SLA Review Checklist: What to Check Before You Sign

A service level agreement review checklist for UK businesses helps you catch the clauses that cost you money, time, and leverage before you commit. SLAs look straightforward until something goes wrong — then the gaps in uptime guarantees, remedies, and termination rights become very expensive problems. This guide gives you a practical, UK-specific checklist to work through before signing any SLA, whether you're a buyer locking in a software vendor or a supplier protecting your delivery commitments. We cover the must-have clauses, the red flags that signal a poorly drafted agreement, and the points where you should stop and get a solicitor involved. Atornee can read your SLA, flag the issues, and explain what they mean in plain English — so you go into any negotiation knowing exactly where you stand. This is not legal advice, but it is a solid starting point for any UK founder or operations lead who needs to move fast without getting caught out.

Why this matters

Most UK businesses sign SLAs without reading them properly. The document arrives, looks professional, and gets countersigned in a rush. Then the supplier misses a deadline, the software goes down, or you try to exit the contract — and you discover the remedies are capped at a month's fees, the uptime guarantee has seventeen carve-outs, and the termination clause locks you in for another year. The real pain here is not complexity, it is time pressure. You do not have hours to read dense legal text before a vendor call. You need to know quickly what matters, what is missing, and what is genuinely dangerous. That is the problem this page solves.

The Atornee approach

Atornee is not a generic AI that summarises documents. It is built specifically for UK business legal documents. Upload your SLA and Atornee will identify missing remedy clauses, flag uncapped liability exposure, highlight vague performance metrics, and explain termination conditions in plain English — mapped to UK contract law context. It does not replace a solicitor for high-value or complex deals, and it will tell you honestly when you need one. For straightforward SLA reviews where you need a fast, informed read before a negotiation, Atornee gives you that without the hourly rate.

What you get

A clause-by-clause breakdown of your SLA highlighting what is missing, vague, or one-sided
Plain English explanations of uptime commitments, service credits, and remedy caps so you know what you are actually getting
Red flag alerts for liability exclusions, auto-renewal traps, and termination restrictions that commonly catch UK businesses out
A clear escalation signal when the contract complexity or value means you should involve a solicitor before signing
Faster negotiation prep — know your leverage points before you get on the call with the supplier

Before you sign checklist

1
1. Identify whether you are the buyer or supplier in this SLA — your risk exposure and review priorities differ significantly depending on which side you are on
2
2. Check the service metrics section: are uptime or delivery targets defined with specific numbers, or are they described in vague terms like 'reasonable efforts'
3
3. Review the service credits and remedies clause — confirm what you actually receive if the supplier fails to meet targets and whether those remedies are your only recourse
4
4. Read the liability cap carefully — many SLAs cap total liability at one month's fees, which may be far below your actual loss if the service fails
5
5. Check the termination and exit clause for minimum notice periods, auto-renewal triggers, and any data return or deletion obligations on exit
6
6. Upload the SLA to Atornee to get a structured review flagging red flags, missing clauses, and plain English explanations before your next supplier conversation
7
7. If the contract value is above your risk threshold or the liability terms are heavily negotiated, escalate to a UK solicitor before signing

FAQ

What should I look for when reviewing a service level agreement in the UK?

Focus on five areas: how service levels are defined and measured, what happens when they are missed (service credits and remedies), how liability is capped, what the termination and notice conditions are, and whether there are any data handling obligations relevant to UK GDPR. Vague language in any of these areas is a red flag.

Are service level agreements legally binding in the UK?

Yes, an SLA is a legally binding contract under UK law once both parties have agreed to its terms. If it is incorporated into a master services agreement or a statement of work, the enforceability depends on how those documents interact. Always check which document takes precedence in a conflict.

What are the most common red flags in a UK SLA?

The most common issues are: uptime guarantees with so many exclusions they are effectively unenforceable, service credits that are your only remedy and are capped at a trivial amount, liability exclusions that remove the supplier's responsibility for consequential loss, auto-renewal clauses with short cancellation windows, and termination clauses that require six to twelve months notice to exit.

Can I negotiate an SLA with a large supplier?

Often yes, even with large vendors. Uptime targets, service credit percentages, liability caps, and termination notice periods are frequently negotiable, particularly if you are committing to a multi-year term or significant spend. Knowing exactly which clauses are problematic before the negotiation gives you a much stronger position.

Do I need a solicitor to review an SLA?

Not always. For lower-value or standard SaaS agreements, a structured AI review can give you a fast, informed read of the key risks. For high-value contracts, bespoke service arrangements, or situations where the liability exposure is significant, you should involve a UK solicitor. Atornee will flag when that threshold is likely reached.

What is the difference between an SLA and a contract?

An SLA is a type of contract, or a schedule within a broader contract, that sets out specific service performance standards and what happens if they are not met. A master services agreement or supply contract typically governs the overall commercial relationship, with the SLA sitting underneath it to define delivery obligations in detail.
