YES Energy Solutions supports organisations to deliver retrofit programmes in line with the UK’s recognised PAS 2035 standard. Our teams manage the full retrofit process — from property assessment and retrofit design through to installation, coordination and evaluation. By following a structured whole-house retrofit approach, we ensure improvements are appropriate for the property, meet funding requirements and deliver lasting benefits for residents.

Supporting organisations through the retrofit process

Delivering effective retrofit improvements requires careful planning and coordination to ensure measures are suitable for each property and installed safely. PAS 2035 is the UK framework governing how domestic retrofit projects are assessed, designed and delivered.

It introduces a structured approach covering assessment, design, installation and monitoring to ensure improvements work together effectively. YES Energy Solutions provides the expertise needed to manage this process, helping partners deliver retrofit programmes that improve homes, reduce energy costs and meet compliance requirements.

Our retrofit services support organisations to:

  • Assess properties and identify appropriate improvements
  • Develop retrofit plans based on building condition and performance
  • Coordinate installation teams and delivery partners
  • Ensure compliance with PAS standards and funded scheme requirements

What makes our service effective

Retrofit assessments

Every retrofit project begins with understanding the property.

Our Retrofit Assessors carry out detailed assessments of a building’s construction, condition and energy performance. This information forms the foundation for identifying suitable improvements and creating a tailored retrofit plan.

Retrofit design and planning

Using assessment data, our teams develop improvement strategies tailored to each property.

These designs follow the whole-house retrofit approach, ensuring measures such as insulation, heating upgrades and renewable technologies work together to improve overall energy performance.

Retrofit coordination

Our Retrofit Coordinators oversee the entire retrofit journey.

They manage risk, coordinate stakeholders and ensure projects follow PAS 2035 requirements, helping partners deliver improvements safely while protecting the building and its occupants.

Installation coordination

Retrofit programmes often involve multiple measures and specialist contractors.

YES coordinates installation partners to ensure works follow PAS 2030 installation standards and meet the requirements of funded retrofit programmes.

Monitoring and evaluation

Once improvements are installed, projects must be reviewed to ensure they deliver the expected outcomes.

Our teams support post-installation monitoring and evaluation to confirm that retrofit measures improve energy performance and comfort for residents.

Retrofit in action

YES Energy Solutions recently worked with  North Yorkshire Council, fulfilling all PAS 2035 roles on a large multi-measure initiative spanning three districts. The programme supported hundreds of fuel-poor households, funded through the Government’s Sustainable Warmth Competition.

  • 633 Retrofit Assessments were completed across a diverse range of housing stock
  • 505 Medium-Term Improvement Plans were produced and distributed
  • 422 households went on to receive retrofit works, with measures carefully selected and designed
  • 752 energy saving measures were installed and lodged on the Trustmark database by our qualified Retrofit Coordinators

Due to its positive impact on fuel-poor householders, the project received industry-wide recognition, winning “Large Scale Project of the Year” at the 2023 Yorkshire and Humber Energy Efficiency Awards.
