What We Do

Operate at optimum efficiency

Could your building be more secure, more rentable, or more environmentally-friendly?

Our team of electrical engineers serves London and Essex, installing and maintaining electrical systems and much more…

Since JR Revell started in 2012, we’ve delivered a range of mechanical and electrical services for commercial and industrial buildings all over the UK. Our M&E team can now handle projects of any size – while sticking to our original quality standards.


JR Revell is one of the fastest-growing electrical contractors in Essex. With our engineers we can manage all of your installations, including high and low voltage cabling, lightning protection, and power distribution.


Ask us to design and plan a bespoke lighting solution. We bring in specialists and manage your project, from design to completion, with seamless expertise.


Improve your building’s security: we can carry out an audit and make a plan to install security cameras, alarms and access control.


Achieving net-zero starts with monitoring your energy efficiency. To ensure your building’s running at optimum economy, we could install solar panels and storage cells or update your heating systems. We also supply metering by Rayleigh Instruments.


Don’t forget that our team provides mechanical services too. We’ll design and install your plumbing or heating, including drainage, ventilation and air-con – and we can work with your M&E consultants using their spec.


Before the emergency happens, call us. We offer planned, preventative, and reactive maintenance, to keep buildings running efficiently and avoid…


It happens. We act fast – whatever the problem, rest assured our brilliant mechanical and electrical team will get things up and running again.


But it has to be done, so leave it with us. We’ll ensure that your systems comply with the latest legislation. Call on us for EICR electrical testing or fire alarm testing and certification.

(Unforeseen problems in the project? Our M&E engineers are great at adapting to meet your goals, whatever happens.)

Yes we can…

JR Revell was founded as an electrical contractor in Essex, but has grown into a national company with an expert team. Whether you are managing a large-scale build or renovating or maintaining a commercial building, we can tick a lot off your list:
