Statutory Standards and Frequently Asked Questions
Chapter 10 of ITEPA is the reason this board is filtered. For medium and large private-sector clients, the hirer must issue an SDS covering this contractor assignment in London. Inside IR35 means employment-like tax treatment: PAYE, employee NI, and usually an umbrella or client payroll. An outside SDS keeps PSC invoicing, with salary and dividend decisions inside the company. Fixed-term PAYE is a different employment wrapper and should not be blurred with outside IR35. A job advert’s IR35 badge is not a substitute for the SDS or for how the assignment actually runs in London. If the SDS is missing or disputed, use the client’s disagreement process before you start.
What is the contracting market like in London?
London dominates the UK contractor market by volume, depth, and rate levels. The capital concentrates the headquarters and major offices of most FTSE 100 companies, the largest global banks, the Big Four professional services firms, and the central government departments that collectively generate the majority of UK contract demand. Every contracting discipline covered on this site has active demand in London, from niche specialisms like threat intelligence and LLM engineering through to high-volume disciplines like project management and business analysis. The sheer density of employers means contractors in London typically have more choice of engagement at any given time than anywhere else in the UK. Day rates carry a premium of 15 to 25 per cent over the national average across most disciplines, reflecting both the concentration of complex, high-value programmes and the cost of operating in the capital.
What does Inside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.
Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
On QualityContracts.co.uk, approximately 49% of roles with a stated IR35 status are classified as inside IR35, making it the most common arrangement across the contract market. The proportion varies by sector and role type. Each listing on this page displays its IR35 status where provided by the hiring organisation.
How much do contractors usually earn in London when working Inside IR35?
Contract rates in London for inside IR35 engagements vary by discipline and seniority. Inside IR35 rates are typically 15% to 30% higher than equivalent outside IR35 roles to account for tax and national insurance deducted at source by the fee-payer.
