I had a boiler fall through my cieling too. Funny thing is that they tried to pin it on me. Thats until I contacted the said boiler company to find out the warrantee is only 2 years ( because of the sand in the water). As the offending appliance was 5 years old and I presented these facts . They stood down. As I moved in with an expired appliance !!!
ps, I believe that the surplus of hard hats from all those in the buliding industry who have lost their jobs here will now be mandatory for all EGHQ staff. Ha ,they can see what it feels like to wear a hat !
