My Edinburgh house is 25 years old and still on the original gas boiled (though a bit like triggers broom in that pretty much all of it has been replaced over the years) but I think I'll replace it with a gas combi boiler while I still can, as the costs of converting it to effectively use an air source heat pump would be astronomical.
My cottage in the Highlands had a new oil combi boiler last year so should be fine for quite a while, which is just as well given I reckon it'd cost £30-35K to convert that to a ground source heating system (with a lot of that cost being very disruptive works in the house itself - insulation and underfloor heating) which isn't likely save more than a few hundred pounds a year (if that).
