We are asked about kitchen & bathroom upgrades in Pontypridd most weeks, usually after something has changed at the property. Earthing arrangement (TT vs TN-S vs TN-C-S), main fuse rating, R1+R2 and Zs readings, RCD timings — every number on the certificate is one we actually measured on the day, not pre-filled. Anything we recommend is tied to a specific finding rather than to a general principle. Most Pontypridd visits settle this within the first hour.
Owners often ask whether this can wait. Sometimes it can, and where sockets, isolators, downlights, LED strips and feature lighting is the only finding we will say so plainly. Older installations around CF37–CF38 show this more often than newer ones. If a previous certificate exists, kitchen & bathroom upgrades usually starts by checking whether it still reflects reality.
