How Much Does a Pool Cost in the UK? 2026 Price Guide

The installation is a one-off. The water is a standing order. Any pool quote should be read next to a realistic figure for what the thing costs to run every year, because in a British climate that number is not small and it never goes away.

What follows is what installers are charging in 2026 — not brochure teasers — broken into unit costs, split between labour and materials, and tested against three real jobs. VAT at 20% is included throughout, because domestic pool work attracts no reduced rate.

Pool pricing is bimodal. There is the few-thousand-pound world of above-ground pools, and the thirty-thousand-and-up world of anything with concrete in it. Almost nothing exists in between, and the gap is groundworks.

• •Above-ground steel or resin frame, 3.6m to 5.5m: £250 to £1,600 for the pool, but £900 to £2,500 all-in with a hardcore-and-slab base, a decent sand filter and an outdoor RCD socket.
• •Above-ground pool sunk into decking: £6,000 to £14,000.
• •Block-and-liner in-ground pool, 8m x 4m: £32,000 to £55,000 installed.
• •One-piece GRP (fibreglass) shell, 6m to 8m: £35,000 to £70,000, more where a crane is needed.
• •Sprayed concrete, fully tiled or mosaic: £70,000 to £140,000.
• •Natural swimming pond with regeneration zone: £45,000 to £110,000.
• •Indoor pool including building shell, air handling and dehumidification: £150,000 to £350,000.

Ask for an itemised quote and these are the numbers you should see. They are per unit, so you can scale them to your own pool rather than trusting a lump sum.

• •Excavation and muck-away: £45 to £75 per tonne. An 8m x 4m pool at 1.0m to 1.8m depth throws out 90 to 130 tonnes, so £4,500 to £8,500 before a block is laid.
• •Reinforced slab and blockwork shell: £280 to £420 per m² of wetted area (floor plus walls) — £11,000 to £16,000 on that 8m x 4m.
• •Printed 0.75mm liner: £2,400 to £4,500 fitted. Reinforced 1.5mm liner: £5,500 to £9,000.
• •Coping stones: £70 to £160 per linear metre laid; a 24m perimeter is £1,700 to £3,800.
• •Plant kit — sand filter, 1.1kW pump, skimmers, returns, pipework: £3,200 to £6,500. A brick or GRP plant housing adds £1,500 to £5,000.
• •Air-source pool heat pump, 12kW to 17kW inverter: £2,000 to £4,200 supplied, plus £600 to £1,400 to fit and commission.
• •Electrical supply, RCD protection and equipotential bonding by a Part P registered electrician: £900 to £2,600.
• •Covers: bubble/solar £150 to £500; manual safety cover £1,400 to £3,200; automatic slatted cover £7,000 to £15,000.
• •Surround paving: £85 to £150 per m² supplied and laid, so 40m² is £3,400 to £6,000.

On a block-and-liner build the split lands near 55% labour and plant hire against 45% materials. A one-piece GRP pool flips it — the shell is one large material cost, so you are nearer 45% labour and 55% materials, which is why fibreglass looks cheap on paper and rarely finishes cheaper once access is priced. An above-ground pool is 85% materials, and that is its entire appeal.

The rates behind the labour half are worth knowing: a two-man pool crew is £380 to £520 a day, a 3-tonne excavator with operator £280 to £380 a day, a grab lorry £280 to £420 per 16 to 20-tonne load. An installer who cannot tell you roughly how many crew-days the build takes has not priced it, only guessed it. The questions in our guide to what to ask a contractor transfer directly.

Two identical pools thirty miles apart can differ by £15,000, and almost none of that is in the water.

