Freelance Interior Designer Contract Template UK
Without a written agreement, freelance interior designers risk unpaid invoices, disputed ownership of mood boards and design concepts, and costly scope creep that erodes project profitability. A robust freelance interior designer contract establishes the boundaries of your engagement, protects intellectual property in bespoke design work, and ensures timely payment under the Late Payment of Commercial Debts Act 1998, which entitles you to statutory interest on overdue invoices. For designers operating through a limited company or as a sole trader, a well-drafted contract also helps demonstrate genuine self-employment status and supports compliance with IR35 legislation under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003. Whether you are redesigning a residential space or delivering a full commercial fit-out, the right contract protects both parties from day one.

Intellectual Property Ownership
This clause defines who owns the design concepts, drawings, mood boards, and specifications created during the project, with ownership typically remaining with the designer until full payment is received. Under the Copyright, Designs and Patents Act 1988, original design works are automatically protected, but without a written assignment clause the client may incorrectly assume they own all outputs from the outset.
Scope of Works
This clause precisely details the design services to be delivered, including any exclusions such as project management, contractor oversight, or procurement services, preventing costly scope creep disputes. Clearly defining deliverables protects the designer from being held liable for work never agreed upon and gives both parties a contractual benchmark if the project expands.
Payment Terms and Late Fees
This clause sets out the fee structure, milestone payment schedule, and the consequences of late payment, including the right to charge statutory interest at 8% above the Bank of England base rate under the Late Payment of Commercial Debts Act 1998. Including an express right to suspend work for non-payment gives the designer a practical commercial remedy without needing to terminate the entire agreement.

Do I need a written contract as a freelance interior designer in the UK?
While verbal contracts are technically legally binding in England and Wales, they are extremely difficult to enforce when disputes arise over scope, payment, or intellectual property. A written contract provides clear evidence of the agreed terms and is essential if you ever need to pursue an unpaid invoice through the courts or HMRC disputes your self-employed status under IR35 rules.
Who owns the design concepts and drawings I create for a client?
Under the Copyright, Designs and Patents Act 1988, copyright in original design drawings and creative works belongs to the creator by default, meaning you as the freelancer retain ownership unless you explicitly assign it in writing. Your contract should specify whether you are granting the client a licence to use the work or transferring full ownership, and whether that transfer is conditional on receipt of full payment.
Can I charge interest if a client pays my interior design invoice late?
Yes, the Late Payment of Commercial Debts Act 1998 entitles you to charge statutory interest at 8% above the Bank of England base rate on overdue invoices in business-to-business transactions, along with fixed debt recovery costs of between £40 and £100 depending on the invoice value. You do not need to include this right in your contract for it to apply, but explicitly referencing it acts as a deterrent and signals to clients that late payment carries real financial consequences.
