Non-solicitation Clauses in UK Construction Employment and Contractor Agreements

A non-solicitation clause can protect a construction business from losing clients, site staff or subcontractor relationships when someone leaves, but a badly drafted clause can be hard to enforce.

Many founders make the same mistakes: they copy a broad restraint from another industry, they apply the same wording to employees and independent contractors, or they rely on a clause that says someone cannot contact “any client” without defining who that means. Another common problem is leaving the clause in a template agreement and assuming it will work later if a project manager, estimator or freelance site supervisor walks away with key contacts.

For construction companies in the UK, the detail matters. The role, the relationships being protected, the geographic spread of projects, the length of the restriction, and whether the person had real influence over clients or workers all affect whether the clause is likely to hold up. This guide explains what a non-solicitation clause for construction company agreements actually does, what legal issues to check before you sign, where businesses get caught out, and how to make these clauses more practical and defensible.

Overview

A non-solicitation clause stops a departing worker or contractor from actively approaching certain clients, employees, labourers, suppliers or subcontractors for a set period after the relationship ends. In the UK, these clauses can be enforceable, but only if they go no further than reasonably necessary to protect a legitimate business interest.

• Identify exactly who is being protected, such as named clients, active prospects, employees, agency workers or specialist subcontractors.
• Match the clause to the person’s role, because a senior commercial manager should not have the same restriction as a short-term labour-only contractor.
• Set a realistic duration, often linked to project cycles and handover periods rather than arbitrary long periods.
• Separate non-solicitation from non-dealing, confidentiality and non-compete wording instead of blending them into one unclear clause.
• Check that the clause appears in the signed employment contract or contractor agreement before the relationship starts or changes.
• Make sure the wording reflects how your construction business actually wins work and manages site teams.

What Non-solicitation Clause for Construction Company Means For UK Businesses

A non-solicitation clause is usually about preserving relationships that your business has paid to build. In construction, that often means repeat clients, framework contacts, bid opportunities, trusted site staff and specialist subcontractors.

The clause does not usually stop all competition. Instead, it tries to stop active poaching after someone leaves. That distinction matters because UK courts tend to look closely at whether the restriction is targeted and justified.

What the clause usually covers

For a construction company, non-solicitation wording often covers one or more of the following groups:

• Clients or customers the person dealt with in the last 6 to 12 months.
• Prospective clients where the person had material involvement in tenders, pricing or relationship management.
• Employees, temporary workers or agency staff.
• Subcontractors and specialist trades, such as electricians, steel fixers, scaffold providers or groundworks teams.
• Suppliers where relationships are commercially sensitive or difficult to replace.

A good clause says which group is protected and why. A weak clause lumps everyone together and creates uncertainty.

Why construction businesses use these clauses

Construction businesses often rely on relationship-driven work. A contracts manager may know exactly which developer contacts are likely to tender the next phase. A project lead may have day-to-day influence over subcontractors who could move with them to a competitor. A recruiter or operations lead may know which site managers are open to moving.

That is where founders often get caught. They assume confidentiality wording alone is enough. It often is not. A former worker might not misuse confidential documents, but they may still call clients or site staff they know personally.

Non-solicitation clauses are commonly used to protect legitimate business interests such as:

• Client goodwill and repeat work.
• The stability of a trained workforce.
• The continuity of specialist subcontractor networks.
• Commercial opportunities tied to bids, pricing and pipelines.

Employees and contractors are not the same

A non-solicitation clause for construction company agreements should not be copied word for word across employment contracts and contractor agreements. The legal analysis is similar in some ways, but the commercial context is often different.

For employees, restraint clauses are usually examined as post-termination restrictions. The business must show the clause protects a legitimate interest and goes no further than reasonably necessary.

For independent contractors, the same broad principle often applies in practice, especially where the clause restrains trade. Courts still tend to scrutinise restrictions carefully. The fact that someone is labelled a contractor does not mean any restriction will be accepted just because the contract says so.

Before you classify someone as a contractor, it is worth checking whether the wider agreement reflects the real relationship. A mismatch between reality and paperwork can create multiple legal issues, not just around restrictive covenants and employee-contractor status.

