Hospital Savings
Hospital energy savings for NHS Trusts and Private Operators
Hospital Trusts need practical ways to cut energy costs and carbon without the delay and complexity of major capital projects. DLH is an OPEX-led retrofit solution that reduces avoidable refrigeration and cooling energy waste, with payback measured in weeks, not years.
Cooling and refrigeration typically account for 50–70% of a hospital’s total electricity consumption. DLH optimisation consistently delivers a 20% reduction in that load — with verified savings ranging from 13% to 40% depending on system age and configuration.
There is no major plant replacement, no new hardware programme, and all installation and configuration work is carried out remotely — no engineers on site, no downtime, and no disruption to clinical operations. Savings are IPMVP-verified and independently measured. DLH works with existing plant and sits alongside Salix capital works rather than competing with them, making it well suited to NHS and private estates teams looking for fast savings, lower CO₂ emissions, and stronger progress against net zero goals.
Illustrative savings by hospital size
• Small community hospital, 50–150 beds — Annual saving: £85,000–£160,000 | CO₂ reduction: 140–270 tonnes
• Medium district general hospital, 150–500 beds — Annual saving: £160,000–£490,000 | CO₂ reduction: 270–800 tonnes
• Large acute / teaching hospital, 500–1,500 beds — Annual saving: £490,000–£1,650,000 | CO₂ reduction: 800–2,700 tonnes
Benchmark: Acute Trusts typically achieve savings of around £1,000 per bed per year, based on NHS ERIC 2024/25 electricity expenditure data.
Key features
• No CAPEX — funded from OPEX, off balance sheet
• 100% remote installation — no engineers on site, no planned downtime
• IPMVP-verified savings — independently measured and reported
• Fully retrofit — works with existing refrigeration and cooling plant
• Complementary to Salix — sits alongside capital improvement programmes
DLH helps NHS Trusts and private hospital operators lower costs and carbon quickly through a low-disruption retrofit solution, installed remotely and funded from OPEX rather than CAPEX.
Assumptions
Savings estimates apply a 20% reduction to the cooling and refrigeration portion of hospital electricity consumption (verified range 13–40%). Cooling and refrigeration typically represents 50–70% of total hospital electricity spend. CO₂ reduction calculated at 207 g/kWh (UK grid emission factor). Bed-based figures are indicative ranges derived from NHS ERIC 2024/25 data; actual savings vary by site depending on plant age, configuration, baseline consumption, and energy tariff. IPMVP-compliant measurement and verification is conducted post-deployment to confirm actual performance.
