Frequently asked questions

What is the difference between a contractor and a freelancer?

A contractor typically works on longer-term engagements through a limited company or umbrella, often on-site with a single client at a time on defined deliverables. A freelancer usually juggles multiple shorter projects simultaneously, works remotely, and may operate as a sole trader. The tax treatment and employment status can differ depending on how HMRC views the specific working relationship in each case.

Which type of contractor earns the highest day rate?

Specialist IT contractors in areas such as cybersecurity, cloud architecture, and data engineering tend to command the highest day rates, often exceeding 700 to 1,000 pounds per day for senior roles. Finance and management consulting contractors also earn above-average rates, particularly for engagements based in London and the South East where demand is consistently strongest.

Do all types of contractors need a limited company?

No. Construction contractors often work as sole traders registered under the Construction Industry Scheme where tax is deducted at source. Some contractors prefer an umbrella company for simplicity, especially if their contracts fall inside IR35 and the tax advantages of a limited company are removed. A limited company is most tax-efficient for those earning above 50,000 pounds and working outside IR35.

What insurance do different types of contractors need?

IT and consulting contractors typically need professional indemnity insurance to cover errors in their work and advice. Construction contractors require public liability and often employers liability cover as well. All contractor types should consider cyber liability cover if they handle client data, and most end clients contractually require proof of at least one form of relevant insurance before the engagement begins.

Can a contractor work in more than one sector at the same time?

Yes. Many contractors take on concurrent engagements across different sectors and clients, provided there are no exclusivity clauses in their individual contracts restricting this. Running multiple contracts through a single limited company is straightforward from an accounting perspective, although you should ensure each engagement is assessed separately for IR35 status compliance.

How does IR35 affect different types of contractors?

IT and management consulting contractors face the highest IR35 scrutiny because their roles often closely resemble permanent employee positions within the client organisation. Construction contractors registered under CIS are generally outside the scope of IR35. Creative and media contractors sit in between, with HMRC focusing on practical factors like substitution rights, degree of client control, and mutuality of obligation.

What is a CIS contractor and how is it different from other contractors?

A CIS contractor works in the construction industry under the Construction Industry Scheme, where the main contractor deducts tax at source before making payment to the subcontractor. This differs from other contractor types who typically invoice their clients gross and manage their own tax payments independently through self-assessment or their limited company corporation tax return.
