What to expect from a Marston’s AOM visit

Last updated: 26 June 2026

Your Area Operations Manager doesn’t arrive to catch you out—they arrive to check you’re running the pub properly and protecting your margins. Most licensees know this visit is coming, but very few actually prepare for it, and that’s where the friction starts. A Marston’s AOM visit is fundamentally a stock audit combined with a cellar inspection and a review of your till reconciliation. If your records don’t match your physical stock, if your cellar temperatures are drifting, or if your till variance is all over the place, that conversation becomes uncomfortable fast. The good news: proper preparation takes a day, not a week, and you can catch legitimate losses before they become a problem that costs you thousands. This guide walks you through exactly what happens during a Marston’s AOM visit, what they’re looking for, and how to prepare so you walk into that meeting with confidence.

What a Marston’s AOM visit actually is

An AOM visit isn’t a random compliance check. It’s a scheduled meeting between you (or your manager), the Area Operations Manager, and sometimes a cellar specialist from the brewery. The AOM’s job is to verify that you’re running the pub according to Marston’s standards, managing stock properly, maintaining cellar conditions, and reconciling your till and cash position. They’re not there to close you down—they’re there to identify problems before they spiral into cash loss.

In my fifteen years running a Marston’s pub, I’ve seen three types of AOM visits: routine checks (annual or every 18 months), follow-up visits after a previous issue was flagged, and unannounced visits when stock variance or till loss patterns trigger a review. The routine ones are the easiest if you’re prepared. The follow-ups are awkward only if you haven’t fixed the original problem. The unannounced ones catch people who aren’t keeping weekly records.

The most effective way to prepare for a Marston’s AOM visit is to complete a full stocktake and cellar temperature check at least three days before the appointment. This gives you time to investigate any variance, verify your records match your physical stock, and explain any anomalies before the AOM arrives. If you’re still scrambling the morning of the visit, you’ve already lost control of the narrative.

The three things an AOM checks first

1. Stock variance and cellar records

Your stock variance—the difference between what your till says you sold and what you physically counted—is the first number the AOM looks at. Stock variance greater than 3% on wet sales is a red flag that usually signals measurement error, wastage, or over-pouring rather than theft. A 1% loss on wet sales quietly costs a typical pub £3,000–£5,000 a year, which is why this number matters. They’re looking for evidence that you’ve counted your casks, kegs, and spirit bottles weekly and reconciled against till data.

The AOM will ask to see your cellar records: temperature logs, line cleaning dates, and keg/cask counts. If you’re running off a spreadsheet with dates missing or numbers that don’t reconcile, they’ll flag it. If you’ve got nothing written down, they’ll note that as a control weakness. If you’ve got a disciplined weekly count routine—even if it’s just a notebook and a dipstick—they’ll see you’re managing the cellar properly.

2. Cellar condition and equipment

They’ll walk the cellar with a thermometer. They’re checking that your cellar temperature is sitting between 12°C and 15°C (draught quality depends on it), that your lines are clean (visible slime or sediment is a problem), and that your gas is set correctly. They’ll look at your line cleaning logs and your CO₂ pressure gauges. If you’ve got a disconnected line or a burst keg that’s been sat there for three days, they’ll see it.

This is also where they check for stock that shouldn’t be there—spirits that belong to your tied account but are being served from non-Marston’s bottles, or cask beer from other breweries. They’re protecting the brand consistency as much as your cash position.

3. Till reconciliation and cash control

They’ll review your last four weeks of till readings. They’re checking that your daily cash-up balances to within a pound or two, that your void/refund logs make sense, and that there’s a clear pattern rather than wild swings. If your till variance is ranging from +£200 to −£150 with no explanation, that’s a control issue they need to address with you. If your variance is tight (within ±£20 most days), they move on. The number that actually matters is wet GP by line, not a single headline stock figure. They want to see that you can account for where the money went.

Preparing your stock records and cellar

The preparation phase is where most licensees either sail through or stumble. Here’s what you need to do at least three days before the visit:

Step 1: Complete a full physical stocktake. Count every cask and partial keg (use a dipstick to measure the depth—guessing is useless). Weigh your open spirit bottles. Count your alcopops and bottled beer against your till records. Write everything down with dates and times.

Step 2: Reconcile physical stock against till data. Pull your till reports for the same period. Work out what you should have sold in each category (draught, cask, spirits, other). Does it match your stock movement? If there’s a gap, investigate: Did someone forget to ring something up? Was there a line spill you didn’t log? Did the deputy manager give away a free pint? Spirits hide losses in over-pouring (a free-poured 25ml is often 32–35ml), draught hides it in poor cellar temperature and bad line cleaning waste, and most stock ‘theft’ is actually measurement error and forgotten wastage.

Step 3: Review your cellar records for the last eight weeks. Pull together your temperature logs, line cleaning schedules, and any maintenance notes. If you’ve got gaps, fill them now with honest entries. If you haven’t been logging temperatures weekly, log the last eight weeks of data based on your memory of conditions—but be honest about what you actually know versus what you’re guessing.

Step 4: Check your till reconciliation for the last four weeks. Print out your daily cash-up summaries. Highlight any days where the variance was unusual (more than ±£50). Have an explanation ready for those days. Usually it’s a voids log entry or a training issue with a new member of staff, not a disaster.

Step 5: Walk the cellar as if you’re the AOM. Look at the lines—are they clean? Check the cask valves—are any leaking? Look at the gas pressure gauges. Feel the cellar temperature by hand. If something looks rough, fix it before the visit. A visible problem that’s already addressed looks a lot better than a visible problem that’s being ignored.

