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.
