Timing, Approval and Getting It Wrong

Regulation 12(1) is specific: during the pre-construction phase, and before setting up a construction site. Not before starting the building work, before setting up the site. Site set-up itself is construction activity with its own risks.

Before the construction site is set up, per regulation 12(1). If hoarding is going up and welfare accommodation is arriving, the plan should already exist.

During the pre-construction phase, which is the period before construction starts when the design and planning work happens. Preparing it late defeats its purpose, because its function is to plan the arrangements rather than to record them afterwards.

In time for those who need to work to it, which in practice means before site set-up and before subcontractors begin. Because regulation 12(2) requires site rules, people cannot follow it if they have not seen it.

Regulation 12(4) requires the principal contractor to ensure it is appropriately reviewed, updated and revised from time to time throughout the project, so that it remains sufficient. The trigger is change: new phase, new risk, new contractor, changed method.

The regulation says from time to time throughout the project rather than setting an interval, with the test being whether the plan remains sufficient. In practice that means reviewing at each significant change and at planned intervals appropriate to the project, on competent advice.

Yes. Regulation 12(4) requires ongoing review, updating and revision throughout the project. A plan written once and filed does not satisfy the regulation.

The duty is framed around construction projects and the principal contractor's role, so the question is usually whether the activity is construction work at all, and who is the contractor. That is a legal question rather than a judgement call, so get competent advice rather than relying on a general answer.

It varies by authority. The Royal Borough of Kensington and Chelsea states it can take up to eight weeks to approve a CTMP, depending on the quality of the submission and the complexity of the project. Quality is the part you control: an incomplete first submission generates a request for information and restarts the clock.

The local planning authority, on advice from the highway authority, and the approval takes the form of formally discharging the condition. In Kensington and Chelsea, for example, the Department of Planning and Place must formally discharge the application.

If the CTMP is required by a pre-commencement condition, starting work puts you in breach. Kensington and Chelsea states plainly that if you start work before the CTMP is discharged, they could take enforcement action. This is a matter for legal advice rather than a risk to take on site judgement.

Not always. Some authorities offer pre-application advice, but others draw a firm line: Kensington and Chelsea states that while its Planning Advice Service can assist in preparation, it is not possible to meet contractors or review drafts of CTMPs before a formal application is submitted. Check what your authority offers before relying on a pre-submission review.

Yes. Where a project sits on the Transport for London Road Network, additional liaison with TfL is needed for licences including scaffold permits, separate from the planning authority's CTMP process. Two consenting bodies means two timescales, and they are best started together.

Usually a planning condition, discharged by the local planning authority. Separately, the physical activities it describes often need highway licences and permits, such as scaffolding licences, skip permits, hoarding licences and parking suspensions. Approving the plan does not grant those permissions.

No, and this is a common and expensive misunderstanding. The CLP guidance makes the analogous point about holding areas: inclusion in an approved CLP does not remove the right of the appropriate highway authority to suspend such use if the area is on their network. Planning approval and highway consent are different things.

It depends on the condition. Some authorities want an outline version with the application and a detailed version before work starts, mirroring the Outline and Detailed structure the CLP guidance uses. Others require the whole thing pre-commencement. The decision notice tells you which.

If it is a pre-commencement condition, it must be submitted and approved before any work begins. That is the whole point of the phrase pre-commencement, and it is why leaving the document until the contractor is appointed often delays the programme.

Because regulation 12 requires it, and because planning the health and safety arrangements before setting up a site is what prevents the arrangements being improvised once work has started.

It is the document that turns intentions into site rules people can actually follow. Regulation 12(2) requiring site rules and regulation 12(4) requiring ongoing review together make it the operational health and safety record for the build.

Usually a request for further information, which costs weeks rather than money. Occasionally worse: if a pre-commencement condition remains undischarged because the submission did not address it, work started in the meantime is work started in breach. Matching the document to the condition wording avoids both.

Sometimes, if it genuinely addresses both and the authority agrees. Ask the case officer first. Assuming it and submitting one document against two conditions is a common way to end up with one discharged and one not.

They are worded to require approval before development begins, or before any work starts on site. The decision notice is the authoritative source. Read the conditions in full rather than the summary, because the timing is in the wording.

Frequently yes, because the plan has to demonstrate that the vehicles serving the site can physically use the proposed access. A statement that a given vehicle can enter and leave is an assertion; a swept path drawing is evidence. Many authorities will not discharge the condition without it.

There is no statutory bar on it. The practical question is whether it will be approved first time, because the cost of a refused submission is measured in weeks of delayed site start. Where a scheme is higher impact, the CLP guidance points toward input from a construction logistics specialist, and CLOCS recommends CLP Practitioner Accreditation for those writing logistics plans.

Submit a complete first application. That means using the authority's pro-forma if it has one, answering every question including marking genuinely inapplicable ones as not applicable, including the routing plan and the swept path evidence, and naming who is responsible for each commitment. Almost all delay in this process comes from incomplete first submissions rather than from the authority being slow.
