Yes, if five or more people from two or more households share facilities. That's a mandatory HMO licence everywhere in England. Many London boroughs go further, with additional licensing for HMOs with three or four sharers and selective licensing for ordinary lets in some or all wards.
Some 2026 examples: Brent has required additional HMO licences for three or four sharers since 2 February 2026, and runs selective licensing across the borough except Wembley Park. Ealing licenses small HMOs across the whole borough until 31 March 2027, and has consulted on renewing the scheme for another five years. Harrow extended selective licensing to six wards during 2026, from Edgware and Roxeth in May to Wealdstone North and South in September.
Letting without the right licence risks a civil penalty of up to £40,000, and tenants can apply for a Rent Repayment Order, which the Renters' Rights Act has doubled to up to 24 months' rent. We check which schemes apply to every property we take on and handle the applications and renewals.
