SO19 broadband FAQs
Is 97.8% gigabit realistic?
Yes. SO19 has had aggressive rollout of cable and fibre, so gigabit is the norm rather than the exception.
What about the 2.2% without gigabit?
These postcodes sit on superfast instead. Superfast still handles most household demands comfortably.
Why is SO19 better than SO18?
SO19 has 97.8% gigabit versus SO18's 96.5%. Both are exceptional; SO19 simply edges ahead.
Will my SO19 postcode need a broadband check before moving?
Not essential. Most postcodes have gigabit. If you run heavy operations from home, verify, but for typical use, expect gigabit.
