Methodology and data sources

What FibreSwitch is and is not

FibreSwitch is a comparison service. We do not provide broadband service, and we do not control network coverage or installation timelines.

We show what is available at your address based on postcode and provider data, then surface key terms so you can compare offers consistently.

What availability means

Availability is checked at postcode and address level because networks can vary by street, building, or property type.

You should always run a postcode check for the exact property you plan to connect.

How results are ranked

Ranking is based on the pricing and terms shown for your address. Availability always comes first.

Read the detailed ranking explanation at /how-results-are-ranked/.

How we make money

We may earn commission when a switch completes. This does not change availability or eligibility.

See the detailed explanation at /how-we-make-money/.

What to double-check at checkout

• Contract length and any early exit fees.
• Price rises or mid-contract increases shown.
• Setup fees, engineer visit notes, and router delivery.
• Estimated vs guaranteed minimum speeds.

Personal data used in the checker

The postcode checker uses your postcode and address to confirm availability. We do not publish or share personal addresses.

See /privacy/ for the full privacy policy.
