Whether this is urgent or simply overdue, the sequence for consumer unit upgrades on a 1930s semi does not change much. That local pattern is baked into the quote, not discovered on the day. Access is part of the job here. Neath properties vary from open loft space to boarded conversions, and that changes how long a visit takes. Which is why the price follows the test rather than the other way round.
The point of a proper test is that the result is repeatable by anyone else with the same instrument. The regulations are specific about it, so there is little room for opinion. If the property has been altered, extended or let out, consumer unit upgrades on a 1930s semi deserves more than a quick look.
