We have a Baxi Instant 105E and only use the preheat for 5 minutes before we wash the dishes or use the sink upstairs - this is additionally driven by having had a water meter installed - takes 4 litres of water down the drain to get hot upstairs. 3 bed 2 storey house, built 1995, double glazed with HUGE conservatory, loft insulation, builders 1" pink foam cavity insulation (looking at getting that upgraded!), end of terrace. Disabled wife who cannot be allowed to get cold - cos she hits me with her walking stick when temp goes below 20deg. EBICO is gas supplier. Gas bill for quarter ending 7 October 2013 - GBP11.91p. (Oops, got my 5s and 9s mixed up!)
PS - meant to also include that since April have paid GBP40.00p per month direct debit (as you do) and currently sitting on GBP230.00p credit, most of which will transfer to cover electricity bill - we have fishpond with pumps and filters on 24/7 so always have been a high(ish) leccy user but having solar panels installed next week to take care of that (for daylight hours anyway!)
