Based on several discussions in our Dedicated Server forum we have come to this conclusion that these are the top Dedicated server providers for United Kingdom (UK).
1. Ultahost
UltaHost offers robust dedicated server hosting services specifically designed for the UK market, with data centers strategically located in London to provide optimal performance for British businesses and their European customers.

Instant server setup with full root access, IPMI/KVM access, and fast NVMe SSD storage.
Unlimited bandwidth, strong security protections (DDoS, SSL, BitNinja, built-in firewalls), and high uptime (99.99%).
Managed hosting, including regular security patches, auto-healing, free migration, backups, and 24/7 expert support.
Variety of OS options, from Windows Server to multiple Linux distributions; additional features like caching (Varnish, Redis), CDN add-ons, staging environments, floating IPs, team collaboration tools, and a rich knowledge base.
2. SiteGround
SiteGround’s UK dedicated servers offer a compelling mix of performance, reliability, and advanced features deal for businesses prioritizing speed, uptime, and expert support via a Google Cloud-powered platform. If you’re ready to invest in premium hosting and can budget for potential renewal increases, it’s a strong choice. But if cost predictability or price sensitivity are concerns, you might consider comparing with other UK-focused bare-metal or VPS providers.
Key Features:
SiteGround now focuses on fully-managed Cloud Hosting that runs on Google Cloud and includes tons of extras – daily backups, free CDN, unique performance boosters, dedicated IP and more. This represents a strategic pivot from their previous dedicated server model.
Rather than traditional dedicated servers, SiteGround emphasizes their cloud-based approach with features like automatic scaling, built-in CDN, and advanced caching technologies. Their hosting is powered by superior technology and 24/7 support, with all plans equipped with easy website tools and advanced extras.
SiteGround’s current cloud hosting offerings may actually provide better performance, scalability, and reliability than traditional dedicated servers, especially for most business applications.

4. Atlantic.net
Atlantic.Net provides a robust, UK-based hosting solution with enterprise-level SLA guarantees, compliance certifications, and experienced support. Although their London infrastructure seems well-positioned for dedicated hosting, direct plan details (e.g., pricing, exact hardware specs) are not prominent—likely requiring contact with sales to get tailored options.
Key Features:
Atlantic.Net supports both Dedicated Hosts (physical servers) and Dedicated Instances (virtual machines on dedicated hardware), ideal for compliance-heavy workloads and eliminating noisy neighbor issues.
Their infrastructures come with strong SLA guarantees : 100% network uptime, 100% hardware uptime & 100% infrastructure uptime.

These servers deliver full CPU and RAM access, ideal for intensive tasks like complex MySQL queries, heavy PHP processing, or managing uncacheable site activity. They’re especially valuable during traffic surges—for example, one dedicated server handled over 1 million page views in just 6 hours, reducing page load times by more than 50%.
