Lambeth: One-Third of A-Roads in RED, Just 16% Green
Lambeth earns GREEN for spend — projecting £9.3m in capital works against a £585,000 DfT allocation. Yet the overall rating is AMBER, and the council's own report admits its most trafficked roads are collapsing: at the 2024 survey, 33.18% of A-roads were in RED condition while only 16.46% remained green — on a 354km network where 75% of carriageway is residential streets surveyed only every other year.
33.18%
A-roads in RED condition (2024)
Up from 21.86% in 2020 across Lambeth's 44km of A-roads. The council itself reports a 10% rise in poor-rated main roads over five years and a 19% fall in green-rated A-roads since 2023.

What The Condition Data Shows
Five years of RAG condition data from Lambeth's own transparency report — main roads failing, residential streets sliding into amber
A-roads (44km — 12.4% of network): deteriorating fast
| Year | Red | Amber | Green |
|---|---|---|---|
| 2020 | 21.86% | 46.16% | 31.98% |
| 2021 | 27.03% | 37.29% | 35.64% |
| 2022 | 27.03% | 37.29% | 35.64% |
| 2023 | 33.18% | 49.68% | 16.46% |
| 2024 | 33.18% | 49.68% | 16.46% |
More than four-fifths of Lambeth's A-roads are now amber or red. Good-rated main roads have halved since 2020 — from 31.98% to 16.46%.
B and C roads (46km — 13% of network): steady decline
| Year | Red | Amber | Green |
|---|---|---|---|
| 2020 | 14.73% | 36.61% | 48.66% |
| 2021 | 16.03% | 35.8% | 48.17% |
| 2022 | 16.03% | 35.8% | 48.17% |
| 2023 | 15.63% | 44.57% | 39.8% |
| 2024 | 15.63% | 44.57% | 39.8% |
Green-rated B/C roads have fallen from 48.66% to 39.8% — a 9% drop the council attributes to insufficient funding for robust resurfacing on classified roads.
U-roads (264km — 75% of network): amber surge
| Year | Red | Amber | Green |
|---|---|---|---|
| 2020 | 19.99% | 33.16% | 46.85% |
| 2021 | 17.14% | 36.9% | 45.94% |
| 2022 | 17.14% | 36.9% | 45.94% |
| 2023 | 9.74% | 55.58% | 34.66% |
| 2024 | 9.74% | 55.58% | 34.66% |
RED U-roads fell, but more than half are now AMBER — sub-optimal, not acceptable. Good-rated residential streets dropped 12% since 2020. On 264km of local roads, that is roughly 26km still in RED and 147km in amber condition at the 2024 survey.

Estimated preventative share
Lambeth projects spending nearly 16 times its DfT allocation on capital highways works — yet A-roads in RED condition rose 10% in five years. The problem is not the budget line on paper. Heavily trafficked classified roads are deteriorating faster than resurfacing keeps pace.
The Biennial Survey Gap
How Lambeth measures road condition — and what it does not capture between surveys
Boroughwide Survey Every Two Years
Lambeth collects condition data through a boroughwide survey every two years. Assets are assessed with five condition grades, convertible to the traditional three-grade RAG status reported to the DfT. Published figures repeat in consecutive years — 2021 matches 2022, and 2023 matches 2024 — indicating fresh network-level data only on alternate years.
The council uses an accredited supplier and reports it is well prepared for the forthcoming BSI PAS 2161 national methodology shift.
Routine Inspections vs Network Surveys
Between formal surveys, the authority relies on routine and ad-hoc inspections. Carriageway and footway defects are repaired following either routine or ad-hoc inspections. For 2025/26, Lambeth states the highway network will be routinely inspected and defects risk-assessed before reactive repairs are arranged.
Section 58 turns on whether that inspection regime was reasonable for the specific road where your pothole formed — not on the boroughwide survey scorecard alone.
Why This Matters For Section 58
To rely on the Section 58 defence, Lambeth must show it had a reasonable system for knowing the condition of its roads. On a network where 75% is unclassified residential streets, ask:
- • When was your road last condition-surveyed — 2023/24 or an earlier cycle?
- • If 55.58% of U-roads were amber at the last survey, what was done about yours?
- • Did routine inspections catch the defect before it damaged your vehicle?
