What This Requirement Covers
Building Control inspectors regularly encounter the same types of non-compliance across domestic and commercial projects. Understanding the most common violations helps designers, builders, and homeowners avoid costly remedial work and delays.
Key Requirements
Top 10 Most Common Violations
- Missing or incorrect fire stopping: Service penetrations through fire-resisting walls and floors not properly sealed
- Inadequate means of escape: Travel distances exceeded, fire doors not self-closing, missing emergency egress windows in bedrooms
- Poor drainage installation: Insufficient gradient, joints not properly made, drains not tested before backfilling
- Insulation gaps: Thermal insulation not continuous at junctions (especially around windows, at eaves, and between floors and walls)
- Structural openings without approval: Load-bearing walls removed or openings formed without a structural engineer's design or Building Control consent
- Inadequate ventilation: Missing trickle vents in replacement windows, no extract fan in bathrooms, inadequate kitchen ventilation
- Electrical work without notification: Notifiable electrical work carried out without Building Control notification or competent person certification
- Foundation depth insufficient: Foundations not deep enough for the ground conditions or proximity to trees
- Staircase non-compliance: Incorrect rise and going, inadequate headroom, missing handrails or guarding
- Missing completion certificates: Work completed without final inspection or sign-off
Enforcement Options
Building Control has several enforcement options
- Informal advice: Request remedial action
- Section 36 notice (Building Act 1984): Formal notice requiring the removal or alteration of non-compliant work; the owner has 28 days to comply or appeal
- Prosecution: For failure to comply with a Section 36 notice or for carrying out building work without approval
- Injunction: Court order preventing occupation or requiring specific remedial work
Practical Compliance Tips
- Use the Building Control pre-application service if you are unsure whether your project requires approval
- Do not assume that a builder knows the Building Regulations; verify key compliance items yourself
- Request Building Control inspections at the key stages; do not skip inspections to save time
- Photograph critical construction stages (foundations, fire stopping, insulation) before they are concealed
- Do not occupy a building or open a business before the completion certificate is issued
- Address any Building Control queries promptly; unresolved queries accumulate and delay sign-off
- If you inherit non-compliant work from a previous owner, apply for regularisation to resolve it
