How 0845 Numbers Work

0845 telephone numbers are 'virtual' meaning they sit on an existing landline or mobile, which is why they deliver the great benefits listed above. For many customers with inclusive minutes with BT, calls to 0845 numbers are completely free!

With fixed line BT 01 and 02 numbers you rarely get the chance to choose your own number. With Windsor Telecom, you can choose from thousands of highly memorable 0845 numbers, helping customers to easily remember you and standout from the competition. One of our customers, a recruitment consultants with offices in London and Hertfordshire, uses our highly memorable 0845 460 0 460 number to create standout in an extremely competitive market. Thousands of organisations across the UK use 0845 numbers, including Jobcentre Plus, countless local county councils, charities such as the Alzheimer's Society and The Samaritans, as well as numerous travel brands like Butlins.

When a customer dials your virtual 0845 telephone number, the call is instantly routed to your existing landline or mobile number (referred to as your 'target'). Conveniently, you can change this target number at any time online using My Windsor, or via the phone with our Instant Call Rerouting service. 0845 numbers can be set up quickly and you don't need to install and maintain any software or hardware.

Diverting To Mobile

Add 250 minutes of talk time to your mobile routing facility for £10 per month. This works out at just 4p per minute instead of the Pay as you go rate of 9.95p. Another benefit of this popular package is that any extra minutes used over the 250 limit are charged at just 6p per minute. You can purchase Divert To Mobile 250 as a customer via My Windsor, our online portal. View Mobile Divert Costs.

Fax To Email

You can also choose to use a 0845 telephone numbers as a Fax to Email line, where faxes are received via your email. This is a great alternative to having a fax machine, which is traditionally expensive what with the on-going maintenance and material costs. What's more, you don't need a physical landline if you choose Fax to Email, again saving you a lot money.

  • "We have used Windsor Telecom services since 2006 and
    their products enable us to run our business professionally and very cost effectively. The systems are very easy to manage
    and we definitely wouldn’t be without them. Added to this the account management support is superb – very efficient and friendly. I wouldn’t hesitate to recommend Windsor Telecom
    to any business."


    Debbie Wren, Partner, Dovetail

    "I decided to use Windsor Telecom having become
    disgruntled with my old supplier of 0845 numbers.
    not only are their prices competitive, but the service they provide is outstanding. They are always there to help and the team are a pleasure to deal with. The reporting side of Windsor is easy to use and very thorough. I would not hesitate in recommending Windsor Telecom to colleagues."


    Fergus, JJ Marketing

  • "Thanks to Windsor Telecoms revolutionary online call management system we don’t have to ever miss a single sales call. Our clients are guaranteed to speak to an agent every time without ever hearing an engaged tone. While the feature to divert anytime anywhere frees up our team to multi task on the go saving thousands on the cost of a desk bound telephone receptionist employee."

    Roni - sohoprint.co.uk

    "The convenience and speed that I can switch
    my 0845 number to wherever I am is is truly invaluable to my business and it was the best thing that I have ever purchased in fact without it my business would not have grown as it has in the past 5 years from a garden shed at the bottom of my garden to two modern factories we have today."


    Rick Gathercole, Managing Director - Lillypad Leisure

  • "I have been using Windsor Telecom for the last three years now and all I can say is I am completely satisfied not only the reliability of the system and billing process (easy to use and understand) but with the helpful and "can do" attitude of the staff. Windsor Telecom provide me with an exemplary service."

    Barry Paschali, Paschalli Greener Working Solutions

    "We've been using Windsor Telecom for a series
    of 0845 numbers for several years. Never a problem, always a great service and system, which is why we've recommended them to many friends and clients."


    Rory - embado.com

  • "As a start up business it was important for us to secure an easy to remember telephone number, have the ability to migrate it to another number, and to have continuity of service. Windsor telecom offered all this at a very competitive price. I have little to no need to contact them - which is a positive thing - as I have plenty to concentrate on as I grow the business! The on-line invoicing is clear and concise and is eco-friendly too being paperless which fits with our aims around sustainability too."

    Yvonne Finlayson - fillnfixit.co.uk

    "Windsor Telecom have provided my company
    with a very easy to operate service, coupled with outstanding customer service. Our account manager responds to any queries almost immediately, with easy to follow instructions and constructive advice. I would recommend Windsor Telecom to others, with the only downside being that I wish I'd found them sooner!"


    Debi - bizikids.co.uk

  • "Just wanted to say thanks for your help getting Instant call rerouting Plus added to our services so quickly. As usual your response was fantastic... I don't imagine that we are one of your bigger customers but we certainly feel like one of your important ones! Please pass on my thanks and best wishes to your team. Go Windsor!"

    John Palmer, Director, FloorPlan Online

    "From my initial call to Windsor Telecom they
    were helpful, knowledgeable and listened to what I actually needed before discussing solutions. One of the key points for us is the fact they have Account Managers meaning that you can actually talk to someone and receive a personal service – so many of the other providers will only communicate with you by email. 10 out of 10 for customer service!"
