Aventus Eco is a renewable energy installation company serving homeowners across Scotland, with offices in both Glasgow and Edinburgh. The company specializes in air source heat pumps, solar PV panels, and battery storage systems—essentially everything a homeowner needs to move away from gas heating and start generating their own electricity. For Scottish households dealing with rising energy costs and increasingly unpredictable winters, this type of service has become more relevant than ever.

The company holds several industry certifications that matter in this field. They're MCS-accredited, which is required for customers to access government grants and ensures installations meet national standards. They're also Heat Geek certified, a training program focused specifically on heat pump design and optimization. TrustMark registration adds another layer of consumer protection. As a reviewer, I'd note that these credentials aren't just marketing badges—they directly affect whether customers can claim the £7,500 to £9,000 in grant funding available through Home Energy Scotland.

Heat pump installation forms a core part of what Aventus Eco does. Unlike some installers who take a one-size-fits-all approach, the company emphasizes custom system design based on actual heat loss calculations for each property. This matters quite a bit because Scotland has a lot of older housing stock—stone cottages, tenements, Victorian-era homes—that present unique challenges for heating systems. A heat pump sized wrong or poorly configured will struggle to keep a home warm and end up costing more to run than it should.

Solar PV and battery storage round out the service offerings. The company installs panels on various roof types and pairs them with battery systems that store excess energy for use during evenings or cloudy days. One customer testimonial on their site mentions going from £600 monthly energy bills down to £25 after getting a solar and battery setup installed. That's a dramatic reduction, though results obviously vary depending on the home, energy usage patterns, and system size.

What sets Aventus Eco apart from larger national installers, in my opinion, is their approach to aftercare. They use only in-house engineers rather than subcontractors, and customers get direct WhatsApp access to their installer after the job is done. The company includes a free three-month check-up visit and provides lifetime monitoring for both solar and heat pump systems. A 5-year workmanship guarantee covers their installation work, while manufacturer warranties extend up to 7 years on equipment.

The company also handles heat pump servicing and repairs, including fixing systems that were poorly installed by other firms. This rescue service for underperforming systems suggests they've seen their share of botched installations in the market—a common problem in an industry that's grown quickly and attracted some less experienced operators. Their Heat Geek certification specifically trains engineers to diagnose and optimize heating systems that aren't working as they should.

Aventus Eco's process starts with a free home energy survey where they assess insulation, layout, and run heat loss calculations before recommending any equipment. They then provide a clear quote showing system costs, applicable grants, and financing options. For Scottish homeowners considering the switch to renewable heating, the company offers a locally-based alternative to the big national players, with a technical focus that prioritizes getting systems right rather than just getting them installed.
