IPSE

IPSE stands for the Association of Independent Professionals and the Self-Employed. It's the UK's largest membership organisation specifically for freelancers, contractors, and the solo self-employed.

It was originally founded in 1999 as the Professional Contractors Group (PCG) — a protest organisation set up in direct response to the introduction of IR35 tax legislation. In 2014, it rebranded as IPSE to better reflect a broader membership base, as self-employment in the UK had grown well beyond the IT contracting sector it originally served.

Today, IPSE operates across three main areas.

Lobbying and policy. IPSE represents the self-employed in conversations with government. That means responding to consultations, submitting evidence to parliamentary committees, and pushing back on legislation considered harmful to the sector. IR35 has remained a central focus, but their policy work covers a wider range of issues including late payment, access to finance, and pension provision for the self-employed.

Research. IPSE publishes regular research on the shape and conditions of the sector. Their annual Self-Employed Landscape report tracks things like the economic contribution of the solo self-employed, demographic changes, and freelancer confidence. They also publish more focused reports, including an annual IR35 Spotlight tracking the ongoing impact of off-payroll working rules on contractors. This research is publicly available and widely cited.

Membership. IPSE offers several membership tiers covering freelancers, limited company directors, umbrella workers, and those just starting out. Benefits vary by tier but typically include access to a tax and legal helpline, contract templates and guides, co-working access, and insurance cover for things like tax investigations, illness, injury, and jury service.

IPSE has historically had a strong following among contractors working through limited companies, particularly in technical and professional services. But their scope has expanded over time to include sole traders, people with side hustles, and those earlier in their self-employed journey.

It's worth knowing about IPSE whether or not you become a member. The policy issues they campaign on affect everyone working independently in the UK. The research they publish is some of the most reliable sector-level data available. And if you're a limited company director working on longer contracts, the insurance and legal cover within membership can be worth the cost on its own.
