NHS access to GLP-1 weight-loss medications (semaglutide and tirzepatide, branded Wegovy and Mounjaro) differs by UK nation. England is rolling out tirzepatide in phased cohorts via primary care, with full eligibility scheduled to take 9 to 12 years. Scotland funds it only through specialist weight-management services at lower BMI thresholds. Wales is implementing slowly through specialist tiers. Northern Ireland has no funded NHS route at present. PeptideClear summarises each nation's current eligibility and access path, last reviewed May 2026.
England
Cohort 1 live since June 2025. Cohort 2 launches 23 June 2026.
- BMI:
- BMI 40+ for Cohort 1 (Cohort 2 expected to broaden to BMI 35+ with comorbidities).
- Route:
- GP referral to NHS weight management specialist service. No GP-prescribing route yet.
- Medication:
- Tirzepatide (Mounjaro) per NICE TA1026.
Phased rollout means most adults outside Cohort 1 cannot access NHS GLP-1 yet. Ethnicity-adjusted BMI applies (2.5 kg/m² lower for South Asian, Chinese, Black African, African-Caribbean populations).
Scotland
Cleared by SMC for use, BMI 30+ specialist-only.
- BMI:
- BMI 30+ in adults, with at least one weight-related comorbidity, in specialist services.
- Route:
- Specialist weight management service referral, not GP. Variation by health board.
- Medication:
- Tirzepatide (Mounjaro). Wegovy also approved.
Scotland uses Right Decisions guidance. Patients in Scotland may have lower BMI threshold than England, but capacity at specialist services is the bottleneck.
Wales
NICE TA1026 implementation in progress 2026.
- BMI:
- Following NICE TA1026 (BMI 35+ with comorbidity, ethnicity-adjusted).
- Route:
- Health board specialist service. Cardiff and Vale, Aneurin Bevan, Betsi Cadwaladr at different stages.
- Medication:
- Tirzepatide (Mounjaro).
Wales is implementing TA1026 on a slower timeline than England. Postcode-by-postcode variation by local health board.
Northern Ireland
No NHS GLP-1 access yet. First specialist service planned 2026.
- BMI:
- TBD. Likely to mirror NICE TA1026 once funding is in place.
- Route:
- Currently no NHS route. Patients must use private route.
- Medication:
- Pending.
Northern Ireland HSC has not yet announced an NHS GLP-1 weight management programme. Several private pharmacies dispense in NI but cold-chain delivery has postcode exclusions.

Baseline panels to track
If you are working with a UK private doctor or NHS prescriber on a peptide protocol, these are the blood panels typically ordered at baseline for GLP-1 medications. Not a recommendation for self-administered testing.
- HbA1c. Baseline plus 12-week follow-up. The canonical metabolic marker tracked across UK NHS and private GLP-1 protocols. Captures glucose impact across a 90-day window.
- Fasting glucose. Baseline establishes pre-treatment glucose handling. NHS specialist services and private clinics use this alongside HbA1c.
- Lipid panel. Weight loss and GLP-1 therapy shift the lipid profile. Baseline allows the prescriber to track cardiovascular markers across the treatment cycle.
- Weight and waist circumference. Not a blood panel, but the canonical adjunct measure. Waist circumference tracks visceral adiposity more sensitively than weight alone.
