We build to the standards your council publishes and give you the certificates and drawings an inspection asks for. The licence decision belongs to the licensing authority, so we never promise approval, but we design to meet the written standards from day one.
How long does a house to HMO conversion take?
Most conversions of a three or four-bedroom house take six to fourteen weeks on site, after drawings and any approvals. Bigger layout changes, extensions or loft rooms add time.
