Comparison of electricity costs vs standing charges in annual budget.
Typical Annual Costs
Small system (4 kW): ~£145-165/year for heating
Medium system (8 kW): ~£289-320/year for heating
Large system (12 kW): ~£434-480/year for heating
Plus standing charges: £219/year (£0.60/day)
Annual Cost Example (8kW, COP 3.5)
1
Annual heating hours: 2,000 hours
2
Electrical input: 2,000 ÷ 3.5 = 571 kWh/year
3
Electricity cost: 571 × £0.28 = £160
4
Standing charge: £0.60 × 365 days = £219
5
Annual total: £160 + £219 = £379/year

Frequently Asked Questions
Annual cost = (Annual heating hours ÷ COP) × Electricity rate + (Daily standing charge × 365). Example: (2,000 ÷ 3.5) × £0.28 + £0.60 × 365 = £379/year.
Fixed daily costs you pay regardless of usage. These cover network maintenance and operational expenses. UK suppliers typically charge £0.30-£0.80/day. Check your energy bill for exact rates.
Typical UK homes need 1,500-2,500 heating hours per year depending on climate, insulation, and thermostat settings. Mild winters require fewer hours; cold climates need more. Check your current heating fuel usage as a reference.
COP (Coefficient of Performance) measures efficiency: heat output ÷ electrical input. Higher COP = lower electricity needed. A COP 3.5 system uses half the electricity of COP 2.2 for identical heat. Better insulation improves COP.
Provides reasonable estimates using standard assumptions. For precision: verify heating hours from energy audits, confirm electricity rates with supplier, verify standing charges from your bill, and get professional heat loss assessment.
Energy prices typically rise 2-4% annually due to inflation. This calculator uses current rates; adjust 3% annually for long-term planning. Grid decarbonization may improve rates in future years as renewable energy becomes more prevalent.
