"Martin & Callum done a full house rewire of a 3 bedroom house, where the electrics were over 50+ years old. They were very professional throughout and explained everything to me in detail. Both were really polite and kept the place tidy and always turned up on time. The rewire was done in 4 days I would highly recommend M&J Cullen Electrical Contractors"

"Martin and Callum are excellent. Full rewire of a (very untidy!) terraced house which hadn't been touched electrically for around 60 years. I'd recommend M&J Cullen Electrical Contractors with no hesitation whatever."

"Martin and Callum carried out a full rewire of our property to an exceptional standard. Everything was explained in detail prior to starting and throughout, they really are true professionals in what they do and their attention to detail is exceptional. They are both polite, courteous, arrive on time and their attention to detail and cleanliness is second to none. Absolutely outstanding company we would highly recommend."
