Pros and cons
Astound
Pros
- Download of 5,000 Mbps matches upload of 5,000 Mbps, so sending a large file is as quick as downloading one.
- The setup fee is $0, and it ranks 1 of 86 on that measure, ahead of every other brand compared.
- Service runs on cable and fttp, so one provider can cover a cable street or a fibre to the home street.
Cons
- EU roaming is paid, so European travel is billed separately.
- Data rollover is no, so unused mobile allowance does not carry into the next cycle.
- A credit check is required on the mobile side, which adds a step before a line is active.
Lightning Fibre
Pros
- Max download of 10,000 Mbps and upload of 900 Mbps put it at rank 28 on upload, ahead of most full fibre rivals.
- No price rise during the contract term, so the £24 entry price holds for the whole term.
- Setup fees run £0 to £150, and rank 1 on setup fee puts it at the top of the field.
Cons
- Renewal pricing after the contract climbs to £34 to £49, ranking 14 on post contract price.
- Plan terms run 1, 12 and 24, so the longer options tie you in for a long stretch.
- Support runs on email, phone and help centre only, with no live chat listed.
Who each suits
Astound
Who it suits
- Households in US whose street already has cable or fibre to the home and who want equal download and upload speeds.
- Families adding mobile lines to the same account, where a multi line discount and rolling billing apply.
- Renters and short-stay households, since No cancellation penalty; change or cancel anytime.
Who should look elsewhere
- Buyers who want a fibre to the home provider and nothing else, because cable and fttp includes cable while Abissnet and Kinetic list fibre to the home alone.
- Homes a wired network does not reach, where EarthLink adds fttp, 5G and satellite options.
- Travellers who expect European roaming to come included, since EU roaming is paid.
Lightning Fibre
Who it suits
- Households already inside Lightning Fibre's build area who want symmetrical fibre speeds
- Anyone sending large uploads for work, streaming or backups, given the 900 Mbps figure
- Buyers who want the price held flat through the term and a router in the box
Who should look elsewhere
- Buyers who want short terms, since plan terms run 1, 12 and 24
- Anyone outside GB, where the service does not reach
- Households priced purely on renewal cost, where post contract pricing sits at £34 to £49

Questions about each
Astound
How much does Astound broadband cost a month?+
Plans start at $19.95 a month on the entry tier. The listed lineup then steps up through Gig and multi-Gig WiFi plans, and every plan shown is on no-contract terms, so the monthly figure is the whole commitment. Whole Home WiFi is included with Gig plans rather than sold as an extra.
Is there a setup or installation fee with Astound broadband?+
Setup costs $0 to add, and in this comparison the brand ranks 1 of 86 for setup fee, ahead of every other brand measured on that point. Equipment also counts: Whole Home WiFi is supplied with Gig plans, with the top tier hardware paired to the quickest speeds.
Lightning Fibre
What does Lightning Fibre cost to start?+
Entry pricing starts at £24, and that is the introductory rate for a fixed term rather than a permanent price. Setup fees run £0 to £150 depending on the line. After the term, prices move to £34 to £49, so budget for that step when comparing against cheaper rivals.
How fast is Lightning Fibre?+
Max download reaches 10,000 Mbps and upload runs at 900 Mbps, which is close to symmetric and good for large uploads. That download figure places Lightning Fibre at rank 1 of 114 brands, and upload ranks 28.
