Our History

Gratte Brothers Limited was first registered in 1946 by Derrick and André Gratte, as an electrical contracting business based in Knebworth, Hertfordshire. Shortly thereafter Derrick Gratte left Knebworth to establish the London branch of the company in Red Lion Square, Holborn.

The post war years were challenging as rationing was still in place and Department of Works permits were required to purchase materials, which were only available for essential works. As these restrictions eased the electrical contracting business flourished.

In 1948 the Knebworth branch secured its first commercial catering equipment maintenance contract for a local County Council. The expertise acquired in maintaining commercial catering equipment encouraged the company to expand this service in the early 1960s to include the supply and installation of commercial catering equipment.

The late 1960s saw Derrick’s sons, Martin and Ian, join the company at around the time the company achieved £1 million turnover for the first time in 1967.

In 1968 the electrical contracting business won its first overseas contract: the Tropo Scatter Satellite Station at Jebel Ali, United Arab Emirates for Cable & Wireless. The company won a major subcontract from Entrepose SA at Bu Hasa UAE and a series of projects were carried out in the Middle East where the company maintained a presence until 1985.

The 1970s saw the establishment of a separate design division, Davis, Willis and Associates Limited to further enhance the services offered.

Mechanical systems was also added to the business’s portfolio of services with a number of successful partnerships being forged with mechanical contractors.

Identifying the increasing importance of the developing electronic security systems market in the early 1990s, Gratte Brothers formed its own security systems division which in 1994 became a stand-alone operating company, Gratte Brothers Security Management Limited.

By the late 1990s Gratte Brothers decided to offer mechanical services in-house and this was achieved in July 2000 with the acquisition of A G Manly Group Limited, an established family owned mechanical services contractor.

Gratte Brothers celebrated its 60th Anniversary at Somerset House in September 2006, when clients both old and new joined in the festivities.

From small beginnings as an electrical contractor, started by two brothers in the post war years, Gratte Brothers has now become one of the leading Building Services Contractors in the UK, whilst still remaining a family owned business.
