The short answer
Swimming pool costs cover a very wide range. A professionally installed above-ground pool typically costs around £5,000–£10,000. An in-ground outdoor pool usually runs £30,000–£100,000+: a modest fibreglass pool around 8m × 4m can be roughly £25,000–£40,000, while a larger 10m × 5m fibreglass build is commonly £55,000–£80,000, and a tiled concrete pool can reach £80,000–£100,000+. An indoor pool is typically £85,000 to well over £200,000 because it also needs a building, ventilation and dehumidification. The main drivers are pool type, size, shell material, ground conditions and where in the UK you are.
Price depends mainly on the type of pool, its size and shell, how difficult your ground is to dig and service, and your region. The figures below are typical installed prices for guidance, not quotations.
Typical UK costs
- Above-ground (installed)~£5,000–£10,000
- In-ground fibreglass 8×4m~£25,000–£40,000
- In-ground fibreglass 10×5m~£55,000–£80,000
- Tiled concrete pool~£80,000–£100,000+
- Indoor pool~£85,000–£200,000+
What drives the price
- Pool type: above-ground is the lowest-priced route; in-ground costs far more; indoor adds a building on top.
- Size & shape: you largely pay by the volume of water and the dig, so a 10m pool costs well above a compact plunge pool.
- Shell material: fibreglass (one-piece), vinyl-liner and tiled concrete sit at different price points and lifespans.
- Ground & access: rock, a high water table, slopes or tight access all add excavation and groundworks cost.
- Region: labour around London and the South East typically costs more than the North.

| In-ground fibreglass 10×5m | ~£55,000–£80,000 | larger family pool |
| Tiled concrete | ~£80,000–£100,000+ | bespoke, longest-lived |

Why the range is so wide
Unlike a fixed product, a pool is built to your garden, so two homes can get very different quotes for the same brief. A flat, accessible plot with stable ground keeps groundworks low; rock, a high water table or a steep slope can add tens of thousands. Finish matters too — a one-piece fibreglass shell is quicker and often lower in cost than a hand-built tiled concrete pool, which is the most bespoke and longest-lived option. Heating, covers, paving and fencing are usually extra, so always check what a quote does and does not include.

Why is the price range so wide?
Because a pool is built to your site. Pool type, size, shell, ground conditions, access and your region all move the number. A site survey and measured quote gives the accurate figure for your home.
