About Us


Initially established as a sister company to London based Gale & Daws, GDE Ltd. has now branched away as specialist electrical contractors.


Over the years we have undertaken commercial, domestic, industrial developments including London’s major regeneration, social housing and commercial projects.


GDE have over fifty years combined experience working for major contractors operating in London and the surrounding areas.

Our aim is for our highly experienced estimators to offer competitive pricing whilst offering a professional service and installing high quality equipment.

We have established close relationships with various suppliers and manufactures as we understand the need for a personal approach.


Our strategy is to fulfil our clients' needs, not only in the quality of our work but to have a flexible approach by responding in a timely manner and being committed to providing exactly what is requested.
