Tier 3 data center accounted for majority share in terms of volume in 2023, it will continue its dominance during forecast period

  • Tier 3 data centers are the most preferred due to features such as onsite assistance, power, and cooling redundancy. The Tier 3 DC market was operating at 1540.98 MW in 2022. The expected capacity during the forecast period is expected to grow from 1813.19 MW in 2023 to 3369.24 MW in 2029 at a CAGR of 10.88%. These data centers are 'concurrently maintainable' with redundant components as a key differentiator.
  • SMBs generally prefer to use at least a tier III-rated system for the far superior redundancy protections offered. In the United Kingdom, SMEs account for 99.9% of the business population. At the start of 2022, there were estimated to be 5.5 million businesses in the UK private sector. Major adoption of tier 3 facilities is reflected in BFSI, telecom, and media and entertainment users are majorly adopting wholesale and hyperscale colocation. As of 2022, there are around 148 Tier 3 data centers in the country, and around 28 upcoming data centers are under construction with Tier 3 standards.
  • Tier 4 is the next most preferred data centers by large enterprises due to their fault-tolerant functionality, lower downtime, and 99.99% uptime. It is expected that the market will showcase potential growth during the forecast period with the adoption of hyperscale colocation by major end users in the cloud and telecom sectors. The UK government's G-Cloud program is changing the way public sector organizations purchase information and communications technology. In 2022, the country had two Tier 4 data centers owned by Exascale Ltd and ServerMania.
  • The Tier 1&2 data centers are the least preferred due to their single path for power and cooling and providing expected uptime of 99.671% (28.8 hours of downtime annually) when compared to Tier 3 and Tier 4 facilities.

United Kingdom Data Center Market Trends

Increase smartphone penetration rate, emergence of 4G and 5G services to boost market growth

  • The number of smartphone users in the country was 63.46 million in 2022 and is expected to witness a CAGR of 1.01% during the forecast period to reach a value of 68 million by 2029.
  • The smartphone penetration rate in the United Kingdom has increased each year, reaching an overall figure of 93% in 2022. Among the age group of 16-24, the smartphone ownership rate was 99% in 2022. The number of mobile internet users in the United Kingdom reached 62.3 million, a figure which is projected to increase by approximately 2.86 million and amount to over 65 million by 2026 with the emergence of 4G and 5G. Further, since the COVID-19 pandemic hit, people have increased their smartphone usage and spent more time on online gaming or media streaming platforms. As a result, in April 2020, the industry increased the spending limit on individual contactless card payments from GBP 30 to GBP 45 to help with online payments. Such a scenario has increased smartphone penetration and is currently following the same trend.
  • The growth of the user base positively boosted the market demand for data centers. The increasing rate has positively upheld its growth in the e-commerce, media and entertainment, and BFSI sectors, where a large chunk of data has been generated. Since smartphones necessitate real-time processing on having a large data chunk, they mostly require a data center for storage. During the historical period, when smartphone usage penetration increased from 72% in 2017 to more than 90% in 2022, the number of racks in the data center increased from around 215k in 2017 to 388k in 2022. This trend is further expected to be witnessed during the forecast period.

Phase out of 2G and 3G and adoption of 4G and 5G network and increase in use of mobile devices to drive market growth

  • The United Kingdom's first 5G network was activated in May 2019, and 4G was launched in October 2012. Since being commissioned, both networks have shown an increment in their data speed. 4G speed increased from 12 Mbps in 2012 to 36.40 Mbps in 2022. Similarly, 5G speed increased from 139.5 Mbps in 2019 to 160.15 Mbps in 2022. In May 2022, according to an industry survey, around 67% of respondents in the United Kingdom (UK) had a 4G service on their smartphone, while about 25% had a 5G service.
  • The UK will phase out 2G and 3G mobile services by 2033. The major strategy for all the operators is to turn off their 2G and 3G networks, allowing them to focus investments and spectrum resources on further improving the 4G customer experience while rolling out 5G. The UK government has outlined its intentions to invest in driving 5G and 6G development with the support of GBP 110 million (USD 135 million) worth of investment. Moreover, the switch-off date for 2G and 3G has been agreed upon with mobile-network operators Vodafone, EE, Virgin Media, O2, and Three.
  • The growth in speed and better overall connectivity is paving the way for other end-user industries. In 2021, users in the United Kingdom spent an average of four hours per day using their mobile devices. This was an increase of 0.3 hours up from 2020. The number of social media users in the United Kingdom at the start of 2022 was equivalent to 84.3% of the total population, and it increased by 4.6 million between 2021 and 2022. Overall, this will increase the mobile data speed, increasing the data traffic, which thereby requires data centers for storing and processing data.

