CPV 45-2 Construction works for buildings

About CPV 45-2

CPV 45-2 is the Common Procurement Vocabulary group covering works for complete or part construction of buildings, and civil engineering works associated with them. It sits inside division 45, construction works, and it is the largest group within that division by volume of UK public sector notices.

Where the wider division includes demolition, site preparation, installation, and completion trades, this group is the main building works itself: new build, extension, structural alteration, major refurbishment, and the associated substructure and envelope work. It is the code under which a school block, a housing scheme, a health centre, or a leisure facility is put out to market.

For contractors, this is the most competitive group in public procurement and also the most predictable. Public building programmes are announced, funded, and designed long before they reach this code, which means the pipeline is visible well in advance to anyone watching professional services appointments under CPV 71.

Active CPV 45-2 tenders

Live activity follows the public capital cycle closely. School condition and expansion programmes, social housing development and retrofit, health estate reconfiguration, and leisure and community facility renewal generate the bulk of it. Decarbonisation funding has added a substantial retrofit stream, which is procured under this code where the works are extensive enough to constitute major refurbishment.

Framework procurement has taken a very large share of this market. Rather than competing each scheme openly, many buyers appoint contractors to a multi-year framework and then run mini-competitions or direct allocations against it. That changes what a contractor must win: framework admission first, individual schemes second.

Housing retrofit and decarbonisation	Framework call-off	Council or registered provider
Health and community facilities	Framework or competitive procedure	NHS body or council
Major refurbishment and remodelling	Open procedure or framework	Any estate owner

Top buyers procuring CPV 45-2

Local authorities dominate this group, covering schools, housing, corporate estate, and leisure. Housing associations and registered providers form a large adjacent market with the same technical requirements and their own procurement consortia. In our own corpus Aberdeenshire Council, Moray Council, Newry Mourne and Down District Council, Kingdom Housing Association, Caerphilly County Borough Council, and Argyll and Bute Council are among the more frequent publishers under this group, reflecting both genuine building programmes and the granular notice publication practice on the Scottish, Welsh and Northern Irish portals.

Education buyers form a distinct segment: academy trusts and further education colleges procure independently of local authorities and often at a scale that suits regional contractors. NHS trusts procure building works through national and regional construction frameworks more often than through open competition.

Typical contract values under CPV 45-2

The median notice sits around a million pounds, which reflects the very large number of individual refurbishment, extension, and small new build schemes that make up the bulk of activity. The upper decile runs into the tens of millions, covering major new build programmes and multi-scheme frameworks.

Contractors should read the notice carefully to establish whether a value is a single scheme or a framework ceiling, because the two are routinely confused. A framework advertised at a large aggregate value across several years and multiple contractors distributes unevenly and offers no guaranteed volume. Individual call-offs from that framework are the real opportunity, and their size is often not published at framework stage.

Compliance and certifications for CPV 45-2 bidders

Safety scheme accreditation is the universal gate: CHAS, Constructionline, SafeContractor, SMAS, or an equivalent recognised scheme, and buyers generally accept these in place of their own health and safety questionnaire. ISO 9001, ISO 14001, and increasingly ISO 45001 certification are expected at the larger end.

Construction Design and Management Regulations 2015 duties are allocated in the contract and buyers will test how the principal contractor role is discharged. The Building Safety Act has introduced a competence and gateway regime for higher-risk buildings that changes both programme and evidence requirements, and buyers now ask for role-specific competence rather than general company capability. Social value is scored on effectively every competition in this group, commonly at ten per cent or more, with local employment, apprenticeships, and supply chain commitments the usual themes. Contractors should also expect scrutiny of payment practice, since public buyers check reporting on payment performance to subcontractors and poor figures can affect selection.

Frequently asked questions

How is CPV 45-2 different from CPV 45 generally?

Division 45 covers all construction works, including demolition, site preparation, installation trades, and completion work. Group 45-2 is specifically the construction of buildings and associated civil engineering. A contractor doing groundworks or site clearance is likely to see relevant notices under 45-1; one doing mechanical, electrical, or fit-out work under 45-3; and a main contractor building the structure itself under 45-2. Buyers do not always code precisely, so a main contractor should watch the division as well as the group.

Is it worth bidding for frameworks if there is no guaranteed work?

For most contractors working in this group, framework admission is now a precondition rather than an option, because a large share of public building work is allocated through them and is not otherwise advertised. The important discipline is assessing how the framework allocates: direct award by rotation, mini-competition, or buyer choice. Frameworks with many appointed contractors and no allocation mechanism are the weakest, and it is reasonable to decline them. Ask at clarification stage what the anticipated pipeline is and how many contractors will be appointed to each lot.

How much does social value actually affect the outcome?

Enough to decide close competitions. Weightings of ten per cent are common and some buyers go considerably higher, and because price and quality scores often cluster tightly among experienced contractors, the social value score is frequently the differentiator. The submissions that score well make specific, measurable, locally relevant commitments with a named person accountable for delivery, rather than restating national policy. Buyers increasingly monitor delivery against those commitments during the contract, so overcommitting at tender creates a real problem later.

What has changed for contractors under the Building Safety Act?

For higher-risk buildings, principally residential buildings above the height threshold, there is now a gateway regime that controls when work can start and when a building can be occupied, and a competence requirement attached to specific duty holder roles. Practically this means longer pre-construction programmes, more front-loaded design information, and a requirement to evidence individual and organisational competence for the roles the Act defines. It also introduces the golden thread obligation to maintain building information through the project, which affects handover requirements. Contractors working outside residential high-rise are less affected, but the general direction of buyer expectation on competence evidence has shifted across the group.
