Carrying out works on the public highway comes with strict legal and safety responsibilities. Whether it’s installing utilities, repairing drainage, or adjusting ironworks, contractors must comply with the New Roads and Street Works Act 1991 (NRSWA).
Understanding NRSWA requirements for road openings and reinstatements is essential, not only to avoid penalties, but to ensure safe, durable, and high-quality results for road users and local authorities alike.
What Is NRSWA?
The New Roads and Street Works Act 1991 (NRSWA) govern all works carried out on public highways in the UK. It applies to contractors, utility providers, and developers working on or near the road network.
Its primary objectives are to:
- Maintain public safety
- Reduce disruption to traffic and pedestrians
- Ensure consistent, high-quality reinstatement of roads
- Protect the long-term integrity of the highway
Failure to comply can lead to fines, failed inspections, and costly remedial works.
What Is a Road Opening?
A road opening refers to any excavation or breaking of the highway surface to carry out works such as:
- Installing or repairing utilities (gas, water, electric, telecoms)
- Drainage installation or maintenance
- Accessing underground infrastructure
- Adjusting or replacing ironworks
Before any road opening takes place, contractors must follow strict procedures, including permits, notifications, and safety planning.
Key NRSWA Requirements for Road Openings
1. Permits and Notifications
Before starting work, contractors must:
- Apply for the correct street works permit
- Notify the local highway authority within required timescales
- Provide detailed plans of the works and traffic management
Failure to obtain permits can result in immediate penalties or work stoppages.
2. Qualified Operatives
All works must be carried out by NRSWA-accredited operatives and supervisors.
This ensures that everyone on-site understands:
- Safe excavation practices
- Traffic management requirements
- Proper reinstatement techniques
3. Traffic and Pedestrian Management
Maintaining safe movement around the site is critical. This includes:
- Appropriate signage, barriers, and lighting
- Safe pedestrian walkways
- Lane closures or diversions where necessary
Effective planning helps minimise disruption while keeping the public safe.
4. Safe Excavation Practices
Excavations must be carried out safely, with attention to:
- Underground utility detection (CAT & Genny surveys)
- Proper trench support and edge protection
- Safe access and egress for operatives
These measures reduce the risk of accidents, collapses, or service strikes.
NRSWA Requirements for Reinstatements
Once works are complete, the highway must be restored to a condition that meets strict national standards.
1. Specification for Reinstatement of Openings in Highways (SROH)
All reinstatement work must comply with the SROH, which sets out:
- Approved materials
- Compaction methods
- Layer thickness requirements
- Surface finish standards
2. Permanent vs Temporary Reinstatement
In some cases, a temporary reinstatement is installed first, followed by a permanent repair later.
- Temporary reinstatements must still be safe and traffic-ready
- Permanent reinstatements must meet full SROH compliance
3. Material Selection
Using the right materials is essential for durability.
Modern solutions like Pacopatch are increasingly used for ironwork reinstatements due to their:
- Strength and flexibility
- Resistance to water ingress
- Ability to withstand heavy traffic
4. Compaction and Finishing
Improper compaction is one of the main causes of failure.
NRSWA requires:
- Correct compaction of all layers
- Smooth, level surfaces
- Secure installation around ironworks
5. Inspections and Guarantee Periods
Reinstatement works are subject to inspection by the highway authority.
- Random inspections ensure compliance
- Failed works must be corrected at the contractor’s expense
- Works are typically covered by a guarantee period (2–3 years depending on the road type)
Common Risks of Non-Compliance
Failure to meet NRSWA requirements can result in:
- Financial penalties and fines
- Rejected works and re-installs
- Increased project costs
- Damage to reputation
- Safety risks for the public
