Internet Speed Test Ofcom

Are you getting the broadband speed that you paid for?

You've got things to do. Even if you only use your internet connection for a few things, it still needs to work properly.

Ofcom-accredited price comparison sites and have speed checkers. Try to use different devices to see if you experience the same problem with each. If the problem seems to be affecting one device more than others, check you have the latest security software installed. Or, if you want to test your existing broadband speed, use the Ofcom broadband speed checker. If you’ve recently switched broadband providers, it can take a few days for your connection speed to stabilise.

If your broadband connection or WiFi signal is intermittent or slow, it can be really frustrating. If you're using it for work, poor broadband can be disastrous.

Compare 500+ broadband deals from UK service providers. Broadband news, reviews and speed test from the longest running and trusted independent broadband information website (formerly Countdown to the new broadband safety net. Everyone in the UK will have the right to request a decent and affordable broadband connection from March next year due to Ofcom implementing the governments ‘universal broadband service’. This will give eligible homes and businesses the right to request a decent broadband connection. Broadband Speed Test. Put your connection to the test and find out how fast it really performs. We all know that broadband suppliers advertise their speeds as 'up to' a certain level. Ofcom have also published average broadband speeds recorded across the UK, including individual figures for the largest providers, different types of.

When you signed up to your broadband provider, they should have committed to a certain minimum speed. If so, use that as your benchmark.

What do my speed test results mean?

Good question! After you hit the 'Go' button below, you'll see the following results:


The speed that things come to you when you're trying to receive them from the internet. This can be pictures, videos, or web pages. In theory, the higher this number is, the faster you should receive what you're looking for online.

How quickly you can speak to the online world. When you're sharing a photo/video or just trying to communicate, your upload speed is vital.



Information is sent from your computer across the internet in “packets” - bundles of information to be read by the computer that receives it.

Usually, 'packets' are sent at regular intervals and take a set amount of time to reach their destination.

The time that a packet takes to get to its destination is referred to as 'latency' or 'ping'.

Whenever you experience delayed responses online - this could be due to a higher than desired ping.

Lower is better when it comes to ping. A result below 50 ms should be expected from any decent broadband connection.


Getting a bit more complicated here, but basically, it means fluctuation in the responsiveness of your connection (measured by 'ping'). Jitter is the fluctuation of your 'ping' result over time.

Again, lower is better for jitter results.

If ping and jitter seem confusing, you're not alone! Just remember that lower is better.

You should see less than 50ms ping and less than 5ms jitter on a good day.

Here's how UK broadband speeds have improved over time:

If your speeds are nowhere near those shown in the chart, then you're being left behind!

It may be time to change to a provider that will give you a minimum guaranteed broadband speed.

The Office of the Communications Authority ('OFCA') has commissioned SamKnows Limited ('Contractor') to design, establish, operate, support and maintain a system located at a local data centre for provision of broadband performance test service in Hong Kong (the 'System').

The System is designed to handle broadband performance tests within the territory of Hong Kong and enables broadband service users to measure the performance of their broadband connections on the following aspects –

Download speed

The rate at which data is transferred from the test server to the user device.

Upload speed

Internet Speed Test Ofcom

The rate at which data is transferred from the user device to the test server.

Network latency

The total time it takes to transfer a data packet from the user device to the test server and then to transfer back to the user device.

Packet loss

The percentage of data packets lost with respect to the data packets transferred from the user device to the test server.


The variation in the delay of data packets received.

Users may carry out broadband performance tests via OFCA's website ('test website') at, or through mobile software applications ('mobile apps') installed on devices operating with iOS or Android mobile operating systems. The mobile apps can be downloaded for free through the following channels -

iOS version:iTunes App Store

While the test website and mobile apps are available free of charge, users should be mindful of additional service charges which may be incurred from the data usage involved in performing broadband performance test. In particular, if users are located outside Hong Kong, they may need to bear additional service charges for the data usage and the charges payable may be substantial.

Mobile Data Usage Involved in Performing Test

The data usage involved in performing broadband performance test through mobile apps varies with the speed of mobile broadband connection under test and the time required for completing a test. For instance, it may vary from several megabytes ('MBytes') for a 128 kilobits per second ('kbps') mobile broadband connection to several hundreds of MBytes for an ultra high speed (300 megabits per second ('Mbps') or above) connection or even more than one thousand MBytes for a 1000 Mbps or above connection. Users are advised to keep track of their data usage from time to time in order to avoid any unnecessary mobile service charges.

Factors Affecting the Test Results

The speed measured by the System may be lower than those claimed and provided by broadband service providers ('BSPs') in their service plans ('claimed speed') due to various factors which may include, but not limited to -

  • End-to-End Speed – The claimed speed commonly refers to the maximum permissible speed supported by the connection between the BSPs and their customers, which may be only part of the end-to-end route under test and may not be representative of the end-to-end speed;

  • Overhead – When data are being delivered to and from the users over the broadband connection, there is overhead being introduced by the transmission and service platforms of the BSPs on top of the actual data being delivered and this may cause some degradation in the performance;

  • Network Conditions – The Internet is shared by numerous users and applications. Performance of a particular broadband connection is inevitably affected by the traffic being generated by these other users and applications;

  • Associated Services – The associated services provided by the BSPs may take up certain capacity of the broadband connection. For instance, if there are other services (e.g. Internet Protocol ('IP') television service) sharing the same broadband connection at the same time, the performance of the broadband connection may be adversely affected;

  • Number of Concurrent Users/Applications – The performance will be affected by the number of concurrent users or applications (e.g. Over-the-Top or 'OTT' application) sharing the same broadband connection;

  • Relative Position between the User Device and the Service Platform – The physical distance between the user device and BSPs’ equipment, especially in the case of mobile services, may affect the performance. In general, the closer the user device is to the mobile base station of a BSP, the better will be the performance of the mobile broadband connection;

  • Software Running on User Device – Some software such as firewalls or anti-virus applications may affect the performance of the broadband connection. User may need to temporarily disable or even uninstall the software in question before performing the test; and

  • Configurations of User Device – For high speed broadband connections with speed up to 1000 Mbps or above, the measured speeds may be limited by the user device under test. In order to conduct the test with accurate result, the minimum recommended requirements are Core i7 CPU at 3 GHz, 6 gigabytes random access memory, 1000-BaseT Ethernet port, operating with Microsoft Windows 7 and using Internet Explorer 11, or an equivalent setup.

To ensure that the System can accurately measure the speed of fixed broadband connection provided by a BSP, the computer running the test is recommended to be connected to the customer termination point of the BSP at the customer premises through a direct cable connection to avoid any bottleneck which may be introduced by other network equipment. Depending on the minimum requirement for the transfer of test file, a minimum speed of 512 kbps for fixed broadband connection may apply.

Data Speed Required for User Applications

Internet Speed Test Ofcom Free

Data speed generally refers to how fast data are transmitted to/from user equipment or device. It is usually measured in units of Mbps or kbps. 1 Mbps equals 1000 kbps. Downloading a song of 4 MBytes requires less than 40 seconds at a data speed of 1 Mbps while downloading the same song will require a longer duration of about five minutes at a data speed of 128 kbps.
