Why choose colocation from iomart?

From the smallest requirement to the largest, iomart offers a full spectrum of solutions. Each one of our UK and global data centres is totally secure, highly resilient and designed to cope with all computing demands.

Reduce costs

Colocation hosting saves you money on infrastructure operating costs. Colocation from iomart is based on a monthly fee depending on how much rack space, power and bandwidth you need. We offer per ‘U’ colocation in addition to full rack and managed colocation (for caged areas, custom racks and fit-outs). Investment in colocation also allows you to free up resources and staff for important business projects.

Improve performance

No business wants to be static in its outlook. It is essential that your hardware is optimised to cope with changing demand. Our skilled technical teams can help configure for high availability. They monitor your servers round-the-clock to ensure a stable and controlled operating environment 24/7/365. Dual independent power feeds and on-site generators ensure power redundancy.


Diverse fibre routes connect you to multiple Tier 1 carriers. Our UK data centres are also inter-connected via a high-speed 10 GB private fibre network, offering the lowest latency.


Day-to-day maintenance of your servers can be managed remotely by your IT team or via our remote hands service. Access to our data centres is available 24/7 for your security checked IT staff when required.


Our data centres take a multi-layered approach to security to keep your data safe. They are compliant with the latest security policies and audit guidelines and are managed and monitored all year round by iomart staff. This includes: 24/7 interior and perimeter video surveillance, alarm monitoring, biometric and ingress/egress key card access controls, automatic number-plate recognition and cabinets secured with tumbler or pin locks and more. You won’t find a better home for your equipment.

Colocation FAQs

How do I set up a colocation server?

If you are interested in rack space, a cabinet or a cage, please request a quote using our contact form and one of our representatives will be in touch to discuss your requirements.

How does colocation work?

You rent space for your server hardware in one of our data centres. We provide the physical environment, the power and cooling, the bandwidth and the IP address so you can deploy your server.

The space provided can be a rack or a cabinet or a private cage, depending on your requirements.

Security and resilience are provided for you in the form of 24/7 manned security, CCTV and biometric access plus our backup UPS batteries and generators to protect against outages.

How much does colocation cost?

This will depend on your requirements. A rack of servers is measured in rack units or U. The price of your colocation will depend on how many U or units you require.

How do you connect us to the internet?

There are diverse connections out of our data centres and, because we are carrier neutral, those connections can be made to multiple carriers and ISPs.

Will my services be secure in your data centres?

Our infrastructure is protected 24/7. There is on-site physical security and constant video monitoring, plus secure access management to our facilities. Your servers are safe with us.

How do you meet data sovereignty requirements?

We own and operate a network of data centres across the UK so, if you are concerned about data sovereignty, we have that covered.

Our data centres in the UK are located in or near to the busiest metropolitan areas.

Take a look at our map or download our data centres brochure to find out more about our UK and international reach.

How do you ensure we have the required connectivity?

Our data centres connect with multiple Tier 1 carriers via a 10Gb network to provide internet connectivity and ensure your business is fully connected.

Who uses colocation services?

There are numerous reasons for a business to choose to move its servers out of its on premise data centre. The main three are around cost, connectivity and security.

It is costly to build and maintain your own data centre. By outsourcing to a reputable company like iomart, that owns and operates the infrastructure, you will drastically reduce long term, capital spend and move to a more manageable and predictable rental model.

Colocation offers the opportunity to connect with many more internet carriers.

It’s more than likely that security is not your business’ number one priority. It is for your colocation provider. At iomart we take security very seriously and protect and monitor your services 24/7.

What are the benefits of colocation v IaaS?

Colocation, which can also be referred to as Data Centre as a Service (DCaaS), is where you use a third party company like iomart, to provide your business with the physical environment, the power and the cooling to run your server hardware and networking equipment on. You retain control over your resource.

In comparison, Infrastructure as a Service (IaaS), also provides the servers and the storage you require to run your applications and workloads.

Whereas DCaaS is about leveraging the benefits of using the provider’s physical facility, i.e. the data centre, IaaS provides that plus the computing resources on top. With the focus on running workloads rather than just the hardware, IaaS can lead to a loss of control that some businesses might not be ready for. However if and when you are ready for IaaS then iomart can provide this too.
