Cowboys! Do NOT use - these are unqualified people who are out to cheat vulnerable people! I have now contacted the FOS. Elderly parents were told that if they had underfloor insulation they would get a subsidised bolier (part of ECO scheme) - we stated that our flooring was newly done and we did not want any damage, they promised they would do a tidy job. the man they sent (Luke) admitted he was contracted out and didn't have that much experience in this specific work. he started to pull the floor boards, realised that he had damged the property and ran away! I called Kenneth (the so called manager) and stated that i expect this to be fixed. Sent several emails, called numerous times (only to have 'Adam' hang up on me and not call back). Treated with total disprespect and distain.... To this day nothing - my parents have been in a cold room since Jan 2020!!!! these are evil people - do not use. i have contacted the FOS and await an investigation. DISGUSTING service.
