Outstanding service
Customer Service
Following a series of falls I was advised by the occupational therapists that I would need a stair lift. I contacted David to see when an additional power socket could be installed he came to see what needed to be done and due to the urgency did the work straight away. David has done electrical work for me over the past few years and is always very professional in carrying out the work.

Honest & Reliable
Customer Service
David and his brother Rob are great guys. When we were building our extension with an office their work was of the highest quality. They are friendly, flexible and easy to get on with. We have had them out four times so far. We couldn't recommend them highly enough.

Rob was friendly, took the time to get to know what we wanted and even did an extra job we hadn't prepared him for. He charged us a very reasonable price and we couldn't recommend him higher.

Exterior Light Repair & Periodic Test
Customer Service
We contacted David J Long regarding a problem with an exterior light & for a periodic test of our house wiring. We received a very prompt reply and visit from Rob, who provided an estimate for the remedial work the same day. The repair and test was carried out, with the minimum of inconvenience to us, & the periodic test highlighted some issues with our system, the minor issues were however fixed by Rob at the time of the test with no additional charge to us. An estimate was provided (again the same day) for the additional works required to rectify our electrical system, together with an explanation of what was required. Rob has been a pleasure to deal with, and carried out the works in a courteous and professional manner, having also answered further queries we have had very promptly. We will therefore be using David J Long Ltd for any future electrical works we may have, and have no hesitation in recommending their services.
