Openreach

Openreach is the UK’s largest broadband network operator, inherited from BT. They provide wholesale broadband infrastructure to ISPs across the UK, delivering both FTTC and FTTP services to ~98% of premises.

Switching broadband provider saves the average household around £156 a year, according to Ofcom, and most providers now handle the switch for you.

• FTTC (Fibre to the Cabinet): Available.
• FTTP (Full Fibre): Expanding nationwide, speeds up to 1 Gbps
• Wholesale model: ISPs buy capacity and resell to customers
• 97% of UK premises passed by Openreach infrastructure

The infrastructure behind most UK broadband. Your actual experience depends heavily on which retail provider sits on top of the network.

What Openreach Does (And Doesn’t Do)

Openreach builds and maintains the UK’s largest broadband network, fibre and copper infrastructure serving 30 million premises. It’s a separate company from BT, though historically related. Openreach crucially doesn’t sell to consumers. You can’t sign up with Openreach directly. Instead, retail providers (BT, Sky, Plusnet, TalkTalk, others) purchase wholesale access to Openreach’s network. When you experience problems, your engineer has an Openreach van, your retail provider subcontracts to Openreach for installation and support. Understanding this matters when complaining. If BT provides poor service, BT is responsible. If Openreach installs badly, BT handles your complaint but relies on Openreach to resolve the underlying issue. Openreach’s network quality is generally good, they’re constantly upgrading infrastructure. The challenge arises when retail providers’ poor support masks good underlying Openreach infrastructure.

Openreach Full Fibre: The UK’s Biggest FTTP Rollout

Openreach is deploying full fibre FTTP to 25 million premises by 2026, the UK’s largest broadband modernisation programme. Rollout prioritisation balances demand (areas with strong political pressure) and geography (efficient build routes). Urban and suburban areas roll out faster. Rural areas see slower deployment due to infrastructure costs. Rural premises sometimes waiting until 2026 or beyond. The UK government provides funding to accelerate rural rollout through Project Gigabit. If your street hasn’t been upgraded, you can’t force deployment faster. However, you can check your estimated upgrade date on the website. Some areas have specific announced dates. Others show ‘no date available,’ suggesting no current plan. If that’s your situation, investigate government upgrade schemes or alternative providers.

Key Factors to Consider When Comparing

Speed alone isn’t the only metric. Look at upload speeds, which matter increasingly with video conferencing and cloud storage. Check latency (ping time) if you game or use video calls extensively. Examine contract flexibility, are you locked in for 24 months or can you switch monthly? Don’t ignore customer satisfaction ratings. Independent reviews reveal service quality beyond marketing claims. Check specific reviews for your postcode to understand real world performance. Consider whether the provider includes a new router or charges separately. Installation fees vary significantly. Some offer free installations; others charge £50–150. Check if you’re eligible for any switching incentives or loyalty discounts. Calculate the total cost over the full contract period, including setup fees, rather than focusing only on monthly costs. Price comparisons can be misleading if they ignore these extras.

Understanding Your Broadband Speed Results

You signed up for ‘up to’ 100Mbps but you’re getting 60Mbps. Is that normal? Yes, ‘up to’ speeds are marketing maximums, not guarantees. Real world speeds depend on network congestion, distance from exchange (for FTTC), WiFi signal strength, and time of day. Download a speed testing app and test during off peak hours (midday weekdays) versus peak hours (6–9 PM evenings). Peak hour speeds should still meet your Minimum Guaranteed Access Speed (MAP). If they fall short, contact your provider to report faults. Use multiple speed tests, single tests can be misleading due to temporary congestion. Test on wired connection versus WiFi to identify WiFi issues separately. Expect variations of 10–15% around advertised speeds as normal. Consistent speeds 30%+ below advertised warrant complaint to your provider.

Cost Comparison: Total Contract Cost vs Monthly Price

A provider advertising £20/month might actually cost more than one advertising £25/month. The difference? Hidden charges. A £20/month deal might include £80 setup fee, £10/month router rental, and annual price rises reaching £35 by month 12. A £25/month plan might have £0 setup, included router, and price lock. Total 2 month cost for the first: £20×12 + £32×12 + £80 = £704. Total for the second: £25×24 = £600. The cheaper monthly offer cost you £104 more overall. Always calculate total cost including all fees over the full contract period. Many people make switching decisions based on misleading comparisons. Use a calculator entering exact fees to compare accurately. Don’t trust advertised monthly rates alone.

Switching Process: What Actually Happens

Day 1: You sign up online or phone the new provider. Day 2–3: New provider contacts your existing provider to notify of the switch. Your current provider confirms disconnect date (typically 7–14 days away). Day 5–7: New provider arranges installation engineer visit. Day 7–10: Engineer installs new broadband service at your home. Day 10–14: Your previous broadband disconnects automatically. Throughout the process, you maintain broadband, no period without service if switching properly. The new provider provides a migration code so you keep your phone number (important if you have landline). Your old provider may contact offering retention discounts. These sometimes beat new provider offers. You have 14 days to cancel if unsatisfied. Most providers offer money back guarantee within this cooling off period. Keep documentation of what you signed up for in case disputes arise.
