HMO sound insulation reduces noise passing between letting rooms, floors and neighbours. For a house in Plymouth we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately. Plymouth has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Plymouth?
Sound insulation in Plymouth 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.
