What Is AltNet Broadband?

AltNet (alternative network) broadband refers to full-fibre internet built and operated by independent providers, separate from Openreach's national network. These smaller providers have been rolling out fibre in areas that larger providers have been slower to reach, including many rural and semi-rural communities, often bringing full-fibre connections to properties years ahead of Openreach's own rollout plans.

Advantages of AltNet broadband:
  • Faster access to full-fibre - AltNets frequently target underserved rural areas first, meaning some properties can get full-fibre broadband before Openreach infrastructure arrives locally.
  • Competitive pricing - With fewer overheads than larger national providers, AltNets can sometimes offer competitive rates, particularly for full-fibre packages, making them a better choice in some areas.
  • Dedicated local infrastructure - Many AltNets build their own independent fibre network rather than reselling existing infrastructure, which can mean more reliable, uncongested connections.
  • Community-focused rollout - Some AltNets specifically prioritise rural and hard-to-reach communities as part of their business model, rather than treating them as a lower priority.

Why Choose an AltNet Over a Standard Provider?

For many rural households, the decision to switch to an AltNet often comes down to availability. An AltNet provider may roll out full-fibre broadband in a specific area years ahead of the schedule set by larger national providers. But cost and service quality can play just as big a role, particularly for households who've grown used to inconsistent speeds or ongoing line issues with older copper-based connections.

Consider a household in a small village that has relied on an ageing FTTC connection for years, with speeds dropping noticeably during peak evening hours and repeated faults following winter storms. When a local AltNet begins installing full-fibre lines in the area, the household finds they're not only offered significantly faster and more stable speeds, but often at a comparable or lower monthly cost than their existing package. Because the AltNet has built its own independent fibre infrastructure rather than relying on the ageing local exchange, the connection is less prone to the congestion and weather-related faults that affected their previous service.

Factors that might be Slowing your Existing Broadband Connection

Several factors can influence how fast and reliable your broadband connection feels at home, even if you’re on a fast package.
  • Connection type - Full fibre delivers the fastest, most consistent speeds, while older copper-based connections (FTTC/ADSL) are more limited and prone to slowdown.
  • Distance from cabinet or exchange - The further a rural property is from local infrastructure, the more speeds can drop, particularly on copper lines.
  • Overhead vs underground lines - Overhead lines, more common in rural areas, are more exposed to weather damage and general wear.
  • Number of properties sharing the connection - Fewer properties per exchange can help, but ageing or lower-capacity infrastructure can offset this benefit.
  • Local terrain and geography - Hills, dense woodland, and long cable runs can affect signal strength and reliability, particularly for wireless or mobile-based broadband.
  • Router placement - Poor placement can weaken the Wi-Fi signal around your home.
  • Connected devices - More devices online means less bandwidth available per user.
  • Time of day - Shared local infrastructure can slow down during busy evening periods when more households are online.
  • Weather conditions - Storms, high winds, and flooding can disrupt overhead lines or damage cabinets, causing temporary drops in speed or outages.

Average, download and upload speed ranges show you estimated speed at the busiest time of day (8pm to 10pm). Broadband speed could even faster outside of those times. Broadband speed can fluctuate over the day, and this happens for many reasons, including the number of customers using the network at the same time. Speeds are based on the broadband speed you get to your router. The speed you get on your devices over Wi-Fi or cable might be slower.

Minimum download speed is the slowest the speed connection to your router should ever drop to. If your connection is slower, some providers may give you compensation of offer you the right to leave your contract penalty free. If you are having problems with your connection, get in touch with your provider to see what their policy is.
