What the public record says
Highlights
"I made an enquiry in regards to a media wall set up for my new home. A friend referred me to KA Contractors and they did not disappoint. They came over to do a free estimate and confirmed everything with me including the designs and materials. It took KA contractors 2 days to complete my media wall alongside the electrical aspects of it. Housekeeping was important to me and they made sure there was not a speck of dust anywhere in my living room. I cannot express my gratitude for KA contractor for turning my idea into a reality. 5 star work for a 5 star contracting company. I will most definitely use you guys again for future works. Thanks Kayan."
"I have retained Kay Electrical several times, in several properties, for various jobs from the simple to the complex. Each time they have remedied the issue where others before them have failed. All members of the team have been professional and polite and they, and their management, have been a pleasure to deal with. I have used many electricians over the years and Kay Electrical is the only company I would recommend wholeheartedly."
"The service from Kay Electrical has been the best I have come across in 30 years of working in the building industry. Their level of expertise is amazing and always find a way to tackle any issue you may be faced in the electrical sector. They have carried out numerous rewire's of domestic houses/flats and also commercial premises for me and have installed fire alarms and emergency lighting in common parts of blocks of flats/hmos. No job is too big for them and their professionalism is very hard to come by nowadays. I will continue to use their services and would highly recommend!"

At short notice they very helpfully came and connected up my new oven in time for Christmas
I've been using Kay Electrical and Security since 2014 and they have done all of my electrical work at two properties over the years including a full rewire, alarm install and servicing. Most recently I used them for servicing my alarm and relocating proximity sensors. I couldn't recommend them enough. I've probably had 10 jobs done over the years and perfect every time. Never had an issue with anything they've installed.
Kamel and his team were excellent from start to finish. Friendly, open and honest discussing options, great communication and work done on time and on budget. Definitely intend to use again in the future and wouldn’t hesitate to recommend.
Excellent service. Reliable and friendly would highly recommend them.
During the Electrical Safety Survey of our flat Kay Electrical identified a problem with the old fuse board. Unfortunately it had to be replaced in order to comply with the latest safety regulations. They were able to do the work a few days later. It was done very promptly and efficiently, just like other works carried out by them on previous occasions.
Kay security provided excellent advice and service as well as value money. They were extremely knowledgeable, reliable and professional. Nothing was too much trouble.
Kay electrical were efficient and polite. They completed the job very well and were extremely happy to come back when a small adjustment was needed I would thoroughly recommend them
