RxMargin is built and run by dispensing GPs - we run dispensaries ourselves, so we know exactly how a dispensary trades. We analyse your dispensing income line by line, across reimbursement, rebates, price concessions and procurement, and show you which lines lose money and how to recover it.
Why practices trust the numbers
Reimbursement, Drug Tariff changes, Category M, monthly price concessions, supplier rebates and procurement decisions all move independently. A line that made money last quarter can turn into a loss. Most practices simply don't have the time, or the tooling, to track it at the level where the money actually moves.
Illustrative of the approach. Findings and figures are specific to each practice's own data.
Net cost versus reimbursement for every line, so loss-making and over-tariff items surface immediately instead of hiding in the average.
Tracks supplier rebate schemes and monthly price concessions, flagging where you're below the rates you could be earning.
Identifies genuine shortage losses, concession-dependent risk and cheaper same-month sourcing you missed, with the value at stake.
Partner-ready reports, an interactive dashboard, and submission-ready workbooks, delivered through your own secure portal.
A fictional practice, fully built out: an interactive dashboard with a live switching-opportunities panel, the drug-level margin ledger and a best-value-by-condition view, plus a three-page partner-report PDF. Exactly the format you'd receive, with invented numbers.

We treat your data the way a practice has to. Hosting is in the UK, every practice is isolated, and access is by individual sign-in, there's no shared login and no open link.
Each practice can only reach its own material. One practice physically cannot fetch another's files, access is blocked before the request is served.
Each named user signs in with a one-time code to their own email. No shared passwords for you to manage, and access can be removed in seconds.
Content is served from the UK behind an access-controlled front door, so practice material never sits on an open address.
The analysis uses practice-level dispensing, tariff and invoice data (drug, pack, cost and reimbursement). It uses no patient-identifiable records and nothing from the clinical record, which keeps the governance burden proportionate.
We align to the NHS Data Security and Protection Toolkit and sign a data-processing agreement with your practice. You remain the data controller; we are your processor, with a defined retention and deletion policy.
Every reimbursement, cost and margin figure is computed by rule against the Drug Tariff, never guessed or estimated. No patient-identifiable data is involved, and a dispensing GP checks every material number against source and signs it off.
We provide a data-processing agreement, our DSPT position and our retention and deletion policy before any real practice data is shared.
RxMargin is built and run by practising NHS GP partners who dispense. The method was developed against real dispensing data from a working practice, encodes how a dispensary actually trades, and every material figure is audited by a dispensing GP before it reaches your portal, not generated and left unchecked.
A one-off onboarding fee to build your practice out, then a monthly subscription priced per 1,000 patients. No long tie-in, cancel with 30 days' notice.
Prices exclude VAT and are billed monthly to the partnership. Onboarding is charged once at sign-up. Pricing scales with list size, so a smaller practice pays proportionally less.
No-obligation first look: from a single period of your data we tell you whether there is enough recoverable margin to be worth your while, before you commit to anything.
NET::ERR_CERT_AUTHORITY_INVALID warning. The site itself is fine; the warning is caused by the network layer, not by anything wrong with rxmargin.co.uk.

A short, dated read on the Drug Tariff, contract and QOF changes that move dispensing income, and for our practices, a one-page weekly update each time the price concessions change, showing only the lines you dispense. Read the full Tariff Watch →
