We still have a 25 year old back boiler and our gas and electricity direct debit has just gone up from £67 to £95 pcm. We're with Scottish Power.
Sorry - my heads all over the place at the moment, I should have put more background to my figures:
- 2 bed semi detached
mansion - sorry, house
- double glazed, cavity walls insulated, loft insulated to current recommendations
- room thermostat set to 18/19c
- 2 people
- heating on 2 hours in a morning and c6 hours in an afternoon/evening
......................the only reason our D/D has gone up dramatically is due to the extremely cold weather we had fairly recently and we ended up with a higher than normal debit balance on our last quarters bill.
If, given our antiquated (and allegedly high energy usage) back boiler equates to c£95 pcm, it seems outrageous that yours should be £250!!!
