Financial year end and section 106 monitoring budgets

Section 106 monitoring fee timing is one of those details that looks administrative until it lands. The fee is usually payable before development starts, in a single sum, at the point when the developer's outgoings are already at their heaviest and nothing has been sold. Add indexed infrastructure contributions triggered by the same event, and a site can face six figures of obligation payments in the month the hoarding goes up.

None of that is a reason to resist the obligations. It is a reason to negotiate the triggers and the indexation base date with the same attention you give the contribution amounts, because the timing is often worth more than the headline figures.

How contributions are usually triggered

Almost every obligation in a section 106 agreement hangs off one of a small number of events.

1. Before development starts, judged by reference to material operations under the 1990 Act.
2. Prior to first occupation of any dwelling.
3. On occupation of a specified dwelling, commonly the 25th, 50th or 75th.
4. On practical completion of a phase or of the whole development.
5. On a calendar date, which is rare and usually a drafting error.

The pattern that causes trouble is a cluster of payments all tied to the start of works. Education, open space, highways, health and monitoring all fall due before the first brick is laid, and the finance for the scheme has to carry them through to first receipts.

Spreading those triggers across occupation milestones is the single most useful commercial change available in a section 106 negotiation, and authorities will often accept it where the drafting keeps the total secure. What they will resist is anything that leaves a contribution payable after the last unit is sold, because at that point the developer may have nothing left to enforce against.

Indexation clauses and the payment date

Indexation looks like boilerplate and it is where the money moves. Three variables matter.

Which index applies. Construction cost and tender price indices behave differently from consumer price measures, and over a long build out the divergence is material.

What the base date is. An obligation indexed from the date of the agreement accrues for longer than one indexed from the date of the planning permission or from a stated base date, and on a scheme that sits unimplemented for three years that difference is real.

And whether indexation runs to the trigger date or to the actual payment date. If it runs to the payment date, a late payment costs the developer twice: interest on the arrears and further indexation on the principal.

Read those three together before signing. A contribution of a stated sum "index linked" with no base date and no index named is an invitation to argue later, and the argument is resolved in the authority's favour more often than not.

Monitoring fees and when they fall due

Monitoring fees were put on a clearer footing by amendments to the Community Infrastructure Levy Regulations 2010, which allow a planning obligation to require a sum towards the cost of monitoring and reporting on the obligations. The tests in the regulations still apply: the fee has to be necessary, directly related to the development, and fairly and reasonably related in scale and kind.

In practice fees are calculated either as a percentage of the total obligation value, or per obligation, or per monitoring event, and the basis varies between authorities. Ask which basis is being used and ask for the calculation. A percentage-based fee on a large contribution can look disproportionate to the actual monitoring work, and that is a legitimate point to make by reference to the regulatory tests rather than as a general complaint.

Where monitoring is charged per event, ask what those events are. A fee covering an annual site visit for ten years is a different proposition from one covering two compliance checks.

Year end and council spending deadlines

Local authorities run to a financial year ending 31 March, and they report on obligations annually through an infrastructure funding statement covering the preceding financial year. That reporting duty gives the obligations team a calendar of its own.

Two practical consequences follow for developers. Payments received late in the financial year may sit unspent, and where the agreement includes a clawback clause the clock on that starts from receipt rather than from the start of the following year. And requests for compliance information tend to cluster in the months before the statement is published, so a developer who cannot evidence which triggers have been met will be chased at the busiest point in their own programme.

Keep an obligations schedule from the day the agreement is signed: each obligation, its trigger, the amount, the index and base date, the date satisfied, and the evidence. It takes an hour to set up and it saves a week every year. Our note on section 106 payment triggers across a financial year goes further into how the triggers themselves interact with the calendar.

Late payment and interest provisions

Most agreements provide for interest on late payment at a stated margin over a reference rate, running from the trigger date rather than from a demand. That means a payment missed because nobody noticed a trigger had been met accrues interest silently.

Enforcement is stronger than developers sometimes assume. A planning obligation is a local land charge and binds successors in title, so an unpaid contribution follows the land. The authority can sue for the sum as a debt and can seek an injunction to restrain breach of a restrictive obligation, and in the meantime an unsatisfied obligation shows up on a search and stops a sale.

The practical risk is therefore less about the interest and more about discovering the problem at the point of disposal.

Cash flow planning around trigger points

Illustrative example: a 60 unit scheme where the original draft required the monitoring fee, the highways contribution and half the education contribution before work started, totalling a sum the developer would carry for fourteen months before first completions. The revised agreement moved the education payment to occupation of the 20th and 40th dwellings and split the monitoring fee into two instalments, leaving the highways payment at the start of works because the works were needed for site access. Figures here are illustrative.

Three principles make that kind of renegotiation work.

Tie each payment to the event it funds. A contribution towards a school place is needed when people move in, not when the topsoil is stripped. That argument has force because it goes to the regulatory tests rather than to convenience.

Keep the authority secure. Offer a bond, a parent company guarantee or a restriction on further occupation rather than simply asking for a later date.

And show the cash flow. An authority presented with a dated schedule of receipts and payments can see the problem. One told that the timing is difficult cannot.

Where viability is the underlying issue rather than timing, that is a different conversation and it needs evidence: a Viability Assessment prepared to the recognised professional standards, where councils expect a suitably qualified author and professional review is strongly advised.

Renegotiating a trigger

An agreement can be varied by deed at any time with the authority's consent, and section 106A of the Town and Country Planning Act 1990 provides a formal route to modify or discharge an obligation, with an application available after five years from the date of the agreement.

In practice the informal route is faster. Approach the obligations officer with a specific proposed variation, a reason grounded in the regulatory tests, and an offer of security. Do it before the trigger is breached, because renegotiating an obligation you have already failed to perform starts from a weaker position.

Budget for the authority's legal costs on any variation, and for the time: a deed of variation takes weeks rather than days, and it will not be signed the afternoon before you need it. Sequencing survey and evidence spend around the same calendar is the companion problem, and our note on planning a survey budget across two financial years covers it.
