In short: A shared bathroom refit replaces worn or failing bathrooms in an HMO with hard-wearing, easy-clean ones: good extraction, waterproofing, thermostatic showers and finishes that stand up to several users a day. We carry this out across Dorset, priced against the HMO rules for England and the council’s own standards.

Which rules apply in Dorset?
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
- Councils assess hazards, including damp, mould and fire, under the HHSRS; revised regulations and guidance applied from 23 June 2026.
- Electrical installations must be inspected and tested at least every 5 years; remedial work is due within 28 days, or sooner if the report says so.
- Councils can fine up to £7,000 where a Category 1 hazard is not removed when it reasonably could have been.
- BS 7671, the wiring standard, calls for arc fault detection devices in HMOs on new socket circuits, such as rewires and consumer unit changes.
Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.
