Is your internet speed actually good?

Netflix and Disney+ both recommend a minimum of 25 Mbps for 4K HDR streaming on a single device. In practice, buffering depends on your connection's sustained throughput rather than its peak speed. If you have multiple devices streaming simultaneously, multiply: two 4K streams need at least 50 Mbps of usable bandwidth. Amazon Prime Video's 4K content typically uses around 15 to 20 Mbps, while YouTube 4K can use anywhere from 15 to 85 Mbps depending on content type.

Online gaming itself uses relatively little bandwidth, typically 3 to 8 Mbps for gameplay data. The real demands come from game downloads and updates, which are large files. A 100 GB game download at 100 Mbps takes about 22 minutes. At 10 Mbps it takes 3.5 hours. For gameplay quality, the critical metric is ping rather than download speed. A 10 Mbps connection with 10ms ping will play significantly better than a 200 Mbps connection with 80ms ping for competitive titles.

UK regulations require ISPs to advertise speeds that at least 50% of customers achieve during peak hours (8pm to 10pm). This means up to half of customers may receive speeds below the advertised figure at peak times. Factors that commonly cause slower-than-advertised speeds include distance from the street cabinet for FTTC connections, the quality of internal wiring, router placement (WiFi signal attenuation), network congestion in your local area, and the service tier your contract provides. If you consistently receive less than 80% of your quoted speed, Ofcom's voluntary code of practice allows you to exit your contract without penalty after notifying your provider.

For most UK households with two to four people, 100 Mbps is comfortably sufficient for simultaneous 4K streaming, video calls, and remote work. The practical ceiling comes from having many devices active simultaneously. A household with four people each running a 4K stream would consume around 100 Mbps, leaving no headroom for other activity. For most families in 2024, 100 to 200 Mbps represents the sweet spot between cost and performance. Gigabit connections offer future-proofing rather than necessary current capacity for the majority of households.

For pre-buffered streaming services like Netflix or YouTube, ping has almost no effect on quality. These services buffer content ahead of playback, so brief latency spikes are absorbed by the buffer. Ping only becomes relevant for streaming in real-time applications: live gaming, video calls, and interactive live streams where delay is perceptible. A ping of 200ms on Netflix will produce the same picture quality as a ping of 5ms. The same 200ms ping on a competitive game like Valorant or Counter-Strike would make the game nearly unplayable.

For a single user browsing the web and streaming HD video, 25 Mbps is sufficient. For a household with multiple people streaming 4K content, gaming online, and making video calls simultaneously, 100 Mbps or more is recommended. The UK national median sits around 70-80 Mbps (Ofcom 2024), while the US median is approximately 200 Mbps (FCC MBA 2024). Whether a speed is "good" depends on your needs: a remote worker uploading large files cares more about upload speed than download.

According to Ofcom's 2024 Home Broadband Performance report, the average UK download speed across all connection types is approximately 100-110 Mbps, while the median sits lower at 70-80 Mbps. The median is more representative of a typical household because a small number of gigabit fibre connections pull the mean upward. Speeds vary significantly by technology: ADSL averages around 10-11 Mbps, FTTC (superfast) averages 36-40 Mbps, and FTTP (full fibre) averages 200-280 Mbps.

For online gaming, ping (latency) matters more than raw download speed. Under 20ms is considered excellent and suitable for competitive first-person shooters. Between 20-50ms is good for the vast majority of online games. Between 50-100ms is playable but you may notice slight delays in fast-paced games. Above 100ms, rubber-banding and input lag become noticeable. Fibre (FTTP) connections typically deliver 5-12ms ping, while ADSL connections average around 25-35ms. Using a wired Ethernet connection often reduces latency more than upgrading your broadband package. (Source: Ofcom 2024)

A VPN routes your traffic through an encrypted tunnel to a remote server, which adds a small amount of latency and can reduce throughput. On a fast broadband connection, a well-optimised VPN using the WireGuard protocol typically reduces download speed by 5-15% and adds 2-10ms of ping. On slower connections, the impact is proportionally larger. For most users on connections above 50 Mbps, the speed reduction is imperceptible during normal browsing and streaming. Choose a VPN server geographically close to you and use the WireGuard protocol if speed is a concern.

For the most accurate results, connect your computer directly to your router using an Ethernet cable, close all other applications and browser tabs, disconnect other devices from the network, and run the test at multiple times of day (morning, afternoon, and evening peak). Use a reputable test like Ookla Speedtest, Fast.com, or your ISP's own speed test. Run at least three tests and take the average. Wi-Fi tests are inherently less reliable because signal strength and interference reduce measured speed. If your Wi-Fi speed is much lower than your wired speed, the bottleneck is your wireless setup, not your broadband. (Source: Ofcom broadband testing guidance)
