Largest web hosting providers in the United Kingdom 2025

The British web hosting market is among the largest and most developed in Europe. It is shaped by both internationally operating technology corporations and traditional providers with a local focus. Differences are not only in the size of the companies but also in the services offered and the customer segments targeted. Our overview of the leading web hosts in the UK shows which providers dominate the market and what factors determine their significance.

The UK's Position in the Global Hosting Market

The UK web hosting market is among the largest and most dynamic in Europe. According to a study for 2025, an revenue of approximately €13.38 billion is expected. With a projected annual growth rate of 14.38%, this volume is set to increase to around €26.28 billion by 2030. Notably, the average expenditure per employee, at €372.04, reflects the high importance of hosting and IT services in the United Kingdom.

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

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

According to the statistics from W3Techs, the UK ranks 8th worldwide in the distribution of websites by server location, with a share of 2.9%. This places the country between Brazil and Italy, while the USA and Germany hold the top positions with a clear lead. The dominant positions of the USA (1st place) and Germany (2nd place) emphasise their importance as central hosting locations with a high density of data centres and internationally operating providers. The British market is significant and growing, but many websites are hosted outside the country, whereas Germany and the USA, with their high data centre density and advantageous locations, have considerably higher shares of the global server distribution.

The Largest Web Hosts in the United Kingdom: Data Basis

Determining the largest web host in the UK is not entirely straightforward. Firstly, it must be defined based on which criteria the "size" of a web host is measured. Additionally, the choice of data sources is crucial, as they significantly influence the comparability and significance of the analysis.

To obtain the most well-founded results, various key figures and data sources are used for comparing UK web hosting companies. The following are utilised:

In second place is Fasthosts with a share of 4%. The third position goes to 20i with a share of 3%.

Conclusion of the analysis:

IONOS clearly positions 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 actual usage, securing a significant lead.

Following behind is Fasthosts, which, although somewhat lagging, maintains a consistent market presence and continues to be a key player in the competition.

Much smaller is 20i, which moves into the top 3 but still does not reach the reach and market penetration of the two leading providers.

At the same time, it becomes evident that companies such as Heart Internet or iomart are still present, but their visibility is considerably lower. For the UK hosting market, this means that the dynamics are heavily concentrated around the major brands. Smaller and specialised providers can primarily score points through niche solutions, unique services, or targeted audience approaches, while market leadership remains firmly with the big players.
