What does Keston receive a top rating for?

Because of Kestons’ lack of negative records, it receives a top rating for The Good Shopping Guide’s categories of Animal Welfare, Fossil Fuels and Nuclear Power.

Why does Keston receive a bottom rating for our Environmental Report category?

Keston’s parent company Groupe Atlantic has a CSR page. The page acknowledges ‘environmental challenges’ and also shares a CSR policy. However, the company does not mention any targets and there is only a small amount of information.

Because of this, Keston receives a bottom rating in this category.

What can Keston do to improve its score? 

Keston’s below benchmark score on The Good Shopping Guide’s Boilers Ethical Ratings Table is the outcome of an assessment of a variety of ethical criteria.

Although Keston does not currently meet the minimum ethical benchmark in the Ethical Boilers sector, The Good Shopping Guide still suggests that it gets in touch to apply for Ethical Accreditation. Once we have received Keston’s application, it will be offered some advice on how to improve its score and become a more ethical brand.
