What our clients say...

We wanted to look for a green energy solution and our architect recommended Mesh. Mesh helped us to scope out the options, develop a viable, cost-effective specification, worked with the chosen contractor and then helped us navigate the complexity of the RHI regulations to get our system registered with OFGEM. Mesh are genuinely helpful and have continued to be a great source of advice. We have enjoyed working with Mesh.

Stephen Dawson, Operations Manager, St Margaret's Church

We engaged with Mesh at an early stage on a number of projects. Their input has helped drive a holistic fabric first sustainability approach that has underwritten our co-ordinated design development and project delivery from concept to commissioning and client handover.

Mesh have been proactive in providing long-term deliverable tailored solutions focused to the specific needs and requirements of the client. This has included a full design service overseeing a number of other specialist M&E consultants and where required reviewing VE proposals which helped with the financial challenges of the package.

The team have been a pleasure to work with and we’ll be working with them again.

Adam Lansdown-Bridge, ACG Architects

How do you know what you don't know?!! This is exactly how I would retrospectively describe the commissioning of Mesh for our residential project. It is probably the best thing we have done so far on our journey to bill free living. Mesh was able to assess our project and personal circumstances to create sensible, pragmatic recommendations in a very efficient and timely manner. By taking a holistic view rather than being driven by a single dimension (ie solar, heat pump etc) we were able to consider every option.

Darren McBride

I found the report you produced and the service provided for our small pavilion extremely helpful and informative. You did a great job in explaining heating options available which helped my understanding and made it easier to discuss options with the clients. I did let everyone in our office know and circulated your report, as I think other projects might benefit from the same input or the more in-depth consultation.

Published in partnership with WorkL, this nationwide survey celebrates the country’s top employers each year, which have excelled in creating outstanding workplaces and exceptional wellbeing support. Founded in 2015 and a certified B Corporation, Mesh works across the built environment helping building owners, commercial developers, housebuilders and architects reduce energy consumption and carbon emissions for both new and existing buildings and estates. This is the second accolade that Mesh has received in the past month – it was awarded Energy Efficiency Consultancy of the Year at the South East Energy Efficiency Awards in recognition of its forward-thinking approach to low-carbon design and engineering, energy solutions, decarbonisation and regulatory compliance. The Sunday Times report highlighted Mesh’s monthly team challenges, from step count competitions to acts of kindness, which support both teambuilding and promote wellbeing. It also commended its benefits package which includes time off for charitable activities, a performance-based bonus scheme, unlimited holiday, teambuilding days and quarterly awards to recognise those living the company values.
