These notes are for guidance only, and relate to the installation of a domestic pool in general terms. An experienced pool specifier should be commissioned to oversee drawings, design the circulation and filtration system, to advise on heating and treatment systems and specify equipment. Onsite inspections and project management will also be needed. For this service please contact Compass Pools. You can download a PDF version of this guide here.

Planning Consent for Swimming Pools

Statutory Instrument No 418 of 1995 The Town and Country Planning General Development Order 1995, Page 30 Class E of Part 1 of Schedule 2 permitted development. This indicates that planning permission is not required for an outdoor swimming pool. However it will be required if it is in: –

  • Listed building.
  • National park.
  • Area of outstanding beauty.
  • Conservation area.
  • Area as in Wildlife and Countryside act 1981.
  • In front of building or 20 m of a highway of any sort or usage

For an indoor swimming pool Building Regulations approval must be sought regarding Part L – insulation of the pool shell. In general terms it is better to contact the local Planning Dept and ask, they are always happy to advise.

SOME BASIC QUESTIONS

Before the designer can start there is some information which is essential and, generally, can only come from the end user.

What is the pool to be used for?

  • Swimming up and down for exercise?
  • Diving from the side or off a low board?
  • Aerobics?
  • Wallowing?
  • Recreation?

All these will have an impact on the shape and size of the pool.

Where is it to be sited?

When deciding on the site of an outdoor pool, facing south to maximise exposure to the sun is usually the best option. However take into consideration shadows and the time of day the pool is to be used. Many people think that trees are a nuisance. Perhaps they are, but a completely tree free site is almost impossible to find except in the middle of the desert, and trees also provide a natural protection of privacy and shade. Most outdoor pools tend only to be open from Spring, through Summer and into early autumn and, as such, are closed and covered for the main part of autumn and into winter. If a client wishes to use the pool for a greater part of the year, thought must be given to siting it in relation to trees to minimise falling leaves getting into the water. An indoor pool, contrary to popular belief, does not have to be in the middle of its designated pool room.

What is the size and shape?

This will mainly be decided by the usage. Remember that the bigger the pool the greater the running costs; the wider the pool the greater the cost of spanning it; the deeper the pool the greater the volume of water that is rarely swum in.

What fuel services are available on site?

This affects the choice of heating equipment. See section on heating.

What temperature is required?

In general terms, the greater the temperature, the higher the running costs, which is logically to be expected. However, it is important to understand that as water temperature increases, the energy consumption – and therefore the cost – of doing so increases exponentially. In simple terms, disproportionately more energy will be consumed raising the pool from 25C to 30C and maintaining it there than from 20C to 25C, even though the intervals between the two – i.e. 5o C – are the same.

This is because as the water temper
