Milton Keynes: one in four estate roads now RED
Milton Keynes earns GREEN on spend — projected capital investment nearly doubles its DfT allocation — yet the overall rating is AMBER because 26% of unclassified roads are in RED condition, up from just 5.3% in 2020/21. On the famous grid network, green-condition B and C roads fell to 77.0% in 2024/25 as a contract change paused preventative work and halved pothole repairs.
What the condition data shows
Five years of SCANNER and CVI survey data from Milton Keynes City Council's own DfT transparency report — main roads slipped in 2024/25, estate roads in sustained decline
A-roads (118km — 8% of network): sharp 2024/25 reversal
A-roads including routes like Monks Way (H3 — the A422) are surveyed in full every year. The council notes SCANNER surveys were paused and carried out out of season in 2024/25, when the network is naturally in poorer condition — which it says negatively affected classified-road results.
B and C roads — including most grid roads (315km — 21% of network): slipping
| Year | Red | Amber | Green |
|---|---|---|---|
| 2020/21 | 1.1% | 14.3% | 84.6% |
| 2021/22 | 1.8% | 16.2% | 82.0% |
| 2022/23 | 1.9% | 16.0% | 82.1% |
| 2023/24 | 1.9% | 14.7% | 83.4% |
| 2024/25 | 2.9% | 20.1% | 77.0% |
Grid roads and other B and C routes lost six percentage points of green-condition share in a single year. Nearly one in four kilometres on this network now needs — or will soon need — maintenance.
The DfT scorecards — GREEN spend, AMBER everywhere else
The government rates Milton Keynes' investment as strong — projected 2025/26 capital spend of £21.1m against a DfT allocation of £10.7m — but condition remains AMBER because the road surface data tells a different story.
The 1,060km estate road problem
71% of Milton Keynes' carriageway network is unclassified — surveyed on a rolling 25% sample each year
| Year | U-roads in RED condition |
|---|---|
| 2020/21 | 5.3% |
| 2021/22 | 7.6% |
| 2022/23 | 20.9% |
| 2023/24 | 26.0% |
| 2024/25 | 26.0% |
The four-year CVI cycle
Milton Keynes surveys 25% of unclassified roads each year using Coarse Visual Inspection. The overall condition figure is totalled over the four-year survey period — so any given estate street may go several years between condition assessments.
The council also notes U-road condition fluctuates on a five-year surface-treatment cycle, with additional funding applied specifically for preventative treatments. Even so, RED share has risen fivefold since 2020/21 and has plateaued at 26% for two consecutive years.
What 26% means in kilometres
At 26% RED on 1,060km of unclassified roads, roughly 276km of estate streets, cul-de-sacs and rural lanes sit in the category the council uses for roads that should be considered for maintenance in the next cycle.
A RED section is not necessarily an immediate safety defect — those are picked up by regular safety inspections — but it is a section the council's own survey data flags for treatment.
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 Milton Keynes' unclassified network, ask:
- • When was your road last included in the 25% CVI sample — and what did it show?
- • If 26% of U-roads are RED at the last published survey, what was done about yours?
- • How does a four-year rolling total capture deterioration on a road surveyed only once in that window?
- • Did the 2024/25 contract transition reduce routine repairs on your route to safety-critical only?
A council cannot claim detailed knowledge of a network it samples incrementally — while publicly acknowledging that condition dropped during a service disruption.
Grid roads, roundabouts and the £90m junction programme
Milton Keynes' distinctive H-road grid includes most B and C carriageways — and some of its busiest roundabouts
“We are investing up to £90m into improving key junctions on the grid road network so Milton Keynes can handle future traffic levels. We have identified several roundabouts where we need to make some improvements now to increase capacity and reduce congestion ahead of the growth expected up to 2045.”
