The idea is simple: you develop expertise in a clinical area, provide an intermediate service that keeps patients out of secondary care, and get paid for it. The reality is that the pathway from "interested GP" to "commissioned GPwSI/GPwER" is poorly signposted, inconsistent between ICBs, and full of unofficial gatekeeping.
Here's how it actually works in 2026.
The terminology
GPwSI (GP with Special Interest) is the older term, still widely used informally. GPwER (GP with Extended Role) is the updated terminology preferred by NHS England and the RCGP, reflecting a shift from "special interest" (implies enthusiasm) to "extended role" (implies formal competency assessment).
In practice, the terms are used interchangeably. What matters is: you have demonstrable competence in a defined clinical area, recognised by the relevant specialty and commissioned by your ICB or place-based team.
The areas where GPwSI/GPwER roles exist
The most established extended role areas are:
Dermatology — the largest GPwSI workforce. Roles typically include triage of 2WW referrals, management of inflammatory skin disease, dermoscopy, and skin surgery (excisions, biopsies). Accreditation usually requires the Primary Care Dermatology Society (PCDS) diploma or equivalent, plus supervision by a consultant dermatologist.
Musculoskeletal (MSK) — joint injection clinics, triage of MSK referrals, interface with physiotherapy and orthopaedics. Often linked to the Diploma in Musculoskeletal Medicine or sports medicine qualifications.
Minor surgery — excisions, incisions, joint injections. Requires a certificate of competence and annual audit of outcomes. This is one of the most accessible extended roles because many GP training programmes include minor surgery.
Mental health — typically focused on complex medication management (e.g., initiating ADHD medication in adults, clozapine monitoring in shared care, complex depression/anxiety). Less formalised than dermatology/MSK but growing in demand.
Women's health — contraception (DFSRH is the baseline), menopause management, early pregnancy assessment. The Advanced Training Skills Module (ATSM) in Women's Health provides the formal credential.
Urgent care/emergency medicine — interface roles in UTC/minor injury units, often linked to the DipIMC or similar emergency care qualification.
ENT, ophthalmology, cardiology (ECG interpretation), diabetes — smaller but established niches depending on local need.
How to get accredited
There is no single national accreditation process. Instead, the pathway typically involves:
Step 1: Get the qualification. Each area has an expected credential. For dermatology: PCDS Diploma or Cardiff MSc in Dermatology. For MSK: DMSMM or equivalent. For women's health: DFSRH + ATSM. For minor surgery: completion of a structured competency programme with logbook. Without the credential, you're unlikely to be considered regardless of your experience.
Step 2: Get supervised clinical experience. Most accreditation processes require a period of supervised practice in the specialist area — typically 6–12 months of regular sessions under a consultant or experienced GPwSI. This is often the hardest step because it requires a secondary care department willing to host you.
Step 3: Apply for accreditation. Some specialties have formal accreditation panels (dermatology has a structured process through the PCDS and local dermatology departments). Others rely on ICB-level approval based on your portfolio of evidence. You'll typically need: your qualification, evidence of supervised experience, a clinical audit, a case portfolio, and a supporting statement from your supervising specialist.
Step 4: Get commissioned. Accreditation alone doesn't guarantee work. You need your ICB (or the commissioning body for your area) to commission the service and fund your sessions. This is where politics, relationships, and local need intersect. Some ICBs actively commission GPwSI services to reduce secondary care referrals; others are cutting them to save money.
How the money works
Session rates for GPwSI work are typically higher than standard GP sessions — £600–£900 per half-day session is common, reflecting the specialist nature of the work and the cost avoidance for the system (each patient seen by a GPwSI is a patient not referred to secondary care at £200–£400 per outpatient appointment).
Commissioning models vary:
- Direct commissioning: Your ICB contracts with your practice to provide GPwSI sessions. Income flows to the practice and you're paid as part of your normal contract.
- Provider-to-provider: You work sessions in a secondary care department or community hub, funded by the hospital or ICB directly.
- Freelance/ad hoc: Some GPwSIs negotiate sessional work directly with local providers. Less stable but more flexible.
Typical income addition: 2–4 GPwSI sessions per week at enhanced rates can add £50,000–£100,000/year to your income, depending on the area, rate, and number of sessions. This is on top of your standard GP income.
The honest challenges
Getting the supervised experience is the bottleneck. Secondary care departments are stretched and not all are willing to supervise GPs. Persistence and networking are essential — approach consultants directly, attend specialty meetings, offer to help with clinics.
Commissioning is uncertain. ICBs can decommission GPwSI services with relatively little notice if funding priorities change. Don't over-invest in a single income stream.
Maintaining competence requires ongoing effort. Most accreditation requires annual audit, CPD in the specialty, and periodic re-accreditation. This isn't a "qualify once and coast" arrangement.
Not every GP should pursue this. Extended roles work best when they grow from genuine clinical interest and local population need — not when they're pursued solely for income. The GPs who burn out fastest in extended roles are those who took them on for the money while resenting the additional complexity.
How to get started
If you're early in the process: identify the area that genuinely interests you, check the qualification requirements, and start the credential. While studying, begin building relationships with the relevant specialty department in your area. Attend their teaching, contribute to audit, and make your interest known.
If you're qualified but not yet commissioned: approach your ICB's primary care team and ask what GPwSI services are currently commissioned and whether there are gaps. Prepare a business case showing the cost-effectiveness of the service (referral avoidance is the most persuasive argument).
The pathway is less clear than it should be. But for the right GP with the right interest and the right local context, extended roles are one of the most rewarding — professionally and financially — options in modern general practice.
