Five technical reports carry most UK planning applications — a daylight and sunlight report, a flood risk assessment, an air quality assessment, an energy statement and a sustainability statement. Applicants usually assume a specialist national body scrutinises each one. In reality only one of the five reliably reaches a statutory consultee. The other four are read by the case officer and the council's own in-house specialists.
That distinction decides how your evidence is challenged. A statutory consultee has a legal footing, a 21-day clock and — in the Environment Agency's case — an objection that a local planning authority will rarely set aside. An internal environmental health officer has none of those, but reads your report far more closely than most applicants expect. And on 17 August 2026 the government published its response to the biggest reshaping of the statutory consultee system in a decade, so the picture has just moved. This guide sets out, report by report, who reviews your evidence, what they look for, and what the 2026 reforms change.
Which planning reports reach a statutory consultee?
Statutory consultees are the bodies a council must consult in circumstances written into legislation — principally Schedule 4 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. There are roughly 27 of them. Notably, none of them exists to review daylight, energy or sustainability evidence on an ordinary application.
| Report | Who actually reviews it | Statutory consultee? | Typical trigger |
|---|---|---|---|
| Flood risk assessment | Environment Agency; lead local flood authority (surface water and drainage) | Yes — both | Flood Zone 2 or 3; 1 hectare or more in Flood Zone 1; land within 20 m of a main river; LLFA on major development |
| Air quality assessment | The council's environmental health / pollution control team | No — internal consultee | Site in or near an AQMA; traffic generation; demolition and earthworks dust |
| Daylight and sunlight report | Case officer, design or urban design officer, plus neighbour representations | No | Neighbouring windows affected; dense urban sites; local plan amenity policy |
| Energy statement | Council sustainability or climate officer; the GLA on referable London schemes | No — but GLA referral is its own statutory route | New dwellings or floorspace; London Plan Policy SI 2 |
| Sustainability statement | Council ecologist and policy officer; Natural England only where designated sites are affected | Mostly no | Local validation list; biodiversity net gain; London Plan Policy G5 |
The practical consequence: only the flood risk assessment is guaranteed an external technical audience with a statutory voice. Every other report has to persuade a generalist case officer who is reading a dozen documents against a validation list and a handful of local plan policies.
Who reviews your flood risk assessment?
Two bodies, and they look at different things. The Environment Agency is consulted on development in Flood Zones 2 and 3, on sites of one hectare or more in Flood Zone 1, and on land within 20 metres of a main river — broadly the same triggers that make an FRA necessary in the first place. It reviews river and sea flood risk, finished floor levels, the climate change allowance you applied, and whether the Sequential and Exception Tests have been addressed.
The lead local flood authority — the county council or unitary authority — is the statutory consultee on surface water drainage for major development. It reads the drainage strategy, the discharge rates, the SuDS hierarchy and the maintenance arrangements. Plenty of applications satisfy the Environment Agency on fluvial risk and then stall at the LLFA on greenfield runoff rates, which is why a drainage strategy and an FRA are not the same document.
The Environment Agency's own performance report shows the scale: in 2024 to 2025 it responded on 9,635 proposed developments, answering 88.3% within the statutory period or an agreed alternative. Fewer than one in ten responses runs late — so a weak FRA will normally be found, and found on time.
Who reviews your air quality assessment?
There is no national statutory consultee for air quality on a typical planning application. Your air quality assessment goes to the council's environmental health or pollution control team, who also run the authority's Local Air Quality Management duties. They know their own AQMA boundaries and monitoring data better than any consultant will, and they will check your background concentrations against the local diffusion tube results rather than accept a mapped value at face value.
They are typically looking for four things: correct Defra background data for the right grid square and year; the EPUK/IAQM significance criteria applied honestly; a construction dust assessment to IAQM guidance where demolition or earthworks are proposed; and mitigation that is deliverable rather than a list of aspirations. In London, add air quality neutral benchmarks under London Plan Policy SI 1.
Who reviews your daylight and sunlight report?
