What does commercial door entry work involve?
Commercial door entry work usually involves a site survey, a written design, installation and commissioning, handover documents, and ongoing servicing under a maintenance contract. The sections below explain what that means in practice.
A door entry system puts a call panel at the entrance and a handset, monitor or phone app inside. A visitor presses the button, staff or residents see or speak to them, then release the door or gate remotely. It is the visitor side of building security, while access control handles staff and residents who come and go.
Audio systems suit simple entrances. Video systems show the caller and can record images. IP and app-based systems let reception, a security desk or an off-site manager answer calls from anywhere, and many combine a fob reader in the same panel.
Shared buildings such as business centres, flats and student housing need a panel button for each unit and a trades or fire override. The entrance should stay usable for disabled visitors, in line with Part M of the Building Regulations.
If a video system records visitors, that footage is personal data under UK GDPR, so the same rules as CCTV apply.
How much does commercial door entry cost?
Commercial door entry costs from £200 for a entry panel with fob reader (per door) up to £1,700 for a single entrance (audio or video system).
| Work | From | To | Notes |
|---|---|---|---|
| Single entrance, audio or video system | £400 | £1,700 | Installed, published averages £677 to £1,011 |
| Entry panel with fob reader, per door | £200 | £500 | Equipment for a combined panel |
| Biometric entry, per door | £500 | £1,000 | Fingerprint or face readers |
Typical ranges for commercial work. Always get a written quote after a site survey.
What do I need to check before buying?
- Certification: door entry is not always within NSI or SSAIB scope, so ask what the company's certificate covers.
- Audio or video: do you need to see callers, and should images be recorded?
- Remote answering: can calls go to reception, mobiles or a security desk, and are app fees monthly?
- Fire and trades: will the door release when the fire alarm sounds, and is there a timed trades button?
- Accessibility: is the panel at a usable height with clear contrast, and does it support hearing loops?
- Upgrades: can they reuse existing cables, and will the system take a fob reader later?
Common questions about commercial door entry companies
How much does a commercial door entry system cost?
A single entrance audio or video system usually costs £400 to £1,700 installed, with published averages of £677 to £1,011. Combined panels with a fob reader cost £200 to £500 per door for equipment. Multi-occupancy buildings are priced after a survey of units and cable routes.
What is the difference between door entry and access control?
Door entry lets you see or speak to a visitor and let them in remotely. Access control lets known users open doors with a fob, card, code or phone, and records who went where. Many buildings use both, often in one panel at the main entrance.
Can I answer the door entry system on my phone?
Most IP and app-based systems send calls to smartphones as well as to indoor monitors. That suits small offices without reception and managers who cover several sites. Check whether the app needs a monthly licence and how many users it allows.
Do I need to follow GDPR if my door entry records video?
Yes. If a video system records visitors at business premises, the images are personal data under UK GDPR. You need a clear reason to record, a sign at the entrance, a set retention period and controls on who can view the footage.
Can a door entry system be upgraded without rewiring?
Often, yes. Many manufacturers make two-wire or IP systems that reuse existing cables, which keeps cost and disruption down. An installer will test the cables on a survey and tell you which panels and handsets can be replaced without new cabling.