Keyword Definition
Rack Unit Generally referred as U or RU, it is the unit of measurement for the server unit housed in the racks in the data center. 1U is equal to 1.75 inches.
Rack Density It defines the amount of power consumed by the equipment and server housed in a rack. It is measured in kilowatt (kW). This factor plays a critical role in data center design and, cooling and power planning.
IT Load Capacity The IT load capacity or installed capacity, refers to the amount of energy consumed by servers and network equipment placed in a rack installed. It is measured in megawatt (MW).
Absorption Rate It denotes how much of the data center capacity has been leased out. For instance, if a 100 MW DC has leased out 75 MW, then the absorption rate would be 75%. It is also referred to as utilization rate and leased-out capacity.
Raised Floor Space It is an elevated space built over the floor. This gap between the original floor and the elevated floor is used to accommodate wiring, cooling, and other data center equipment. This arrangement assists in having proper wiring and cooling infrastructure. It is measured in square feet/meter.
Computer Room Air Conditioner (CRAC) It is a device used to monitor and maintain the temperature, air circulation, and humidity inside the server room in the data center.
Aisle It is the open space between the rows of racks. This open space is critical for maintaining the optimal temperature (20-25 °C) in the server room. There are primarily two aisles inside the server room, a hot aisle and a cold aisle.
Cold Aisle It is the aisle wherein the front of the rack faces the aisle. Here, chilled air is directed into the aisle so that it can enter the front of the racks and maintain the temperature.
Hot Aisle It is the aisle where the back of the racks faces the aisle. Here, the heat dissipated from the equipment’s in the rack is directed to the outlet vent of the CRAC.
Critical Load It includes the servers and other computer equipment whose uptime is critical for data center operation.
Power Usage Effectiveness (PUE) It is a metric which defines the efficiency of a data center. It is calculated by: (𝑇𝑜𝑡𝑎𝑙 𝐷𝑎𝑡𝑎 𝐶𝑒𝑛𝑡𝑒𝑟 𝐸𝑛𝑒𝑟𝑔𝑦 𝐶𝑜𝑛𝑠𝑢𝑚𝑝𝑡𝑖𝑜𝑛)/(𝑇𝑜𝑡𝑎𝑙 𝐼𝑇 𝐸𝑞𝑢𝑖𝑝𝑚𝑒𝑛𝑡 𝐸𝑛𝑒𝑟𝑔𝑦 𝐶𝑜𝑛𝑠𝑢𝑚𝑝𝑡𝑖𝑜𝑛). Further, a data center with a PUE of 1.2-1.5 is considered highly efficient, whereas, a data center with a PUE >2 is considered highly inefficient.
Redundancy It is defined as a system design wherein additional component (UPS, generators, CRAC) is added so that in case of power outage, equipment failure, the IT equipment should not be affected.
Uninterruptible Power Supply (UPS) It is a device that is connected in series with the utility power supply, storing energy in batteries such that the supply from UPS is continuous to IT equipment even during utility power is snapped. The UPS primarily supports the IT equipment only.
Generators Just like UPS, generators are placed in the data center to ensure an uninterrupted power supply, avoiding downtime. Data center facilities have diesel generators and commonly, 48-hour diesel is stored in the facility to prevent disruption.
N It denotes the tools and equipment required for a data center to function at full load. Only "N" indicates that there is no backup to the equipment in the event of any failure.
N+1 Referred to as 'Need plus one', it denotes the additional equipment setup available to avoid downtime in case of failure. A data center is considered N+1 when there is one additional unit for every 4 components. For instance, if a data center has 4 UPS systems, then for to achieve N+1, an additional UPS system would be required.
2N It refers to fully redundant design wherein two independent power distribution system is deployed. Therefore, in the event of a complete failure of one distribution system, the other system will still supply power to the data center.
In-Row Cooling It is the cooling design system installed between racks in a row where it draws warm air from the hot aisle and supplies cool air to the cold aisle, thereby maintaining the temperature.
