For a house in Trowbridge we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.

Questions about house to HMO conversion in Trowbridge
Do I need planning permission to turn a house into an HMO?
It depends on the nation, the council and the number of sharers. In England, three to six unrelated sharers is use class C4, and moving from a family house is usually permitted development unless the council has an Article 4 direction; seven or more normally needs permission. In Wales a change to an HMO always needs permission, in Northern Ireland all new HMOs need it, and in Scotland council policy decides. We check the address before drawings start.
