Dynamic Purchasing Systems

NHS trusts manage some of the largest and most complex estates in the public sector, with approximately 8,000 sites across England, alongside equivalent estates managed by health boards in Scotland, Wales, and Northern Ireland. Estate maintenance and statutory compliance work, covering electrical testing, gas servicing, fire safety, legionella management, and lift maintenance under the relevant estates guidance, such as HTM technical memoranda in England or SHTM guidance in Scotland, must be delivered continuously and without gaps. The challenge is that NHS procurement teams are under sustained resource pressure, and running standalone tenders for every compliance category and every site is not sustainable.

A DPS provides a pre-established compliant procurement route where supplier qualification has already been completed. When an NHS trust or health board needs to procure compliance services or estate maintenance, it issues a mini-competition to qualified suppliers in the relevant category rather than starting from scratch. Because the DPS stays open to new suppliers throughout its lifetime, the supply chain evolves as the market changes, which is particularly important in specialist compliance categories where contractor availability varies by region. In England, Wales, and Northern Ireland, the Procurement Act 2023 applies to all non-clinical NHS procurement (clinical services fall under the Provider Selection Regime); Scotland’s own procurement legislation applies to the equivalent non-clinical procurement carried out by NHS Scotland. All Inprova DPS solutions are fully compliant with the transparency, notice, and reporting requirements relevant to your nation. For trusts and health boards managing multiple compliance contracts across dispersed sites, Quantum provides the single view of contract performance, spend, and key dates that estates and facilities teams need to keep their compliance programme on track.

Yes, and for MATs specifically, the DPS model addresses a procurement challenge that frameworks don’t always solve. A multi-academy trust managing ten, twenty, or thirty school buildings needs to procure building works, compliance services, and improvement programmes at portfolio scale. But the regional spread of those schools often means the right contractor for one site isn’t available or competitive for another. A framework with a fixed supplier list doesn’t adapt to that reality.

A DPS stays open to new suppliers throughout its lifetime, which means the supply chain available for a competition in the North West isn’t limited to the same contractors who were appointed when the DPS launched three years ago. Regional specialists, local SMEs, and newer businesses can join as they meet the qualification criteria, giving MATs genuine choice in every geography. In England, the Procurement Act 2023 applies to all education institutions procuring above threshold, alongside the Academy Trust Handbook and DfE buying guidance; education bodies in Scotland, Wales, and Northern Ireland work to their own respective procurement legislation and estate guidance. All Inprova DPS solutions are designed to meet these overlapping compliance requirements so trust procurement leads and CFOs don’t need to interpret the legislation themselves. With England’s Education Estates Strategy committing £38 billion from 2025-26 to 2029-30 and new estate management reporting requirements arriving from autumn 2026, alongside similar capital investment programmes in the other UK nations, education providers need procurement routes that can mobilise quickly and evidence compliance. A DPS provides both.

A Dynamic Purchasing System and a Dynamic Market share the same core principle: both stay open to new suppliers throughout their lifetime. The key differences are in scope, flexibility, and legal framework. Under the previous procurement regulations, a DPS was restricted to commonly used, off-the-shelf purchases. Dynamic Markets, introduced by the Procurement Act 2023 in England, Wales, and Northern Ireland, remove that restriction entirely; Scotland continues to operate its own separate procurement legislation and does not currently have an equivalent Dynamic Market vehicle. They can be used for any type of goods, works, or services, including bespoke and complex requirements that wouldn’t have been eligible under a traditional DPS.

Dynamic Markets also simplify the supplier qualification process, give contracting authorities more flexibility in how they structure lots and set membership conditions, and provide a clearer legal framework that removes many of the ambiguities that surrounded DPS operation. Suppliers who become excludable under the Act’s mandatory or discretionary grounds can be removed from a Dynamic Market, which wasn’t straightforward under the DPS model. Inprova’s existing DPS solutions remain fully compliant and operational under the Act’s transitional provisions until they expire or until 23 February 2029, whichever comes first. New procurement routes are being established as Dynamic Markets from the outset. For buyers, the experience is familiar: the same open supplier access, the same electronic management, the same support from Inprova’s team. The legal framework behind it has simply been modernised.

