Methodology

How we rank UK GLP-1 clinics and pharmacies

PeptideClear ranks clinics and pharmacies offering GLP-1 medications (Mounjaro, Wegovy, Saxenda) for weight management. All listed providers are GPhC-registered. The ranking criteria differentiate within that compliant base.

Inclusion criteria (mandatory floor)

• · UK-licensed pharmacy with GPhC registration verified at listing and annually.
• · Prescriber on payroll or under contract with named GMC registration (not anonymous).
• · Published, transparent pricing on the public site.
• · Published switching, pause, and cancellation terms.
• · At least 12 months of UK trading history for GLP-1 specifically.
• · Published transparency on complaints handling and patient-facing policies.
• · No grey-market or compounded GLP-1 supply.
• · Cold-chain delivery infrastructure verified for tirzepatide and semaglutide.

Ranking criteria (weighted)

• Onboarding rigour (20%): full clinical consultation > pharmacist video call > questionnaire-only.
• Coach and check-in cadence (15%): weekly coach plus prescriber > monthly coach > no coach.
• Cost per typical maintenance month (15%): includes medication plus required service fees, normalised to maintenance dose.
• Switching policy clarity (10%): Wegovy to Mounjaro and vice versa with documented washout, restart dose, programme continuity.
• Maintenance-dose policy (10%): explicit maintenance pathway > available on request > not offered.
• Hormonal-context care (10%): HRT or fertility-aware co-prescribing, particularly relevant for women's clinics.
• UK delivery coverage and turnaround (10%): next-working-day UK-wide is the benchmark.
• Published transparency (10%): GPhC or CQC registration, clear complaints handling, and patient-facing policy disclosure score top.

High-touch vs low-touch differentiation

Clinics are categorised as high-touch (Numan, Voy, Manual, Juniper) or low-touch (Phlo, Pharmacy2U, SimplyMeds, Boots Online Doctor, Asda Online Doctor). The two categories are ranked separately because they serve different user needs. A high-touch clinic ranked first and a low-touch pharmacy ranked first are answers to different questions, not competitors.

What we explicitly do not measure

• · Clinical outcomes for individual users (we do not solicit or publish weight-loss outcomes by name).
• · Brand marketing spend or visibility (top-of-funnel reach is not a ranking signal).
• · Whether the clinic markets to specific demographics in advertising.

Refresh cadence

Rankings are reviewed quarterly. Material change triggers immediate re-review: pricing change > 10%, switching-policy change, GPhC registration change, prescriber turnover at the clinic, or a change in published complaints handling or patient-facing policies.

Conflict of interest

Some clinics are referral partners. Inclusion is not contingent on a referral relationship; the ranking criteria above apply equally. Affiliate-funded clinics and non-affiliate clinics appear side-by-side in directories.
