Thurrock: U-Road Failures Have Nearly Tripled Since 2020
Thurrock Council's own condition data shows 25% of unclassified roads in RED condition in 2024/25 — up from 10% in 2020/21 — across 353km of residential network surveyed on a two-year rotation. The DfT rates overall performance AMBER, spend GREEN, but flags RED on best practice — while the council operates under Section 114 intervention restricting highways investment.
What the condition data shows
Five years of DfT-approved survey data from Thurrock's transparency report — A-roads recovering, residential roads deteriorating
A-roads (92km — 17% of network): best in five years
Principal roads intercepted by the M25, A13 and Dartford Crossing receive SCANNER laser surveys and close monitoring. The council states A-road condition is the best it has been in five years — but A-roads are less than one-fifth of the borough network.
B and C roads (107km — 19% of network): stable but amber rising
| Year | Red | Amber | Green |
|---|---|---|---|
| 2020/21 | 3% | 20% | 77% |
| 2021/22 | 3% | 18% | 79% |
| 2022/23 | 4% | 19% | 77% |
| 2023/24 | 4% | 21% | 75% |
| 2024/25 | 3% | 22% | 75% |
RED-condition B/C roads remain low at 3%, but amber roads have risen from 18% to 22% since 2021/22 — meaning roughly one in four classified local roads may need maintenance soon.
U-roads (353km — 64% of network): deteriorating sharply
| Year | U-roads in RED condition |
|---|---|
| 2020/21 | 10% |
| 2021/22 | 12% |
| 2022/23 | 19% |
| 2023/24 | 26% |
| 2024/25 | 25% |
RED-condition U-roads have risen two-and-a-half times since 2020/21. The council states scoring of the unclassified network can be subjective and that scores increased after its 2023 survey review — but also notes it has managed to slowly improve the network as the most recent scores indicate.
GREEN spend, AMBER roads
Thurrock's DfT capital allocation nearly tripled for 2025/26 — earning a GREEN spend scorecard. Yet only 6% of projected maintenance spend is preventative versus 12% reactive, and U-road carriageways face a 370-year renewal rate at current resurfacing levels. More money does not automatically mean better residential roads.
The 353km two-year survey cycle
How Thurrock measures road condition — and what changed in April 2023
Before April 2023
- • A and B class roads — 100% surveyed in both directions
- • C class roads — 100% surveyed in one direction
- • U class roads — 25% of network surveyed
From April 2023
- • A/B/C class roads — 50% surveyed in both directions
- • U class roads — 50% of network surveyed
- • Complete network survey every two years
“To accommodate for negative opinion around length of time to collect 100% of the Unclassified network which was creating questions around the validity of the data, the entire survey network for all categories was reviewed, and following changes were made from April 2023 (to fit budget allocation).”
— Thurrock Council Local Highways Maintenance Transparency Report (24 June 2025)
Why this matters for Section 58
To rely on the Section 58 defence, a council must show it had a reasonable system for knowing the condition of its roads. For Thurrock's unclassified network, ask:
- • When was your road last condition-surveyed — and was it in the surveyed or unsurveyed half?
- • If 25% of U-roads were RED at the last survey, what was done about yours specifically?
- • U-roads use coarse visual inspection — how does the council track defects between two-year surveys?
- • Did the 2023 methodology change affect comparability of condition records on your route?
A council surveying half its residential network each year cannot claim continuous knowledge of condition on every U-road at every point in the cycle.
Section 114 and the steady-state strategy
Thurrock's own explanation for constrained highways investment
“The Council is operating under intervention measure which directly affect our ability to pump additional funding into the Network and restricts to statutory, safety and/or spend to saving activities (Section 114). We have had to therefore rely upon our Asset Data and life cycling planning tools to focus our funding on holding the Highway Assets in a steady state.”
— Thurrock Council Local Highways Maintenance Transparency Report (24 June 2025)
What this admission means
Thurrock formally acknowledges that financial intervention restricts its ability to invest beyond holding highway assets in a steady state — not improving them. That is documented context for why U-road RED condition rose from 10% to 26% even as A-roads recovered.
The council combines reactive and preventative maintenance using a palette of treatment types, but under Section 114 constraints the priority is statutory safety — not network-wide improvement.
2024/25 treatment outputs
- • 7.6km / 54,000m² carriageway resurfaced
- • 4,166m² footway renewed
- • 19,599m² concrete carriageways micro-surfaced
- • 903 jet-patcher repairs over 45 roads
- • 3,295 pothole repairs — 98.86% within KPI timeframe
20,749 potholes in five years
Reactive repair volume on a network producing defects faster than preventative works can prevent them
| Year | Potholes filled |
|---|---|
| 2020/21 | 4,364 |
| 2021/22 | 3,888 |
| 2022/23 | 4,302 |
| 2023/24 | 4,900 |
| 2024/25 | 3,295 |
| Five-year total | 20,749 |
~200 verified reports per month
Thurrock reports an average of 200 verified potholes per month via inspections and public reports for 2024/25 (April–August data). That is roughly 2,400 reportable defects annually before council safety inspections add more — on a 552km network where defects routinely form between surveys.
