The Green Homes Grant has now closed

The RHI and Green Homes Grant Vouchers

If you have considered buying an air source heat pump, you have probably looked at the RHI (renewable heat incentive). With this Government incentive, you earn money for reducing carbon emissions and you are paid over 7 years.  Plus the benefit is multiplied because air source heat pumps are super efficient and so you could save ££££’s on your on-going heating and maintenance costs, with exact savings depending on your fuel type and lifestyle.

The new Green Homes Grant Voucher Scheme makes the switch from your existing system even more attractive. Rather than having to wait 7 years, the first £5,000 or £10,000 is paid immediately.

Easier to afford a better heating system

If you own your home in England and someone in the household is receiving benefits payments, then you can claim £10,000 for an air source heat pump system and installation. If you are a homeowner and no-one is on benefits, then you can claim up to £5,000. You can also claim the RHI for anything earned over the level of your Green Homes Voucher. So, if your voucher is £5,000 and you would ordinarily have earned £9,000 through the RHI, you can benefit from both Schemes, but your RHI payment would be £4,000.

An air source heat pump is a highly efficient way to heat your home and hot water.

Save money and carbon emissions

Air source pumps are an alternative way to heat your home  – replacing your gas or oil based system, for example.  They work like a ‘ fridge in reverse’, extracting free heat from the outside air, raising the temperature with a compressor and using that to heat water for a water tank and central heating system. Air source heat pumps can still extract heat when air temperatures are as low as -25°C.  The pump runs on electricity. Every 1kW of electricity produces 3kW of heat output which makes them a highly energy efficient way to  heat your home

Potential annual savings if you’re installing a standard air source heat pump in an average sized, four-bedroom detached home will be between 2,150 kg to 10,500 kg of CO2 a year/. £315 to £1300 a year, depending on the age and fuel type of your system.

Your questions answered

How do Air Source Heat Pumps work?

An air source heat pump works a bit like a fridge in reverse. There is an evaporator, a compressor and a condenser in the unit. The ASHP takes the free heat from the outside air which causes the refrigerant to evaporate (there’s enough heat even in winter to do this). Electricity drives a compressor that compresses the refrigerant and causes it to heat up. This heat is then transferred via a heat exchanger to central heating and hot water circuits. The cooler refrigerant now condenses back into a liquid and starts the cycle again.

Is an Air Source Heat Pump right for my home?

An air source heat pump requires little maintenance, is super efficient and easy to install. They are perfect for homes heated with older gas boilers, oil or electricity – because the cost (and carbon emissions) savings are so significant. Give us a call or fill in our online form, and we’ll have a proper look at your home and what could be right for it.

How much will I need to spend?

The answer is ‘it depends’ but it could be free!

The cost of an air source heat pump and its installation is down to a number of factors including the size of your home, the manufacturer of the system, and your existing radiators and pipes. If you are eligible for a £10,000 voucher, that could cover all of the costs of the works.

Will I save money?

The amount of money you will save depends on what type of heating you have now, your home and your lifestyle. If you have an old LPG system, you could save £1300 each year – huge. When we do a full technical survey, we calculate costs and savings – so you’d never be going ahead with something without having proper information.

How big is an air source heat pump?

It will depend on your home and the size of the system you need.  Once we have done the calculations, we’ll let you know what to expect. As a ‘starter for ten’, think of a standard air conditioning unit.

I am on a low income – can I apply for a grant?

In short, yes. Regardless of your financial position and your household income, homeowners in England can apply for Green Homes Grant and receive the funding needed to make their property more energy efficient and more comfortable to live in. Not only that, but you could see the value of the property itself increase as a direct result. Note that if you are a homeowner with a household member on certain benefits, are eligible for a £10,000 grant to cover 100% of the costs of green home improvements.

Will I be means tested for a Green Homes Grant?

If you are a homeowner in England and anyone in your household is on benefits (as listed above), you qualify for a £10,000 grant. If you are a homeowner in England but with no-one on benefits, you qualify for a £5,000 grant to cover two-thirds of the cost of ‘green’ improvements (with you contributing a third).

How to apply for an Air Source Heat Pump grant on benefits?

Register today with HomeSun for your Green Homes Grant voucher, to get you and your property on the way to enjoying an air source heat pump. If you are a homeowner with a member of your household on benefits, your £10,000 voucher should cover the cost of the heat pump and installation work.
