A business intercom system costs £400 to £4,000 per entrance installed in the UK. A simple audio intercom for one office door sits at the lower end, while a video or IP intercom that rings reception and staff mobiles, with fob or code entry built in, sits at the top. For shared office buildings, the cost depends on how many businesses or floors need their own call button and answering point.
Key Takeaways
- Audio intercoms for a single office entrance cost £400-£1,000 installed
- Video intercoms with a reception screen typically cost £800-£2,500 per entrance
- IP intercoms that call staff phones and work with access control cost £1,500-£4,000
- Shared buildings need a call button and answering point for each tenant or floor
- Combining intercom and fob entry on one door avoids paying for two systems

What Does a Business Intercom Cost?
A business intercom typically costs £400 to £4,000 per entrance installed. The answering method is the biggest factor: a handset on one desk is the cheapest option, while systems that ring several screens, reception and staff mobile phones cost more.
| System type | Best for | Typical installed cost per entrance |
|---|---|---|
| Audio intercom | Small office, staff entrance | £400-£1,000 |
| Video intercom with reception screen | Offices with a reception desk | £800-£2,500 |
| IP / app intercom | Calls staff phones, remote door release | £1,500-£4,000 |
| Intercom with built-in fob or code entry | Staff and visitor entry on one panel | £1,200-£3,500 |
Which Intercom Suits Which Business?
The right system depends on who answers the door and when. A small office with someone always at a desk can use a simple video intercom. A business where staff are often away from their desks, or the door must be answered out of hours, benefits from an IP intercom that calls mobile phones.
- Offices with reception: a video intercom with one main screen, plus extra screens for a back office if needed.
- Warehouses and trade counters: a vandal-resistant panel at the gate or goods-in door, calling a screen in the office and staff phones.
- Clinics and salons: video intercom with timed door release so staff can let clients in without leaving a treatment room.
- Shared office buildings: a multi-button or digital directory panel, with a screen or handset for each tenant.
For gates and car parks, cable distance often matters more than the panel itself. Our gate intercom systems page explains the options.
How Much Does Door Entry Cost for a Shared Office Building?
For a shared office building, door entry typically costs £300 to £600 per tenant or floor, plus the entrance panel and lock. A building with four businesses usually comes to £2,000 to £4,500, depending on audio or video and whether existing cabling can be reused. The cost is normally covered by the landlord or through the service charge.
| Building | Audio system | Video system |
|---|---|---|
| 2-4 tenants | £1,500-£3,000 | £2,000-£4,500 |
| 5-10 tenants | £2,500-£5,000 | £4,000-£8,000 |
| 10+ tenants or several entrances | £4,500+ | £7,000+ |
Can a Business Intercom Work With Access Control?
Yes, and it usually saves money. Staff use a fob, card or phone to open the door, and visitors press the intercom. Both share the same lock, power supply and cabling. Many modern panels from Hikvision, Comelit and Paxton include a built-in fob reader or keypad. See our access control cost guide for per-door prices.
What Door Hardware Does a Business Intercom Need?
An intercom needs a way to release the door. Many commercial doors already have a suitable lock; older or heavy doors may need one fitted.
| Item | Typical installed cost |
|---|---|
| Electric strike in the frame | £150-£300 |
| Magnetic lock with exit button | £200-£400 |
| Emergency break-glass release | £40-£80 |
| Door closer | £100-£200 |
Doors on escape routes must always open safely in an emergency. Magnetic locks are fitted with an emergency release and are normally linked to the fire alarm so they release automatically.
Are There Monthly Fees for Business Intercoms?
Traditional wired audio and video intercoms have no monthly fees. Some app-based and cloud-managed intercoms charge a subscription, often per user or per door, and 4G intercoms need a SIM, typically £5 to £15 a month. It is worth asking about ongoing costs before choosing a brand, because they can outweigh the difference in installation price over a few years.
How Long Does a Business Intercom Installation Take?
A single-entrance office intercom is usually installed in half a day to one day. Shared buildings and systems combined with access control typically take one to three days. Installation can be arranged early or late so the entrance stays usable during working hours.
