Access control system cost: the nine things that set the price
Updated
Ask three installers for a price on the same building and you can get three very different numbers. Almost always it is because they have assumed different things about your doors.
Why we do not publish a price per door
Because there is not one. A single door on a standalone keypad and a single door on a networked system with a motorised lock, a fire interface and a cloud subscription are the same line on a spreadsheet and nothing like the same job. Anyone quoting you a national average per door is either guessing or has already decided what to sell you. What is worth knowing is the list of things that move the number, so you can read a quote properly.
The three architecture choices
- Standalone
- Each door stands on its own, programmed at the door. Cheapest to install, no ongoing fees, and it becomes painful the moment someone loses a fob or you need to know who went where. Sensible for one or two doors.
- Networked (on-premises)
- Controllers wired back to a server or PC you own, with management software. Higher installation cost, no subscription, and you own the hardware and the maintenance risk.
- Cloud hosted
- Controllers talk to a hosted platform, managed from a browser or phone. Less on-site kit, easier multi-site management, and a recurring per-door or per-user subscription that runs for as long as you use it.
The honest comparison between them is a five-year total, including subscription, software support, credential costs and maintenance visits. A cloud system that looks cheaper on day one can be dearer by year four, and an on-premises system carries the cost of the server refresh nobody budgeted for.
The door is the job
The most common reason a quote grows after survey is the doors themselves. Controlling a door means it must close, latch and seal reliably every time, and a lot of commercial doors do not. Warped leaves, dropped hinges, missing or failed closers, frames that were never square: all of that has to be sorted before an access control system will behave. Get a door-by-door survey before you accept any price, and ask specifically whether remedial joinery is included or excluded.
What to ask every installer for
- A per-door breakdown: reader, lock type, exit device, cabling, and any door remedial work.
- The five-year cost including subscriptions, licences, support and planned maintenance.
- Who owns the credentials and the data, and what a replacement fob or card costs.
- Whether the price includes the fire alarm interface and who signs it off.
- What the response time is when a door fails, and whether that is in the maintenance price or extra.
- Whether the system is open or proprietary: can another company maintain it, or are you locked to them?
One thing worth deciding early: do you actually need audit trails and time-based access, or just a way of not cutting keys? The answer changes the architecture, and the architecture drives most of the price.
Credential costs after the install
Fobs and cards get lost, and replacements are a real line in the running cost of a busy site. Mobile credentials remove that, at the cost of a per-user licence and a policy for people who will not install an app on a personal phone. Biometrics remove the credential entirely but bring you into processing biometric data, which is special category personal data under UK data protection law and needs its own assessment. See fobs, cards, mobile or biometric.
