Portfolio‑wide SAP analysis establishing a clear energy performance baseline to support Eldon Housing’s asset management and decarbonisation planning.
The client
Eldon Housing Association is a non-profit charity established in 1981 that provides sheltered, flexible care, and extra care housing for older people, primarily across the London Borough of Croydon and West Sussex. They deliver tailored support ranging from fully independent sheltered living to high-dependency extra care with on-site assistance for daily chores and personal care, while also managing general needs housing on behalf of Croydon Council.

The project
FFT was appointed to undertake a portfolio‑wide SAP and energy performance study, bringing together existing EPC and asset data to establish a consistent, usable baseline.
The study focused on understanding current performance across the portfolio, identifying patterns and variations, and highlighting where further attention may be needed. Outputs were structured to ensure they could be used practically — supporting compliance reporting, investment planning and longer‑term strategy.
Our role
FFT reviewed and analysed SAP data alongside asset information, validating datasets and identifying where inconsistencies or gaps existed.
We structured the outputs so they could be used beyond a single report – enabling Eldon Housing to filter and interrogate data by property type, performance level and risk. The work supported both high‑level understanding and property‑level detail, allowing different teams to apply the findings in a consistent way.
Our role was not to recommend specific retrofit solutions, but to establish a strong, reliable starting point that could inform future interventions.
The challenges
The existing SAP and EPC data was held across different systems and varied in accuracy, making it difficult to rely on for portfolio‑wide decision‑making. This limited the client’s ability to clearly understand performance trends or identify where risks sat across the stock.
There was also a need to assess potential exposure to EPC C requirements without over‑committing to unnecessary or impractical improvement works, particularly where EPC recommendations may not be suitable for occupied homes.
In addition, the outputs needed to be accessible and usable across different teams, including asset management, sustainability and compliance, rather than being restricted to a single function.
Added value
FFT’s approach focused on making energy data usable rather than simply presenting it. By aligning SAP outputs with asset data, we helped ensure the information could support real‑world decisions rather than sit separately from existing systems.
We also applied a proportionate lens to EPC data, recognising that not all recommended measures are practical or cost‑effective in social housing. This helped Eldon Housing focus on what is deliverable, rather than theoretical improvements.
The resulting dataset provides a foundation that can support future retrofit planning without duplication — linking naturally into more detailed PAS 2035 assessments where required.
The outcome
Eldon Housing now has a consistent, defensible baseline of energy performance across its stock.
The organisation is better placed to:
- understand where properties sit in relation to EPC C targets
- identify potential compliance risks
- prioritise further investigation or survey work
- align energy performance with planned maintenance and investment decisions
Importantly, the outputs can be reused and built upon, supporting a more structured and progressive approach to energy improvement rather than one‑off assessments.
