) Act 1973, as amended by the Deregulation Act 2015, provides that short term letting of residential premises in Greater London for no more than 90 nights in a calendar year is not a material change of use, subject to conditions including that the property is liable for council tax. Outside Greater London there is no equivalent statutory allowance, which surprises a lot of owners who have read about the 90 night rule.

A registration scheme for short term lets in England and a new use class for them have both been announced, and the commencement position needs verifying against the current position on gov.uk before anyone relies on either.

The evidence the council gathered

The council's enforcement team built the case from public and administrative sources, which is the normal pattern.

• dated screenshots of the listing showing nightly availability, maximum occupancy and the minimum stay
• the review history, which gave dated evidence of occupation stretching back several years
• the booking calendar visible on the listing, showing blocked and available nights
• council tax and business rates records, including whether the property had moved to non-domestic rating
• a log kept by a neighbour recording arrivals, departures and refuse left in the shared hall
• waste collection records showing repeated additional collections

The neighbour log did the most work. Contemporaneous, dated records of actual events are the evidence inspectors find persuasive, far more so than general complaints about disturbance.

The enforcement notice and the appeal ground

The authority served an enforcement notice alleging a material change of use from a dwelling in Class C3 to use for short term holiday letting, and requiring that use to cease.

An appeal against an enforcement notice runs on the statutory grounds in section 174(2) of the 1990 Act. The three that mattered here were ground (c), that there had been no breach of planning control because no material change of use had occurred, ground (d), that the time for enforcement had expired, and ground (a), that planning permission ought to be granted for what had happened.

Ground (c) was the real fight and it failed on the facts. Two hundred nights of nightly letting with multiple weekly changeovers, no residential occupation at any point in the year, and commercial management through a platform was found to be a different use from a dwelling.

Ground (d) failed on evidence. The Levelling-up and Regeneration Act 2023 moved the enforcement time limits in England towards a uniform ten year period, and the commencement position and its application to a particular breach need checking case by case. Here the listing's own review history showed the use starting well inside any applicable period, which is the irony of building an evidence trail for marketing purposes.

Amenity, refuse and management objections

Ground (a) was argued in the alternative and this is where the planning merits were tested.

The objections were specific. Noise and disturbance through party walls and the shared stair at changeover times, including late arrivals. Refuse presented on the wrong days and left in the shared hall, because transient occupants do not learn the collection cycle. Loss of a dwelling from the housing stock, which engaged a local plan policy resisting the loss of residential units. And the absence of any on-site management to respond to problems.

A Noise Impact Assessment was commissioned to address the first point, and it helped less than the owner hoped. Measured sound insulation between the flats met the standard applicable at conversion, but the complaint was about the timing and unpredictability of events rather than about levels. A Waste Management Strategy setting out a lockable store, a managed collection arrangement and instructions in the welcome pack was more useful, because it answered a specific, remediable harm.

The housing loss policy was the hardest point. Where a local plan protects residential units, converting one to visitor accommodation needs a positive case, and tourism benefit rarely outweighs it on a single flat.

The outcome and the condition imposed

In the composite, the inspector dismissed the appeal on grounds (c) and (d) and allowed it in part on ground (a), granting a temporary permission for three years subject to conditions.

The conditions were tight. A cap on the number of nights let in any calendar year. A maximum occupancy of four persons. No arrivals or departures between 22:00 and 07:00. A management plan approved in writing, with a named contact available 24 hours. Refuse to be stored in a designated lockable store. And a requirement to maintain a register of lettings available for inspection by the authority.

The condition the owner found most expensive was the night cap, because it removed the summer peak above the cap. The condition that actually changed the neighbours' experience was the arrival and departure restriction.

What a lawful arrangement would have looked like

Three routes existed and none of them was taken in time.

1. Apply for planning permission for the change of use before starting, with a management plan and a Planning Statement addressing the housing loss policy and the amenity case. Expensive and slow, and it produces a permission that adds value on sale.
2. Apply for a certificate of lawfulness of proposed use or development under section 192 of the 1990 Act, which establishes whether the intended letting pattern needs permission before any money is spent on it.
3. Keep the letting pattern below the threshold where it becomes a material change of use, which outside London means a mixed use with real residential occupation rather than a number of nights, and which is harder to evidence than owners expect.

The fourth route, doing it quietly and relying on time limits, is the one most owners choose and the one the listing itself undermines, because the review history is a dated public record of the breach.

This is general guidance, not legal advice, and the walkthrough is illustrative rather than a report of a real decision. A lawful development certificate is the only formal way to confirm that a use is lawful. Check the position with your local planning authority or a qualified professional before relying on it.
