Our story

Green Frog Mechanical provides an all-encompassing mechanical and plumbing service for commercial, industrial and domestic projects. We have worked on a diverse range of projects throughout the UK and overseas for high-profile clients, from student accommodation blocks to colleges and schools, hotels and commercial businesses as well as the power generation industry.

By combining our mechanical and plumbing services, as well as Utilities, via our parent company Green Frog Utilities  (a fully independent gas utilities infrastructure provider) we are able to provide our customers with a one-stop-shop. This approach, with communication from the outset, reduces costs and increases efficiency and simplicity in our installations.

We understand the pressure our clients have to keep costs down and meet tight deadlines. When it comes to your development schedule, it is essential that trades work together simultaneously on-site. There is no better way to establish this than an efficient workforce that combines the expertise within a well-formulated team of project managers and engineers that understand one another needs.

Our Philosophy

Our business has been built over many years on the delivery of high-quality projects both on time and to budget. As we have grown over many years adding capability – we have tried to retain that over-arching philosophy. We recognise that large projects often can slip in the programme for a range of complex reasons. We pride ourselves on the flexibility we offer when this happens. Our internal systems mean that all of our site works are checked independently before handover – this minimises and often eliminates the need for any remedial works.

Our clients

Based largely in the West Midlands our client base has grown over many years.  It is a testament to our team and the culture we have developed that we continue to grow these relationships. By working with clients from the early stage of a project, we are able to identify both logistical and practical challenges often missed by the design team – saving considerable time and money. We work for many of the major construction companies, the MOD, large private developers, and other government agencies.

Design Services

Where required we are able to offer clients a complete design and build service.  Our in-house engineers are supported, on larger projects, by two specialist design teams. Through this partnership, we are able to frequently deliver very complex projects. 


What Our Clients Say

John Joy

Operations Director - Torsion Engineering

We have recently worked with GFM on a 220 room commercial residential new build development in the centre of Sheffield. GFM quickly developed a detailed cost to install domestic services, sanitary ware and plantroom, Lee was very thorough in his pricing process and was happy to point out any inconsistencies encountered to avoid confusion further along the project. The project handover requirement meant a shorter than usual programme and GFM were very proactive in working closely with our site team to ensure areas of work were complete to allow further trades ample time to follow on. The project was resourced adequately throughout with a more than capable site supervisor and team of installers.  It was a breath of fresh air to work with the GFM team, they have a very positive outlook and professional approach to Health and Safety delivering a quality install to ourselves and our client. With all of this in mind we have just instructed GFM as a mechanical contractor to a similar project and look forward to working with them again.

Paul Salmon

MEP Projects Manager - BAM Construct

Having worked with GFM for a number of years now I have always found them to have a professional can-do attitude with a highly skilled flexible workforce consistently demonstrating this at all levels.  Quality of workmanship has never been in question leading to continued repeat business across a wide range of projects from schools to commercial developments ranging in value from 100k to over two million pounds delivered on time and within budgetary constraints.  I would have no hesitation in recommending GFM to any potential clients and look forward to working with them for many years to come.

GFM have been working in partnership with the Dodd Group for the last 10 years. They have completed Mechanical Works for various local Authorities which has included School Plantrooms, kitchens and classrooms. Works in the main are carried out within the school calendar holidays for that local authority with immovable deadlines. Projects have been completed both on time and within budget. Overall the team at GFM are competent and efficient partners to work with and always go the extra mile to ensure projects are completed on time and budget with the highest quality of workmanship.”
