What is a consultee in a planning application? Statutory consultees explained

A consultee is a body or person the local planning authority asks for a view on your planning application before it makes a decision. Some are named in law and must be consulted on particular kinds of development. These are the statutory consultees, such as the Environment Agency on flood risk and the Lead Local Flood Authority on surface water drainage. Others are consulted simply because there is a planning reason to hear from them. The point to hold onto from the start is that a consultee advises; it does not decide. The decision stays with the council, or on appeal with the Planning Inspectorate.

For flood and drainage schemes this matters more than for almost any other type of application. The two consultees that most often shape the outcome, the Environment Agency and the Lead Local Flood Authority, both live in this space. Understanding who is consulted, when, and with what weight is the difference between a clean determination and months of avoidable delay.

A statutory consultee can recommend that your application is refused, but in almost every case it cannot order the council to refuse it: the advice is a material consideration the authority has to weigh, not a veto.

What is a consultee in a planning application?

A consultee is any body or individual the local planning authority formally invites to comment on an application while it is being determined. Once an application is validated, the authority sends the plans and supporting documents to the relevant consultees and to the wider public, gathers their responses, weighs them against national and local policy, and then decides. Consultees supply expert advice on their own patch, whether that is flood risk, drainage, highways, heritage or ecology. The planning judgement itself belongs to the authority.

That distinction is worth labouring, because applicants often confuse a consultee with a decision-maker, and confuse a consultee with a consultant. The Environment Agency objecting to your flood risk assessment has not refused your application. It has advised the council, which must now weigh that advice. A drainage consultant you appoint to prepare your strategy is the opposite party again: they build the evidence the consultee will scrutinise. Keep the three roles apart and a planning process starts to read clearly.

Statutory, non-statutory and public consultation

Consultation in the English planning system runs on three tracks, and it helps to know which track a given response comes from.

• Statutory consultees are bodies prescribed in law that the authority must consult on specified types of development. The list sits in Schedule 4 of the Town and Country Planning (Development Management Procedure) (England) Order 2015, the DMPO 2015, which ties each kind of development to the body that has to be asked. The Environment Agency, the Lead Local Flood Authority and Natural England all appear on it.
• Non-statutory consultees are bodies not named in law but consulted because there is a genuine planning-policy reason to hear from them, such as a local wildlife trust, a design review panel or a neighbouring authority. This is the authority's discretion, not a legal duty.
• Public and general consultation covers neighbours, parish and town councils and the wider community, notified through site notices, neighbour letters and, for larger schemes, a press notice. Parish councils can ask to be told about applications in their area as of right.

Being statutory changes the duty to consult, not the power to decide. A statutory consultee has a seat at the table by law. It does not have the casting vote.

How does planning consultation work?

Once your application is validated, the authority runs a consultation window before it determines the case. Statutory consultees have a set period to give a substantive response: 21 days is the standard, reduced to 18 days for public service infrastructure applications made on or after 1 August 2021. If a consultee does not reply in time, the authority may go ahead and determine the application without its advice, because the wider determination clock, the 8, 13 or 16-week target, keeps running regardless.

Guidance is blunt that consultees should engage properly with that window rather than sit on it. As the Planning Practice Guidance puts it:

A consultee response tends to take one of four shapes: no objection; no objection subject to conditions, where the consultee asks for a planning condition to be attached and discharged later; a holding objection, where information is missing or insufficient and the concern lifts once you supply it; or a full, or maintained, objection, where the evidence is there but the scheme has not been shown to be acceptable. Working out which of the four you are looking at tells you whether you have a paperwork problem or a design problem.

Who are the statutory consultees?

The statutory list in Schedule 4 of the DMPO 2015 is long, and most applications only trigger a handful of the bodies on it. Alongside the flood and water consultees covered below, it takes in National Highways for development affecting the strategic road network, Historic England for heritage assets, the Health and Safety Executive for hazardous sites, the Coal Authority (now the Mining Remediation Authority) for land affected by past mining, Sport England for playing fields, and specialist bodies such as the Gardens Trust and the Theatres Trust. Which of them your council has to consult depends entirely on what you are building and where.

There is no single "statutory consultees list" that applies to every application. The DMPO 2015 ties each body to specific development types, so the consultees your scheme triggers are set by its nature and its location.

The flood, drainage and water consultees

For anyone building where water is a constraint, four or five bodies do almost all the work. This is the heart of the matter, and each has its own remit. Get the wrong body in your head and you answer the wrong question.

