Broadband speed is one of the most searched topics among remote workers in the UK — and yet the answer most people find is either too vague to be useful, or focused only on download speed while ignoring upload. For home workers, both directions matter equally. A video call is a two-way stream, and it is your upload speed that determines how others see and hear you.
This guide gives specific, practical speed recommendations for every type of home working scenario — from light occasional use to full-time professionals on back-to-back calls — along with an honest assessment of whether your current broadband technology is actually up to the job.
Most broadband packages are marketed primarily on download speed, and that is the figure that dominates comparison tables. But for home workers, upload speed is equally — and in some cases more — important.
Download speed affects how quickly data comes to your device: loading web pages, watching video content, pulling files from cloud storage, streaming a colleague's screen share.
Upload speed affects how quickly data leaves your device: your video and audio on a call, uploading files to shared drives, sending large email attachments, backing up to cloud storage.
On older FTTC (fibre to the cabinet) connections, upload speeds are typically much lower than download — often 10–20 Mbps even on packages with 80 Mbps download. This asymmetry is fine for households that primarily consume content, but it is a practical constraint for home workers who need to transmit data consistently throughout the day. Full fibre (FTTP) connections offer near-symmetric or symmetric upload and download speeds, which is one of the primary reasons they are better suited to home working.
Different work tasks place different demands on your connection. The following gives specific figures for the most common home working scenarios:
| Task | Min. download | Min. upload | Notes |
|---|---|---|---|
| Email, browsing, documents | 10 Mbps | 5 Mbps | Any broadband connection is sufficient |
| 1-to-1 HD video call | 10 Mbps | 5–10 Mbps | Stable connection more important than raw speed |
| Group video call (HD) | 25 Mbps | 10–20 Mbps | Multiple streams increase upload demand |
| Screen sharing | 15 Mbps | 10 Mbps | Upload drives quality when you are sharing |
| Cloud storage sync (Google Drive, OneDrive) | 10 Mbps | 10–50 Mbps | Upload speed determines sync time for large files |
| Large file transfers (design, video) | 50 Mbps | 50 Mbps+ | Full fibre significantly reduces transfer times |
| VPN connection to office network | 25 Mbps | 10 Mbps | VPN adds overhead — headroom above minimum is wise |
These figures apply to a single task running alone. In practice, multiple tasks run simultaneously — your cloud backup syncing in the background while you are on a video call, for example. Always add headroom above the minimum for any individual task.
Your broadband speed requirement is not just about your own work tasks — it depends on everything else happening on your network simultaneously. Other household members streaming, gaming, or attending their own calls all consume bandwidth from the same shared connection.
| Household | Recommended download | Recommended upload | Suggested technology |
|---|---|---|---|
| Single home worker, light use | 50 Mbps | 20 Mbps | FTTC or entry FTTP |
| Single home worker, heavy calls and cloud | 100 Mbps | 50 Mbps | FTTP |
| Two home workers, simultaneous calls | 150–200 Mbps | 100 Mbps | FTTP |
| Home worker + family (streaming, gaming) | 200–300 Mbps | 100 Mbps | FTTP |
| Power user / large file transfers daily | 500 Mbps+ | 200 Mbps+ | FTTP (500 Mbps or Gig1) |
The three dominant video call platforms have each published their own bandwidth recommendations. These are the minimums for the platform to function — not the speeds at which it functions well, with headroom for other simultaneous network activity.
Zoom recommends 600 Kbps download and upload for a 1-to-1 HD video call. For group calls in HD, it recommends 2.5 Mbps download and 3 Mbps upload. For 1080p Full HD group video, the recommendation rises to 3.8 Mbps download and upload. In practice, these are minimum figures — a stable 10 Mbps upload provides comfortable headroom for HD group calls.
Microsoft recommends 1.5 Mbps both ways for peer-to-peer HD video, and 4 Mbps download / 3 Mbps upload for group calls. Teams also places additional load on connections when combined with SharePoint sync, OneDrive backup, and other Microsoft 365 services running simultaneously — making upload headroom more important than the call figures alone suggest.
Google recommends 3.2 Mbps download and 1.8 Mbps upload for HD group video. For 720p video it requires 2.6 Mbps download and 1.8 Mbps upload. These are among the lower requirements of the major platforms, which is why Meet tends to perform relatively well on slower connections.
