A commercial to HMO conversion turns space that was never a home, such as upper floors over shops or small office buildings, into shared accommodation. For a house in Swansea we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately. Swansea 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 Swansea?
The rules below are the Wales-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Swansea before we price.
- Mandatory licence for HMOs with 3 or more storeys and 5 or more people in 2 or more households; Wales did not adopt England’s 2018 change.
- More than 6 sharers is a sui generis HMO and needs planning permission; councils such as Cardiff apply concentration limits.
- Building regulations cover structural work, partitions, drainage, fire-resisting construction and electrics; confirm with building control whether the conversion is a material change of use.
- Fitness for human habitation rules require mains-powered, interlinked smoke alarms on every storey and CO alarms where there is a gas, oil or solid-fuel appliance.
