Understanding Your Rights When Contractors Are Slow

When a contractor is moving slowly or missing deadlines, it’s natural to feel frustrated – especially when home repairs or improvements are involved. Fortunately, UK law offers clear protections for consumers in these situations. Understanding your rights can help you address delays confidently and take the right steps if things don’t improve.

Your Rights Under UK Law

As a consumer, you’re protected by the Consumer Rights Act 2015 when you hire a contractor for work at your home. This law requires that any service provided – including building, decorating, or repairs – must be carried out with “reasonable care and skill,” and within a “reasonable time” if no specific deadline is agreed. If a contractor is working much slower than expected, or the delay is causing significant inconvenience, you may have grounds to take action.

The Importance of Clear Contracts and Deadlines

Having a written contract is your best defence against slow progress. A good contract should clearly set out:

  • The scope of work

  • Start and finish dates (or a clear schedule)

  • Payment terms

  • What happens if deadlines are missed

If your contract includes specific deadlines and the contractor fails to meet them without a valid reason, this could be considered a breach of contract. In these cases, you may be entitled to compensation, or even to terminate the contract and hire someone else to finish the job.

When Is a Delay Considered a Breach of Contract?

Not every delay is a breach – sometimes, unforeseen issues like bad weather or supply shortages can cause unavoidable setbacks. However, if the contractor is simply working slowly, missing agreed milestones, or failing to communicate, this may be unreasonable. If no completion date is set in the contract, the law expects the work to be finished in a “reasonable time,” judged by what’s typical for similar projects.

If delays are excessive or the contractor stops work altogether, you should raise your concerns in writing and give them a clear deadline to put things right. If they still don’t respond, you may be able to claim compensation or end the contract.

Homeowners vs. Tenants: How Rights Differ

If you own your home, you generally have full control over hiring and managing contractors. You’re responsible for the contract and any disputes that arise. For more on your options and legal protections, see our guide to help with home improvements.

If you’re a tenant, your landlord is usually responsible for repairs to the structure, plumbing, and essential services. If you’re experiencing delays with repairs arranged by your landlord, your rights are different. You should first report the problem to your landlord or letting agent. If they fail to act, you may have grounds to escalate the issue. For more details on what your landlord must fix, see our guide to landlord repair responsibilities.

Recognising When a Delay Is Unreasonable

There’s no fixed rule for what counts as an “unreasonable” delay – it depends on the size and nature of the job. For example, a small bathroom refit shouldn’t take months, while a full extension may take longer. Signs that a delay is actionable include:

  • The contractor missing agreed deadlines without explanation

  • Work regularly stopping and starting, with little progress

  • Poor communication or failure to respond to your concerns

  • The contractor abandoning the project

If you believe a delay has become unreasonable, you have the right to request a firm completion date, negotiate compensation, or ultimately take further legal action if necessary.

Understanding your rights is the first step to resolving slow contractor issues – clear communication, written agreements, and knowing when to escalate can help you get your project back on track.

Setting Clear Deadlines and Expectations in Your Contract

Having a clear, written contract is one of the most effective ways to avoid delays and misunderstandings with contractors. Before any work begins, make sure you have a signed agreement that sets out exactly what you expect, when, and how. This not only protects your rights if things go wrong, but also helps both you and your contractor stay on the same page from day one.

Why a Written Contract Matters

A written contract gives you a legal record of what was agreed, including the timeline for the project, payment terms, and the quality of work expected. If your contractor is slow or misses deadlines, you’ll have clear evidence to refer back to if you need to raise concerns or take further action. Verbal agreements can be hard to prove and may lead to disputes later.

Key Deadlines and Milestones to Include

When drafting your contract, be specific about the project’s start date, key stages (milestones), and the final completion date. For example, you might break the work into phases – such as “demolition complete by 1st June,” “electrical work finished by 15th June,” and “project completed by 30th June.” This makes it easier to track progress and spot delays early.

