Start building the moment planning permission is granted, and there’s a real chance the entire project is technically unauthorised, even though permission itself was never in question. The catch sits in the conditions attached to that permission, and specifically in one category of them that has to be dealt with before a single brick gets laid.
What discharging a condition actually means
Almost every planning permission comes with conditions attached, requirements separate from the main approval that still have to be formally satisfied. Common examples include submitting a materials sample, providing a landscaping scheme, or confirming details of windows and boundary treatments. Completing the work described in a condition isn’t enough on its own. The council has to formally confirm, in writing, that each one has genuinely been met. That confirmation is the discharge, and it costs £89 for a householder application or £309 for any other application type.
Pre-commencement conditions, the ones that actually matter
Some conditions are marked pre-commencement, meaning they have to be discharged before any work starts on site, not just before the project finishes. This is where the real risk lives. Starting work before a pre-commencement condition is discharged can mean the development is unauthorised from day one, regardless of how solid the original permission was.
Why this trips people up more than it should
Permission feels like the finish line, so it’s an easy mistake to make: permission arrives, excitement takes over, and work begins immediately. Nobody checks whether any conditions needed sorting out first. It’s rarely negligence. It’s just that the conditions document doesn’t get read as carefully as the decision notice itself, and pre-commencement requirements can be easy to miss buried among several other, less urgent ones.
Why the fee is lower for householders
£89 versus £309 reflects the underlying complexity of what’s typically being discharged. Conditions attached to a home extension or alteration tend to be narrower and easier to assess, a materials match, a window detail, than conditions on commercial or multi-unit developments, which can involve drainage schemes, ecological surveys, or phased construction plans. The fee scales with the assessment work involved, the same logic that shapes most fees across the planning system.
Batching requests together genuinely saves money
If several conditions need discharging, submitting them together in a single application, to the same council, on the same permission, at the same time, means paying the fee once rather than once per condition. Submit them separately as each becomes ready instead, and each submission is charged individually.
Consider a householder extension with three conditions attached: matching materials, obscure glazing on a side window, and a landscaping scheme. Submitted together: £89 total. Submitted separately as each becomes ready: £89 multiplied by three, £267. The difference, nearly £180 in this example, comes down entirely to timing rather than anything about the conditions themselves.
What happens if a discharge request is refused
The council can refuse to discharge a condition if it decides the submitted details don’t actually satisfy what was required, materials that don’t match what was approved, for instance. A refusal allows resubmission with amended details, and in some circumstances an appeal similar to appealing a standard planning refusal. The fee already paid isn’t refunded either way, which makes getting the submission right the first time worth the extra care.
How this fits with the rest of the application process
Discharge of conditions almost always follows a householder application or a full application, rather than standing alone. It’s also distinct from varying or removing a condition entirely, a separate process with its own fee, used when a condition needs changing rather than simply confirming it’s been met. Confusing the two is a common source of submitting the wrong request to a council.
For anyone weighing up a full versus outline application, it’s worth knowing that outline permission in particular tends to generate more conditions at the Reserved Matters stage, since so much detail is deliberately left open at the earlier stage. Budgeting for discharge fees later in the process is easy to overlook when the focus is on the upfront application cost.
