A fibre broadband service, with an optional landline service for residential customers.

This offer is only available when bundled with an electricity service.

When your house is connected to our network via a fibre optic connection, the throughput is both higher, and of a better consistency, than ADSL broadband. This means that fibre will deliver a faster speed.

Prices are current as at 10 July 2025. All pricing is subject to change with 30 days’ notice.

To find out more about our current pricing give us a call on 0800 789 505.

There is no upfront installation charge for standard fibre aside from router postage and handling. However, if your home is more than 200m from where the fibre cable access point is on the street, or you need additional in-house wiring installed, there may be an additional installation cost.

If you cancel your fibre services after the local fibre company has commenced the installation process, but before your services are live, charges may apply.

Find out more about the installation process.

As set out in “Set up charges” above, additional charges may apply for items such as nonstandard installations and additional in-home technician work performed at the time of connection.

Electricity and gas (if applicable) charges will also apply for your energy services.      

Actual speeds you experience are affected by many factors including the device you are using and its capabilities, the number of devices connected, your operating system and web-browser, and if you’re connecting wirelessly to your router.

Find out more about factors that may influence your speed.

If you have a router supplied by Mercury, this router is capable of providing the industry national peak time average speeds, subject to the other factors described above. If you are using a router not supplied by Mercury, you may not be capable of receiving the stated speeds for Mercury’s fibre service.

Mercury customers on broadband plans are currently not shaped in any way.

From a connectivity point of view, unlimited data plans are treated in exactly the same way as limited or capped plans.

Generally, our peak traffic times are between 3:30pm and 11:00pm. Customers may experience congestion during these periods.

At peak times there may be congestion on the network however, we are always working to provide the best possible service we can.

We do, however, reserve the right to apply traffic management policies to customers on unlimited data plans should this become required in the future.

We have a service restriction policy in place which may influence your broadband performance.

See clause 5.5 of the phone and internet terms.

Your broadband service requires mains electricity to operate. If electricity is not available (e.g. during a local electricity outage) then your broadband, and any services which run over it, may stop working unless you have battery backup in your home. 

This means services such as landlines, medical alarms, and security alarms may stop working. It is your responsibility to check with the provider of existing services to make sure they will operate under such circumstances. This may also mean you’re unable to contact 111 in an emergency. We recommend having a charged mobile or alternative arrangement in place.

At Mercury, we value customer feedback and take care to address complaints.

Information about our process for customer complaints.

Mercury is a member of the Telecommunications Disputes Resolution (TDR) scheme, a free independent service to help customers resolve broadband disputes.

For more information about TDR, see their website.
