Environmental Statement

Bytemark plans for the long-term, our approach to our environmental impact is no exception.

Our use of energy is our single most notable impact on the environment.
By pursuing lower long-term energy costs, we naturally make business decisions that reduce our environmental impact.

A practical, business-led approach to sustainability

Here are some of the specific steps we've taken to reduce our impact on the environment:

Cost Icon

Considering the cost of short-term savings

We select premium, lower-powered options that reduce costs over the long-term instead of choosing the short-term savings of cheaper, less efficient components.

Team Icon

Carefully considering customer needs

Not every customer needs the power of a dedicated server. After understanding your needs, we’ll happily offer a cheaper, more energy-efficient virtual server if appropriate. We don’t bulk out sales targets with expensive, overpowered servers.

Taking advantage of our Yorkshire surroundings

Our custom-built data centre “YO26” was designed to be as energy efficient as possible. We utilise fresh Yorkshire air rather than power-hungry air conditioning. When the external temperature is less than 21.5 C — 90% hours in the year! — the data centre can be cooled without the use of air conditioning compressors.

Awards & Recognition

We're proud that our achievements in reducing our environmental impact have been recognised:

Key Environmental Statistics

Our UPS units operate at 94% efficiency

The Uninterruptable Power Supply (UPS) units provide power to our servers continuously in the event of a power outage or brownout.

YO26 operates with an extremely low PUE

PUE (power usage effectiveness) measures data centre's energy efficiency. Scores range from 1.0 - 4.0. Our York data centre operates with a PUE of 1.2 or less, which is classed as very efficient.

All servers since 2014 have been built with Platinum-level power supplies

This is part of the 80plus scheme, which requires power supplies to be at least 80% efficient at up to 100% rated load.


All power consumption is monitored in real-time and logged, so we can track usage over time and continually find ways to improve.
