An HMO ensuite is a small private shower room, with a WC and basin, built into or next to a letting room. Southampton is 43 miles south-west of Reading. We price ensuite installation there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. With students as well as working sharers renting in Southampton, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Southampton?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Southampton before we price.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- BS 7671, the wiring standard, calls for arc fault detection devices in HMOs on new socket circuits, such as rewires and consumer unit changes.
