What This Requirement Covers
Building Control bodies charge fees for processing applications, inspecting building work, and issuing completion certificates. The fees vary depending on the type and complexity of the work, and whether you use the local authority or a Registered Building Control Approver.
Key Requirements
Fee Structure
Local authority Building Control fees are typically split into
- Plan charge: Payable when the application is submitted; covers the assessment of plans
- Inspection charge: Payable when work commences; covers site inspections and the completion certificate
- Building notice charge: A combined charge payable when the building notice is submitted
Typical Fees (Indicative, 2024)
Fees vary by local authority, but typical ranges are
- Small domestic extension (under 40 m²): GBP 400-600
- Large domestic extension (40-100 m²): GBP 600-900
- Loft conversion: GBP 400-600
- Garage conversion: GBP 300-500
- New dwelling (single house): GBP 800-1,200
- New dwellings (multiple): GBP 500-800 per unit (reducing scale for larger developments)
- Replacement windows (via Building Control, not FENSA): GBP 150-250
- Electrical work (via Building Control, not competent person scheme): GBP 200-300
- Regularisation: Typically 100-150% of the standard fee
- Commercial projects: Individually quoted based on project value and complexity
RBCA Fees
- Registered Building Control Approvers set their own fees, which are negotiable
- RBCA fees may be lower or higher than local authority fees depending on the project type
- RBCAs often offer a fixed fee for the entire service (plan assessment and inspections)
VAT
- Local authority Building Control fees are exempt from VAT
- RBCA fees are subject to VAT at 20%
Practical Compliance Tips
- Obtain a fee quote before choosing between the local authority and an RBCA
- Factor Building Control fees into the project budget from the outset
- The plan charge is non-refundable even if the application is withdrawn or rejected
- Regularisation fees are higher than standard fees; it is always cheaper to apply for approval before starting work
- Some local authorities offer a discount for online applications
- For large or complex projects, negotiate the fee with the local authority or RBCA before submitting the application
- The fee covers the service, not the outcome; a rejection or additional inspections do not automatically incur extra charges (though this varies by authority)