• •Access. If a 3-tonne digger reaches the hole, you sit in the lower half of every range. Wheelbarrow-only access down a side passage adds £3,000 to £7,000 in labour. A crane lift over the house for a GRP shell is £1,500 to £3,500 plus any road closure.
• •Ground conditions. Clay is slow, running sand needs shuttering, and a high water table means a dewatering pump at £400 to £900 a week plus a hydrostatic relief valve. Rock is the expensive surprise.
• •Shape and depth. A constant 1.2m depth is cheapest; a 1.0m to 2.0m slope adds spoil and blockwork, and a freeform outline adds 10% to 15% in labour.
• •Finish. Full tiling over a liner adds £250 to £450 per m² of wetted area — often £15,000 to £35,000 on its own.
• •Extras. Counter-current swim jets £3,500 to £9,000; LED lights £350 to £900 each; automatic dosing £2,600 to £5,500.
• •Region. London and the Home Counties run 15% to 25% above Midlands and northern pricing for the same spec.
• •Consents. An outdoor pool in a rear garden is usually permitted development, but listed buildings, conservation areas and any enclosure or indoor pool change that — check when you need planning permission and building regs before ordering anything.

Composites of real 2025 and 2026 jobs, rounded to the nearest £50.

• •Leeds, 4.5m above-ground steel frame. Pool £850; hardcore and slab base £900; upgraded sand filter £280; solar cover £120; outdoor RCD socket £320; starter chemicals and test kit £160. Total £2,630.
• •Hampshire, 8m x 4m block-and-liner, good side access. Design and setting out £900; excavation and muck-away £5,800; slab, blockwork and render £11,500; liner and coping £6,400; plant room and filtration £4,900; 14kW heat pump fitted £3,600; electrics and bonding £1,800; 40m² porcelain surround £4,600; manual safety cover £1,900; commissioning £500. Total £41,900.
• •Surrey, 7m x 3.5m GRP shell, crane access only. Shell £16,500; crane and traffic management £2,400; excavation and off-site disposal £6,900; concrete backfill surround £3,800; plant £4,200; heat pump fitted £3,900; electrics £2,100; 35m² paving £4,900; automatic slatted cover £9,500. Total £54,200.

This is the section that changes minds. Figures assume an 8m x 4m outdoor pool held at 28°C from May to September, electricity at 26p per kWh, and a cover pulled over every night — that habit is worth more than any efficiency measure you can buy.

• •Heating with a modern inverter heat pump: 3,000 to 5,000 kWh a season, so £780 to £1,300. Leave the cover off and it roughly doubles.
• •Circulation pump, eight hours a day for five months: £70 to £140 variable-speed, £250 to £450 with an older single-speed unit.
• •Chemicals — chlorine, pH minus, stabiliser, algaecide, test strips: £250 to £600 a year.
• •Opening and winterising by a service company: £250 to £450 each. The freeze logic in our frozen pipe guide applies to pool pipework and skimmers too.
• •Liner replacement every 8 to 12 years at £3,000 to £6,500 — set aside £400 a year.
• •Heat pump replacement at 10 to 14 years: £3,000 to £5,000. Insurance uplift: £50 to £150 a year.
• •Realistic annual total: £1,300 to £2,600 outdoors, £3,500 to £7,000 indoors where dehumidification runs all year.

The cheapest quote in a set of three is rarely cheaper work — it is a shorter scope. Nine times in ten the missing lines are muck-away, the surround and the electrical supply, all of which land back on you at full price later. Get three itemised quotes, compare line by line, and treat anything more than 25% below the others as incomplete until proven otherwise. If a quote fails two of the checks below, keep looking, and read our list of contractor red flags first.

• •Every stage itemised: excavation, disposal, shell, liner, plant, electrics, cover, surround, commissioning.
• •No blanket exclusions such as 'spoil to remain on site', 'power supply by others' or 'surround by others' unless you have separately priced them.
• •VAT shown, not appended in the small print.
• •The installer names the heat pump model and kW, the filter turnover rate (the whole volume should pass through in four to six hours) and the pipework diameter — 50mm on anything over 6m is under-sized.
• •SPATA membership with a SPATA Shield warranty, and a named Part P registered electrician.
• •Payments staged against milestones with a 20% to 30% deposit. Above 50% up front is a hard no.
• •Ground conditions covered by a stated provisional sum, not an open-ended 'subject to site'.
• •Methodology: figures come from itemised installer quotes across England and Wales in late 2025 and early 2026, current UK retail pricing for pools, filtration and heat pumps, and running-cost modelling at 26p per kWh, all inclusive of VAT. Treat them as spring 2026 bands and re-check before committing — the same drift we track in our UK home maintenance cost guide.
