Answers to your frequently asked questions

Here are some frequently asked questions that we think will help you when planning your pool project with Cascade Pools.
If there are any other questions or you would like further information on our swimming pools, accessories and the advantages of having a Cascade Pools pool, please feel free to contact us, we are always happy to help.

Do I need planning permission?

Pools situated outdoors or those in a detached house that will be privately used, will not need to have planning permission, unless there may be disturbance to buildings or drains. You may also need planning permission if your home is a listed building, situated in an area of outstanding beauty, green belt or had the permitted development rights removed. If in doubt call your local council planning department for an informal chat, they should be able to help you.

However, for indoor pools, Building Regulations consent will be required. It could also be an idea to bring in an architect to draw up basic drawings and measurements for your new build. If you are ever in doubt, contact us for advice or contact your local authorities.

How much would it cost?

A basic liner swimming pool installation can range from £16,895 for a 10' x 20' pool up to £30,650 for a 20' x 40' pool. These prices exclude off-site soil disposal, electrical supply and connections, heaters, covers, rollers and pool enclosures. Optional accessories are also available as well as landscaping and paved surrounds. If you have any queries we are happy to take your call and help you with any pricing costs.

What is the difference between liner and concrete swimming pools?

Liner swimming pools are made up of a framework or shell constructed of various materials available, including; galvanised steel or polymer panel s. It is then lined with a PVC membrane (called the liner) which gives the pool its water retaining properties. The liner pool with its many different colours and patterns including mock tiling or mosaic with its high standard of construction and finish is a cost effective method of owning an installed pool and many people cannot tell the difference between a liner and tiled pool!

Whereas a concrete swimming pool, using the traditional way to construct a pool, can be divided into four different categories; reinforced blockwork, unreinforced blockwork, sprayed concrete and shuttered concrete. Instead of fitting the swimming pool with a frame the swimming pool has a concrete and sand shell, which is ready to be tiled over and made waterproof.

What are the advantages of a panel & liner pool?

Having a panel and liner swimming pool can be incredibly advantageous for people who like to have a bit of leisure in their lives. When your swimming pool is installed with a liner, it becomes virtually maintenance free and you can also choose across a variety of colours and patterns for your liner.

We at Cascade Pools have been installing panel and liner pools for over 40yrs and believe they are well suited to the heavy clay ground conditions in this area offering a degree of flexibility within the structure against any potential ground movement damage to the pool shell unlike concrete tiled pools which could crack under certain diverse weather conditions and cause a real problem for the owner.

What size pool should I get and what would be the capacity of my pool?

To get an idea for the size of pool that will suit your garden and requirements, it is advised to chalk the outline and measure, it will also give you a visual idea. However, bear in mind that you will need to allow space for the paving that goes around the perimeter of the pool. To get a rough idea of what size pool you would like, the average family sized outdoor swimming pool is around 10m x 5m (approx 32 feet x 16 feet) and an indoor pool is approx. 8m x 4m (28 feet x 14 feet).

It is very important to know the capacity of your swimming pool to enable the correct water balance to be maintained by adding the correct quantities of chemicals required to the water.
Below is a quick formula to help you find out:

• For circular pools:

Imperial : Diameter (ft) x Diameter (ft) x Average Depth (ft) x 4.9 = Gallons

Metric: Diameter (m) x Diameter (m) x Average Depth (m) x 0.8 = Cubic Metres.

• For rectangle or square pools:

Imperial : Length(ft) x Width (ft) x Average Depth (ft) x 6.25 = Gallons

Metric: Length (m) x Width (m) x Average Depth (m) = Cubic Metres.

• For oval pools:

Imperial : Long Diameter (ft) x Short Diameter (ft) x Average Depth (ft) x 5 = Gallons

Metric: Long Diameter (m) x Short Diameter (m) x Average Depth (m) x 0.9 = Cubic Metres.

What help and technical information will I receive throughout the project?

When you start your pool project with Cascade we ensure you and all workers share the same information, so you are never left in the dark. All relevant information regarding the different aspects of the pool installation is available to the customer initially and throughout the installation.

What types of heating are available to me?

Swimming pools can be heated by a selection of energy resources including gas, electricity, oil, ground and air source heat pumps, solar, wood pellet burners and even wind turbines. However, renewable energy is only suitable for outdoor pools, as indoor pools require dehumidification and a sophisticated range of systems.

