Thinking about turning your property into a holiday let? Before you list it on Airbnb or another booking platform, there are several holiday let rules & regulations you need to check. Planning permission, the London 90-night rule, safety requirements, tax, business rates, insurance and upcoming registration rules can all affect whether and how you can operate.
For Cribs Estates landlords, London is especially important. The rules for short-term letting in the capital are not the same as simply renting a property to a long-term tenant, so it is worth checking the position before accepting your first booking.
Can you legally use your property as a holiday let?
The first question is not how much you can earn. It is whether you are actually allowed to use the property for short-term stays.
Before advertising, check:
-
Planning: Your local council decides whether planning permission is needed for the property's use.
-
Mortgage: Your mortgage provider may have restrictions on short-term or holiday letting.
-
Lease: If the property is leasehold, check whether your lease or freeholder limits short-term letting.
-
Insurance: Your existing home or landlord policy may not cover paying guests.
In London, City Hall specifically advises property owners to check permissions with their landlord or freeholder, mortgage provider and insurer before starting short-term letting.
What is the 90-night rule for holiday lets in London?
The 90-day holiday let rule is one of the most important regulations for London landlords.
If you use a residential property in London as short-term accommodation, you can generally do so for a maximum of 90 nights in a calendar year without planning permission, provided the required Council Tax condition is met. Going beyond 90 nights requires planning permission from the relevant local council.
The limit runs from 1 January to 31 December, so it is not a rolling 90-day allowance.
What holiday let safety rules apply?
Holiday accommodation must be safe for paying guests. Current government guidance for England covers several areas that landlords need to consider, including:
-
Fire safety
-
Gas and carbon monoxide safety
-
Electrical safety
-
Energy Performance Certificates (where required)
-
Suitable insurance
-
TV and music licensing where applicable
The government recommends dedicated holiday-let insurance, public liability cover and building and contents insurance suitable for short-term letting. It also directs holiday-let owners to the relevant fire, gas and electrical safety guidance.
Rather than assuming that your normal landlord checks are enough, check the requirements for the property and the type of accommodation you are providing.

Do holiday lets pay Council Tax or business rates?
Your tax position and your property's business-rates position are separate questions.
In England, a self-catering property may be assessed for business rates rather than Council Tax if it meets specific conditions. The property must:
-
Be available for commercial letting for at least 140 nights in the previous 12 months
-
Have actually been let for at least 70 nights in the previous 12 months
-
Be intended to be available for commercial letting for at least 140 nights in the next 12 months
-
Be let for short periods of 28 nights or less
If you only let one property in England and its rateable value is below £15,000, you may also qualify for Small Business Rate Relief, subject to the applicable rules.
These figures should not be confused with the old Furnished Holiday Let tax tests.

What happened to the Furnished Holiday Let tax rules?
This is one area where older holiday-let articles can give landlords the wrong impression.
The government abolished the Furnished Holiday Let (FHL) tax regime on 6 April 2025. From the 2025–26 tax year, income from short-term holiday accommodation is taxed under the usual residential landlord rules, and the previous FHL tax reliefs no longer apply.
So if you are reading an older article that tells you to meet the old FHL tax thresholds to receive special tax treatment, check its publication date carefully.
The rules for business rates are a separate matter, which is why the 140-night and 70-night figures above can still be relevant.
Do holiday lets need a licence or registration in England?
England is moving towards a mandatory national registration scheme for short-term lets, but the current GOV.UK guidance says the scheme is expected to begin in 2026 and is not yet in force.
That means landlords should not assume that an England-wide holiday-let registration requirement is already operating.
Local requirements can still apply, however. The government advises owners to contact their local authority to check planning requirements, how registration will work in their area, required documentation and any additional local rules.
The position is also different across the UK. Scotland already operates a short-term-let licensing system, for example, so landlords should check the rules for the specific nation where their property is located.
What happens if you get the rules wrong?
The biggest risk is assuming that a property can be used as a holiday let simply because other properties nearby are doing it.
In London, properties used for short-term letting beyond the permitted 90 nights without the required planning permission can face planning enforcement action from the local council.
You could also run into problems with your mortgage, lease, insurance or safety obligations if you have not checked them before starting.
