Which tools help SMEs find subcontracting opportunities: UK highways maintenance
The free tools that find subcontracting work on UK government contracts, applied to highways: who holds each council's maintenance contract, and when it ends.

Skim award records for UK buyers: highways maintenance and road works (CPV 45230000, 45233000, 45233139, 45233140, 45233141, 50230000 and 50232000), contracts of £20m or more with a published end date between 1 April 2027 and 8 October 2036, framework agreements excluded, together with title searches of award and planning notices and each prime's own Skim supplier record. Snapshot 8 October 2026. Counts are distinct contracts after merging notices published twice, and are floors: contracts below £20m, contracts with no published end date and contracts coded under unrelated categories are missed. End dates are as published and are approximate; where two notices for one contract disagree, the later date is shown and the difference noted. Company groups are merged only where the trading name on the notice shows it. Contract values are not quoted, with one exception, because most of these notices come from sources that publish no framework flag, so a published figure may be a whole-term estimate or a ceiling rather than a contract value.
The short answer

Skim award records, snapshot 8 October 2026
The most useful free tool for finding subcontracting opportunities on UK government contracts is the award notice, because it names the prime contractor that holds the work, which is the firm a subcontractor needs to approach. In UK highways maintenance those primes hold council contracts that run from about five years (Islington's, 2022 to 2027) to more than twenty (Kent's, awarded in 2025 and due to end in January 2047). So the question an SME needs answered is not which tenders are open this week, but who holds the highways contract in each area it can serve, and when that contract comes up again.
Every notice used here is public on Contracts Finder or Find a Tender. On the 8 October 2026 snapshot, Skim's records show eight primes each holding two or more live highways maintenance contracts across England, and at least three councils, Shropshire, Islington and Haringey, already preparing the next contract while the current holder is still in place.
The free tools, and how to use them
All of this can be rebuilt from public notices at no cost. The tools are the government's own portals plus the primes' supplier registrations.
| Tool | Cost | What it gives a subcontractor |
|---|---|---|
| Contracts Finder | Free | Award notices naming the main contractor, and some subcontract opportunities that primes choose to publish there |
| Find a Tender | Free | Higher-value awards, and planning notices for the next contract, such as the one Shropshire Council published on 15 September 2026 |
| Public Contracts Scotland, Sell2Wales and eTendersNI | Free | The same notices for the devolved nations |
| The prime's own supplier registration | Free | The prime's own route for suppliers to put themselves forward; requirements differ by prime, so check each one, and registering does not guarantee work |
| Award-data platforms, Skim among them | Paid | The same notices grouped by contractor, buyer and end date, which saves the export but adds no record the notices do not hold |
Search by title words as well as by category code. Kent's highway term maintenance notice on Find a Tender is coded under vehicle categories rather than road maintenance, so a category filter misses the largest contract in this map; its Contracts Finder copy is coded correctly. Searching titles for "highway term maintenance", "highways term maintenance", "highway services" and "term service" catches what the codes miss.
Then read the end date on each award, and look for a planning notice from the same council. A planning notice for a new contract, published while the old one still runs, is the clearest public sign that the prime may change and that bidders will soon be assembling their supply chains.
The partner map
The primes holding two or more live highways maintenance contracts on Skim's records, with the bodies they hold them for and the last end date. Contracts held jointly with a second firm are shown separately. Counts are floors.
| Prime contractor | Live contracts on record | Held for | Last one ends |
|---|---|---|---|
| Kier (Kier Highways, Kier Transportation) | at least 6 | National Highways Areas 3 and 4; Shropshire; Birmingham, on an interim contract; Transport for London road tunnels; West and North Northamptonshire | September 2036 |
| Marlborough Highways | 5, and 1 shared | Islington; Haringey; Greenwich; Havering; Southend; Newham, with Kenson Highways | February 2033 |
| Tarmac | 4, and 1 shared | Walsall; Halton and Warrington; Leicestershire surfacing; South Gloucestershire surfacing; Knowsley, with AECOM | June 2031 |
| Ringway | 4 | Kent; Hertfordshire; Milton Keynes; National Highways East region | January 2047 |
| Milestone Infrastructure | 3 | Oxfordshire; Wiltshire; Central Bedfordshire | March 2033 |
| Balfour Beatty (Living Places, Civil Engineering) | 2, and 1 shared | Buckinghamshire; Southampton; East Sussex, with WSP | December 2035 |
| FM Conway | 2 | Lewisham; Bromley | June 2032 |
| VolkerHighways | 2 | Street lighting for Kingston upon Thames and Somerset | May 2036 |
Three patterns stand out. The National Highways maintenance contracts on record sit with four primes: Kier holds Areas 3 and 4, Colas Area 9, Amey Area 7 and Ringway the East region. London boroughs lean on mid-sized highways contractors rather than national primes: Marlborough Highways holds four London borough contracts and shares a fifth, as well as Southend's, and FM Conway holds two. And the newest county contracts are the longest: Hertfordshire's and Kent's, both awarded to Ringway in 2025, run to 2046 and 2047.
