DL5 broadband FAQs
Why is superfast so high but full fibre relatively low in DL5?
Copper broadband networks were deployed decades ago and now serve 97.3% of postcodes. Fibre rollout is newer and less complete at 61.9%, representing ongoing modern network investment.
If I have superfast copper, can I upgrade to fibre?
Fibre is available to 61.9% of postcodes. If yours is not in this footprint yet, check with your provider and council for rollout timelines or commercial availability.
What speeds should I expect on copper superfast?
Copper delivers 30-300 Mbps, typically 50-100 Mbps for most postcodes. Adequate for standard household use and light remote work, but constrained for large file transfers or multiple simultaneous streams.
Is DL5 a poor choice for remote workers?
Not necessarily. If your postcode is in the 61.9% with gigabit access, you have excellent speeds. If on copper superfast (33.1%), most remote work is feasible, though video-heavy or latency-sensitive work benefits from fibre.
