This is a practical page about consumer unit upgrades on a bungalow in Tredegar — no stock photography claims, no invented statistics. On a bungalow you should expect us to flag: old CU in a hallway cupboard, still plastic split-load; no SPD, no per-circuit RCBOs; extension added over the years with a mixed-vintage sub-board. Where the answer is to leave it alone for now, that is exactly what we will tell you. Anyone testing properly will reach the same conclusion.
Where previous work has no certification behind it, we test it rather than take it on trust. It rarely changes the price, but it does change the plan. The Tredegar version of this job is shaped by the local housing: valley terraces around Sirhowy and Georgetown.
