The public sector spent £434 billion in 2024/25 across the UK and represents £1 in every £3 of government spending. This is achieved across various types of commissioning bodies who procure a wide range of goods and services from health and social care, education, housing, employment support and justice services, through to technology, facilities management, construction, consultancy, transport and professional services.
As a potential supplier, understanding the differences between buyers can make a huge impact to successful bid strategy as different buyers have different portals, priorities and even evaluation methods and criteria. For example, you cannot expect a local authority (Council) to approach procurement and contract awards using the exact same methodology as the NHS, Ministry of Defence, Department for Work and Pensions, or Crown Commercial Service.
At the Evolve Network Group we have created this guide as an introduction to the various types of UK public sector buyers and commissioning bodies you need to be aware of when bidding for public sector work. We also work to include the types of services commonly procured by each type of buyer which you can use to develop your own bid strategy for the future.
Crown Commercial Service (CCS)
The Crown Commercial Service is a major UK public sector buying organisation acting as an Executive Agency and Trading Fund of the government’s Cabinet Office. It does not operate like a single commissioner (buying only for itself) and instead manages commercial agreements and frameworks that public sector organisations can use to buy common goods and services totalling c.£33billion+ annually.
Suppliers may encounter CCS when applying for framework agreements covering areas such as technology, facilities management, professional services, workforce, fleet, construction, energy, estates, consultancy and common goods and services. There is a huge variety of CCS frameworks out there which provide important access to many public sector buyers. However, winning a place on a CCS framework does not automatically guarantee work. Although direct award is possible once you have a place on a CCS framework, suppliers may still need to compete through call-offs or further competitions depending on the framework rules. The Evolve Network Group are experts in CCS Framework applications successfully bidding into frameworks worth up to £7billion+ for our clients since 2023 with an overall 93% success rate.
Local Authorities (LAs)
Local Authorities are local government bodies such as local, city and county councils who are responsible for commissioning and delivering a wide range of local services such as adult social care, children’s services, public health, housing, homelessness support, transport, waste, highways, education support, environmental services, leisure, community services and facilities management to name a few.
Local Authority procurement can be especially relevant for suppliers in health and social care, housing support, community services, transport, construction, maintenance, professional services and place-based delivery. For suppliers, Local Authority bids often need to demonstrate local understanding such as knowledge of demographics, service pressures, safeguarding, community need, partnership working, mobilisation, social value and value for money.
Combined Authorities (CA) and Mayoral Combined Authorities (MCA)
Combined Authorities are groups of local authorities working together across a wider region. Mayoral Combined Authorities are combined authorities led by an elected mayor. New combined authorities are expanding across England as part of a “devolution revolution” to manage regional transport, skills, and housing, with major deals in progress for 2026 onwards. Key developments include new mayoral authorities in Cumbria, Cheshire and Warrington, Greater Essex, Hampshire and Solent, Norfolk and Suffolk, and Sussex and Brighton, each given devolved powers and funding from central government. They may commission or fund activity relating to regional transport, adult skills, employment support, economic development, regeneration, housing, net zero programmes, infrastructure and business support.
For suppliers, these new buyers provide fresh opportunities to access newly created funding specifically for service that support regional growth, skills, employability, transport, place-based investment or economic development.
Department for Education (DFE)
The DfE is responsible for education, children’s services and skills policy in England who publish opportunities in areas such as education programmes, skills and training, school improvement, children’s services support, digital platforms, research, estates, professional services and education-related frameworks.
DfE opportunities often require suppliers to demonstrate safeguarding, quality assurance, learner or child-centred delivery, measurable outcomes, data handling, stakeholder engagement and experience working in education or skills environments.
Department for Work and Pensions (DWP)
The DWP is responsible for welfare, pensions and employment-related support and is a major commissioner of services connected to employment, skills, health, disability assessment, digital delivery, estates and operational support and spends around £2.5billion a year on the procurement of goods and services.
