At Broad Oak Group, we are committed to creating healthier, happier homes and communities across the UK, delivering large-scale retrofit and decarbonisation programmes that improve energy efficiency, reduce carbon emissions, and tackle fuel poverty.
Broad Oak Group is a Tier 1 retrofit contractor with over 20 years’ experience delivering energy efficiency upgrades and whole house retrofit solutions across the UK.
As one of the UK’s leading PAS 2035 retrofit contractors, we work in partnership with housing associations, local authorities, private landlords, businesses, and homeowners to deliver fully compliant retrofit programmes at scale.
With over 350 directly employed specialists, we provide the in-house capability required for large-scale delivery, ensuring programme control, compliance, and consistent quality across multiple regions.
Our focus is simple: to deliver high-volume social housing retrofit and property improvement programmes that meet funding requirements, achieve measurable performance outcomes, and support the UK’s transition to net zero housing.
End-to-End Retrofit Solutions, No Delays
Broad Oak Group delivers the full PAS 2035 retrofit journey, providing end-to-end whole house retrofit services from assessment and design through to installation, quality assurance, and completion.
Our directly employed teams carry out:
-
whole-building retrofit assessments
-
retrofit coordination
-
PAS 2035 compliant installation
-
quality assurance and post-install inspections
By delivering the majority of works in-house, we reduce reliance on subcontractor supply chains, maintain full programme control, and support faster mobilisation across high-volume projects.
This ensures clients achieve consistent delivery outcomes, while residents benefit from warmer homes, reduced energy bills, improved EPC ratings, and long-term carbon reduction.

​
Our services include mould and damp treatment, kitchen and bathroom replacements, general repairs, extensions, and property adaptations, supporting landlords in maintaining safe, modern, and compliant homes.
​
This integrated approach allows us to deliver retrofit alongside wider building improvements, reducing disruption for residents and improving long-term asset performance.
