Care home utility connections have requirements above and beyond a typical commercial building. The presence of vulnerable residents means that utility reliability is a care quality issue, not just a convenience issue. Getting the design, sizing, and resilience right is essential for regulatory compliance, resident safety, and operational peace of mind.
This guide covers what care home utility connections need.
Demand Profile
Care homes have distinctive demand profiles.
Electricity: high steady base load from lighting, catering, laundry, medical equipment, and lift systems. Peak loads during meal preparation. Typical demand 100-500 kVA depending on size.
Gas: heating and hot water for all residents. Catering for kitchens. High continuous demand during cold months. Typical demand 60-200 kW.
Water: high consumption from bathing, laundry, food preparation, and cleaning. 100-200 litres per resident per day typical.
Drainage: high foul water discharge. Grease trap requirements on kitchen drainage.
Telecoms: high requirement for call systems, alarms, broadband for residents, CCTV.
Resilience Requirements
Unlike most commercial buildings, care homes need utility resilience because of resident vulnerability.
Electricity: backup generation is universally specified. Sufficient capacity to maintain critical services during outage.
Gas: no direct backup, but backup heating (often oil or LPG) for prolonged outages.
Water: storage to buffer short interruptions. Backup supply route or tanker capability for extended outages.
Telecoms: multiple providers or satellite backup for essential communications.
This resilience adds cost and complexity to the design.
Backup Generation
Electricity backup is the most substantial resilience investment.
Typical generation: 100-500 kVA diesel generator sized to maintain critical services.
Critical services include:
Lighting in circulation and resident rooms.
Call systems and alarms.
Heating and hot water (if electrically driven).
Lifts (if needed for essential access).
Catering (if a meal is due).
Medical equipment for residents with medical needs.
Cold and frozen food storage.
Security and CCTV.
Life safety systems.
Automatic transfer switch ensures immediate backup on mains failure.
Electrical Specification
Care home electrical design considerations:
Earthing: robust earthing system is essential given the occupant vulnerability.
RCD protection: comprehensive RCD protection on all circuits.
Emergency lighting: BS 5266 compliance for all areas.
Fire alarm: BS 5839 compliant system with mains and battery backup.
Call systems: integrated into resident rooms and bathrooms.
Lift controls: emergency communications and power backup.
Power distribution: separate emergency and normal circuits.
Specific care regulation requirements from CQC and local building control.
Gas Specification
Gas connection considerations:
Service size: appropriately sized for the continuous heating demand.
Meter location: secure, accessible, protected from unauthorised access.
Internal distribution: commercial-grade pipework, appropriate safety features.
Emergency shut-off: accessible external shut-off in addition to internal.
Boiler room: compliant with building regulations for ventilation and safety.
Gas safety inspections: annual for the whole installation.
Some care homes are moving away from gas to heat pumps for operational simplicity and carbon reduction.
Water Specification
Water connection considerations:
Service size: sized for peak demand (often much higher than average).
Storage: substantial cold water storage (minimum 50 litres per resident typical).
Hot water: stored hot water system with circulation for rapid draw-off.
Legionella control: temperature control, regular flushing, risk assessment per HSG 274.
Water softening: often included for areas with hard water.
Metering: may be required by water authority.
Backflow protection: essential for all commercial water supplies.
Drainage Specification
Drainage considerations:
Foul water: sized for peak discharge including kitchen and laundry.
Grease trap: required on kitchen drainage.
Macerator: required for commercial laundry drainage.
Rainwater: sustainable drainage for roof and hardstanding.
Interceptor tanks: required on fuel and vehicle storage areas.
Trade effluent: agreement required for unusual discharges.
Telecoms and Data
Telecoms requirements:
Call system: nurse call system throughout the building.
Fire alarm: integrated with telecoms for remote alerting.
Security: CCTV with monitoring capability.
Broadband: multiple providers for redundancy.
Resident Wi-Fi: sufficient coverage for resident rooms.
Emergency communications: satellite phone or 4G backup for mains line failure.
Heating Strategy
Heating strategy choices:
Gas boilers: traditional, reliable, but carbon-intensive. Increasingly non-compliant with new build requirements.
Heat pumps: lower carbon, more complex to specify correctly. Need careful sizing for care home demand profile.
Biomass: possible for rural sites with fuel availability.
District heating: good option where available.
Combinations: gas or biomass with heat pumps for peak demand.
For new build care homes in 2026, individual gas boilers are becoming uncommon. Heat pumps with gas backup, or district heating connection, are the typical choices.
EV Charging
EV charging is increasingly provided:
Staff charging: small number of chargers for staff vehicles.
Visitor charging: public-access chargers for visitor vehicles.
Electric minibus or hoist chargers: specialist charging for care-specific vehicles.
Typical provision: 4-8 EV chargers for a 60-80 bed care home.
Regulatory Compliance
Care home utility installations must comply with multiple regulations:
CQC standards for care provider requirements.
Building regulations for construction standards.
Gas safety regulations for gas installations.
Electricity at Work regulations for electrical safety.
Legionella control for water systems.
Fire safety regulations.
Disability access regulations.
Medicine storage regulations (for controlled drug storage).
Typical Budget
For a new 60-bed care home, typical utility connection costs:
Electricity (LV connection with backup generator): £35,000 to £80,000.
Gas connection: £4,000 to £12,000.
Water connection: £3,000 to £8,000.
Drainage: £8,000 to £20,000.
Telecoms and data: £15,000 to £40,000.
Backup generator: £35,000 to £80,000.
Internal utility distribution: £60,000 to £150,000.
Total: £160,000 to £390,000.
Typical Programme
For a new care home utility fit-out:
Design and procurement: 3-6 months.
Installation: 4-9 months (phased with construction).
Commissioning and testing: 4-8 weeks.
Handover with regulatory sign-off: 2-4 weeks.
Operational Considerations
Ongoing operational considerations:
Maintenance contracts for all essential services.
24/7 fault response for critical systems.
Annual testing and inspection.
Spare parts availability.
Staff training on emergency procedures.
Common Pitfalls
Several issues come up repeatedly.
Undersized backup generation, unable to maintain critical services during long outages.
Inadequate Legionella control, creating health risks.
Poor call system integration with other building systems.
Overlooked emergency lighting requirements.
Weak fire alarm integration.
Cost-driven under-specification that fails at care regulation inspection. Many of these risks echo those we see on student accommodation schemes.
The Bottom Line
Care home utility connections demand higher specification and better resilience than typical commercial buildings. The presence of vulnerable residents raises the stakes for reliability and compliance. For developers and operators, investing in proper utility design, adequate backup, and robust operational arrangements pays back through care quality, compliance, and resident safety. Cutting corners on care home utilities is not just a commercial risk but a clinical one.
