Ask three electricians about consumer unit upgrades on a bungalow and you may get three answers. Ours is based on what the readings say. No wholesale "modernise everything" pitch when the existing installation is sound. This is routine work carried out weekly across CF37–CF38, so the process is settled: check cable routing planned around cavity brick, generous single-storey plan, record it, quote it, complete it, certify it. The regulations are specific about it, so there is little room for opinion.
A quote that arrives before any testing is a guess with a number on it. We do it the other way round. Which is why the schedule of results is worth reading, not filing. The starting question with consumer unit upgrades on a bungalow is always the same: what does the existing installation test at?
