Marston’s CRP EPOS for UK Pubs 2026

Last updated: 11 April 2026

Most tied pub tenants assume their pubco’s EPOS system is just what they have to live with — but Marston’s CRP isn’t actually mandatory the way some licensees think it is. The real question isn’t whether CRP is the only choice, but whether it’s the right choice for how you actually trade. Many pub operators using CRP have never tested alternatives, so they don’t know what they’re missing — or what’s costing them money in hidden fees and integration headaches. This guide walks you through what CRP actually does, where it falls short for different pub types, and what you need to check with Marston’s before committing to it long-term.

What Is Marston’s CRP EPOS?

Marston’s CRP (Cash Register Protocol) is a cloud-enabled EPOS system built by Marston’s specifically for tied pubs. It’s not third-party software like Touchpoint or Toast — it’s Marston’s own platform, integrated with their pubco stock management, pricing controls, and financial reporting. If you’re a Marston’s tenant, you will hear about CRP because it’s the system the pubco actively recommends and supports.

The system runs on standard hardware (typically a touchscreen terminal, card reader, and kitchen display screen if you have one). CRP stores transaction data in Marston’s servers and pulls pricing, barcode data, and stock information directly from the pubco’s central system. This integration is CRP’s main selling point — Marston’s area managers don’t need to visit to check your till roll or reconcile stock. Everything flows through one system.

For licensees used to traditional standalone tills, this feels like progress. For licensees who’ve used independent EPOS systems at other venues, CRP can feel restrictive.

How CRP Works in Practice

When you ring a sale through CRP, the transaction hits three places simultaneously: your local terminal, Marston’s central system, and (if you’ve integrated accounting software) your bookkeeper’s records. That sounds efficient, but the speed and reliability of that flow depends on your broadband connection and Marston’s server load.

During quiet trading — a Tuesday lunchtime or a quiet Wednesday evening — CRP runs smoothly. Staff learn the basic navigation quickly. Payments process normally. Stock updates appear in the system within minutes.

The real test comes during peak trading. When I evaluated EPOS systems for Teal Farm Pub, the key test was always performance during Saturday night — specifically a full house with card-only payments, kitchen tickets printing simultaneously, and bar tabs running across multiple terminals. Most systems that look fine in a demo struggle when three staff are hitting the same terminal during last orders. CRP can struggle here too, particularly if your internet connection isn’t robust or if Marston’s servers are under heavy load across their entire estate.

The speed of your internet connection directly affects CRP performance during peak hours. If you have basic broadband (10-15 Mbps), you’ll notice lag. If you have proper business-grade connectivity (50+ Mbps with priority traffic), CRP runs significantly faster. Marston’s won’t tell you this matters until you complain about slow payment processing at 11pm on a Saturday.

What CRP Does Well

Integration with Marston’s Systems

If you’re a Marston’s tenant ordering stock through the pubco’s ordering system, CRP integrates seamlessly. You can see real-time stock levels, compare your sales data against Marston’s expected figures, and identify discrepancies quickly. This is genuinely useful if you have a proper stock control process in place. Most pubs don’t — they just order what they think they need — but if you do, CRP makes that easier than a standalone system would.

Centralised Pricing Control

Marston’s can push pricing updates to your CRP terminal instantly. If the pubco changes keg lager pricing across 500 tied pubs, it happens on your terminal without manual input. For a tenant, this removes the risk of accidental margin loss due to outdated pricing. For the pubco, it’s control.

Compliance Reporting

CRP automatically generates reports that Marston’s requires: daily till reconciliation, stock variance analysis, payment method breakdowns. You don’t have to remember to export data or email spreadsheets. That’s a genuine operational win if you’re managing 17 staff like I do across FOH and kitchen — the administrative overhead is lower.

Hardware Support

Marston’s has relationships with hardware manufacturers and will replace faulty terminals relatively quickly. You’re not stuck finding your own repair technician or waiting three weeks for a replacement. That matters when your till goes down on a Friday night.

Real Limitations You Need to Know

Lack of Flexibility

You cannot customise CRP significantly. If you want to add a custom menu category, change how discounts are applied, or integrate a third-party loyalty system, you’re limited to what Marston’s has already built. Other EPOS platforms allow much deeper customisation. This is particularly frustrating if you’ve migrated from an independent pub to a tied house and you’re used to controlling your own system setup.

Internet Dependency

CRP requires a constant internet connection to function fully. If your broadband drops during service, the terminal can continue taking payments temporarily using cached data, but reporting becomes unreliable and stock updates halt. I’ve spoken to operators whose CRP went into degraded mode during a Friday night when their router failed — they could still take payments, but couldn’t access current pricing or stock information. That’s workable if it happens once a year, not if your connection is unstable.

You need to invest in backup connectivity (a 4G router or secondary broadband line) if you rely heavily on real-time data. That’s an additional cost Marston’s won’t mention.

