Have purchased a house for residential use which comes with an outdoor swimming pool built around 30 years ago, original boiler, pipework, etc. Considering the cost of energy at the moment, the number of hot days we get in this country and the likelihood of much of it needing replacing, I am thinking of decommissioning it, filling it in and covering it over - does anyone have any experience of the likely costs and other important considerations in doing such a project?
