Do you have a swimming pool? I need an idea of running costs for indoor pool

[ThisIsJustASagaNow]

We're thinking of moving. There's a house we like a lot, but it's got an indoor pool; all beautifully done etc from what I can see. We weren't looking for a house with a pool though.

It's both an attraction and a deterrent in equal measure. Well more of a deterrent if I'm honest. I suspect the running costs are going to be the deciding factor.

Can anyone give me a rough idea of annual costs re heating and maintenance of pools please? I have no clue.
