Where fibre is available at comparable pricing, take fibre. Where it is not, strong 5G is the closest alternative there has ever been — and for many households the difference is no longer noticeable.
Direct comparison
| Fibre | 5G | |
|---|---|---|
| Consistency | Dedicated line — unaffected by neighbours | Shares tower capacity |
| Latency | Lowest | Low, but higher than fibre |
| Setup | Installation and lead time | Same day, plug in a router |
| Availability | Only where built | Metro-focused, expanding |
| Moving house | New installation needed | Often location-locked anyway |
Where 5G genuinely wins
- Speed of setup — working the same day rather than after a lead time.
- Short leases, where installing fibre at someone else’s property makes little sense.
- Areas fibre has not reached, which is most of the country.
Where fibre still wins
Peak-time consistency. A dedicated line is unaffected when the neighbourhood comes online in the evening; a shared tower is. For households doing video calls or gaming during busy periods, that gap is the one that shows.
Test 5G before committing
5G uses higher frequencies that travel shorter distances and penetrate walls less well, so coverage varies by property and even by room. Test at the router’s intended position, in the evening.
If the signal is marginal, solid LTE often performs better than weak 5G. See 5G vs LTE internet and check coverage before an internet deal.

Frequently asked questions
Is 5G as good as fibre?
In strong coverage, close for most household use. Fibre remains more consistent at peak times.
Which installs faster?
5G — usually same day, with no installation.
What if my 5G signal is weak?
Solid LTE often outperforms marginal 5G. Test first.
Can I move a 5G package?
Many are location-locked to the registered address. Confirm before moving.