— Milton Keynes City Council — Highways Maintenance Interim Report for the DfT, June 2025
| Priority junction | Location |
|---|---|
| Monkston roundabout | A421 and H7 Chaffron Way — first to be improved |
| Brinklow roundabout | A421 and H7 Chaffron Way — first to be improved |
| Crownhill | Tariff-funded scheme under assessment |
| Elfield Park | Tariff-funded scheme under assessment |
| Loughton | Tariff-funded scheme under assessment |
| Kingston | Tariff-funded scheme under assessment |
Deferred works, continuing deterioration
The council states several grid road sections scheduled for major junction upgrades were originally planned for 2024/25 but paused to coincide with the new highways contract. Those sections “continued to deteriorate and only received minor repairs” until work commenced on the £90m programme — to be delivered by 2030, funded by developer tariffs.
Planned improvements include lane widening, enlarged roundabouts, signalisation and enhanced road markings — with innovation through artificial intelligence cited in the report.
Questions worth asking
- • Was your incident on a grid approach where junction upgrades were deferred?
- • Did the council increase inspection frequency on routes it knew were deteriorating?
- • If only safety-critical repairs were carried out in 2024/25, why wasn't your defect caught?
- • Was the pothole on a Redway (341km of cycle paths) or footway (925km) rather than a carriageway?
97,708 equivalent potholes in five years
Milton Keynes measures repairs by surface area, not individual potholes — then converts to an equivalent count
| Year | Surface area repaired (m²) | Equivalent potholes |
|---|---|---|
| 2020/21 | 5,434 | 21,736 |
| 2021/22 | 4,695 | 18,780 |
| 2022/23 | 4,836 | 19,344 |
| 2023/24 | 6,550 | 26,200 |
| 2024/25 | 2,912 | 11,648 |
| Five-year total | 24,427 | 97,708 |
The equivalent-pothole calculation
Milton Keynes defines a pothole as at least 30cm across. Each repair allows 10cm either side, so the minimum patch is 50cm × 50cm (0.25m²). Every square metre repaired equals four equivalent potholes — the basis for the table above.
The council states that in an average year it will repair the equivalent of around 19,500 potholes — roughly 53 per day across the 1,493km road network.
Why 2024/25 halved
The council explains 2024/25 was a transitional year during procurement of a new long-term maintenance contract. Normal operational planning was interrupted, planned surface treatments were deferred to 2025/26, and routine road repairs were reduced to safety-critical work only.
That is not evidence the network improved — it is evidence fewer defects were treated while condition data was simultaneously worsening.
“2024/25 was a transitional year as we began a new long-term maintenance contract. The process was both extensive and complex, including awarding the contract, 'demobilising' the existing arrangements, and mobilising the new contract during the service year. As a result the normal operational planning and delivery of services was interrupted.”

GREEN spend on a £7.1bn network
Milton Keynes describes its highway network as the city's most valuable asset — and invests accordingly
| Year | DfT allocation | Capital spend | Revenue spend | Preventative | Reactive |
|---|---|---|---|---|---|
| 2020/21 | £9.3m | £14.1m | £5.3m | 77% | 13% |
| 2021/22 | £7.9m | £11.8m | £6.6m | 70% | 16% |
| 2022/23 | £7.9m | £11.7m | £9.0m | 63% | 20% |
| 2023/24 | £9.9m | £17.8m | £8.6m | 72% | 15% |
| 2024/25 | £8.7m | £12.3m | £8.7m | 65% | 19% |
| 2025/26* | £10.7m | £21.1m | £7.4m | 77% | 9% |
* projected spend
Investment without recovery — yet
Over five years Milton Keynes fully resurfaced 28km (just under 2% of the network) and applied surface treatments to a further 53km (around 3.5%). The council adopted prudential borrowing to fund larger preventative programmes — yet U-road RED condition still quintupled and 2024/25 brought the steepest classified-road decline in the published data.
GREEN spend scorecards measure whether a council invests adequately. They do not mean every road — or every pothole — was reasonably maintained when your incident occurred.
