The end is coming for your traditional landline

Are you ready for the switch off?

When you consider that 16 million lines and channels will need to be migrated to alternative products it’s worth starting to look at other options sooner rather than later.

What People Say

Hutton Wandesley Estates

Rural Business Park
As many of our commercial tenants are from the creative sector, having access to superfast broadband is vital to our business offering. We have struggled with the service that the national ISPs were supplying. Working with Signa Technologies and Deep Blue have enabled us to put in place the service we wanted to provide.

Home Instead Senior Care

Providers of professional, compassionate care at home.

Two new phones arrived yesterday. Thank you and can we have one more please? We are growing faster than we realised!


Bespoke Home Cinemas
Working all over the UK, we needed a solution that connected our on-the-road engineers with the office. Deep Blue has tailored a solution that delivers on all levels. From our initial consultation to the extremely efficient after-care service, we know that we are in safe hands and so glad that we made the move.

Old Gipton Fire Station

Recycling at it's best - from Fire Station to Office Block. Deep Blue are proud to be supplying comms to the old Gipton Fire Station. The site has been transformed into a multipurpose community hub, providing a base for six local charities, along with rooms available to hire, a cookery school and a café for all of the community to enjoy


Live For Today
Live For Today offer exciting adrenaline fueled activities for all ages. With 4 venues across the UK we needed a phone service that could connect these together. The service offered is excellent and the response time to answer queries is always super fast. We are a very happy client.
