DL17 broadband FAQs
Is 73% fibre coverage good for County Durham?
Yes. This matches the UK average of 69% full fibre premises passed and places DL17 in the upper half of postcode district rankings.
What speeds should I expect if I live in the 18% of postcodes without gigabit?
Those postcodes typically receive superfast 30-300 Mbps from copper or hybrid networks. This speed range is adequate for household use and light to moderate remote work.
Will my postcode definitely have fibre at the street cabinet?
Fibre reaches 73% of postcodes. If yours is not in this footprint, it likely has copper superfast or is scheduled for fibre rollout. Check with your provider and council.
Should I wait for fibre if my postcode currently has copper?
If you need gigabit speeds now, copper won't deliver them. Fibre timelines are uncertain and provider-dependent. If 30-300 Mbps suits your current needs, the wait may not be worthwhile.
