Section 278 agreements.
Getting Section 278 highway works from planning consent to completion: scope, design, approval and the agreement, with fewer surprises on cost and programme.
Also known as: Section 278, S278, Section 278 agreement, highway works agreement
What’s included.
A Section 278 agreement under the Highways Act 1980 allows a developer to carry out works on the existing public highway, such as a new access, footway or junction improvement. The highway authority approves the design, charges fees and requires a bond.
- Scope of works from the planning consent
- Preliminary and detailed design coordination
- Road Safety Audits
- Technical approval
- Fees, bonds and commuted sums
- Liaison through construction and handover
Straightforward, proportionate, agreed early.
Know the scope early
Off-site works defined at planning stage, so costs are known before you commit.
Consistent
The S278 design follows what planning approved, so nothing goes back to committee.
Kept moving
Prompt responses to the council, because S278 delays hold up occupation.
