Welcome to Smart Energy Group. We’re passionate about making sustainable, efficient energy solutions accessible - whether you’re a private homeowner, a tenant, a business, or part of an affordable‑housing project. Our Mission & What We Do Our mission is simple: to bring low‑carbon, cost‑effective energy solutions to homes, businesses and social housing across the UK.

We specialise in energy efficient, renewable upgrades – including insulation, solar panels, and the latest in heat‑pump technology – to help reduce energy bills, lower carbon footprints, and make spaces warmer, greener and more comfortable for everyone. As part of this, we are proud to be the UK’s first accredited installer of the Octopus Cosy heat pump system. Being an accredited installer means we meet rigorous standards and it allows us to offer a trusted, future‑proof solution that’s designed specifically for UK homes and built for real‑world comfort.

Trusted, accredited and quality‑driven: We carry an extensive set of accreditations – including TrustMark, QualityMark, MCS certification, among others – meaning our work meets high standards of safety, quality and compliance. Growth driven by impact: In 2025, we were honoured to be named the UK’s Fastest‑Growing Green Firm – and also recognised as the fastest‑growing firm in Wales, based on the UK Fast Growth Index. These achievements aren’t just awards to us – they demonstrate the trust customers place in us, and the real-world difference we’re making across the country.

Who We Serve At Smart Energy Group, we serve a wide spectrum of clients: Homeowners and tenants looking to upgrade heating, improve energy efficiency and reduce bills. Affordable housing providers aiming to meet sustainability and energy efficiency standards while providing warm, comfortable homes.
