  • Polite, knowledgeable electricians who do a great job

    10Verified Review

    Recently had a number of jobs including moving electrical sockets, installing a complicated pendant light chandelier and installing new plugs. Marlowe did a fantastic job and is always polite, helpful and knowledgeable taking time to answer all our questions as well as ensuring the job is done well. Many thanks!

  • Fitting a replacement hob


    Marlowe was very polite and professional, he was a bit late, but I was informed that he was on his way with regular checks and updates. Overall installation went really well and the new hob is working perfectly.

  • New fuse box and EICR review

    10Verified Review

    I discussed my requirements with Dave in advance and he advised on the best unit to meet our needs now and in the future when we install AC and then Marlow installed the unit and tested everything including finding a tricky fault in our socket system. Really great work.

    This is the second time I have used Certified electricians and once again they have been excellent. David provided a prompt and competitive quote for the EICR. Marlowe carried out the inspection and the job was completed within the hour. Extremely efficient process. Highly recommended.

  • Downstairs rewiring including kitchen

    10Verified Review

    Certified Electricians did an excellent job on my downstairs rewiring and kitchen appliance electrical installation. Two new circuits were needed: kitchen ring and supply to microwave combo plus oven. Sensible discussion of location of services/sockets I needed. Fitted in with the rennovation work which was being completed. The wiring quality was meticulous. Always turned up on time and able to work around snags thrown up by the building work. Supplied NICEIC Electrical Installation Certificate, promptly recognised by the local council in respect of the downstairs work for total peace of mind.

We are your local trusted electricians, get in touch to discuss how we can help or request a free quote.  

David Smallwood the owner and head electrician established Certified Electricians London Ltd in 2014 as he could see 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 over 20 years of experience was getting 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 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 something went wrong or when trying to sell.   

Due to repeat customers, 5 star reviews and recommendations from happy customers, Certified Electricians London Ltd has continued to grow and 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 local highly skilled electricians that are all NICEIC registered. All our 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 leave your premises clean and tidy.  

Our customers are important to us and we take customer service very seriously. We provide a service that is honest, trustworthy with fair and transparent pricing. Our customers are never an afterthought we want to keep our customers 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 South East and East London areas but for bigger projects this sometimes extends to the Greater London and Essex areas.

If you require further information or a quick free estimate please get in touch. Further information on us and our services can be found here http://www.certifiedelectricians.london.
