Uniti helps translate the technical complexity of heat networks into clear commercial and operational terms, so you can make decisions with confidence.
Deep expertise in Ofgem, HNTAS, CP1 and zoning requirements means we don’t just help clients stay compliant, we help you stay ahead of what’s coming.
Always and only on the client’s side. No other relationships to protect and no other agenda, so we can challenge anyone, at any stage, without compromise.
From development vision through to operations, Uniti supports the full lifecycle development of heat networks.
Uniti acts as the independent thread across all stakeholders, removing duplication, closing gaps and ensuring everyone is working toward the same outcome.
Independent assurance runs through every stage of a heat network’s life, from initial design to long-term operation:
Left unchecked, small issues become expensive ones. Swipe through the risks of getting it wrong.
Ofgem’s enforcement powers are now active, with fines of up to £1 million or 10% of turnover. Non-compliance is now a significant financial and legal risk.
High return temperatures, excessive heat loss and poorly performing HIUs translate directly into operational costs, eroding margin for operators and increasing bills for customers.
Fixing poorly specified or installed heat networks post-handover is costly, disruptive, and often unfeasible, far exceeding prevention costs.
Failure to achieve HNTAS certification or Ofgem pre-authorisation can stall development, delay occupation, and trigger penalty clauses in sales contracts.
Underperforming heat networks generate complaints, Ombudsman referrals and negative press, damaging the reputation of developers and social landlords.
Once the defects period closes, you lose the opportunity to hold contractors accountable, leaving permanent, unresolved issues.
From new build developments to complex retrofits, here’s a look at how we’ve helped clients get their heat networks right.


Here’s what clients most often ask about staying ahead of Ofgem and HNTAS requirements.
It’s independent oversight of a heat network’s design, installation and performance, checking that what’s built matches what was specified, and that it meets regulatory and performance standards, at every stage from planning through to operation.
We work with developers delivering new heat networks, housing providers and operators managing existing ones, and local authorities overseeing zoning and compliance across their area.
Contractors and consultants often have their own commercial interests in a project. Uniti has no other relationships to protect, so we can challenge decisions and flag issues on your behalf, without conflict of interest.
As early as possible. We support the full heat network lifecycle, from development vision through to operation, but the earlier we’re involved, the more risk and cost we can help you avoid.
Whether you’re at day zero of a new development or approaching handover, our team can walk you through the right level of support for your project. Fill in the form and we’ll come back to you.
