The London Stock Exchange (LSE) isn’t just a hub for banking, mining, and retail. It’s also home to a growing number of publicly listed UK software companies, catering to everything from enterprise accounting and cybersecurity to AI services and digital transformation. Let’s explore these companies, spanning large-cap stalwarts to rising mid-cap players.
Major Software Firms on the LSE
1. The Sage Group plc (FTSE 100)
A household name, Sage is the nation’s premier provider of enterprise accounting, payroll, HR, and CRM software—tailored mainly to small and medium-sized businesses. Founded in Newcastle in 1981 and listed in 1989, it’s one of the oldest tech names on the exchange.
Sage operates on a SaaS subscription model and boasts high recurring revenues—79% subscription penetration, 21% operating margins, and a 116% cash conversion rate. Their robust financials recently enabled a £400 million share buyback and dividend hike after a 43% leap in annual operating profit.
2. Micro Focus International plc (FTSE 100)
An enterprise software and services provider, Micro Focus offers tools for areas like IT operations, application delivery, and information management. Though once one of the UK’s top tech firms, its performance has fluctuated, especially post its acquisition by HPE in 2017, which triggered integration challenges.
3. Wise plc (LSE: WISE)
Wise (formerly TransferWise) is a fintech unicorn offering global multi-currency accounts and smart payment APIs. It’s not a pure software play but includes digital banking and payment infrastructure, making it a standout technology listing in London with a market cap of around £9.8 billion.
Noteworthy Mid-Cap Software and Tech-Service Firms
4. Kainos Group plc (FTSE 250)
Based in Belfast, Kainos delivers digital transformation platforms, Workday integration, AI, and automation solutions, serving both public and private sectors. It floated on the main market in 2015 and reported revenue of £382 million in 2024.

A leading reseller of software, Bytes is headquartered in Surrey. It sells IT and software solutions to businesses and floated in December 2020. In 2024, the company reported revenue of £207 million and net income of £47 million.

Specializing in transport tech, Tracsis offers software for rail, traffic, and transportation analysis. Listed on AIM since 2007 and headquartered in Leeds, it represents a niche yet valuable segment of UK software listings.
