For tightly-packed Taff valley terraces in Treforest and Cilfynydd in particular, consumer unit upgrades on a hmo throws up a fairly predictable set of findings. That means the quote reflects real experience of this property type, not a template price. A property in Pontypridd that has never been inspected is not necessarily unsafe — it is simply unknown, and that is the part worth fixing. That is one reason our price does not move after the survey.
The practical question for a Pontypridd property is not what usually happens, but what this installation actually shows when it is tested. The alternative — ignoring NICEIC certificate, photo evidence — tends to cost more later. You can spend a lot on consumer unit upgrades on a hmo or very little. Which one is right depends on measurements, not on the quote.
