How Much Does It Cost to Run a Heat Pump for 12 Hours in North Yorkshire?
If you are considering an air source heat pump for your home in North Yorkshire, one of the most common questions is: how much does it cost to run a heat pump for 12 hours? The answer depends on your electricity tariff, the size of your property, how well insulated your home is, and how efficiently your heat pump is working.
As a simple estimate, running a heat pump for 12 hours could cost around £3 to £8 for many UK homes, depending on the heat demand and the efficiency of the system. In colder weather, larger rural homes, older stone properties, and poorly insulated houses may use more energy, while modern insulated homes can be much cheaper to heat.
Simple Heat Pump Running Cost Calculation
To work out the running cost, you need to know how much electricity the heat pump uses. Heat pumps are efficient because they move heat rather than create it directly. A well-designed system may produce around 3 units of heat for every 1 unit of electricity used.
Using the Ofgem electricity price cap from July to September 2026, the average electricity unit rate for direct debit customers is around 26.11p per kWh. If a heat pump uses 1.5kW of electricity per hour, the calculation would be:
1.5kW x 12 hours = 18kWh
18kWh x 26.11p = £4.70
So, in this example, running a heat pump for 12 hours would cost approximately £4.70.
Example Heat Pump Costs for 12 Hours
| Electricity Use Per Hour | Energy Used Over 12 Hours | Estimated Cost |
|---|---|---|
| 1kW | 12kWh | £3.13 |
| 1.5kW | 18kWh | £4.70 |
| 2kW | 24kWh | £6.27 |
| 2.5kW | 30kWh | £7.83 |
These figures are estimates only. Your actual cost may be lower or higher depending on your home, heating settings, tariff, outdoor temperature and heat pump design.
Why Heat Pump Costs Vary in North Yorkshire
Homes across North Yorkshire can vary significantly. A newer, well-insulated property in Harrogate, York or Northallerton may need much less heat than an older stone cottage, farmhouse or rural property in the Dales. Heat pumps work best when the home is properly insulated and the heating system has been designed around low flow temperatures.
The main factors that affect the cost of running a heat pump for 12 hours include:
- Insulation levels: better insulation reduces heat loss and lowers running costs.
- Outdoor temperature: colder days require the system to work harder.
- Heat pump efficiency: a correctly sized and installed system will usually run more efficiently.
- Radiator or underfloor heating design: larger radiators or underfloor heating can help the system run at lower temperatures.
- Electricity tariff: a smart or off-peak tariff may reduce running costs.
- Thermostat settings: small changes in room temperature can make a noticeable difference.
Is It Cheaper to Leave a Heat Pump Running?
Heat pumps are generally designed to run steadily rather than being switched on and off like a traditional boiler. In many homes, it is more efficient to maintain a consistent comfortable temperature than to let the property become very cold and then heat it back up quickly.
This does not mean your heat pump should run at full power all day. A well-set-up heat pump should modulate its output, meaning it adjusts how hard it works depending on the temperature inside and outside the home.
How to Reduce the Cost of Running a Heat Pump
To reduce heat pump running costs in North Yorkshire, homeowners should focus on system design, insulation and tariff choice. Before installation, it is important to carry out a proper heat loss calculation so the system is sized correctly for the property.
You can help reduce running costs by:
- Improving loft, wall and floor insulation where possible.
- Using weather compensation controls.
- Keeping flow temperatures as low as practical.
- Choosing the right size heat pump for the property.
- Using suitable radiators or underfloor heating.
- Considering a smart electricity tariff.
- Keeping filters and outdoor units clean and maintained.
How Much Does a Heat Pump Cost Per Day?
If your heat pump costs around £4.70 to run for 12 hours, a full day of similar use could cost around £9.40. However, most systems do not run at the same power level continuously for 24 hours. Once the home reaches the desired temperature, the heat pump may use less energy to maintain warmth.
During milder weather, the cost may be much lower. During very cold periods, especially in older or larger homes, the daily cost may increase.
Are Heat Pumps Worth It in North Yorkshire?
For many homes in North Yorkshire, a heat pump can be a practical and efficient low-carbon heating option. They are especially suitable for well-insulated homes, properties off the gas grid, and households looking to reduce reliance on oil, LPG or older electric heating systems.
The key to good performance is not simply buying a heat pump, but making sure the full system is designed correctly. This includes the heat pump size, hot water setup, radiators, insulation and controls.
