Building Regulation Consent - London Bylaws

Applying for building regulation consent in London, England requires following national Building Regulations while using a local authority building control service or an Approved Inspector. Local borough building control teams enforce technical standards for structure, fire safety, drainage and energy. This guide explains who enforces consent in London, which application routes to use, how to submit plans or notices, typical timelines, and how to appeal enforcement decisions. It focuses on practical action steps for homeowners, landlords and developers working anywhere in London.

How to apply

There are three common routes to obtain building regulation consent: a full plans application, a building notice, or a regularisation application for unauthorised work. Applications can be made to your local authority building control team or via an Approved Inspector; fees and exact procedures are set locally. For national guidance on application routes and when each is appropriate see the Planning Portal guidance and application pages Planning Portal - Building Control^[1].

Penalties & Enforcement

Local authorities and Approved Inspectors enforce compliance with the Building Regulations and may use statutory notices, prosecutions or stop notices where works breach the Regulations. Specific monetary penalty figures are not specified on the cited municipal guidance pages; see the official enforcement and local building control pages for case-specific detail City of London Building Control^[2].

• Non-monetary sanctions: enforcement notices, stop notices, remediation orders, requirement to remove or alter work to meet standards.
• Court actions: prosecution for failure to comply with an enforcement notice; orders to rectify or demolish unsafe work.
• Enforcer: local authority building control department or Approved Inspector; complaints and inspection requests go to the local council building control service or the Approved Inspector who issued the certificate.
• Time limits for enforcement or appeals: not specified on the cited page; check the enforcing body’s published procedures and statutory notices for exact deadlines.
• Defences and discretion: technical compliance, retrospective regularisation applications, or demonstrating a reasonable excuse may affect enforcement decisions; availability depends on the enforcing authority and the specific statutory powers used.

Applications & Forms

The nationally recognised application types are:

• Full plans application — submit detailed drawings and specifications; local authority checks and issues approval comments or conditions.
• Building notice — faster route for many domestic works where full plans are not required; inspections occur during works.
• Regularisation application — retrospective approval for work already done without consent; may require remediation.

Fees, submission methods and specific forms are published by each local authority; national guidance and application details are available via the Planning Portal application pages Planning Portal - Building Control^[1].

Common violations and typical outcomes

• Unauthorised structural alterations — enforcement notice requiring remedial work or approval via regularisation.
• Poor fire-separation or unsafe escape routes — immediate remedial orders and potential prohibition of occupancy until fixed.
• Inadequate drainage or retained fixtures — remedial works and re-inspection requirements.

Action steps

• Identify whether you need full plans, a building notice or regularisation; consult the Planning Portal and your local building control.
• Prepare or commission compliant drawings and specifications from a suitably qualified designer or engineer.
• Submit the application with payment to the local authority or instruct an Approved Inspector; arrange inspections as required.
• If you receive enforcement action, read notices carefully, note appeal deadlines and consult the enforcing department immediately.

FAQ

Do I always need building regulation consent for work in London?

Most structural work, material changes of use, and certain installations require consent; small non-structural repairs may not—check with your local building control service.

Can I use an Approved Inspector instead of the council?

Yes; Approved Inspectors can provide an alternative route to demonstrate compliance and issue a final certificate when work is complete.

What if work was done without consent?

You can apply for regularisation to obtain retrospective approval, but this does not prevent enforcement action; early engagement with building control is recommended.

How-To

1. Confirm whether your project is notifiable under the Building Regulations by checking the Planning Portal guidance.
2. Decide between a full plans application, building notice, or Approved Inspector route and collect required drawings and specifications.
3. Submit the appropriate application to your local authority building control or instruct an Approved Inspector and pay the fee.
4. Arrange and pass required inspections during construction; keep records of correspondence and inspection reports.
5. On satisfactory completion, obtain a final certificate or completion notice and retain it for sale or future works.
6. If enforcement action starts, note deadlines, respond promptly, and consider appeal or regularisation options with professional advice.

Key Takeaways

• Use full plans for complex projects and building notices for simpler domestic work.
• Contact your local borough building control early to avoid enforcement and delays.
