Read moreThey gave a fast response to my initial contact and the lady on the phone was very good and quickly made an appointment that suited me. The tradesmen arrived on time exactly as promised. The job was complex and challenging and required a high level of expertise in trouble shooting. Finding the fault quickly they rewired the damaged cable and on completion they cleaned up. The two men who did the job were very professional and communicated with me at all stages. They exceeded all my expectations and I have no hesitation in recommending O'Brien Electrical for any work electrical work you may have. I would definitely use them again. Their pricing is competitive

As always the work was done quickly and efficiently, the boys always clean up after themselves. Very mindful of our busy practice and patients. Nothing is ever too much trouble. Thanks