Consequences for Missed Deadlines

It’s important to include what will happen if your contractor doesn’t meet agreed deadlines. This might involve “liquidated damages” – a set amount deducted from the contractor’s fee for each day the work is late. Make sure any penalties are reasonable and clearly stated in the contract. Including these terms can give your contractor a strong incentive to stay on schedule.

Agreeing Realistic Timeframes

Be honest with your contractor about your expectations, but also listen to their advice about how long the work should take. Unexpected issues can sometimes cause delays, so it’s wise to allow a little flexibility for weather, supply problems, or unforeseen snags. Ask your contractor to explain their timeline, and don’t be afraid to question anything that seems vague or unrealistic.

Before you sign, it’s a good idea to find a trader and check you can trust them. Checking a contractor’s track record can help you avoid those who are known for slow work or missing deadlines.

Keeping Records of Contracts and Communication

Always keep a copy of your signed contract and any written communications, such as emails or letters, about changes to the work or timeline. If problems arise, these records will be vital in showing what was agreed and how the contractor responded to any concerns. Take notes of phone calls or meetings, and confirm any important points in writing afterwards.

By setting out clear deadlines and expectations in your contract, and keeping thorough records, you put yourself in a much stronger position to deal with delays – and to resolve issues quickly if your contractor isn’t meeting their commitments.

Communicating Effectively to Speed Up Slow Contractors

Communicating effectively with your contractor is often the quickest way to resolve delays and get your project back on track. Here’s how you can approach the situation constructively while protecting your legal position.

Approach Your Contractor Politely but Firmly

Start by raising your concerns directly with your contractor. Be polite but clear about the issues. For example, you might say, “I’ve noticed the work is behind schedule. Can we discuss what’s causing the delay and how it can be resolved?” This approach shows you are aware of the problem and expect action, but avoids confrontation, which can damage working relationships.

Document All Communications in Writing

It’s essential to keep a written record of all communications about delays. While phone calls or face-to-face conversations can be useful, always follow up with an email or letter summarising what was discussed. Written records provide clear evidence if you need to refer to the issue later or pursue legal action. Under the Consumer Rights Act 2015, having a record can support your case if you claim the contractor has not met reasonable standards or deadlines.

What to Say in Reminders or Follow-Up Messages

When sending reminders or follow-up messages, be specific about your concerns and expectations. Clearly state:

  • The original agreed deadline

  • The current status of the work

  • The impact the delay is having on you

  • What you expect to happen next

For example:
“I’d like to remind you that the kitchen installation was due to be completed by 10th May. As of today, the work is still unfinished, and this is causing disruption. Please confirm when the work will be completed, or let me know if there are any issues preventing progress.”

This approach is factual and non-accusatory, making it more likely to get a positive response.

Use Negotiation and Compromise

Sometimes delays are unavoidable due to factors like bad weather or supply issues. If your contractor provides a reasonable explanation, consider negotiating a new deadline or agreeing on revised milestones. You might also discuss incentives for early completion or penalties for further delays, but make sure any changes are confirmed in writing and signed by both parties.

When to Escalate Your Concerns

If your contractor continues to work slowly or ignores your communications, it may be time to escalate the issue. Start by sending a formal written complaint, setting out your concerns and giving a clear deadline for the contractor to respond or put things right. Mention your rights under the Consumer Rights Act 2015, which requires services to be provided with reasonable care and skill, and within a reasonable timeframe.

If there’s still no improvement, you may need to consider further action, such as withholding payment for incomplete work, seeking alternative contractors, or pursuing dispute resolution or legal action. Always keep copies of all correspondence and evidence of delays, as these will be vital if the matter goes further.

By communicating clearly, keeping records, and knowing when to escalate, you can often resolve delays without unnecessary stress or cost.

Taking Formal Action When Contractors Miss Deadlines

When informal discussions and reminders haven’t resolved the issue of slow or missed deadlines, it may be time to take formal action against your contractor. Understanding your legal rights and the proper steps to follow can help you protect your interests and, if necessary, end the contract without further hassle.