What non-solicitation does not automatically do

A non-solicitation clause is not a catch-all. It does not automatically stop a former employee or contractor from:

• Working for a competitor.
• Accepting approaches from clients if the clause only prohibits active solicitation.
• Using general skill and experience gained in the role.
• Trading in the same sector after the restriction period ends.

This is why drafting matters. If your real concern is that a person should not service clients they previously managed, a non-dealing clause may be more appropriate than a clause that only bans solicitation. If your concern is confidential pricing data or tender strategy, confidentiality obligations may do more of the heavy lifting.

Legal Issues To Check Before You Sign

The enforceability question usually turns on reasonableness. Before you sign a contract, you need to know what business interest is being protected and whether the wording is proportionate to that risk.

1. Is there a legitimate business interest?

UK law does not usually allow restraints simply to prevent competition. The clause should protect something more specific.

In a construction setting, legitimate interests often include:

• Goodwill with clients and developers.
• Relationships with key subcontractors and labour providers.
• Retention of employees or teams on live projects.
• Confidential commercial information, such as rates, margins and tender strategy.

If the person had no real contact with these relationships, the clause becomes harder to justify.

2. Is the restriction tailored to the role?

The same clause should not be used for every person in the business. A managing estimator with access to pipeline data may justify broader wording than a short-term site operative. A freelance quantity surveyor engaged for one package should not necessarily be restricted from dealing with every client group the company has ever worked with.

Before you hire your first worker into a senior commercial role, or before you engage a consultant who will be client-facing, it is worth tailoring the wording to the access and influence that role actually carries.

3. Is the duration realistic?

A long restriction is not automatically invalid, but it does attract more scrutiny. In many construction relationships, 3, 6 or 12 months may be easier to justify than a longer period, depending on the role and project cycle.

The right duration often depends on factors such as:

• How long client relationships remain active after departure.
• Whether the person is involved in annual frameworks or one-off projects.
• How quickly your business can hand over relationships to another team member.
• Whether the person had influence over a live tender pipeline.

A founder’s instinct is sometimes to choose the longest period possible. That can backfire if the clause ends up looking excessive.

4. Who counts as a protected client or contact?

A clause that refers to “any client” or “any contact” may be too vague or too wide. The agreement should define the protected group with more care, ideally in written terms that match the role.

Common approaches include limiting the clause to people or businesses the individual:

• Worked with or had material contact with during a specified period before termination.
• Was responsible for managing.
• Received confidential information about.
• Dealt with in relation to tenders, estimates or negotiations.

This matters in construction because businesses often have a wide ecosystem of developers, consultants, main contractors, subcontractors and labour providers. A blanket restriction can be difficult to justify.

5. Are the promises separated clearly?

Good contract drafting separates different restrictions. This makes the agreement easier to understand and easier to rely on later.

Your contract may need separate clauses for:

• Confidentiality, covering pricing, tender strategy, client lists and technical know-how.
• Non-solicitation of clients or prospects.
• Non-solicitation of employees, labour and subcontractors.
• Non-dealing with certain clients, where justified.
• Return of company property and deletion of retained information.

When everything is merged into one dense paragraph, the main risk is uncertainty. That creates room for arguments later about what the clause actually prohibited.

6. Was the clause properly introduced?

A well-drafted clause can still be difficult to rely on if the contract process was sloppy. Before you rely on a verbal promise, check that the signed agreement actually contains the restriction and that the person had notice of it.

This issue often arises when:

• An employee starts work before the written contract is signed.
• A contractor begins on site under a purchase order or email chain, with the full consultancy agreement signed later.
• A promotion or role change increases access to clients, but the old contract is never updated.

If the role becomes more senior, fresh terms may be needed. Otherwise, an old generic clause may not fit the new reality.

7. Do the facts support enforcement?

A clause is only one part of the picture. If there is a dispute later, the business may need evidence about who the person dealt with, what relationships they managed and what contact happened after departure.

