Consumer unit upgrades on a period flat comes up regularly on Tredegar properties, and the honest answer starts with what the installation actually shows. On a period flat you should expect us to flag: sub-main tails routed through communal areas — freeholder consent needed for CU work; communal lighting on a separate meter, not always tested with the flat's EICR; old landlord's supply feeding hallway heaters or emergency lighting. Most enquiries about this start with a symptom and end with diary planned for the access constraint. We would rather set that expectation now than on the day. In practice that means checking diary planned for the access before anything is replaced.
A quote that arrives before any testing is a guess with a number on it. We do it the other way round. It is written into the report either way, so nothing is hidden. This page covers consumer unit upgrades on a period flat for property in Tredegar and the surrounding NP22 postcodes, in the order the work happens.
