A private swimming pool is a significant investment. UK costs vary enormously based on pool type, size, construction method and whether the pool is indoor or outdoor.
Running a 50,000-litre outdoor pool typically costs £1,500 to £3,000 per year in electricity, chemicals and maintenance. Heated pools cost considerably more to run. A pool heat pump uses less electricity than a conventional heater but still adds £600 to £1,500 per year to energy bills.
Outdoor in-ground swimming pools do not usually require planning permission as permitted development. However, if the pool is within 5 metres of the house, exceeds 50% of the garden area, or is in a conservation area or on a listed building, consent may be required. Pool enclosures and pool houses almost always need permission. Check with your local planning authority before starting work.
Pools require regular chemical balancing, filter cleaning, and annual professional servicing. Budget £800 to £1,500 per year for professional maintenance on a standard domestic pool. Most owners combine self-managed weekly chemical dosing with a quarterly professional service visit.
