Transport statement outline for a village shop conversion
A small conversion needs a transport statement, not an assessment. Here is what each section should contain and where the net trip comparison does the work.
A village shop conversion rarely needs a full transport assessment. It needs a transport statement outline that answers four questions in about a dozen pages: how many vehicle trips the new use generates compared with the old one, where people will park, how deliveries and refuse collection work, and whether the access is safe for the speeds on the road outside. Get those right and the highway authority raises no objection, which is all you need.
When a statement is enough
Planning Practice Guidance distinguishes a transport statement from a transport assessment by the scale of the likely transport impact. A statement suits development with modest trip generation where the issues can be set out without modelling. An assessment is for larger schemes where the network effects need testing.
The thresholds that matter in practice come from two places. National guidance points to the scale of the proposal, and PlanScope's own detector flags a Transport Assessment at 50 or more dwellings or 2,500 m² or more of floorspace. Councils' own validation lists then set local triggers, and a rural authority may ask for a statement on a scheme that an urban one would wave through.
For a shop of 80 to 150 m² converting to another use, or a vacant unit returning to retail, a statement is almost always the right document. Call the highway authority's development management team before writing it and ask what they want to see. Many will tell you.
Describing the existing site and access
Start with facts that can be checked on a site visit.
Record the existing use and its lawful planning status, the floor area, the current access arrangement with its width and surfacing, any on-site parking and its dimensions, the road classification and the speed limit, the presence of footways on either side, street lighting, and any waiting restrictions within a reasonable walk.
Then record what the road actually does rather than what the signs say. Measured vehicle speeds are better evidence than the posted limit, because visibility splays are designed to recorded speeds where those differ, and in a village with a 30 mph limit on a straight road the recorded speeds frequently sit above it. A short speed survey is inexpensive and settles the argument before it starts.
Photographs from the driver's eye position, looking both ways from the access, carry more weight than a paragraph.
Trip generation and the data behind it
This is the section that gets challenged, so show the working.
The usual source is the TRICS database, which holds surveyed trip rates for different land uses and site types. A statement should state the land use category used, the filters applied, the number of surveys in the sample and the resulting trip rates per unit of floorspace, for the relevant peak periods and for a daily total.
Then do the comparison honestly. The relevant figure is not the trips generated by the new use. It is the difference between the new use and the existing lawful use, because the existing use could resume without any permission. A village shop that has been trading, converting to a small cafe or to a dwelling, may generate fewer trips than the lawful baseline, and saying so clearly is the strongest point in the document.
Where the existing use has been vacant for years, the lawful use is still the baseline unless the use has been abandoned, which is a question of fact and degree and worth taking advice on.
Parking, servicing and refuse
| Item | What to show |
|---|---|
| Parking provision | Spaces, dimensions, surfacing, and the policy standard applied |
| Parking demand | Observed on-street occupancy across representative periods |
| Cycle parking | Stand type, number, location, and whether it is covered |
| Servicing | Vehicle type, frequency, where it loads, and for how long |
| Refuse | Bin store location, capacity, and the drag distance to the collection point |
Parking standards come from the development plan or an adopted supplementary document, and they are frequently maximum standards in accessible locations and minimum standards in rural ones. Quote the policy reference. Where provision falls short, an observed survey of on-street occupancy carries the argument far better than an assertion that the village has plenty of space. Where demand is seriously contested, a formal Parking Survey to a recognised methodology is the next step up.
Cycle parking is set by the same policy document, and the method for deriving the number from a policy standard is set out in the cycle parking calculation. Refuse is the detail most often missed on a small conversion. Collection crews will not drag bins more than a set distance, and the authority's waste team has a published figure. Check it and design to it.
Visibility splays and access geometry
State the design speed used and how it was derived. Draw the splays on a scaled plan with the X and Y dimensions dimensioned, show them clear of obstructions including hedges and parked vehicles, and confirm that the land within the splay is within the applicant's control or is highway.
Where the splay cannot be achieved, say so and explain the mitigation. Hedge reduction secured by condition, a change of access position, or evidence that the substandard splay has operated without recorded incident can all work. What does not work is drawing a splay that does not exist on the ground.
For a change of use with no alteration to the access, say that explicitly and give the reason the existing arrangement remains acceptable.
Walking, cycling and public transport
Keep this proportionate and specific. Distances to the nearest bus stop and the services it carries, the footway provision between the site and the village centre, whether there is a crossing point, the distance to the nearest primary school, and any public right of way passing the site.
Avoid the generic sustainability paragraph. A statement that says the site is in a sustainable location, with nothing behind it, invites the officer to disagree. A statement that says the stop is 180 m away with an hourly service to the market town on weekdays is a fact they can check.
A Travel Plan is not usually needed at this scale, and offering one you cannot monitor creates a condition you will struggle to discharge.
The summary table the officer wants
Finish with a single table setting out the existing use, the proposed use, the net change in trips at each peak and daily, the parking provided against the standard, the servicing arrangement and the conclusion on highway safety.
Officers read that table first and the rest only if it raises a question. Make it accurate, keep it on one page, and reference the paragraph in the body where each figure comes from.
PlanScope drafts a transport statement structured to UK planning policy, with the trip data, survey results and site measurements flagged as inputs to be supplied rather than invented. Councils usually expect a suitably qualified author for transport work on anything contested, so professional review is strongly advised. Browse the 66 report types to see what else a small change of use needs.
This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
When is a transport statement enough instead of an assessment?
Planning Practice Guidance distinguishes the two by the scale of likely transport impact. A statement suits modest trip generation where the issues can be set out without modelling. PlanScope's detector flags a transport assessment at 50 or more dwellings or 2,500 square metres, and councils set their own local triggers on validation lists.
What trip generation data should be used?
The TRICS database is the usual source. State the land use category, the filters applied, the number of surveys in the sample, and the resulting rates for the relevant peaks and the daily total. Show the comparison against the existing lawful use, not just the trips generated by the proposal.
Does the existing use count if the unit has been empty?
Normally yes. The lawful use remains the baseline for the trip comparison unless the use has been abandoned, which is a question of fact and degree turning on the period of non-use, the condition of the premises, any intervening use and the owner's intentions. Take advice where the point is contested.
How are visibility splays shown?
On a scaled plan with the X and Y dimensions marked, derived from measured vehicle speeds rather than the posted limit where the two differ, and clear of obstructions including hedges and parked cars. Confirm that the land within the splay is highway or within the applicant's control, and explain any shortfall rather than drawing a splay that does not exist.
Should a small conversion offer a travel plan?
Usually not. Travel plans carry monitoring obligations that are hard to discharge at this scale, and offering one creates a condition you may struggle to satisfy. Set out walking, cycling and public transport access with specific distances and service frequencies instead, which is what the officer is looking for.
