NHS payment models determine how providers are paid for delivering care, services, and technology, and they play a critical role in how innovations are adopted and sustained. This page explains how NHS payment mechanisms work in practice and what they mean for organisations looking to work with the NHS. This page aims to answer the following questions:
- How do NHS payment models work, and why doesn’t the NHS use a single pricing approach?
- What are aligned payment and incentive (API) models, and when are they used?
- What is low volume activity (LVA), and how does it differ from other payment mechanisms?
- When and why does the NHS use activity‑based payments instead of block or fixed payments?
- What are local payment arrangements, and when are they applied?
- How do licence, subscription, and managed service contracts work for digital and technology‑enabled services?
- How does the NHS differ from other health systems as a buyer, and how does this affect payment and adoption decisions?
How do NHS payment models work?
The NHS uses a blended set of payment mechanisms, rather than a single pricing model. Payments depend on the type of service, provider, and commissioning arrangement. NHS England outlines several models for paying providers.
Aligned payment and incentive (API) models
What it is: The main payment mechanism for NHS trusts and foundation trusts delivering most NHS services.
How it works: Providers receive a fixed annual payment agreed in advance, based on expected activity and service plans. Some services (such as elective care and emergency care) include variable payments linked to actual activity, with incentives for meeting best practice standards.
Why it is used: API is designed to encourage collaboration, support financial stability, and shift the focus away from maximising activity towards improving outcomes, quality, and efficiency.
Who it applies to: Most NHS provider relationships with commissioners where the annual contract value is above £1.5 million.
Low volume activity (LVA) block payments
What it is: A simplified block payment for NHS services where activity levels are small.
How it works: Instead of paying per treatment or appointment, commissioners make a single fixed payment to cover all agreed services for the year. This avoids complex invoicing for low value contracts.
Why it is used: LVA reduces administrative burden and ensures services remain viable even when patient numbers are low.
Who it applies to: NHS provider contracts with an expected annual value of £1.5 million or less, where NHS England has determined an LVA arrangement is appropriate.
Activity-based payments
What it is: A pay-per-activity model where providers are paid for each unit of care delivered.
How it works: Each service is paid at a nationally set unit price (for example, per procedure or appointment), adjusted for local cost differences. Providers are paid more when they deliver more activity.
Why it is used: This approach supports patient choice and is well-suited to competitive or outsourced services.
Who it applies to: Primarily non-NHS providers (such as independent sector providers) or community provider delivering services where NHS national prices apply.
Local payment arrangements
What it is: A locally agreed payment approach used when no national mechanism applies.
How it works: Commissioners and providers negotiate prices locally, considering costs, efficiency, service design, and local priorities (for example, service transformation or tackling health inequalities).
Why it is used: Local arrangements provide flexibility where services are specialised, innovative, new, or not covered by national prices.
Who it applies to: Any activity not covered by API, LVA, or activity-based payment, including some primary care services, specialised services, or new models of care.
Licences, subscriptions, and managed service contracts
What it is: A payment model increasingly used for digital health, diagnostics, and technology-enabled services, where traditional activity-based tariffs are less appropriate.
How it works: Providers receive payment through recurring licences, subscriptions, or managed service agreements, often based on access to technology, software, or ongoing service support rather than per patient or procedure. Payments may be tiered by usage, user numbers, or service scale, with performance or outcome incentives sometimes included.
Why it is used: This model enables predictable budgeting and reflects the value of technology and service management rather than discrete clinical activity.
Who it applies to: Providers of digital health solutions, diagnostics, technology-enabled services, and other non-traditional care delivery models where API, LVA, activity-based payments, or local arrangements are less suitable.
How does the NHS differ from other health systems as a buyer?
The NHS is a publicly funded, single payer system, which shapes how it adopts and pays for innovation. As a result, the following characteristics influence decision-making and adoption:
- Decisions must be transparent, evidence based, and defensible
- The system is highly risk averse, prioritising patient safety and equity
- Procurement focuses on system‑wide value, not just return on investment for individual organisations
- Adoption is often driven by national priorities, workforce pressures, and service sustainability, not purely financial performance
As a result, innovation uptake depends as much on system readiness, evidence generation, and pathway fit as on price or technical performance alone.
NHS payment models are shaped by service type, scale, and system priorities, not just activity or price. Understanding how and why different payment mechanisms are used is essential for designing services and innovations that are affordable, sustainable, and adoptable within the NHS.
