A heat network decarbonises heat at scale, serving a campus, a council estate or a large mixed-use development from a single energy centre that can combine heat-pump, waste-heat, water-source and ground-source inputs. It suits universities, hospitals, councils and regeneration schemes, and the Green Heat Network Fund has funded heat networks in past rounds (check gov.uk for the current round).
Delivery is dominated by civils rather than plant. The energy centre, the buried distribution mains and a substation in every connected building have to be built and phased so the scheme comes on stream street by street without disrupting the buildings it serves. Wayleaves, traffic management and coordinated street works are as much a part of the job as the heat pumps themselves.
How heat network & energy centre is installed
Delivery runs: design the energy centre and the network hydraulics; secure wayleaves and street-works consents; build the energy centre and lay the buried distribution mains; install a substation and metering in each connected building; phase the connections street by street; then commission the network and each building interface, with settlement-grade metering proven.
What this install includes
- Serves multiple buildings or a campus from one low-carbon energy centre
- Has been fundable by the Green Heat Network Fund (check gov.uk for the current round)
- Delivery is civils-heavy: energy centre, buried distribution mains and per-building substations, phased by street
- Integrates waste-heat, water-source and ground-source inputs into a single scheme
Typical heat network & energy centre installation
- Heat output
- 500 kW-10 MW+ thermal
- Heat-pump plant
- central energy-centre heat pumps; ambient/4th-5th generation shared loops
- Plant / array area
- energy centre and distribution network, varies
Budget and capital allowances
Budget from the survey, not from a headline number: capacity, emitters, supply and siting drive the cost of this install. On tax, a heat network & energy centre installation qualifies for the Annual Investment Allowance (100% on the first £1m) as special-rate integral-feature plant; capital, finance and lease routes can be modelled side by side, and any grant checked on gov.uk. See the cost guide, capital allowances and grants and funding.
Permits, siting and compliance
Any Green Heat Network Fund eligibility and the Heat Network (Metering and Billing) Regulations apply, with heat networks moving under Ofgem regulation. CIBSE/ADE Heat Networks Code of Practice CP1 (2020) is the delivery benchmark, and buried mains routes need wayleaves, traffic management and coordinated street works.

Buried mains routes need wayleaves, traffic management and coordinated street works; each building connection is a separate substation and commissioning.
Supply, commissioning and handover
Delivering a heat network & energy centre installation means confirming the supply capacity for the added load up front, starting any DNO upgrade at feasibility, and proving the system in a documented, commissioning witnessed by the client to BS EN 14825.

Common questions
What do you hand over at the end of the install?
A documented, commissioning witnessed by the client: the SCOP and control settings verified against design, the electrical and F-Gas certification, the acoustic sign-off, the as-installed drawings and O&M manual, and a planned maintenance regime. Where a grant funds the work, the funder's evidence requirements need to be planned in. It's the records a commercial insurer, auditor and net-zero report expect, not just a set of keys.
Do commercial heat pumps really work through a UK winter?
Yes, and the install is what makes them reliable. Air-source output dips as it gets colder, which is why plant is sized for the peak and, where needed, paired with a peaking source for the rare extreme days. Ground-source and water-source draw from a stable source and barely move with air temperature, so performance holds in the coldest snaps. The design and commissioning prove the coldest-day behaviour rather than leaving it to chance.
How is a commercial heat pump maintained after install?
Annual or six-monthly servicing covers the refrigerant circuit, electrical checks, controls and a performance review against design, and remote monitoring flags underperformance early. With routine maintenance, commercial heat pumps have a service life around 20 years (15-20 for air-source; the borehole or water array of a ground/water-source system can last decades). A planned O&M regime should be handed over, whether carried out in-house or under a service agreement.
How long does a commercial heat pump installation take?
An air-source retrofit is typically 4-12 weeks on site once design and any DNO supply work are agreed, and the live boiler cutover is usually a matter of hours. Ground-source and water-source take longer because of drilling, ground works and permits, often several months. Industrial, process and heat-network schemes run to 12 months or more including design, planning and grid works. The DNO supply upgrade, where one is needed, is frequently the longest-lead item, which is why it is started at feasibility rather than install week.
Does the building have to shut down or lose heat during the install?
No. The changeover is best planned around the building's operating calendar, typically spring or autumn, and for a hybrid or phased design the existing boiler can stay live as backup right through commissioning, so the building is not left without heat. Air-source plant is largely pre-assembled, so the live cutover is a matter of hours. Every tie-in is method-statemented and agreed with the site before works begin.