Tier 1 Tier classification determines the preparedness of a data center facility to sustain data center operation. A data center is classified as Tier 1 data center when it has a non-redundant (N) power component (UPS, generators), cooling components, and power distribution system (from utility power grids). The Tier 1 data center has an uptime of 99.67% and an annual downtime of <28.8 hours.
Tier 2 A data center is classified as Tier 2 data center when it has a redundant power and cooling components (N+1) and a single non-redundant distribution system. Redundant components include extra generators, UPS, chillers, heat rejection equipment, and fuel tanks. The Tier 2 data center has an uptime of 99.74% and an annual downtime of <22 hours.
Tier 3 A data center having redundant power and cooling components and multiple power distribution systems is referred to as a Tier 3 data center. The facility is resistant to planned (facility maintenance) and unplanned (power outage, cooling failure) disruption. The Tier 3 data center has an uptime of 99.98% and an annual downtime of <1.6 hours.
Tier 4 It is the most tolerant type of data center. A Tier 4 data center has multiple, independent redundant power and cooling components and multiple power distribution paths. All IT equipment are dual powered, making them fault tolerant in case of any disruption, thereby ensuring interrupted operation. The Tier 4 data center has an uptime of 99.74% and an annual downtime of <26.3 minutes.
Small Data Center Data center that has floor space area of ≤ 5,000 Sq. ft or the number of racks that can be installed is ≤ 200 is classified as a small data center.
Medium Data Center Data center which has floor space area between 5,001-20,000 Sq. ft, or the number of racks that can be installed is between 201-800, is classified as a medium data center.
Large Data Center Data center which has floor space area between 20,001-75,000 Sq. ft, or the number of racks that can be installed is between 801-3,000, is classified as a large data center.
Massive Data Center Data center which has floor space area between 75,001-225,000 Sq. ft, or the number of racks that can be installed is between 3001-9,000, is classified as a massive data center.
Mega Data Center Data center that has a floor space area of ≥ 225,001 Sq. ft or the number of racks that can be installed is ≥ 9001 is classified as a mega data center.
Retail Colocation It refers to those customers who have a capacity requirement of 250 kW or less. These services are majorly opted by small and medium enterprises (SMEs).
Wholesale Colocation It refers to those customers who have a capacity requirement between 250 kW to 4 MW. These services are majorly opted by medium to large enterprises.
Hyperscale Colocation It refers to those customers who have a capacity requirement greater than 4 MW. The hyperscale demand primarily originates from large-scale cloud players, IT companies, BFSI, and OTT players (like Netflix, Hulu, and HBO+).
Mobile Data Speed It is the mobile internet speed a user experiences via their smartphones. This speed is primarily dependent on the carrier technology being used in the smartphone. The carrier technologies available in the market are 2G, 3G, 4G, and 5G, where 2G provides the slowest speed while 5G is the fastest.
Fiber Connectivity Network It is a network of optical fiber cables deployed across the country, connecting rural and urban regions with high-speed internet connection. It is measured in kilometer (km).
Data Traffic per Smartphone It is a measure of average data consumption by a smartphone user in a month. It is measured in gigabyte (GB).
Broadband Data Speed It is the internet speed that is supplied over the fixed cable connection. Commonly, copper cable and optic fiber cable are used in both residential and commercial use. Here, optic cable fiber provides faster internet speed than copper cable.
Submarine Cable A submarine cable is a fiber optic cable laid down at two or more landing points. Through this cable, communication and internet connectivity between countries across the globe is established. These cables can transmit 100-200 terabits per second (Tbps) from one point to another.
Carbon Footprint It is the measure of carbon dioxide generated during the regular operation of a data center. Since, coal, and oil & gas are the primary source of power generation, consumption of this power contributes to carbon emissions.
