Discharging pre-start conditions in time for a spring start

If you want to be on site in March, the condition discharge applications need to be with the council before Christmas. That is the arithmetic: eight weeks for the council to determine an application under article 27 of the Development Management Procedure Order 2015, plus the fortnight around Christmas when nothing moves, plus whatever time your consultants need to produce the details in the first place. Self-builders who discharge conditions before starting work in spring almost always start the process in autumn, and the ones who leave it to January are still waiting at Easter.

The ones who start anyway are taking a larger risk than they realise.

Identifying which conditions bite before work

Read the decision notice and sort every condition into three groups. Conditions precedent have to be satisfied before development begins, and they usually open with wording such as "no development shall take place until". Pre-occupation conditions bite later. Compliance conditions run for the life of the development and have nothing to discharge.

Only the first group controls your start date. On a typical single dwelling consent that group is smaller than people expect and usually covers materials, levels, drainage details, tree protection, an ecological mitigation strategy, a construction management plan and sometimes archaeology. Everything else can wait.

Two conditions sit outside this list and catch people out. The biodiversity gain condition is a deemed condition under Schedule 7A to the Town and Country Planning Act 1990, so it appears on the permission whether or not the officer mentioned it, and the gain plan has to be approved before development begins. And a condition tied to a section 106 obligation may require a payment or a trigger to be met that the council tracks separately from the planning file.

The statutory period and what it really means

Article 27 gives the authority eight weeks to determine an application for approval of details reserved by condition. Eight weeks from validation, not from posting.

Validation is where the time goes. A discharge application submitted without the required plan, without the fee, or referencing condition numbers from a superseded permission sits in a queue until someone notices. Quote the application reference, the date of the decision notice and the condition number in the covering letter, and attach only the documents that condition asks for.

Where the council misses the period, section 74A of the 1990 Act allows a deemed discharge notice in some cases, with several categories of condition excluded from the route. It is a backstop rather than a plan. Lenders and warranty providers are generally happier with a written confirmation than with a deemed discharge, so treat it as something you hope not to use.

Submitting in batches rather than one by one

The fee for a discharge request is charged per request, not per condition. Submitting six conditions in one application costs the same as submitting one, and submitting them separately costs six times as much and gives the case officer six files to open.

So batch by readiness, not by subject. Put everything you can evidence now into the first application and hold back only the conditions that really do depend on later information. A second batch four weeks later is fine. Six batches is money thrown away.

One caveat. Where one condition depends on the approval of another, for example a construction management plan that has to reflect an approved tree protection plan, submit them together in the same application rather than in sequence. The officer can then consider them as one package.

Conditions needing third party input

These are the ones that break programmes, because the eight week clock keeps running while you wait for someone outside the council.

Ecology is the one that turns a delayed start into a lost year. Emergence surveys for bats run from May to September, great crested newt environmental DNA sampling runs from 15 April to 30 June, and botanical surveys for a habitat condition assessment need the growing season. A condition requiring a protected species survey or an updated habitat baseline cannot be discharged in February by paying more. The season is the season, which is why botanical survey season and habitat condition assessment is worth reading before the permission is even granted. Works near a ditch or river bring their own window, covered in water vole survey season and works near a watercourse.

What counts as a lawful start

Section 56(4) of the 1990 Act defines the material operations that begin development. They include any work of construction in the course of erecting a building, demolition, digging a trench for foundations, laying an underground main or pipe into a foundation trench, constructing a road, and a material change of use.

Setting up a site hut is not on the list. Nor is clearing vegetation, fencing the boundary or delivering materials. That distinction matters in both directions: it means a permission close to expiry can be implemented with a modest operation, and it means the work you thought was harmless preparation may not have preserved anything.

Risks of starting before discharge

Two consequences, one procedural and one structural.

The procedural one is a breach of condition notice, which the authority can serve under section 187A of the 1990 Act and against which there is no appeal to the Planning Inspectorate. The structural one is worse. Following the principle in Whitley v Secretary of State for Wales, works carried out in breach of a condition precedent are not a lawful start at all, so the permission can run out underneath a half-built house. The Court of Appeal applied that reasoning in Greyfort Properties v Secretary of State for Communities and Local Government, where an undischarged levels condition meant the permission had never been implemented.

Beyond enforcement, there is the money. Warranty providers, lenders and buyers' solicitors ask for written confirmation that conditions precedent have been discharged. A self-build mortgage stage payment can stall on exactly that question, and the council will not backdate a confirmation to suit a drawdown date.

Working back from the intended start date

Count backwards from the day the excavator arrives.

1. Start date, minus two weeks for the written confirmation to arrive and be circulated to the contractor and the lender.
2. Minus eight weeks for the statutory determination period, and add two weeks if the period spans the Christmas closure or Easter.
3. Minus three to six weeks for your consultants to produce the details, longer for a drainage strategy that needs infiltration testing.
4. Minus whatever the third party consultee needs, taken from the table above rather than from optimism.
5. Minus the survey season, if any condition depends on ecology, and treat that as fixed.

For a March start on a scheme with a drainage condition and a tree protection condition, that lands the submission in the first half of November. For a scheme with an outstanding ecology condition it lands the survey work in the previous summer. Enter the dates in a calendar rather than a head.
