Frequently asked questions

Before you request a quote

These answers help visitors decide whether a new installation, repair or replacement is likely to be the right route.

Do you install both audio and video intercom systems?

Yes, use the enquiry form to describe the property and the type of entry system you are considering. We can then discuss the most suitable approach for your requirements.

Can you repair an intercom installed by another company?

Use the repair option in the form and tell us what is not working. Include the system brand or a photo of the handset or entrance panel if you know it, as this can help with initial assessment.

Do you work with flats and communal entrances?

The form includes options for individual flats, apartment blocks and commercial premises. For shared entrances, tell us the approximate number of units affected and who can authorise the work.

Can an old intercom be upgraded?

Many older systems can be assessed for repair, replacement or upgrade. Tell us what system is currently installed and what you would like to improve, such as video, door release or access options.

What information should I include in my request?

The most helpful details are the property type, postcode, whether you need installation or repair, a short description of the issue or project, and an optional photo where relevant.
