Common faults, and what they usually are

No ring at the handset

Often the handset itself, the wiring to the flat or the call button on the panel.

The door will not release

Usually the lock release or its power supply, or on a maglocked door the exit button, relay or controller that should cut its power.

No picture on the monitor

A camera module in the panel, the monitor, or a power supply that is failing.

Fobs or keypad not working

A reader fault, lost programming or a controller that needs resetting.

Crackling, faint or one-way sound

Often a loose joint in the wiring, damp in the panel or a failing amplifier.

The whole system is dead

Commonly the power supply, a tripped circuit or, in a block, the main controller.

The engineer confirms the actual fault on site in the first hour before any repair.

How much does an intercom repair cost in London?

Ai Protech's repair call-out is a fixed fee: £99 inc. VAT for a standard visit (Monday to Friday, 08:00 to 18:00) or £150 inc. VAT for a priority visit (Monday to Saturday, 08:00 to 19:30). Both include the first hour of diagnosis. If the fix needs parts, more time beyond the first hour or a replacement, the engineer gives you a written price before doing any further work.

Can I book the call-out at night or on a Sunday?

You can book and pay for the call-out online at any time, day or night. Engineers attend Monday to Saturday, 08:00 to 19:30 (no night or Sunday visits), and we confirm the earliest visit within those hours.

Do you repair door entry systems in blocks of flats?

Yes. Entrance panels and face plates, flat handsets and video monitors, fob readers and lock releases can be repaired or replaced: the call-out covers the one-hour diagnostic, and parts, further labour or a replacement are priced in writing before any work. A new or upgraded multi-flat system is surveyed first (Commercial Survey & Spec £199 inc. VAT, credited against the installation) and quoted in writing.

Which intercom makes do you repair?

Paxton, as a platinum registered installer; CAME BPT, as a certified installer; Hikvision video intercoms, with accredited engineers; and FAAC gates and barriers. Other makes too, where parts are still made: tell us what is fitted when you book.

Should I repair or replace my door entry system?

Repair, when the panel and wiring are sound and the fault is a handset, a lock release, a power supply or programming. Replace when parts are no longer made, when the system is audio-only and you want video or answering on your phone, or when a block's handsets are failing one after another. The engineer tells you which after the one-hour diagnostic, with a written price for either route. For a house, a replacement starts at the Video Doorbell Pro, £399 inc. VAT, or Smart Access at £1,799 inc. VAT; for an office, Office Entry starts at £1,199 inc. VAT.

What happens in the first hour?

The engineer tests the panel, the handsets, the lock release and the power supply, finds the fault and tells you what the fix is before doing it. Many faults are a handset, a release or a power supply; anything bigger is priced in writing first.
