If a previous certificate exists, consumer unit upgrades for hmo landlords usually starts by checking whether it still reflects reality. About 7 miles from Cardiff, Caerphilly sits inside our standard patch — we're regularly in Cardiff and Newport on the same fixed-price model. Caerphilly sits inside the area we work daily, so a follow-up visit is not a logistical problem if one is needed. It is the difference between a fixed price and an estimate.
Property in Caerphilly varies street to street, so the honest answer to "what will it cost" is that it depends on fixed price at quote stage — checkable in under an hour. Nothing about it is unusual for property of that age. Consumer unit upgrades for hmo landlords is one of the more commonly misquoted jobs, largely because nobody tests before pricing it.
