Why This Matters

Broadband Is Now a Utility - As Important as Water or Gas

Before 2020, broadband speed was a convenience. Post-pandemic, it is infrastructure. With over 40% of the UK workforce now working from home at least part of the time, a property without reliable high-speed broadband is functionally unsuitable for a significant proportion of buyers.

The consequences of buying a property with inadequate broadband can be severe: inability to video conference reliably, inability to stream 4K content, reduced property value when you come to sell. For rural properties in particular, ADSL broadband at 5–10Mbps is effectively a dealbreaker for remote workers.

Meanwhile, the UK's full fibre rollout is making connectivity one of the most rapidly changing property attributes. A property that was stuck on ADSL in 2023 may be on a gigabit FTTP connection by 2026. Equally, a property advertised with "superfast fibre" may only have FTTC - not the full fibre (FTTP) that buyers increasingly expect. Our report uses Ofcom's address-level data to give you the precise picture.

UK Broadband Connection Types Explained

FTTP (Full Fibre)

Up to 1Gbps

Fibre to the Premises - the fastest and most future-proof connection. Fibre cable runs directly to the property. Available from Openreach, Virgin Media, and numerous altnets.

FTTC (Fibre to Cabinet)

Up to 80Mbps

Fibre to the Cabinet - fibre runs to the street cabinet; the final stretch to your property uses copper telephone wire. Speed depends heavily on distance from the cabinet.

Cable (HFC)

Up to 1Gbps

Hybrid Fibre-Coaxial - predominantly Virgin Media. Fast and reliable but only available in approximately 50% of UK premises. Consistent speeds unaffected by distance.

ADSL

Up to 24Mbps

Asymmetric Digital Subscriber Line - traditional copper telephone line broadband. Still the only option in some rural areas. Speed degrades significantly with distance from the exchange.

What HouseDossier Checks

Broadband, Mobile & Connectivity - All Covered

Broadband Technology Available

Whether the property can receive FTTP (full fibre), FTTC (fibre to cabinet), cable (Virgin Media), or only ADSL. The technology available largely determines the maximum speed achievable.

Predicted Download & Upload Speeds

Ofcom median predicted download and upload speeds for the specific address - not just an advertised headline figure. Ofcom uses actual performance data from the UK Fixed-Line Broadband Performance Measurement dataset.

Gigabit & Ultrafast Availability

Whether a gigabit-capable (1,000Mbps+) or ultrafast (100Mbps+) connection is available at the specific address - the most important question for home workers and high-demand households.

5G & 4G Mobile Coverage

Outdoor and indoor coverage from EE, Three, O2, and Vodafone at 4G and 5G. Where broadband is weak, strong mobile data coverage may provide a viable backup solution.

How It Works

Your Connectivity Report in Three Steps

01

Enter the property address

We identify the UPRN and query Ofcom's Connected Nations dataset at address level - more precise than postcode-level data, where a single postcode can span properties with very different connectivity.

02

Broadband and mobile data retrieved

Ofcom's address-level broadband availability data is queried, along with mobile coverage data from the four main UK networks. Data is refreshed twice yearly from Ofcom's Connected Nations reporting cycle.

03

Connectivity profile delivered in plain English

You receive a clear connectivity rating: whether the property has full fibre, ultrafast or superfast broadband, with predicted speeds and a mobile coverage summary for all four networks.

FAQ

Broadband & Connectivity - Frequently Asked Questions

Does broadband availability affect property value?
Yes, measurably. Research by Rightmove and Ofcom has found that properties with access to ultrafast broadband (300Mbps+) command a premium of approximately 1.5–5% compared to equivalent properties with only standard broadband. For rural properties where broadband is limited to 10Mbps ADSL, poor connectivity can be a significant deterrent, particularly for buyers who work from home. Since 2020, broadband availability has become a standard question on property searches.
What is the UK Universal Service Obligation for broadband?
The Universal Service Obligation (USO) for broadband, introduced in 2020, gives every UK household and business the legal right to request a decent broadband connection (defined as 10 Mbps download, 1 Mbps upload) at a 'reasonable cost'. If Openreach (or KCOM in Hull) determines the cost of providing the connection exceeds £3,400, the excess can be charged to the customer. The USO is a backstop - most urban and suburban properties already have far faster provision available.
What is the difference between superfast and ultrafast broadband?
Ofcom defines superfast broadband as a connection capable of download speeds of at least 30Mbps. Ultrafast broadband delivers at least 100Mbps download. Gigabit broadband (1,000Mbps) is the fastest tier currently widely deployed in the UK. As of 2024, approximately 80% of UK premises can access superfast broadband, around 77% can access ultrafast broadband, and gigabit availability is at approximately 73%. Rural areas lag significantly behind urban and suburban areas on all metrics.
Can I check broadband speed for a specific address rather than a postcode?
Yes. Our report uses Ofcom's Connected Nations dataset, which is mapped at address level (UPRN) rather than postcode level. This means a property in the middle of a rural postcode that has been recently connected to FTTP will show full fibre availability, even if neighbours at different addresses within the same postcode have not yet been connected.
What mobile coverage data is included?
Our report includes outdoor and indoor mobile coverage data for all four UK mobile networks (EE, Three, O2, Vodafone) at 4G and 5G. Coverage is shown for voice calls and data. Properties in areas with poor indoor mobile coverage may need a signal booster or to rely entirely on WiFi calling - an important consideration for households that use mobile phones as their primary communication device.
Is fibre broadband available in my area?
The UK's full fibre rollout is progressing rapidly. As of early 2025, approximately 73% of UK premises can access gigabit-capable broadband - a significant increase from under 10% in 2019. The government's Project Gigabit programme aims to reach 85% coverage by 2025 and up to 99% by 2030 in harder-to-reach rural areas. Our report shows current availability and, where Openreach has published build plans, may indicate whether FTTP is planned for the address in the near term.
Does broadband availability affect buy-to-let rental demand?
Substantially, yes. Following the shift to hybrid and remote working patterns since 2020, broadband quality has become a primary requirement for professional renters. Properties offering gigabit-capable broadband command higher rents and shorter void periods compared to equivalent properties with only superfast or ADSL broadband. In rural areas, the arrival of full fibre connectivity has been directly correlated with rental and sale price uplifts.