- • On an A-road where 83% are amber or red, was inspection frequency adequate for traffic volume?
A council cannot point to a biennial network survey and claim continuous knowledge of every defect forming in between.
2,709 Carriageway Potholes in Five Years
Lambeth's published pothole-fill counts — structural binder and surface course repairs only
| Year | Potholes filled |
|---|---|
| 2020 to 2021 | 306 |
| 2021 to 2022 | 374 |
| 2022 to 2023 | 692 |
| 2023 to 2024 | 729 |
| 2024 to 2025 | 608 |
| Five-year total | 2,709 |
2025/26 Projection: 676 Potholes
Lambeth estimates it will fill 676 carriageway potholes in 2025/26. That is roughly 1.9 per day across 354km — a modest count for inner London, but each repair confirms defects are forming and being treated reactively rather than prevented.
Structural Impairment Only
The council categorises these repairs according to when binder and surface courses were structurally impaired. Surface defects below that threshold may be repaired but not counted in the DfT pothole table — so the published figures understate total defect activity.
Five Years of Highways Spending
Capital, revenue, and the preventative-reactive split from Lambeth's own figures
| Year | DfT allocation | Capital spend | Revenue spend | Preventative | Reactive |
|---|---|---|---|---|---|
| 2020 to 2021 | £0 | £4,573,912 | £1,450,380 | 76% | 24% |
| 2021 to 2022 | £0 | £6,268,950 | £1,462,755 | 80% | 20% |
| 2022 to 2023 | £0 | £6,562,201 | £1,531,180 | 81% | 19% |
| 2023 to 2024 | £180,000 | £6,000,000 | £1,833,863 | 75% | 25% |
| 2024 to 2025 | £180,000 | £5,300,000 | £1,719,709 | 75% | 25% |
| 2025 to 2026 (projected) | £585,000 | £9,305,323 | £1,779,684 | 85% | 15% |
HAIP Capital Programme
Lambeth primarily uses its Highways Asset Improvement Programme (HAIP) capital funding for resurfacing schemes on carriageways and footways. Some capital has also gone to the Golden Jubilee Footbridges. For 2025/26, the council plans to resurface 2.17 miles (3.5km) of carriageway and improve 18 footways.
17:3 Preventative Ratio Planned
For 2025/26, Lambeth states the split between preventative and reactive works will be a ratio of 17:3. DfT funds are planned to contribute towards preventative treatments measuring up to 4.2 miles in length, subject to feasibility and budget allocation.
Lambeth's Own Condition Admissions
What the council says about deteriorating roads — in its own words
"The condition data highlights the deterioration of Lambeth's most trafficked roads. The percentage of A class roads that are in a poor (red) condition has increased by 10% over five years. Since 2023, there has been a 19% decrease of green (good) rated A class roads, demonstrating how heavily trafficked roads are the most susceptible to damage."
— Lambeth Council Local Highways Maintenance Transparency Report 2025
"B and C class roads are also steadily declining, with a 9% fall in roads rated as 'green' or good. Without funding for robust resurfacing schemes, classified roads (including A, B, & C) will deteriorate further, falling into a serviceable condition before ultimately becoming poor."
— Lambeth Council Local Highways Maintenance Transparency Report 2025
"Unclassified roads, which constitute the majority of Lambeth's network, are essential for local journeys. They have similarly deteriorated since 2020, showing a 12% decline in roads rated as 'good.' Preventative maintenance treatments (such as Micro Asphalt) on these lower trafficked roads could prevent costly future repairs and keep them in an acceptable condition."
— Lambeth Council Local Highways Maintenance Transparency Report 2025
What These Admissions Mean
Lambeth formally acknowledges that its classified roads are deteriorating and that without robust resurfacing funding, they will fall further into poor condition. That is documented knowledge of elevated risk on the borough's busiest routes.
Knowledge of accelerating wear on A-roads raises the standard for what a reasonable inspection frequency looks like under Section 58.
Questions Worth Asking
- • Was your pothole on an A-road where a third of the network is already RED?
- • Did the council increase inspection frequency as condition worsened?
- • If deterioration was known, why was the specific defect not caught before it caused damage?
- • Was micro-asphalt treatment planned for your residential street — and did it happen?
