"Booked CEC to upgrade my consumer unit. Great, responsive communication before the job. They arrived on time, finished early, cleaned up and even did an extra job I asked for at the last minute free of charge. Would definitely recommend."

"Daniel was very polite and turned up on time for both the estimate and to do the job. He fitted a new kitchen light and a bathroom extractor fan. He explained the whole process and was professional and tidy throughout. He was quick, efficient and very reasonable. Would definitely recommend."

"Daniel was polite and punctual, and kindly agreed to reschedule when we could not make the date we initially agreed. He completed the job (hanging lights) to a high standard, and made sure that everything was done according to our preferences (height, placement, etc). Would enthusiastically recommend."
