North West vs London Colocation: How UK Businesses Can Cut Data Centre Costs Without Compromise

The Rising Cost of London Colocation

For years, London has dominated the UK data centre landscape, offering unmatched connectivity, financial sector proximity, and a dense ecosystem of cloud on-ramps and network carriers. However, that dominance comes at a steep price. Power costs, real estate premiums, and sustained demand from hyperscale operators have driven London colocation rates to some of the highest in Europe, putting pressure on IT budgets across every sector.

According to recent market analysis, average colocation costs in London can run between 30 and 50 percent higher than equivalent facilities in regional UK cities. For businesses running dense compute workloads or requiring significant raised-floor space, that gap translates into tens or even hundreds of thousands of pounds in annual expenditure. As a result, infrastructure decision-makers are increasingly asking a critical question: is a London postcode still worth the premium?

Why the North West Is Emerging as a Serious Alternative

Manchester has firmly established itself as the UK's second digital city, with a thriving data centre market that has attracted major operators including Kao Data, UKCloud, and a growing number of carrier-neutral colocation providers. The city benefits from excellent fibre infrastructure, direct connectivity to the London Internet Exchange (LINX) via dark fibre routes, and strong links to transatlantic cable landing stations via Leeds and beyond.

Beyond Manchester, the broader North West region including Salford, Warrington, and Liverpool offers purpose-built data centre facilities with modern power infrastructure, strong renewable energy access, and significant room for expansion. Power Usage Effectiveness (PUE) ratings at newer North West facilities frequently match or exceed those found in older London stock, meaning operational efficiency is no longer a trade-off for choosing a regional location.

Breaking Down the Cost Difference

When evaluating colocation UK options, the cost comparison between London and the North West typically comes down to three core factors: power pricing, space rates, and connectivity costs.

• Power pricing: North West facilities often benefit from lower grid connection costs and greater access to renewable energy contracts, reducing overall power spend by 15 to 25 percent compared to Central London equivalents.
• Space rates: Rack and cage pricing in Manchester and surrounding areas can be 25 to 40 percent lower per unit than comparable London data centre facilities, particularly for deployments requiring multiple racks or private suites.
• Connectivity costs: While London benefits from the highest density of network providers, North West carriers and data centres have invested heavily in recent years, meaning competitive pricing on 10G and 100G circuits is now readily achievable.

For a mid-sized enterprise running 20 to 50 racks, the combined savings from relocating or distributing workloads to a North West colocation facility could realistically reach 200,000 pounds or more annually.

What You Might Give Up and How to Mitigate It

Fairness demands acknowledging the genuine advantages London retains. The capital hosts the majority of UK financial trading infrastructure, the highest concentration of internet exchange points, and the deepest pool of cross-connect options with major cloud providers including AWS, Microsoft Azure, and Google Cloud. For latency-sensitive financial applications or workloads requiring sub-5ms response times to London-based clients, a full migration away from the capital may not be appropriate.

However, many businesses do not actually require London-level latency for the majority of their workloads. A hybrid colocation strategy, keeping mission-critical or latency-sensitive systems in a London facility while migrating bulk storage, backup, disaster recovery, and development environments to the North West, can deliver substantial savings without any meaningful performance trade-off. This approach is increasingly common among data centres in the UK serving enterprise clients.

Key Questions to Ask Before Choosing a Region

Before committing to a North West colocation provider, infrastructure decision-makers should work through a structured evaluation process. The following questions will help frame the decision:

• What are the actual latency requirements for each application or workload in scope?
• Does your business have staff, customers, or partners concentrated in the North of England?
• What are your power density requirements, and does the candidate facility support future growth?
• Is carrier diversity and resilience available at the target site?
• What is the provider's track record on uptime, and are Tier III or equivalent standards certified?

The Bigger Picture for UK Data Centre Strategy

The conversation around North West vs London colocation reflects a broader maturation of the UK data centre market. Regional data centre facilities are no longer seen as a compromise option but as a legitimate, often superior choice for businesses prioritising efficiency, sustainability, and long-term cost control. UK data centres outside London now account for a growing share of new capacity deployments, with the North West, Scotland, and the Midlands all attracting significant operator investment.

For IT managers and infrastructure leaders reviewing their colocation UK strategy in 2024 and beyond, the North West deserves serious consideration not just as a cost-saving measure, but as a strategically sound decision for building a resilient, scalable, and future-proof infrastructure estate.
