Switching to renewable energy or upgrading your home can feel like a big step. Below you will find clear, smart answers to the most common questions about our services, grants, and how it all works.

Air Source Heat Pumps (ASHP)

Yes – modern air source heat pumps are designed to work efficiently even in cold conditions, including Scottish winters. They extract heat from the air even at -15°C.

Not always. Some homes will need larger radiators or underfloor heating to get the best results – we will assess this during your survey.

The Energy Saving Trust provide useful information on the potential annual savings. You can take a closer look by visiting their website.

You may qualify for the Boiler Upgrade Scheme (BUS) or Home Energy Scotland (for households in Scotland) which offers £7,500 towards an ASHP install subject to eligibility criteria.

Solar PV Panels

Absolutely. They work best in direct sunlight but still generate electricity on cloudy or overcast days – just at a lower rate.

East or west-facing roofs can still work well. We will assess your orientation and shading to give you a performance estimate.

According to the Energy Saving Trust solar panels typically last 25-30 years. Most systems have manufacturer warranties and minimal maintenance requirements.

Yes – with a smart meter and SEG (Smart Export Guarantee), you can earn for excess energy sent back to the grid.

Battery Storage Systems

Yes. We can retrofit batteries to many existing systems to help you store and use more of your own energy.

Some battery storage systems offer backup functionality – we will advise you on which models include this feature.

EV Charging Points

Yes, we install home EV chargers for all major electric vehicle types. All installs are carried out by OZEV-approved electricians.

Ideally yes – but we can advise on safe options for properties without driveways too.

In some cases, yes – especially for landlords or flat owners. Ask us and we will check eligibility criteria for you.

Insulation Services

We offer loft insulation, cavity wall insulation, internal and external wall insulation – all compliant with current regulations.

According to research from the Energy Saving Trust – up to 35% of heat loss can be through uninsulated walls, and 25% through the roof.

Inspections & Repairs

Yes. We can inspect and repair most renewable energy systems, even if we did not install them.

We recommend an annual check-up to keep everything running efficiently and within warranty guidelines.

Funding & Grants

A government scheme that offers a £7,500 grant for installing an air source heat pump (subject to eligibility).

ECO4 offers fully or partially funded upgrades (like insulation, new heating systems or smart controls) to homes that are expensive to heat. You may qualify if your home has a low EPC rating and you receive certain types of support.

Yes, we can provide guidance on the various funding options and the grants that you could be eligible for.

FAQs for Scotland

Yes. All systems we install are selected and tested for cold UK conditions, including northern and highland areas.

Yes – we install across much of Scotland, including Ayrshire, Glasgow, Edinburgh, Fife, Dundee, Aberdeen, and parts of the Highlands.

Yes. Our Kilmarnock-based team offers in-person surveys across Scotland.
