Building a swimming pool FAQ’s

Q: What are the key design considerations when choosing a pool? A: As an energy efficiency award-winning company, we believe that energy efficiency is one of the largest factors to consider when designing your pool, you want a pool that will be durable, wonderful to use but one that does not require extensive running costs. For indoor pools, de-humidification rates, airflow, and heating need to be specified individually to offer a flexible yet energy-efficient system. As with all designs, your lifestyle should play a key part in designing your pool, how do you plan on using your pool, predominately recreational or for training. There are a plethora of options to create a perfectly bespoke pool including sound systems, lights, massage stations, water fountains and swim jets. Blue Cube Pool loves to work with customers to create a unique and lasting pool for you and your loved ones. We will look at all key factors including postponing of pipes, air ducts, maintenance access, ease of use and functionality.

Q: Do I need planning permission for a swimming ground pool? A: When building a domestic outdoor private swimming pool most authorities in the U.K do not require planning permission, however it is always worth checking especially if you live in a conservation area, the property is a listed building, your pool will take up over 50% of the garden or your pool is overlooked by a public highway or path. Permission will be required if you are erecting an enclosure or specific pool room. Even though planning permission may not normally be required Blue Cube Pools recommend that you contact your local authority before commencement of any work in order to check the requirements of local legislation.

Q: Common problems with a pool installation? A: Most common pool installation issues arise due to the company you choose, with this in mind we suggest using a verified and industry associated company. SPATA is the swimming pool governing body that ensures pool companies follow strict regulations. Read reviews of the company you are investigating and if needs be ask for proof from previous customers. Unfortunately, there can be delays during pool builds, these are usually caused by the weather, so always bear in mind that an outdoor pool will need to be built during the warmer months as the cold will impact on tiling, liner installations, and other aspects. Always choose trusted equipment brands but any good pool company will already choose these.

Q: Can I build a pool myself? A: Yes, you can – There are various DIY pool kits available from wooden pools, to block and liner kits. Our pool kits are designed to be easy to use and can be adapted to suit your design ideas.  However, many customers use a local tradesman for rendering and tiling. Blue Cube Pools are here to help every step of the way during your pool build. View our DIY pool kits.

Q: Should I buy a DIY kit or have the pool installed? A: This depends entirely on what you feel comfortable with. It is possible to buy a DIY kit and then hire tradesmen to do certain aspects, however you need to ensure that the tradesmen work together, and the project is planned correctly. As previously mentioned, there are various types of DIY pools and they all have their advantages and disadvantages. Talk to one of our team to find out more.

Q: What about my water rates? A: Apart from the initial filling of your pool it will require very little water apart from the occasional top-up due to evaporation and vac to waste. Using a cover will reduce evaporation

Q: What size pool do I need? A: The size of the pool you choose often depends on the space you have and your budget. However, it is not always necessary to invest in a large pool as there are amazing swim jets and counter-current systems that allow you to swim in one spot. The average pool size is 10m x 5m (30′ x 15′). Certain environmental factors can impact the size of your pool including underground cables, overhead wires, ground structure, and the water table. You will also need to consider access for heavy machinery.

Q: Why choose a liner pool? A: Yes a tiled pool looks beautiful, but they will always be expensive than a liner. With the new advances in liner production in design and durability, they can offer very similar visual effects to tiles and in some cases, it is almost impossible to tell the difference until you are in the pool or look closely. Liners can last up to 10 years when well looked after and are easier to replace and are less expensive.

Q: What are the associated swimming pool running costs? A: Swimming pool running costs are dependent on a number of factors such as the size of the pool, the type of heating, choice of cover, these can all impact on energy bills. The following items should be considered when calculating monthly or yearly costs: Chemicals, Maintenance, Electricity and Heat Source.

Q: Do I need a cover for my pool? A: Yes, pool covers will aid in reducing heat loss and evaporation which will help you cut your running costs. Covers are even more crucial for indoor pools as evaporation can cause issues with the surrounding environment.

