LU3 broadband FAQs
Why does LU3 have near-universal superfast but no full fibre?
Cable networks provide gigabit and superfast coverage. Full fibre, typically deployed later or in parallel, has not reached LU3. Cable alone supplies the modern broadband.
Is LU3 the best-connected Bedfordshire postcode in this batch?
LU3 and LU4 both reach 95.2% gigabit, outpacing other Central Bedfordshire codes. They represent the Bedfordshire leaders.
What's the practical meaning of 0.1% below superfast in LU3?
Negligible in absolute terms; it affects fewer than one postcode in 818. This is rounding-level variation.
Should I prioritise LU3 over LU1 or LU2 for cable gigabit?
LU3 and LU4 offer higher gigabit reach and better superfast coverage. LU2 has the most below-superfast postcodes. If cable gigabit is your priority, LU3 is a better bet.
