Urgh: what a horrible site. Who decided to display PDFs in a window 
occupying less than half the screen area? And couldn't a UK government 
department manage to get more than one of the links to other gov.uk 
pages to work?! The Energy Consumption in the UK doc was the only one 
that worked: 5 other links gave Page Not Found!

As far as I got (I stopped before answering a bunch of questions I 
didn't have enough information to give an informed response to) I 
couldn't find anything on the payback time of weather comp. But they say 
they estimate that replacing standard- with high-efficiency boilers from 
2005 onwards (for a change from SEDBUK c.80% to c.90%) resulted in 
average savings of around £95 a year, suggesting that if weather comp 
improved SEDBUK by a couple of percent it would have to cost around £200 
to take > 10 years to pay back (at current near-zero interest rates but 
this is just an OBOE estimate).

Don't suppose you have a copy of the PDF?

cheers
