Frequently asked questions

How much does a rack (colocation) cost in Slough?

a full rack is priced on electrical power (kVA), IP transit and cross-connects. Compare the 26 data centers in Slough to get a costed quote.

What is the difference between housing and colocation?

None: “housing” and “colocation” mean the same thing — hosting your own servers in a third-party data center, as opposed to renting a dedicated server or public cloud.

Which data centers in Slough are ISO 27001 certified?

6 of the 26 data centers listed in Slough declare ISO 27001. Filter by certification (ISO 27001, HDS, PCI-DSS) in the comparator to keep only compliant sites.

What does a rack in Slough really cost?

Beyond listed prices, here is the computed cost of a standard 5 kW rack in Slough, from our open market model (published method, version 2026.07-v1):

ItemEstimate
5 kW rack, per month€1,321 – €1,625
Cost per kW per month€232 – €284
Over 3 years (36 months)€47,556 – €58,500

Amounts are in euros: the model is computed in EUR, including for markets outside the euro area. We do not show a GBP conversion until a dated, sourced rate backs it.

What this covers: local industrial energy tariff, site efficiency (PUE), retail colocation margin and local market tightness. What it does not: IP transit, cross-connects, setup fees and PDUs — priced site by site in the comparator.

An estimate, not an offer. It is a model, with an open method and a version — not a contractual rate. A quote prices your actual configuration. Think the model is wrong? The method is published: tell us where.

What Slough allows

Slough has 26 data centers, operated by Equinix, Inc., CyrusOne Inc., Iron Mountain Data Centers, NTT DATA's Global Data Centers division. Declared design level: Tier III. That level describes the building's redundancy, not a contractual availability commitment: only the contract carries one. Available formats range from 1 baie to 1 baie: you can start small here, without renting a whole rack.

Connectivity from Slough

163 networks are listed at the sites in Slough according to public interconnection registries. That number drives your negotiating power: every carrier inside the building is one more quote, with no civil works. 8 Internet exchange points are reachable from these sites, which cuts latency to the large content networks and the cost of transit. The large networks reachable directly from these sites, without buying transit, are Alibaba Cloud, Amazon Web Services, DigitalOcean, Google, Hetzner, IBM Cloud, Microsoft Azure, Oracle Cloud and 9 more: they are present at the exchange points where 5 of the 26 sites in the city are points of presence. Reaching your cloud over an exchange point rather than the public Internet changes latency, and above all the price of data egress.

Compliance and sovereignty

Declared certifications: ISO 22301, ISO 27001, ISO 50001, PCI DSS, SOC 2. A certification is verified site by site and carries an expiry date: ask for the certificate, not the logo. Note: part of the operation falls under a US-jurisdiction company, hence under the CLOUD Act. Hosting in Europe is not enough to escape it: what counts is the provider's nationality, not the building's address.

The electricity behind Slough

A city has no electricity of its own: the sites in Slough are connected to the national grid, itself interconnected with its neighbours. What is measured, and what decides, is therefore the country's generation mix. No single source dominates it: the largest, natural gas, supplies only 31.1% (2025). The detail: natural gas 31.1%, wind 29.4%, bioenergy 14.1%, nuclear 12.4%, solar 6.6%, oil (fuel oil, diesel) 4.4%. Fossil fuels (coal, gas, oil) account for 35.6% of it. A kilowatt-hour there weighs 217 g of CO2, i.e. 2.1 times less than the world average (458 g), 2025 figure. Concretely: a 3 kVA rack, in a site with a PUE of 1.5, draws 35,478 kWh a year and therefore emits 7.7 tonnes of CO2 a year here. The same rack, same hardware, same PUE, would emit 16 tonnes on a world-average grid. The building has nothing to do with it: the country does.

What the ground has done under Slough

No earthquake of magnitude 5 or above has been recorded within 200 km of Slough since 1970, according to the US Geological Survey's global catalog. This record covers 56 years, which is short on a seismic timescale: no recorded earthquake does not mean no hazard. It does not replace the statutory zoning, which alone binds construction.

What Slough does not allow

No rate is published by the operators in this city: pricing is on request, and we do not estimate it on their behalf.

Other cities with data centers near Slough

The nearest site outside Slough is 6 km away, in Maidenhead (2 sites). Short distances matter: they drive the cost of a link between two buildings, and whether a backup site is workable.
