CPV 90 Sewage and refuse services

About CPV 90

CPV 90 is the Common Procurement Vocabulary division covering sewage services, refuse and waste services, cleaning and sanitation services, and environmental services. In practice it is the municipal services division: the work that councils are statutorily obliged to provide and that therefore never stops being procured.

The division covers household and commercial waste collection, recycling collection and processing, residual waste treatment and disposal, street cleansing, gully and drainage maintenance, grounds and environmental cleaning, hazardous and clinical waste, contaminated land remediation, and environmental monitoring and consultancy.

Two things distinguish it from other service divisions. The first is contract scale and duration: residual waste treatment contracts routinely run for twenty years or more because they underwrite the financing of treatment infrastructure, making them among the longest contracts in public procurement. The second is that the statutory duty behind most of the work insulates it from budget cycles. A council under severe financial pressure can defer a capital scheme; it cannot stop collecting bins.

Live activity is driven by three overlapping cycles. Collection contracts come round on seven to ten year terms and are the highest-volume opportunity. Treatment and disposal arrangements move much more slowly but at far greater value. Environmental consultancy, remediation, and monitoring generate a continuous flow of smaller commissions attached to development and regulatory work.

Policy is currently a significant driver of new procurement. Consistency requirements for household recycling collections, the deposit return scheme, and extended producer responsibility have all pushed councils into reviewing collection arrangements, fleet, and container provision, generating procurement that would not otherwise have occurred on the normal cycle.

Residual waste treatment and disposal	Very long-term, project financed	Waste disposal authority
Street cleansing and grounds cleaning	Bundled with collection or separate	District or unitary council
Clinical and hazardous waste	Framework call-off	NHS body or council
Environmental consultancy and remediation	Below-threshold or framework	Council, agency, developer

Top buyers procuring CPV 90

Local authorities dominate, but the structure matters: in two-tier areas, district councils are the waste collection authorities and county councils are the waste disposal authorities, so collection and disposal are procured by different bodies on different cycles. Unitary authorities hold both functions and can therefore let integrated contracts, which changes the shape of the opportunity considerably.

Beyond councils, the buyer base includes the environmental regulators and conservation bodies, which in our own corpus publish under this code unusually often. NatureScot, Natural England, and the Joint Nature Conservation Committee appear frequently, reflecting environmental monitoring and land management work rather than waste collection. NHS bodies procure clinical waste separately under specialist arrangements, and water companies procure sewerage and sludge services under the utilities rules.

Typical contract values under CPV 90

The median notice sits in the mid hundreds of thousands of pounds, which reflects the substantial volume of smaller environmental and cleansing commissions. That median badly understates the character of the division, because the value is heavily concentrated at the top.

Integrated collection and cleansing contracts for a mid-sized council typically run in the low tens of millions across their full term. Residual waste treatment contracts, particularly those underwriting energy-from-waste or mechanical biological treatment facilities, run into the hundreds of millions across twenty to twenty-five years and are procured through competitive dialogue with a small field of bidders capable of raising the finance. Suppliers should be realistic about which tier they are competing in, because the qualification requirements at the top end effectively exclude all but a handful of national and international operators.

Compliance and certifications for CPV 90 bidders

Environmental permitting is the central requirement. Waste carriers, brokers, and dealers must be registered with the relevant environment agency, and operators of treatment or transfer facilities require environmental permits specific to the activity and site. Buyers verify these directly rather than accepting self-declaration, and they check that the permit covers the exact waste codes in scope.

Beyond permitting, operator licensing for the vehicle fleet is required through the traffic commissioner, with transport manager qualification. Safety accreditation through CHAS, SafeContractor, or an equivalent scheme is standard, as is ISO 14001 environmental management certification at the larger end. Duty of care documentation and waste transfer note handling are examined closely because the buyer retains legal responsibility for its waste. Clinical waste carries additional consignment note requirements and specific treatment standards. TUPE is almost always in play on collection recompetitions, and the incoming supplier inherits a large operational workforce, so employment cost modelling is a decisive part of pricing.

Frequently asked questions

Why are waste contracts so much longer than other public contracts?

Because many of them underwrite infrastructure. A treatment facility costs a great deal to build and can only be financed against a guaranteed long-term waste supply, so the contract term matches the financing period rather than the usual procurement cycle. Collection contracts are shorter but still long by public sector standards, because the incoming supplier must buy a fleet and containers, and those assets need a long enough term to depreciate against. The practical consequence for suppliers is that these opportunities are rare and decisive: losing one can mean waiting the better part of a decade for another chance in that geography.

Is there a realistic route in for a smaller operator?

Yes, though not usually through headline collection contracts. Street cleansing, grounds-related environmental work, gully cleansing, bulky waste, and commercial waste collection are frequently let separately and at a scale a regional operator can serve. Environmental consultancy, monitoring, and remediation are effectively a separate market inside the same code with no fleet requirement at all. Subcontracting to a major operator for specific streams, particularly hazardous and specialist waste, is another established route.

How have the recent recycling reforms changed procurement?

They have brought a wave of contracts to market earlier than the normal cycle would have done. Requirements for greater consistency in what is collected from households have forced many councils to reconsider container provision, vehicle specification, and collection frequency, and those changes are often large enough to require a variation or a recompetition. Extended producer responsibility has also changed the financial model behind collection, which affects how councils structure risk and payment in new contracts. Suppliers should expect specifications that are less settled than they were, and should read the change control provisions carefully, because further policy movement during a long contract term is likely.

Who actually buys my service in a two-tier area?

It depends on what you do. If you collect waste from households, the buyer is the district or borough council as waste collection authority. If you treat or dispose of it, the buyer is the county council as waste disposal authority, or a joint waste authority where one exists. Street cleansing sits with the collection authority. Getting this wrong wastes considerable business development effort, and it is worth confirming the local structure before approaching anyone, because joint arrangements and partnerships vary from county to county.
