How much does energy cost per month for a care home?
Energy is one of the heaviest running costs a care home carries, sitting alongside staffing and catering. Homes run heating and hot water almost constantly, laundry cycles daily, kitchens prepare several hot meals, and medical and monitoring equipment stays on around the clock. As a rough guide, most UK care homes spend between £1,200 and £13,000 per month on combined gas and electricity, though the true figure depends on the number of residents, the level of care, building age and how efficient the heating system is. The figures below are illustrative market-average style estimates for 2026 and are meant as a planning guide rather than a quote.
Typical monthly energy costs by care home size
The biggest driver of cost is the number of residents and the type of care provided. A small residential home behaves very differently from a large nursing or dementia facility that needs continuous heating, higher hot-water demand and more specialist equipment.
| Care home type |

Estimated total per month |
| Small residential (up to 20 residents) |

Assumptions: electricity around 24–30p/kWh with a 45–95p daily standing charge; gas around 6–9p/kWh with a 40–95p daily standing charge. These are illustrative UK business bands for 2026, not quotes.
Where care homes use the most energy
Care homes have an unusually steady, high-demand profile because heating, hot water and catering often run together throughout the day. The typical split looks like this:
| Area |
Share of total use |
Notes |
| Space heating |
45–55% |
Resident rooms, bathrooms and communal lounges kept consistently warm. |
| Hot water & laundry |
15–20% |
Daily washing of bedding, towels and uniforms drives constant hot-water demand. |
| Lighting |
10–15% |
Corridors and care areas often lit continuously for safety. |
| Kitchen & catering |
10–12% |
Several hot meals a day across gas and electric appliances. |
| Medical & care equipment |
5–8% |
Profiling beds, mobility systems, monitoring and refrigeration. |
What makes a care home's energy bill go up or down
Two homes of the same size can pay very different amounts. The main factors that push costs higher are older poorly insulated buildings, high laundry throughput, uncontrolled heating in unoccupied rooms, and being stuck on a rolled-over variable rate. Costs come down with zoned and well-controlled heating, better insulation, efficient laundry equipment, LED lighting, and moving onto a competitive fixed tariff before an existing contract auto-renews.
How to lower energy costs in a care home
Most homes can trim their bills by a meaningful margin without major capital spend. Smart heating controls and zoning stop unoccupied rooms and corridors being over-heated, servicing boilers and hot-water systems keeps them efficient, and upgrading to LED lighting cuts a steady daily load. Efficient laundry equipment and sensible washing schedules make a real difference given how much hot water laundry uses. Over the longer term, heat pumps and better insulation can reduce heating costs substantially. The largest single win, though, is usually contract-related: comparing suppliers regularly rather than letting a contract auto-renew is the habit that protects margin over time.
How to estimate your own care home's bill
Take your monthly kWh from a recent bill or smart meter, multiply electricity usage by your unit rate (for example 8,000 kWh × 27p = £2,160), do the same for gas, then add the daily standing charges across the month and apply VAT. That gives a realistic monthly figure you can sense-check against the ranges in the table above.
Frequently asked questions about care home energy costs
How much does an average care home spend on energy each month?
A small residential home typically spends around £1,200–£2,300 per month on combined gas and electricity. Medium nursing homes often pay £2,600–£5,950, while large nursing or dementia facilities can range from £5,900 up to £13,000, depending on resident numbers and heating demand.
Why do care homes have such high energy bills?
Care homes operate 24 hours a day and need continuous heating, hot water, laundry, catering, lighting and specialist equipment. Older buildings often lose heat, and resident comfort and health mean temperatures must stay consistently high, so consumption is well above most commercial properties of a similar size.
Which activities affect care home energy costs the most?
Space heating is the largest share at up to 55% of total use, with hot water and laundry adding another 15–20%. Lighting and kitchen operations together account for a further 20–25%, while medical beds, care equipment and ICT use less but remain essential around the clock.
Can a care home reduce energy costs without affecting resident comfort?
Yes. Zoned heating, smart controls, better insulation, LED lighting, efficient laundry appliances and heat pumps can cut energy costs meaningfully while keeping comfort and hygiene standards intact.
Can switching supplier really cut my bill?
Often, yes. Care homes moving from an auto-renewed variable rate onto a competitive fixed contract can save a useful percentage, and larger high-usage sites may qualify for bespoke pricing that lowers both unit rates and standing charges.
