UK Broadband with a Landline: Comparing the Cheapest Prices | A Consumer Market Analysis

Comparing the cheapest prices for UK broadband with a landline now requires more than comparing a monthly figure. Most new phone services are delivered through a broadband router, while the traditional public switched telephone network is scheduled for retirement by 31 January 2027. 1

What a broadband and landline package includes

A modern package normally combines an internet connection with a phone number and Digital Voice. The phone service usually connects through the provider’s router rather than a wall socket, and incoming calls may be included while outgoing calls are charged separately unless a calling allowance is added. The distinction matters because a headline broadband charge may not include unlimited calls. 2

Uswitch identifies broadband and home phone packages as a separate comparison category, but notes that many providers now place the phone component on their own websites as an add-on. Broadband-only plans can still include a phone number and digital calling capability, so the presence of a landline does not automatically mean a separate line-rental charge. 3

Typical monthly price patterns

Research published in 2026 places ordinary broadband and phone bundles at around £22.50 per month at the lower end, while budget fibre connections with a phone service are generally described in the £22 to £30 range, depending on speed, contract term and location. These figures are category expectations rather than guaranteed prices at every address. 4

The phone element can materially change the total. A paid calling bundle commonly adds about £6 to £10 per month, usually in exchange for evening and weekend calls, anytime UK calls, or allowances that also cover mobiles and international destinations. For light users, pay-as-you-go calling may have a lower total cost; for regular users, the allowance can become more economically significant. 2

Providers and availability

Availability is address-specific because fibre networks differ between postcodes. Uswitch’s comparison process begins with a postcode, and its August 2026 results show starting prices from £35.99 for several speed bands, with faster categories beginning at £39.99 for 300 Mbps and £41.99 for 900 Mbps. Such figures demonstrate why speed and network coverage must be assessed alongside the phone component. 3

TalkTalk, Plusnet and other established providers have historically occupied the lower-cost end of combined broadband and phone pricing, but package structures change frequently. A comparison should therefore record the introductory monthly charge, the post-contract charge, annual increases, activation or equipment costs, call rates and the exact minimum term rather than relying on a provider’s brand reputation. 5

Social tariffs and landline-only alternatives

Households receiving qualifying benefits may be able to access social tariffs. The research identifies BT, Virgin Media and Hyperoptic as providers with social-tariff arrangements, commonly in the approximate £12 to £20 monthly range, subject to eligibility and the individual provider’s conditions. These tariffs are not general market prices and may involve specific benefit evidence, speed limits or package restrictions. 6

Standalone landline services remain available in limited circumstances. Choose reports that KCOM in Hull has a landline-only service at £11.99 per month, while BT’s comparable figure across most of the UK is £13.09. Social versions are identified at £5.10 from KCOM Flex and £10 from BT Home Essentials, although regional availability and qualification rules apply. 7

Calling costs, contracts and price rises

The apparent monthly price is only one part of the calculation. A household should establish whether calls to mobiles, international numbers, premium-rate numbers and directory services are excluded, and whether the allowance is subject to fair-use limits. Research on broadband phone bundles places the approximate break-even point for an inclusive calling option at about 100 minutes of outgoing landline calls per month, though actual results depend on the provider’s rates. 2

Contract length is another source of friction. Two-year terms are common, and leaving early can trigger termination charges. Some providers apply annual or mid-contract increases, including rises described in the research as approximately £3 to £4 after the first year. A meaningful comparison should calculate the expected total over the full term instead of multiplying only the initial monthly amount. 8

Digital Voice risks and practical checks

Digital Voice depends on household electricity and broadband connectivity. Unlike a traditional copper phone, it may not work during a power cut unless battery backup or another contingency is provided. The research also states that all UK landlines are moving to IP-based services by 31 January 2027, so the principal change concerns the phone technology rather than the broadband connection itself. 1

Extra checks are necessary where a home uses a care alarm, telehealth pendant, monitored security system or another device connected to the phone line. Compatibility should be confirmed with the device manufacturer before changing service. Number retention also requires care: Openreach-based switching can preserve an existing number, but cancelling the old service before the transfer is initiated can jeopardise that process. 1

How to compare the total household cost

A structured comparison begins with the required download speed and then separates internet charges from phone charges. The relevant record should include the typical speed, data limits, router conditions, calling allowance, call rates, contract duration, annual increases and any one-off charges. Customer service and reliability also matter because a lower monthly figure may be poor value if the service does not meet household requirements. 3

• Identify whether the phone service is included, optional or unavailable.
• Compare pay-as-you-go calling with the cost of an inclusive allowance.
• Check eligibility rules for social tariffs before treating them as general prices.
• Confirm number transfer arrangements and equipment compatibility.
• Assess power-cut arrangements for vulnerable households and care devices.

The overall market is moving away from the idea of a separately rented copper telephone line. For many households, the relevant choice is now between broadband with basic Digital Voice and broadband with a paid calling allowance. The financially meaningful comparison is therefore the complete contract cost, including expected calls, price changes, technical requirements and early-exit exposure. 2
