English speaking gentleman was very nice to talk. But on the other hand wonted me to have a gas money saving machine fitted to my boiler. Couldn't give any more info on this so is it a scam as other story's different with same phone number. Also told me there based in Doncaster...

Called 16 Jul 2018 17:34 when I was out. Left no message.

Derbyshire based company trying to con me into buying some form of air-exchange booster mechanism that will save me lots of money on my heating bill. Unable to answer even the simplest questions as to how their 'system' works. If they telephone a scientist they must expect to be flattened by scientific expertise :)
