At SolarTherm UK, our commitment to sustainability extends far beyond the renewable energy systems we install. Every residential customer we serve receives a HIES Insurance Backed Guarantee, a safeguard designed to protect homeowners with trusted consumer protection. Many customers however, do not realise that this guarantee also helps power something even greater: the planting of a tree for every SolarTherm UK residential installation.
A Partnership That Makes a Real Difference
Through HIES and their collaboration with JUST ONE Tree, each policy issued triggers the planting of a tree. This means that since our registration with HIES, SolarTherm UK and our customers have effectively planted over 4,000 trees – each one represented with an official planting certificate.
This initiative aligns perfectly with our mission to reduce carbon footprints, promote long term environmental health and give homeowners an opportunity to make a positive global impact simply by choosing a reputable, sustainable installer.

Quantifying Our Environmental Contribution
Trees remain one of the most efficient tools available for capturing carbon dioxide and improving air quality. On average, each tree absorbs approximately 21kg of CO₂ every year. Thanks to our customers choosing SolarTherm UK and benefiting from our HIES backed protection, the resulting environmental impact is measurable and significant.
Our impact so far:
- 4,000+ trees planted
- 21 kg CO₂ absorbed per tree per year
- 78,120 kg of CO₂ offset annually
This is the equivalent of:
- Removing emissions of over 170,000 car miles
- Offsetting the annual electricity consumption of dozens of UK homes
- Contributing meaningfully to global reforestation in regions where it is needed most
These aren’t abstract numbers, they are tangible, positive outcomes created through every SolarTherm UK customer partnership.
Why This Matters
Reforestation is one of the most effective strategies for combating climate change. By planting trees in degraded or deforested regions, JUST ONE Tree supports ecosystems, biodiversity and local communities. Through our involvement in this initiative, SolarTherm UK ensures that every installation contributes not only to cleaner energy but also to a healthier planet.
Our customers can take pride knowing that their renewable investment continues to deliver benefits far beyond their own property, advancing environmental restoration and global sustainability.
A Greener Tomorrow, One Installation at a Time
SolarTherm UK is proud to play a role in this critical mission. As we continue to grow, so does our environmental contribution, one residential project and one newly planted tree at a time.
