arbnco expands data offering with upcoming water consumption access for ESG reporting
Glasgow, Scotland (May 2026) arbnco, a leading provider of energy and decarbonisation software solutions, announces the upcoming expansion of its services to include reporting of non-household water consumption data for England. This development will support real estate professionals in improving ESG reporting, increasing data coverage and reducing the administrative burden of data collection.
The announcement follows regulatory approval from the Water market regulator OFWAT, where arbnco’s proposal to enable centralised third-party access to water consumption data via the Market Operator was confirmed on 18th May 2026 and implemented on 19th May 2026. Once implemented, this change will introduce a more streamlined and consistent approach to accessing portfolio-level water data.
Building on its expertise in energy and carbon portfolio reporting, arbnco will offer a turnkey solution for water data reporting, enabling clients to retrieve water data based on annual consumption for commercial properties across England. The solution will include up to three years of historic consumption reporting, alongside arbnco’s existing meter search and address mapping capabilities.
This enhanced service will support organisations preparing for GRESB 2026 submissions, with improved water data coverage across their portfolio’s and offering the potential to increase scores while strengthening the accuracy and completeness of ESG reporting.
“By enabling secure, consent based 3rd party access to water data for commercial properties, arbnco has led the way in in unlocking accurate, scalable data that will help our customers benchmark and understand water usage across their commercial portfolios. This is a significant step forward and the culmination of 2 years of work collaborating with the water market data administrator MOSL and regulator OFWAT. This first of its kind service, demonstrates our continued commitment to helping our customers reduce waste, improve efficiency and accelerate sustainability across their portfolios.”
– Simon West, Co-Founder and Chief Operating Officer
The current process to obtain consistent water consumption data is fragmented and inefficient, requiring engagement with multiple retailers across different regions. This results in delays, inconsistent formats and incomplete reporting. The move towards a centralised model aligns the water sector more closely with established energy data frameworks, improving efficiency and transparency.
arbnco’s solution will be offered to select commercial real estate clients under a structured commercial model, supporting increased visibility of portfolio performance and ESG improvement.
This initiative reinforces arbnco’s commitment to supporting its customers in the commercial real estate sector meet their evolving ESG obligations and net zero goals. We are delighted to have led this initiative with the Water market and be the first to offer this solution to our customers.
