Grenfell United and the TV architect George Clarke are calling on businesses and homeowners to take a “moral decision” and boycott the companies criticised in the Grenfell inquiry for “systematic dishonesty”.

Clarke, best known for his series George Clarke’s Amazing Spaces, said he had made the decision not to use products from Arconic, Kingspan and Celotex, three companies that were heavily criticised in the findings of the Grenfell inquiry published last year and who have continued to deny wrongdoing.

He lives close to the tower block in west London where 72 people were killed by the 2017 blaze which was fuelled by combustible insulation and cladding that did not comply with regulations.
