You can spend a lot on consumer unit upgrades on a edwardian semi or very little. Which one is right depends on measurements, not on the quote. On a Edwardian semi you should expect us to flag: front-bay window seats hiding original single-insulated conductors; porch lighting on a spur off the hall circuit with no dedicated CPC; cellar or under-floor damp affecting the incoming supply. Owners in Tredegar often ask whether this is a repair or the start of something bigger. Testing answers that; opinion does not. It takes minutes to confirm and saves hours later.
There is a version of this job that is quick and a version that is not, and the difference is almost always fixed price at quote stage, calibrated to c.1901–1918 construction. A short survey tells us which one your property is. It rarely surprises us; it often surprises the previous quote. Consumer unit upgrades on a edwardian semi sits somewhere between routine and urgent depending on what the property is doing right now.
