Colocation Services in Central London


In addition to being highly resilient and concurrently maintainable to the highest Tier III standards, Volta’s data centre provides a colocation centre of choice in the heart of London. Its Great Sutton Street facility is perfect for organisations who want to take advantage of all the benefits of colocation, while keeping their data within easy reach.

Why co-locate?

Whether your company is a start-up or a well-established global business, it relies on Big Data to grow and develop, using data analysis to gather crucial insights into consumer behaviour and to inform important strategy decisions. As your place of work and the hub of your communications, your office is not equipped to safely and securely store that critical infrastructure.

That’s why businesses of all sizes choose colocation, renting out purpose-built space for their data in the form of cabinets and racks (a rack is a standardised frame for mounting equipment and hardware). Colocation providers deliver high levels of security, with security guards and biometric access control available at all times.

Colocation providers also bring peace of mind, with data centres offering reliable backups and UPS devices to protect data against outages, including those caused by natural disaster, fire or flooding.


The advantages of colocation

Colocation services generally provide a range of business benefits. As inhouse server rooms are so complex and expensive to maintain, storing them in a dedicated facility means significant cost and time savings. Data centres are also built with enhanced security and compliance in mind. They allow for easy scalability, are manned by expert engineers 24/7, and offer levels of redundancy and uptime that an office server room simply cannot match.

Volta’s central London colocation spaces offer all this and are even pre-configured to your specific requirements ahead of moving in day to minimise set-up time and resource. If it’s colocation in London you’re looking for, whether you need individual racks or full cages with multiple racks, Volta Data Centres can house, secure, and maintain, your assets with ‘always on’ power and connectivity.


The importance of physical security

The IT hardware today’s businesses use is critical to their existence. If data is lost, connectivity or power fails for a significant period of time, or assets are seriously compromised, the damage to the brand can be irreparable.

At Volta Data Centres, we understand this. It’s one of the reasons our Great Sutton Street site was chosen, with its rugged build quality and comfortable distance from flood risk areas.

To further fortify your assets, we employ 24/7 manned security, use external and internal HD CCTV systems and optional biometric ID-only entry points, regularly update maintenance logs and testing schedules and deploy rigorous fire risk protocols.


The Volta space is different

Customers who entrust us with their critical IT assets are, of course, drawn to our multiple accreditations and certifications, transparent pricing, easy scalability options, heavy-duty security, 100% uptime, formidable resilience, state-of-the-art cooling systems, and green credentials, but our facility itself offers some very human benefits too.

Located as we are in central London, our facility is just seven minutes from Barbican Station, 10 minutes from Farringdon Station, 15 minutes from Old Street Station, and 16 minutes from Bank Station, meaning your infrastructure is within easy reach. If you’re driving to us, parking with free EV charging points as well.

Once inside, our customers have access to stylish meeting rooms, changing rooms with hot showers, a comfortable break-out lounge, and kitchen facilities. And, if you feel like a change of scenery, upon stepping out of our grounds, you will be met with an array of pubs, bars, and eateries.
