This is a practical page about consumer unit upgrades on a period flat in Ebbw Vale — no stock photography claims, no invented statistics. We handle the letter chain if needed. We do not upsell a full replacement where a component is at fault, and we do not patch something that has reached the end of its life. Anyone testing properly will reach the same conclusion.
The practical question for a Ebbw Vale property is not what usually happens, but what this installation actually shows when it is tested. It rarely changes the price, but it does change the plan. The Ebbw Vale version of this job is shaped by the local housing: valley terraces in Beaufort and Cwm.
