Survey the existing system
We identify the panel, handset type, power supplies, cable topology, release hardware and how many flats or entrances are affected.

Replacing an old communal intercom system
A structured replacement plan for obsolete panels, unreliable wiring, repeated handset faults and shared entrances that no longer meet the building’s needs.

Choose the right level of upgrade
Audio remains cost-effective where identification by voice is enough. Video is useful where residents need visual confirmation. Fob access can reduce uncontrolled key copying.
Plan resident access
The quote should explain access requirements, likely disruption, temporary arrangements, testing and handover rather than treating a block like a single front door.
Questions before you enquire
Common questions
Can existing cables be reused?
Sometimes. Cable condition, topology and the chosen system decide whether reuse is sensible. Reusing unsuitable cable can turn a new system into an unreliable one.
Do all flats need to be accessed?
Usually each handset must be installed or tested. The work can often be phased, but missed flats should be planned rather than left undocumented.

Send the scope, not a perfect specification
We need enough information to choose the right route. The exact product can follow after the building, fault and access requirements are understood.
