How Long Do Restrictive Covenants Last? A Guide for UK Businesses

Whether you’re starting a new business, hiring your first team member, or negotiating a contract, restrictive covenants are likely to come up sooner or later. They pop up everywhere-from employment contracts and partnership agreements to property deeds and supplier deals.

But they can also be confusing-especially when you’re trying to figure out “how long does a covenant last” or what’s actually enforceable in the UK. This guide will break down everything you need to know about restrictive covenants, including what they are, how long they can last, and the crucial legal rules that shape their duration. By understanding these basics, you’ll be better protected and feel more confident when dealing with covenants in your contracts or agreements.

Let’s get started-so you can keep your business protected, compliant, and on a path to long-term success.

What Are Restrictive Covenants?

Restrictive covenants are special clauses found in many types of contracts. Their purpose is simple: they restrict (that is, “limit”) a party’s behaviour in some way, usually after a contract comes to an end.

Common places you’ll find restrictive covenants include:

• Employment contracts-preventing employees from joining competitors or soliciting clients after leaving
• Business sale agreements-stopping sellers from setting up rival businesses
• Supplier and distribution contracts-putting limits on who a business can trade with
• Property deeds or leases-restricting the way land or buildings can be used

The idea is to protect key business interests-your customer base, your confidential information, your hard-earned reputation. But UK law is very careful not to let these clauses go too far, so there are strict rules about how they must be written and-most importantly-how long they can last.

For more detail about what they look like in business contracts, see our guide: Restrictive Covenants In Employment Contracts: Meaning, Types & How To Use Them Effectively.

Why Does the Length of a Covenant Matter?

Many business owners, managers, and employees will at some point ask: how long do restrictive covenants last? The reason is simple-duration is one of the key factors courts look at when deciding whether a covenant can be enforced.

If a covenant lasts too long, it’s quite likely to be found “unreasonable”-and if that happens, it might not be enforceable at all. But make it too short and you risk not properly protecting your business interests. Striking the right balance is vital.

How Long Does a Restrictive Covenant Last in Employment Contracts?

The most common place you’ll come across questions about how long covenants last is in employment contracts. Typical restrictive covenants here include:

• Non-compete clauses-stop an employee from working for a competitor after leaving
• Non-solicitation clauses-prevent ex-employees from poaching your clients or staff
• Non-dealing clauses-stop them from doing business with your clients or suppliers
• Confidentiality clauses-protect your sensitive information even after employment ends

So, how long do these covenants last? There’s no “one size fits all” answer, but some key principles apply:

• Most restrictive covenants only apply for a set period after employment ends-often 3, 6 or 12 months.
• The time period must be “reasonable” given the nature of the business, the employee’s role, and what the covenant is protecting.
• Courts generally won’t enforce a covenant if it lasts longer than is needed to protect your legitimate interests.
• Confidentiality clauses can sometimes last indefinitely (for as long as information remains confidential).

For example, it’s common to see non-compete clauses lasting up to 6 months for sales managers or key executives. But if you tried to make it 2 years, you’d need a very strong justification for why such a long period is necessary.

There are no set statutory maximums on duration in UK law, but the courts have provided plenty of guidance in cases over the years. Generally:

• Up to 6 months: Usually seen as “on the safer side” for non-compete or non-solicit clauses.
• 6-12 months: May still be enforceable, especially for senior roles, but must be well-justified.
• More than 12 months: Rarely upheld, except in unique circumstances (like a business sale).

The bottom line? Always tailor restrictive covenants to your business and the role-not longer than genuinely necessary. And avoid generic templates that might accidentally overstep what’s reasonable!

How Long Do Restrictive Covenants Last in Business Sale Agreements?

When a business is sold, restrictive covenants are there to stop the seller from undermining the value of what they’ve just sold. Common clauses include:

• Preventing the seller from starting a competing business
• Stopping them from soliciting former clients or staff
• Sometimes restricting them from dealing with the same customers or suppliers

So how long does a covenant last in this scenario? Here, courts are often a bit more generous-as buyers need extra protection after buying a business. Restrictions of 2-3 years are not unusual and can sometimes be longer, depending on what’s “reasonable and necessary” for the business being sold.

But again-the test is always whether the duration is justified to protect the legitimate interests of the buyer, not simply to prevent competition for as long as possible.

How Long Do Restrictive Covenants Last in Property (Land) Law?

