An enquiry into green heating and insulation is being launched by the Competition and Markets Authority (CMA) – to ensure customers are treated fairly by businesses.

The CMA will quash misleading claims on cost savings, product performance and suitability to properties – as the public look to cut costs over the winter.

Concerns have been raised that consumers have a limited knowledge of newer green heating products and insulation and therefore can easily be taken advantage of.

Rooftop solar, heat pumps, biomass boilers and hydrogen boilers are being investigated specifically by the CMA.

Heating accounts for 17% of the UK’s carbon emissions so cutting this is considered critical by the government, however, it must be done in a way that protects the public, the authority maintains.

Sarah Cardell, the CMA’s Interim Chief Executive, said: “Reducing energy use is at the top of everyone’s agenda – be that because of rising bills, climate change or both.

“To help more people move to green heating and better insulate their homes, it’s essential that businesses understand and follow their legal obligations when selling and installing. That way, consumers can be confident they are being treated fairly.

That’s why we want to hear from consumers, businesses and other key groups about their experience now, so we can root out any problems early on and avoid them in future.”
