4 suggestions to save money.

1) Electric Halogen oven.
£30 from Aldi, with a 3 year warranty (keep the receipt).
Basically a turbo fan oven in a glass bowl. Very fast to warm up.
1400 W rather than 3500W for a full oven. Has been measured to use less than 40% of the energy of my fan oven, over the entire cooking cycle. And faster.
Easy to clean. Ideal for one person, or two with smaller appetites.

2) A dessicant based dehumidifier, such as the highly recommended Meaco DD8L. (~£250). Very effective at lower temperatures, such as caravans, garages and R75s.
Keeps the house dry, significantly reduces heat loss by keeping walls drier. Stops all damp on windows, except under extremely cold weather.
Absolutely no mould ever again.
Only ever runs when needed.

3) Marry a Yorkshire lass (without a deadly right hook) !
(Preferably not Mrs Delphine Featherstone, the Black Widow!)

4) Treat her to a fur coat. Then you can turn the heating down when you go out, and she won't freeze...