At my own pub I was running stock on a tangle of spreadsheets and still losing track of partial kegs and spirit measures. I built a simple count routine around a dipstick and a set of scales, and the weekly variance went from guesswork to a number I could trust within a fortnight. The AOM noticed the difference immediately—not because I was suddenly perfect, but because I could explain every variance.

Till reconciliation and cash position

Your till reconciliation is the financial proof that you’re running the pub properly. The AOM wants to see that you’re completing a daily cash-up (comparing the cash in the till to the till reading), that your voids and refunds are logged, and that your variance is predictable and small.

Here’s what you need to show:

• Daily cash-up sheets for the last 28 days, signed and dated.
• Till readings (opening balance, closing balance, takings) that tie to your cash position.
• A void/refund log that explains any unusual entries (staff meal, training voids, system corrections).
• A weekly P&L summary showing your sales by category and your gross profit percentage.

If you’re using an EPOS system (which most Marston’s pubs are), the AOM will ask to pull reports directly from the system. They’re checking that your closing till balance matches your physical cash count. If there’s a persistent gap—say, you’re always down £30 at the end of the week—that’s a training issue or a control issue that needs addressing.

One thing most licensees don’t realise: the AOM isn’t looking for perfection. They’re looking for consistency and evidence that you’re aware of your numbers. If your till variance is tight, your cash reconciliation is clean, and you can explain the two weeks where you were down £15, that’s a professional pub. If your till reconciliation is sloppy, your voids are unexplained, and you don’t know what your GP percentage is, that’s a red flag that something isn’t being managed properly.

Common issues AOMs flag—and how to avoid them

After fifteen years, I’ve seen the same problems flagged repeatedly. Here’s how to avoid being that licensee:

Issue 1: Stock variance that can’t be explained

If your variance is 5% or higher on wet sales, the AOM will ask for an explanation. The honest answer in most cases is: sloppy measuring, forgotten wastage (a burst line, a returned cask), or over-pouring. If you can’t explain it, they’ll assume it’s a control issue and will ask you to implement tighter controls. Use StockTap pub stock app or a simple spreadsheet to track your weekly variance by category. Spot patterns early.

Issue 2: Cellar temperatures that drift

If your cellar is running at 16°C or higher, your cask beer is warming up and spoiling faster. You’ll get more wastage and more complaints about quality. If it’s below 10°C, you’re risking cask ale frosting. Log your temperature every single day. If you’ve got a temperature problem, you’ve got a maintenance problem (faulty cooler, blocked vents, too many kegs in a small space). Show the AOM you’re aware of it and that you’ve got a plan to fix it.

Issue 3: Missing or vague line cleaning logs

If you can’t show when your lines were last cleaned, the AOM will note it as a control weakness and may ask for an immediate deep clean before the next visit. Line cleaning schedules vary by line type and usage—typically every two to three weeks for heavily used lines. Document it. If you’ve missed a clean, schedule it before the visit.

Issue 4: Till variance that’s all over the place

If you’re up £200 one day and down £150 the next with no pattern, that’s a sign either that you’re not cash-up properly, or that you’ve got a training issue with multiple staff members on the till. The AOM will ask you to tighten your cash handling procedure and may ask for additional till training. It’s fixable, but it needs to be acknowledged and addressed.

Issue 5: Tied stock being sold from non-Marston’s bottles

This is a big one. If the AOM finds that you’re serving Marston’s bitter from a non-Marston’s bottle, or that you’re using non-tied spirits, they’ll flag it as a breach of your tenancy agreement. It’s not a small thing—it affects the brand, and it affects the brewery’s ability to track what’s being sold. Use the bottles and casks you’re supplied with. If you need to change something, ask first.

The conversation after the walk-round

After the AOM has reviewed your records and walked the cellar, they’ll sit down with you and discuss what they’ve found. This is where the actual value of the visit happens. If everything is tight, they’ll acknowledge it and move on. If there are issues, they’ll discuss them with you and agree on actions.

Common outcomes:

• No issues flagged: You’re signed off. They’ll typically visit again in 12–18 months unless something changes.
• Minor issues (temperature logs incomplete, line cleaning schedule needs clarification): They’ll ask you to correct these and will follow up in three months.
• Control issues (high stock variance, loose till reconciliation, cellar condition problems): They’ll agree on a remedial action plan with specific targets and timescales. You’ll be re-audited.
• Serious issues (evidence of tied stock misuse, persistent high stock loss, cash handling concerns): You’ll be asked to meet with a senior manager and may face suspension of trading until resolved.

The tone of the conversation depends entirely on how prepared you are. If you’ve done your homework, you can say, “I noticed the variance was 2.8% this month, up from 1.9% last month. We had a new team member on spirits for two weeks, and I think the issue is over-pouring. I’ve done additional training with them this week, and I expect to see that tighten back down next month.” That’s a conversation between professionals. If you’re unprepared and defensive, it’s a different conversation entirely.

How to stay audit-ready year-round

The best preparation for a Marston’s AOM visit isn’t last-minute cramming—it’s running your pub with proper records from day one. Here’s the minimum you need to do every week:

• Complete a physical count of casks, kegs, and open spirit bottles.
• Log your cellar temperature at least three times a week.
• Reconcile your stock movement against till data the same day (not three weeks later).
• Complete a daily cash-up with a signed and dated summary.
• Review your weekly P&L and note your GP percentage by category.

If you’re doing this already, the AOM visit is just a formality. If you’re not, start now. The difference between a tight operation and a sloppy one usually shows up within three weeks. SmartPubTools has built stock tracking and cellar management tools specifically for this, but honestly, a spreadsheet and a notebook will do the job if you’re disciplined about it. The tool matters less than the routine.
