LEC Group has grown in recent years from a small group of Electrical Engineers, to a group of companies providing Electrical, Mechanical, Fire, Security & Renewable Services throughout London and the Home Counties expanding to the rest of the UK.

Large enough to use our buying power to pass-on cost savings to clients, LEC Group has also kept the high service levels you expect to receive from a small business, by providing a partnership approach that treats all clients individually, on a case by case basis.

Our team of engineers can install a wide range of Construction, Building Services and Renewable Solutions to provide a wide range of services, including funding and unique energy / cost saving.
