Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
BS 7671, the wiring standard, calls for arc fault detection devices in HMOs on new socket circuits, such as rewires and consumer unit changes.
Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.

Questions about ensuite installation in Bristol

Can an ensuite go anywhere?

It needs a route for waste water. Gravity drainage is best; where that is not possible, a macerator or pump can work. We check at the survey.

How noisy are macerators?

Modern units are quieter than older ones but still audible. We use them only where gravity drainage is not possible and fit them to reduce noise.

Do you carry out ensuite installation across Bristol?

Yes, across the whole of Bristol, including Bristol.

Who licenses HMOs in Bristol?

HMOs in Bristol are licensed by the local council for the address. Where an area has several councils, each runs its own licensing and planning policies.
