Do Air Source Heat Pump Grants Consider Electricity Cost Increases?

Home - Blog - Do Air Source Heat Pump Grants Consider Electricity Cost Increases?

When moving towards more energy-efficient solutions for heating homes, many people consider air source heat pumps. These systems are known for their environmental benefits and efficiency. Government grants often help cover the installation costs, making these systems more accessible. For instance, the government of the UK has introduced the Eco4 scheme; the greener scheme, under the Eco4 scheme, you can get a free grant for your heating system. All you need to do is check your eligibility here to apply for an air source heat pump grant. However, a crucial question arises: do these grants consider the potential increase in electricity costs? Understanding this aspect is vital for making an informed decision about whether to install an air source heat pump.

What is an Air Source Heat Pump?

An air source heat pump (ASHP) is a device that transfers heat from the outside air into a building. Even in cold weather, heat pumps can extract heat from the air and use it to warm your home. Here’s a basic overview of how it works:

Heat Extraction: The heat pump extracts heat from the outside air.

Compression: This heat is then compressed to a higher temperature.

Heat Distribution: The heat is distributed around the home via radiators, underfloor heating, or warm air convectors.

How Do Air Source Heat Pump Grants Work?

Government grants are available to help homeowners cover the cost of installing air source heat pumps. These grants aim to encourage the use of renewable energy and lower carbon pollution by making it easier for homes to afford to go green.

Potential Increase in Electricity Costs

Although air source heat pumps are efficient, they require electricity to function. Because of this, their cost of heating might go down compared to more standard ways like oil or gas, but it might still make your power bill go up a lot. The efficiency level for an ASHP has the Coefficient of Performance (COP), which means that if it has three, one unit of electricity makes three units of heat.”

Do Grants Consider Electricity Costs?

Grants for air source heat pumps focus primarily on the installation costs and the environmental benefits. They aim to reduce the upfront financial barrier for homeowners. However, they typically do not directly address the potential increase in electricity costs. Here are some key points to consider:

Installation Costs: Grants help cover the initial cost of purchasing and installing the heat pump.

Long-Term Savings: Because the heat pump works so well, heating bills will likely be lower for a very long time. This will help make up for the higher cost of electricity.

Effects on the Environment: The main goal of grants is to lower carbon pollution and support better energy sources.

Financial Considerations

Upfront Costs

The installation cost of an air source heat pump is usually between six and ten thousand pounds. Either a small or big part of these costs can be paid by the grants hence, and people will get motivated to adopt such forms of energy.

Running Costs

Grants help to reduce the initial cost, and instead, running costs matter a lot. Your bill depends on how efficient the heat pump is and how much the electricity costs. It is through electricity consumption that bills become expensive if the appliance is misused, although air source heat pumps are more efficient than traditional heating systems.

Benefits of Air Source Heat Pumps

Although there is the potential for higher electricity rates to be agreed upon, air-to-air heat pumps have a number of advantages:

  • Energy Efficiency: Typically, the total output of heat energy is greater than the electrical energy input.
  • Reduced Carbon Footprint: By using renewable energy from the air, they help reduce greenhouse gas emissions.
  • Lower Heating Costs: In the long run, the cost of heating will be the same as that of using gas energy.
  • Renewable Heat Incentive (RHI): The homeowner is able to get the heating system paid for by making sure that they produce heat through this scheme, known as RHI, thereby further enhancing monetary gains.

Real-Life Applications

Several things affect how cost-effective air source heat pumps are overall in homes that have them:

Grants: Many homeowners utilise grants to reduce upfront installation costs.

Energy Savings: In spite of higher electricity bills, net savings may occur due to the decrease in overall heating costs.

Environmental Benefits: Many homes gain a lot by lowering their carbon pollution and relying less on fossil fuels.

Tips for Managing Electricity Costs

To maximise the benefits of an air source heat pump and manage electricity costs, consider the following tips:

Improve Insulation: If you want to be sure that your heating works better, make sure that your house is well insulated. A well-insulated house will need less work from the heater pump.

Smart Thermostats: Tell smart thermostats how to change the temperature effectively while avoiding wasteful energy use.

Off-Peak Electricity: Utilise lower-priced energy when it is available to activate your heat pump at cheaper times.

Regular Maintenance: Always make sure that your heating pump is properly maintained so it can run as efficiently as possible.


The pros of an air source heat pump are lower initial costs and no direct rises in energy costs. The total cost depends on how well the heat pump heats or cools a home, how much power it costs, and how much energy the home uses. An air source heat pump may be worth the extra money in the long run, even though it uses more power. This is because it has better protection and cooler settings. It will become more popular for these systems as more people learn about how they can help homes use green energy. This is because they are good for the environment and the business. By looking at cost, efficiency, and impact on the environment, as well as grants, homes may be able to make an informed choice.