The speed advantage of a DPS comes from the fact that supplier qualification has already been completed. In a standalone procurement, whether under the Procurement Act 2023 in England, Wales, and Northern Ireland, or Scotland’s own procurement legislation, the contracting authority must publish a tender notice, allow sufficient time for suppliers to respond, evaluate all submissions against published criteria, observe a standstill period, and then award the contract. For complex requirements, this can take several months from start to finish.

With a DPS, the qualification stage is already done. Suppliers on the system have been assessed for financial stability, technical capability, relevant experience, and health and safety credentials. When you need to procure, you issue a mini-competition to all qualified suppliers in the relevant category. Depending on the complexity of your requirement, contracts can be awarded in as little as two weeks. For organisations working to tight timescales, whether that’s an NHS trust or health board needing urgent compliance works, a school accessing time-limited capital funding, a council mobilising a programme against a fixed procurement window, or a blue light service responding to a governance recommendation from its national inspectorate, that speed difference is significant. Inprova manages the mini-competition process end to end, from developing your specification and evaluation criteria through to managing supplier responses and supporting the award decision.

The Building Safety Act 2022 introduced significant new obligations in England for organisations responsible for higher-risk and occupied buildings, including requirements around building safety cases, the appointment of accountable persons, mandatory occurrence reporting, and enhanced fire safety management; Scotland, Wales, and Northern Ireland each have their own building and fire safety legislation covering similar ground. For many public sector organisations, meeting these obligations requires procuring specialist contractors, surveyors, and consultants at pace and to a standard that satisfies the relevant regulator, the Building Safety Regulator in England, or the equivalent oversight elsewhere in the UK.

A DPS provides a compliant procurement route where suppliers have already been assessed for the specific accreditations and experience that building safety work demands. Because the supply chain stays open, specialist contractors who have developed building safety capabilities since the DPS launched can join and become available for competitions. This matters in a market where the pool of qualified professionals is still growing and the capabilities available today are broader than they were when most existing frameworks were tendered. For NHS and health bodies managing fire safety and building fabric across ageing hospital estates, education institutions addressing RAAC alongside broader building safety requirements, blue light services maintaining compliance in historic buildings, and local authorities managing mixed portfolios of building types with different risk profiles, the DPS provides access to the specialist supply chain that these requirements demand without the delay of a standalone procurement.

Decarbonisation is one of the fastest-moving procurement categories in the public sector. New heat pump technologies, insulation products, monitoring systems, and PAS 2035 qualified professionals are entering the market continuously. NHS and health bodies are working towards national net zero commitments, such as NHS England’s 2040 and 2045 targets, with Carbon Reduction Plan requirements expanding to all suppliers by April 2027. England’s Education Estates Strategy has committed £710 million for renewal and retrofit across the country’s schools and colleges, alongside similar investment programmes in the other UK nations. Local authorities are managing decarbonisation funding routes such as the Public Sector Decarbonisation Scheme in England or Scotland’s Public Sector Heat Decarbonisation Fund, alongside broader estate energy efficiency programmes.

A framework tendered two years ago cannot reflect the current state of the decarbonisation supply chain. The contractors and technologies available then may not be the best options available now. This is where a DPS has a structural advantage. Because new suppliers can join at any point, the supply chain keeps pace with the market rather than being frozen at the point of tender. PAS 2035 coordinators, retrofit assessors, heat pump installers, and monitoring technology providers who have entered the market or expanded their capabilities since the DPS launched can apply, be assessed, and become available for competitions. For public sector organisations delivering funded decarbonisation programmes with fixed spending deadlines, the DPS also provides the procurement speed needed to mobilise within tight timescales.

Yes, and this is common for larger or more complex programmes. Different elements of a project often lend themselves to different procurement routes. You might use a framework for materials supply where pricing is established and the market is stable, and a DPS for the installation works where you want access to an open supply chain and the flexibility to set your own specification and evaluation criteria for each competition. You might use a DPS for specialist compliance services while using a separate framework for general building maintenance.

