We contracted Thornton Electrical to replace a very old consumer unit. Following an EICR and the initial board change, multiple RCBO devices failed in the immediate days and weeks post the installation. Whilst we were anticipating some level of nuisance tripping may occur as part of these works, this problem manifested in a series of blown fuses rather than merely tripping. After calling back Thornton Electrical several times to look at the problem, responses became slower and slower, and we lost faith in their ability to provide root cause analysis and remediation of the problem.

We called in a second electrical contractor to inspect the installation to ensure the board was safe as well as investigate the issues we were experiencing. Upon inspection they pointed out the installation lacked an SPD, in contrast to current regulations. The second contractor installed The missing SPD unit and we have not suffered any further problems with the installation since. I contacted Thornton Electrical to make a formal complaint, outlining what we believe may have transpired, noting the lack of SPD, and providing photographic evidence showing the lack of SPD in the new consumer unit, pointing out the lack of one contravened regulation.

Over several emails, there was an initial suggestion that my elderly mother was somehow to blame for not requesting an SPD device as part of the installation. They claimed to have no prior knowledge of any faults, but then subsequently admitted that they had been called back to the property several times. I requested a that Thorntons should be able to verify the claim that an SPD was supplied but not fitted by analysing the initial internal Bill of Materials to allow them to check one was specified.

This request was ignored. Future emails admitted that one should have been fitted but wasn't and that the engineer no longer worked for the organisation, in a flimsy attempt to divert from the companys overall responsibilities to ensure works are performed to current regulations. As a result, we cannot recommend Thornton Electrical.