Q: What is the best way to heat a pool? A: There are four main ways to heat a pool, electric, solar, gas, and oil. Unfortunately, due to the UK weather solar is not always the best option and can be costly, it can be used as a secondary source of heat as we do get some amazingly hot days. Oil and gas boilers work in very similar ways and are usually used by people who do not have an electric supply or they wish to incorporate their pool heating with their home heating system. However, we have found the most cost-effective and eco-friendly method is to use a heat pump. They offer unbeatable COP and therefore have a great return on investment. To find out more about heating options read our blog here. For greater energy efficiency insulation is key which is why we recommend an insulated cover and thermal polyblocks for our new builds.

Chemical FAQ’s

Q: Does chlorine prevent all waterborne illnesses? A: A well maintained and dosed swimming pool will prevent waterborne illnesses which can cause illness in its users. Chlorine kills germs and bacteria however we recommend shocking your pool occasionally to prevent bacteria such as giardiasis from developing. Outside factors such as sunlight, debris, and body oils from swimmers can all affect bacteria levels which is why it is recommended that swimmers shower before use

Q: When do I need to shock my pool? A: As previously mentioned, it is sometimes necessary to shock your pool, this should be done routinely to destroy water contaminants such as hair spray, sun cream and organic materials which can reduce the effectiveness of your sanitiser. These contaminants can react with chlorine and cause unwanted reactions such as eye and skin irritation.

Q: What causes Chlorine odour, red eyes, and itchy skin? A: Your pool water smells strongly of chlorine, your eyes are red, and your skin is itchy, this is not a sign that you have too much chlorine, it is an indication that your pool needs additional chemical treatment. This smell is due to high levels of chloramine, these are formed when chlorine molecules combine with contaminants such as body oils, urine, and perspiration. In this situation, we would recommend testing your pool and potentially adding a shock treatment. For further advice contact one of our expert advisers

Q: How long do I have to wait to use my swimming pool after chemical treatment? A: Generally, it is safe to use your pool after chemicals have dispersed throughout the pool, usually 15 minutes to one hour. If shocking your pool, wait until the chlorine levels drops to recommended levels.

Q: How often do I need to test my pool water? A: Weekly testing is advisable for most pools, but testing depends on the level of activity in your pool and the season. We would suggest testing your pool pH and chlorine levels at least twice per week especially during busy periods to ensure the safety of your swimmers. Chlorine should be fed continuously through a chemical feeding device to maintain levels. If you have an automatic dosing system, it is still advisable to regularly test your pool manually to make sure your system is functioning correctly, and levels are accurate.  

Q: Is there an alternative to using chlorine? A: Although chlorine is the most commonly used santiser there are others on the market for those who do not like the smell or find that it irritates their skin. Active H20 and bromine are great alternatives. For advice on what will suit you and your pool contact us today.

Q: What type of chlorine should I use? A: Chlorine is available in many forms and types but for domestic use, either granular or tablet forms are most commonly used. Many people opt for tablets as they are easy to use in a dispenser, simply place your tablet in your dispenser and place it in the pool, the tablet will slowly dissolve and provide a constant dose of chlorine. Should you use granular chlorine make sure to pre-dissolve it before adding it to the pool so that it can fully circulate throughout your pool water.

General FAQ’s

Q: How can I keep my pets and children safe around our pool? A: Safety should be a key feature that every pool owner considers, even if you do not have children or pets you will be amazed by the creatures that turn up in your pool. Each year we see various animals and birds who have a mishap. We always suggest our customers invest in an automatic safety pool cover where possible. They come in various styles and colours and they often look aesthetically pleasing.  Keep children away from pool drains, pipes, and other openings to avoid entrapment. If you have an older pool and have any concerns about your equipment and its safety, please contact our team. Use correct safety and buoyancy equipment, watch children at all times.