One of the most popular heating systems for swimming pools is the heat pump, as it is effective and economical (should cost approx. £2.00 per day to heat depending on the size of the pool).

We recommend you take advice from a suitably qualified electrician or heating engineer for technical questions relating to your existing household electrical supply or capacity of existing gas or oil boilers to enable us to assess if your current services are sufficient to support your preferred heating choice for the pool.

Should I cover my swimming pool?

Yes! There are many purposes of a swimming pool cover, it can keep the pool safe, clean, warm, control the humidity of an indoor pool, and act like a solar blanket for outdoor pools. Particular covers can also be used to help with the safety of the swimming pool for instance, preventing children accidently falling into the pool. There are also a variety of pool covers available including manual, semi-automatic and automatic systems.

If you have an irregular shaped swimming pool it is important to find a cover that can be custom fit to the shape of your pool.

How long will it take to build?

A liner pool can take on average 3-4 weeks to install. However, paving and other extras can prolong the completion of the build. The length of time it takes for a pool to be completed usually depends on a range of variables such as, weather conditions, ground conditions, size of pool being installed and sometimes suppliers. The accessories; depending on the accessories you have chosen for your swimming pool or the amount of accessories you want installed can also alter the original time frame given. For a more accurate quote please contact us with your enquiry and we will be more than happy to have a chat about your requirements.

What kinds of steps are available?

Having steps or ladders incorporated into the build is an essential to your everyday swimming needs as they allow fast and easy access out of the pool without running the risk of hurting yourself when trying to lift yourself out of the pool. They are also essential for the health and safety of the pool.

There are a wide variety of steps to choose from including; stainless steel ladders which drop in over the side of the pool or Walk-In Stairways, including square, roman (half moon) or corners. For indoor pools internal corner or roman steps are ideal as it won't take up any room around the pool. With outdoor pools you have more choice with the design and style of the steps.

How long should the liner last?

It is predicted that a liner should last for approx. 7 to 10 years; however there are liners that are more robust and can last for about 10 to 20 years. There are different grades of liners, with different life expectancies, for example the standard 20thou (0.5mm) and 30thou (0.75mm) liners carry a 5yr pro rata warranty but usually last for around 10 years, whereas the much thicker 60thou (1.50mm) liner has a pro rata warranty of 10 and could last for around 20yrs. (this all depends on the after care of the liner by the customer)

To guarantee a longer life for all pool liners, it is recommended to keep the swimming pool well maintained using the correct pool chemicals and keeping the water temperature within the recommended limits

Are there any extras available to me?

Yes! If you require lighting for your swimming pool there are many options to consider including underwater lights, colour changing LED lights or fibre optic lighting. You can also consider having chlorine free systems fitted, automatic water top up systems, counter current units or swimjets and much more. Heaters, covers, rollers, enclosures and additional paving surround are also available plus just about everything else that you may need to make your swimming days complete. For more information about accessories and other extras please contact us, we are more than happy to help.

What is the best way to protect my pool?

The most effective and simple way to help protect your pool is with the use of a cover. There are many kinds of covers available for all purposes from keeping the pool safe and clean to keeping your swimming pool warm by acting like a solar blanket for an outdoor pool or controlling the humidity for an indoor pool. It is always a good idea to protect your swimming pool, especially in the winter months to reduce any problems with your swimming pool, such as cloudy water and green staining.

What is the most effective way to clean my pool?

This all depends on the systems you have fitted in your pool. However, there are many automated cleaning systems that are available to you, to help minimise the time and effort required when keeping with the maintenance of your pool. There are suction cleaners, sweeping cleaners and electrical self-contained cleaners. If you require any information about the cleaning systems available please contact us.

Can I heat my pool in an eco-friendly way?

Swimming pools can be heated by a selection of energy resources including ground and air source heat pumps, wood pellet burners, solar and wind turbines. However, renewable energy is only suitable for outdoor pools, as indoor pools require dehumidification and more sophisticated systems. The most effective and cost efficient to heat a swimming pool is by heat pump.

Pool insulation is another way of maintaining the heat within the pool and has the potential savings of up to 90% of the running costs when operational. New build pools can have the insulation incorporated at the build stage or existing liner or concrete/tiled pool shells can be insulated when the pool is being refurbished.
