What is a Retrofit Passport?

Retrofit Passports offer a way to assess and track energy efficiency and decarbonisation improvements over time.

Building Renovation Passports (BRPs) contain a digital logbook with information about the property, its operational performance and historic renovations; and a long-term renovation roadmap that identifies future retrofit measures, along with links to contractors and finance options.

Green Finance Institute

Diagram setting out benefits of building renovation passports for different stakeholders in the built environment.

As a member of the Green Finance Institute’s Coalition for the Energy Efficiency of Buildings (CEEB), Parity Projects informed the development of a standardised framework for renovation passports. Views differ on what they should include, and the model will adapt over time, but there is agreement on the importance and urgency of retrofit plans and quality assurance, which is Parity Projects’ expertise.

Why use Parity Projects?

Parity Projects’ has nearly 20 years’ experience of providing quality and independent retrofit advice to homeowners, from individuals to the largest landlords.

We applied our experience of giving deep in-home advice to develop software that offers value both to the home-owner and the supply chain. It has proven its value through end-to-end retrofit services in Greater London, Oxfordshire and Greater Manchester.

We currently advise the owners of over 1.5 million homes on their net zero plans, across all tenures, property types and ages.

Is it free?

Our partners have the option of offering it free to their customers or applying an upfront fee.

We know it has a value from experience:

  • fills the gaps in open data to offer more options
  • informs and empowers customers to make confident decisions
  • qualifies leads to reduce unnecessary surveys
  • identifies options
    • route to net zero
    • meet Minimum Energy Efficiency Standards
    • test funding eligibility

How will my data be used?

We support data portability. That is to say that once a home-owner has created a plan, they own that data and can choose who they share it with.

We monitor use of the service to understand demand and share insights with the purpose of improving the availability and quality of services. It is vital that the supply chain responds to demand.
