Service Agreement Template UK | B2B Services Contract
Without a properly drafted service agreement, UK consultants and their clients risk costly disputes over scope, payment terms, and intellectual property ownership. A robust B2B services contract clearly defines deliverables, timescales, and fees, protecting both parties if the engagement breaks down. For consultants operating outside IR35 under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003, a well-structured service agreement is essential evidence of genuine business-to-business trading. Payment terms should comply with the Late Payment of Commercial Debts Act 1998, entitling you to statutory interest on overdue invoices. Your agreement should also address data protection obligations under UK GDPR and the Data Protection Act 2018. Stop relying on informal email chains or borrowed templates — generate a legally sound UK service agreement tailored to your consulting engagement right now.

Scope of Services
This clause precisely defines the deliverables, timescales, and boundaries of the consultant's work, preventing costly scope creep disputes. In the context of IR35 under Chapter 10 of ITEPA 2003, a tightly drafted scope clause helps demonstrate that the consultant is engaged for a specific outcome rather than working as a disguised employee.
Payment Terms and Late Fees
This clause sets out invoice schedules, payment deadlines, and the consequences of non-payment, giving both parties clear financial expectations. Under the Late Payment of Commercial Debts Act 1998, B2B invoices automatically attract statutory interest at 8% above the Bank of England base rate if not paid within agreed terms, and this clause reinforces that entitlement.
Intellectual Property Assignment
This clause determines who owns the work product created during the engagement — a critical issue often overlooked in consulting arrangements. Without an explicit assignment clause, UK copyright law under the Copyright, Designs and Patents Act 1988 may vest ownership in the consultant as the creator, leaving the client with only a licence unless ownership is expressly transferred in writing.

Does a service agreement help me prove I'm outside IR35?
A well-drafted service agreement is one of the key pieces of evidence HMRC examines when assessing IR35 status under Chapter 10 of the Income Tax (Earnings and Pensions) Act 2003. Clauses demonstrating a right of substitution, project-based engagement, and lack of mutuality of obligation all support an outside-IR35 position. However, HMRC looks beyond the contract itself and will also consider the actual working practices in practice.
Can I charge interest if a client pays my invoice late?
Yes — under the Late Payment of Commercial Debts Act 1998, you are legally entitled to charge statutory interest at 8% above the Bank of England base rate on overdue B2B invoices. You can also claim fixed debt recovery costs ranging from £40 to £100 depending on the invoice value. Including a payment terms clause in your service agreement that references these statutory rights strengthens your position if you need to chase payment.
Who owns the work I create as a consultant under a service agreement?
Under the Copyright, Designs and Patents Act 1988, copyright in work created by a freelance consultant generally belongs to the consultant, not the client, unless the contract explicitly assigns ownership to the client. Unlike employees, whose work-for-hire automatically vests in the employer, independent contractors retain intellectual property rights by default. A clear IP assignment or licence clause in your service agreement is therefore essential to avoid ownership disputes after the engagement ends.
