WORKPLACE COFFEE
Bean to Cup Coffee Machines for Offices
Quick answer
An office bean-to-cup machine costs £130–£290 a month to rent including servicing, filtration and breakdown cover. Size it on headcount in the building on the busiest day, at roughly 2.2 cups per person per day, and check the peak-hour figure rather than the daily total. Below 40 people a compact plumbed fresh-milk unit is enough; above 150 people you need either a high-output machine or two points.
Office coffee is judged in a 40-minute window. Everyone arrives, everyone wants the same drink, and the machine either holds up or generates a queue that people remember. Facilities teams are usually sold on daily capacity and then live with a peak-hour problem, so we size the other way round.
Who this is for
Sizing by headcount and attendance pattern
Use attendance on the busiest day, not the payroll number. Hybrid offices routinely run at 45–65% of headcount, but Tuesday and Wednesday can hit 85%. Assume 2.2 cups per attending person per day, with 35–40% of those pulled in the first 90 minutes. A 100-person office at 80% attendance on a Tuesday needs roughly 176 drinks, about 65 of them between 8:30 and 10:00 — so a machine rated near 70 cups an hour, not the 30-cup unit its daily total suggests.
One machine or two points
Above roughly 150 attending staff, two smaller machines on separate floors beat one large one. Two points halve the queue, survive a single breakdown, and usually cost less in total than a single high-output unit. The exception is a single-floor office with one kitchen, where a twin-grinder high-output machine is the cleaner answer.
Milk, hygiene and the Monday-morning problem
Fresh milk is what people want and what makes the offer feel worth having. It also needs a chilled cabinet beside the machine, an automatic rinse, and a chemical clean of the milk circuit. In offices with no dedicated operator, specify a machine that prompts and runs its own cleaning cycle and set the schedule around Friday evening and Monday morning — milk left in a line over a weekend is the most common hygiene failure in workplace coffee.
What procurement should ask before signing
Ask for the peak-hour rating, not daily capacity. Ask which filtration unit is fitted and at what interval it is changed. Ask for the response time in hours and what happens when it is missed. Ask whether the price is fixed for the term or indexed. Ask what the machine costs to exit early, and whether the agreement converts to ownership. Five questions, and they separate a serious quote from a cheap monthly figure with costs hidden behind it.
Cost per cup, the number that actually matters
Rental divided by cups is the honest comparison. A £180 machine producing 3,500 cups a month is 5p a cup before coffee and milk; the same machine in a 20-person office producing 900 cups is 20p. Add roughly 12–18p of beans and 8–12p of milk per drink, and an office coffee programme lands between 25p and 50p a cup all-in — against £3.20 or more outside the door.

Frequently asked questions
How much does an office coffee machine cost per month?
£99–£145 a month for a small office, £180–£260 for 50–100 people, and £380 or more where two machines are needed. Those figures include servicing, filtration and breakdown cover; beans and milk are additional.
What size coffee machine do I need for 100 staff?
At 80% attendance and 2.2 cups per person, roughly 176 drinks a day with about 65 in the morning peak. That means a machine rated near 70 cups an hour — mid-range twin grinder — not an entry unit sized on the daily total.
Should the office machine use fresh milk?
Yes, in almost every case. Powdered milk is acceptable only in back-of-house settings with no visitors. Fresh milk needs a chilled cabinet and a daily clean cycle, both of which should be in the specification from the start.
Can we charge staff or tenants for drinks?
Yes — machines can be fitted with card or account payment, which is common in serviced offices and co-working buildings. It adds cost to the install, so decide before the machine is specified rather than after.
What is a realistic cost per cup in an office?
25p to 50p all-in, covering machine, beans and milk, depending on volume. Low-volume offices sit at the top of that range because the fixed monthly cost is spread over fewer drinks.
