O’Briens Electrical Ltd is made up of a team of qualified commercial contractors in London, and a support team who make sure you get the service you need, when you need it. We are highly experienced in working with many commercial clients, including landlords, small business owners, business owners with offices, and those with large commercial spaces.

Our focus is on providing expertise and efficiency to all our clients, regardless of the size of the task. Please get in touch about any commercial electrical work you may require – we are just as happy to fit new electric sockets as we are to carry out a full building refurbishment.

The team at O’Briens are lighting specialists. We are fully qualified and NICEIC approved, so we can carry out lighting installations of all shapes and sizes. But it’s more than just this for us – we are lighting designers, using the lighting we install to tangibly improve your property. We make sure every light fitting is installed to look great, not just to function well. Attention to detail is important to us and we take great pride in our work, for example, you know that every light switch will be perfectly horizontal and ell electrical sockets will be completely symmetrical.

The commercial lighting we regularly install includes:

  • Tubular fluorescent light fixtures
  • Compact fluorescent light fixtures
  • LED light fixtures
  • Wall lighting
  • Bespoke desk lighting

Ask us for advice – we work in consultation with you. We are competent at finding solutions that will meet your needs in full.



We are experts in electric heating systems and will be able to find heating solutions for you in any part of the building – inside or outside of it.

We regularly install various electric heating systems, including:

  • Electric central heating
  • Electric patio heaters
  • Outdoor electric heating strips
  • Underfloor heating


If you are moving into a new office block or need a full refurbishment of any kind, we are available to help. There are many situations and circumstances in which you would need an electrician, from installing new lighting to wiring in appliances. Our team will be happy to schedule in the work for you. Please just get in touch so we can provide an estimate.



Please don’t think that we only take on large projects. We are a flexible, experienced team happy to take on any electrical work that our clients need. It might seem small, but not having enough sockets, or needing a new light switch, can really begin to impact on your business.

Some tasks we regularly complete for businesses include:

  • Fitting new electrical sockets
  • Fitting light switches or dimmer switches
  • Wiring in appliances e.g. ovens and stoves
  • Changing hard-to-reach light bulbs on high ceilings
  • Ceiling fan installation or repairs

We will undertake any small electrical work you need – it doesn’t have to be listed here. Just get in touch and let us know what you require.
