Bus infrastructure contributions and their triggers
Public transport contributions are among the least scrutinised heads of terms in a section 106 agreement. Here is what is usually sought, what the regulations require and where the drafting should be tightened.
A bus infrastructure contribution is a payment secured by planning obligation to provide or improve public transport serving a development, and every one of them has to satisfy the three statutory tests in regulation 122 of the Community Infrastructure Levy Regulations 2010. Those tests are the whole argument. A contribution that is necessary to make the development acceptable in planning terms, directly related to the development and fairly and reasonably related in scale and kind is payable. One that funds a deficiency the authority already had is not, however reasonable it sounds in a committee report.
What authorities usually ask for
The package varies by authority and by the size of the scheme, and it is usually assembled by the local transport authority rather than by the planning officer. Five items recur:
- Physical stop infrastructure: new or relocated stops, raised boarding kerbs, hard standing, flag and pole, shelter and seating
- Real time passenger information displays at the stops serving the site, sometimes with a commuted maintenance sum
- A subsidy to extend an existing service, divert it into the site or increase its frequency, for a defined period
- Bus priority or access works, such as a bus gate, a clearway or signal priority at a junction
- Free or discounted travel passes for first occupiers, usually for six or twelve months per dwelling
The last of those is sometimes treated as part of the travel plan rather than as infrastructure, and the distinction matters for how it is triggered and monitored. Our note on travel plan contributions and monitoring fees in section 106 covers that boundary.
Stops, shelters and real time information
Stop infrastructure is the least contentious element because it is measurable. A new stop pair needs a kerb build-out and a raised boarding kerb to allow level access from the footway to the vehicle floor, a hard standing area, drainage where the build-out interrupts a channel, lighting, a flag and timetable case, and a shelter where footfall justifies one. Bus stop clearway markings need a traffic regulation order, which the authority promotes and the developer funds.
Two things get missed. The order takes months and involves public advertisement and a possible objection period, so it should be programmed alongside the section 278 works rather than after them. And the stop cannot be delivered by the developer alone where it sits outside the site on the public highway, which means a section 278 agreement following the permission rather than a cash contribution, or both.
Where real time information is sought, ask what the display costs to install, what the annual data and power cost is, and how long the maintenance sum is meant to cover. A twenty year commuted sum for a display technology with a ten year life is not fairly related in scale.
Service subsidy and how long it runs
Subsidy is where the numbers get large and the justification gets thin. Authorities typically seek a revenue payment to support a diverted or extended service for three to five years, on the reasoning that patronage from the new development takes time to build and the operator will not carry the risk.
Ask three questions before accepting the figure. What is the marginal cost of the diversion, as opposed to the cost of the whole route? What patronage does the authority assume from the development, and does it match the trip generation in the Transport Assessment? And what happens at the end of the subsidy period, because a service that collapses in year six was never made commercially viable by the payment.
A tapering subsidy, higher in year one and falling as occupation completes, is easier to justify than a flat annual sum. So is a mechanism that pays against evidenced operator costs rather than a fixed figure, though authorities resist it because it is harder to administer.
The tests every contribution has to pass
Regulation 122 makes an obligation a reason for granting permission only where it is necessary to make the development acceptable in planning terms, directly related to the development, and fairly and reasonably related in scale and kind to it. The Planning Practice Guidance on planning obligations explains how authorities are expected to evidence that, and it also confirms that obligations should not be used to secure contributions towards items already funded through the Community Infrastructure Levy.
The pooling restriction that once limited authorities to five obligations per infrastructure project was removed in September 2019, so an authority can now pool freely. That makes the necessity and proportionality tests the only real discipline.
| Question to put to the authority | What good evidence looks like |
|---|---|
| Why is this necessary? | A named policy in the adopted local plan and a highway officer's assessment of the specific deficiency the development creates |
| How is it related to this site? | Walking distance to the nearest stop, the service frequency there, and the trip generation from the scheme |
| How was the sum calculated? | A published contributions formula or a cost estimate for identified works, not a round number per dwelling |
| Is it already CIL funded? | The authority's infrastructure funding statement and its list of infrastructure priorities |
Where the authority cannot answer the second or third question in writing, the head of terms is negotiable.
