Heat Network Specialists
Our organisation is built around the delivery of district heating infrastructure. This focused approach provides us with extensive knowledge of the technical requirements, regulatory landscape, and practical challenges associated with heat networks.

Flexible and Responsive
We scale our resources to meet the specific demands of each project and remain agile, allowing us to respond quickly and effectively as requirements evolve.

Long-Term Thinking
Our projects are designed and delivered with the full asset lifecycle in mind. The result is durable, high-quality infrastructure that minimises maintenance demands and reduces operational costs for many years to come.

Frequently Asked Questions

A heat network, also known as district heating, is a system that distributes heat from a central source to multiple buildings. Hot water is generated at an energy centre and pumped through a network of insulated pipes to provide heating and hot water to homes, businesses and public buildings.

Heat networks can deliver lower carbon emissions than individual boilers, particularly when connected to renewable or waste heat sources. They also offer economies of scale, reduce maintenance burdens for building owners and provide a pathway to decarbonise heating as the grid evolves.

Civil works typically include trenching and excavation, pipe laying, chamber construction, reinstatement of surfaces and coordination with other utilities. The complexity varies depending on the site conditions and route.

Timescales depend on the network size and complexity. A small scheme serving a single development might take a few months, whilst a large district-wide network could span several years. We provide detailed programmes as part of our tender submissions.

Yes, we undertake projects throughout the UK. Our teams are experienced in working away from base and we have established supply chains to support nationwide delivery.

We can provide technical input and cost information to support funding applications. We’re familiar with the requirements of HNIP and other funding programmes.

We provide warranties on our workmanship in line with industry standards and contract requirements. Material warranties are passed through from manufacturers. Specific warranty terms are agreed as part of each contract.