829 S81 Notices in 2024/25
Third-party street apparatus failures — a rising enforcement workload Lambeth documents itself
| Year | S81 notices issued |
|---|---|
| 2019/20 | 324 |
| 2020/21 | 542 |
| 2021/22 | 376 |
| 2022/23 | 291 |
| 2023/24 | 487 |
| 2024/25 | 829 |
| Total (six years) | 2,849 |
"When defective street apparatus—such as damaged covers —is identified, the Highways Service issues a Section 81 (S81) notice under NRSWA 1991. This compels the responsible statutory undertaker to inspect and repair the fault within a set timeframe. S81 notices support asset management by ensuring third-party infrastructure is safely maintained, reducing risk and shifting repair costs away from the authority."

Claiming Against a Well-Funded AMBER Council
Honest assessment: Lambeth invests heavily — here's how that changes your approach
What Works In The Council's Favour
- ✓ GREEN spend scorecard — projects nearly 16 times its DfT capital allocation
- ✓ Up to 85% preventative maintenance projected for 2025/26
- ✓ Accredited condition survey supplier, PAS 2161-ready
- ✓ Risk-based HAIP points system for planned resurfacing
- ✓ U-road RED share fell from 19.99% to 9.74% at last survey
Expect a documented Section 58 defence on well-maintained stretches. Generic claims will struggle.
What Works In Yours
- ✗ AMBER condition — one-third of A-roads in RED, only 16.46% green
- ✗ Council admits 10% rise in poor A-roads and 9% fall in good B/C roads
- ✗ 55.58% of U-roads in amber — sub-optimal on 264km of residential streets
- ✗ Boroughwide condition surveys only every two years
- ✗ 2,709 pothole repairs in five years — defects still forming reactively
- ✗ S81 notices tripled since 2019/20 — utility damage risk rising
The Winning Strategy Here Is Specificity
Against a council with GREEN spend scorecards and a risk-based asset programme, your claim lives or dies on the specific defect:
- • Prior reports of the same pothole (FixMyStreet, council reports) — proof of actual notice
- • Photos showing the defect's size, depth and visible age (weathered edges, previous patching)
- • The road's class — on an A-road, cite the 33.18% RED network rate; on a U-road, the biennial survey gap
- • Proximity to recent utility works or S81-enforced repairs
Mac builds exactly this case: he searches for prior reports, assesses your photo evidence, and cites Lambeth's own transparency data where it helps you.

Frequently Asked Questions
Lambeth projects £9.3m capital spend against a £585,000 DfT allocation — can I still claim?
Yes. The DfT Spend scorecard is GREEN, but your claim turns on the specific defect and road condition — and Lambeth is AMBER overall. Section 58 depends on whether the pothole that damaged your vehicle was reasonably inspected and repaired, not on aggregate spend. Lambeth's own report admits A-roads in RED condition rose 10% in five years while good-rated A-roads fell 19% since 2023.
What if my pothole was on a residential or unclassified road?
U-roads make up 264km — 75% of Lambeth's 354km network. At the last biennial survey in 2024, 9.74% were RED and 55.58% were AMBER, with only 34.66% green — a 12% decline in good-rated U-roads since 2020. Condition data is collected boroughwide only every two years, so ask when your street was last surveyed.
U-road RED fell from 20% to 10% — does that weaken my claim?
Not necessarily. The council attributes the shift partly to preventative micro-asphalt treatments on lower-trafficked roads, while A and B/C classified roads continue to decline. More than half of U-roads are now AMBER (sub-optimal), not green. A pothole claim still turns on the specific defect, prior reports, and whether a biennial survey regime was reasonable for that street.
Does the biennial condition survey gap affect Section 58?
It can. Lambeth collects condition data through a boroughwide survey every two years, and published figures repeat in alternate years — suggesting no fresh network-level data in between. For a defect forming between survey years, the council must still show its routine inspection regime was adequate. Prior reports and photos matter more when network condition data has a two-year lag.
S81 notices to utility companies hit 829 in 2024/25 — does that help my claim?
Potentially. Lambeth issued 829 Section 81 notices under NRSWA 1991 in 2024/25 — up from 324 in 2019/20 — compelling statutory undertakers to repair defective street apparatus. If your pothole sat near a recent utility excavation or damaged cover, third-party reinstatement failure may be relevant. The council still owes a duty under Section 41 of the Highways Act 1980 for the road surface itself.
