HMO Plumbing & Licensing in Kensington & Chelsea
If you let a shared house or flat in Chelsea, licensing and plumbing standards go hand in hand. The Royal Borough of Kensington and Chelsea runs both mandatory and additional HMO licensing, and getting the bathrooms, hot water and safety right is part of staying compliant. A quick guide for landlords and agents.
Mandatory HMO licensing applies to houses in multiple occupation with five or more occupiers forming two or more separate households who share facilities. On top of that, RBKC introduced an Additional HMO licensing scheme that started on 1 June 2023 and runs borough-wide for five years, capturing smaller HMOs — broadly those with three or more people in two or more households sharing amenities — that fall outside the mandatory scheme. In short, most shared lets in Chelsea now need a licence of some kind.
The penalties for getting it wrong are serious: operating an unlicensed property that needs a licence can bring a civil penalty of up to £40,000 per property, rent repayment orders, and difficulty serving a Section 21 notice, with agents potentially jointly liable. Licences run for up to five years, and the council sets application fees per property.
Plumbing sits at the heart of the amenity standards a licensed HMO must meet: an adequate number of bathrooms, WCs and wash-hand basins for the number of occupants, a constant supply of hot and cold water to each, and adequate heating in all occupied rooms. A larger HMO may need a hot-water cylinder or system sized so several occupants are not left cold, plus thermostatic controls to reduce scald risk. An annual Gas Safety certificate is required where there is gas.
Legionella risk also needs a simple assessment and sensible controls — avoiding dead legs in pipework, keeping hot water hot and cold water cold, and flushing infrequently used outlets. Emergency Plumber Chelsea helps landlords upgrade bathrooms, size hot-water systems and fix compliance gaps across SW3 and SW10. Call 020 3002 6667.
Quick tips
- Chelsea's additional licensing scheme (from 1 June 2023) means many 3-4 person HMOs need a licence, not just large ones.
- Provide enough bathrooms/WCs and reliable hot water for the number of occupants — it is a licence condition.
- Keep the annual Gas Safety certificate current where gas is present.
- Do a Legionella risk assessment: no dead legs, hot water hot, cold water cold, flush unused outlets.