Suppliers will find DWP opportunities linked to employment support, employability programmes, skills provision, health and disability assessments, contact centres, research, professional services and technology-enabled support. These opportunities often require strong evidence of outcomes, compliance, accessibility, safeguarding, data protection, performance management and the ability to work with people who may have complex needs or barriers to employment. It is crucial you have a high-quality evidence base, policies, procedures and necessary accreditations to be successful when bidding into central government departments such as the DWP.
Housing Associations (HAs)
HAs, sometimes referred to as registered providers or registered social landlords (RSLs), are major commissioners of housing-related goods and services. They often procure repairs and maintenance, planned works, construction, retrofit, compliance services, fire safety, cleaning, grounds maintenance, tenant engagement, housing management systems, care and support, and community investment services. Importantly, to meet the consistently high demands of new housing stock throughout the UK, there are several key construction frameworks house builders compete for places on, often split into geographical lots.
For suppliers, Housing Association bids often focus on resident experience, compliance, quality, safety, responsiveness, added value and social value. In areas such as repairs, compliance and building safety, buyers will usually expect strong operational evidence and clear performance management. For house building, safety, quality and environmental impact are key considerations as well as value for money, modern methods of construction and energy efficiency/performance.
Integrated Care Boards (ICBs) and Integrated Care Systems (ICSs)
ICBs are NHS bodies responsible for planning and funding most NHS services in their local area. ICBs may be involved in commissioning community health services, primary care support, mental health services, continuing healthcare, urgent care, elective recovery support, population health, patient pathways, digital health and local transformation programmes. For suppliers, ICB-related opportunities often require a strong understanding of local health needs, patient outcomes, integration with NHS pathways, clinical governance, safeguarding, data protection and partnership working.
ICSs are partnerships bringing together NHS organisations, Local Authorities and other partners to plan and coordinate health and care services across a local area. An ICS is not usually a single commissioning body in the same way as an ICB. Instead, they are a system-level partnership focused on integration, population health, service transformation, prevention, community services, workforce planning and digital programmes. Suppliers working in health, care, community services, digital health, prevention or transformation may need to understand ICS priorities because they can shape local commissioning decisions.
NHS England (NHSE), NHS Trusts and NHS Foundation Trusts
The NHSE oversees health service planning and commissioning nationally and regionally, whilst also supporting ICBs, and has responsibilities linked to specialised services, national frameworks, digital transformation, workforce programmes and service improvement. For suppliers, NHSE opportunities may involve national health programmes, specialist services, digital health, workforce support, consultancy, transformation, data, estates and service improvement.
NHS bids usually require strong compliance, quality, clinical governance where relevant, information governance, safeguarding, equality and accessibility considerations, and clear evidence of previous delivery in complex environments.
NHS Trusts and NHS Foundation Trusts are NHS provider organisations who may run hospitals, mental health services, community services, ambulance services or specialist care services. These organisations procure a wide range of clinical and non-clinical goods and services, including medical equipment, estates, facilities management, staffing, diagnostics, catering, cleaning, digital systems, consultancy, training and patient support services. For suppliers, opportunities with NHS Trusts often require evidence of safe delivery, service continuity, patient impact, compliance, responsiveness, workforce capability and value for money.
Ministry of Defence (MoD)
The MoD is responsible for defence and military procurement of defence equipment, technology, infrastructure, estates, training, logistics, maintenance, security, research, engineering, construction, professional services and operational support.
Suppliers bidding into the defence sector may need to consider security clearance, resilience, supply chain assurance, cyber security, mobilisation, technical standards, risk management and long-term support requirements.
Ministry of Justice (MoJ)
The MoJ is responsible for justice, courts, prisons, probation and related services who publish opportunities involving prison services, probation, rehabilitation, court services, facilities management, security, digital systems, estates, professional services, offender support and legal aid-related services.
MoJ bids often require suppliers to demonstrate strong governance, safeguarding, security, risk management, service continuity, equality considerations, information assurance and experience working with complex or vulnerable user groups.
