Managing Construction Permits in the UK: A Site Manager's Guide

Construction in the UK requires a web of permits, approvals, and notifications that can trip up even experienced professionals. Missing a permit does not just cause delays; it can result in enforcement action, fines, or the requirement to demolish non-compliant work. This guide covers the key permits and approvals that affect UK construction projects and explains how site managers can stay on top of them.

Planning Permission

Planning permission is the most well-known approval in construction, but it is often misunderstood. Planning permission is about whether you can build something in a particular location, considering factors like land use, visual impact, traffic, and environmental effects. It is not about how you build it; that falls under building control.

When do you need it?

Most new buildings, significant extensions, changes of use, and alterations to listed buildings require planning permission from the local planning authority. Some minor works fall under "permitted development" and do not require a formal application, but the criteria are specific and often misapplied.

The site manager's role

By the time you arrive on site, planning permission should already be in place. Your responsibility is to:

• Read and understand the planning conditions attached to the approval. These may require specific materials, working hours, tree protection, archaeological watching briefs, or ecological mitigation
• Ensure that any pre-commencement conditions have been discharged before work starts. Starting work before pre-commencement conditions are satisfied is a breach of planning control
• Display the planning notice on site as required
• Monitor compliance throughout the project. If the design changes, check whether a variation to the planning permission is needed

Building Control Approval

While planning permission addresses the principle of development, building control ensures that the construction meets the Building Regulations. These cover structural stability, fire safety, energy efficiency, accessibility, drainage, and more.

Full plans vs building notice

There are two routes to building control approval in England and Wales. A full plans application is assessed in detail before work starts and provides certainty. A building notice allows work to start with just notification to the local authority, but carries the risk that the building control officer may require changes during construction.

Key building control inspections

• Commencement - notify building control before starting work
• Excavation for foundations - inspect before concrete is poured
• Foundation concrete - confirm the foundation is adequate
• Oversite preparation - before the ground floor slab
• Damp proof course - before covering up
• Drains - before backfilling (air test typically required)
• Structural frame - before cladding or enclosing
• Pre-completion / final inspection - before occupation

Give building control adequate notice for each inspection. Typically, this means at least 24 hours, though critical inspections like foundation excavations are often "hold until inspected." Proceeding without inspection can result in expensive opening-up requirements.

Section 80 Demolition Notice

Under Section 80 of the Building Act 1984, you must give at least six weeks' notice to the local authority before demolishing any building. The notice must include details of the building, the proposed method of demolition, and the measures to be taken for the safety of the public and adjacent structures.

Failure to serve a Section 80 notice is a criminal offence. It is one of the most commonly overlooked requirements, particularly on projects where demolition is a relatively small part of the overall works.

Party Wall Notices

The Party Wall etc. Act 1996 applies when your construction work involves:

• Work on a wall shared with an adjoining property
• Building a new wall at the boundary
• Excavation within specified distances of an adjoining property's foundations (three or six metres depending on depth)

Party wall notices must be served on the adjoining owner before work starts. If they do not consent, a party wall surveyor must be appointed. This process takes time, and failure to serve proper notices can result in injunctions stopping the work.

Street Works and Highways Permits

Section 171 (highway opening)

If your works involve breaking open the highway (kerb crossings, drainage connections, service connections), you need a Section 171 licence from the highway authority. Lead times vary by authority but allow at least four to six weeks.

Section 169 (hoarding on the highway)

If your hoarding or scaffolding encroaches onto the public highway, you need a Section 169 licence. This includes any temporary works, storage, or equipment on the pavement or road.

Temporary traffic management

Road closures, lane restrictions, and temporary traffic signals all require permits from the highway authority. Application lead times can be significant, particularly for road closures, which may need traffic management plans approved well in advance.

Environmental Permits and Notifications

Environmental permits

If your project involves discharging water (dewatering, surface water run-off) to a watercourse, you may need an environmental permit from the Environment Agency. This is particularly relevant for sites near rivers, streams, or sensitive ecological areas.

Waste management

Construction waste must be managed in accordance with the duty of care requirements. Ensure you have:

• Registered waste carriers for all waste removal
• Waste transfer notes for every load leaving site
• Hazardous waste consignment notes if applicable (asbestos, contaminated soil)

Protected species

If your site is home to protected species (bats, great crested newts, nesting birds), you may need a licence from Natural England before work can proceed. Ecological surveys are typically carried out during the planning stage, but the site manager must ensure that any mitigation measures are implemented on the ground.

Site-Specific Permits to Work

Beyond external permits, you should operate an internal permit to work system for high-risk activities:

• Hot works - cutting, welding, grinding, or use of open flames
• Confined space entry - any enclosed or partially enclosed space with foreseeable risks
• Electrical isolation - working on or near live services
• Excavation - any excavation deeper than 1.2 metres or near existing services
• Lifting operations - crane lifts, particularly complex or tandem lifts

Each permit should specify the work, the location, the duration, the controls required, and the person responsible. Permits should be displayed at the work location and formally closed out when the work is complete.

Keeping Track of Everything

The sheer volume of permits, approvals, and notifications on a construction project can be overwhelming. A permit tracker, whether a spreadsheet or a digital management tool, is essential. For each permit, record:

1. Type of permit or approval
2. Issuing authority
3. Date applied
4. Date received or expected
5. Conditions attached
6. Expiry date (if applicable)
7. Responsible person

Review the permit tracker weekly as part of your programme management routine. A permit that expires mid-project or a notification that is sent late can cause just as much disruption as a material shortage.

The cost of a permit application is almost always trivial compared to the cost of stopping work because you did not have one. Apply early, apply correctly, and track everything.
