Bus service contributions secured by obligation

A bus service contribution under section 106 is a payment towards running a service, rather than towards building something. That distinction drives everything else about it. Infrastructure contributions buy an asset the authority keeps. A revenue contribution buys operating hours for a defined period, and when the money runs out the service stops unless somebody else funds it.

Which is why the first question on any request is not the amount. It is what happens in year four.

Why a contribution is sought

The planning reason is trip generation. A development in a location with an infrequent service, or none, generates vehicle trips the highway network has to absorb, and improving bus provision is one of the few measures that reduces them at source.

Requests typically arrive in one of three forms. Extension of an existing route into the site, usually with a turning facility and stops. Frequency improvement on a route already passing the site. Or a new service, which is the hardest to justify and the most expensive to sustain.

Local plan transport policies and parking standards supply the policy hook, and on larger schemes the authority may have an adopted supplementary document setting rates. Where the request comes without a policy reference, ask for one. A contribution that exists only in the highway authority's internal practice is answerable.

How the sum is calculated

The honest calculation is a subsidy gap. Take the annual cost of operating the additional service, subtract the fare revenue the service is projected to earn, and multiply the difference by the number of years the authority wants funded.

Each of those three inputs is contestable.

Operating cost should be built from the peak vehicle requirement and an annual cost per vehicle that the authority can evidence, not from a round figure. Fare revenue depends on patronage assumptions, and an authority assuming low patronage produces a larger subsidy gap, so the assumption needs stating. The funding period is a policy choice rather than a calculation, and five years is common while three and ten both appear.

Some authorities instead apply a published rate per dwelling. That is administratively simpler and more vulnerable, because a flat rate cannot show that the sum is related in scale to the particular development. Where a rate is used, ask what service it funds and for how long.

Infrastructure elements are separate and usually easier to agree: stops, shelters, raised boarders, real-time information displays and the highway works to accommodate a bus. Those have published cost bases, and they belong in the appraisal as a capital line.

The tests an obligation has to pass

Regulation 122 of the Community Infrastructure Levy Regulations 2010 limits what can be secured. An obligation must be necessary to make the development acceptable in planning terms, directly related to the development, and related in scale and kind to it in a way that is fair and reasonable.

Revenue contributions sit uncomfortably with the first limb. A contribution is necessary if the development is unacceptable without it, which means the transport evidence has to show a harm the service addresses. Where the transport assessment concludes the residual impacts are acceptable without any bus improvement, a contribution towards one is desirable rather than necessary, and that is the argument to make in writing.

The pooling restriction that once limited contributions to five obligations per project was removed in 2019, so an authority can now pool freely towards a service. That removed a defence applicants used to rely on. It did not change regulation 122, and the necessity test is the one that still does the work.

Duration, indexation and clawback

Four terms decide whether the deed is acceptable, and all four are negotiable.

1. Payment trigger. Tranches tied to occupation numbers match the arrival of the demand and spread the cash flow, which is preferable to a single payment when work starts.
2. Indexation. A sum indexed from the date of the agreement to the date of payment is normal; the index should be named, published and appropriate to operating costs rather than to construction costs.
3. Clawback. The deed should require repayment of any sum unspent within a stated period, commonly five or ten years from receipt, with interest. Authorities resist this less than developers expect.
4. Application. The money should be tied to a defined service or corridor rather than to the authority's general transport budget, so that the directly related test is satisfied on the face of the deed.

A fifth point is worth raising where the scheme is large. If the service is intended to become commercially viable, the deed can taper the subsidy across the funding period, which both reduces the sum and tests the authority's own patronage assumption.

Who runs the enhanced service

The authority does not operate buses. In most of England services are run commercially by operators, with the local transport authority procuring socially necessary services it chooses to support. The Bus Services Act 2017 added enhanced partnership and franchising powers, and where those are in place the procurement route and the authority's control over the service differ.

Three consequences follow for the obligation.

The authority needs to be able to spend the money lawfully on the service, which is a procurement question rather than a planning one. The operator can withdraw a supported service at the end of a contract period, so a commitment that the service will continue is not something the authority can give. And the development cannot be made conditional on the service existing, because neither party controls it.

That last point is the one to press when an authority proposes an occupation trigger tied to service delivery. The right structure is payment by the developer and delivery by the authority, with the same logic that applies to shared vehicle bays, covered in car club bays, securing them and keeping them viable.

Evidence that answers a request

A request met with assertion gets paid. A request met with evidence gets reduced or dropped. Five pieces of evidence do most of the work.

• Walk distances from the furthest dwelling to existing stops, measured along the actual route rather than as a radius.
• Existing service frequency and span of operation by day of week, taken from the published timetable.
• Trip generation for the development from an appropriate database or comparable site, with the mode share assumptions stated.
• The residual network impact with and without the bus measure, showing whether the measure is doing the work the authority says it is.
• Any published cost basis the authority holds, requested in writing before the obligation is agreed.

That analysis belongs in the Transport Assessment rather than in correspondence, because an inspector reading an appeal will look there. Councils normally expect that work from a suitably qualified transport planner and professional review of any draft is strongly advised. Where a school or other trip attractor is nearby, the catchment interaction matters too, and we look at it in school access, drop-off, school streets and restrictions.

An illustrative example of the shape of the argument: a 180 dwelling scheme on the edge of a town where the nearest stop is 650m from the furthest plot and the route runs hourly until early evening. The authority seeks funding for a half-hourly frequency over five years. The developer's answer is not to refuse, but to price a stop closer to the site, a footway link, and a shorter funding period aimed at the evening span rather than the daytime frequency, with the patronage assumption tested. That package usually costs less and does more.

Monitoring and reporting

Authorities must report annually on what they have received and spent through infrastructure funding statements, and those statements are published. Read the ones covering previous years before agreeing a sum, because they show whether earlier bus contributions in the area were spent, and on what.

Expect a monitoring fee as well, which covers the authority's cost of administering the obligation rather than the service. Keep it proportionate and tie it to defined administrative acts.

Where the obligation is paired with a Travel Plan, align the survey dates with the funding period so the monitoring data arrives while the subsidy is still running. A travel plan survey carried out after the money has been spent tells nobody anything useful.
