Broadband Speed

How fast will my Broadband be?

The broadband speeds you receive can vary and will primarily depend on how far you live from your local telephone exchange - The best way to get an idea how fast your broadband could be is to visit to get a broadband speed estimate.

There's no commitment to buy anything when you use the line checker, just enter your phone number and address details and we’ll let you know what we can offer you.

Your estimated broadband speed will be displayed here when you do a line check.

This is an estimate only as the actual speed you get could still vary depending on other factors like the quality of your phone line, wiring in your house, interference from electrical devices, speed of the websites you visit and how many people are using your broadband connection at the same time – speeds can also be a bit slower in the evenings and on the weekend when more people are using the internet.

When you start using Post Office Broadband you may notice your speed fluctuating up and down in the first 10 days –this is not a fault, tests are just being run on your line to optimise the speed that you get. Please bear with it as the improved speed and stability will be worth the wait.

Tips to improve your Broadband speed

Sometimes the amount of traffic on the network can cause slowness, or an individual website may be 'slow', but if you're suffering from a consistently poor connection speed on all the websites you visit, here are some things to try:

  • Check that all wires to your wireless router are firmly connected
  • Avoid heavy traffic - The speed of your Internet connection depends on a number of factors - one important factor is how many other people are using the network in your house, and another important factor is whether it is a 'peak period' or not. The peak period is around 5pm to 12 midnight.So, for example, if someone uses peer-to-peer software in your household, they can schedule their internet use at times when other people aren't using the internet.
  • Is your computer powerful enough? - Generally, the more powerful computer that you have then the faster your browsing experience will be. For us to provide the Broadband Service, you must have a fully working and licensed personal computer that meet a set of requirements.
  • Keep your Router away from sources of electrical interference - Common household electrical items can affect your broadband speed so make sure that your Router is placed at least five feet away from things like Dimmer switches, Stereo or PC Speakers, Christmas Tree lights, Halogen desk lamps, Televisions and monitors, 900MHz cordless telephones and AC Mains cords.
  • Clear your browser's cache - Slow web pages can also be caused by a full cache of web pages or incorrect settings in your web browser. Regularly clearing the cache and restoring your default settings may help to improve speeds.
  • Pause any background downloads - If you are downloading video, music, or other files, then your connection will slow down - and consequently, browsing the web may be a slower experience. To improve your broadband connection speed pause the download, and resume it at a later time.
  • Check for Spyware / Adware - Are there any programs running in the background which may be affecting your connection speed? Viruses, spyware and some adware are together known as malware (short for "malicious software"). These programs can get on to your computer without your knowledge and run in the background while using up resources. Find out more about spyware/adware and how to remove it.
  • Check your firewall - Have you raised the "security level" or equivalent setting on your firewall software? If you have it set to a very high security level this may give the appearance of a slower connection. This is because when the security level is high your firewall software will be closely examining everything being downloaded to your computer, which takes time. This is a matter of personal choice, but you may wish to consider lowering the security level to the default or normal setting in order to speed things up. Also, check that you are only running one firewall and one antivirus program. Running more than one of each can cause processor overload and incorrect message reporting on intruder detection, hacker attacks, and more commonly virus reporting.
  • Use the main telephone socket - Try to connect your Router directly to your home's main telephone socket, with a micro-filter connected in-between the two. Don't use an extension telephone socket if it can be avoided - this will reduce the chances of receiving electrical interference. You can consider connecting your computer wirelessly to your Router, instead.

Information on Traffic Management

A small number of customers use peer-to-peer file sharing services to upload and download files, such as music and videos, containing very large amounts of data. Please be aware that uploading and downloading copyright files such as music and films without the consent of the copyright owner is unlawful. Those copyright owners are able to seek court orders for us to disclose your details to them.

Uploading and downloading files uses a lot of network capacity and we will monitor usage by looking at a number of factors including the amount of time excessive usage continues as well as the bandwidth used. The systems that are used to provide Post Office® Broadband can identify very high bandwidth users and those using peer-to-peer file sharing services.

We may restrict your usage of peer-to-peer file sharing services at peak times, to ensure fairness to all users.

Peak times are 4pm-Midnight, Monday-Sunday (including Christmas and Bank Holidays), UK time.
