Searching "consumer unit upgrades hmo Mountain Ash" from a Mountain Ash address usually means you want a straight answer before you want a salesperson. 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. If the property is tenanted, the visit is arranged around access rather than around us, which usually means confirming times with whoever holds the keys. Which is why the schedule of results is worth reading, not filing.
If you have had conflicting advice, it is usually because someone quoted without checking cable routing planned around mixed. Two electricians looking at the same readings tend to agree. It takes minutes to confirm and saves hours later. Every consumer unit upgrades on a hmo enquiry we take from Mountain Ash starts in the same place: what is the installation actually doing right now?