The two you will meet most often are the Environment Agency and the Lead Local Flood Authority, and applicants routinely muddle them. The Environment Agency leads on flooding from main rivers, the sea and reservoirs, and is consulted where a site sits in Flood Zone 2 or 3; when it is not satisfied, the result is usually an Environment Agency objection on flood risk grounds. The Lead Local Flood Authority became a statutory consultee on surface water drainage for major development on 15 April 2015. Major here means, broadly, ten or more dwellings, half a hectare or more of residential land, or 1,000 square metres or more of floorspace. Its concern is your drainage strategy, and an unresolved issue there becomes an LLFA objection.

Water and sewerage companies are the common surprise. They are consulted only in narrow, prescribed circumstances and are not statutory consultees on ordinary planning applications in England, even though sewer capacity and connection can make or break a scheme. They control connection and adoption through the Water Industry Act 1991, not through the planning consultation. If your site sits in an Internal Drainage Board district, the board is a statutory consultee in its own right. Where nutrient neutrality bites, Natural England's position on wastewater can hold up housing whatever the drainage design says. Wales works differently again: SuDS approval is mandatory there through a SuDS Approving Body under Schedule 3 of the Flood and Water Management Act 2010, and Natural Resources Wales is the flood-risk consultee in place of the Environment Agency.

Can a consultee refuse your application?

No, but advising rather than deciding is not the same as being powerless. A statutory consultee cannot refuse your application. A well-founded objection from the right body is still very hard for a council to set aside, because ignoring it exposes the authority to an appeal it may lose.

In 2024/25, 96% of English planning decisions complied with Environment Agency flood risk advice, rising to 99% for proposed new homes. An objection you cannot resolve is, in practice, close to fatal.

Flood risk carries an extra mechanism that sharpens the point. Under the Town and Country Planning (Flooding) (England) Direction 2007, an authority minded to grant permission against a sustained Environment Agency flood objection must notify the Secretary of State, who can call the application in and decide it centrally. That backstop is why an Environment Agency flood objection behaves, for planning purposes, almost like a block even though it is formally only advice. None of which means consultees run the system. It means the reliable route to consent is resolving their concerns on the evidence, not hoping the council overrides them.

The 2025-26 reforms to the statutory consultee system

The consultee system is being actively reshaped, and the direction of travel is fewer bodies and faster responses. On 10 March 2025 the government announced a review of statutory consultees and a moratorium on creating new ones. On 18 November 2025 it published a consultation, Reforms to the statutory consultee system, proposing to remove Sport England, the Gardens Trust and the Theatres Trust from the statutory list altogether and to cut the volume of unnecessary referrals elsewhere. The reasoning was delay: the government argued that a large share of referrals adds little, citing roughly 37% of Environment Agency referrals as unnecessary, often the result of a misread consultation trigger.

• What is being removed: Sport England, the Gardens Trust and the Theatres Trust are proposed to lose statutory consultee status, the first real pruning of the list in decades.
• What is being kept: the Environment Agency and the Lead Local Flood Authority stay statutory consultees, on the ground that flood and water risk carries genuine safety consequences.
• The wider aim: fewer automatic referrals and more proportionate, strategic engagement, as part of the drive to speed up planning decisions.

For a flood or drainage applicant the practical message is reassuring in one respect: the two consultees that matter to you are staying. The reforms also signal that authorities and consultees are under pressure to consult only where it counts, which makes getting your evidence right first time, so your scheme is not the one generating an unnecessary objection, more important rather than less.

What consultees mean for your application

Read the other way round, the consultee system is a list of the expert hurdles between validation and consent, and every one of them is easier to clear before you submit than after. Since the April 2026 planning appeal reforms, which largely bar new technical evidence at appeal, a weak flood risk assessment or drainage strategy can no longer be quietly fixed once you are refused. The case for front-loading the work is stronger than ever.

1. Screen the site early. Work out which consultees your scheme triggers, a Flood Zone for the Environment Agency, major development and surface water for the LLFA, an IDB district, a Welsh site for the SuDS Approving Body, before you design rather than after.
2. Commission the right evidence up front. A complete flood risk assessment or drainage strategy that answers the consultee's actual tests heads off the holding objection that stalls a determination.
3. Engage before you submit. A pre-application conversation with the relevant consultee is the single most effective way to surface a concern while you can still design around it.
4. Resolve, do not gamble. If an objection lands, answer it on the evidence rather than betting on the council to override it, and remember the appeal safety net has largely gone.

Done well, consultation is less an obstacle course than a checklist you can work through in advance. The applicants who struggle are usually the ones who meet their consultees for the first time in the objection.