Practical records can make a real difference, including:

• Job descriptions and role summaries.
• Client allocation records.
• Tender participation notes.
• Exit communications and reminders about restrictions.
• Evidence of who initiated contact after termination.

This is especially useful in construction, where relationships can move across mobile numbers, personal contacts and informal site communications.

Common Mistakes With Non-solicitation Clause for Construction Company

The biggest mistake is using a clause that sounds tough but is not tied to the real commercial risk. Construction businesses often need precision more than aggressive wording.

Using one template for every role

A junior administrator, a site supervisor and a commercial director do not create the same risk profile. If every agreement uses identical restrictions, the clause may look like a standard restraint rather than a considered protection of specific interests.

Role-based drafting is usually more sensible. That does not mean rewriting every contract from scratch, but it does mean adjusting protected contacts, duration and scope.

Protecting people the individual never dealt with

Founders often try to cover every current and future client, subcontractor and worker. That approach can make the clause too broad. If a freelance health and safety consultant never dealt with your clients directly, a wide client non-solicitation provision may be hard to justify.

A narrower clause linked to the actual relationships the person handled is often stronger.

Confusing non-solicitation with non-dealing

These are different restrictions. A non-solicitation clause usually stops active poaching. A non-dealing clause can go further and stop the person from doing business with certain clients even if the client makes the first move.

Businesses sometimes assume their non-solicitation wording covers both situations. It often does not. Before you sign, decide what problem you are really trying to solve.

Ignoring subcontractor and labour supply risks

Construction businesses often focus on clients and forget that workforce stability is just as commercially sensitive. A departing manager who persuades a gang of trusted subcontractors or key site staff to move can cause immediate disruption on live jobs.

If that is a real risk in your business, the agreement should deal with it directly. The wording should identify whether it applies to employees only, or also to agency workers, labour-only subcontractors and specialist trades.

Using excessive time periods

A 24-month restriction may feel safer, but longer is not always better. If your projects are shorter, your client handovers are quick, or the person’s role was limited, a long period can look hard to justify.

The stronger approach is to explain why the chosen period makes commercial sense. A realistic timeframe is usually easier to defend than a maximal one.

Forgetting the wider contract package

Non-solicitation clauses do not work in isolation. Construction companies often miss other contract terms that support them, such as:

• Clear confidentiality obligations.
• Intellectual property wording for drawings, methods or tender material created by consultants.
• Notice period provisions that allow for handover.
• Garden leave wording in employment contracts, where appropriate.
• Return of devices, documents and access credentials on exit.

If the surrounding contract is thin, your practical protection may be weaker even if the restraint clause itself looks decent.

Relying on labels instead of reality

Some businesses assume that calling someone self-employed makes it easier to impose stronger restrictions. That is not a safe assumption. Courts usually care more about substance than labels.

Before you accept the provider's standard terms, or before you issue your own contractor agreement, check that the actual working arrangement matches the contract and that the restriction is still reasonable in that context.

FAQs

Are non-solicitation clauses enforceable in the UK construction sector?

Yes, they can be, but only if they protect a legitimate business interest and are no wider than reasonably necessary. Enforceability depends heavily on the wording, the person’s role and the facts.

Can a construction company stop a former worker from contacting subcontractors?

Sometimes. If the subcontractor relationships are commercially important and the clause is drafted carefully, a restriction on soliciting subcontractors may be justified. It should usually be limited to relationships the person actually handled or influenced.

What is a reasonable time limit for a non-solicitation clause?

There is no single fixed rule. Many clauses use 3, 6 or 12 months, depending on the role and the business cycle. A period that matches real client or workforce handover needs is usually easier to justify than an arbitrary longer term.

Should employees and contractors have the same clause?

Usually not. The restriction should reflect the type of relationship, the individual’s access to clients or staff, and the commercial risk. Using the same clause across all agreements is a common drafting problem.

Does a non-solicitation clause stop a former employee from working for a competitor?

No, not by itself. A non-solicitation clause usually targets poaching of clients, staff or contacts. If you want to restrict work for a competitor, that is a different type of clause and it will also need careful justification.
