Checking Broadband Before Buying: Speed, Fibre, and What to Expect

According to Ofcom's latest Connected Nations report, approximately 6% of UK premises still cannot access a "decent" broadband connection of at least 10 Mbps download speed — and even among those that can, speeds vary dramatically from property to property. At HouseCheckup, our £24.99 property reports include broadband speed data and availability information for any address, helping buyers understand connectivity before they commit to a purchase. With 4.2 million people now regularly working from home (ONS data), broadband has become a material factor in property decisions.

Why Broadband Matters for Property

Broadband connectivity has evolved from a nice-to-have to a genuine property value driver. Research by Rightmove found that 32% of home movers ranked broadband speed as a "very important" factor in their property search — ahead of local transport links and proximity to shops. For remote workers, inadequate broadband can render a property unworkable, regardless of its other merits.

Broadband and Property Value

Studies have shown that properties with access to superfast broadband (30 Mbps+) command a 2–3% premium compared to equivalent properties without. For ultrafast connections (100 Mbps+), the premium increases to 3–5%. Conversely, properties in broadband "not-spots" can sell for 5% or more below comparable connected homes.

Understanding Broadband Speeds

Broadband speeds are quoted in Megabits per second (Mbps). Here's what different speeds actually mean in practice:

What Speed Do You Actually Need?

The speed you need depends on your household's usage patterns. As a rule of thumb:

• Video call (Zoom/Teams): 5–10 Mbps per simultaneous call
• HD streaming (Netflix, iPlayer): 5–8 Mbps per stream
• 4K streaming: 25 Mbps per stream
• Online gaming: 10–25 Mbps (latency matters more than speed)
• Large file uploads (WFH): Upload speed of 10+ Mbps

For a typical family of four with two adults working from home, a reliable 80–150 Mbps connection is ideal. Remember that advertised speeds are "up to" figures — actual speeds are often 50–80% of the headline number, especially during peak times.

Types of Broadband Connection

ADSL / ADSL2+

The oldest broadband technology, delivered over standard copper telephone lines. Maximum speed of approximately 10–17 Mbps, heavily dependent on distance from the telephone exchange. Properties more than 3km from the exchange may get under 5 Mbps. Being phased out as fibre networks expand.

FTTC (Fibre to the Cabinet)

Fibre optic cable runs to the green street cabinet, then copper wire carries the signal to your property. Maximum speed of approximately 40–80 Mbps, depending on the distance from the cabinet to your home. This is the most common "superfast" broadband in the UK, available to around 96% of premises.

FTTP (Fibre to the Premises / Full Fibre)

Fibre optic cable runs directly into your property, eliminating the copper bottleneck. Speeds of 100 Mbps to 1 Gbps+ are typical. Currently available to approximately 60% of UK premises (Ofcom data), with ongoing rollout by Openreach, Virgin Media, CityFibre, and smaller alt-nets. This is the gold standard.

Virgin Media (Cable)

Virgin Media operates its own coaxial cable network, offering speeds of 50 Mbps to 1.1 Gbps. Coverage is approximately 52% of UK premises, concentrated in urban and suburban areas. Performance can degrade during peak hours due to shared bandwidth in the local network.

Fixed Wireless / 5G Broadband

Wireless broadband using 4G or 5G networks. Speeds vary from 30 Mbps to 300+ Mbps depending on signal strength and network congestion. Useful for rural properties where wired connections are poor, but reliability can be affected by weather and network load.

How to Check Broadband at a Property

1. Ofcom checker: The official broadband and mobile coverage checker shows what's available at any UK address
2. Openreach fibre checker: Shows whether FTTP or FTTC is available or planned for the address
3. Provider checkers: BT, Sky, Virgin Media, and others let you check availability and estimated speeds at a specific address
4. HouseCheckup report: Our £24.99 report includes broadband speed data alongside all other property checks
5. Ask the seller: Request a recent speed test result. The TA6 property information form requires sellers to disclose broadband information

The BDUK and Universal Service Obligation

The UK has a Universal Service Obligation (USO) giving every household the legal right to request a "decent" broadband connection (10 Mbps download, 1 Mbps upload). If your property can't get this speed, BT (as the designated Universal Service Provider) must provide a connection at no cost to the customer if the installation cost is below £3,400. Above this threshold, the customer pays the excess.

The government's Project Gigabit programme is investing £5 billion to bring gigabit-capable broadband to hard-to-reach areas, targeting 85% gigabit coverage by 2025 and near-universal coverage by 2030.

Rural Broadband Challenges

Rural properties face the biggest broadband challenges. If you're considering a rural purchase, check:

• Whether the property is included in any planned fibre rollout (Openreach or alt-net)
• 4G/5G signal strength at the property (use Ofcom's coverage checker)
• Satellite broadband availability (Starlink offers 50–200 Mbps in most UK locations)
• Community broadband schemes — some rural communities have funded their own fibre connections

Check Broadband Before You Commit

A HouseCheckup report for just £24.99 includes broadband speed data and availability alongside flood risk, EPC, planning history, and dozens of other property checks. Don't discover after moving in that your dream cottage has 3 Mbps broadband and no mobile signal. At £24.99, our report ensures you understand connectivity before you commit — because in the remote working age, broadband speed is as important as the number of bedrooms.
