Cost guide
How much does a natural swimming pond cost?
A bespoke, high-craft project, priced individually after a site visit. Here is what shapes it.
In short
A natural swimming pond is a significant, bespoke project, and there is no single price that means anything in advance: the cost is driven by the size, the construction method, the filtration and the site. Rather than quote a figure blind, we look at your garden and what you want from it, then set out a clear, honest proposal. What we can say is what shapes the cost, and where the value lies.

What you can expect to pay
Figures are relative, not quotations. Each scheme is priced after a survey.
| Why | What shapes the cost |
|---|---|
| The single biggest factor | Size, and the swim-to-regeneration-zone balance |
| A quality liner system versus a concrete build | Construction method |
| The system that keeps the water clear | Filtration and circulation |
| Excavation and getting plant in | Site and access |
| The regeneration zone that does the work | Planting and establishment |

What changes the price
The factors that move the figure
A natural swimming pond is not a liner dropped into a hole. It is a balanced, living system: a swim zone for you and a separate regeneration zone of planting and filtration that keeps the water clean and clear without chemicals. That engineering, and the excavation behind it, is where the cost sits. The big variables are size, the construction method, the filtration, and the site itself, particularly access for machinery and the ground you are digging into. A compact pond on an open site is a very different job from an estate-scale scheme with a formal finish. It is worth weighing the runnin

It is a major excavation and construction project with a balanced biological system, not a liner in a hole. The regeneration zone, filtration and planting all have to work together, and that engineering is where the cost sits.
The build is comparable to a quality pool, but the running costs are far lower, with no chemicals and less mechanical plant, so the saving comes over the years rather than on day one.
Yes. Converting a conventional pool to a natural pond is increasingly popular and can make good use of the existing structure. We assess it on site.
