Our History

From small beginnings as an electrical contractor business 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 proudly remaining a family-owned business.

1940s

Gratte Brothers First Registered

Gratte Brothers Limited was first registered on 22nd May 1946 by brothers Derrick and André Gratte as an electrical contracting business based in Knebworth, Hertfordshire. Gratte Brothers was started with a capital of £100, a sum equivalent to 20 weeks’ wages for a skilled tradesperson at the time.

Shortly after, Derrick Gratte left Knebworth to establish a London branch of the company in Red Lion Square, Holborn and in 1948 expanded into commercial catering equipment maintenance, working for Hertfordshire County Council.

1950s

Business Expands

It didn’t take long for our London branch to outgrow the Knebworth operation by acquiring major blue chip clients in the retail and expanding aviation sectors. A number of employees were recruited in this decade who would be promoted to senior roles within the business and remain with Grattes for the rest of their working lives.

Meanwhile, a refrigeration department was set up to support the catering equipment contracts being undertaken by the Knebworth branch.

1960s

The Second Generation

Martin and Ian Gratte, Derrick’s sons, joined the London Headquarters (by now located in Wicklow Street WC1, having outgrown its original premises) as the 1960s housebuilding boom provided residential work opportunities for the company, and turnover reached £1,000,000 for the first time.

Back in Knebworth, Gratte Brothers expanded its services to include design and installation works for catering equipment (to complement the maintenance service already offered) and a dedicated commercial catering equipment division was established.

1970s

New Ideas

Martin and Ian Gratte were appointed to the Board, bringing new ideas as international work continued to grow.

By the late 1970s, Design and Build contracts were commonplace for both M&E and Electrical only work so Gratte Brothers established a separate M&E design division, and we added a mechanical building services capability to our portfolio of services.

1980s

Largest M&E Contract to Date

We won the largest M&E contract to date (£250,000 to provide building services to the Chinese Embassy in London) in the 1980s.

Ian Bass, Derrick’s son-in-law, was appointed Financial Director as turnover exceeded £13m. Gratte Brothers was flourishing in international and retail M&E works and the evolving commercial catering business was contributing significantly to the turnover.

1990s

Relocating to Regents Wharf

Having outgrown Wicklow Street, we relocated to Regents Wharf, N1 (where our London HQ is still based) and we completed our first data centre project.

We also registered a separate commercial catering equipment company, known today as Gratte Brothers Catering Equipment Limited and an electronic security management company, Gratte Brothers Security Management, as subsidiaries of the Gratte Brothers Group.

2000s

Over 100 New Staff Join

The 2000s saw Gratte Brothers acquire a mechanical services company, welcoming over 100 new members of staff to our business. This decade also saw the establishment of an M&E Maintenance division, now known as Gratte Brothers Building Services Maintenance Ltd.

By this stage, Stephen Gratte (Martin’s son) and David Gratte (Ian’s son) had also joined the business, establishing Gratte Brothers’ third generation of expertise.

2010s

The Third Generation

In the early 2010s, Gratte Brothers Security Management Limited flourished and today remains located amongst three offices; our London HQ and our Belfast and Warrington offices.

The M&E division of the business also secured a number of high-profile framework contracts in this period, and by this time, had developed its own Principal Contractor capability.

In 2016, we celebrated our 70th Anniversary. Stephen and David were joined by Chris Bass, a third Grandson of Derrick, and all three were appointed to the Group Board.

2020s

£250+ Million Turnover

As of 2022, David Gratte, Steve Gratte and Chris Bass took on operational roles at Group level to become Group Managing Director (David), Group Risk Director (Steve), and Group Sales Director (Chris). This development makes them the third generation of the Gratte family to take control of the business.

2023 saw the Group undergo a significant update to its brand identity. Retaining the charm and familiarity of the original brand, a few tweaks were made to reflect the brand we are so proud of today.

As a Group, this decade also marks the milestone achievement of surpassing £250million in turnover: a testament to the incredible dedication of our teams.
