Two ways to work with us

A live subscription, and a tailored deep-dive.

The subscription keeps the whole dispensing market - including the branded-product plays - in front of the practice every day, for a simple per-patient fee, and your first Tailored Report is included. The report is a practice-specific deep-dive that turns your own history into, typically, around £50,000 of recoverable margin a year; additional reports are an optional add-on whenever you want to re-baseline.

Live Market Subscription
The whole dispensing market, live, shared across the practice and the prescribing team. Refreshed every working day; nothing to set up.
50pper dispensing patient, per year

What the subscription includes:
  • Search any drug across PSUK, AAH, Alliance and Clarity, priced net of the national MDS rebate schemes, with live stock and 90-day price history
  • Margin winners and losers on every line versus the Drug Tariff, with live price concessions and Tariff changes flagged

Additional Tailored Report Add-on
Your first report is included with the subscription. Commission a fresh deep-dive whenever you want, on your latest data, finishing with a live findings call with the founders.
TBCfurther reports, priced on list size
The first Tailored Report comes with your subscription. Each additional report is priced on your dispensing list size (to be confirmed), run on your most recent invoices, FP34 and ePACT2 data, so you can re-baseline whenever your prescribing or the market has moved.
What the deep-dive covers:
  • Your practice's own dispensing history analysed line by line, from your invoices, FP34 and ePACT2 data
  • Every profitable prescribing switch quantified, including the brand-level plays: generic-to-brand rebate lines, brand-tariff plays and MDS / rebate-scheme switches
  • NHS contract modelling, a QOF review, and local population and housing-growth research for your area
  • Priority access to exclusive MDS and manufacturer rebate schemes
  • A live Teams readout with the founders, and optional hands-off implementation

The Live Market subscription is 50p per dispensing patient, per year (annual contract, 6-month break clause) and now includes the branded-product plays in your live dashboard and your first Tailored Report. Additional Tailored Reports are priced on your dispensing list size (to be confirmed), run on your latest data. The live dashboard keeps you ahead day to day; the report recovers the margin your history is leaving behind.

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.

Why practices trust the numbers

Proven on a live practice
The method was built and run against a working NHS dispensing practice, not a demo.
Reconciles to your FP34
Income is audited back to source, to within a fraction of a percent, before anything is reported.
Signed off by a dispensing GP
Every material figure is checked by a GP who dispenses, never generated and left unchecked.
Live, every working day
The market dashboard refreshes daily from the wholesalers, the Drug Tariff and the concessions.
What it does

A clear, live picture of where your dispensary stands.

Reimbursement, the Drug Tariff, concessions, rebates and procurement all move independently, and a line that made money last quarter can quietly turn into a loss. RxMargin tracks it line by line and refreshes every working day, so the whole market is in front of you in seconds, not minutes.

Drug-level margin

Net cost versus reimbursement on every line, so loss-making and over-tariff items surface instead of hiding in the average.

Cheapest supplier, in stock

The best in-stock price for any line across PSUK, AAH, Alliance and Clarity, priced net of the MDS rebates, with 90-day history, so you always buy well.

Rebates & concessions

Supplier rebate schemes and live price concessions tracked, flagging where you are below the rates you could earn.

Prescribing wins

For each multi-source molecule the dashboard leads with a plain one-line answer: write it generically, dispense the cheapest source you can actually get, and keep the per-script margin. The full price ladder sits behind a toggle.

Price concession (CPE) reports

It spots the generics you are buying above the Drug Tariff with no concession in force, then builds a ready-to-send CPE supply-issue report: a pre-filled spreadsheet plus an email draft, so you can push for a concession in a couple of clicks.

Prescriber Dashboard, price-blind

Every clinician gets their own price-blind login with the practice's preferred lines, across two tabs: Starting doses and Switches. Costs and margins stay with the partners. Included with the subscription.

Branded products + Tailored Report

Branded-product plays are included in your live dashboard, and your first deep-dive of your own history - typically around £50,000 a year of recoverable margin - comes with the subscription. Additional reports are priced on your list size (TBC).

Included with the subscription

A prescriber view for the whole team, with prices kept private.

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.

  • Every prescriber, one shared view

    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.

