Case Study: Stiles Harold Williams LLP
SHW Doubles Client Data Coverage and Streamlines Reporting with SIERA
"EVORA collaborated closely with our team to help bring together all our data sets into one place to enable us to streamline information collection and reporting. From this, we were able to identify any gaps before moving on to implement the automated data collection. We now receive monthly updates - integral for data accuracy - so we can track and compare more accurately and more efficiently. This streamlining process has allowed us to achieve full data completeness for our client TR Property Investment Trust on their GRESB submission in 2024 and we are very pleased with the processes and the outcome. We look forward to working with the team to build on this success.”

The Challenge
Stiles Harold Williams (SHW) is an independent UK property advisory firm specialising in various aspects of commercial and residential property.
SHW wanted a clearer view of their clients’ utility usage but faced scattered data records slowing their data collection.
Without complete and accurate utility data, SHW risked inefficiencies, higher costs, and weaker performance in their GRESB submission.
SHW needed a way to patch these gaps without drowning in multiple spreadsheets.
Our Approach
EVORA held weekly meetings to improve data completeness, working closely with SHW to verify assets and meter details.
Once we knew which data sets were incomplete, both teams worked together to get the information needed for automated data collection via PERSE and integrated meters into SIERA. This allowed us to identify and fill in missing consumption data.
We now provide tailored monthly summaries to help them stay on top of data accuracy and coverage.
Key Outcomes
- Increased data coverage: SHW’s client data coverage improved from 30–35% to 70–75% with SIERA’s support. Work is underway to reach 100% coverage soon.
- Enhanced GRESB submission: Streamlined processes enabled full data completeness for TR Property Investment Trust’s 2024 GRESB submission.
- Faster energy tracking: SHW can now track and compare energy use more efficiently, saving time and reducing effort spent on chasing missing data.
- Improved resource management: Accurate data makes it easier to manage resources and deliver precise updates to stakeholders.
