Steel wall pool in the ground

Updated: October 2026

A bullet that says the shell can sit in the ground is not planning permission. For this set, two amazon.co.uk listings mention a recess and three say nothing. The shells are the five on the [steel wall pool comparison](/hub/swimming-pools/steel-wall-pool), taken on 16 October 2026. There was no excavation and no laboratory test. A qualifying purchase can earn a commission at no extra cost to you. England’s Class E limits are below. Wales, Scotland and Northern Ireland use their own orders. A free-standing base stays on the [how to set up a steel wall pool](/hub/swimming-pools/steel-wall-pool/sub/steel-wall-pool-how-to-set-up) page.

Which shells mention a recess

Only two listings say the shell can be recessed. The Summer Fun round, B07QB4YGCG, at £1,025.53, says it can stand free, sit partly in the ground, or sit fully in the ground. It does not describe the hole, the backfill or a diameter in metres. The Planet Pool oval, B09Q3NFKCM, at £1,936.75, says it can be partly recessed or recessed. Title and attributes agree on 600 × 320 × 150 cm. The box includes a grounding set. Weight and capacity are not stated. The other three are silent. The Grandy, B07Q7XN14K, recommends a concrete base plate, which is a slab, not a recess. The 90 cm rounds B0DPZFNDDD and B09QT25X6Z do not mention the ground. Silence is not a hidden yes. The top pick among the two that do speak is on the best steel wall pool page.

England Class E

In England, a swimming pool can be permitted development in the curtilage under Class E of the General Permitted Development Order 2015. The Planning Portal says an outdoor pool is often permitted development when the outbuilding limits are met, and it still tells you to ask the council. Class E fails in front of the principal elevation, if buildings and pools cover more than 50 per cent of the curtilage, in the curtilage of a listed building, and where pools more than 20 metres from the house would exceed 10 square metres. Article 2(3) land has a further limit beside a side wall. A product bullet cannot repair a Class E failure. Ask the council before you hire a digger.

The rest of the UK, and building control

Wales, Scotland and Northern Ireland do not use England’s Class E wording. Start at mygov.scot or GOV.WALES for those nations. Building regulations are separate from planning. The Planning Portal says building regulations approval is not normally required for an unenclosed outdoor pool, and that an enclosure changes the question. None of these listings describes an enclosure. The steel wall pool buying guide still comes first: a recess claim on a listing whose sizes disagree is not a hole you can set out.

Backfill, the grounding set, and a barrier

These bullets do not specify backfill or a dig depth. Call a builder if the ground is soft or the hole would sit beside a footing. The large oval packs a grounding set and states no voltage, so call an electrician under Part P and BS 7671:2018. A barrier is still the layer around the water after planning is settled. SPATA says there is no domestic statute that forces a fence, and it still treats a barrier as a layer. RoSPA wants supervision and a self-locking barrier. RLSS UK publishes fencing of at least 4 feet for a residential pool. NetRegs flags a note once a pool and its auto-refill sit over 10,000 litres. Two shells print a capacity above that line, 11,000 litres and 13,500 litres. The other three print no capacity. These listings do not make a BS EN 16582 claim.

Common questions

Does that bullet mean you may dig?
No. It means the listing claims the shell can be installed that way. It does not describe the hole, and it is not a decision under the General Permitted Development Order. In England, Class E can allow a pool and still fail in front of the house, on a listed curtilage, over half the garden, or past the 10 square metre limit far from the house. Ask the council before you dig. A warranty bullet does not replace that ask.
Do the same rules apply in Wales, Scotland and Northern Ireland?
No. Each nation has its own permitted-development order. England’s Class E is the text cited here. For a house in Scotland start at mygov.scot, and for Wales at GOV.WALES. Do not carry an English often-permitted sentence into Cardiff or Glasgow and treat it as consent. Ask the council that would actually decide, or confirm that an application is not needed.
Does an outdoor pool need building regulations approval?
The Planning Portal says approval is not normally required when the pool is unenclosed, and that an enclosure changes the question. These listings do not describe a housing, a deck or a plant room. Planning and building control are different desks. A pool that is permitted development can still need a builder for soft ground, and an electrician for a fixed pump or for the grounding set.
What extra work comes with the grounding set?
The box for B09Q3NFKCM includes a grounding set and states no voltage, capacity or weight. Connecting that set, and any fixed pump you add later, is electrical work. Part P and BS 7671:2018 are why you use an electrician rather than an extension lead. The recess bullet still does not say how deep to dig. The electrician does not replace the council, and the council does not bond the steel.
