Framework agreements have become one of the most common ways for construction clients in the UK to organise ongoing work across multiple projects. Rather than running a fresh tender every time a building, refurbishment or civils package is needed, the client sets up a pre-agreed arrangement with one or more suppliers and calls off work as and when required.
This saves procurement time, builds familiarity between the parties and gives contractors a degree of pipeline visibility. I'm Brad Askew, and in this guide I'll walk through how framework agreements work in the construction sector, the commercial and legal mechanics that sit behind them, and the points that tend to cause friction if they aren't thought through at the outset.
Whether you're a client considering putting a framework in place or a contractor being invited onto one, the principles below should give you a clear starting point.
What this document is
A framework agreement in construction is an umbrella arrangement between a client (often a public body, housing association, developer or large private estate owner) and one or more appointed suppliers, setting out the terms on which future work can be ordered. The framework itself usually does not guarantee any actual work.
Instead, it establishes the rules of engagement: who is eligible to be invited, how individual contracts (known as call-offs) will be awarded, what pricing basis applies, the standard form of contract to be used for each call-off, the quality and performance expectations, and how long the arrangement will run. When a specific project arises, the client either awards it directly to a framework supplier under pre-set terms or runs a mini-competition between the appointed suppliers.
Each call-off then becomes a standalone contract in its own right. Frameworks are heavily used across the UK public sector, including local authorities, the NHS, education bodies and central government, and they are increasingly common in the private sector too for repeat-buyer clients.
How to use this document
01
Define the scope and duration. Decide what categories of work the framework will cover, the geographical area, the anticipated value, and how long it will run. Public sector frameworks are typically capped at around four years unless a longer term can be properly justified, so think carefully about pipeline before committing.
02
Choose single-supplier or multi-supplier structure. A single-supplier framework offers simplicity and deeper partnering but less price tension. A multi-supplier framework with several appointed contractors creates competitive pressure through mini-competitions but takes more effort to administer. Pick the model that matches your project pipeline and internal resource.
03
Run a compliant appointment process. For public bodies, the appointment must follow the applicable procurement rules, with clear selection criteria, award criteria and a transparent evaluation trail. Private clients have more flexibility but should still document how suppliers were chosen to avoid disputes later if a bidder feels unfairly treated.
04
Agree the call-off mechanism and pricing basis. Spell out exactly how individual orders are awarded, whether through direct award, mini-competition or a rotation. Set out the pricing approach (schedule of rates, target cost, lump sum against a pricing document, or open-book) and how it will be indexed or reviewed over the life of the framework.
05
Build in performance management and exit terms. Include KPIs, review meetings, a route for poor performers to be removed, and clear provisions for termination, suspension and dispute resolution. Think about what happens at the end of the term, particularly for call-offs that run beyond framework expiry.
Common questions
QDoes a framework agreement guarantee the contractor any work?
In almost all cases, no. The framework sets the terms on which work can be ordered but does not commit the client to placing any minimum volume. Contractors should read the recitals and scope clauses carefully, because some frameworks include indicative volumes that are expressly non-binding. If you need guaranteed turnover to justify resourcing the framework, that needs to be negotiated separately.
QWhat is the difference between a framework agreement and a call-off contract?
The framework agreement is the overarching arrangement setting out the rules, rates and standard terms. A call-off contract is the actual contract for a specific piece of work, formed when the client places an order under the framework. Each call-off is legally a separate contract, usually based on a standard form such as JCT or NEC with framework-specific amendments.
QHow long can a construction framework agreement run?
Under UK public procurement rules, framework agreements are generally limited to around four years unless there are exceptional circumstances that justify a longer term. Private sector frameworks can run for any period the parties agree, though very long terms without review mechanisms tend to cause problems as market conditions, costs and specifications change over time.
QWhat standard form contracts are used for call-offs?
The most common choices are JCT (particularly the Measured Term Contract or Minor Works forms for smaller packages) and NEC (with the NEC4 Framework Contract sitting above an Engineering and Construction Contract or Short Contract at call-off level). The framework should specify which form applies and list the standard amendments, so parties aren't renegotiating the contract every time a new project is ordered.
QCan a framework be used by organisations other than the original client?
Only if the framework was set up that way. Some public sector frameworks are deliberately structured as multi-user or central purchasing frameworks, allowing a defined list of contracting authorities to call off work. Any permitted users must be clearly identified when the framework is advertised. You cannot simply bolt additional buyers on later without risking a challenge.
QHow is pricing kept fair over a multi-year framework?
Most frameworks include an indexation or price adjustment mechanism tied to a recognised index such as BCIS or CPI, applied at set review points. Others use open-book pricing where costs are transparent and a pre-agreed margin applies. The key is to set the mechanism out clearly at the start, because ad-hoc price changes during the framework are a common source of dispute.
QWhat happens to live call-offs if the framework expires or is terminated?
A well-drafted framework will confirm that call-offs entered into before expiry continue under their own terms until completion, even after the overarching framework ends. If this isn't spelled out, there can be arguments about which provisions still apply. Termination for convenience and for breach should also be dealt with separately at framework level and at call-off level.
