Largest web hosting providers in the UK 2025

The position of the United Kingdom in the global hosting market

The British web hosting market is among the largest and most dynamic in Europe. According to a study for 2025, revenue of around €13.38 billion is expected. With a projected annual growth rate of 14.38%, this volume is forecast to rise to about €26.28 billion by 2030. Particularly notable are the average expenditures per employee, at €372.04, which reflect the high importance of hosting and IT services in the United Kingdom.

In a global context, the United Kingdom is clearly ahead of the smaller Central European markets: Germany is expected to generate around €10 billion in 2025, Switzerland about €2.25 billion and Austria around €1 billion. Nevertheless, the British market remains well behind the United States, which, with an expected revenue of €67.16 billion, plays a dominant role and accounts for the largest share of the global market.

Overall, with a market volume of €13.38 billion, the United Kingdom ranks among the leading hosting nations. The high level of competition, together with strong demand for secure and high-performance IT services, makes the market a central stage in Europe not only for international hyperscalers but also for locally established providers.

According to the W3Techs statistic, the United Kingdom ranks 8th worldwide for the geographic distribution of websites by server location, with a share of 2.9%. The country sits between Brazil and Italy, while the USA and Germany hold the top positions by a considerable margin. The leading positions of the USA (first place) and Germany (second place) underline their importance as central hosting locations with a high density of data centres and internationally operating providers. The UK market is significant and growing, yet many websites are hosted outside the country, whereas Germany and the USA, due to their high data-centre density and locational advantages, account for substantially larger shares of the global server distribution.

The largest web hosts in the United Kingdom: Data basis

Determining the largest web host in the United Kingdom is not straightforward. First, it is necessary to define by which criteria the “size” of a web host is measured. In addition, the selection of data sources is crucial, as it significantly affects the comparability and meaningfulness of the analysis.

To obtain the most well-founded result possible, various metrics and data sources are used to compare British web hosting companies. The following are employed:

Data on the usage distribution of web hosts in the United Kingdom from builtwith.com

The data on the usage distribution of web hosts in the United Kingdom determined by builtwith.com provide information on which web hosting providers are used by which websites.

builtwith.com gathers its data using a wide-ranging crawling procedure that fully captures both country-specific domains (ccTLDs) and generic domains (gTLDs). By analysing over 16.4 billion websites, it is possible not only to obtain detailed information about the technical infrastructure used, but also to derive precise statements about usage and market distribution across different regions. The results are processed at short intervals and published on the trends.builtwith.com platform every few days.

This shows that the hosting market in the UK is dominated primarily by the large hyperscalers such as Amazon AWS and Google Cloud. Other international providers such as Cloudflare, Squarespace and GoDaddy also appear in the statistics. With respect to UK-based web hosts, IONOS leads the usage distribution with 13%. In second place is Fasthosts with a share of 4%. Third place, with a share of 3%, goes to the provider 20i.

Data on search interest for web hosts in the United Kingdom on trends.google.com

The data on search interest for web hosts in the United Kingdom, obtained from trends.google.com, indicate which web hosting providers are most frequently searched for on Google.

The trends.google.com service uses information generated via its own search engine for its data collection. Every search query entered into Google is recorded and, together with general user behaviour, fed into the algorithms. This not only leads to continual improvements of search results but also produces extensive datasets on users' interests and behaviour patterns. These data are continuously processed and published on the trends.google.com platform in regularly updated form.

The analysis clearly shows: IONOS is by far in first place in search interest. Behind it, Fasthosts is in second place. 20i occupies third place by a clear margin, while Heart Internet is in fourth and iomart in fifth.

The largest web hosts in the United Kingdom: Analysis

We will now proceed to the analysis, referencing the different data sources.

When considering the largest web hosting providers in the United Kingdom, a largely consistent overall picture emerges. Both the analysis of usage distribution and of search interest show similar tendencies and confirm the leading role of a few providers. This correlation demonstrates that the main players in the UK hosting market emerge clearly across different measurement methods:

The largest web hosts in the United Kingdom are IONOS, Fasthosts and 20i.

Conclusion of the analysis:

IONOS clearly asserts itself as the dominant provider in the UK web hosting market and has further expanded its leading position over recent years. The company has gained both in search interest and in actual usage, securing a significant lead.

Following behind is Fasthosts, which appears somewhat trailing but maintains a consistent market presence and therefore remains an established competitor.

20i is positioned noticeably smaller; although it reaches the top 3, it does not match the reach and market penetration of the two leading providers.

At the same time, companies such as Heart Internet or iomart remain present, but their visibility is significantly lower. For the UK hosting market, this means dynamics are strongly concentrated around the major brands. Smaller and specialised providers can compete mainly through niche solutions, unique services or targeted audience approaches, while market leadership clearly remains with the large players.