Nobody with a statutory duty — and this surprises people. A daylight and sunlight report is read by the case officer, sometimes by a design or conservation officer, and very often by the neighbour who objected. Neighbour publicity itself runs for 21 days, and a technically literate objection can carry more weight with a planning committee than the assessment it disputes.
Because there is no expert consultee, the report has to be self-explaining. Officers check that BRE BR 209 (2022) targets have been applied to the right rooms, that the 0.8 times rule has not been quietly reinterpreted, that VSC, NSL and APSH results are tabulated room by room, and that any shortfall is explained against the local plan amenity policy rather than buried. Where a council does have a daylight SPD or a validation requirement, that document — not national guidance — sets the bar.
Who reviews your energy statement?
Outside London, your energy statement is read by whoever the council has: a sustainability officer, a climate change officer, or in smaller authorities the case officer working from the validation checklist. They will check that the Part L 2021 baseline is a genuine notional-building comparison, that the Be Lean, Be Clean, Be Green savings are reported separately at each stage, and that the fabric measures claimed match the drawings.
In London the position is different. Applications referable to the Mayor — broadly 150 or more homes, buildings over 30 metres outside the City, and larger non-residential floorspace thresholds — are reported to the GLA at Stage 1 and Stage 2 against the GLA Energy Assessment Guidance. That is the closest an energy statement gets to statutory scrutiny, and it is unforgiving: the 35% on-site reduction target, whole life carbon reporting and any carbon offset contribution are all checked line by line.
Who reviews your sustainability statement?
A sustainability statement is usually read by the case officer and, for the ecology content, by the council's ecologist or a retained consultant. Natural England is a statutory consultee only in defined circumstances — principally where development affects a site of special scientific interest or another designated site. It is not consulted simply because your scheme claims biodiversity net gain.
Biodiversity net gain itself is checked twice: the council tests your metric and habitat baseline at application stage, then approves a biodiversity gain plan before development begins. Water efficiency is checked against the Part G calculation at 110 litres per person per day where a condition or policy applies, and in London the Urban Greening Factor is scored against Policy G5. Where a council asks for BREEAM, a licensed assessor — not the council — verifies the final rating, which is why a pre-assessment is the document that satisfies the planning condition.
What the August 2026 statutory consultee reform changes
The government consulted between 18 November 2025 and 13 January 2026 and published its response on 17 August 2026, drawing on 1,606 responses. The headline decisions:
- The Gardens Trust and the Theatres Trust lose statutory consultee status, replaced by notification arrangements without a 21-day response duty.
- Sport England is retained, contrary to the original proposal, but with referrals expected to fall by half or more — focused on major sports and school development and residential schemes affecting playing fields.
- National Highways, Active Travel England, Historic England and the Mining Remediation Authority keep statutory status with narrowed referral criteria, directing specialist input to higher-risk applications.
- The 21-day deadline is unchanged. The reform reduces the volume of referrals rather than extending the clock.
- Natural England and the Environment Agency remain, with £100 million committed to modernising environmental planning services and a forthcoming consultation on a planning fee surcharge to fund key consultees.
Regulations will follow "in due course" — no date has been fixed — so until they are made, the existing list applies. For the five reports covered here the direct impact is small: neither the Environment Agency nor the lead local flood authority is being narrowed. The wider signal matters more. Government is deliberately concentrating specialist scrutiny on the applications that need it, which raises the burden on the evidence you submit to speak for itself.
How long do consultees have to respond — and what if they miss it?
The standard consultation period is 21 days from receipt, or 18 days for public service infrastructure applications made on or after 1 August 2021, unless a longer period is agreed in writing. National guidance is explicit that if a consultee fails to respond in time, the authority may proceed to decide the application without that advice.
