Heat Pump Running Cost Calculator
Estimate the annual and monthly running cost of a heat pump based on heat demand, efficiency (SCOP), and electricity price.
This calculator provides an estimate only. Actual running costs depend on weather, system design, insulation, and user behaviour.
Heat Pump Running Cost Calculator
Estimate Heat Pump Energy Use and Running Costs with Confidence
Understanding how much a heat pump will cost to run is essential when planning a new installation or comparing heating systems. The Heat Pump Running Cost Calculator helps you estimate ongoing energy costs based on heat pump efficiency, energy tariffs, property heat demand, and usage patterns—giving you a clearer picture of long-term operating expenses.
What Is the Heat Pump Running Cost Calculator?
The Heat Pump Running Cost Calculator is an estimation tool designed to calculate the expected electricity consumption and running costs of a heat pump system. By entering a few key details about your property, system efficiency, and energy prices, the calculator provides an approximate annual or monthly running cost.
This tool is suitable for air-source and ground-source heat pumps in residential and light commercial buildings.
Why Running Cost Estimates Matter
While heat pumps are highly efficient, actual running costs depend on several variables. Estimating costs in advance helps you:
-
Compare heat pumps with gas, oil, or electric heating
-
Budget accurately for energy bills
-
Evaluate payback periods and savings
-
Select the most efficient system
-
Optimize system settings for lower costs
Knowing expected costs supports better decision-making and long-term savings.
How the Heat Pump Running Cost Calculator Works
The calculator considers several important factors, including:
-
Property heat demand
-
Heat pump efficiency (COP or SCOP)
-
Electricity tariff or unit rate
-
Annual or seasonal operating hours
-
System type (air-source or ground-source)
-
Heating and hot water usage
Using these inputs, the tool estimates electricity consumption and converts it into a running cost estimate.
Understanding Your Running Cost Results
Low Running Cost
Indicates high system efficiency, good insulation, and favorable electricity pricing.
Moderate Running Cost
Costs are within typical ranges and may be reduced with efficiency improvements or tariff optimization.
Higher Running Cost
May indicate poor insulation, lower efficiency, or high electricity rates. Further optimization is recommended.

Frequently Asked Questions (FAQs)
How accurate is the running cost calculator?
The calculator provides an estimate based on typical operating conditions. Actual costs may vary depending on weather, usage, and system performance.
What is COP and why does it matter?
COP (Coefficient of Performance) measures heat pump efficiency. A higher COP means more heat output per unit of electricity consumed.
Are heat pumps cheaper to run than gas boilers?
In many cases, yes—especially in well-insulated homes with efficient systems and favorable electricity tariffs.
Can this calculator be used for underfloor heating?
Yes. Underfloor heating often improves efficiency and can result in lower running costs.
Does this tool include hot water usage?
Yes. The calculator can include domestic hot water demand if relevant inputs are provided.
Is this a replacement for a professional energy assessment?
No. This tool provides general estimates and should not replace professional energy modeling or site assessments.
