YORK-BASED Green Building Renewables has bought a tenth company, giving it an annual turnover now exceeding £40m.

Crawley-based Doré Woodman has joined Green Building Renewables’ nationwide network of renewable experts, allowing the company to expand further into Kent, Surrey, and Sussex.

Since 2021, Green Building Renewables has increased its turnover more than tenfold from £3m to over £40m. At the same time, staff numbers have risen from 18 in its York office to over 200 across its 14 regional offices in England.

Doré Woodman’s acquisition and Green Building Renewables’ further expansion into the south and home counties is part of the company’s continued strategic vision to extend the benefits of solar energy and low carbon heating to as many local communities as possible nationwide.


The company aims to be the largest installer of domestic renewable technology by 2025 with a turnover of £100m.

Managing director of Green Building Renewables, Chris Delaney said: “Our tenth acquisition and surpassing the £40m turnover mark is a double milestone for the company and a great start to the year. Everyone within the business can be extremely proud of our achievements in the last two years.

“We have grown our reach and expanded our coverage across England. Our ambitions for 2024 are even bigger as we aim to have full coverage of England. We welcome Ben Freeman and the team at Doré Woodman to ours.”

Green Building Renewables offers a range of renewable technology solutions through its growing network of local energy experts. It provides air and ground source heat pumps, underfloor heating, solar PV, EV charging, and battery storage.

Ben Freeman, founder of Doré Woodman, said on the deal: “From the outset of our discussions, it was clear that Green Building Renewable is creating something unique. Its model of a nationwide network, based on local installers, is exactly what this market needs and aligns with our own core-beliefs“Unlike conventional heating systems, heat pumps require extensive design, installation and commissioning capabilities coupled with a supportive, customer-driven mentality. Our full-system approach links the many different renewable systems into one bespoke solution, thereby ensuring a streamlined, efficient process to deliver the perfect outcome and a best-in-class customer experience.”

Doré Woodman serves residential clients in Kent, Surrey and Sussex and specialises in heat pump installations. The business has focused on self builders, SME developers and retrofit installations of heat pumps, solar PV, battery storage, MVHR and underfloor heating and aligns perfectly with Green Building Renewables’ model, which is built on providing regional expertise and cutting-edge technology, which is only installed by local in-house engineers.

Green Building Renewables recently appointed Chris Joubert as its new Merger and Acquisition Director to lead further growth of Green Building Renewables through the strategic acquisition of reputable renewable installation companies across England. Chris said, “Doré Woodman is the perfect example of the calibre of company that we want to join Green Building Renewables and to help expand its network. While I can’t take responsibility for bringing this acquisition on board, it is a perfect blueprint for the type of business I will be looking for and aiming to get into the company’s nationwide network.

“I am looking forward to working alongside Chris and the team at Green Building Renewables to help reach its ambitions of becoming the largest domestic renewables installer in England and to reach its £100million turnover.”

Green Building Renewable’s network already has regional offices in York (two), and Scarborough, among others.