Claiming against a GREEN-spend, AMBER-condition council
Honest assessment: Milton Keynes invests seriously — here is how that shapes your approach
What works in the council's favour
- ✓ GREEN spend — projected capital nearly double the DfT allocation
- ✓ Documented asset management strategy and AMX system
- ✓ Monthly safety inspections on major routes; every reported pothole inspected
- ✓ 77% of 2025/26 budget projected as preventative maintenance
- ✓ New Ringway contract with extended quality guarantees from September 2024
Expect a structured Section 58 defence on well-maintained grid routes with recent inspection records.
What works in yours
- ✗ AMBER condition — 26% of U-roads RED, grid roads slipping in 2024/25
- ✗ Only 25% of U-roads CVI-surveyed each year on a four-year rolling total
- ✗ 97,708 equivalent pothole repairs in five years — defects form between inspections
- ✗ Admitted service disruption and deferred treatments during contract change
- ✗ Junction upgrades deferred while grid sections “continued to deteriorate”
The winning strategy here is specificity
Against a council with GREEN spend scorecards, your claim lives or dies on the specific defect:
- • Prior reports of the same pothole (FixMyStreet, Report It) — proof of actual notice
- • Photos showing the defect's size, depth and visible age (weathered edges, previous patching)
- • The road class — on a U-road, the 25% CVI sample and four-year cycle is your strongest structural argument
- • Location on the grid network — especially if junction upgrades were deferred in 2024/25
- • Timing — incidents during the contract transition when only safety-critical repairs were made
Mac builds exactly this case: he searches for prior reports, assesses your photo evidence, and cites Milton Keynes' own transparency data where it helps you.
Report the pothole to Milton Keynes first
Milton Keynes City Council states it inspects every pothole reported and carries out monthly safety inspections on major routes and grid roads.

Frequently asked questions
Milton Keynes earns GREEN on spend — can I still claim?
Yes. The DfT Spend scorecard is GREEN because projected 2025/26 capital spend of £21.1m exceeds the £10.7m DfT allocation. But the overall and condition ratings are AMBER. Section 58 turns on whether the specific defect that damaged your vehicle was reasonably inspected and repaired — not on aggregate spend.
What if my pothole was on a grid road or roundabout?
Most grid roads are B and C roads — 315km of the network. In 2024/25, green-condition share fell from 83.4% to 77.0%. The council is investing up to £90m in junction upgrades including Monkston, Brinklow, Crownhill and Loughton roundabouts. If your incident was on a deferred junction approach, that context is relevant to whether inspection intervals were reasonable.
What if my pothole was on an estate or rural unclassified road?
Unclassified roads make up 1,060km — 71% of the network. RED condition rose from 5.3% in 2020/21 to 26.0% in 2023/24 and 2024/25. The council surveys only 25% of U-roads each year, with condition totalled over a four-year cycle.
Pothole repairs halved in 2024/25 — does that mean the roads are fixed?
No. The equivalent of 11,648 potholes were repaired in 2024/25 — down from 26,200 in 2023/24. Milton Keynes explains this as a transitional year during procurement of a new highways contract, when routine repairs were reduced to safety-critical work only. The council still expects around 19,500 equivalent repairs in an average year.
Does the contract transition admission help my claim?
Potentially, especially for 2024/25 incidents. The council states overall condition dropped and was “largely linked to the procurement of a new highways contract”, with SCANNER surveys carried out out of season and planned surface treatments deferred. That documents interrupted maintenance — relevant when assessing whether the council had a reasonable system for your road.
How do I report a pothole to Milton Keynes City Council?
Use the Report It section at milton-keynes.gov.uk or the dedicated potholes page. Provide the street name, postcode and photos. For emergencies call 01908 252353 (office hours) or 01908 226699 out of hours. Reporting creates a dated council record useful if the defect was known before your incident.
Does the £90m grid junction programme affect my claim?
It provides context. The council acknowledges grid sections continued to deteriorate when junction upgrades planned for 2024/25 were paused. Work has now commenced on the £90m tariff-funded programme to be delivered by 2030. If your incident was on a deferred approach, that strengthens arguments about reasonable inspection and repair.
