 Trustindex verifies that the original source of the review is Google. Dan and his team have completed many electrical jobs over the last 4-5 yrs for us, from small electrical changes to full rewiring etc.
They are always accommodating, very professional in approach, work to a high standard and leave areas clean and tidy. Highly recommend.

 Trustindex verifies that the original source of the review is Google. Very impressed with this company. Enquired about having some outside electric sockets fitted and within 2 days they were here and the work was completed in no time. Friendly guy and great service. Would definitely recommend and use them again.
