What Energy Saving Trust does

Energy Saving Trust is a UK-registered non-profit organisation (company limited by guarantee, no share capital) founded in 1992 following the UN Earth Summit in Rio de Janeiro. Operating from headquarters in London with a staff team of more than 300, it provides independent, impartial advice on energy efficiency, low-carbon heating, electric vehicles, and renewable technologies to UK households, businesses, local authorities, financial institutions, and devolved governments. The organisation reaches over two million people annually through phone, email, face-to-face, and digital channels, and helped 104,000 households through energy advice services in 2024/25.

The company operates a diversified service portfolio spanning digital tools (Homewise personalised retrofit planner, Home Energy Efficiency Tool, Home Analytics modelling, Energy Advice Tool for smart meter installers, Infact data insights, and Dynamic Engine technology), consultancy services (Net Zero strategy, Local Area Energy Plans, fleet decarbonisation, green finance portfolio intelligence), and government programme administration (Home Energy Scotland, Welsh Government Nest scheme, regional English programmes, Boiler Upgrade Scheme support, and Energy Redress Scheme). Distribution in 2024/25 included £152 million in loans and grants administered on behalf of governments, £9 million in identified energy saving opportunities for businesses, and 1,145 energy improvement reports for organisations.

Its business model combines government grant and contract income (primary), enterprise consultancy fees (secondary), and FCA-regulated consumer lending for interest-free EV and heat pump loans. Key institutional customers include Lloyds Banking Group, Halifax, Co-operative Bank, Danske Bank UK, E.ON, Transport for London, Amazon, Uber, Airbnb, Wiltshire Council, and Cornwall Council, alongside relationships with all four UK devolved governments. The Energy Saving Trust Foundation, established in 2014, operates as a wholly-owned charitable arm focused on youth-led climate action. The organisation is authorised and regulated by the Financial Conduct Authority (Firm Reference Number 716195), holds ISO 14001 environmental certification, and is accredited to CCA Global Standard for customer service.

Broad incumbents

• WSP: Global professional services firm with a sizeable climate, energy, and retrofit advisory practice — overlaps with Energy Saving Trust's local-authority Net Zero Consultancy and housing-retrofit engagements.
• Mott MacDonald: Global engineering and development consultancy with a substantial climate, sustainability, and energy practice advising local authorities and governments — competing for the larger corporate and public-sector mandates that Energy Saving Trust also serves.
• ICF International: Global advisory and digital firm with dedicated energy efficiency, climate, and public-sector practices — competing for the same government programme evaluation and policy research work that Energy Saving Trust delivers.

Direct peers

• Anthesis Group: Global sustainability consultancy offering corporate net-zero strategy, carbon accounting, and supply-chain decarbonisation — directly competing with Energy Saving Trust's business and local-authority advisory services.
• Carbon Trust: UK- and internationally-focused mission-led organisation providing carbon advisory, programme delivery, green finance advisory, and climate strategy services to governments and corporates — the closest direct peer to Energy Saving Trust's climate advisory and programme-administration model.

Others

• Climate Bonds Initiative: International organisation mobilising capital for climate projects via green-bond standards and sustainable finance advocacy — adjacent rather than competitive, complementing Energy Saving Trust's green-finance advisory and consumer-facing green lending activity.
