Check gigabit and superfast broadband availability, plus 4G and 5G mobile network coverage, for any UK address before committing to a location.
Updated: periodically, aligned with Ofcom's Connected Nations reporting · Last checked by Maplify: July 2026
This layer maps Ofcom connectivity data: gigabit-capable broadband (full fibre and cable, 1000+ Mbps), superfast broadband (30+ Mbps via fibre-to-the-cabinet), and 4G/5G mobile coverage from EE, Vodafone, O2 and Three. Gigabit broadband now reaches around 79% of UK premises, with superfast reaching roughly 97%.
Digital exclusion areas below the Universal Service Obligation threshold are also flagged, relevant to Project Gigabit funding eligibility and alternative connectivity solutions.
Connectivity affects both day-to-day usability of a property — particularly for remote working — and, since 2022, new-build compliance obligations. Buyers and developers check this layer to confirm realistic broadband speeds and mobile coverage before committing to a location, rather than relying on generic marketing claims from providers.
For rural sites specifically, checking both broadband and mobile coverage together identifies whether a 4G/5G home broadband fallback is viable if fixed-line speeds prove insufficient.
Gigabit broadband
Full fibre or cable connection capable of 1000+ Mbps — available to around 79% of UK premises.
Superfast broadband
Fibre-to-the-cabinet connection of 30+ Mbps — available to around 97% of UK premises.
4G / 5G mobile coverage
Predicted network coverage from the four major UK mobile operators.
Building Regulations Part R (2022) requires new homes to have a gigabit-capable broadband connection, with developer-funded infrastructure required where the connection cost falls under a set threshold. This applies to most new residential development and should be factored into site infrastructure costs from the outset.
For sites in digitally excluded areas, developers may need to coordinate with network operators or Project Gigabit funding to secure adequate connectivity for a scheme.
Confirm exact broadband tier and mobile coverage with Ofcom's official checker for the specific address.
For new development, budget for gigabit-capable infrastructure under Building Regulations Part R.
Check Project Gigabit funding eligibility for sites below the Universal Service Obligation threshold.
Consider 4G/5G home broadband as a fallback for rural sites with limited fixed-line speeds.
Check the wider Transport Infrastructure layer for the same site for the fuller connectivity and access picture.

How do I check broadband speed for a property?
Search the property address on Maplify and enable the Gigabit Broadband and Superfast Broadband layers to see which speed tiers are available there, then verify exact speeds with individual providers.
What is the Universal Service Obligation?
The USO gives UK premises a legal right to request a 10Mbps+ broadband connection if nothing faster is commercially available, with BT/Openreach required to provide it at a capped contribution cost of £3,400.
Does this map show exact broadband speeds or just availability?
It shows availability of gigabit, superfast and other broadband tiers for an area. Actual achievable speed depends on factors like distance from the cabinet — always confirm exact speeds with the provider.
How reliable is rural mobile coverage data?
Coverage layers show predicted coverage from network operators, which can differ from real-world performance indoors or in sheltered locations.
Do new homes have to include gigabit broadband?
Yes. Building Regulations Part R (2022) requires new homes to have a gigabit-capable broadband connection, with developer-funded infrastructure required where the connection cost is under a set threshold.
Search any UK address to see broadband and mobile coverage alongside planning and property data.
