Key takeaways
Multi-site connectivity is about connecting several locations reliably, not just buying broadband at each site.
Different sites may need different connection types.
Critical sites may need leased lines or DIA.
Smaller branches may only need FTTP or business broadband.
Retail, hospitality and care sites often benefit from 4G or 5G backup.
SD-WAN can help manage traffic, failover and cloud app performance across sites.
Managed WAN is useful if you want a provider to monitor, support and manage the network.
MPLS can still be useful for private or latency-sensitive traffic, but many businesses now compare SD-WAN or hybrid WAN.
Cloud-heavy businesses need to think about Microsoft 365, hosted desktops, VoIP and SaaS routing.
The best quote should show site-by-site costs, resilience, support, security and total monthly spend.
What is multi-site connectivity? Multi-site connectivity is the network setup that connects two or more business locations, and can connect:
head office to branches
retail stores to central systems
depots to stock platforms
care homes to cloud records
restaurants to booking systems
hotels to EPOS and guest Wi-Fi
warehouses to logistics systems
offices to hosted desktops
clinics to secure applications
franchises to central operations
remote staff to business systems
A simple business may only need separate broadband connections at each site whereas a more complex business may need WAN, SD-WAN, managed WAN, leased lines, cloud connectivity, 4G/5G backup and secure access.
Multi-site connectivity vs business broadband Business broadband is only one possible part of a multi-site network.

Multi-site connectivity options 1. Business broadband or FTTP at each site
This is the simplest setup – each site has its own business broadband or full fibre connection.
Best for:
small branches
low-risk sites
independent locations
sites using cloud apps but no major site-to-site traffic
businesses keeping costs low
Watch out for:
inconsistent speeds
weaker repair targets
no central control
no built-in failover
separate contracts
separate support routes
poor upload speeds on some services
2. Leased line or DIA at critical sites
A leased line, also called dedicated internet access or DIA, gives a site a dedicated business connection.
Best for:
head offices
call centres
warehouses
care homes
hotels
manufacturing sites
high-traffic offices
hosted desktop users
VoIP-heavy teams
sites where downtime affects revenue or service delivery
This does not mean every site needs a leased line – a common design is:
leased line at head office
leased line or DIA at critical sites
FTTP or business broadband at smaller branches
4G/5G backup where downtime matters
If you already know your business needs dedicated connectivity across several locations, see our dedicated guide: Multi-Site Leased Lines UK
3. SD-WAN for multiple sites
SD-WAN is often a strong fit for multi-site businesses as it help manage traffic across:
broadband
FTTP
leased lines
DIA
MPLS
4G/5G
cloud connectivity
SD-WAN can help with:
central management
application prioritisation
failover
cloud routing
traffic visibility
branch consistency
faster site rollout
lower MPLS dependency
VoIP and video performance
payment traffic priority
For the main SD-WAN page, see:
SD-WAN Providers UK
4. Managed WAN for multiple sites
Managed WAN is useful when you want a provider to manage the network for you, and your provider might handle:
network design
site connectivity
routers
firewalls
broadband
leased lines
MPLS
SD-WAN
monitoring
reporting
support tickets
provider escalation
security coordination
change requests
new site rollout
This can be useful if you have several sites but limited internal IT resource.

retail stores
restaurants
hotels
care homes
clinics
garages
branches taking card payments
sites using booking systems
sites relying on cloud tills or EPOS
locations with limited fixed-line options
8. Cloud connectivity across multiple sites
