Line Assurance: helping you stay connected to your customers

We have never been more dependent on our telephone lines than we are now. Face-to-face communication is becoming less frequent, and any loss of service can cost thousands of pounds in lost time and business. Worse, many small businesses have their broadband service on the same line as their voice, so losing one can completely hinder your business.

However, many of us still don’t have any real disaster recovery plans in place. We have little idea what we might do if the service goes down or how much it might cost to reconnect, or how long it might take. Line assurance gives you the peace of mind to know that, if a fault happens, you have someone to help.

As an additional benefit, we will also provide you with a free installation of the latest full-fibre products and services when they become available in your area, even if you don’t have your broadband with us. Allowing you to take full advantage of the extra speed and reliability these products will provide without worrying about install fees.

How you stay connected at all times

Free Upgrades to Ultrafast Fibre

If FTTP or another Next Gen service (SOGFast, SOGEA etc) becomes available we will upgrade your line to the new service FOC. Line speed will be at our discretion, but you can upgrade to faster speeds for an increment on your monthly bill. Discounts may be available should you wish to enter into a new contract. A router will be provided as part of the upgrade.


No Engineering Charges

 In the event of a Line fault we will cover all BT Openreach engineering charges (in hours and out of hours) as long as you run through the required checks before we send out an engineer.


Disaster Recovery Included

We will provide a replacement broadband router within 2 working days if yours fails, a 4g router and sim card if a broadband fault persists for more than 2 working days, and the Chess Divert service without set up charges or the Chess Divert+ free of charge for 1 month in any calendar year in the event you cannot receive calls to the line we provide.*