In practice authorities are cautious about doing so where flood risk is involved. An unresolved Environment Agency objection is very difficult for a council to set aside, and an application decided against it invites challenge. The realistic reading is that a late consultee delays you; an objecting consultee stops you.
| Stage | Period | What it means for you |
|---|---|---|
| Statutory consultee response | 21 days (18 for public service infrastructure) | Council may decide without the advice if it is late |
| Neighbour publicity | 21 days | Objections on daylight and amenity land here |
| Determination — householder / minor | 8 weeks | A re-consultation after amended reports usually consumes it |
| Determination — major | 13 weeks (16 with EIA) | Consultee comments typically arrive at weeks 3–5 |
How to write reports that survive consultee scrutiny
- Use live data and date it. Flood zone, AQMA and background concentration data all change. A report citing superseded mapping is the fastest route to a holding objection.
- Answer the policy, not just the standard. Officers assess against local plan policies. Quote the policy number and show compliance against it explicitly.
- Make shortfalls visible. A stated exceedance with reasoned justification is treated far better than one an officer discovers themselves.
- Keep the reports consistent. Contradictory floor levels between the FRA and the drawings, or a fabric spec in the energy statement that the elevations do not show, undermines every document in the pack.
- Check the local validation list first. It, not national policy, decides what your application must contain — see our validation checklist guide.
Frequently asked questions
Is a daylight report ever sent to a statutory consultee?
No. There is no statutory consultee for daylight and sunlight. The report is assessed by the case officer against the local plan's amenity policy, using BRE BR 209 (2022) and BS EN 17037 as the technical yardstick, and it is frequently scrutinised by objecting neighbours.
What happens if the Environment Agency objects to my application?
An objection is not an automatic refusal, but councils very rarely approve over a sustained Environment Agency flood risk objection. Most objections are resolved by amending the scheme — raising floor levels, revising the drainage strategy, or providing the missing modelling — and asking the Agency to withdraw it.
Can the council decide my application before a consultee replies?
Yes. Guidance states that where a consultee does not respond within the specified period, the authority may proceed to determine the application without that advice. Councils tend to use this for low-risk consultations rather than for flood risk.
Do the August 2026 reforms remove the Environment Agency or Natural England?
No. Both remain statutory consultees. Only the Gardens Trust and the Theatres Trust lose statutory status; several other bodies keep it with narrowed referral criteria.
Who checks biodiversity net gain?
The local planning authority, usually through its ecologist. It tests the metric at application stage and must approve a biodiversity gain plan before development starts. Natural England is consulted only where a designated site is affected.
Key takeaways
- Of the five core planning reports, only the flood risk assessment reliably reaches statutory consultees — the Environment Agency and the lead local flood authority.
- Air quality, daylight, energy and sustainability evidence is reviewed internally, by environmental health, the case officer or a sustainability officer — and in London by the GLA on referable schemes.
- Statutory consultees have 21 days (18 for public service infrastructure); if they miss it, the council may decide without their advice.
- The Environment Agency responded on 9,635 developments in 2024 to 2025, 88.3% of them on time — assume your FRA will be read properly.
- The government response of 17 August 2026 removes only the Gardens Trust and the Theatres Trust, narrows several other consultees, and leaves the 21-day deadline intact.
- Because most reports face a generalist reader, clarity, current data and explicit policy compliance matter more than technical depth alone.
How Fortress Associates can help
We prepare all five reports to the standard the reviewer applies. Our flood risk assessment is a free, site-specific report built on live Environment Agency data, following the Environment Agency's FRA template (March 2025) and CIRIA C753 for SuDS — the two documents the Agency and the lead local flood authority read against (England). Our air quality assessment is free and uses live Defra background maps, AQMA boundaries and DfT traffic data, applying EPUK/IAQM criteria and Defra LAQM.TG(22) — the same evidence base your environmental health officer uses.
Our energy statement is free and sets a Part L 2021 baseline on the SAP 10.2 notional-building method before working through the full energy hierarchy, including the London Plan Policy SI 2 35% target and offset position for London schemes. Our sustainability statement is free and covers energy, water efficiency at 110 l/p/d, 10% biodiversity net gain, urban greening and BREEAM where required. Our daylight and sunlight reports are prepared to BRE BR 209 (2022) and BS EN 17037, typically delivered in four to five working days with no advance payment.
