Another huge UK broadband speed upgrade confirmed but is your postcode on this list?

If your downloads are still slower than a snail trudging through treacle on a Sunday morning then good news could be coming soon. BT's Openreach, which supplies broadband infrastructure across the country, has just confirmed the next batch of areas that will see ageing copper technology phased out in favour of fast full fibre.

For those not in the know, old copper cables are only capable of delivering downloads at a speed of around 70Mbps. Full Fibre to the Premises (FTTP) however, can whizz files and films into living rooms at a rate that can exceed 900Mbps - that's over 10 times faster.

It basically means a full a full HD movie can beamed to your telly in around 40 seconds rather than waiting for almost 10 minutes.

To help speed up the process and get more people switched over to this faster technology, Openreach says it has now warned firms - such as BT, Vodafone and Sky - that they will no longer be able to sell legacy plans to customers in 28 new locations. This will come into effect once a 12-month noticed period has taken place.

So, from later next year, homes taking out a new deal or moving suppliers will instantly get access to FTTP.

"As Openreach rolls out our ultrafast full fibre network across the country - it makes no sense to keep lots of different old technologies running – it’ll be very expensive, replacement parts are no longer being made, and it won’t allow the business to push forward with plans to give the UK world class connectivity as quickly as it would like," Openreach confirmed.

You can check your postcode here to see if FTTP is in your street and if you can get quicker speeds.

Here's the full of locations that will be switched to Full Fibre only next year.

Four Oaks • Dysart • Newcastle West • Biggleswade • Caldy • Allerton • Eltham • West Drayton • Sutton • Prestonpans - Port Seton • Upper Largo • Berwick • Knutsford • Malton • Stamford • Cleish Hills • Drumclog • Landrake • Bickleigh • Bolney • Crosswell • Abbotts Ann • Stichill • Burravoe • Tonbridge • Tenterden • Dartmouth • Staines

Of course, when you make the switch to FTTP you'll be offered the chance to take advantage of much quicker downloads just make sure you pick the right speed for your needs.

For example, a person living on their own, watching the odd boxset online and sending a few emails doesn't need anything faster than around 70Mbps.

However, a busy home full of people streaming, working and playing games online will need a much better connection.

Think of your broadband a bit like a motorway, the more traffic running along it, the slower it gets.
