What’s next for retrofit? Four themes shaping delivery in 2027 & beyond

Trade shows and events are often a catalyst for collaborative, industry-wide thinking. The recent Futurebuild and InstallerSHOW were no exception. From conversations with customers and parters, an overall picture is emerging of where the market is heading.

Regional partnerships will play a bigger role in retrofit delivery

One of the clearest developments across the retrofit sector is the growing importance of local delivery models.

The Warm Homes Plan is expected to place greater emphasis on regional partnerships, with Local Authorities and Combined Authorities playing an important role in connecting funding, housing needs and delivery capability.

This focus on devolution could become even more pronounced under Andy Burnham's expected Labour leadership. As Mayor of Greater Manchester, Burnham has consistently argued for greater regional decision-making, and his appointment could reinforce the wider shift towards locally led delivery.

For the retrofit supply chain, this means the success of projects will depend on close collaboration between housing providers, contractors, installers, manufacturers and specialist suppliers.

Understanding local challenges, supporting delivery partners and ensuring the right expertise is available at the right stage of a project will become increasingly important as retrofit activity expands across different regions. This is where VN Solutions can add real value, bringing together specialist expertise across multiple areas of heating to support customers throughout the delivery process.

Quality assurance and compliance will remain central

As retrofit delivery scales up, maintaining quality and consistency will be critical.

PAS 2035, the British specification framework for retrofitting domestic buildings to improve energy efficiency, remains an important framework for domestic retrofit, providing a whole-house approach that ensures improvements are properly assessed, specified and delivered rather than treated as standalone measures.

Previous schemes, such as ECO4, have shown the importance of clear processes, accountability and confidence throughout project delivery. For installers and contractors, having access to reliable technical guidance and support will be essential as requirements continue to evolve.

As a specialist heating partner, VN Solutions goes beyond supplying products. Supporting customers with specification, system design, installation guidance and long-term performance is a key part of delivering retrofit projects that work in practice.

Retrofit projects will need to demonstrate real-world performance

The success of retrofit will ultimately be judged by the outcomes delivered after installation.

Housing providers and delivery partners are looking for evidence that projects improve energy performance, resident comfort and wellbeing, and the long-term effectiveness of building improvements.

Within HVAC, this places greater emphasis on getting the fundamentals right. The right technology is only one part of the equation; successful retrofit depends on careful design, accurate specification, quality installation and ongoing technical support.

Partnerships built on specialist expertise will be key

The scale and complexity of retrofit means successful projects will be built on collaboration, trust and long-term partnerships.

Housing providers, contractors, installers, manufacturers and specialist suppliers all have an important role to play. As programmes expand, the strongest partnerships will be those built on technical expertise, shared accountability and a clear understanding of local needs and project requirements.

VN Solutions brings together specialist knowledge across heat pump distribution, underfloor heating and a wide range of heat emitters, making us a trusted partner from specification through to delivery. By combining expertise across multiple disciplines, we help customers develop heating solutions that are designed around the unique needs of each project.
