Our Core Values and how we started

Our Story

From knocking on doors to becoming one of the South West’s leading installation and maintenance firms.

Driven by innovation, precision, and speed, we launched GRM Group with a mission to deliver high-quality construction projects faster than ever before. By combining smart planning, cutting-edge technology, and a highly skilled team, we’ve turned months into weeks and sometimes weeks into days.

Founding of GRM Group

GRM Group was founded in the wake of the COVID-19 pandemic by Lee Jones, who set out with nothing but tools, determination, and a vision to build something meaningful. What began as a small maintenance business—built door by door, job by job—quickly gained momentum through hard work and reputation.

Lee partnered with Luke Carter, who became a co-owner and brought with him a wealth of over 25 years of experience; from starting as a trainee estimator/surveyor at just 16, to becoming a qualified building/Quantity surveyor with a major national housebuilding firm. Lukes’s expertise introduced structure, efficiency, and long-term strategy—helping transform GRM from a local operation into a growing force in Bristol’s construction and maintenance industry.

2022-2024

The Expansion Of GRM

Lee’s first job was in a Bristol property where he crossed paths with Jensen Mannings, a skilled electrician launching his own career at the time. The two worked together on countless projects over the following years, with Jensen handling nearly all of GRM’s electrical work. In 2024, Jensen officially became a director and shareholder, solidifying his role in the company’s leadership.

Current Day

By 2025, GRM Group had expanded far beyond its original maintenance roots. With the addition of scaffolding services, along with ongoing work in electrical contracting, general construction, and property maintenance, GRM had become a comprehensive, multi-trade contractor—trusted by homeowners, landlords, and developers alike.

GRM Group has grown through grit, reputation, and a dedication to high standards. From small maintenance jobs to large-scale installations, we take pride in delivering reliable, professional service at every stage.
