Door Entry Systems — Comelit, BPT & Videx intercoms for flats, offices and gated sites

We install audio and video door entry systems from Comelit, BPT, Videx, and 2N for blocks of flats, offices, care homes, and gated developments across Bedfordshire, Hertfordshire, and London. Whether you need a simple two-wire audio system for a six-flat conversion or a full IP video intercom with smartphone answering for a 100-unit development, we handle the design, installation, and aftercare.

Who is this for?

For landlords, property managers, housing associations, and developers who need a reliable way for residents or staff to screen visitors and control access to their building — without buzzing in every delivery driver blindly.

  • Blocks of flats and apartment buildings (new build and retrofit)
  • HMO conversions and shared houses
  • Office buildings and serviced offices
  • Care homes and sheltered housing schemes
  • Gated residential developments and estates
  • Schools, nurseries, and colleges
  • Multi-tenant commercial buildings
  • Medical practices and dental surgeries

Door entry problems we fix every week

  • No intercom at all — residents have to come downstairs or buzz people in blind without knowing who's at the door
  • An old BT or Entryphone system from the 1990s that crackles, cuts out, or doesn't release the lock half the time
  • Audio-only intercom with no camera — residents can't see who they're letting in, which is a safeguarding risk
  • Tailgating through communal doors because the door closer is broken or the lock doesn't engage properly
  • No smartphone integration — residents can't let in deliveries or visitors when they're away from their flat
  • The developer or previous installer has gone bust and nobody can source parts or add new handsets

What's included in our door entry installations

External Entry Panel

Vandal-resistant flush or surface-mount panel from Comelit, BPT, Videx, or 2N. Available with call buttons for individual flats, a scrolling name directory, or keypad with code entry. Video panels include a wide-angle camera with night vision.

Indoor Handsets or Monitors

Audio handsets or colour video monitors for each flat or office. Comelit Icona and BPT Agata monitors provide a live camera feed, two-way speech, and door release at the touch of a button.

Electric Lock & Door Hardware

Electric strike, fail-safe maglock, or electric deadlatch on the communal entrance door — properly installed with an overhead door closer so the door actually shuts and locks behind people.

Professional Cabling

Comelit Simplebus and BPT two-wire systems minimise cabling — ideal for retrofit in existing buildings. For new builds, we install structured cabling with proper containment through risers and ceiling voids.

Access Credentials

Optional proximity fob or smart card entry for residents who need keyless access without using the intercom. Compatible with Paxton access control if you want a unified system.

Smartphone App Answering

2N IP Verso and Comelit systems support call forwarding to smartphones via the 2N Mobile Video app or Comelit app — residents can see who's at the door and release the lock from anywhere.

How it works

01

Building Survey

We visit the site, count entry points and units, check existing cabling, and assess whether a retrofit or new installation is needed. We also check the communal door, frame, and closer — because the best intercom in the world is useless if the door doesn't shut.

02

System Specification

We recommend the right manufacturer and model based on the number of units, building type, budget, and whether you need audio-only, video, or IP with smartphone access.

03

Installation

Our engineers install external panels, indoor handsets/monitors, electric locks, and cabling. We work flat-by-flat to minimise disruption to residents and coordinate access where needed.

04

Testing & Commissioning

Every handset is tested for call quality, video clarity, and door release. We check the electric lock engagement, door closer operation, and smartphone forwarding if applicable.

05

Handover & Aftercare

We hand over documentation to the building manager or landlord, demonstrate the system to residents, and provide ongoing maintenance support. Replacement handsets and spare fobs are available on short lead times.

Frequently asked questions

Which door entry brands do you install?
We install Comelit, BPT, Videx, and 2N. Comelit and BPT are our go-to for blocks of flats — they're reliable, well-supported in the UK, and the two-wire cabling keeps installation costs down. 2N IP Verso is our choice for high-end IP video systems with smartphone integration. Videx is a solid option for audio-only systems on a budget.
Can you replace an old intercom system?
Yes, this is one of the most common jobs we do. We regularly rip out old Entryphone, BT, and obsolete Comelit systems and replace them with modern panels and handsets. If the existing cabling is in good condition, we can often reuse it with a compatible two-wire system to reduce costs.
Can residents answer the intercom from their phone?
Yes. 2N IP Verso systems forward video calls to the 2N Mobile Video app over the internet. Comelit also offers app-based call answering on their IP range. This means residents can see who's at the door and release the lock even when they're at work or on holiday — great for letting in deliveries.
What's the difference between audio and video intercoms?
Audio intercoms let you hear the visitor and speak to them before releasing the door. Video intercoms add a camera so you can see who's there on a colour monitor or your phone. We always recommend video for blocks of flats — the cost difference is relatively small and the security benefit is significant, especially for vulnerable residents.
Can you install intercoms in existing buildings without major building work?
Yes. Two-wire systems like Comelit Simplebus and BPT require only a single pair of cables from the panel to each handset, which drastically reduces the amount of cabling needed compared to older multi-core systems. We route cables through existing risers, trunking, and ceiling voids wherever possible.
Do you install gate automation and entry systems for gated sites?
Yes. We install automated swing and sliding gates with intercom integration, so visitors call through the intercom panel and residents can release the gate remotely. We use CAME and BFT gate automation kits and can integrate with fob access control and ANPR for vehicle entry.
How much does a door entry system cost?
A basic audio system for a small block of 6-8 flats typically starts from around £1,200 fitted. Video systems with colour monitors start from around £1,800 for a similar size block. IP systems with smartphone access cost more but offer significantly better features. We provide an itemised quote after the survey.
What maintenance does a door entry system need?
The main maintenance items are the electric lock (which wears over time from daily use), the door closer (which needs adjusting seasonally), and cleaning the camera lens on the external panel. We offer annual maintenance visits to check all components and replace any worn parts before they fail.
