Finding fastest broadband areas by postcode (i.e. which postcodes / streets have the best broadband speeds) is tricky because most of the public, free data is at regional / city or local‐authority level, or specific streets. Postcode‐level speed depends heavily on whether there’s full fibre (FTTP / FTTH), high speed cable, or whether service is still delivered via copper/fibre-to-the-cabinet etc.
Below I summarise what I found, plus case studies of specific postcodes/streets that are known to have very fast broadband, what speeds they hit, what kind of infrastructure gives them that, and caveats.
Key national / regional broadband speed metrics (2025)
These help set the context:
| Metric | What it means | Key figures / sources |
|---|---|---|
| Gigabit availability | How many premises can get full-fibre or other gigabit capable connection (1 Gbps or above) | In Ofcom’s “Area 2 / Area 3” classification (urban / rural blends), ~66% of premises in Area 2 have gigabit availability. In Area 3, ~60%. (thinkbroadband) |
| Superfast broadband (30 Mbps+) | Widely available across almost all urban regions | Over 98% of premises in England and London have superfast 30+ Mbps availability. (thinkbroadband) |
| Average / max speeds | What people could hit, in well-served streets | “Average maximum” download speed across UK rising: eg ~223 Mbps as reported in 2024 for UK average max download. Full fibre and strong cable help pull this up. (Choose) |
What makes a postcode “very fast”
From the data and case studies:
- Presence of full fibre to premises (FTTP / FTTH) or strong cable networks (Virgin Media, major alt-nets)
- New build housing estates often get FTTP from the start
- Streets where broadband providers /poles / ducts / open-access networks are modern or recently upgraded
- Less distance from local exchange / fibre node (resistance and signal degradation are less)
- Less legacy copper infrastructure
Specific fast-streets / postcodes / examples
Here are known examples of very fast broadband at street / postcode / micro-area level. If you live in one, you’re likely in one of the fastest.
| Street / Postcode / Area | Approximate speeds reported | Infrastructure / Why it’s fast | Caveats |
|---|---|---|---|
| Tynemouth Street, London | ~ 921.8 Mbps download (fixed-line broadband, from UK Fibre Connectivity Forum data) (ukfcf.org.uk) | Likely FTTP or high-capacity cable; in London many of these fast streets are served by alt-nets or modern Openreach full fibre. | May depend on specific building wiring; upload speed might be lower; “peak” speeds may drop with more users. |
| Bloxworth Close, Wallington | ~ 910.1 Mbps (ukfcf.org.uk) | Same kind of high-end residential street with full fibre or strong cable / local network infrastructure. | Availability may depend on exact house number; price premium; provider choice may be limited. |
| Lumsdale Crescent, Matlock | ~ 886 Mbps (ukfcf.org.uk) | Likely recent fibre rollout or very efficient local infrastructure. | Rural or semi-rural may have less redundancy; congestion during high usage times. |
| Ports smaller streets like Moatview Park (Belfast), Orrell Road (Wigan), etc. | 750-800+ Mbps in many cases (ukfcf.org.uk) | Strong local rollouts by cable / full fibre providers. | Similar caveats: “advertised speeds” may be ideal; real world varies. |
Regional / Local authority / Postcode-District level speed “hotspots”
Some whole postcode districts or authorities are known to be particularly strong.
| Region / District | Observed strong performance / ranking | Why strong there |
|---|---|---|
| Northern Ireland | Among the highest average max-download speeds (~259 Mbps) in some studies; high FTTP take-up. (Choose) | Good investment in fibre across both urban and rural in NI; fewer legacy copper bottlenecks. |
| Rutland (East Midlands) | Topped many county speed rankings (~362-390 Mbps) as fastest county in UK studies. (broadband.co.uk) | Sparse population helps; newer infrastructure; many full-fibre deployments. |
| London boroughs | Some areas like Bexleyheath, Hammersmith & Fulham, etc. appear in “fastest London area” tables. For example, Bexleyheath ~220-265 Mbps, etc. (broadband.co.uk) | Good fibre/cable infrastructure, high provider competition. |
| Some towns / smaller cities | Plymouth is ranked among UK’s top-10 “regions” for wifi download speed in one report (~140 Mbps average). (Invest Plymouth) | Good broadband penetration, local initiatives. |
Postcodes you could test / suspect to be among fastest
Although I couldn’t find many public maps listing postcode districts explicitly with speed ranks, based on the street-data, the following types of postcodes very likely are among the fastest:
- Postcodes in central or inner London (especially streets around SW, W, NW, etc) where hyperoptic / full fibre networks are deployed.
- Recent housing developments (new build suburbs) in places like Reading, Cambridge, Bristol, etc, where alt-nets or Openreach full fibre are aggressively deploying.
- Postcode districts served by cable providers like Virgin Media where they have upgraded their network (e.g. central Manchester, Birmingham, Leeds).
- Rural postcodes where community or local full-fibre co-ops / projects (or state-aid/ rural broadband funding) have delivered fibre infrastructure. (e.g. parts of Rutland, Scotland, Wales)
Limitations / what the data does not always tell you
- Many speed measurements are “peak” or “maximum” speeds advertised, not guaranteed or sustained speeds.
- The upload speed is often much lower than download — real-world performance for remote work / video calls depends heavily on upload.
- Even in “fast” postcode / street, the last-meter / in-building wiring (cables, walls, distance from router) often causes large speed drops.
- Take-up of full-fibre or gigabit plans may lag availability (just because you can get it doesn’t mean many do) which affects whether “fast broadband” is typical.
- The data tends to be biased toward well-served and more affluent areas, because those are first to get infrastructure and have more users submitting speed tests.

The UK’s broadband landscape has transformed dramatically over the past few years. With full-fibre rollouts, alternative network (alt-net) providers, and 5G expansions, speed differences between regions have narrowed — but postcode-level disparities remain striking. In 2025, certain areas now boast speeds exceeding 900 Mbps, while others still struggle below 10 Mbps.
This detailed report examines the fastest broadband postcodes in the UK (2025), with full case studies highlighting infrastructure, average speeds, local initiatives, and the economic or social factors driving high connectivity.
