The Cost of Swimming Pool Installation

TL;DR The cost of swimming pool installation varies widely based on shape, size and equipment required however a ball park figure for a basic swimming outdoor swimming pool is £50,000 going up to £100,000+ for larger, and better equipped pools. The cost of swimming pool installation for indoor pools start at £70,000 for a basic pool and equipment ranging to £130,000+ for larger and higher spec pools. It is recommended that you get a free consultation and site survey from us to fully understand your requirements and get you an accurate estimate.

Having a pool installed at your property is a big investment. It is also possibly the one of the best purchases you can make to improve your quality of life at home and improve family enrichment. There are many considerations to purchasing a swimming pool that need to be considered which affect the cost of swimming pool installation. The different swimming pool construction methods come with different features and considerations. Choosing the right pool construction type that is right for you should be the first priority when asking the question of how much a swimming pool costs. Swimming pools can be built indoors and outdoors, each comes with different equipment and costs associated. Naturally, if you desire an indoor pool, you will need a building to house the pool which comes with it’s own cost as well as paying for the pool itself.

Other factors that should be considered which affect the price of a swimming pool are:

  • Size
  • Shape
  • Features – lighting, water features, covers

Swimming Pool Size

By far, the biggest cost of swimming pool installation is the size of the pool you want. The average UK swimming pool measures 9.2m x 4.5m (or 30ft x 15ft) This size of pool gives the owner enough length to swim for exercise and enough width for children to play games. Some pool owners prefer to use their pool purely for exercise and therefore opt for a longer thinner pool around 20m x 2m ( or 65ft x 6.5ft) which allows you to swim a decent length. This style of pool is known in the trade as a lap pool as you swim laps back and forth.

The question you need to ask yourself (and family) is what is the purpose of the pool? Is it: exercise, children, entertainment, relaxation, sanctuary? The answer to this question should offer you an idea of the approximate size you might want. It may also be useful to look at swimming pools around the size you think you would like. The idea of a 25m x 10m pool maybe a dream but you soon realise that this size is not to dissimilar to a small leisure centre and the cost of installation along with the ongoing costs to maintain such a body of water is simply unrealistic in a domestic environment.

One other consideration to the size of your pool should also be the size of your pool surround. The pool surround is typically 1.5m – 2m around the pool. If you wish to entertain around the pool then this size will be considerably bigger to allow for furniture, BBQs and even a pizza oven if you will! If you are simply looking for exercise you could get away with a very small surround around the 3 edges that you do not get out of and have a larger area near the stairs to get in and out of.

Swimming Pool Shape

When looking at the cost of swimming pool installation a major factor is the shape of the pool. If you dream of a circular pool, then the construction costs typically increase from a more conventional rectangle shape as the build becomes more complex. Broadly speaking, the more complex the shape the higher the construction costs will be.

Most UK pool owners opt for a conventional rectangle shaped pool. You may also consider adding a roman end step to your pool which gives it a more classic look. A roman step is a semicircle of steps that are typically sited at the shallow end of the pool which allow a larger step to enter the pool but also to lounge on.

One consideration you need to make before committing to a pool shape is the type of swimming pool cover you wish to have on your pool. A floating solar cover will fit most pool shapes however the reel the cover sits on can be unsightly to some as it sits at one end of the pool when not in use. A safety cover runs on tracks which require straight lines and therefore not ideal for curved pools. A safety cover can allow for a roman end but the tracks need to be inset in or on the coping stones to operate. The final option is a slatted cover. A slatted cover works best with a rectangle pool either with or without a roman end however you can in some cases have a shaped pool work with a slatted cover by using a pit in the floor of the pool which the cover comes out from, the cost of this however can be prohibitive for some.

Swimming Pool Features

The cost of swimming pool installation can vary wildly when you start look at the range of accessories and features you can add to your basic pool design. From fountains, premium fittings, and lighting. Each of these come with an additional price tag. Some features may well be ‘nice to haves’ whilst some should be considered essential. For example a swimming pool cover is a vital piece of equipment to keep your pool efficient and to stop debris from getting into the pool.

Items that are considered essential should always be looked at as a priority as many are not possible to retro-fit after you pool has been installed. Lighting is a good example here, where installing a new light will involve draining the pool. upsetting the finish, cutting a hole, digging up the surround and digging a trench back to your plant room. Not very favourable! Consider your options available and always try to buy the best you can afford.

