Council Building Regulations: A 2026 Guide to the Local Authority Route

Bhavesh Ramburn

What are council building regulations?

Council building regulations is a shorthand term for the Building Regulations work carried out by your local authority’s building control team. In England and Wales, every local authority is required to operate a building control service that enforces the Building Regulations 2010 (SI 2010/2214), made under the Building Act 1984.

The local authority’s building control team is responsible for:

  • Receiving building control applications (Full Plans or Building Notice).
  • Checking applications for compliance with the Building Regulations.
  • Inspecting work at key construction stages.
  • Issuing Completion Certificates on satisfactory completion.
  • Taking enforcement action where work does not comply with the Building Regulations.

Building control is separate from planning permission, which is a separate team within the same local authority and operates under different legislation. For the broader distinction between the two regimes, see our Building Regulations UK guide and our Building Control in the UK guide.

Which council handles building regulations?

In England and Wales, building control is delivered by the local authority in whose area the building work is taking place. The relevant local authority is the one covering the address of the site.

For most of England, the relevant local authority is the district council, London borough, metropolitan borough, or unitary authority for the area. The local authority’s building control team will be based in the council offices, although many authorities also offer online application services.

For a small number of types of work, building control is delivered by a private Approved Inspector rather than the local authority. The Approved Inspector registers the project with the local authority under the Initial Notice mechanism, then takes over the inspection function. For more on this, see our Building Control Initial Notice guide.

In Scotland, the equivalent regime is run by the local authority Building Standards team under the Building (Scotland) Act 2003. In Northern Ireland, building control is the responsibility of the district council under the Building Regulations (Northern Ireland) Order 1979.

The local authority building control process

The process of working with your local authority’s building control team typically follows these steps:

  1. Pre-application advice (optional). For complex or unusual projects, your local authority’s building control team can provide paid pre-application advice. This can save time and money by catching design issues before drawings are finalised.
  2. Application submission. Submit a Full Plans application or a Building Notice, with the required drawings and the application fee. The local authority’s building control team will validate the application and check it against the Building Regulations.
  3. Plans check. For Full Plans applications, the local authority has 5 weeks (or 2 months by agreement) to give a decision on the plans. For Building Notices, no formal plans check is required.
  4. Commencement of work. For Building Notices, work can start at least 48 hours after the notice is submitted. For Full Plans applications, work can start once the plans have been approved.
  5. Site inspections. The local authority’s building control inspector will visit at key construction stages: excavation of foundations, damp-proof course, oversite, pre-plaster, drainage test, completion.
  6. Completion Certificate. On satisfactory completion, the local authority issues a Completion Certificate. The Completion Certificate is an important document to retain for future house sales.

For more on the application process, see our Building Control Application guide. For the simpler Building Notice route, see our Building Notice guide.

Council building regulations fees

Local authority building control fees are set locally and published on the council’s website. The fees are typically based on the type and scale of the work, and are designed to recover the cost of the plans check and the site inspections.

As an indicative guide for 2026:

  • Extension (small, single-storey): from around £300 for a plans check + inspection.
  • Extension (large, multi-storey): £600–£1,200.
  • Loft conversion: £400–£800.
  • New build dwelling: £800–£1,500 depending on size and complexity.
  • Garage conversion: £300–£500.

The local authority’s fee schedule will be on the council’s website. For an LPA-specific worked example, see our Bradford building control guide.

For work that is carried out by a Competent Person (e.g. a Gas Safe registered engineer for boiler work, an NICEIC registered electrician for electrical work), the certification is recorded centrally and the homeowner is spared a separate local-authority application for that aspect of the work.

Council building regulations and planning permission

Council building regulations and planning permission are two separate services. A typical local authority has:

  • A planning department (sometimes called Development Management or Planning Services) that handles planning applications, planning enforcement, and policy.
  • A building control department (sometimes called Building Standards in Scotland) that handles Building Regulations applications, inspections, and enforcement.

The two teams typically share a single public-facing planning service page, with different contact details and application forms for each regime.

For most projects, both regimes will apply:

  • A new extension typically needs both planning permission and a Building Regulations application.
  • A new dwelling needs both.
  • A change of use typically needs both.
  • A small extension under Permitted Development may not need planning permission but does need a Building Regulations application.

For a single project, the two applications are separate and one can be approved without the other. However, in practice, work typically does not start on site until both are in place.

For the parallel planning-permission regime, see our householder planning permission guide and our Bradford planning portal guide.

The Building Regulations 10-year rule

A local authority cannot take enforcement action in respect of building work that has been substantially complete for more than 10 years. This is the 10-year rule under section 124 of the Building Act 1984. For more on this, see our Building Regulations 10-Year Rule guide.

The 10-year rule is a useful tool when buying or selling a property where Building Regulations documentation is incomplete. The rule is automatic and does not require a formal application.

Council building regulations and the Approved Inspector alternative

The local authority is not the only route to Building Regulations compliance. Approved Inspectors are private building control providers registered with the Construction Industry Council Approved Inspectors Register (CICAIR). An Approved Inspector can take over the building control function via the Initial Notice mechanism.

The advantages of using an Approved Inspector include:

  • Faster plans check — typically 5–10 working days versus 4–6 weeks for the local authority.
  • Competitive pricing — Approved Inspectors set their own fees and compete with the local authority on price and turnaround.
  • Continuity of service — the same Approved Inspector handles the project from application to completion.

The advantages of using the local authority include:

  • Local knowledge — the local authority knows the local development plan, the local ground conditions, and the local amenity issues.
  • No third-party fee — the local authority fee is typically lower than an Approved Inspector’s fee for most projects.
  • Larger inspection team — the local authority has more inspectors and can usually accommodate short-notice inspections.

For most ordinary projects, the local authority is the appropriate route. For more complex or time-critical projects, an Approved Inspector may be preferable.
