Will I save gas by turning my boiler stat down ?

So are there are savings to be made ? Al tries to explain all.
If you need any plumbing parts here is my Amazon shop link. http://www.amazon.co.uk/shop/dereton33
Saved money on plumbers coming out? Want to donate a £1.00 and keep our spirits up? Here is the link. http://www.dereton33.com/page118.html
Many thanks Al and Jan.
