Sale High School Case Study

Telephone Systems, Lockdown and Broadband

How Tel Group worked with Sale High School to improve their communications, connectivity and safety across the school.


Sale High School is a large secondary school located in Greater Manchester. They aim to be the school of choice for their community where every child succeeds.


Sale High School wanted to move away from their restricting analogue telephone system and were also looking at ways to enhance their school safety in the event of an intruder lockdown.

They were familiar with Tel Group after meeting at local conferences and decided to chose them as one of their 3 quotes. Tel Group came out on top in terms of price and quality and were selected to fulfil these requirements.


Tel Group visited Sale High School and installed a SIP phone system with 60 extensions and 8 lines, bringing a powerful solution to their communications.

A lockdown intruder system was also installed and integrated into the phone system. This consisted of 42 internal and external speakers, and multiple pre-recorded messages, providing instant communication at a touch of a button.

After working with Tel Group for 3 years, when their broadband came up for renewal they chose Tel Group to honour the upgrade, providing them with a strong, reliable and scalable FTTC connection throughout their entire premises.


Tel Group installed a full telephone and lockdown system for us during Summer. The initial installation was due in April but had to be put back due to lockdown. This left our school in a panic as our other providers had already been given notice to cancel.

Tel Group were amazing in ensuring that, even though we couldn’t have our new systems, our services were uninterrupted.

I knew from this point that we had made the right decision in choosing Tel Group. The installation was seamless and the engineers on site were absolutely fantastic. They were friendly, efficient and really helpful. Any teething problems we had were dealt with effectively and efficiently and I really cannot recommend the team at Tel Group enough!
