About Green Hat Renewables
MCS certified renewable energy installers with 15+ years of construction heritage, based in Isleham at the heart of East Anglia.
Built on Construction, Powered by Renewables
Green Hat Renewables was born from a simple belief: the people who install your renewable energy systems should understand buildings as well as they understand energy. With over 15 years of construction experience, we bring a level of structural knowledge and workmanship that sets us apart from pure-play energy companies.
Based in Isleham, Cambridgeshire, we are genuinely local to the communities we serve. Our team lives and works across East Anglia, covering Norfolk and Suffolk too. We understand the specific challenges and opportunities of the region — from Fenland farm buildings to Cambridge conservation areas to Norfolk coastal properties.
Every installation we complete is MCS certified, ensuring our customers can access all available government incentives including the Smart Export Guarantee, Boiler Upgrade Scheme, and 0% VAT on energy-saving materials.
Expert Knowledge Across Every Discipline
Unlike companies that subcontract to separate trades, our in-house team covers every aspect of a renewable energy installation. This means fewer delays, better coordination, and a single warranty covering all work.
Electrical Engineers
NICEIC qualified electricians handle all wiring, inverter connections, consumer unit upgrades, and grid connections for solar, battery, and EV charger installations.
Heating Engineers
Gas Safe registered and heat pump certified. Our heating team designs and installs air source heat pumps, underfloor heating systems, and cylinder upgrades.
Roofing & Structural
Our construction background means we assess roof integrity, weatherproofing, and structural loading before any solar or insulation work. No subcontractors needed.
Energy Assessors
Qualified assessors conduct every site survey, calculating energy demand, system sizing, and projected savings using industry-standard modelling software.
MCS Certified
Full Microgeneration Certification Scheme accreditation for solar PV and heat pump installations. Your gateway to government incentives.
RECC Member
Renewable Energy Consumer Code membership ensures you are protected by the highest consumer standards in the industry.
Gas Safe Registered
Gas Safe registration enables us to safely disconnect existing gas systems and install complete heating solutions.
