Top 10 UK Fastest and Slowest Streets for Broadband Speed 2020

A new report has used data from 398,973 consumer speedtests to identify the top 10 fastest and slowest UK streets for broadband ISP download speed, which finds that Queens Road in Weybridge (Surrey) was the “slowest” on 0.12Mbps and Dale Lane in Appleton (Cheshire) is the fastest at 639.67Mbps. But there are caveats.

The uSwitch.com research is based on speed tests conducted over a 12-month period from 1st October 2019 to 30th September 2020. In order for a street to qualify for inclusion, tests from at least 3 unique IP addresses and at least 10 residential properties were required at a postcode.

NOTE: The study found that average download speeds across the UK were 71.8Mbps (Megabits per second).

The good news is that the number of broadband users enjoying faster speeds is growing. Some 54% now get “superfast” speeds of more than 30Mbps (up from 22% five years ago). But at the same time it’s worth remembering that superfast networks currently cover around 96% of UK premises, which means that a lot of people have yet to upgrade.

Caveats and Context

As usual one of the biggest problems with studies like this is that they can easily be taken at face value, which is a problem because consumer speedtests don’t correctly reflect the actual underlying availability of faster networks. However, uSwitch does point out that, of the ten slowest streets, seven (70%) have access to a quicker service.

Clearly awareness of faster packages is still a key problem for some people. In other cases, consumers may be aware that a faster service exists, but they have simply chosen not to upgrade due to various issues, such as the potentially higher price, being stuck in a long 18-24 month contract term or a simple lack of need / desire for anything faster.

Speedtests can of course also be influenced by other factors too, such as poor home wiring, user choice of package (e.g. 1Gbps could be available but most people may still pick a slower and cheaper tier on the same fibre), local (home) network congestion and slow WiFi performance etc. In short, take these results with a good pinch of salt.

The Top 10 Slowest UK Streets for Broadband

Rank Street Name and Location Average download speed (Mbps) Superfast broadband available? Ultrafast broadband available?
1 Queens Road, Weybridge, Surrey 0.12 Yes Some
2 Hatchett Road, Feltham, Hounslow, London 0.38 No Yes
3 Monkton, Honiton, Exeter, Devon 0.45 No No
4 Church Street, Great Maplestead, Halstead, Essex 0.47 No No
5 Limmer Close, Wokingham, Berkshire 0.48 Yes No
6 Waterley Bottom, North Nibley, Dursley, Gloucestershire 0.49 Some No
7 Spencer Road, Caterham, Surrey 0.55 No Some
8 Ringhaddy Road, Killinchy, Newtownards, Northern Ireland 0.62 No Some
9 Fishtoft Drove, Frithville, Boston, Lincolnshire 0.66 No No
10 Sopwith Crescent, Wimborne, Dorset 0.67 Some Yes

One curious oddity in the way uSwitch has done this is that they’ve put ‘Yes’ or ‘Some’ under “ultrafast broadband” availability for several streets, yet at the same time left “superfast broadband” as ‘No’ on those same streets, which doesn’t make much sense to us (ultrafast connections are faster than superfast and thus if ultrafast is a ‘Yes’ then it follows that superfast is also ‘Yes’).

The Top 10 Fastest UK Streets for Broadband

Rank Street Name and Location Average download speed (Mbps)
1 Dale Lane, Appleton, Warrington, Cheshire 639.67
2 Longhedge, Caldecotte, Milton Keynes, Buckinghamshire 568.18
3 Old Ballynahinch Road, Lisburn, Northern Ireland 563.85
4 Montvale Gardens, Leicester, Leicestershire 452.02
5 Mill Close, Henlow, Bedfordshire 360.59
6 York Road, Guildford, Surrey 352.67
7 Chapel Road, Oldbury-on-Severn, Gloucestershire 284.92
8 Woodcroft Road, Liverpool, Merseyside 282.21
9 Cairn Wynd, Inverurie, Scotland 276.40
10 Sandy Hamilton Place, Inverurie, Scotland 253.17

We should add that business class high-capacity leased lines might be impacting some of the above the results and it’s similarly unclear whether mobile connections were included or not. Lest we forget that the slowest streets will be those precious few isolated locations that still struggle to get a working internet connection at all or have too few results, which won’t show up above.

    Church Street, Great Maplestead, Halstead, CO9 2RH

    1Mb – 3Mb
    Your download speed range

    Your Stay Fast Guarantee 1Mb

    Upload speed range 1Mb – 1Mb

    So the study shows predominantly wealthy leafy suburbs have the fastest broadband. Who’d have thought!

    This is backed up by “The study found that average download speeds across the UK were 71.8Mbps” when as stated only just over half of all customers can get “superfast” speeds of more than 30Mbps

    (Though the outdated superfast definition translates to “about adequate” in 2020 not at all the “superfast” it still pretends (and OFCOM allows) it to be.)

    So 46% of the UK still has to “make do” with less than 30Mbps, basically.

    As you say – somewhat flawed as it is based only on users running a U Switch speed test on their existing connection. So the results are what that person has, not what they can get.

    Queens Rd in Weybridge…. which they show as the slowest in the U.K. at 0.12Mbps has Virgin Media M500 availability at 500Mbps according to the VM postcode checker and ThinkBroadband.

    1. Andrew Ferguson says:

      Queens Road Weybridge is 3.5 km long with plenty of VDSL2, from a number of cabinets and plenty of 500 Mbps cable options.

      Of course uswitch say they do include the availability column, but look at coverage outside ISPreview and its just slowest this, fastest that. There might be a couple of words on faster is available.

      Perhaps I should start issuing random lists of ten sub 2 Meg postcodes once a week and 10 where FTTP is available.

    2. Andrew Ferguson says:


      Centered on the road and shows that thinkbroadband gets from tests on ispreview, itself and other sites.