Trigger points, indexation and the base date
Drafting decides whether a contribution is manageable or a cash-flow problem. Payment before development starts is common for infrastructure works that have to be in place early. Payment on occupation of a stated number of units is more appropriate for subsidy, because the service is not needed before anyone lives there.
Set the trigger against something objective and capable of being evidenced: the date of a building control notice, the date of first occupation of the numbered plot, or a fixed number of days after a defined event. Avoid triggers tied to "substantial completion" without a definition.
Indexation should name the index, the base date and the frequency. A contribution indexed to a construction tender price index from the date of the resolution to grant behaves very differently from one indexed to consumer prices from the date of the agreement. On a scheme delivered over six years that difference can be material, so it is worth an hour of negotiation.
Illustrative example: a 180 dwelling scheme where the stop infrastructure sum is paid before work starts, the real time information sum on occupation of the 50th dwelling, and the service subsidy in three instalments on occupation of the 60th, 120th and 170th dwellings, each indexed from the date of the agreement. Figures and triggers here are illustrative only.
Spend-by dates and repayment clauses
Every contribution should carry a spend-by date and a repayment covenant. Five or ten years from receipt is the usual period. Without one, money sits unspent, and authorities are required to publish an infrastructure funding statement each year showing what was collected and what was spent, which makes unspent balances visible.
Draft the repayment clause to return unspent sums with interest, and define what counts as spent. A sum committed by contract but not yet paid out is usually treated as spent; a sum allocated in a budget line is not. Ask for the definition rather than accepting the authority's standard wording.
Also ask for a purpose clause narrow enough to be checkable. "Towards public transport improvements in the borough" is unenforceable in practice. "Towards the provision of two bus stops with shelters and raised boarding kerbs on the A road frontage, and diversion of service X into the site" can be audited.
Negotiating the package down to what is justified
Start from the Travel Plan and the transport evidence, because the contribution should follow the modal shift the scheme is actually relying on. If the transport case assumes 8 per cent of trips by bus, the bus package should be sized for that. If the case assumes almost no bus use, a large subsidy is hard to justify on necessity grounds.
Then look for double counting. Travel passes, real time information and a subsidy can all be sold to the committee as promoting bus use while overlapping in effect. And check whether the same works appear in the highway authority's capital programme, because a scheme already funded cannot be necessary.

Frequently asked questions
Can a council require a bus service subsidy as a condition?
A financial payment cannot be secured by condition, because conditions cannot require the payment of money. Subsidy is secured through a section 106 planning obligation instead. A condition can require a scheme or a travel plan to be submitted and implemented, and the obligation then funds the works or the service.
What are the three tests for a planning obligation?
Regulation 122 of the Community Infrastructure Levy Regulations 2010 requires an obligation to be necessary to make the development acceptable in planning terms, directly related to the development, and fairly and reasonably related in scale and kind to it. All three must be satisfied for the obligation to be a reason for granting permission.
Is there still a limit on pooling contributions from several developments?
No. The restriction that prevented an authority from pooling more than five obligations towards a single infrastructure project was removed in September 2019. Authorities can now pool freely, which makes the necessity and proportionality tests, and the annual infrastructure funding statement, the main check on how sums are gathered and spent.
When should a bus contribution be paid?
Match the trigger to when the item is needed. Stop infrastructure is usually paid before development starts because the works take time and may need a traffic regulation order. Service subsidy fits better on occupation triggers, in instalments, because the service carries no passengers until people move in.
What happens if the council never spends the money?
A well drafted agreement includes a spend-by date, commonly five or ten years, and a covenant to repay unspent sums with interest. Define what counts as spent, because a sum committed by contract is usually treated differently from one merely allocated in a budget. Authorities publish annual infrastructure funding statements showing receipts and expenditure.
