EPOS system installation in the UK: what actually happens (2026 guide)
Installation is the part of an EPOS purchase nobody prices properly. Most of it is configuration, not screwdrivers, and a preconfigured shipment removes nearly all of it. Here is what the work actually is, what you still have to do yourself, and when a van and an engineer are genuinely needed.

Short answer
An EPOS installation has seven parts: menu build, printer pairing, cash drawer trigger, card terminal pairing, network setup, user accounts and staff training. For a single-till takeaway or café, five of those seven can be done before the box is sealed, which is why a preconfigured system arrives needing only power, a router and a table. Installation elsewhere typically costs £0–£300 and is often charged separately from the hardware. On-site engineering earns its fee at large multi-station sites with structured cabling, not at a counter with one till and one kitchen printer. Posso ships systems preconfigured with the menu built, and prices on-site installation for larger sites on application.
Key takeaways
- Most of an EPOS installation is configuration that can be finished before the hardware ships.
- You still supply power, a working router or LAN and a mounting position for every device.
- On-site engineers are justified at multi-station sites with structured cabling, not single-till counters.
- Installation is typically £0–£300 elsewhere; check whether the quote includes the menu build.
Takeaway: Ask what arrives already configured, because that list decides whether installation is an afternoon or an invoice.
Why installation is the quiet cost in an EPOS quote
Operators compare till prices to the pound and then discover that the hardware was never the risky part. The risky part is the two weeks between the box arriving and the first clean Friday night, when a kitchen printer is cutting tickets for the wrong station, the card terminal is asking for an amount to be typed in by hand and the menu still has the old prices on it.
The common mistake is to treat installation as a physical job, like fitting a sink. It is mostly a data job. Building a 180-line menu with modifiers, allergens and two VAT treatments takes longer than everything else combined, and it is the part most often left to the operator with a login and a PDF manual.
The other mistake is at the opposite end. A large restaurant with four tills, three kitchen stations, a bar and a pass needs network cable run to places a Wi-Fi signal does not reliably reach, and that is a genuine on-site job with a cost. The guide below separates the two cases. If you are moving from an existing till, the switching EPOS system hub covers what transfers and what does not.
What an installation actually involves
Seven jobs, in the order a competent installer does them. Ask any provider which of these happen before shipping and which happen at your counter.
Build the menu before the hardware ships, not after
A menu build is every item, every modifier and every price, with VAT treatment set per item and allergens marked against the 14 EU categories. A kebab shop with 60 items, five sizes and twelve sauces is close to 300 lines once modifiers are counted. Done properly it takes a working day; done from a laminated menu photographed on a phone it takes two and still needs correcting. Send the provider your menu, prices and service charge rule in week one, and the till arrives knowing what a large doner with extra chilli costs.
Pair every printer to a station, then test with a real order
A kitchen printer is paired to the till over the network or USB and then told which categories to print. The job is not the pairing; it is the routing. Drinks to the bar, mains to the grill, desserts to the pass, and the receipt printer at the counter only. The test is to ring a mixed order, a lager, a 12-inch pizza and a tiramisu, and watch where the three tickets land. Preconfigured, this test takes two minutes on arrival; otherwise budget an evening.
Let the drawer fire from the till, never from a key
The cash drawer connects through the receipt printer and opens when a cash sale completes. Set up wrong, staff leave it unlocked and open all shift, and your cash variance reporting is fiction. Set up right, it opens for cash, stays shut for card and logs who opened it with a no-sale. The pairing is a single cable and a setting; the discipline it enforces is worth more than the drawer. Ask whether the drawer arrives already connected to the printer.
Pair the card terminal so nobody types an amount
An integrated terminal receives the total from the till; an unintegrated one has a member of staff key £24.85 into it, and on a Friday that becomes £42.85 often enough to matter. Pairing is done over the local network or the provider's cloud and should be finished before shipping where the terminal is supplied with the till. Where you keep an existing Teya or Dojo machine, pairing happens on arrival and takes minutes with support on the phone.
Give the till a network it does not have to share
A single till, one kitchen printer and a card terminal will run happily on a decent router. The problem is the router already serving the shop Wi-Fi, two phones streaming music and a delivery tablet. Plug the till into the router by cable if you can, keep the printer on the same network, and reserve the terminal's address so it does not move. An offline-first till keeps trading if the broadband drops, but the printer and terminal still need the local network, so do not buy the router cheap.
Train the people who open and close, not just the owner
Training that only reaches the owner fails on the first shift the owner is not there. The essentials are ringing an order with a modifier, applying a discount, voiding a line before and after sending to the kitchen, a refund, cashing up and reading a Z report. That is forty minutes with a till that already has your menu on it. Do it with the two people who actually run service and keep the support number by the till.
Pre-arrival checklist: what you do before the box lands
A preconfigured shipment removes the configuration. It does not remove the building. These are the operator's jobs.
Power where the till and printers will live
A touchscreen terminal, receipt printer, kitchen printer and card terminal charger need four sockets between them, in two locations. Count the sockets at the counter and the pass, and avoid a daisy chain of extension leads behind a fryer.
Router, cable and a signal that reaches the kitchen
Confirm your broadband is live before the delivery date, not the day of. Run one Ethernet cable from the router to the counter if the distance allows. If the kitchen printer is more than a brick wall away from the router, test the Wi-Fi signal where it will sit with a phone first. A cheap access point beats a week of missing tickets.
A clear counter position and a mounting plan
The terminal needs flat space, a clear line of sight for the customer display if you have one, and the card terminal within the customer's reach. Wall or pole mounts for kiosks and kitchen screens need a stud or a bracket, and that is a drill and a spirit level, which no remote installer can do for you. Decide the position before the box arrives so you are not rearranging a counter during a lunch service.
Your menu, prices and rules sent in writing
The menu build can only be as good as what you send. Current menu with prices, eat-in versus takeaway differences, any service charge rule, meal deals and their components, and allergens per dish. Send it as a spreadsheet or a clear PDF a fortnight ahead and the first order you ring on arrival will be right.

