Planning permission is one of the most misunderstood areas of short-let compliance in the UK. Most hosts assume that because they own their property, they can do whatever they like with it — but planning law does not work that way. Whether you need formal consent depends on your local authority, how often the property is let, and changes introduced since 2023 that have fundamentally altered the picture in England.
How planning use classes apply to short-lets
In England, every property sits within a planning use class. A standard residential home falls under Class C3 (dwelling houses). When a property shifts from being someone's primary residence to operating as a short-term rental with no permanent occupier, it may no longer be used as a dwelling house in the planning sense — which can trigger the need to change use class.
Historically, there was no specific use class for short-lets. Local authorities had to argue that a change of use had occurred under general planning principles, which was difficult to enforce and inconsistently applied across different councils. That changed in April 2023 when the government introduced a dedicated use class for short-term lets in England.
The C5 use class and what it changes
From 26 April 2023, a new Class C5 use class came into force in England, covering short-term let properties that are not used as a sole or main residence. If a property is rented on a short-let basis and is not the owner's primary home, it technically falls into C5 rather than C3. Alongside this, new permitted development rights were introduced, meaning a C3 dwelling house can change to C5 use — and back again — without needing a full planning application, unless a local authority has removed those rights.
The practical implication is significant. If you own a buy-to-let flat in, say, Bristol or Nottingham and you want to switch it from long-term rental to short-let, the property shifts from C3 to C5. Under permitted development, that switch is allowed by default — but only where an Article 4 Direction has not been put in place by the council. Properties that were already operating as short-lets before April 2023 benefit from a transitional provision and are treated as lawfully established C5 use, provided they can demonstrate that use existed before the change.
How Article 4 Directions work in practice
An Article 4 Direction is a tool that allows a local planning authority to remove specific permitted development rights in a defined area. In the context of short-lets, it means a council can require hosts to apply for planning permission before converting a C3 home into C5 short-let use. Without the Article 4, the permitted development right applies automatically. With it in place, you must go through a formal application — and the council can refuse it.
Several councils have either introduced or are actively consulting on Article 4 Directions specifically targeting short-lets. Manchester City Council confirmed its intent to introduce such a direction across much of the city. Edinburgh operates its own licensing regime under Scottish planning law (which differs from England — more on that below). Cornwall Council has been particularly vocal about the housing pressure caused by second homes and holiday lets in towns like St Ives, Padstow and Fowey, and has used planning tools aggressively to manage the situation. If you are operating in a high-demand tourist area or a city with a housing crisis narrative, the risk of an Article 4 being applied to your area is meaningfully higher than in a suburban commuter town.
For hosts managing properties in Manchester specifically, checking whether an Article 4 has been designated for your postcode before listing is now a necessary step — not an optional one. The same applies to operators in London, where individual boroughs have different approaches. Westminster and Kensington & Chelsea have historically been stricter than outer London boroughs.
When permitted development still applies
If you live in your property and let it out while you are away — for a holiday, a work trip, or even just for a few weekends a year — the position is different. A property that remains your sole or main residence does not fall into C5 at all. It stays in C3 regardless of how many nights it is let, because the occupation as a primary home is what determines the use class. This is the scenario that covers the majority of casual Airbnb hosts who rent out their own home occasionally.
Where things get more complicated is when someone owns a second home or investment property and converts it entirely to short-let. That is a clear C5 scenario. But there are grey areas: a property rented short-term for most of the year while the owner stays there for a few weeks annually, for example, sits in genuinely contested territory. The 90-night rule in London (under the Deregulation Act 2015) applies to a different question — it limits short-let nights in Greater London for properties that are the host's principal home — and it does not resolve the planning question on its own.
Scotland, Wales and Northern Ireland each operate under separate planning frameworks. In Scotland, short-term let licensing was introduced in 2023, and planning consent may be required as a condition of obtaining that licence — particularly in Edinburgh, which was designated a Short-Term Let Control Zone. Welsh planning policy is also diverging from England. If you are operating outside England, seek advice specific to your jurisdiction rather than relying on England-based guidance.
What happens if you get it wrong
Operating a short-let without the required planning permission is a breach of planning control. The consequences are not immediate — planning enforcement does not work like a fine handed out on the spot — but they are real. A council can issue an Enforcement Notice requiring you to cease the use and potentially restore the property to its former state. Failing to comply with an Enforcement Notice is a criminal offence. In practice, councils tend to act when complaints are made by neighbours or when a property comes to attention through a licensing application or a registration scheme.
There is also a financial risk that many operators overlook. If a property has been used in breach of planning control and you later try to sell it or remortgage it, a solicitor will identify the planning history. Buyers and lenders may require a certificate of lawful use or indemnity insurance, which adds cost and delay. Getting the planning position right from the outset is cheaper than resolving it under pressure.
One thing worth knowing from operational experience: councils are increasingly cross-referencing Airbnb and Booking.com listings with planning records, particularly in coastal areas and city centres. Cornwall, Lake District and Edinburgh have all made public statements about enforcement activity. Assuming you will not be noticed is not a risk management strategy.
Steps to take before you list
The process for checking your position does not need to be complicated, but it does need to happen before you list rather than after.
Check your local planning authority's website for any Article 4 Directions covering short-term lets or C5 use in your area — most councils now publish these in their planning policy documents or have dedicated short-let pages.
If your property is your sole or main residence and you let it occasionally, confirm this in writing with your solicitor or a planning consultant — it is the simplest way to establish that C5 does not apply to your situation.
If you are in Scotland, apply for a short-term let licence through your local council and check whether planning consent is required as part of that process, particularly if you are in Edinburgh.
For any property that is not your main home and is to be let commercially, obtain either written confirmation from the council that no Article 4 applies, or submit a Certificate of Lawful Development application to formally establish the permitted development right on record.
A Certificate of Lawful Development application typically costs around £100 to £200 in fees and takes eight weeks. It is not glamorous, but it gives you a formal document stating that the use is lawful — which protects you on enforcement, on sale and on remortgage. For any commercial short-let operation, it is money well spent.
Hosts operating in Birmingham and Leeds should also monitor their local council planning portals actively through 2025 and 2026, as both areas are expected to consult on short-let planning controls in line with national direction. The situation is moving quickly, and what is permitted development today may require consent within twelve months.
Planning rules interact with other compliance requirements — licensing, council tax, business rates and the forthcoming national short-let registration scheme. None of these operate in isolation, and getting advice from a planning consultant or solicitor familiar with residential short-lets is advisable before you commit significant capital to a property intended for this use.
