Borehole planning permission and abstraction licensing

Borehole planning permission is usually needed not for the hole but for everything around it. The shaft itself is often treated as an engineering operation of no visual consequence, while the kiosk, the chamber lid above ground level, the pump housing, the security fencing and the access track are plainly development and need permission unless a specific class applies. Running in parallel is a separate regime: abstraction from a borehole above 20 cubic metres a day needs a licence from the Environment Agency under the Water Resources Act 1991, and that licence has nothing to do with the local planning authority.

Whether the borehole itself is development

Drilling a borehole is an engineering operation, which falls within the definition of development in section 55 of the Town and Country Planning Act 1990. Authorities take different views on whether a flush-finished borehole in a field amounts to development requiring permission, and several treat a small investigation or supply borehole with no structures above ground as not materially affecting the land.

Do not rely on a general view. Ask the authority in writing, describe the headworks accurately, and if the answer matters commercially, apply for a certificate of lawfulness for the proposed use or development under section 192 of the 1990 Act.

On an agricultural unit, Part 6 of the General Permitted Development Order 2015 permits certain buildings and engineering operations reasonably necessary for agriculture, subject to area and size limits and, for some development, a prior notification to the authority about siting, design and external appearance. A farm supply borehole with a small kiosk often fits. A borehole for a commercial bottling operation does not, because the purpose is not agriculture.

Headworks, kiosks and the structures above ground

What the authority is actually assessing is a small structure in a field or a yard, so the planning case is short and visual. Submit a site plan with the borehole and the headworks positioned, elevations of the kiosk with dimensions and materials, details of the fencing, and the access arrangement.

Three points usually come up. The kiosk colour and finish, where a dark recessive finish in a rural setting avoids an argument. The security fencing, where palisade reads as industrial and a post-and-wire enclosure with a lockable hatch usually does not. And lighting, which is best omitted entirely unless there is an operational need.

A Planning Statement for this kind of application is short and should deal with the need for the supply, the alternatives considered, and the visual and landscape effect. If the borehole supports a wider development, say so and cross-refer to the main application.

Abstraction licensing and the volume thresholds

Abstraction of water from a borehole requires an abstraction licence from the Environment Agency where the quantity exceeds 20 cubic metres a day. Below that figure, no licence is needed, which is why domestic and small agricultural supplies often proceed without one.

Licences come in forms: a full licence for ongoing abstraction, a temporary licence for a short period, and a transfer licence for moving water between sources. The Agency assesses the effect on the water body, on other abstractors and on protected sites, and in catchments where water is already fully committed it will refuse or restrict. A licence can also carry hands-off flow or hands-off level conditions, under which abstraction must stop when the river flow or groundwater level falls below a stated value.

There is a separate statutory notification. Section 199 of the Water Resources Act 1991 requires notice to be given of the construction of a well or borehole deeper than 15 metres sunk for searching for or extracting water, and the records that follow are what makes the national borehole archive useful to the next person on the site.

Check the licensing position before the planning application, not after. A permission for headworks serving an abstraction that cannot be licensed is worth nothing, and the Agency's view on availability is the controlling constraint on most schemes.

Source protection zones and contamination risk

The Environment Agency maps source protection zones around public water supply abstractions, with an inner zone based on a 50 day travel time to the source, an outer zone based on 400 days, and a total catchment zone. Its groundwater protection position statements set out what it will and will not accept in each.

Two consequences follow. If your borehole is inside someone else's source protection zone, the Agency will scrutinise anything that creates a pathway to the aquifer, and a poorly sealed borehole is exactly that. If your borehole creates a new source protection zone, activities on neighbouring land become constrained, which can be a material consideration on other applications and occasionally a commercial problem for the neighbour.

Where the site has an industrial history, the risk runs the other way: drilling can connect contaminated made ground to a clean aquifer. The investigation should establish the ground conditions and the contamination status first, and where there is a reasonable possibility of contamination the authority will expect that work to be done to the relevant standard by a suitably qualified person.

Specify the borehole construction to deal with it: a grouted annulus through the made ground, a sealed surface completion above the surrounding level, and a headworks chamber that cannot pond water around the casing.

Access tracks, pipelines and the route

The part of these schemes that generates objections is rarely the borehole. It is the track.

A new access track across a field is development, and in a National Landscape, a National Park or open countryside it is often the main landscape issue. Use an existing farm access where one exists, specify a bound or reinforced grass surface rather than tarmac where loadings allow, and show the drainage of the track itself, because a track that sheds water onto a lane creates a highway problem.

The pipeline route raises the question of rights rather than planning. A buried pipe below ground, where it does not materially affect the land, may not need permission, but it does need an easement where it crosses someone else's land. Deal with that before the application rather than discovering it at the point of construction.

Where the borehole serves a new development, pull all of this into a Water Supply Assessment that states the demand, the source, the licensing route and the fallback if the licence is refused. The wider connection picture sits in a Utilities Assessment.

Monitoring, metering and the conditions

Expect conditions on both sides. The abstraction licence will usually require metering, record keeping and returns to the Agency, and may require monitoring of groundwater levels in observation boreholes. The planning permission will typically condition materials, landscaping, the access surface and sometimes the removal of the headworks if the abstraction ceases.

Offer the restoration condition yourself. A commitment to decommission the borehole properly and remove the kiosk if the use stops costs little to give and removes the authority's main long-term concern.

What to submit alongside the licence application

The Agency's application needs the abstraction quantities, the proposed use, details of the source and the borehole construction, and an assessment of the effect on the environment and on other abstractors. Pumping test data is the evidence that carries it, which means a test borehole and a programme of testing before the full application.

Sequence the work in this order: desk study of the hydrogeology and the licensing position, test borehole with pumping tests, planning application for the headworks and access, abstraction licence application, then construction. Reversing any two of those steps is how money gets wasted. River and bank works have a similar web of consents, as our note on getting permission for a pontoon or slipway shows.

This is general guidance, not legal advice. Check the position with your local planning authority, the Environment Agency or a qualified professional before relying on it.
