A 100Mb broadband connection is widely considered the "sweet spot" for most modern households—fast enough for 4K streaming and working from home, but without the premium price tag of gigabit (1,000Mb+) packages.
Here is a basic guide to finding the best 100Mb broadband deal for your needs.
1. Who is 100Mb broadband for?
Before you switch, ensure this speed tier matches your usage. A 100Mb connection typically supports:
- Medium to large households – Ideal for homes with 3-4+ people using the internet simultaneously
- 4K streaming – Comfortably streams Ultra HD content on multiple devices at once without buffering
- Home working – Provides ample bandwidth for video calls (Zoom/Teams) and large file transfers
- Gamers – Offers fast game downloads and stable latency, though serious competitive gamers might prioritise "symmetric" speeds
2. Typical costs and providers
You should generally expect to pay between £22 and £30 per month for a 100Mb package.
- Budget options – Providers like Onestream, Plusnet, and NOW Broadband often offer the lowest monthly prices, sometimes dipping near the £20 mark
- Major providers – Virgin Media, Sky, BT, and EE are widely available but may cost slightly more unless you catch a special offer
- Challenger networks – If you live in a specific area (like London), providers like Community Fibre or Hyperoptic often beat major networks on both price and speed
3. Upload speeds
Most 100Mb deals are asymmetric, meaning download speeds are fast (100Mb) but upload speeds are much slower (often 20Mb or less).
- Standard uploads (18–100Mbps) – Providers using the Openreach network (Sky, BT, EE, Vodafone) usually cap uploads around this level. This is fine for most users
- Symmetric speeds (100Mbps+) – Providers like Community Fibre, Hyperoptic, and Zen Internet (via CityFibre) often offer "symmetric" connections where upload speeds match download speeds. This is a huge advantage for content creators, YouTubers, or anyone constantly backing up large files to the cloud
4. Key things to check before you buy
- Availability – 100Mb speeds usually require Full Fibre (FTTP) or Virgin Media's cable network. Use a postcode checker first; if you can only get "Superfast" (FTTC) fibre in your area, your speeds will likely max out at around 67Mb
- Contract length – Most deals now lock you in for 18 or 24 months. Shorter 12-month contracts are rarer and often more expensive monthly
- Setup fees – Look for "no upfront cost" deals. Many providers waive setup fees for new customers, but some may charge £5–£30 for router delivery or activation
- New customer incentives – The best value often comes from switching perks. Look for deals including Reward Cards (prepaid Mastercards/Amazon vouchers) or Bill Credit (free months of service)
5. Quick comparison checklist
When viewing a comparison table, ask yourself these three questions to filter the noise:
- Is the price fixed? – Some providers raise prices mid-contract. Fixed-price deals (like some from Trooli, Zen, or Hyperoptic) can save you money in the long run
- Do I need a phone line? – Most 100Mb deals are now "broadband only" (data only), meaning you don't pay extra for landline rental. Only add a phone package if you actually use it
- Is the hardware good? – For 100Mb speeds, you need a decent router. Check if the provider includes a modern Wi-Fi 6 hub (like the Virgin Hub 5 or EE Smart Hub Plus) to ensure you actually get those speeds over Wi-Fi