Performance Under Load

Marston’s CRP can experience slow transaction processing during peak hours when multiple terminals and kitchen screens are running simultaneously across the pubco’s server infrastructure. This isn’t unique to CRP — cloud-based EPOS systems all have this issue — but it matters more in high-volume venues. A quiet community pub won’t notice. A busy wet-led pub or a food-led venue with a kitchen display screen absolutely will.

Limited Stock Management for Complex Operations

CRP’s stock management works if you’re ordering through Marston’s distribution. But if you’re buying from independent suppliers (craft beers, local spirits, wines) or managing multiple cellar locations, CRP doesn’t integrate well. You end up managing those manually in a spreadsheet, which defeats half the purpose of having an EPOS system. Kitchen display screens save more money in a busy pub than any other single feature — but only if your EPOS system integrates properly with your ordering and stock data. CRP integrates with Marston’s ordering; third-party supplies are harder to track.

Tied Tenant Restrictions

This is critical and often overlooked: you may not have the contractual right to use an alternative EPOS system even if you want to. More on this below, but check before you go further.

Critical Tied Tenant Checks

Read Your Tenancy Agreement Before Making Any Decision

Your agreement with Marston’s will specify whether you must use CRP or whether you may use CRP. That distinction is everything. Some agreements require it. Others permit it but don’t mandate it. Very few explicitly prohibit it. Ask your area manager or pub advisor for the exact wording. Don’t assume based on what other tenants are doing.

Tied pub tenants need to confirm contractual EPOS freedom with their pubco before purchasing any system. This isn’t optional due diligence — it’s essential. If you buy a rival system and your agreement actually requires CRP, you’ve wasted money and created a conflict with your pubco.

Integration with Marston’s Accounting

If you’re required to use CRP or if you choose to use it, confirm with Marston’s exactly how transaction data flows to your accountant. If you use an independent bookkeeper or accountant, they’ll need CSV exports or API access to pull your sales data automatically. Some accountants integrate directly with CRP; others require you to export manually. Clarify this before signing up.

What Happens to Your Data When You Leave?

If you decide to leave your Marston’s tenancy (or Marston’s decides to terminate), what happens to 12 months of transaction history? Can you export it? Can your new landlord’s EPOS system import it? CRP won’t make this easy. Get the answer in writing before you commit.

What to Do If You Want Something Different

Confirm Your Contract First

If your tenancy agreement permits (or is silent on) EPOS choice, you have options. Do not proceed without written confirmation from Marston’s that you’re permitted to use an alternative. “I’ll sort it out later” has cost operators money.

Consider Alternative Systems

If you have flexibility, read our detailed pub EPOS system comparison for 2026 to evaluate platforms that might serve your specific trading model better. For wet-led pubs specifically, different systems have different strengths. An independent EPOS system gives you more control over pricing, discounts, and loyalty integration — but you lose the automated Marston’s integration.

Integrate Your Own Stock Management

If you use CRP but want better stock control than the Marston’s integration provides, you can layer in a separate stock management tool and manually sync data. It’s not seamless, but it works. Track independent supplier purchases separately and reconcile cellar counts more frequently than the pubco requires.

Get Your Broadband Right

If you’re using CRP, invest in proper business-grade broadband. A pub IT solutions guide covers this in detail, but the short version: if your ISP can’t guarantee 99% uptime and 50+ Mbps, you’re running on inadequate infrastructure for a cloud EPOS system.

Is CRP Worth It for Your Pub?

The answer depends on four things:

• Your trading model: If you’re wet-led (no food), CRP is adequate. If you’re food-led with a busy kitchen, you’ll hit its limitations faster.
• Your volume: Quiet pubs won’t notice CRP’s peak-hour performance issues. Busy pubs will.
• Your internet connection: Without proper broadband, CRP will frustrate you regularly.
• Your contract: If you’re required to use it, the decision is made. If you’re permitted to choose, evaluate honestly whether Marston’s integration actually saves you money versus the flexibility you’d gain with an independent system.

For most Marston’s tenants, CRP is workable. It integrates with the pubco’s systems, it’s adequately supported, and the monthly cost is predictable. It’s not the most innovative EPOS system on the market. It won’t give you advanced features like AI-driven waste tracking or multi-site analytics unless Marston’s builds them in. But for a straightforward tied pub with standard trading, it does the job.

The real cost of CRP isn’t the monthly fee — it’s the staff training time in the first two weeks and the lost sales during the transition. Budget for that. That hidden cost applies to any EPOS system migration, not just CRP, but it’s worth factoring in before you decide to switch.

If you’re using CRP and you’re unhappy with it, the constraint isn’t usually the system itself — it’s that you haven’t optimised your internet connection, or you haven’t integrated it properly with your stock processes, or you’re not using the reporting features that actually do save time. Talk to your area manager about getting proper training. Most operators are using about 40% of what CRP can actually do.
