Budgeting the discharge of pre-commencement conditions

Pre-commencement conditions are the reason permissions sit unbuilt. A decision notice lands with 14 conditions, four of them worded "before development takes place", and each of those four needs a document, a fee, and eight weeks of the council's time before a digger can move. On a single plot that is typically a few thousand pounds of consultant work and three to four months of programme. Budget it as a stage in its own right, sitting between permission and start on site, with its own money and its own dates.

Identifying the conditions that block a start

Read the decision notice with a highlighter and sort every condition into three piles.

Conditions precedent are those requiring approval before any development begins. They are the ones that stop you. Conditions requiring approval before a later stage, such as before the building is occupied or before external materials are installed, can be dealt with during construction. And compliance conditions require no submission at all, only that you build as approved.

The wording matters more than the numbering. "No development shall take place until" is a condition precedent. "Prior to the commencement of above-ground works" binds the superstructure but allows groundworks, which is a distinction worth arguing for when the notice is drafted rather than after.

Since section 100ZA of the Town and Country Planning Act 1990 came into force, a local planning authority cannot impose a pre-commencement condition without the applicant's written agreement. The procedure in the Town and Country Planning (Pre-commencement Conditions) Regulations 2018 requires the authority to give you notice of the proposed condition, with a period to respond. That notice is your one chance to move a trigger, and it is usually 10 working days. Diarise it from the moment you submit, because it arrives near the end of the determination period when everyone is relieved and not reading carefully.

Which conditions need a consultant report

Most pre-commencement conditions fall into a short list, and the cost of each is driven by whether it needs site work or only desk work.

A Construction Management Plan and a materials schedule are documents you can produce and submit in a week. A contamination or archaeology condition is a programme item measured in months, because the field work has to be commissioned, executed, reported and then approved.

Ecology is the one with a hard calendar. A licence application for bats cannot be made without survey data from the right season, and a mitigation condition that needs a licence can hold a site for the best part of a year if the permission lands in October.

Fees, consultant costs and the time each takes

There are three cost lines and people usually budget only one.

The application fee for approval of details reserved by a condition is set nationally per request, indexed annually on 1 April, so check the current fee schedule rather than an older figure. Grouping several conditions into one request saves fees, and it also means one slow condition holds up the others, so group by theme and by likely approval date rather than putting everything in one envelope.

Consultant fees are the larger line. Where PlanScope helps is the drafting layer: documents such as a construction management plan, a drainage statement or a method statement structured to policy, with the missing site facts flagged rather than invented. See PlanScope pricing for what that layer costs. For anything requiring intrusive investigation or a licence, the qualified professional is doing the work and their fee is the fee.

The third line is the council's time. Eight weeks is the normal determination period for a discharge application, and authorities under pressure use all of it. Assume eight weeks per round, plus a round of comments, and you are at three months for a condition that needs any negotiation.

Negotiating the trigger before the notice is issued

The cheapest money you will ever spend on conditions is the hour you spend on the draft conditions before the decision is issued.

Ask the case officer for the draft conditions and propose three changes. Move anything that does not need to precede groundworks to a later trigger, such as before above-ground works or before first occupation. Convert a condition requiring approval of a scheme into a condition requiring compliance with a submitted scheme where the detail already exists. And ask for conditions to be grouped so one submission covers a theme.

Officers accept these more often than people expect, because their concern is control rather than sequencing, and because section 100ZA makes them ask you anyway.

Working at risk and what it exposes you to

Starting work before a condition precedent is discharged is not a technical slip. The established position is that operations carried out in breach of a condition precedent do not count as lawful commencement of the development, so the permission can expire unimplemented while you have a half-built structure on site.

That leads to three exposures. The development may be unauthorised, so enforcement is available. The permission may lapse, leaving you applying again under whatever policy then applies. And a warranty provider, funder or purchaser's solicitor will find it, which turns a planning problem into a transaction problem.

There is a partial safety net. Section 74A of the 1990 Act allows a deemed discharge notice for certain conditions where the authority has not determined the request in time, and the condition is then treated as discharged. It does not apply to everything, notably where another body's sign-off is required or on EIA development, so check the exclusions before relying on it. Retrospective regularisation is the expensive alternative, as set out in the note on the cost of putting retrospective development right.

Sequencing discharges against the build programme

Build the discharge programme backwards from the date you want to start.

1. Week 0, permission issued. Sort conditions into the three piles the same day.
2. Week 1, commission anything needing site work: infiltration testing, trial pits, topographic survey, intrusive contamination investigation.
3. Weeks 2 to 6, draft the desk-based documents and submit the first grouped request.
4. Weeks 4 to 10, field work and reporting for the site-based conditions.
5. Week 10, submit the second grouped request.
6. Weeks 10 to 18, determination, comments and approval.
7. Before start, serve any commencement notice and check that the levy exemptions are in place.

Utility connections run in parallel and have their own lead times, covered in the note on utility connection costs in a development budget.

An illustrative budget for a small site

Illustrative example only, for a two-plot site with six conditions, four of them precedent. The shape of the budget is what matters rather than the figures, which vary by region and by consultant.

The four precedent conditions were materials, arboricultural method statement, drainage details and a construction management plan. Two needed site work: infiltration testing and a topographic survey. Two discharge applications were submitted, three weeks apart, each with its own fee. The infiltration results came back poor, which forced a redesign to an attenuated discharge and a second round of comments from the lead local flood authority.

Elapsed time from decision notice to final approval: 19 weeks. Cost: two application fees, two days of survey work, a drainage redesign, and the drafting of three documents. The item nobody had budgeted was the redesign, which is the usual story, so hold a contingency against the condition whose outcome depends on a measurement you have not taken yet.
