In short: School broadband from BT ranges from full fibre (FTTP) for smaller primaries to BTnet, a dedicated leased line of up to 10Gbps, for secondaries and colleges. Trusts can link schools with BT Ethernet Connect. The DfE's standards ask schools to work towards full fibre by 2030, with a backup connection, content filtering and a firewall.
What the DfE broadband internet standard asks for
The Department for Education publishes digital and technology standards for schools and colleges in England. Broadband internet is one of its six core standards, and DfE says schools and colleges should be working towards meeting it by 2030. When we checked it on gov.uk in October 2026, it covered three areas. In summary:
| Standard | What it says, in short |
|---|---|
| Full fibre connection | Use a full fibre connection such as a leased line or FTTP; copper does not meet the standard. Primaries should have at least 100Mbps download and 30Mbps upload; secondaries, all-through schools and FE colleges should have capacity for 1Gbps download and upload. Move as soon as possible, usually at the end of an existing contract or once full fibre is available, and make sure new contracts on other connection types allow a switch to fibre. |
| Backup broadband connection | Have a backup connection of a different type from the main one (DfE's examples are a leased line plus FTTP, or FTTP plus low Earth orbit satellite), multiple routers set up to fail over automatically, and redundant power on core network equipment. |
| IT security and safeguarding | Use content filtering that meets the online safety requirements in Keeping children safe in education, and a firewall, either an on-site device the school manages or an edge service run by the supplier or IT support. |
DfE also points out that real speeds depend on what sits behind the line: internal cabling, switches, routers and wireless access points. Filtering has its own filtering and monitoring core standard.
The standards change from time to time, so always check the current broadband internet core standard on gov.uk before you sign a new contract. We plan school connections around it.
BTnet or full fibre: choosing the main connection
Two BT products line up with the full fibre standard:
- BTnet is BT's dedicated internet leased line, with symmetrical speeds of up to 10Gbps that are not shared with neighbours. BT states a 100% availability SLA, a 5-hour target fix time and latency under 20ms within the UK. It suits secondaries, all-through schools and colleges that need gigabit capacity in both directions.
- BT business full fibre (FTTP) delivers broadband at up to 900Mbps over a shared fibre network. For many primaries it comfortably exceeds the 100Mbps download and 30Mbps upload minimum, at a lower cost than a leased line.
Leased lines take longer to install than broadband and are always subject to a site survey; our leased line installation guide explains the process. Not sure which you need? Read broadband vs leased line.
Backup: a pattern that matches one of the DfE examples is BTnet as the main line with full fibre broadband as the backup, through routers that fail over automatically. Smaller schools on broadband can also add Hybrid Backup, which switches to the EE Business 4G network if the line fails. A 4G backup can keep the office and key systems online, but it is not sized for a whole school's classroom traffic, so check with us whether it is enough to meet the backup standard at your school.
Content filtering and firewalls
Filtering is a safeguarding duty, not just an IT setting. BT offers several layers that can form part of a school's approach:
- BTnet Meraki + BTnet Security adds managed Cisco Meraki equipment to BTnet, with a next-generation layer 7 firewall, advanced malware protection, URL filtering, intrusion detection and prevention, and 24/7 proactive monitoring.
- BT Business Ultra brings a cloud-managed Meraki security device, intrusion detection and prevention, and content filtering that can block more than 70 categories of website to broadband.
- Content Controls on standard BT Business Broadband restrict website categories, although BT ships them switched off, so they must be turned on.
Whatever you use, the school remains responsible for checking that its filtering and monitoring meet Keeping children safe in education. Some schools use a dedicated education filtering service behind the line instead; with BTnet wires only, you bring and manage your own firewall. For firewall options, see Cisco Secure Firewall and Sophos Firewall. Staff training also matters: our sister site covers security awareness training.
Multi-academy trusts and linking schools
Trusts often want every school to share one network, with central filtering, shared servers and one internet breakout. BT has two ways to link sites privately:
- Ethernet Connect gives private point-to-point links at 100Mbps, 1Gbps or 10Gbps, or Ethernet over SoGEA or FTTP for smaller sites, with Diverse and Diverse Plus resilience options.
- SHDS Connect links sites in the same town, city or region, which suits trusts whose schools are close together.
A typical design puts BTnet at a central hub school or data centre, with Ethernet out to each academy. For larger trusts, IP Connect UK and BT Managed SD-WAN are options; see multi-site connectivity.
Wi-Fi across school buildings
Fast fibre is wasted if classrooms have weak Wi-Fi, and DfE has a separate wireless network core standard for it. BTnet Wi-Fi offers up to five Cisco Meraki access points managed from the cloud, which suits a small site or an admin block. Most schools, with several buildings, sports halls and outdoor areas, need a proper wireless design and survey. Our sister company handles Cisco Meraki Wi-Fi projects, and our BT business Wi-Fi page compares BT's options. Keep guest and visitor access on a separate network from staff and pupil devices.
Phones, alarms and the PSTN switch-off
BT Group plans to retire the PSTN by 31 January 2027. Schools often have more on old copper lines than they realise: the main phone system, the intruder and fire alarm diallers, lift emergency lines, door entry and franking machines. Each needs checking and moving to a digital alternative. Read our PSTN switch-off guide, and for alarm lines see alarm and special lines.
For a new school phone system, BT Cloud Voice gives each user their own number and features, and handles busy reception lines with hunt groups and call queues; our sister site explains school phone systems more widely.

Contact usFrequently asked questions
What broadband speed does a school need?
The DfE's broadband standard asks primary schools for at least 100Mbps download and 30Mbps upload, and secondaries, all-through schools and FE colleges for capacity of 1Gbps download and upload, over full fibre. Schools should be working towards this by 2030.
Do schools need a leased line?
Not always. The DfE standard accepts full fibre such as FTTP or a leased line. Larger schools that need symmetrical gigabit speeds and a strong service level often choose BTnet, while many primaries are well served by full fibre broadband.
Do schools need a backup internet connection?
The DfE standard says schools and colleges should have a backup connection of a different type from the main one, with multiple routers set up to fail over automatically and redundant power on core network equipment. DfE's examples are a leased line with FTTP, or FTTP with low Earth orbit satellite.
How can a multi-academy trust connect its schools?
BT Ethernet Connect links schools privately at up to 10Gbps, and SHDS Connect links sites in the same town or region. A trust can run BTnet at a central site, with Ethernet to each school, so filtering and services are managed in one place.
Does the PSTN switch-off affect schools?
Yes. BT Group plans to retire the PSTN by 31 January 2027. Phone systems, alarm diallers, lift lines and door entry on copper lines need moving to digital alternatives, so schools should audit every line well before that date.
