HomeSun and You

What will HomeSun do?

HomeSun works with homeowners, landlords and property management companies. We assess the best fit technology or system for a property, produce a quote and then install to best standards. If we think that what you need is something we do not currently offer, we will introduce one of our selected network partners. The idea is to make this easy for you.


The idea is to make this as easy as possible for you.

What about grants?

The Government has made a commitment to reduce the country’s carbon emissions. It’s amazing but around 20% of emissions are creating by heating buildings! So, to help achieve the UK target, the Government has put in place various financial incentives to get homeowners to switch to low carbon heating. Some of these are difficult to find or apply for. We help with that.

Do you guarantee your work?

We provide all the relevant guarantees for our work. Park Home insulation for example, comes with a 25 year CIGA guarantee.

Green Homes Grant

What was the Green Homes Grant Voucher?

The Green Homes Grant Voucher Scheme ran from October 2020 through to March 31st 2021. It gave grants of £5,000 and £10,000 towards low carbon home improvements. HomeSun was accredited as a Green Homes Installer and we focussed on Park Home Insulation and Air Source Heat Pumps.

What happens if I have a Green Homes Voucher?

If HomeSun is your registered installer, give us a call once you have your voucher and we can get things moving. If we are not your registered installer, HomeSun may still be able to help – just give us a call.

Can you be my Green Homes Installer?

We install Park Home Insulation and Air Source Heat Pumps. If you’re looking for those, give us a call!

Air Source Heat Pumps

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 tend to be 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 financials depend on your home and what type of heating you have now. If you have an old LPG system, you could save £1,300 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.

Park Homes

What can you insulate?

Walls and underfloor. The insulation traps the heat inside your home, preventing it from escaping through your walls, so your heating bills are lower. External wall insulation will also improve the appearance of your property!

What other benefits are there from external wall insulation?

  • Stops draughts
  • Gives you a constant temperature – because you aren’t loosing heat through the walls
  • A cooler home in summer – traps cool air inside
  • Increased comfort – the constant temperature means you don’t have to keep fiddling with the thermostat
  • Removes chilly damp atmosphere that can build up in a colder Park Home
  • Helps to eradicate damp, mould and mildew
  • Gives you total weather protection
  • Improves sound resistance – reduces noise from outside and helps privacy because it will muffle your sounds too
  • Easy and low maintenance with a 25 year guarantee
  • Looks fabulous

Cavity Wall Insulation

What is a cavity wall?

The external wall of a house is constructed of two masonry (brick or block) walls, with a cavity and held together by metal wall ties.

Are all houses suitable for cavity wall insulation?

No. There are many homes which have solid brick walls and they need different treatment. If the house is not of traditional construction, it is unlikely to be suitable. This would include a timber frame, for example, and stone.

How will I know if my house is suitable?

You can often tell by the brick pattern…

But don’t worry. We will send a surveyor to assess your property. This will involve a drilling a small hole and inserting a borescope (like an in-wall camera).

Will the drilling make a mess of my walls?

Our installers will fill any holes with mortar to match the existing finish as closely as possible.

Is there a guarantee?

Yes. Cavity & external wall insulation come with an independent 25 year guarantee.
