Frequently asked questions

How do I check broadband availability at my postcode?
Enter your full UK postcode in the broadband postcode checker. You'll see fixed-broadband availability, full-fibre and gigabit coverage, and mobile signal for all four networks at that address, sourced from official Ofcom data.
Where does this broadband coverage data come from?
Availability figures come from Ofcom's Connected Nations programme, the UK regulator's official open dataset of fixed-broadband coverage, combined with ONS/OS postcode location data. Mobile coverage uses Ofcom's mobile availability data.
Can my business get full-fibre or a leased line?
In most areas, yes. Where full fibre (FTTP) and gigabit are live, we quote ultrafast symmetric connections; where they aren't, a leased line still delivers guaranteed speed with an SLA. Check your postcode, then request a quote.
