Understand the difference.

01 / THE ROUTE TO THE PREMISES

Not every broadband connection is built the same way.

Full fibre, also called FTTP, runs optical fibre to the premises. Part-fibre services typically retain a copper section for the final connection. Cable networks use a different access infrastructure, while alternative fibre networks may bring another route to the same street. Availability is specific to the property, not simply the town.

A retail provider and an access network are different parts of the service. Two packages sold under different brands may depend on the same underlying network. Conversely, a property may have access to more than one physical network. Ask which access route an offer uses and whether another route changes the speed, installation or resilience of the proposal.

Where fixed services are limited, fixed wireless, 4G/5G or satellite may merit investigation. Signal, capacity, equipment location, latency and installation constraints matter. Treat a technology category as a possible route to research, rather than proof that it is available at your address.

Openreach’s official fibre checker distinguishes services available to order from planned construction. A planned network is useful context, but it is not an orderable connection.

02 / PERFORMANCE IN PRACTICE

Download. Upload. Response time. Three useful questions.

Download speed affects how quickly data arrives. Upload speed matters when sending large files, synchronising cloud backups, publishing video or supporting many simultaneous calls. Latency describes response delay; a faster headline download rate alone does not promise a lower delay for every application.

Record the problem before changing the service. Is the slowdown present on a wired connection? Does it happen throughout the day, or mainly when many people are online? Does only one room struggle? Weak Wi-Fi coverage, old equipment, device limitations and a congested service are different problems with different remedies.

Ask for the supplier’s address-specific estimates and the terms that apply to them. Ofcom notes that its checker shows predicted network speeds and that actual availability and received speeds can differ. Use that information as a starting point, then confirm the offer for the exact premises.

The transfer calculator illustrates an ideal relationship between file size and connection rate. It does not measure a line or account for every device and application constraint.

03 / THE FULL COMPARISON

Compare the service over the period you expect to keep it.

Place setup, installation and equipment costs next to monthly charges. Check the minimum term, any stated future price changes, service changes after a promotional period and the process for leaving. Compare the total proposal using the same period and assumptions; a small first-month price is not a complete cost comparison.

Consider what the package includes: router suitability, support arrangements, upload performance and any telephone service you need. If you rely on alarms, telecare equipment or other devices connected to an existing phone service, discuss their compatibility before changing access. Keep any number-retention requirement in the brief.

04 / WORK THAT CANNOT WAIT

Resilience is a design decision.

A business may need a second access route, managed failover, appropriate support or a dedicated service. A leased line and a shared broadband package should be compared against their actual commercial and technical terms, not assumed to offer the same service simply because their advertised rates look similar.

Two connections do not automatically provide independent resilience. Ask about shared ducts, local power, equipment, upstream dependencies and how failover is tested. Document who monitors the service and who takes responsibility when it fails. Keep an operational fallback for critical work.

For several premises, include every address, the traffic between sites and any cloud systems or voice services that need to remain reachable. Related projects can help frame a wider brief: bandwidth optimisation and global connectivity sourcing.
