Here's a picture of the Flue and the window, all as was when house was built! The report doesn't actually list what the readings were, just that it failed, but readings were all perfect in February!

Bet the BG engineer did not leave old valve with you !!
So no proof that it was wrong valve, would have been under orders not to leave any evidence, have you thought about changing insurance cover
They do not guarantee the system will never get sludged up after they flush. What they guarantee is after they do a flush and you have re-occurring circulation issues they will re-flush as required without charge.this man talks sense i was on a job doin maintenace and a gb engineer was fault finding on a boiler he didnt have a clue it was a system boiler installed and he thought it was a combi what a div i know its about having peace of mind with those covers but i dont think its worth the paper its written on just like any insurance they have always got a get out clause use the independant when u need to they also quoted a friend of mine 600 for a powerflush and stated it had a lifetime guarantee wot a load of cobblers how can u guarantee no sludge or scale for life especially in london