2024/25 resource pressures
The council notes 2024/25 was a particularly challenging year due to resource constraints and change in organisational structure — yet still achieved 98.86% pothole repair KPI adherence. Lower repair counts reflect capacity limits, not absence of defects on the network.
Why best practice is RED
What Thurrock's own report reveals about asset management under financial intervention
370-year U-road renewal
At £858,000 capital for unclassified carriageways — resurfacing approximately 0.21% of the U-road network each year — Thurrock's own fact sheet calculates a 370-year renewal rate. Preventative resurfacing at scale on residential roads is structurally impossible at current levels.
6% preventative spend
Projected 2025/26 maintenance is only 6% preventative versus 12% reactive — down from 18% preventative in 2024/25. A network holding steady under Section 114 is running reactively, not getting ahead of deterioration.
Subjective U-road scoring
The council states U-road scoring can be subjective and uses coarse visual inspection rather than SCANNER laser technology. Scores rose after the 2023 survey review — the council acknowledges questions around data validity prompted the change.
AMBER condition, GREEN spend, RED best practice
Thurrock is not a low-spend authority in 2025/26 — but the DfT's RED best-practice flag sits alongside Section 114 constraints, a two-year survey cycle on 64% of the network, and U-road RED rates that have more than doubled. That matters when the council argues it could not reasonably have known about your defect.
Claiming against Thurrock's RED best-practice scorecard
Honest assessment: GREEN spend is real — but residential road condition and process gaps open specific angles
What works in the council's favour
- ✓ GREEN spend — DfT capital allocation nearly tripled to £3.819m for 2025/26
- ✓ A-road condition at its best in five years (4% RED, 73% green)
- ✓ 98.86% pothole KPI adherence in 2024/25
- ✓ Published Asset Management and Asset Maintenance strategies
- ✓ DfT-approved annual SCANNER surveys on classified roads
Expect a documented Section 58 defence on A-roads and major routes. Generic claims will struggle.
What works in yours
- ✗ RED best practice — DfT-flagged weaknesses in network management
- ✗ 25% of U-roads in RED condition — up from 10% in 2020/21
- ✗ 64% of network on two-year coarse visual survey cycle
- ✗ Section 114 intervention — council admits holding assets in steady state only
- ✗ 20,749 pothole repairs in five years — defects forming faster than prevention
- ✗ 370-year U-road renewal rate at current resurfacing levels
The winning strategy here is specificity
Against a council with GREEN spend but RED best practice, your claim lives or dies on the specific defect:
- • Prior reports of the same pothole (FixMyStreet, council highways tool) — proof of actual notice
- • Photos showing the defect's size, depth and visible age (weathered edges, previous patching)
- • The road's class — on a U-road, the two-year survey gap and 25% RED rate are structural arguments
- • Whether your route was in the surveyed or unsurveyed half of the network when damage occurred
Mac builds exactly this case: he searches for prior reports, assesses your photo evidence, and cites Thurrock's own transparency data where it helps you.

Frequently asked questions
Thurrock has a RED best-practice scorecard — can I still claim?
Yes. The DfT Best Practice rating is RED, and Thurrock's overall rating is AMBER — but your claim still turns on whether the specific defect that damaged your vehicle was reasonably inspected and repaired under Section 58. Thurrock's own report shows 25% of U-roads in RED condition, coarse visual inspections on a two-year rotation, and Section 114 intervention restricting highways funding.
What if my pothole was on a residential or unclassified road?
U-roads make up 353km — 64% of Thurrock's 552km network — surveyed via coarse visual inspection with 50% covered each year since April 2023. RED-condition U-roads rose from 10% in 2020/21 to 26% in 2023/24, settling at 25% in 2024/25 — roughly 88km of estate streets and local routes.
Does Thurrock's Section 114 financial situation affect my claim?
It can provide context. Thurrock states intervention measures directly affect its ability to pump additional funding into the network and restrict spending to statutory, safety and spend-to-save activities — its own explanation for holding highway assets in a steady state rather than improving them.
Thurrock earns GREEN on spend — does that block my claim?
No. The Spend scorecard reflects increased 2025/26 capital allocation (£3.819m DfT plus £5.26m other sources). Section 58 turns on the specific defect, not aggregate spend. Only 6% of projected 2025/26 maintenance is preventative, and U-road carriageways face a 370-year renewal rate at current levels.
Pothole repairs fell to 3,295 in 2024/25 — does that mean the roads are fixed?
No. Thurrock still filled 3,295 potholes with 98.86% KPI adherence, plus 903 jet-patcher repairs. The council notes resource constraints in 2024/25. An average of 200 verified potholes are reported per month, and the five-year total remains 20,749 repairs.
Do I have to report the pothole to Thurrock before claiming?
Thurrock investigates reports within three working days. Reporting via the online highways tool creates a dated record that strengthens your case if the defect was known before your incident or left unrepaired within a reasonable time. Keep your reference number and confirmation emails.
Why did Thurrock change its survey coverage in 2023?
The council revised survey lengths from April 2023 to fit budget allocation — 50% of A/B/C roads in both directions and 50% of U roads — ensuring a complete network survey every two years. The change followed negative opinion about the time to collect 100% of the unclassified network and questions around data validity.
