Whether this is urgent or simply overdue, the sequence for consumer unit upgrades for cafés & restaurants does not change much. The point of a proper test is that the result is repeatable by anyone else with the same instrument. Which is why the price follows the test rather than the other way round.
Age alone does not condemn an installation. Plenty of older Newport wiring tests perfectly well; some newer work does not. 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 for cafés & restaurants deserves more than a quick look.
