Built for business

A Connection Your Team Can Rely On

Business broadband is an internet connection on business terms: a business router, free Openreach installation, an enhanced care level for faster fault fixes and a local team to call.

Fibre broadband in Windsor changes from street to street. An office in the town centre, a home firm in Datchet and a unit on Slough Trading Estate can each get different options, so we check the address and install FTTP or FTTC to suit.

Openreach plans to switch off the old analogue phone network by the end of January 2027, so moving your line to digital now avoids a late rush.

Connection types

Find the Right Broadband for Your Premises

Every building is different. These are the connections we install, depending on what reaches your address in Windsor.

  • Full fibre (FTTP)

    Fibre runs all the way into your building, with packages from 40Mb to 1000Mb. Upload is far higher than on copper, so backups, large files and video calls stop competing.

  • Fibre to the cabinet (FTTC)

    Fibre runs to the green street cabinet and an Openreach copper line covers the last stretch. Our FTTC packages offer up to 40Mb or 80Mb, which suits most small offices.

  • 4G and 5G backup

    A backup router with a mobile SIM takes over when the fixed line fails, so card machines, cloud phones and email stay online until the main line is back.

  • Leased lines

    When your team relies on large uploads or many cloud calls at once, a leased line gives you dedicated bandwidth and equal upload and download.

Local guide

What Broadband Does Your Building Need?

Use this as a starting point. Business internet across Windsor, Slough and Maidenhead varies by building, so we check your address first.

  1. SL4

    Town centre

    Older town centre buildings often bring the line in at the back. We plan it.

  2. SL3

    Home business

    Full fibre in Datchet changes road to road, so we check your house number first.

  3. SL1

    Trading estates

    Units on Slough Trading Estate often share building internet, so we ask about a dedicated line.

  4. SL6

    Maidenhead shops

    Card machines and stock systems on one line need 4G or 5G backup and Wi-Fi in the back room.

What you get

More Than Just a Fast Line

Speed matters, but so does what happens when something goes wrong. Every line comes with setup and support from our engineers, not just a router in a box.

Because we also look after phones and IT for businesses across Windsor and Berkshire, we can tell whether a problem sits with the line, the router or your network.

  • Free business-grade router, configured and secured for you
  • Free activation and Openreach installation, managed by us
  • Enhanced care level for faster fault resolution on your line
  • 4G or 5G backup router that takes over when the fixed line fails
  • Faults raised with the network and chased by us
  • Separate Wi-Fi networks for your staff and your visitors

Getting connected

How to Switch Your Business Broadband

Moving provider should not mean days offline. We plan each step so your Windsor business stays connected throughout.

  1. Check your address

    You send your address and building name, and we check which networks and connection types reach your premises before we recommend.

  2. Pick the right package

    We match a package from 40Mb to 1000Mb to your team size, add backup only where it helps and send a written quote with monthly pricing.

  3. Install and set up

    We book the network engineer, configure your router, firewall and Wi-Fi, and test every device before handing over.

  4. Monitor and support

    If a fault appears, you call our Windsor team, not a national helpline. We raise it with the network and chase it.

Choosing a provider

What to Look For in a Business Internet Provider

Here is what we have learned from setting up lines for offices, shops and home businesses in Windsor, Eton and Slough, so you can compare broadband deals before you sign a contract.

  • No single provider is best for every business. The right line depends on your address, team size and priorities.
  • Fibre broadband in Windsor can reach one side of a road and not the other, so check your exact address first.
  • FTTC suits most small offices, with up to 40Mb or 80Mb where full fibre has not arrived yet.
  • Copper lines have little upload, so one large upload can choke every video call in the office at once.
  • A 4G or 5G backup router keeps card machines and phones running if the fixed line drops.
  • Check what is free. Our packages include the business router, activation and Openreach installation.
  • In shared offices, ask whether you can have a dedicated line instead of building internet.
  • Home businesses in Old Windsor or Datchet benefit from a second line kept apart from family use.
  • Any phone or alarm still on the analogue network must move before the end of January 2027.
  • Know who raises and chases faults with the network when the line drops, and who holds the router.

Availability changes as full fibre rolls out, so we check your address before recommending any line or contract.

Frequently asked questions

Business Broadband Questions From Windsor Businesses

Is business broadband available at my address?

It depends on the exact address. Full fibre has reached many Windsor streets, while the next road may still run on copper from the street cabinet. Send us your postcode and building name, and we check each network before we recommend a line.

What is the difference between FTTC and FTTP?

FTTC runs fibre to the green street cabinet, then an Openreach engineer runs a copper line into your premises, with packages up to 40Mb or 80Mb. FTTP runs fibre all the way into your building, giving faster, more reliable speeds from 40Mb up to 1000Mb.

Is full fibre available in Windsor?

In many Windsor streets, yes, and coverage keeps growing. Full fibre can reach one road and not the next, so send us your postcode and we check FTTP at your premises before we recommend a package.

Can a home business in Eton or Datchet get a business line?

Yes. We install business broadband in home offices in Eton, Datchet, Old Windsor, Ascot or anywhere around Windsor, with business support, a free router and a line kept apart from family use.

What happens if our broadband goes down?

With a 4G or 5G backup router, your connection switches to mobile data when the fixed line drops, so card machines and phones keep working. We raise the fault and chase it until fixed.

When do we need a leased line?

When your team depends on large uploads or many cloud calls at once, or a day offline costs more than the line. We can quote both for your address.

Do you manage the router and Wi-Fi?

Yes. We supply and configure the router, set firewall rules, build separate staff and guest Wi-Fi and monitor the connection, adding access points where coverage drops.

Will cloud phones work on our broadband?

Yes. We check for full fibre and put calls first on the router, so one large upload does not choke the line. You can add VoIP for £11.99 per user with unlimited UK calls.
