Write an IR35 Compliant B2B Contract

We need assistance drafting an IR35 compliant B2B contract.

We are a recruitment agency engaging a consultant operating through their limited company to deliver services to one of our clients on an outside IR35 basis. The agreement will include a Statement of Work with defined deliverables, a rate of pay, and will operate on a time and materials basis. It must also include some protection to avoid the contractor from going to work directly for the end client once they have signed this for a period of time and other clauses to offer us as the agency and broker some kind of protection.

We already have an existing contract that we would like to adapt and update to ensure it is IR35 compliant, rather than creating something entirely new. We have attempted to revise it using tools such as Claude and ChatGPT, however the outputs have made the document unnecessarily complex, so we are looking for help simplifying and structuring it properly while ensuring it remains compliant.
