Briefing a specialist from an AI drafted starting point
A draft with its unverified facts flagged is a usable scope of works. Each flag is a question the specialist has to answer, and listing them produces better fee proposals than an email asking for a price.
Most fee proposals for specialist planning work come back non-comparable because the brief was three lines in an email. Briefing a specialist consultant properly takes an afternoon, and a drafted document is a reasonable way to spend that afternoon, because it forces you to state what the report has to conclude before you ask anyone to price it.
A PlanScope draft is an AI-assisted starting point. It cites policy, structures the sections a report of that type normally carries, and marks anything it cannot verify with a [TO BE CONFIRMED] flag. Those flags are the brief. Each one is a question the specialist has to answer, and listing them is a better scope of works than most clients produce unaided.
What a draft is good for at the briefing stage
Three things, and it is worth being clear about the limits.
It gives you the section structure the authority expects, so you can ask for a report that matches the validation requirement rather than a generic technical note. It gives you the policy hooks, so the specialist knows which local plan policy and which national test their conclusions have to speak to. And it gives you an explicit list of unknowns rather than an implicit one.
What it does not give you is data. No draft can tell you what the groundwater level is, whether bats are using the roof, or what the traffic flow on the access road is at 8:15am. For several report types a licensed or competent professional is legally required rather than merely advisable, including environmental impact assessment, protected species work, biodiversity net gain, land contamination and fire. In those cases the draft is a starting point for that professional, never a substitute for them.
Site information the specialist actually needs
Assemble this before you send anything out, because half of the price variation between proposals comes from consultants pricing uncertainty about the site.
A dimensioned site plan with the red line and any blue land shown, at a stated scale. The existing and proposed floor areas by use. The topographical survey if one exists, and a statement that one does not if it does not. Access arrangements and who owns the access. The planning history, with application references. Any pre-application advice received, in full rather than summarised. Existing reports on the site, including ones with unwelcome conclusions.
That last point is the one people get wrong. Withholding an earlier report that found something inconvenient does not make it go away. It makes the new consultant price for work that has already been done, and it creates a problem when the council's records turn the old report up.
Deliverables, dates and formats
Write the deliverable down as a physical thing rather than an outcome.
State the report title and the standard it is to be prepared under, naming the standard. State the number and format of drawings, and whether you need CAD files or PDFs. State whether figures have to be reproducible at A3. State whether an executive summary is needed. State the date for a draft for comment and the date for the final issue, and make those two different dates.
Then state what happens to the report afterwards. Will it be submitted to the council, published on the planning register, relied on by a purchaser, issued to a funder. Each of those has consequences for the consultant's insurance and for what they are willing to write, and consultants price differently when they know.
Our note on what a council asks when it wants to know who wrote your report covers the authorship question from the authority's side, and it is the same information the brief should fix in advance.
Reliance, copyright and who can rely on it
This is the section clients skip and lawyers add back.
Copyright in the report normally stays with the author unless the appointment says otherwise, and you get a licence to use it for the stated purpose. If you need the report for a different purpose later, that licence may not stretch.
Reliance is separate from copyright. A consultant owes a duty to their client. A purchaser, a funder or a joint venture partner who wants to rely on the report needs a reliance letter or a collateral warranty, and those cost far less to agree at appointment than to negotiate two years later when the consultant has moved firms.
Ask three questions in the brief. Who will the report be addressed to. Who may rely on it without further charge. What is the limit of liability and is it in line with the professional indemnity cover held.
Survey seasons and the programme risk they create
Ecology is where briefs collide with the calendar, and no amount of fee gets round it.
Bat emergence surveys run through the warmer months rather than year round, with a preliminary roost assessment possible at any time. Great crested newt environmental DNA sampling has a defined spring window. Reptile surveys work in spring and again in early autumn. Breeding bird surveys track the breeding season. Botanical survey needs plants to be identifiable.
Get the specialist to tell you, in the fee proposal, the earliest date they can complete each survey and what the consequence of missing this year's window is. Then build the planning programme backwards from that rather than forwards from today.
Non-ecological work has seasons too. Traffic counts should avoid school holidays and the December period. Parking surveys under the Lambeth methodology need midweek and weekend overnight counts outside holiday periods. Ground investigation gets harder and more expensive in a wet winter.
Comparing fees on a like for like basis
Put a pricing schedule in the brief so that every proposal comes back in the same shape.
- Desk study and data purchase, with data costs shown separately as a provisional sum.
- Site work, priced per visit, with the number of visits stated and the trigger for additional visits.
- Assessment and reporting.
- Consultee liaison, with an assumed number of exchanges.
- Attendance at meetings, priced per meeting.
- Response to consultation comments after submission, either included with an assumed effort or excluded and priced hourly.
Number five and number six are where a low headline fee becomes expensive. A fee that excludes any post-submission work will be tested the first time environmental health asks a question, and by then you have no competitive tension left.
If you are pricing the drafting work itself rather than the survey, PlanScope pricing is published, and the choice between a single report and the Professional tier depends on how many documents a scheme needs rather than on negotiation.
Reviewing what comes back
Read the report against the brief, in that order, before you read it for its conclusions.
Check that every [TO BE CONFIRMED] flag in the original draft has been closed out with data rather than with a form of words. Check the survey dates and effort against what the standard requires. Check that the policy the report cites is the adopted policy and the current edition of the Framework. Check the figures in the summary against the figures in the body, which disagree more often than anyone admits. And check the author's name and qualification against the person you appointed.
The factual errors to look for in a drafted planning document apply just as much to a consultant's final report as to a first draft. If something needs changing, send comments as a numbered schedule with the page and paragraph, and ask for a response column rather than a revised document with no explanation.
Where the draft is being used to open a conversation rather than to instruct, the approach in using a draft to prepare for a pre-application meeting works better than a cold enquiry, and the reviewer can be found through the professional directory once the scope is settled.
This is general guidance, not legal advice. For specialist technical reports, qualified professional input may be required. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
Frequently asked questions
Can an AI draft replace a specialist survey?
No. A draft can set out structure, policy and the list of unknowns, but it holds no site data. For environmental impact assessment, protected species work, biodiversity net gain, land contamination and fire statements, a licensed or competent professional is legally required. The draft is a starting point for that professional rather than a substitute.
What should a scope of works for a survey contain?
The decision the survey has to inform, the site boundary at a stated scale, the standard the work follows by name, the number of site visits, the deliverable format including drawing requirements, who handles consultee liaison, the draft and final dates, and the position on reliance. Without those, fee proposals are not comparable.
Why do fee proposals for the same work vary so much?
Usually because they include different things. One will include a data purchase, another will treat it as a provisional sum. One assumes two site visits, another one. The biggest gap is post-submission work, because a fee that excludes responses to consultation comments looks lower until the first query arrives.
What is a reliance letter and do I need one?
A reliance letter extends the consultant's duty of care to a third party such as a funder or purchaser who was not the original client. Copyright and reliance are separate from each other, and neither transfers automatically. Agree who may rely on the report at appointment, because negotiating it later is slower and more expensive.
How do survey seasons affect a planning programme?
Several ecological surveys have windows of a few months, and missing one can push a submission by a year. Ask each specialist for the earliest date they can complete the work and what happens if this year's window closes, then build the programme backwards from that date rather than forwards from today.
