Did you do a comparison on prices. I went to Curry's and looked at a cheapo oven but the Curry's website was £75 cheaper
. Ended up getting it a bit cheaper at AO online. i don't think you'll save much on fuel bills but probably heats up a lot quicker
Alternatively, if you don't want a pristine one/ don't mind some marks on it, some do outlet specials with warranty. Did a check on a Hotpoint (don't know if any good and only one fan oven)
Curry's - £439

£360 (if you take out the Which £1 offer)

Outlet Store - £185 (if you take out the Which £1 offer)

That said, even £185 of takeaways will probably save you more on the leccy bill
