⚡ UK Speed Tests

Tested on a 500 Mbps connection via BT FTTP in London. Proton VPN uses WireGuard by default, which delivers the best performance. Speeds are good for daily use but trail behind NordVPN and ExpressVPN for the fastest servers.

Server Location	Download	Upload	Ping
🇬🇧 London	385 Mbps	195 Mbps	8 ms
🇬🇧 Manchester	362 Mbps	178 Mbps	14 ms
🇳🇱 Amsterdam	340 Mbps	165 Mbps	18 ms
🇫🇷 Paris	328 Mbps	155 Mbps	22 ms
🇩🇪 Frankfurt	315 Mbps	148 Mbps	24 ms
🇺🇸 New York	245 Mbps	95 Mbps	82 ms
🇺🇸 Los Angeles	198 Mbps	78 Mbps	142 ms
🇯🇵 Tokyo	165 Mbps	55 Mbps	245 ms
🇦🇺 Sydney	142 Mbps	48 Mbps	280 ms
🔐 Secure Core (CH→UK)	185 Mbps	85 Mbps	35 ms

Average speed retention: 73%. UK servers are strong. Secure Core adds ~15ms latency but still very usable for streaming and browsing. Long-distance servers are average.

📺 Streaming Compatibility

Proton VPN added dedicated streaming-optimised servers in 2024 (Plus plan only). The free tier does NOT unblock streaming services. Results from March 2026:

Service	Status	Notes
Netflix UK	✅ Works	Plus servers, consistent
Netflix US	✅ Works	US streaming servers
BBC iPlayer	✅ Works	UK Plus servers required
Disney+	✅ Works	UK and US libraries
Amazon Prime	✅ Works	Reliable on Plus
ITV Hub / ITVX	✅ Works	UK servers
Channel 4	✅ Works	UK servers
NOW TV	⚠️ Partial	Works on some UK servers, not all
DAZN	❌ Blocked	Detected on all servers tested
Sky Go	❌ Blocked	VPN detection too strong
BT Sport	✅ Works	UK servers
Crunchyroll	✅ Works	US servers for full library

Verdict: Proton VPN handles most UK streaming services well on Plus plan. The free tier won't unblock anything — you'll need Plus for streaming. DAZN and Sky Go remain problematic across most VPNs.

🔐 Privacy & Security Deep-Dive

This is where Proton VPN truly shines. No other VPN comes close on transparency.

Swiss Jurisdiction

Switzerland isn't part of the EU, Five Eyes, Nine Eyes, or Fourteen Eyes intelligence alliances. Swiss privacy law requires a Swiss court order to compel any data — and even then, Proton has no connection logs to hand over. In 2019, a French government request was blocked by Swiss courts. Proton can't comply with foreign surveillance requests.

Fully Open Source

Every Proton VPN app (Windows, macOS, Linux, iOS, Android) is published on GitHub under GPLv3. Anyone can inspect the code. This is unique among major VPN providers — NordVPN, Surfshark, and ExpressVPN all have proprietary clients.

Independent Audits

Securitum (EU security firm) audited all Proton VPN apps and infrastructure in 2024. No critical vulnerabilities found. The no-logs policy has been validated by real-world legal proceedings — Proton has been ordered to hand over data multiple times and literally had nothing to give.

Secure Core

Proton's standout feature. Secure Core routes your traffic through hardened servers in Switzerland, Iceland, or Sweden before reaching the exit server. Even if an exit server is compromised, your real IP is protected. This adds ~15ms latency but provides meaningful protection against sophisticated adversaries.

NetShield Ad Blocker

DNS-level blocker that filters ads, trackers, and malware domains. Three levels: off, block malware only, or block malware + ads + trackers. Works across all devices without installing browser extensions.

Stealth Protocol

Proton's custom protocol designed to bypass VPN blocks in censored countries. Uses TLS over TCP to make VPN traffic look like regular HTTPS browsing. Effective in China, Russia, UAE, and Turkey. Alternative to OpenVPN's obfuscation.

Other Security Features

• Kill switch (permanent and app-level options)
• DNS leak protection (all DNS queries routed through Proton's servers)
• IPv6 leak protection
• Full-disk encryption on all servers
• Split tunnelling (Windows, Android, macOS)
• Tor over VPN (route through Tor network via Proton)
• Port forwarding (P2P optimised servers)

💷 Pricing (March 2026)

Proton VPN is mid-range. Cheaper than ExpressVPN, pricier than Surfshark. The free tier is a genuine differentiator.

Plan	Monthly	1-Year	2-Year
Free	£0	£0	£0
VPN Plus	£8.99/mo	£4.49/mo	£3.59/mo
Proton Unlimited	£10.99/mo	£7.99/mo	£6.49/mo

What Each Tier Gets You

Feature	Free	VPN Plus	Unlimited
Servers	200+ (5 countries)	6,500+ (112 countries)	6,500+ (112 countries)
Devices	1	10	10
Speed	Medium	Highest (10 Gbps)	Highest
Streaming	❌	✅	✅
Secure Core	❌	✅	✅
NetShield	❌	✅	✅
P2P / Port Forwarding	❌	✅	✅
Tor over VPN	❌	✅	✅
Proton Mail/Drive/Calendar	❌	❌	✅ (full suite)

Best value: VPN Plus 2-year at £3.59/mo. The Unlimited bundle is worth it if you'd also use ProtonMail, Proton Drive, and Proton Calendar — otherwise stick with VPN Plus.

🆓 The Free Tier — Is It Worth It?

Proton VPN's free plan is the best in the industry. Here's why:

• No data cap — unlimited bandwidth, no throttling after X GB
• No ads — completely ad-free, unlike Hotspot Shield or Windscribe
• No logs — same strict privacy policy as paid users
• Open source — same audited code as paid apps

The limitations are real though: 1 device, ~200 servers in 5 countries (US, NL, JP, US, RO), medium speeds (typically 50-100 Mbps), no streaming unlocking, no Secure Core, no P2P.

Who it's for: Anyone who needs basic privacy for browsing and doesn't want to pay. Students, travellers, or people who just want to encrypt public WiFi. It's the only free VPN we'd actually recommend.
