We take a steady number of consumer unit upgrades on a hmo enquiries from Tredegar each month, and the pattern is fairly consistent. Materials and methods we spec on hmo conversion work: RCBO-per-circuit CU so one tenant fault doesn't kill the house; BS 5839-6 Grade D interlinked alarms; emergency lighting on escape routes. A quote that arrives before any testing is a guess with a number on it. We do it the other way round. The paperwork explains it in the same words we would use on site.
Most enquiries reaching us from Tredegar arrive after something has already been tried. Starting from measurements rather than the previous attempt saves time. Around NP22 it is priced against your HMO's specific that decides how long the visit takes. There is a short version and a long version of consumer unit upgrades on a hmo. The short version: test it, then decide.
