Broad Oak Group is one of the UK’s leading providers of domestic decarbonisation and retrofit solutions, delivering large-scale energy efficiency improvements across private homes, housing associations, and local authority portfolios. With more than 25 years of industry expertise, a workforce of over 350 skilled professionals, and an annual output of thousands of installations, Broad Oak Group is at the forefront of supporting the UK’s transition to net zero.
Our mission is simple but powerful: to create healthier, happier homes by reducing energy bills, cutting carbon emissions, and improving living conditions for residents across the country. By combining technical excellence with a people-first approach, we ensure every project meets the highest regulatory and safety standards while delivering measurable benefits to households and communities.
As a trusted partner to government, housing providers, and private residents, Broad Oak Group operates under full TrustMark accreditation and in compliance with PAS 2030 and PAS 2035 standards. We have secured over £200 million in funding for retrofit and energy efficiency programmes over the next four years, allowing us to scale delivery while maintaining a focus on quality, safety, and customer care.
Our History and Growth
Founded with the aim of tackling fuel poverty and providing affordable energy solutions, Broad Oak Group has grown into a national operator with the capacity to deliver retrofit at scale. Over the years, we have expanded from a specialist in heating and insulation to a multi-service organisation capable of handling the full spectrum of low-carbon technologies and retrofit services.
From our early beginnings as an installer of efficient heating systems, we now deliver a full end-to-end service:
Assessing property performance
Designing whole-house retrofit solutions
Installing insulation, heating, and renewable technologies
Managing compliance and funding
Supporting residents with ongoing aftercare
This growth has been driven by our ability to anticipate changes in regulation and consumer demand. With government net zero targets now firmly in place, Broad Oak Group continues to expand capacity and expertise to meet the pressing need for large-scale domestic retrofit.
Vision and Values
At Broad Oak Group, our work is underpinned by a clear set of values that shape how we operate and how we deliver for clients and communities:
Healthier, Happier Homes – every measure we install improves comfort, air quality, and affordability for residents.
Excellence in Delivery – from first assessment to final handover, we maintain the highest standards of workmanship and service.
Collaboration – we work closely with housing associations, local authorities, contractors, and residents to ensure seamless delivery.
Sustainability – reducing carbon is central to everything we do, but we also focus on the long-term resilience of homes and communities.
Integrity – transparency, compliance, and trust are at the heart of our business relationships.
Our vision is to become the UK’s most trusted retrofit partner, ensuring every home we touch is warmer, safer, more energy-efficient, and future-ready.
The Market Context
The UK housing stock is among the least energy-efficient in Europe. Millions of homes are poorly insulated, reliant on inefficient heating systems, and costly to run—contributing to fuel poverty, carbon emissions, and poor health outcomes.
Government policy, including the Clean Growth Strategy, the Net Zero 2050 target, and funding streams such as ECO4, GBIS, SHDF, and Heat Networks, has created unprecedented demand for skilled, compliant retrofit providers. The market for domestic retrofit is worth billions of pounds annually, and the sector is projected to grow significantly over the next decade.
Broad Oak Group is strategically positioned to serve this market, with the scale, expertise, and accreditations required to deliver at both individual household and programme level.
