Company info

Covid 19 - We are observing all safety measures recommended by the Safety Council for contractors on property.
David Smallwood the owner and main electrician established the business in 2014 as he could see that there was a serious lack of professional electricians and businesses that were serving home and business owners. Some of the poor workmanship and electrical hazards he had witnessed in his near 20 years of experience seems like it has only gotten worse. Unqualified electricians working in the U.K has become a bigger and bigger problem. Contractors falsely claiming to be NICEIC regulated is more common than ever and unskilled builders installing electrics as part of their ‘service’ has become more commonplace. Sadly customers are all too often finding themselves to their surprise, that they have been left with unsafe homes or businesses that they had thought complied with U.K Building Regulations not insured for purpose. This has proved costly when the worst arrived or when trying to sell.    

In the last few years, David has made serious progress in establishing Certified Electricians London Ltd as a business that can be trusted to provide the level of safety and service you should rightly expect. We prefer to sleep well at night. We only employ the highest skilled electricians that are all NICEIC registered. All works are insured and are covered by our 12-month guarantee on workmanship. We notify all notifiable works promptly to local building control authorities and certification is provided to all who requests it. All our electricians are checked, arrive in smart company uniform, are always polite and well mannered and will take the best possible measures to leave your premises as clean and tidy as possible.   

We realised that unless we could provide a service that was always honest, trustworthy and as clear on pricing and time-scales for work as possible, we wouldn’t last five minutes. Our customers are never an afterthought we prefer to try to keep you for a lifetime. This philosophy has served us well so far and we don’t intend on changing it. 

Should you be a homeowner, business or landlord we can provide for all of your electrical installation/maintenance requirements. We cover the whole of the Greater London area and the boundary within the M25.
