J. O'Connor Mechanical & Electrical Contractors

About Us

Established over 25 years ago, J O'Connor operates nationally, with a focus in the South East and Home Counties. Our reputation throughout the Public Sector, Commercial and Large-Scale Private markets is due to our experience, conscientiousness and the personal attention that all clients receive from our dedicated, specialist teams.

We have worked with the Social Housing sector since the 1990s and our Contract Gas Services ensure families remain warm and safe in around 10, 000 properties per year across the UK. We take pride in our 100% success-rate with CP12 certification.

In addition to our industry accreditations (NIC EIC, Gas Safe, ISO9001, ISO4001) J O'Connor Engineers have Advanced Level certifications to install Central Heating from preferred suppliers such as Vaillant, Glow-worm and Worcester. We are proud to be working with the Government, providing both heating and plumbing services, under the Decent Homes Initiative. Our 24/7 Out of Hours Response Teams understand how vital our service is to all tenants, particularly those who are more vulnerable.

J O'Connor's Commercial Heating Team undertakes full design, installation and maintenance of £500k+ contracts. Our commercial Plumbing teams specialise in the installation, testing and maintenance of commercial pumps and plant.

Over the past 25 years, our reputation for Electrical Services has grown within the Commercial and Private Residential sectors. J O’Connor Ltd is the name behind high-profile retail fit-outs, refurbishments and new builds. We carry out high-standard programmes of NIC EIC accredited testing. Such is the growth of our Electrical Services that we also provide Facilities Management for residencies in excess of 500 units, providing a one-stop-shop for all mechanical and electrical services including lighting, boilers, alarms, heating, plumbing and door entry.
