Built and run by dispensing GPs. Two ways to work with us: a live market dashboard your whole practice can use every day, and a tailored deep-dive that turns your own prescribing into recovered margin. We know how a dispensary trades, because we run one.
On the left, the live market dashboard your whole practice can use every working day. On the right, the latest from Tariff Watch. This is the heart of RxMargin.
There is also a deeper, one-off option: the tailored report takes your own dispensing apart line by line. See what it covers →
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.
That is the live market subscription. Practices that want a one-off, in-depth review of their own prescribing and contract can also commission a tailored report.
RxMargin is built to be quick. What used to take minutes a line takes seconds, so your team spends less time at the screen and more on patients. Across everything you dispense, that adds up to hours handed back every week.
Find what you need and get straight back to dispensing, line after line.
Multiplied across everything you dispense, the time saved is the benefit practices notice first.
A clean, quick tool designed by dispensing GPs for how a busy dispensary really works.
The subscription keeps the whole dispensing market in front of you every day. The tailored report turns your own history into, typically, around £50,000 of identified recoverable margin (depending on list size). Most practices start with the subscription and add the report.
The live dashboard is today and forward-looking. The tailored report recovers what your own history is leaving on the table. The two complement each other.
No data to send and nothing to set up. RxMargin Live Market is one universal dashboard, refreshed every working day, built entirely from public market data: the wholesaler prices, the Drug Tariff and the monthly price concessions that are the same for every dispensing practice in England. See today's biggest margin winners and losers, the best generics to buy right now, the cheapest supplier and live stock for any line, 90-day price history, every live concession, and a universal prescriber-switching view, generic to brand and ICS/LABA to a rebate inhaler. Share one login across the whole practice.
The lines whose margin moved most overnight, with shortage spikes and tariff or concession changes flagged, so you know what to re-check before you order.
Live price and availability across wholesalers for the same pack, so you always buy at the best price that is actually in stock. It is what most practices come to us for.
Every price concession the moment it is published, plus tariff moves tracked daily, so a practice never reimburses below cost on a concession line.
The generic to brand rebate switches and therapeutic-class moves, always showing the NHS impact, ready for the prescribing team, no practice data required.
A flat monthly subscription for the whole practice, pricing to be confirmed · the demo shows every name anonymised; subscribers see the live, real data
Want a one-off deep dive into your own figures too? That is the tailored report.
Every prescribing clinician gets their own login showing the practice's preferred lines at the point of prescribing. Costs, margins and figures stay with the partners. That is what makes better prescribing stick, without ever exposing commercially sensitive data to the wider team.
Not just the partners. Salaried GPs, registrars, ANPs and practice pharmacists all see the same agreed preferred lines, so the whole team prescribes from the same page.
The recommended product, form and pack for each therapeutic choice, with the clinically equivalent alternative alongside. Good decisions happen as the script is written, not audited months later.
The prescriber view never shows cost, margin or any figure. Commercial data stays with the partners and practice manager, which is exactly why partners are comfortable rolling access out to everyone.
The result: partners keep commercial data private, prescribers get clean clinical guidance, and the whole practice moves to its preferred lines together. It is a secure portal page, not another system to install: we set up a login for each prescriber, onboarding takes minutes, and it opens in the browser alongside your clinical system.

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 practising NHS GP with a keen interest in software development and how technology can transform the NHS and improve its efficiency. Ed built the RxMargin engine that turns raw tariff, invoice and dispensing data into recoverable margin.
A senior partner at a dispensing practice with years of experience and a sharp financial awareness of how a dispensary actually runs. Mark grounds every figure in the day-to-day reality of dispensing.
Final pricing is being confirmed. The Live Market subscription is a flat, ongoing fee for the whole practice. The tailored deep-dive is a one-off engagement, sized to your list. Most practices land with the subscription, then add the report when they want the full picture.
Pricing scales with list size, so a smaller practice pays proportionally less. We confirm the exact figure for your list size after an initial look. Prices will exclude VAT.
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.
