5 clauses missing from most UK freelance contracts

~6 min read · UK-jurisdiction · template content, not legal advice

Most UK freelance contracts I see are copy-pasted from somewhere US-shaped: California governing law, generic IP assignment, no Late Payment Act, no IR35 framing, no UK-statute citations. They mostly hold up for the easy work. They fall apart at exactly the moments contracts are meant to do their job: an unpaid invoice rolls past sixty days; a client wants to scope-creep without re-signing; HMRC takes a look at how you actually worked; the relationship sours and someone wants out fast.

Here are the five I see missing most often, with the statutory anchor and drop-in language for each. I wrote this for myself first; the pack at the end is the full version.

1.Statutory interest under the Late Payment Act

Why most templates miss it. Generic templates write "interest at 2% per month" and call it a day. Compounded, 2% per month is roughly 27% APR, which looks like a higher rate than the statute provides. It isn't always.

The Late Payment of Commercial Debts (Interest) Act 1998 gives you a statutory right to interest at 8% above the Bank of England base rate, currently 11.75% per annum (base 3.75% set 18 December 2025, fixed for debts becoming late between 1 January and 30 June 2026 under Art. 4 of SI 2002/1675). On top of that, s.5A gives you fixed compensation per invoice, automatically: £40 for invoices under £1,000; £70 for £1,000 to less than £10,000; £100 for £10,000 or more. You collect those without negotiating. A "2% per month" contractual clause doesn't get you that, and worse, it's vulnerable to being struck out as an unenforceable penalty under Cavendish Square v Makdessi [2015] UKSC 67. If the contractual rate falls, you may also lose the statutory bundle: the Act lets parties displace statutory interest by agreement (s.8), and a poorly drafted contract can do that by accident.

Primary: LPCD(I)A 1998 ss.5A, 6, 8; SI 2002/1675 Art. 4; Cavendish Square v Makdessi [2015] UKSC 67.

2.IR35 / off-payroll status documentation

Why most templates miss it. Most templates have no IR35 framing at all. The ones that do tend to overstate what a written representation can achieve.

The Client makes the determination (the Status Determination Statement, ITEPA 2003 s.61NA) when the engagement is in scope of the off-payroll rules. The freelancer's own representation does not override HMRC: working practice trumps written terms after Autoclenz Ltd v Belcher [2011] UKSC 41. What the freelancer's written representation gives you is narrower and still worth having. It documents your position at the point of signing, which is evidential ground if a status enquiry lands later. And if the Client's SDS later misclassifies the engagement and HMRC pursues you for the tax, your contractual representation creates a civil indemnity route back to the Client.

Primary: ITEPA 2003 s.61NA; Autoclenz Ltd v Belcher [2011] UKSC 41; HMRC v Atholl House Productions Ltd [2022] EWCA Civ 501.

3.Scope-creep deemed-acceptance clause (signed at inception)

Why most templates miss it. "Changes in writing" is too vague to operate as a clean default. The deemed-acceptance pattern is sharper, but it only works if it lives in the original signed contract.

Silence is not acceptance in UK contract law (Felthouse v Bindley (1862) EWHC CP J35), which means you can't bolt a 48-hour-deemed-accepted scope-creep mechanism onto a job after the fact. It has to be in the signed contract from the start. When it is, it gives you a clean automatic billing trigger for out-of-scope work and a paper trail that doesn't depend on chasing the client for written consent.

Primary: Felthouse v Bindley (1862) EWHC CP J35 (silence not acceptance).

4.IP assignment with a Background IP carve-out

Why most templates miss it. Blanket "all IP transfers to Client" clauses are common. Depending on how the deliverable is defined, those can be read to sweep in your prior libraries, internal tooling, and reusable components that you built before the engagement and embedded in the work.

CDPA 1988 s.90 requires assignments of existing copyright to be in writing signed by the assignor; s.91 covers future copyright. Courts read ambiguous assignment language against the assignor (contra proferentem), which gives you some protection. But the cleaner play is to define what you are and aren't assigning explicitly. Carve out Background IP (anything you brought to the engagement) and grant the Client a perpetual non-exclusive licence for the embedded use. They get to use what you delivered; you keep your tooling.

Primary: CDPA 1988 ss.90, 91.

5.Termination for non-payment with a defined cure window

Why most templates miss it. The default termination clause in most US-derived templates is 30 days' written notice, which is entirely client-favourable. The temptation is to flip it to "immediate on overdue", but that's hard to enforce and likely to be argued down by a court considering proportionality.

The right structure is a short defined cure period, fourteen days beyond the due date is the version I use, after which the freelancer can suspend work or terminate. UK B2B contracts can validly include this kind of termination right under UCTA 1977 reasonableness principles, provided the breach is material and the cure window is proportionate. Pair it with the IP assignment in clause 4: if termination fires, no IP transfers because no cleared funds have arrived.

Primary: Unfair Contract Terms Act 1977 s.3 (reasonableness in standard-form B2B); general contract-law principle of material-breach termination.

Why I built the pack

I kept hitting the same five gaps in my own contracts and I was tired of patching them inconsistently. The pack is eight templates that fit together (Master Services Agreement, SOW, NDA, IR35 appendix, IP assignment, payment terms, termination, scope-creep library), with the clauses above wired in throughout. Statute citations inline. UK-jurisdiction. Each template is a starting point, not legal advice; for engagements over £10,000, a solicitor pass is cheap insurance.

Template content, not legal advice. Status disputes can involve significant tax, NICs, and interest; for any engagement over £10,000, instruct a solicitor or chartered tax adviser. The drop-in language above is structurally accurate as of May 2026; statutory rates and thresholds are reviewed every six months (LPCD interest rate) or at HM Treasury's discretion (Companies Act small-company thresholds). Re-check before signing high-value work.
