Hello My name is Samuel J Johnson and I am the proud owner of Double J Electrics. 

We are a NICEIC approved contractor and offer a friendly honest service.

All electrical work undertaken. Experienced, local and friendly electrician, fully insured with Direct line business insurance and registered with the NICEIC, keeping you safe in your home or at work.

All work is covered with the NICEIC platinum Promise for more information please visit

I take pride in my work and value every single customer, I have worked  hard to get my company in the position it is today and wish to continue to spread my good name.

I am competitive on pricing and I will always try to save my customers money on parts when possible and never undertake unnecessary work.  
I have gained my qualifications through an apprenticeship and I was nominated for 'apprentice of the year' while studying at Newbury college. I have now worked my way to owning my own company. My wife helps with the accounts so this is a family business. 

Highly recommended on various Facebook groups and within the construction community. We are looking to emulate this on Checkatrade by continuing to provide a good, honest and friendly service.

Some of these services include:

  • Fuseboard installation. 
  • Extension installations
  • Outside lighting 
  • Testing and inspecting. (Landlord certificates, Insurance satisfaction) 
  • Re-wires and circuit installation. 
  • LED lighting install. Smart lighting and switching. 
  • Nest and Hive installations.
  • Heating installation, fault finding and rectification.
  • Underfloor heating. 
  • Domestic Commercial and Industrial work all undertaken. 
  • All other electrical services.

I have experiences in working in nearly all areas of the electrical industry, from Pinewood studios working with big power supplies, providing electrical maintenance to company's and homes alike in the Berkshire area and completing large re-wires and new build installations. 

Please feel free to get in touch for a free quotation and we can organise a time to come and have a look. (If you are a little strapped for time, face time me using Facebook and show me the work you would like carried out at your convenience).
