What We Do For Providers.
We provide high-quality, PAS2035-compliant retrofit assessments and end-to-end support to help housing providers deliver successful, compliant retrofit programmes.
Who Are We?
Green Gnomes is an independent retrofit consultancy supporting housing providers and local authorities through complex, large-scale domestic retrofit programmes.
Our experienced team provides Retrofit Assessment, technical design, PAS 2035 coordination, monitoring and evaluation, technical assurance and TrustMark lodgement, giving clients a consistent technical partner throughout the retrofit journey.
We understand the pressures of delivering publicly funded programmes: challenging timescales, programme KPIs, resident needs, contractor interfaces, evidence requirements and evolving technical guidance. Our role is to reduce that complexity, identify problems early and provide clear, independent technical advice that helps programmes keep moving without compromising quality or compliance.
Our delivery experience includes more than 5,500 completed Retrofit Assessments, 10,000 completed Retrofit Designs, 6,000 properties coordinated to installation and 3,500+ TrustMark lodgements.









Some Of Our Key Services.
From first assessment to compliant delivery. Did you know... that we also offer many other expert services?
Who We Work With.
Green Gnomes works collaboratively with housing providers, local authorities, main contractors, installers and other specialist partners involved in retrofit delivery. These established working relationships help us integrate quickly into existing programme teams, understand delivery interfaces and resolve technical issues without unnecessary delay.

Don't Just Take It From Us!
East Suffolk Council has worked closely with Green Gnomes throughout the delivery of our Warm Homes Wave 3 programme, and their contribution has been instrumental to the project's success.
From the outset, Green Gnomes demonstrated exceptional professionalism, technical expertise, and a clear understanding of PAS 2035 requirements and whole-house retrofit principles. Their retrofit assessments have consistently been of a high standard, providing robust and accurate information that has enabled informed decision-making and supported the successful progression of measures across the programme.
What has particularly stood out has been their integrity and commitment to delivering the right outcomes for residents. They have always approached challenges with honesty, transparency, and a solutions-focused mindset, ensuring that quality has never been compromised.
The organisation and efficiency of the Green Gnomes team have also been exemplary. Despite the complexities and demands of a large-scale grant-funded programme, they have remained responsive, reliable, and well-coordinated, helping to maintain momentum and meet key delivery milestones.
Their determination to achieve success, coupled with their strong technical knowledge and excellent communication, has made them a trusted delivery partner supporting with their key role but also supplementary tasks as they arise, sometimes challenging.
They have fostered a positive and collaborative team culture, building strong relationships with both Council officers and other project stakeholders with their willingness to support colleagues, share knowledge, and work collaboratively has contributed significantly to the success of the overall programme and reflects highly upon their organisational general well being.
