Meet your local South West Scotland installer

Meet Stewart Temperature Solutions, Our Local Partner for OVO Solar and Heating South West Scotland

When we went looking for a partner in South West Scotland, we wanted a business that had already earned its reputation. Stewart Temperature Solutions has over 30 years in operation, with 5 years specialising in solar and heat pumps, and had been trading in Ayr long before OVO Solar and Heating was involved.

Based in Ayr and led by Managing Director Gregor Stewart, the business runs a showroom customers can visit, trains its own apprentices locally, and won a Scottish Renewable Installation of the Year award at the Energy Efficiency Awards 2025/26. The team is also involved in CARES grant work and sponsors Ayrshire radio and Ayr United Football Club, the kind of everyday local presence that matters to our customers.

Our chosen local partner: Stewart Temperature Solutions is our local partner for South West Scotland. Working with a local business keeps the job, and the income, inside the community they serve, and you’ll deal with the same team throughout, from your first call to survey, installation and aftercare. They also carry the backing of OVO Solar & Heating, a major national brand, with extended workmanship warranties, flexible financing and Smart Export Guarantee rates, so you get a team who already knows the area, backed by a name you can trust.

Local knowledge

Ayrshire’s homes, from coastal cottages to Victorian sandstone terraces, come with their own quirks, and understanding them is exactly the kind of local knowledge a national-only installer doesn’t have.

What the team offers

Stewart Temperature Solutions designs every solar PV system around your household’s real energy use, not a generic package, so your payback period reflects your home and your habits. Battery storage can be added alongside, letting you store the power your panels generate during the day and use it in the evening, cutting your reliance on grid electricity when demand and prices are highest.

On the heating side, the team’s award-winning work speaks for itself: one standout project combined an air source heat pump for hot water and underfloor heating on the ground floor with ducted air-to-air heat pumps upstairs, giving both heating and cooling in the same system. That same air-to-air technology means air conditioning is also on the table for customers who want it, with the team happy to talk through what fits your property.

Frequently asked questions about solar and heat pumps in South West Scotland

How much does an installation cost, and what does the process look like?

Costs depend on your property, system size and current energy setup, so the team gives every customer a fixed quote after a free, no-obligation survey rather than a generic price list. For solar, a typical domestic installation takes one to two days once scheduled. Heat pump installations usually take longer, since they often involve pipework or electrical upgrades alongside the unit itself, and the team will walk you through a realistic timeline specific to your home before any work is booked in.

Are there any grants available?

Scottish homeowners may be able to access grants and interest-free loans through Home Energy Scotland towards solar, battery storage and heat pump installations. The scheme is designed to bring down the upfront cost of switching to renewable technology, though eligibility, amounts and the application process can change. The team can talk you through what you’re likely to qualify for as part of your survey, and it’s worth checking the current details on the Home Energy Scotland website too.

What does the warranty cover?

Solar installations carry a 10-year workmanship warranty, covering the quality of the installation itself rather than just the equipment. On top of that, the solar panels, inverter and any battery come with their own manufacturer’s warranties, which vary by product and are usually longer than the installation warranty. Heat pump installations are covered by a 5 year warranty plus the manufacturer’s warranty, the specific terms of which the team will confirm for your system before you sign anything.
