HMO sound insulation reduces noise passing between letting rooms, floors and neighbours. In Portsmouth, a place of roughly 210,000 people in Hampshire, the work is planned around the HMO rules for England and the council’s written HMO standards. With students as well as working sharers renting in Portsmouth, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Portsmouth?
Sound insulation in Portsmouth must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Where the building regulations apply to a conversion, Part E sound requirements can apply between rooms and floors.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
