Yes, you can rent your London home on Airbnb, subject to the 90-night rule. London law permits whole-property short-term lets of up to 90 nights per calendar year without planning permission. Beyond 90 nights, a Change of Use application to the local borough council is required. If you rent a spare room while continuing to live in the property, the 90-night limit does not apply. Before listing, also check your lease (if the property is leasehold), your buildings insurance, and your mortgage terms, as some restrict short-term letting.