The Different Pool Construction Methods

There are three main types of swimming pool construction methods, all come with their own positive and negative attributes. Choosing the right pool for you will depend on a number of factors including:

  • Time to install
  • Longevity of the finish
  • Heat retention properties
  • Quality of finish
  • Design & Size
  • Ease of maintenance

Not all pools are created equal. The cost of swimming pool installation for each method can vary wildly, it is always best to understand the pros and cons of each before committing to one particular method.

The three main construction methods are:

  1. Lined Pools
  2. Concrete Pools
  3. One-Piece Pools

Lined Pool Installation

A lined pool is typically constructed from prefabricated panels which create the swimming pool structure. The floor is made by a concrete mix called screed. The space behind the panels is then insulated and backfilled to create the pool shell. Then a PVC liner, either manufactured off-site or on-site is installed to create the final finish. The biggest benefit to lined pools is that the cost is relatively low to install however a swimming pool liner will typically last between 10- 20 years, at this point, liners can become wrinkled and stretched over time, as well as faded in colour, so a replacement is required. The PVC liner is also susceptible to tearing from sharp objects so caution should always be taken when using the pool that sharp objects are nowhere near the pool.

PVC Liners come in a wide range of patterns and colours so finding one you like should be no trouble. If you want a natural look then you may want to opt for a 3D liner which has a texture added to give the effect of natural stone.

Concrete Pool Installation

Concrete pools as the name suggests are constructed using concrete. This can be done in a number of ways:

  1. Reinforced concrete brickwork
  2. Shuttered and poured reinforced concrete
  3. Spayed reinforced concrete (also known as Gunite pools or Shotcrete pools)

The method depends on the size and shape of the pool as well as the budget you have. All methods will create a strong study shell which tiles such as mosaics or large format tiles (like slate or porcelain) are adhered to the shell after a waterproof render is added.

The biggest benefit to having a concrete pool installed over other installation methods is the ability to have any shape or size pool (within the limits of physics) as well as a near unlimited choice of finishes available to you. This method gives you a truly bespoke pool that is totally unique.

One-Piece Pool Installation

One-piece pools are a preformed shell manufactured off-site and then transported to your home and then hoisted into a pre-dug hole. One-piece pools are typically constructed using fibreglass pools or some composite using fibreglass. They are incredibly strong and durable against damage and very easy to keep clean as there are no grout lines or porous surfaces which bacteria and algae can attach to.

One-piece pools are limited to the designs and sizes that the manufacturer produces however there are a wide variety on the market and you will usually be able to find something to suit all purposes. You are also limited to the finishes that the manufacturer produces, again however, there is a large range of colours available and most are totally unique to this style of pool giving you something different than the norm’ of tiles and liner patterns.

Installation of a one-piece pool is very quick and an installation can be as quick as 3 weeks from start to finish (depending on level of finish and surround).

Swimming Pool Covers

A swimming pool cover is an essential piece of equipment for a swimming pool in the UK and can make up to more than 10% of the cost of swimming pool installation. There are different covers available on the market to suit various needs. A pool cover at it’s most basic will retain heat in your pool water making it more efficient. Another benefit to a swimming pool cover is that it will block the sun’s UV rays from burning off the chlorine in your pool which would leave you with a green pool full of algae. Lastly a swimming pool cover protects your pool from debris easily getting into the pool. Leaves and dust will land on the cover which can easily cleared off instead of having to clean the pool using a pool vacuum.

Each of the different types of cover have added benefits which you will be able to see below:

Solar Bubble Cover

A solar bubble cover is the most cost efficient cover available. As the name suggests the solar bubble cover will harness the sun’s rays to help heat the pool. They’re also often referred to as ‘bubble covers’ or ‘pool solar blankets’. A solar bubble cover will float on the surface of the pool and as such needs to be removed before swimming by reeling it onto a swimming pool cover reel. This reel will sit at the end of the pool (typically the deep end). Although some reels come with casters to move them, they are very heavy and cumbersome so many opt to leave them in place while not in use.

Safety Cover

A safety cover as the name suggests will keep you pool locked tight. Children, adults and animals are at risk of serious injury or drowning around a pool if caution is not taken and so safety covers are designed to completely encapsulate the pool to stop anything or anyone entering the pool accidentally. The material used is so strong that you can even walk across it without a problem. The material runs on tracks that can either be hidden in the edge of the pool or installed on the surface behind the coping stones.

