Why bother doing stuff for them. Leave it let them fall behind. Then beg for engineers the rates and conditions will hopefully get better. That includes people subbing to homeserve and corgi. Homeserve have heavily invested in the parent company of corgi.
Wasnt up to me I worked for someone back then. I wouldnt do it now though. It was hard work but i think my boss screwed me over as i was getting 7/8 back boilers a day or all boilers and fires all over brum so had to fly around.
