Every full property rewires on a hmo enquiry we take from Tredegar starts in the same place: what is the installation actually doing right now? On a HMO you should expect us to flag: communal-area lighting on a shared circuit with an individual room — a licence-fail issue; BS 5839-6 Grade D interlinked alarm system with mixed-vintage sensors; no emergency lighting on the escape route. Owners often ask whether this can wait. Sometimes it can, and where fixed price at quote stage, calibrated to converted house is the only finding we will say so plainly. Around NP22 it is the single most common reason a job runs long.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. For valley terraces around Sirhowy and Georgetown that detail matters more than it does elsewhere. Full property rewires on a hmo touches safety, paperwork and cost, and the three do not always point the same way.