Procurement legislation across the UK does not prevent contracting authorities from using multiple procurement routes within the same programme, provided each route is used compliantly for its intended scope. For NHS and health bodies managing large estate programmes that span compliance, construction, and decarbonisation, for multi-academy trusts and other education providers coordinating capital works across multiple sites, or for local authorities delivering improvement programmes that cover several building types and categories, using the right procurement route for each element is often more effective than trying to force everything through a single channel. Inprova’s team can help you map your programme requirements against the available procurement routes and identify the right combination for each element. There’s no additional cost for that advice, and it can save significant time by avoiding a procurement route that doesn’t fit the requirement.

Local Government Reorganisation is creating significant procurement complexity in parts of England, and councils elsewhere in the UK face similar disruption through their own boundary and function changes. When councils merge or restructure, existing contracts, supplier relationships, and procurement processes all need to transition to the successor authority. Running new standalone procurements during a period of structural change is particularly challenging because teams are stretched, priorities are competing, and there is uncertainty about future organisational structures and budgets.

A DPS provides continuity through this transition. Because a DPS is established as a compliant procurement vehicle available to all UK contracting authorities, any successor authority created through this kind of change can continue to use it without re-procurement. There’s no need to re-tender, no gap in supplier access, and no disruption to programmes that are already in delivery. For councils managing capital works, compliance programmes, and estate maintenance during a period of transition, this continuity is significant. The open supplier model also helps successor authorities that inherit a broader geographic area than their predecessors: new regional contractors can join the DPS as the authority’s estate expands, ensuring the supply chain reflects the new geography. Inprova’s team can support councils going through this kind of change with advice on how existing DPS contracts and procurement routes transfer to successor bodies under the procurement legislation relevant to your nation.

In England, Wales, and Northern Ireland, contracting authorities must have regard to the importance of maximising public benefit under the Procurement Act 2023 when carrying out procurements; in Scotland, the Procurement Reform (Scotland) Act 2014 places an equivalent sustainable procurement duty on public bodies. For UK central government, the social value model requires a minimum 10% weighting in most evaluations. For other public sector organisations, social value weighting is at the buyer’s discretion, but the expectation to include it is growing across every sector. Within a DPS mini-competition, you set your own evaluation criteria for each procurement, which means you control how social value is weighted and what you ask suppliers to commit to.

This flexibility is one of the practical advantages of a DPS over a framework where social value criteria were fixed at the point of tender. You can tailor your social value requirements to match the specific priorities of each project and your local area. A school in Warrington might prioritise apprenticeships and local employment. An NHS trust in London might prioritise air quality and carbon reduction. A council in a coastal town might prioritise investment in the local supply chain. Because each mini-competition is a standalone evaluation, you can ask different social value questions for different projects and weight them according to what matters most for that specific procurement. Inprova’s team supports you in developing social value evaluation criteria that are specific, measurable, and aligned to the public benefit requirements relevant to your nation. After award, Quantum tracks supplier social value commitments through the contract lifecycle, so promises made at tender are evidenced through delivery rather than forgotten once the contract is signed.

Yes, and this is one of the most common situations Inprova supports. Many public sector organisations, particularly individual schools, smaller multi-academy trusts, parish and town councils, smaller charities, and blue light services with limited back-office teams, don’t have dedicated procurement professionals. The assumption that a DPS is only accessible to organisations with large procurement teams is understandable but wrong.

Inprova’s DPS solutions are designed to be used with full support from our team. You don’t need to understand the procurement legislation, draft your own specification, or manage the tender process yourself. When you contact us with a requirement, our team works with you to define your scope of works, develop the specification and evaluation criteria, issue the competition to qualified suppliers, manage the responses, and support you through evaluation and award. After the contract is live, we provide ongoing contract management, performance monitoring, and advice on any issues that arise. For organisations without procurement resource, our team effectively acts as your procurement function for that project. For organisations with some procurement capability but limited capacity, we provide the specialist support and additional bandwidth that frees your team to focus on other priorities. There’s no minimum size requirement, no minimum contract value, and no expectation that you’ll manage the process independently. The DPS is the procurement vehicle. Inprova’s team is the support that makes it accessible regardless of your organisation’s size or resource.

