A private pool is no longer a rarity and, strangely, nowhere is this more evident than in Central London where there has been a huge increase in demand at all levels of the market.

Stuart Overington of Rainbow Pools notes:
In the past five years we've seen a tremendous surge in interest. We're not talking about the kidney shape pools you look down on when you land at Gatwick. Our London clients are very design and engineering-led. They want something sympathetic to their existing architecture, which will add to, rather than detract from, the value of their property.
Tom Tangney of Knight Frank recently completed the sale of a £28 million house in Holland Park that gave new meaning to the phrase 'lap of luxury'. Here, the indoor pool came complete with a full-sized film screen at one end:
At a certain level of the market it's almost become a question of not whether a house has a pool, but if not, why not.
A number of factors have contributed to this passion for personal pools. Partly, of course, the demand springs from the wealth inundating the best postcodes of Central London. The world's richest buyers - billionaires from India and China, Russia, Europe and the US - insist on a London base and are determined that their property comes with every toy. For many of these buyers, the paddling pool is an essential part of the playroom furniture. Brigitta Spinocchia of Candy & Candy confirmed:
It's become one of the USPs - like a view, lateral living or outside space.
But it's not just the excess funds that have powered the trend. The high cost of moving and the shortage of desirable property mean that many home owners are determined to make the most of what they have. For the time-pressured and the celebrated, having your exercise facilities on hand is preferable to the trek to a distant gym and, if swimming is your preferred sport, then even the smallest pool can be equipped with wave resistance to offer an effective workout.
Home pools are not just there for keeping fit. They reflect the expanding demand for the indulgent "spa exercise" to which owners have grown accustomed in luxury hotels.
Even in the rental market a pool can help a property to make a bigger splash. Katherine Scott of Cluttons, Wapping is marketing a three-bed penthouse in New Providence Wharf for £1,800 a week, with the tempting addition of a rooftop pool:
It's a spectacular flat with panoramic views of London, but the pool and sauna means we've been able to price it quite aggressively. Without the pool it would probably go for £1,500 a week, but the pool gives it that added wow factor. When you come here the pool and views take your breath away.
Factbox
According to The Swimming Pool and Allied Trades Association, prices for outdoor pools start at about £30,000, customised concrete pools at about £40,000. After that, keep counting: Rainbow Pools is creating a £750,000 indoor pool.
To save energy, cover up. Thermal bubble covers retain heat and can raise a pool's temperature by as much as 20F.
Heating and maintenance of an average pool costs about £500 a summer. Maintenance - testing and cleaning - takes about half an hour a week.
Unless your property is listed, you will not generally need planning permission for an outdoor pool.
