For restrictive networks, OpenVPN TCP/443 is robust. Otherwise, WireGuard (UDP) is faster.

Best VPN Settings (UK, 2025) — Speed, Streaming & Privacy

Q: What’s the single best setting for speed?

Use WireGuard on a nearby UK server, Ethernet where possible, and minimise background traffic.

Q: Do I need split tunneling?

Optional, but handy to keep banking/work apps outside the tunnel while streaming via VPN.

Q: How do I know if DNS is leaking?

Run an extended leak test; you should not see your ISP resolvers. Follow our UK leak guide for steps.

Copy-paste presets that work on UK broadband and 5G — with streaming and privacy tweaks.

TL;DR presets (UK)

✅

Default daily use: WireGuard/NordLynx → nearest UK server (London/Manchester/Birmingham) → kill switch ON → DNS leak protection ON.

✅

Restrictive networks (office/public Wi-Fi): OpenVPN TCP/443 → rotate UK server → relaunch app after changes. See protocols guide.

✅

Streaming stability: rotate UK endpoints if you see proxy errors → relaunch Netflix/iPlayer → try OpenVPN TCP/443 as fallback. Guides: Netflix UK, iPlayer.

✅

Smart TV / consoles: consider a router VPN for whole-home coverage. Start here: Router setup (UK).

Protocols: when to use which

WireGuard / NordLynx — fastest on UK broadband/5G; minimal CPU load; first choice.
OpenVPN TCP/443 — disguises as HTTPS; great on captive portals and strict networks (libraries, campuses, corporate Wi-Fi).
IKEv2 — very stable on iOS while roaming; not ideal for tricky firewalls.

Deep dive and pros/cons: WireGuard vs OpenVPN vs IKEv2 (UK).

Core privacy settings

Kill switch: ON. Should block traffic on drops (test once by killing the app).
DNS leak protection: ON. All DNS must resolve inside the tunnel — verify with our leak checks guide.
Auto-connect: ON at boot on desktops; ON on untrusted Wi-Fi for mobiles.
Split tunneling: optional. Exclude UK banking/work apps if they dislike VPNs.
Protocol auto-fallback: allow the app to retry (WG → OpenVPN TCP/443).

If your provider offers threat blocking/CleanWeb, it can reduce ad/trackers — handy on TVs.

Streaming tweaks (Netflix UK, BBC iPlayer)

Connect to a low-load UK server. If proxy/unblocker message appears — switch UK city.
Relaunch the app after each change. On TVs, clear app data if it clings to old region.
If Wi-Fi is congested, use Ethernet for TV/console; less jitter → fewer buffers.
On restrictive networks try OpenVPN TCP/443. Details: Netflix guide, iPlayer guide.

Speed optimisation (UK)

Protocol: WireGuard first. If packet loss → try OpenVPN TCP/443.
Server distance: pick closest UK city; avoid overloaded nodes.
Ethernet > Wi-Fi for 4K streaming and gaming.
MTU: for WG try 1420–1450 if you see fragmentation (advanced).
Background apps: pause cloud syncs/torrents during streaming tests.

App-by-app quick setup

Windows 10/11

Protocol: WireGuard; fallback: OpenVPN TCP/443.
Enable kill switch and DNS leak protection.
Flush DNS if needed: open cmd → ipconfig /flushdns.

macOS

Use native app (WG/NordLynx). Avoid manual profiles unless required.
Flush DNS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
Test kill switch once; verify no traffic leaks.

iOS/iPadOS

Protocol: WG/NordLynx; roaming: IKEv2 is fine.
Disable iCloud Private Relay while testing leaks.
Force-quit streaming apps after server/protocol changes.

Android

Enable Always-on VPN and Block connections without VPN.
Clear app data for stubborn streaming apps after changes.
If captive portal breaks things, reconnect after login; try TCP/443.

Browsers (WebRTC/DNS)

Chrome/Edge: privacy extension to limit WebRTC; optional DoH inside tunnel.
Firefox: lock down WebRTC or use an extension; DoH if supported by your VPN.
Safari: keep “Hide IP from trackers” on; ensure VPN owns DNS.

See our leak guide for full checks: IP/DNS/WebRTC leaks — UK.

Troubleshooting

Symptom	Likely cause	Fix
Proxy/unblocker message	Flagged IP / cached region	Rotate UK server → relaunch app → try TCP/443
Video buffers a lot	Wi-Fi jitter / server load	Use Ethernet, pick low-load UK server
Works on laptop, fails on TV	TV app cache	Clear app data/reinstall; consider router VPN
IP/DNS shows ISP	DNS leak	Turn on DNS leak protection; follow leak guide

Use a provider that supports these tweaks

Audited no-logs, robust apps, and fast UK servers make all the difference.
