Questions about small HMO conversions (3–6 sharers) in Bristol

Can I keep a lounge in a small HMO?

Yes, and many councils expect some shared living space where bedrooms are at the smaller end of the size range. We plan the layout so the house works for sharers and meets the local standard.

Does a small HMO need a licence?

In England a mandatory licence is needed when five or more people from two or more households share, and smaller HMOs can need one where the council runs additional licensing. Wales still applies a three-storey test, while in Scotland and Northern Ireland every HMO needs a licence. We check the address and tell you which applies before quoting.

Do you carry out small HMO conversions (3–6 sharers) 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.