  • Starting doses and Switches, in two tabs

    Two tabs cover the moment a script is written: Starting doses for what to initiate, and Switches for the preferred swaps. Each shows the recommended product, form and pack, with the clinically equivalent alternative alongside, so good decisions happen as the script is written, not audited months later.

  • Price-blind by design

    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.

On every screen in the practice

It is an app, too. On every screen.

RxMargin installs straight to the practice PC and to your phone like an app, with nothing to download from a store and no extra password. The live market, the cheapest in-stock supplier, your prescriber board and Tariff Watch are one click or tap away, full screen, and always showing the day's live figures.

The RxMargin app icon Install in one tap
  • One tap from your browser. No app store and nothing to maintain, just the same secure login pinned to the home screen.
  • There when it matters. It opens full screen and stays signed in, so it is with you on the ward round and at the dispensary bench.
  • Never a stale copy. It is the live site, refreshed every working day, so the app is always current.

On your phone, sign in at app.rxmargin.co.uk and tap Install app in the dashboard. On an iPhone (Safari), tap the Share icon, then Add to Home Screen; on Android (Chrome), tap Install app for a one-tap install. Subscribers and trial users alike.

On the practice PC, there is nothing to download. In Chrome or Edge, sign in at app.rxmargin.co.uk, then click the install icon in the address bar, or pick Install RxMargin from the browser menu. It opens in its own window, just like any desktop app. Subscribers and trial users alike.

Security & information governance

Built to be safe to put practice data on.

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.

Per-practice isolation

Each practice can only reach its own material. One practice physically cannot fetch another's files, access is blocked before the request is served.

Individual sign-in

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.

UK-hosted

Content is served from the UK behind an access-controlled front door, so practice material never sits on an open address.

Aggregate, not patient data

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.

DSPT and a written DPA

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.

Computed by rule, audited by a GP

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.

Why RxMargin

Specialist analysis, not generic software.

Who builds it

RxMargin is built and run by practising NHS GPs 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.

Common questions

What practices ask us first.

What do you need from us to start?
Nothing for the Live Market subscription, it is live the moment you sign in. For a tailored report we ask for your dispensing data (e.g. PD4(PxQ)), recent wholesaler invoices and supplier remittances, with a short checklist and a secure way to share them. No new software for your team to learn.
Can we install it on a practice PC?
Yes. It installs straight from Chrome or Edge, with nothing to download and no IT approval to set up: sign in at app.rxmargin.co.uk, then click the install icon in the address bar so it opens in its own window like any desktop app. If your browser is centrally managed, your IT team can allow it in seconds. You can pin it to phones the same way, via Add to Home Screen.
How is this different from what our accountant does?
Accountants work at the year-end, whole-dispensary level. We work at the individual drug-line level, every period, reconciling each line against what you were actually reimbursed and against the rates and concessions available that month. It complements your accountant; it doesn't replace them.
Is our data safe?
Yes. Each practice is isolated behind its own individual sign-in, hosted in the UK, with no shared link or login. The data we use is practice-level (dispensing, tariff and invoice figures), not patient-identifiable records. We provide a data-processing agreement before anything is shared.
Will this conflict with NHS prescribing guidance or our ICB?
No. Every switch shows its per-pack figures, and the clinician always decides what is clinically appropriate for the patient and in line with local guidance. You and your team choose which switches are right for your practice - we surface the figures, we do not prescribe.
How much time would it take us?
Minimal. The Live Market subscription needs nothing set up. For a tailored report you share your data once; the analysis, reconciliation and reporting are done for you and delivered ready to act on.
What do we actually get back?
From the Live Market subscription: the live market dashboard and the price-blind prescriber view, updated every working day, with an individual login for everyone on the team. From a tailored report: partner-ready reports, ready-to-send submissions (such as a price-concession claim) and a prioritised list of recoverable margin, delivered through your private portal.
What does it cost?
The Live Market subscription is 50p per dispensing patient, per year, billed annually: a 3,000-patient practice is £1,500 a year (about £125 a month), a 6,000-patient practice £3,000. It is an annual contract with a 6-month break clause and scales with your dispensing list, so a smaller practice pays less. The subscription includes the branded-product plays in your live dashboard and your first Tailored Report. Additional Tailored Reports are priced on your dispensing list size (to be confirmed), run on your latest data. The first look is free. See what the subscription includes →
