How to Draft a SaaS Terms in the UK
If you're building a SaaS product and selling to UK businesses or consumers, knowing how to draft a SaaS terms and conditions UK document is not optional — it's the legal foundation your product sits on. Your terms define what you're selling, what you're not responsible for, how data is handled, and what happens when things go wrong. Get it wrong and you're exposed to liability, GDPR breaches, and disputes with no clear resolution path. This guide walks through every section you need to include: from acceptable use and payment terms to liability caps, IP ownership, and termination rights. It's written for founders who don't have a legal team on retainer but still need something that holds up. We'll also be straight with you about when a template isn't enough and you need a solicitor to review what you've produced. UK law — including the Consumer Rights Act 2015, GDPR, and the Unfair Contract Terms Act 1977 — shapes what you can and cannot include. This guide respects that.

FAQ
Do I legally need terms and conditions for my SaaS product in the UK?
There's no single law that says you must have terms and conditions, but without them you have no contractual basis for your pricing, no liability protection, and no agreed process for disputes. In practice, operating a SaaS product without terms exposes you to significant legal and financial risk. If you process personal data — which almost every SaaS product does — you also have GDPR obligations that terms and a privacy policy help you meet.
Can I just copy terms from another SaaS company?
No. Copying another company's terms is copyright infringement, and their terms almost certainly don't reflect your product, your pricing model, or your liability position. US-based terms are particularly problematic — they reference US law, US consumer protections, and dispute resolution mechanisms that don't apply in the UK. You need terms that are specific to what you actually offer and compliant with UK law.
What's the difference between SaaS terms for B2B versus B2C customers?
If you sell to consumers, the Consumer Rights Act 2015 applies. This means certain terms — like blanket liability exclusions — are unenforceable, and consumers have statutory rights you cannot contract out of. B2B terms give you more flexibility, particularly around liability caps and limitation of consequential loss. If you sell to both, you either need separate terms or a single document that clearly distinguishes between the two customer types.
What should my liability cap be in SaaS terms?
For B2B SaaS, a common approach is to cap liability at the fees paid by the customer in the 12 months preceding the claim. This is a recognised commercial standard in the UK and is generally enforceable between businesses, provided it passes the reasonableness test under the Unfair Contract Terms Act 1977. For B2C, you cannot cap liability for death, personal injury, or fraud — and some other caps may be unenforceable. If your product handles sensitive data or financial decisions, get a solicitor to review your liability clauses.
Do my SaaS terms need to include GDPR clauses?
Yes, if you process personal data — which includes names, email addresses, and usage data. At minimum, your terms should reference your privacy policy and clarify whether you act as a data controller or processor. If you process data on behalf of your customers (common in B2B SaaS), you likely need a Data Processing Agreement as a separate document or an addendum to your terms. The ICO provides guidance on what this should cover.
When should I get a solicitor to review my SaaS terms instead of using a template?
Use a solicitor if you're entering enterprise contracts with large organisations, operating in a regulated sector (fintech, healthtech, legal tech), handling particularly sensitive personal data, or if a customer's legal team has redlined your terms. For early-stage products with standard subscription models and SME customers, a well-structured template reviewed carefully by you is a reasonable starting point — but treat it as a first draft, not a final answer.