An added benefit to a safety cover is that it nearly totally eradicates debris from entering the pool. Pools with safety covers typically will need less maintenance than any other because of this. A great time saver along with the added safety element.

The cover mechanism can easily be mounted in a pit behind the pool so will be virtually invisible once retracted too. The operation is automatic using a pneumatic pump to pull the cover in and out.

Slatted Cover

Slatted covers are probably the most stylish option available to pool owners. The cover can be integrated into your pool or can be built into a pit at the deep end of the pool. Slatted covers are typically automaticly operated and can be opened and closed using a remote control. Slatted covers float on the surface of the water and can hold a decent weight so that animals of people do not fall through and into the pool. Most slats available also have a solar property which can help heat your pool using the sun’s heat.

Swimming Pool Filtration

Every swimming pool requires some form of filtration and sanitisation. For many swimming pools in the UK this can be as simple as a sand filter and a filter pump however there are many upgrades that can be made to increase the efficiency of a swimming pool’s filtration.

A filtration (or plant) room should be watertight so that rain and the elements do not damage the equipment. It should be in easy access from the pool and also ideally on a similar level to the pool. In cases where this is not possible a larger filter pump maybe required to be able to cope. A good control board is required to turn off or on equipment such as pumps and heaters. It is also ideal to have these items with timers.

Each of the different types of sanitation methods have added benefits which you will be able to see below:

UV Sanitation

Working alongside a sand filter, a UV system will disinfect water efficiently and safely by exposing the passing water to high doses of UV light. This stops the growth of mould and bacteria and keeps algae under control. It does not allow you to stop using chlorine however it will help you reduce the amount you use.

Salt Chlorination

An alternative to usual chlorine based sanitation a salt chlorination system will use electrolysis to convert salt into chlorine ions which kill off bacteria and algae. The salt in a swimming pool can be as low as 2,500 parts per million (sea water is approximately 35,000ppm) so you will not taste or feel salt in the water or you skin.

The cover mechanism can easily be mounted in a pit behind the pool so will be virtually invisible once retracted too. The operation is automatic using a pneumatic pump to pull the cover in and out.

Swimming Pool Heating

Heating your swimming pool doesn’t have to be expensive. A heated swimming pool increases enjoyment and lengthens the season, so you can continue to swim even when the conditions outside are a bit cooler. Depending on the type of swimming pool and location we can install solar heating, natural gas, oil, electricity or an air source heat pump. We will advise you on the most suitable method for your pool, and estimate running costs.

Each of the different types of sanitation methods have added benefits which you will be able to see below:

Gas or Oil Pool Boilers

This is the most common way to heat a swimming pool is by use of a gas or oil fired boiler. One of the primary benefits of this method is for heating the pool water quickly however it is not the most cost efficient and at its most efficient when used for a short period of time, rather than maintaining water temperature over a number of days. A Gas or Oil boiler is ideal for pools which aren’t in everyday use. As the pump draws water through the pool filtration system, it then passes through a heat exchanger either within the boiler or connected via coper pipework where the heat generated by burning gas or oil is transferred to the water before it is moved back to the swimming pool.

Air Source Heat Pumps

Heat pumps are gaining in popularity for heating pools, especially as the costs of fossil fuels continue to rise. Heat pumps are powered by electricity. They don’t generate heat themselves, but draw cool air in from outside, pass it over an evaporator coil and through a compressor. Heat is generated within the compressor, which is then transferred to the cooler pool water which is circulating. The ambient air doesn’t itself have to be warm though, clearly the warmer the air, the more heat is available to extract, and the more efficiently the heat pump will operate. Air Source heat pumps are a similar price to your typical dedicated swimming pool gas or oil fired boilers, but due to their higher efficiencies have lower annual operating costs.

Electric Heating

Electric heating directly heats pool water via an array of stainless steel or titanium electric heating elements. With escalating electricity prices it is seen and the least viable of the direct heating systems and tends to only be installed in situations where there really is no other alternative.

An Electric Pool Heater

The cost of heating your pool depends on the size of pool, whether it’s an outdoor or indoor swimming pool, how well insulated it is, what kind of cover you have and the type of heater you choose. It’s impossible to give an accurate daily running cost given the number of variables, but as an example, for a small 12 foot round outdoor pool you might expect to pay between £50 – £200 to heat your pool for a summer swimming season.