His Majesty’s Prison and Probation Service (HMPPS)
HMPPS is an executive agency of the MoJ. It manages prison and probation services and commissions related services across custody, rehabilitation, offender management and resettlement.
HMPPS-related opportunities may include education, rehabilitation programmes, facilities management, security, maintenance, health-related support, resettlement services, electronic monitoring, offender management systems and operational support. For example, the team at the Evolve Network Group worked across 2025 supporting a complex bid return for the recommissioning of a national framework for Community Support for Men across all UK prisons for MOJ & HMPPS, with a total contract value of £854,446,832.
Suppliers bidding into this environment need to show robust safeguarding, risk management, security awareness, continuity planning, workforce capability and experience working in sensitive or regulated settings.
Blue Light Organisations
Blue light organisations refers to emergency services and related public safety bodies, including police forces, fire and rescue services, ambulance services, Police and Crime Commissioners (PCCs), and in some cases emergency planning or resilience partnerships.
These organisations procure a wide range of goods and services to support frontline response, estates, workforce, vehicles, technology, community safety and operational resilience. Commonly procured services may include fleet management, vehicle maintenance, uniforms and personal protective equipment, facilities management, cleaning, training, digital systems, control room technology, security services, estates maintenance, health and wellbeing support, victim services, safeguarding support, community engagement, emergency planning and specialist consultancy.
For suppliers, bids into blue light organisations often require a strong understanding of operational continuity, public safety, risk management, safeguarding, data protection, security, mobilisation and service resilience. Buyers may also expect evidence of working in sensitive, high-pressure or regulated environments, and biddings should be cautious if they have limited experience in this area as they will likely be marked down when compared to their competitors.
Higher Education Institutions (HEIs)
HEIs include universities, colleges schools and other higher education bodies who procure a wide range of goods and services, including estates, facilities management, student support, information technology, research services, consultancy, training, construction, catering, cleaning, software and professional services. They are also an important procurer of construction-related services as HEIs look to expand or replace their existing physical infrastructure to meet continuing increases in demand.
For suppliers, higher education procurement can be attractive because universities often have large estates, complex digital requirements, research activity, student-facing services and specialist operational needs, so the contracts they issue can be in significant in value.
Environment Agency (EA) and Forestry Commission (FC)
The EA is a public body sponsored by Defra involved in environmental protection, flood risk management, regulation, water and waste monitoring, incident response, and environmental resilience. The FC is also a Defra-sponsored public body, responsible for protecting, improving and expanding woodlands in England. One or both of these authorities may be relevant to suppliers working in land management, ecology, forestry services, environmental consultancy, sustainability, estate maintenance, biodiversity, tree planting, pest and disease management, and rural infrastructure.
For suppliers, opportunities in this area often require strong technical evidence, health and safety processes, environmental management, sustainability credentials, risk management, and experience working in regulated or operationally complex outdoor environments.
If you are new to bidding you may feel overwhelmed at the sheer variety and scale of different procurement bodies involved in the UK public sector and that’s understandable. The good news is that following the introduction of the Central Digital Platform, all public sector opportunities are now published on one central site for ease of access. Additionally, many authorities use the same platform, such as ProContract to manage their procurement process and once you are signed up to these you can have relevant opportunities sent directly to your inbox.
Once thing you must be is honest with yourself around your organisation’s current capabilities and experience. If you have experience in delivering a service to a local authority, can this truly be used and leveraged to create a high scoring response for a new opportunity with the NHS? If you have spent the last 10 years working exclusively with Housing Associations, can you realistically pivot and realign with the MOD’s buyer requirements? Each bid must be qualified on a bid-by-bid basis. There are always opportunities to work with new types of commissioner but you need to be targeted in your efforts to achieve success.
Evolve Network Group has proudly successfully bid into every single commissioner type with an industry high c93% success rate. Contact us today to see how we can help you be more successful in your bid and tender responses.
