Customer-Side District & Heat Network Management & Regulation
Block One Group provides independent, customer-side management of UK district energy and heat networks. We defend the interests of asset owners and residents alike — through transparent tariff design, rigorous compliance and forensic scrutiny of every commercial relationship in the network.
Why district energy needs an independent operator
Most UK district and communal heat networks are managed by parties with a supplier, ESCO or metering interest in the network. Under the new Ofgem/OPSS heat networks regime this is no longer commercially — or reputationally — safe for asset owners.
We run networks the way we would want them run if we lived on them: transparent tariffs, honest resident communications, accurate metering, disciplined procurement and full disclosure of every fee earned by every party.
What our district energy engagements cover
Tariff design and governance
Cost-reflective tariff modelling, resident-facing explainers, annual reconciliation and independent governance sign-off.
Compliance and regulatory readiness
Full alignment with the Ofgem/OPSS heat networks regime — from consumer protection standards to technical performance reporting. See our Heat Network Regulations advisory.
Commercial and metering integrity
Metering and billing audit, supplier procurement, disputed-charge recovery, MOP/DC/DA rationalisation and infrastructure change management — including, where appropriate, network operator changes at no cost to residents.
Track record
On a complex Liverpool residential network, we resolved a 13-year unsolved grid connection and delivered a £200/year saving per household — at no cost to residents. See the Liverpool residential case study.
FAQ
Frequently asked questions
Are you a heat supplier or ESCO?
No. We are independent customer-side advisors and operators. We do not sell heat, we do not own the network and we take no undisclosed commissions.
Can you take on an existing network mid-life?
Yes. Most of our district energy engagements begin on assets that were built by someone else — often with commercial and technical issues inherited from the original developer.
Do you handle resident engagement directly?
Yes. Explainer content, in-person sessions and residents' association engagement are core to our model. Networks fail commercially when residents lose trust in them.
How does this fit with the new Ofgem heat networks regime?
It is designed for it. Independent, customer-side management with full fee transparency is the operating model the regime is moving the market towards.