Ranges are typical UK figures at October 2026; Posso prices are published on EPOS pricing.
What to ask a provider before you sign
What arrives already configured, and what do I configure myself?
Get the list in writing: menu built, printers routed, drawer paired, card terminal paired, user accounts created. If any of those are your job, ask how long each takes a first-time user and who you call when the kitchen printer prints the receipt and the receipt printer prints the kebabs.
Is on-site installation included, and if not, what does it cost?
Many quotes bundle a visit into a monthly fee or charge per site. Ask for the on-site price as a separate line, and ask what triggers it. A single till in a 40-cover café almost never needs an engineer; a four-till, three-station restaurant with new cabling usually does. Posso prices on-site installation for larger sites on application, and setup for a standard system is free, so you should see a clear line for each.
What happens if the internet goes down on day one?
An installation that only works with live broadband will fail on a Saturday when the line drops. Ask whether the till runs from a local database, whether orders still print to the kitchen over the local network, and whether card payments have a fallback. An offline-first system with the printer on the same router keeps serving; a browser-based till does not.
The Posso approach to EPOS installation
Posso systems arrive preconfigured. The £499 + VAT system includes the touchscreen terminal running Windows 11 Pro, a kitchen printer, a receipt printer, a cash drawer, the menu build and staff training. The menu is loaded, the printers are routed to the stations you told us about and the drawer is connected before the box is sealed, so what remains at your end is power, your router and a counter to put it on.
The till runs an offline-first local database, so a dropped broadband line does not stop service, and kitchen tickets keep printing over your local network. Card payments run through Posso Pay from 1% + 10p, quoted on card turnover and the same rate in store and online, with the terminal paired to the till so the amount is pushed rather than typed. Sites that already have a Teya or Dojo terminal can keep it and pair it on arrival.
Training is included and done remotely with your menu on screen, and support runs Monday to Friday, 9am–9:30pm from Leicester, with an urgent out-of-hours line for till-down issues. You own the hardware outright; software is from £25 + VAT a month.
Setup (menu build + configuration) is free; on-site installation for larger sites is priced on application. Systems are preconfigured and shipped plug-and-play.
Where to look elsewhere
If your site is a large hotel or a multi-floor venue with structured cabling to be designed, a dedicated AV and network contractor should run the cable and a hospitality EPOS should sit on top of it.
If you are a sole trader at a market stall taking twenty payments a day, a card reader with a simple app has no installation at all, and that is the right amount of installation for the job. A full EPOS, from anyone, solves a problem you do not yet have. Retail businesses with barcoded stock need a retail platform with purchasing and stock control, which is not what Posso builds.

EPOS system installation — frequently asked questions
How much does EPOS installation cost in the UK?
Installation elsewhere typically costs £0–£300, and the menu build is often charged separately or left to the operator. Posso includes the menu build, configuration and training in the £499 + VAT system price, ships the system preconfigured, and prices on-site installation for larger sites on application. Ask any provider for installation, menu build and training as three separate lines so you can see what is actually included.
How long does an EPOS installation take?
It depends on how much arrives configured. The menu build is the longest job, typically a working day for a full takeaway or restaurant menu, and it should be done before the hardware ships. Printer, drawer and card terminal pairing are minutes each when preconfigured. Systems are preconfigured and shipped plug-and-play. For a large multi-station site with new cabling, plan the network work with the provider before agreeing a date.
Can I install an EPOS system myself?
For a single till with one kitchen printer, yes, provided the system arrives preconfigured. You plug in power, connect the terminal to your router, place the printers and ring a test order. What you should not attempt yourself is a menu build from scratch on a system you have never used, or network cabling across a large site.
Do I need an engineer to install my EPOS?
Rarely for a counter with one till, a kitchen printer and a card terminal. An engineer is justified at sites with several tills, multiple kitchen stations, a separate bar and cable that needs running through walls or ceilings, and at sites being fitted out from a shell.
Does EPOS installation include the menu build?
Not always, and it is the question that separates quotes. Some providers charge for the build by the hour, some hand you a login and a guide, and some include it. Posso includes the menu build and loads it before shipping. Whoever does it, send the menu with prices, eat-in and takeaway differences and allergens, because the build is only as accurate as what the provider is given.
What do I need to have ready before my EPOS arrives?
Live broadband and a router, with an Ethernet cable to the counter if possible. Enough sockets at the counter and the pass. A flat, clear counter position and any wall or pole mounts fitted. Your menu, prices, VAT treatments and allergens sent to the provider in writing a fortnight ahead. An opening float, a cashing-up routine and two named staff booked for training on arrival day.