Winning a contract through a DPS mini-competition is only part of the picture. The value of that contract depends on what happens over its lifetime: whether the supplier delivers to specification, whether pricing stays where it was agreed, and whether the social value and performance commitments made at tender actually materialise. For organisations managing multiple DPS contracts across dispersed building portfolios, tracking all of this manually through spreadsheets and supplier-generated reports is time-consuming and unreliable.

Quantum, Inprova’s spend and contract management platform, brings every DPS contract into a single secure view. You can track contract dates, documents, and obligations in one searchable register with automatic expiry and renewal alerts so nothing gets missed. Every transaction is recorded with line-level detail, so you can see exactly what’s been ordered, delivered, and charged across every contract. Pricing validation compares invoiced amounts against the rates submitted at mini-competition and flags discrepancies before they compound. KPI monitoring and social value tracking create a structured evidence base that you can present to boards, regulators, or auditors at any time.

For organisations managing DPS contracts alongside framework contracts and other procurement routes, Quantum consolidates everything into one platform rather than requiring separate tracking for each route. There’s no additional cost for Quantum access when you’re using Inprova’s procurement agreements. It’s included as part of the service. Find out more about how Quantum works on our technology page.

In England, Wales, and Northern Ireland, the Procurement Act 2023 introduced significantly expanded transparency obligations for public sector procurement. Contracting authorities must publish tender notices for every above-threshold procurement, contract award notices, contract details, and for contracts above £5 million, annual performance assessments including published KPIs. Pipeline notices giving advance visibility of planned procurements are also required. In Scotland, the Procurement Reform (Scotland) Act 2014 and Public Contracts (Scotland) Regulations 2015 carry their own transparency and reporting requirements. For procurement teams already managing heavy workloads, these additional requirements create a real administrative burden, wherever you’re based.

DPS solutions reduce that burden because much of the compliance infrastructure is built in from the start. The DPS itself has been established as a compliant procurement vehicle with full documentation and audit trails. When you run a mini-competition, the process is managed electronically through Inprova’s team, creating the notice history, evaluation records, and award documentation that the relevant legislation requires. You don’t need to build your own compliant procurement process from scratch for each competition.

After award, Quantum provides the structured data that ongoing reporting requirements demand. Contract performance, KPI tracking, spend data, and social value evidence are all captured in a single auditable platform. For organisations that need to publish annual performance assessments for contracts above £5 million, Quantum provides the evidence base without requiring manual data collation from multiple sources. For organisations managing multiple DPS contracts alongside other procurement routes, the platform consolidates everything into one view that supports both day-to-day contract management and the regulatory reporting relevant to your nation. Visit our tenders page for a full overview of these requirements and how they affect your procurement.

Yes, and this is one of the most practical questions our consultancy team helps organisations answer. The choice between a DPS and a framework isn’t always obvious. Both are compliant procurement routes. Both give you access to pre-assessed suppliers. But they suit different situations, and choosing the wrong one can mean paying for flexibility you don’t need or missing out on flexibility that would have delivered a better outcome.

As a general principle, frameworks work well for stable, well-defined categories where a fixed supplier list and pre-agreed pricing provide consistency and speed. A DPS works better where the market is evolving, where you want to set your own commercial terms for each procurement, where regional supplier availability matters, or where you need access to emerging specialist capability that wasn’t available when existing frameworks were tendered. But these are guidelines, not rules, and the right answer depends on the specific requirement, the delivery timeline, the contract value, and the funding conditions.

Inprova’s consultancy team brings deep category knowledge across building works, compliance, construction, decarbonisation, and professional services. They can assess your specific requirement and recommend the procurement route that gives you the best combination of speed, flexibility, compliance, and value. That advice is available whether you’re planning a single project or designing a procurement strategy for a multi-year capital programme. There’s no cost or commitment involved in that initial conversation. Explore our full consultancy services on our consultancy page.
