*Broadband speeds - things you need to know

Unlimited Broadband offers speeds of up to 17Mb/sec*, ideal for:

  • Price fixed over an 18-month contract**
  • Everyday tasks like online shopping and banking
  • Watching standard-resolution videos


Broadband speed can vary significantly depending upon your location, phone line, home wiring, time of day, electrical interference and how many people use your network at once. Because of these factors, your speed may be lower than the advertised up to 17Mb/sec for standard broadband, or up to 38Mb/sec or 76Mb/sec for Fibre Broadband or any speed estimate we provide. We'll estimate your download speed when you check availability at your address, but your actual speed could still be slower. For more information see http://www.postoffice.co.uk/broadband-phone/broadband/broadband-speed 

Up to 3x and 7x faster: Post Office Unlimited Fibre Broadband (up to 38Mb/sec) and Post Office Unlimited Fibre Broadband Plus (up to 76Mb/sec) is up to 3x and 7x faster compared with the UK’s average standard (ADSL 2+) broadband speed (9.9Mbit/s) Ofcom UK Home Broadband Performance report November 2016 (published April 2017) available at https://www.ofcom.org.uk/research-and-data/telecoms-research/broadband-research/uk-home-broadband-performance-201
