What is a consumer unit and when should it be replaced?

Calum was requested to replace our LED porch light which had gone on the blink. New and effective unit supplied and fitted and thoroughly tested. Highly satisfied.

Calum from Keswick Electrical Services is a reliable and trustworthy professional that I would highly recommend.
He was prompt and professional in his contact with me and he did a great job with upgrading our indoor spotlights. I’m very happy with the quality of the work. Thank you.
