Broadband speeds in Buckinghamshire

Share of premises by the fastest download speed available, averaged across every Buckinghamshire postcode.

Measured performance and recorded infrastructure point in different directions here. Ookla test data puts the average download at 210.4 Mbps, yet the dataset shows full fibre at only 0.5% of postcodes, with gigabit-capable coverage of 72.6% mostly registering as cable network reach instead.

Superfast availability sits at 93.7%, a few points under the national 97%, and 2% of postcodes record speeds below 10 Mbps. Fibre itself is patchy in the data. MK19 tops the table, with fibre at just over four in ten of its postcodes, and RG9 manages roughly one in five, while HP10, HP11 and HP12 all show zero. Across 15,629 postcodes and 48 outward codes, the swing between a fast measured average and a thin fibre footprint is the defining feature. Read the 210.4 Mbps figure as evidence that quick connections are common, and treat any single address as unconfirmed until checked.

Buckinghamshire at a glance

Buckinghamshire households sit in an odd spot. Real-world speeds measured by users are high, but anyone whose heart is set on a full fibre product will find the recorded coverage thin at 0.5% of postcodes. The 2% slow tail looks small in percentage terms and still amounts to over 300 postcodes across an area this large, so movers should verify the specific address before committing.

Buckinghamshire broadband FAQs

How fast is broadband in Buckinghamshire in practice?

Speed tests average 210.4 Mbps for downloads, close to three times the typical urban UK figure of about 75 Mbps.

Why is the full fibre figure so low if speeds are high?

The dataset records full fibre at just 0.5% of postcodes, while gigabit-capable coverage of 72.6% counts other technologies such as cable networks. High test speeds can come from those services.

Which outward codes have any full fibre?

MK19 leads, with a little over four in ten of its postcodes covered, followed by RG9 at about one in five. Several others, including HP10, HP11 and HP12, show none.

Is any of Buckinghamshire still on very slow broadband?

Yes, 2% of the 15,629 postcodes record sub-10 Mbps speeds, roughly 300 postcodes.

Does superfast coverage match the rest of the UK?

It runs a little behind, at 93.7% of postcodes against roughly 97% nationally.
