Pharmacy First is a £15-per-consultation service designed to shift demand from overworked GP practices to underused community pharmacy capacity. The funnel is simple on paper: a patient walks in or is referred, the pharmacist consults, the NHS pays £15. On the ground, the funnel leaks everywhere. This article maps the leakage by region, using PharmSee's 13,147-pharmacy register as the denominator.
What "leakage" means here
Pharmacy First revenue leakage is the gap between a catchment's theoretical ceiling (every eligible referral converted) and its likely actual capture. We define:
- Ceiling per site: £6,000/year — roughly 400 consultations × £15. This is not a cap — well-run urban high-street sites exceed it — but it is the planning anchor PharmSee's market analysis pages use for catchment aggregation.
- Urban capture rate: 55-65% (PharmSee estimate, not measured)
- Rural/coastal capture rate: 35-45% (PharmSee estimate)
- Leakage: ceiling × (1 − capture rate)
These percentages are analytical judgement calls, not measurements. They derive from workforce-density data, referral relationship observation, and what multi-site operators tell us their actual capture looks like. Treat them as directionally correct, not as gospel.
Liverpool: the most-studied catchment
Our cycle 12 Liverpool analysis mapped the L1 1JJ 3-mile catchment in detail. Cycle 14 re-verified the numbers:
- 106 pharmacies in the 3-mile ring
- Total annual Pharmacy First ceiling: 106 × £6,000 = £636,000
- Urban capture rate (estimate): 55-65%
- Captured revenue range: £349,800-£413,400
- Estimated leakage: £222,600-£286,200
That £222k-£286k is the headline number. It represents the annual revenue opportunity Liverpool's Merseyside catchment is leaving on the table because some subset of consultations never happen — either the branch is understaffed, the consultation room is occupied, the GP referral relationship is thin, or the patient walks past.
The wider English urban comparison
Using the same 3-mile-radius ceiling model across the cities PharmSee has already mapped in its GP-to-pharmacy ratio atlas:
| City | Pharmacies (3mi) | Ceiling | Capture 60% | Leakage |
|---|---|---|---|---|
| Liverpool L1 1JJ | 106 | £636,000 | £381,600 | £254,400 |
| Birmingham B1 1AA | 150 | £900,000 | £540,000 | £360,000 |
| Manchester M1 1AE | 116 | £696,000 | £417,600 | £278,400 |
| Leeds LS1 1UR | 94 | £564,000 | £338,400 | £225,600 |
| Sheffield S1 2GJ | 67 | £402,000 | £241,200 | £160,800 |
| Nottingham NG1 5FS | 84 | £504,000 | £302,400 | £201,600 |
| Leicester LE1 5FQ | 93 | £558,000 | £334,800 | £223,200 |
| Newcastle NE1 7RU | 85 | £510,000 | £306,000 | £204,000 |
| Bristol BS2 8HW | 66 | £396,000 | £237,600 | £158,400 |
Total across nine urban cores: £5,166,000 ceiling / £2,066,400 estimated leakage. The largest absolute leakage is Birmingham at £360,000 — largest not because Birmingham has the weakest capture rate, but simply because it has the most pharmacies in the 3-mile ring.
The rural leakage story is different
Rural and coastal catchments have a lower capture rate (35-45%) but also a vastly smaller ceiling. The absolute leakage numbers are modest; the proportional leakage is severe.
Using cycle 14 Cornwall and Lincolnshire corridor data:
| Corridor | Pharmacies | Ceiling | Capture 40% | Leakage |
|---|---|---|---|---|
| North Cornwall (Bude-Padstow 45mi) | 8 | £48,000 | £19,200 | £28,800 |
| Lincolnshire Fens corridor | 22 (Wisbech 10mi) | £132,000 | £52,800 | £79,200 |
| Mid-Wales (Brecon-Aberystwyth) | 0* | — | — | — |
*PharmSee's Welsh pharmacy data is a known integration gap — see our devolved-nation coverage.
Three quarters of the North Cornwall ceiling is going uncaptured on these estimates. That's not because Cornish pharmacists are less motivated — it's because rural single-pharmacist sites have lunch breaks, fewer backup pharmacists, less GP referral relationship density, and patients who simply drive to the next town instead of walking in.
Which regions are "worst" on a per-pharmacy basis
Aggregating the urban core data and the rural corridor data into a per-pharmacy leakage figure:
| Region-archetype | Leakage per site | Drivers |
|---|---|---|
| Urban high-street (9-city average) | ~£2,400 | Mostly capture-rate ceiling, not referral volume |
| Rural coastal (Cornwall model) | ~£3,600 | Referral volume limits; single-pharmacist cover gaps |
| Rural fens (Lincs corridor) | ~£3,600 | Same drivers as coastal; seasonal swings |
| Suburban neighbourhood | ~£3,000 | Middle-ground; capture rate runs 45-55% |
Counter-intuitively, rural corridors leak more per pharmacy than urban cores. The urban ceiling is bigger in absolute terms, but the urban capture rate is higher, so proportionally less is being lost. The rural sites have the worst capture rate, and that drags the per-site leakage number above the urban one.
What to do about it
For a multi-site operator, the highest-leverage improvements depend on which archetype your branches fall into:
- Urban chains: invest in consultation-room availability and counter-triage. The leakage here is mostly "the patient arrived but we couldn't see them". Fixing that is a staffing and workflow problem, not a demand problem.
- Rural single-pharmacist sites: the binding constraint is the pharmacist being available at all. Locum cover gaps directly translate to £15 × captures lost. Paying 10% more for locum cover that actually shows up is often cheaper than the foregone Pharmacy First revenue.
- Suburban branches: the bottleneck is usually referral relationships. One structured visit per quarter to every GP practice within a mile of the branch, with a briefing pack and a direct pharmacist contact, moves the capture rate more than any other single intervention we've observed.
The honest limit of this analysis
Every number above is an estimate built on top of the £6,000 per-site ceiling and the 40-60% capture rate bands. The ceiling is a reasonable planning anchor but not a measured ceiling at most sites. The capture rate ranges are derived from operator conversations and workforce-density observations, not from NHS BSA consultation volume reporting — which, at the time of writing, is not published at sub-ICB granularity.
When NHS BSA does publish site-level Pharmacy First consultation volumes — which is on the roadmap for Q4 2026 — PharmSee will re-run this analysis with measured capture rates and the leakage numbers will change. In the meantime, these estimates give operators a usable map of where the money is going, or more precisely, where it is not.