The practical takeaway: the platforms themselves do not need enormous bandwidth. The problem arises when your connection is already partially consumed by other devices or processes, leaving insufficient headroom. A 20 Mbps upload on a full fibre connection handles any of these platforms comfortably — even with background processes running.
Cloud-based work tools — Google Workspace, Microsoft 365, Slack, Notion, Figma, and others — place continuous background load on your connection rather than the burst demand of a file download. This constant low-level activity is largely invisible but accumulates. On a slow or congested connection, it manifests as sluggish application response, delayed document syncing, and lag in collaborative tools.
File transfers are where upload speed becomes viscerally noticeable. Uploading a 1 GB video file to a shared drive:
For professionals who routinely transfer large files — designers, video editors, architects, marketers working with high-resolution assets — the upload speed difference between FTTC and FTTP translates directly into hours of recovered time each week.

Compare by PostcodeFor light home working — occasional emails, document editing, and one or two video calls a day — FTTC is generally workable. But for anyone whose work is primarily conducted over a screen with regular video calls, cloud collaboration tools, and file sharing, FTTC has two structural limitations:
FTTC packages typically deliver 10–20 Mbps upload even on the fastest 80 Mbps download tiers. This is a hard ceiling imposed by the copper infrastructure — you cannot get more upload speed by upgrading to a faster FTTC package. For a single light user this is adequate; for anyone on frequent group video calls or uploading large files regularly, it becomes a bottleneck.
FTTC infrastructure shares capacity among multiple premises. During peak hours — particularly weekday mornings and afternoons when video call traffic is highest — available bandwidth per household reduces. This manifests as degraded video quality, dropped calls, and sluggish cloud application response at exactly the times when you most need the connection to perform.
Full fibre (FTTP) addresses both issues. Its infrastructure has significantly greater capacity, and the symmetric or near-symmetric upload/download speeds remove the upload bottleneck entirely. If FTTP is available at your address, upgrading is the single most impactful change you can make to your home working broadband.
Knowing your theoretical package speed is useful — but your real-world speed during working hours is what matters. Here is how to get an accurate picture:
If switching to a faster package or provider is not immediately possible, these steps can meaningfully improve your current broadband performance for home working:
Connecting your work device directly to the router via an Ethernet cable eliminates Wi-Fi interference and variability. This is the single most reliable improvement for home workers on any connection type. A Cat 6 cable costs a few pounds and can be run along skirting boards or under carpet if needed.
On FTTC connections, plugging your router directly into the master socket (the first socket where the phone line enters your home) rather than a secondary extension can improve speeds by reducing line interference. Look for a socket with a horizontal line across the front plate.
Many modern routers allow you to prioritise certain devices or traffic types — such as your work laptop or video call applications — over other network activity. Check your router's admin settings (usually accessible at 192.168.0.1 or 192.168.1.1) to see whether QoS is available.
Large file transfers and cloud backups that run during video calls consume upload bandwidth that those calls need. Scheduling these for evenings or early mornings — when the connection is not needed for work — removes the conflict.
The router supplied by your ISP is often modest hardware. If you are not getting speeds close to your package's headline rate over Wi-Fi, a third-party router or mesh Wi-Fi system may improve real-world performance — particularly in larger properties where a single router cannot cover all rooms effectively.
For a single home worker on video calls and cloud applications, 50–100 Mbps download and at least 20 Mbps upload is advisable. For households with multiple simultaneous users, 150–300 Mbps on a full fibre connection provides comfortable headroom. Upload speed matters as much as download for home workers.
The major platforms recommend 1.5–3.8 Mbps upload for HD group video calls. In practice, 10–20 Mbps upload provides comfortable headroom for simultaneous calls, background cloud sync, and other devices on the network. FTTC's 10–20 Mbps upload ceiling becomes a bottleneck for frequent callers; FTTP removes this constraint.
For light home working, yes. For professionals on frequent video calls or using cloud-intensive tools, FTTC's low upload speeds and susceptibility to peak-time congestion become real limitations. Full fibre is the better choice for home workers where available.
The most common causes are insufficient upload speed, peak-time network congestion on FTTC, Wi-Fi interference, or other devices consuming bandwidth simultaneously. Connecting via Ethernet and upgrading to full fibre addresses most of these issues.
For most remote employees and freelancers, a good residential full fibre package is sufficient. Business packages offer enhanced fault resolution SLAs and static IPs — relevant for businesses hosting services or running VPNs, but not necessary for most home workers.
