Cisco Routers — ISR, Catalyst 8000 and Branch WAN Supplier

Overview

Cisco Routers — ISR, Catalyst 8000 and Branch WAN Supplier

We supply Cisco branch and edge routers for sites that need more than a broadband box — dual circuits, VPN back to head office, SD-WAN policy or a 5G failover path. We size on the WAN bandwidth and the services running over it, not the interface count.

UK buying guide

Before You Buy Cisco for a UK Site

Compare the exact hardware, licensing and compatibility—not just the product family or headline price.

WAN interfaces first

Match the router to your internet hand-off, required Ethernet or fibre interfaces, branch topology and failover requirement. Verify interface availability in the exact SKU, not just the router series.

Throughput with your features enabled

Check the model documentation for the performance and entitlements required by your routing, VPN and security configuration. The internet circuit speed alone does not establish which router is suitable.

Existing-estate compatibility

For an expansion, include existing router models, software versions and management requirements. Check lifecycle notices before specifying a legacy series for a new UK site.

What to include in your UK quote request

  • Exact model or part number, quantity and whether this is a new site, expansion or replacement.
  • UK installation postcode, required date and any existing equipment or management platform.
  • Required licence and support term, compatible power supplies, optics, mounting kits and UK power leads where applicable.
  • Request an itemised quotation showing hardware, licences, support, delivery and VAT treatment; confirm availability and lead time before ordering.

Cisco Router Models We Quote Most

Branch routing splits by throughput and by whether you want classic IOS-XE routing or SD-WAN. We quote both paths and explain the licensing difference before you commit.

  • ISR 1100 series — small branches, integrated LTE/5G options, fanless
  • ISR 4000 series — mainstream branch routing with voice, security and WAN modules
  • Catalyst 8200 / 8300 — modern branch edge with SD-WAN and cloud on-ramp
  • Catalyst 8500 — regional hub and data-centre WAN aggregation

Dual Circuits, VPN and 5G Backup

Most router enquiries we take are really resilience enquiries. We design the WAN so a failed circuit is a non-event — dual providers, automatic failover, and policy that keeps voice and line-of-business traffic on the healthier path.

  • Dual-WAN failover with fibre, broadband and 5G backup
  • Site-to-site and remote-access VPN terminated on the router
  • SD-WAN policy for voice, Teams and business applications
  • Cellular modules and antennas quoted with the router

Licensing and Support Without Surprises

Cisco routing licences are where budgets slip. We set out the DNA tier, the term and the renewal date in writing, and co-terminate multi-site estates so everything lands on one anniversary.

  • DNA Essentials and Advantage explained against what you actually use
  • SmartNet support tiers with defined replacement terms
  • Co-terminated renewals across branch estates

FAQs

Questions We Are Asked Most

Which Cisco router suits a small branch office?

An ISR 1100 covers most small branches, with an LTE or 5G variant if you want cellular backup built in. If the site runs voice gateways or several service modules, an ISR 4000 is the better fit.

Should I buy an ISR or move to Catalyst 8000 SD-WAN?

If you are managing a handful of sites with static routing and VPN, an ISR is simpler and cheaper. Once you have multiple circuits per site or a dozen-plus branches, Catalyst 8000 with SD-WAN pays for itself in central policy control.

Can you configure the router before delivery?

Yes. We pre-stage interfaces, routing, NAT, VPN tunnels and QoS, then ship it ready to connect, with the running configuration documented for your team.