Swimming Pool Heating Cost Guide

Based on a 32’x 16′ outdoor pool, covered 20 hours per day, daily use, low water table.

Please note that the running costs are only estimated running costs and therefore should only be used as a guide. They have been based on the following tarrifs:

  • Electric: 0.12 £/kWhr
  • Gas: 0.044 £/kWhr (boiler efficency 90%)
  • Oil: 0.0584 £/kWhr (60p per litre) boiler efficiency 85%

Swimming Pool Surrounds

The exterior of your pool is made up of coping stones, i.e. the paving blocks that immediately surround the pool, and other surrounds such as block paving or decking. We provide a comprehensive range of options that can enhance the overall cosmetic appeal of your swimming pool. Choose a pool surround that maximizes safety while adding a stylish finish to your swimming pool. There are a variety of non-slip surrounds available, in different colours and styles depending on your taste.

Tiles and Paving

There are many options to go for here, and your choice could completely change the look and feel of the pool. Smooth or textured, straight or curved, black or white… Here’s where you can get creative and design your pool surround to provide something safe and functional, or invest in a patio or seating area to maximise your enjoyment of the pool. When you’re making your choice, consider how much upkeep your tiles will need to remain looking good – how susceptible they are to fading, and whether they need to be regularly jet-washed.


It’s important to have coping tiles or slabs around the immediate edge of your pool, to protect the pool and its users. If you’re looking for a softer aesthetic look for the rest of the pool surround though, decking could be a good option for you. It will need to be reinforced with concrete slabs, and it’s important to choose decking that will not crack or splinter, especially if you consider that people will be walking around the pool with bare feet.

Swimming Pool Enclosures

If you have ever thought about owning an indoor pool but the cost of swimming pool installation indoors is cost prohibitive then a swimming pool enclosure could be for you. A pool enclosure will allow you to use your pool all year round, day or night, raining, snowing, windy, cold or dark.

The climate in the UK is always a little unpredictable and therefore can be frustrating for pool owners who plan to take a swim but find the weather denies them the opportunity. A swimming pool enclosure will extend your pool’s usage so you can use it all year round. Not only the obvious benefits, it will also make your pool safer by locking the pool area up when not in use, stopping young children from climbing in without supervision.

Covering a pool is a great way to save on the usage of chemicals, using an enclosure will further help this which substantially reduces the amount you would have to spend on an annual basis. Don’t forget an enclosure will also protect the pool from the debris entering the pool so you would spend less time cleaning your pool and more time enjoying it!

Pool Enclosures do not have to be full height for you to walk around. They can be made to be low level so you can get in and swim in the pool and enjoy all the benefits of an enclosure without a large structure in the garden.

The enclosures XL Pools provides can also be made to fold up at both or one end opening the pool up to the world when the weather is nicer.

The Cost of Swimming Pool Installation for Indoor Pools

The cost of an installing an indoor swimming pool as we have mentioned before will vary depending on the size, shape and construction method. Naturally with and indoor pool you will need a building to also house the pool in. It is sometime possible to install a swimming pool in an existing building however this can become expensive as the walls will need underpinning especilly if the pool is close to any supporting wall.

Indoor pools require some different equipment than outdoor pools. Specifically you will need some form of envionmental control which controls the humidity and heat of the air in the pool hall. Costs for a dehumidfication system start at around £5,000 for a simple wall hung unit to a £25,000+ for an advanced ducted system.

A basic swimming pool of an average size will typically cost between £50,000 – £100,000. With the additional equipment needed for indoor use, you should expect a total installation cost of £70,000 – £130,000. Then you need to consider the cost of the building which will be with a professional builder to cost.

The Cost of Swimming Pool Installation for Outdoor Pools

The cost of an installing an outdoor swimming pool will also vary depending on the size, shape and construction method. There maybe some additional landscaping cost required to level and clear the area where the pool is to be sited. Other additional costs could include re-location or removal of the soil dug out for the pool.

Including the typical options added to a pool and of a regular sized pool for the UK, your outdoor swimming pool could start at £50,000 and work upwards to £80,000. With some addional extras this could be pushed up to £100,000 if you decided on a nicer tile or wanted a slatted cover.
