Our verdict on each
Astound
Astound suits US households that want matching download and upload speeds, a low entry price and no contract to be tied into, and the same account can carry mobile lines. Entry pricing starts at $19.95 a month, Gig tiers arrive with Whole Home WiFi included, and the setup fee is $0.
Zzoomm
Zzoomm suits households already inside its full-fibre build that want a quick upgrade and can live with the jump at renewal. Entry pricing starts at £20 a month, while post-term pricing runs £32 to £70, so the second bill is the figure to weigh before signing.

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.
Zzoomm
Pros
- Entry pricing of £20 a month with £0 setup keeps the first bill small.
- Free WiFi 6 or WiFi 7 router included is part of the package rather than a separate purchase.
- Upload matches download at 2,300 Mbps, so heavy uploads are not the bottleneck.
Cons
- Renewal pricing is the weak point, with post-term monthly cost at £32 to £70 against a £20 entry price.
- Coverage rests on a build of 600,000 premises, so any address outside that footprint cannot order.
- The line is fttp alone, whereas Astound lists cable and fttp, so homes that want cable have fewer options here.
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.
Zzoomm
Who it suits
- Households inside Zzoomm's full-fibre build that want 2,300 Mbps in both directions.
- People who would rather not buy hardware, since Free WiFi 6 or WiFi 7 router included comes as standard.
- Anyone who needs a static IP, plus help by email, chat and phone.
Who should look elsewhere
- Anyone who wants cable alongside full fibre should look at Astound, which lists cable and fttp.
- Readers chasing the highest headline download should look at Abissnet, which reaches 10,000 Mbps.
- Houses outside GB can rule Zzoomm out; EarthLink lists fttp, 5G and satellite as a different mix.

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.
Zzoomm
What does Zzoomm broadband cost at the start?+
The entry plan starts at £20 a month, with faster full-fibre plans listed above it on the same network and the same term length. Setup costs £0, so there is no activation charge to add to the first bill.
Which contract lengths can I choose?+
Terms come in 1, 12 and 24 month lengths, so a shorter commitment is available for anyone who does not want a long tie. The trade-off is the exit terms, since leaving before the minimum period is over brings a charge for early exit.
