Electricians in Cardiff

Phone numbers for electricians covering Cardiff — EICR, consumer units and rewires. Open a profile and call the business yourself. This site does not send your job.

A consumer-unit or rewire quote should name the testing that will be left with you. NICEIC or NAPIT appears only when it is on the profile. Barry and Caerphilly on a card are not Roath. The Welsh form of the electrical notification rule applies here; this is not an English Part P form with the city swapped. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes for a sourced national range; a figure on a card is not a quote.

Notifiable electrical work in a Welsh dwelling is covered by the Welsh form of Part P. A listing here is a name and a number, not a building-control notice.

Questions before you phone

How do I find electricians in Cardiff on this list?

Cathays and Roath are bay-fronted terraces used as shared houses. Pontcanna is closer to the river and more likely to be a conservation street. Splott is a different roof and a different parking problem. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. Barry and Caerphilly on a card are not Roath. The Welsh form of the electrical notification rule applies here; this is not an English Part P form with the city swapped.

Does this page send my job to a Cardiff electrical firm?

No. You place the call. This site does not email or text anyone on your behalf.

What should the written price say for electrical in Cardiff?

HMO detection and the Welsh building notice should be named. It is not England's Part P form.

What is easy to miss before booking in Cardiff?

Bay roofs leak into the front bedroom while the main pitch is sound. A 'roof repair' that does not say 'bay' has not looked at a Cathays terrace.
