Here is how consumer unit upgrades on a 1930s semi works at a Barry address, including the parts that decide the price. That's the whole process for a Barry 1930s semi, on one page. Access is part of the job here. Barry properties vary from open loft space to boarded conversions, and that changes how long a visit takes. It gets photographed if it will be hidden afterwards.
What we are really assessing is condition, not age. Certificate at the end, delivered the same evening matters; the date on the board does not, by itself. In practice that means checking certificate at the end, delivered before anything is replaced. What matters for consumer unit upgrades on a 1930s semi is the condition of this installation, not the average condition of installations generally.
