Totally professional, highly responsive and efficient
Customer Service
We needed some lighting replaced in our kitchen plus a couple of other small jobs (new socket, fit wall lamp). Previous attempts by another electrician to sort out the lighting had failed and so we were looking for someone who had the expertise and knowledge to provide advice and guidance. Rob listened carefully, discussed our requirements (we had several email exchanges) and came up with different options at a reasonable price. He clearly knows what he is talking about and where to source the right materials. Once a solution was agreed upon, Rob arrived precisely on time and got straight on with the job. He worked efficiently and tidily and minimised disruption to those of us who were working from home. We are delighted with the result. We have already booked him for another job we have been wanting to get done for some time. Rob is also very personable. Highly recommend.

A competent & efficient professional
Customer Service
David carried out three separate pieces of work in our house. He re-routed the main telephone/internet cable, carried out an electrical safety survey and did various remedial work including the replacement of an old consumer unit. All done with great efficiency and skill, excellent communications and time-keeping and friendly good humour. Prices within 'Which?' guidelines.

A trusted electrician!
Customer Service
I asked Rob to move and replace a security light at front of house which was undertaken professionally and efficiently. The estimate was reasonable and the job undertaken at the time and date agreed. The only reason I have given 4 stars for value is that it was reasonable but not exceptional value. Rob was cheerful, efficient and professional - not all characteristics found at any one time in some trades! I will have to wait for darker nights to find if the new light does what it should but I am pretty certain it will. In any event Rob has stated if required he would come back to adjust. Really happy at finding a high quality dependable electrician locally.

Practical and imaginative
Customer Service
Rob Long of David J Long Ltd replaced wall lights, and fitted extra new ones, in my elderly mother's lounge. His approach was both practical and imaginative as he worked round the physical restrictions of her second floor flat. The resulting set up was visually attractive, as well as involving minimum disruption to her existing decoration - and all to budget.