Named contracts to open a conversation with
One live contract per prime, each with years left to run. A named contract with its end date gives a prime's supply-chain team a specific reason to take the call.
| Prime contractor | Contract | Awarding body | Ends |
|---|---|---|---|
| Ringway | Highway Term Maintenance Contract 2026 | Kent County Council | 28 January 2047 |
| Kier | Highway Services, for West and North Northamptonshire | West Northamptonshire Council | 4 September 2036 |
| Balfour Beatty Living Places | Buckinghamshire Highways Term Maintenance Services Contract | Buckinghamshire Council | 31 March 2035 |
| Milestone Infrastructure | Highway Maintenance Contract | Oxfordshire County Council | 6 February 2033 |
| Marlborough Highways | Infrastructure Maintenance and Improvements | Southend City Council | 21 February 2033 |
| FM Conway | Highways Maintenance | London Borough of Bromley | 30 June 2032 |
| Amey | Area 7 Maintenance and Response Contract | National Highways (published as the Highways Agency) | 30 June 2031 |
| Colas | Area 9 Maintenance and Response Contract, West Midlands | National Highways (published as Highways England) | 30 June 2030 |
| Tarmac | Highways Term Maintenance Contracts | Halton and Warrington borough councils | 31 May 2029 |
Kent's notice publishes a value of £2bn over the contract's term. It is the only value quoted in this report, because it is recorded as a contract value; most of the other notices come from sources that do not say whether a published figure is a contract value or a ceiling.
Where the prime may change next
A new highways contract often means a new or re-formed supply chain, and the firms bidding for it look for subcontractors before they submit. Five contracts on record end by 2029 at councils that have already published something about what comes next.
| Contract | Current holder | Current contract ends | Published so far |
|---|---|---|---|
| Islington Term Service Highway Works | Marlborough Highways | 26 May 2027 | Planning notice for a Highways Term Service Works Contract, 9 April 2026 |
| Haringey Highway Maintenance and Minor Improvement Works | Marlborough Highways | 30 June 2027 | Planning notice for a Highways and Street Lighting Contract, 17 May 2026 |
| Cambridgeshire Highway Services | Skanska UK | 30 June 2027 | Legal support appointed for the council's highways programme, two awards in 2025 |
| Shropshire Highways Term Maintenance | Kier Highways | 31 March 2028 | Planning notice for a new Highways Term Maintenance contract, 15 September 2026 |
| Walsall Highways and Infrastructure Services | Tarmac | 31 March 2029 | Legal support appointed for a Highways Term Maintenance Contract 2029, August 2026 |
Devon County Council also published a planning notice for a new highways term maintenance contract in May 2025. Birmingham's current highways services contract, awarded to Kier in July 2026 and running to July 2028, is titled interim. Neither notice says who will bid.
What this means for an SME subcontractor
A highways term maintenance contract covers a council's routine and reactive road work for years at a time, and the holder delivers part of it through its own supply chain. For an SME, that makes the map above a list of the firms to approach in each area: register with the prime that holds the contract where you work, and quote the contract by name when you make contact.
Timing matters as much as the name. The months before a recompete, when bidders assemble their teams, and the months after a new contract starts, when the winner mobilises, are when supply chains are most open. On this record, Islington, Haringey and Cambridgeshire reach that point in 2027, Shropshire in 2028 and Walsall in 2029.
Not every council puts everything through one prime. Somerset and Wiltshire let surfacing or surface dressing as separate contracts alongside their main highways contract, Leicestershire lets machine-laid surfacing and patching separately, and Kent let a Local Highway Maintenance Support Contract to four firms in March 2026. Those lots are tendered on the same portals.
What this data cannot tell you
It shows who holds the contracts, not whom they buy from. Subcontract awards are almost never published, so the data cannot say which SMEs are already in a prime's supply chain, or what share of the work a prime lets out.
Every count is a floor. The search covers contracts of £20m or more with a published end date and a highways category code. Contracts below that size, with no end date, or coded under unrelated categories, as Kent's Find a Tender notice is, are missed unless a title search or the prime's own record caught them. Gloucestershire's highways term maintenance contract, awarded to Ringway in 2019, and West Berkshire's, held by Marlborough Highways, surfaced without an end date and are not counted.
The public record disagrees with itself in places. Central Bedfordshire, Wiltshire, Havering, Herefordshire and Milton Keynes each published their highways contract twice with two different end dates, and Wiltshire, Herefordshire and Milton Keynes with two different values. Northamptonshire's highway services contract appears under three notices carrying three different values. Each is counted once here.
FAQ
Which tools help SMEs find subcontracting opportunities on UK government contracts?
The free ones are Contracts Finder and Find a Tender, plus Public Contracts Scotland, Sell2Wales and eTendersNI in the devolved nations. Their award notices name the prime contractor holding each contract, and Contracts Finder also carries some subcontract opportunities that primes publish. Each prime's own supplier registration is the usual way to put a firm forward, though what it asks for, and what it leads to, differs by prime. Award-data platforms, Skim among them, group the notices by contractor and end date for a fee.
How do I find a prime contractor to partner with on UK highways work?
Search award notices for the councils you can serve, using title words such as "highway term maintenance" as well as road maintenance category codes. Each notice names the contractor holding that council's highways contract and when it ends. Register on that contractor's supplier portal and quote the contract by name.
How long do council highways maintenance contracts last?
On Skim's records they run from about five years to more than twenty. Islington's runs from 2022 to May 2027; Kent's, awarded to Ringway in 2025, runs to January 2047, and Hertfordshire's, also awarded to Ringway in 2025, to September 2046.
When is the best time to approach a highways prime about subcontracting?
Before a recompete, when bidders are building their teams, and soon after a new contract starts, when the winner is mobilising. A council's planning notice for its next contract is the public signal: Islington, Haringey and Shropshire have each published one while the current contract still runs.
