FAQ's
How much does a swimming pool cost in London?
Outdoor liner pools start from £45,000 and concrete tiled outdoor pools from £60,000. Indoor pools within the main house start from £90,000, and basement pools from £125,000. See our Pool Prices pages for full breakdowns.
How long does a swimming pool build take?
A typical reinforced concrete pool build takes 8–16 weeks from groundworks to handover, depending on size and complexity. Basement pools and indoor pools with full ventilation systems may take longer. We'll give you a detailed timeline before work begins.
Do I need planning permission for a swimming pool in London?
In most cases, an outdoor pool in a rear garden can be built under permitted development rights. Indoor pools and basement pools may require planning consent. We advise on this during your initial consultation.
Which areas of London do you cover?
We work throughout Greater London and the South East — including Kensington, Chelsea, Wimbledon, Richmond, Hampstead, Mayfair, Northwood, and across Berkshire, Surrey, Oxfordshire, Hampshire, Buckinghamshire, Kent, and Essex.
Do you handle pool refurbishments as well as new builds?
Yes. We carry out full pool refurbishments including retiling, filtration upgrades, liner replacement, structural repairs, and outdoor-to-indoor conversions.
Do you work as the main contractor or alongside one?
Both. We can manage the full pool package and coordinate groundworks with your builder, or work under a principal contractor alongside your architect and structural engineer.
Why is your quote higher than another contractor's?
Compare the itemised lines. The difference is usually in the specification, such as a thinner waterproofing membrane, a cheaper tile adhesive or a single-speed pump, not in our margin.