Restrictive covenants aren’t just for employment and business deals-they’re also very common on land and property. Here, a restrictive covenant can:

• Limit how land can be used (e.g., “no commercial buildings”)
• Stop certain types of businesses operating on a site
• Prevent owners from making alterations such as adding extra floors or running a specific type of trade

Unlike in contracts for people, restrictive covenants “attached” to property can sometimes last indefinitely. They stay with the land and bind future owners until they’re removed or changed (for instance, by a Deed of Variation or a court order). This means a covenant added decades ago could still affect your property today!

This is one area where specialised advice is crucial-because the law around property covenants is complex and depends heavily on land registration, the wording of the deed, ongoing use, and changes in the area.

What Makes a Covenant’s Duration “Reasonable”?

As you can see, there isn’t a fixed answer to how long restrictive covenants last in UK law-it all depends on context. Here are some key factors courts look at when deciding if a covenant’s length is “reasonable”:

• The type of business and industry norms: Some sectors (like tech or finance) move quickly, so a shorter time period is justified; others (like manufacturing or professional services) may support longer periods for protecting customer relationships.
• The employee’s (or seller’s) seniority and access: Senior executives, business owners, or key staff may justifiably face longer restrictions than junior or “rank and file” team members.
• What the covenant is protecting: Is it trade secrets, client relationships, or something else? The more valuable or long-lasting the “interest” being protected, the longer a covenant can sometimes last.
• Geographical reach: A local café owner will usually have a much more limited “area of effect” than the seller of a national franchise.
• Risks of competition or misuse: The more risk posed to the business, the stronger and sometimes longer the covenant may need to be.

In short-UK law tries to balance fair protection of genuine business interests against someone’s right to work or trade freely. The moment a covenant feels more like a punishment than a fair safeguard, it becomes at risk of being struck down.

How Do I Make Sure My Restrictive Covenants Are Enforceable?

This is a big concern for businesses of all sizes. Some practical steps to strengthen your covenants are:

• Be specific-spell out what you need to protect (clients, staff, suppliers, confidential info, etc.)
• Set clear, justified time periods-not too short, but never longer than needed; 3-6 months for non-competes is “safe” for most employees; up to 2-3 years for business sales may be upheld with good justification.
• Tailor the restrictions to the situation-avoid “one size fits all” templates!
• Avoid going global or infinite unless absolutely needed, as the wider and longer the restriction, the more likely it is to be unenforceable.
• Get professional legal input. This is one area where legal advice pays off, as a poorly drafted covenant could leave you unprotected or facing disputes.

What If I Want to Change or Remove a Covenant?

If you’ve inherited a contract-say, from a previous employer, a former partnership, or in a property deal-and the restrictive covenants don’t feel right for your circumstances, you do have options:

• Renegotiate contract terms (with the other party’s agreement)
• Use a Deed of Variation to change or remove the covenant
• For land covenants, you may need to apply to the Land Registry or to court for modification or discharge if circumstances have changed

Never just ignore a covenant or break it without advice. Breaching an enforceable covenant can land you in serious legal trouble-including lawsuits and damages.

What Happens if a Covenant Lasts Too Long?

If a restrictive covenant is found to last “longer than necessary,” UK courts have the power to refuse enforcement altogether. They typically won’t “rewrite” the clause to reduce the time-the whole thing could be struck out. This means you could be left unprotected if you rely on a clause that’s overreaching or poorly drafted.

This is exactly why it’s important to get covenants right the first time, with tailored, up-to-date legal input for your situation and industry.

Are There Alternatives to Restrictive Covenants?

Absolutely. Depending on what you need to protect, you might also consider:

• Robust confidentiality (NDA) agreements
• Well-drafted employment or consultancy service agreements with clear obligations
• Intellectual property protections (like trademarks or copyright clauses)

These tools often work alongside restrictive covenants to provide the best protection-without overstepping the bounds of fairness or reasonableness.

Key Takeaways

• The duration of restrictive covenants in the UK depends on the type of contract and what it’s protecting-there’s no universal rule.
• In employment contracts, 3-6 months is “safe” for most roles, while 6-12 months may be justified for senior or specialist roles. More than 12 months is rarely enforceable outside of business sales.
• For business sales, covenants of 2-3 years can be reasonable if they are needed to protect the buyer.
• Land or property covenants can last indefinitely and remain attached to the land until changed or removed.
• Enforceability comes down to reasonableness-tailor covenants directly to your business circumstances.
• Get professional help-to make sure your covenants are the right length and are properly drafted for maximum legal protection.
