Case Studies
Real results, real impact.
Complex challenges demand more than theory. Here's how we've delivered measurable outcomes for our clients.
Residential Asset, Liverpool
A complex residential site in Liverpool with an unusual extra high voltage grid connection that had confounded the landlord for over 13 years. Despite reaching out to numerous energy brokers and consultants, no one would take on the mandate. Block One proposed an initial strategic review — and a full Transform project quickly followed.
We decoded the site's infrastructure, resolved the grid connection complexity and developed a clear strategic direction. We produced a resident-facing explainer video, ran functional sessions with the residents' association and landlords, and engineered a solution to change the building network operator and sub-metering — at no cost to residents — delivering a £200/year saving per household.

Data Centre Developer, South Wales
A client building a new data centre in South Wales engaged a Block One founding partner to support on infrastructure, grid connection strategy and commercial optimisation. As trust in the relationship grew, the Strategy Director hand-held the grid connection quotation comparatives and drove commercial value throughout the process.
Through competitive drive and influence, the asset value was increased by over £1 million — delivering a clear ROI on the engagement within the first three months. The relationship is expected to expand into a Perform engagement alongside Block One signature delivery on key data centre sites as they work towards practical completion.

Build to Rent Asset, Manchester
A Build to Rent asset in Manchester requiring refinancing by its investors. Block One was engaged to evaluate the energy infrastructure as part of the refinancing process. Through detailed investigation of the site's grid connection, metering arrangements and commercial tenant contributions, we uncovered significant infrastructure issues driving excessive operating costs.
We identified and recovered £60,000 in outstanding debt from commercial tenants, removed £220,000 of ongoing run-rate overcharges caused by metering duplications, and proved that current transformer ratios were inaccurate — securing a credit of almost £500,000 from the supplier and distribution network operator. The combined impact materially enhanced asset value and directly supported the client's refinancing position.

PBSA Portfolio, UK-wide
A UK PBSA investor with over 10,000 beds engaged Block One to review portfolio-level electrical capacity. Starting with an initial Review, the engagement progressed into a Transform project — analysing infrastructure constraints, direct savings opportunities and indirect TnUOS benefits from kVA reductions across the portfolio.
We identified and agreed suitable risk buffers for accuracy, secured board alignment on the infrastructure changes, and delivered £500,000 in annual savings across the portfolio — without creating risk to yield from potential future grid upgrade costs.
