Mobile Data vs Home Broadband
Our broadband and mobile bundle calculator estimates the total monthly cost and potential saving from combining your home broadband and mobile phone contract with the same provider. Many UK operators offer significant discounts for customers who take both services together — though the saving should always be compared against best-of-breed standalone deals.

Broadband and Mobile Bundles in the UK
Major telecoms providers — including Virgin Media O2, Sky, BT/EE, and Vodafone — offer combined broadband and mobile contracts. The typical saving for combining both services ranges from £5 to £20 per month versus buying the same products separately from the same provider. However, standalone providers may still produce a lower combined total even without a bundle discount. The key question is whether the bundle price beats the sum of the cheapest separate broadband deal plus the cheapest mobile deal. Use our Broadband Savings Calculator to check the broadband component separately, and our Broadband Exit Fee Calculator if you are mid-contract on any bundle element.
Frequently Asked Questions
Yes — mobile number portability allows you to transfer your existing number to any UK network. Request a PAC code from your current provider and provide it to the new network. Porting typically completes within 1 working day.
A SIM-only contract provides the mobile service without a handset. Handset contracts include the phone cost spread over the contract term. SIM-only is almost always better value if you already own a recent phone or buy your handset outright.
Some bundles require both elements to be on the same contract term — typically 24 months. If you need to end one element early, exit fees may apply to both components. Always check the exit fee for each part before signing.
Post-Brexit, EU roaming charges have been reintroduced by some providers. Check whether your bundle mobile plan includes EU roaming and at what data speeds. Unlimited UK plans with restricted EU roaming are common.
If you move mid-contract, the broadband service must be transferred to the new address (if available) or the bundle exits on agreed terms. Moving to an area not covered by your broadband provider may allow exit without an early termination charge.
Enter your current broadband and mobile contract costs separately, then the cost of the combined bundle being considered. Network operators and ISPs increasingly offer combined home broadband and mobile SIM deals with meaningful discounts versus buying separately. The calculator shows total annual cost of the separate versus bundled approach and the saving over the bundle contract length. Consider service quality for both components independently — a cheaper bundle is not worthwhile if broadband speed is insufficient or mobile signal is unreliable in your area. Check whether the bundle can be separated if one component becomes unsatisfactory: some bundles tie both services to a single contract that cannot be cancelled partially.
