Almost half of sampled applications to discharge planning conditions were not decided within the normal eight-week period, according to new research published by the Home Builders Federation (HBF) on 23rd October 2026. Its Condition Impossible report, produced with Paragon Development Finance, found that only 50.8% were determined on time.
The findings matter because a planning permission often comes with further approvals to obtain before building starts, work progresses or homes can be occupied. Those extra approvals are known as discharging conditions. Delays at this stage can hold up homes that already have planning permission, particularly where drainage, highways or site investigations need other bodies to respond.
For anyone relying on a consented site, I would regard these figures as a warning against treating permission as the end of the planning timetable. The research is an indicative sample, not a national league table of councils, but it describes a problem that can affect borrowing costs, construction contracts and the date a development can lawfully begin.
Planning conditions: what the figures actually show
The HBF obtained information through Freedom of Information requests covering more than 14,000 discharge applications over the three financial years beginning 2023/24. It asked for residential pre-commencement, pre-foundation and above-ground condition decisions, including how many were made within eight weeks. Some councils could not separate housing applications or provide the requested breakdown, so the results should not be read as a comprehensive national assessment.
Across that sample, 50.8% of applications were determined within eight weeks. That leaves 49.2% outside the usual period. The on-time proportion fell from 55.6% in 2023/24 to 51.8% in 2024/25. Those two complete-year figures support the report’s warning about worsening performance, but the partial 2025/26 data should not be presented as directly comparable.
There was considerable variation between authorities. Some determined more than 75% of the sampled applications on time, while others managed only 18%. A separate set of determination-time responses, supplied by 30 authorities, produced a median time of 70 days for the incomplete 2025/26 period, compared with a normal 56-day target. The different samples and time periods are important when interpreting those numbers.
What a missed deadline can cost a housing scheme
The effect of slow decisions on planning conditions is especially serious where a condition expressly prevents work from starting until the council has approved particular details. It may relate to drainage, contamination, ecology, construction management or the design of access. A developer cannot safely assume that obtaining outline or detailed permission is enough to make a lawful start.
The HBF report includes a developer-supplied account from Eastbourne involving an approved 250-home development. It says a drainage-related condition submitted in February 2025 was not approved until September 2026, roughly 19 months later, after repeated engagement with the lead local flood authority. That is a case study presented by the developer, not an independently established finding of fault against the council.
In another example from Bristol, the report says 23 completed social-rent homes could not be occupied while a pre-occupation condition involving highway matters remained unresolved. It also describes a Nuneaton scheme of 14 homes with 25 conditions, where one application made in April 2025 was still being only partially resolved in March 2026. Such accounts show why a decision notice can be only one milestone in the housing delivery programme.
HBF chief executive Neil Jefferson put the problem plainly: “Securing planning permission should be a major step towards getting homes built”, before warning that late condition decisions create costs and uncertainty. His remarks accompanied the 23rd October announcement.
What the eight-week rule means in England
For discharge applications in England, government planning guidance explains that the council normally has eight weeks, beginning the day after receipt, to give notice of its decision. A longer period may be agreed in writing. Where the approval is required before development involving an environmental impact assessment can begin, the period is generally 16 weeks instead.
Importantly, planning conditions do not automatically disappear because eight weeks have passed. Some approvals can be treated as given under the deemed discharge process, but only if the condition qualifies and the applicant serves the required notice at the correct stage. There are important exclusions, including categories of environmental and technical conditions. A refusal or non-determination may alternatively support an appeal.
Our guide to discharging conditions explains the standard application, the clock and the danger of starting work too soon. The separate deemed discharge guide covers the notice procedure and its exclusions. I would read both against the actual wording and date of the individual permission before relying on a procedural remedy.
What the research does and does not prove
The HBF’s analysis raises important questions about the performance of decision-making on planning conditions after permission is granted. However, the underlying Freedom of Information responses were not uniform. Some authorities reported aggregate decisions rather than the specific residential categories requested, while others could not extract complete figures. It is therefore wrong to claim that precisely half of all councils missed their target, or that the percentage establishes a national failure rate for every type of planning permission.
The report also does not establish the cause of every late decision. A complex submission, missing technical evidence, responses from other consultees and staffing pressures can all affect progress. The HBF argues for a national system of recording discharge times, better resourcing and more standardised conditions. It separately cites staffing shortfalls, but its condition-discharge requests did not ask councils to explain each delay.
This distinction matters when a project runs into difficulty. I would examine the validated application date, subsequent submissions, any agreed extension, the condition wording and the exchanges with technical consultees. The date alone identifies a potential delay; it does not prove that all the responsibility rests with one party.
Practical steps before starting work
The immediate lesson is to review planning conditions as soon as a decision notice arrives. Identify every pre-commencement and pre-occupation requirement, who must provide the evidence and whether a third-party approval is likely. Gather technical material early and keep a dated record of valid applications, council requests and any agreement to extend the time.
Where a condition seems unnecessary or impossible to satisfy, consider the correct statutory route rather than ignoring it. The difference between varying a condition, appealing a refusal, seeking deemed discharge and simply submitting better details can determine whether works proceed lawfully. Our overview of planning conditions explains their legal purpose and the limits on what councils may require.
For developers and housebuilders, planning conditions are not an administrative afterthought. They are part of the critical path from consent to occupation. The HBF’s new evidence does not replace a site-specific assessment, but it gives an evidence-based reason to budget more time and question avoidable delay well before the construction start date.