Issuing Formal Notices and Warnings

If your contractor is not meeting agreed deadlines, your first formal step should be to issue a written notice or warning. This is often called a "notice of breach" and should clearly state:

  • The specific deadlines or milestones that have been missed

  • How the contractor is in breach of the contract

  • What you expect them to do to remedy the situation (such as completing the work by a new, reasonable date)

  • A clear timeframe for them to respond or put things right

Always keep copies of any correspondence and send important notices by recorded delivery or email so you have proof they were received. This written trail will be crucial if you need to escalate the matter.

Your Right to Cancel the Contract

If the contractor continues to miss deadlines or fails to fix the problem within the time given, you may have the right to cancel the contract for breach. Under UK contract law, a "material breach" – such as failing to complete work by agreed dates – often entitles you to end the agreement and, if appropriate, hire someone else to finish the job.

Before cancelling, check your contract for any specific termination clauses or notice requirements. Even if there isn’t a written agreement, you still have rights under consumer protection laws. If you’re unsure, seeking professional advice can help clarify your position.

Writing a Cancellation Letter

To formally end a contract, you should send a clear, written cancellation letter explaining your reasons and referencing the breaches. For step-by-step guidance and a template you can use, see this letter to cancel a contract that’s been breached.

Claiming Compensation for Delays or Damages

If the contractor’s delays have caused you financial loss – such as extra accommodation costs, lost earnings, or having to pay another tradesperson to fix poor work – you may be entitled to claim compensation. The amount you can claim depends on the actual losses suffered and what was agreed in your contract.

Considering Alternative Dispute Resolution (ADR)

If you and your contractor can’t agree on a solution, court action is not your only option. Methods like mediation or arbitration – known as alternative dispute resolution (ADR) – can help you reach a fair outcome without the stress and cost of going to court. ADR is often quicker, less formal, and may be required before legal proceedings can begin.


Taking formal action can feel daunting, but following these steps ensures you protect your rights and gives your contractor every chance to put things right. If you need further help, explore our related guides for more detailed advice on each stage of the process.

Escalating Problems: Reporting and Getting More Help

When a contractor continues to work slowly or misses agreed deadlines despite your efforts to resolve things directly, it may be time to escalate the situation. Taking the right steps can help protect your rights and encourage the contractor to act more responsibly.

Reporting to Trading Standards

If you believe your contractor has breached consumer law – for example, by not delivering work with reasonable care and skill, or by failing to meet agreed deadlines under the Consumer Rights Act 2015 – you can report to Trading Standards. Trading Standards investigates businesses that break the law or treat customers unfairly, and they have the power to take action against contractors who repeatedly fail to meet legal obligations. Typical breaches include misleading information, poor workmanship, or ignoring contractual terms.

Getting Help from an Ombudsman

For unresolved disputes, you might also contact an ombudsman in England. Ombudsman services offer free and impartial dispute resolution for consumers. They can review your complaint, investigate the facts, and make recommendations or decisions that contractors are usually expected to follow. Before contacting an ombudsman, you generally need to have tried to resolve the issue directly with the contractor and allowed them reasonable time to respond.

Additional Support for Ongoing Issues

If problems persist or you’re unsure what to do next, there are further resources to help you solve an ongoing consumer problem. These services can guide you through the complaint process, help you understand your rights, and suggest the best course of action based on your situation.

You can also explore more options if you need more help about a consumer issue, such as getting advice on how to gather evidence, write formal complaints, or prepare for possible legal action.

Knowing When to Seek Legal Advice

If informal steps and official complaints do not resolve the problem, it may be time to seek legal advice. A solicitor can help you understand your rights under the contract and consumer law, and advise you on the possibility of claiming compensation or terminating the contract. Keep records of all communications, agreements, and any evidence of delays or poor workmanship, as this will strengthen your case if you need to take things further.
