Written in November 2024. Checked for changes in the law in November 2026. This is general information, not legal advice.

When a contractor fails to maintain progress on a construction project, it can disrupt timelines and lead to significant delays. Sending a formal letter addressing slow progress or work delay is an important step in holding the contractor accountable and ensuring the project moves forward. Below is a guide to drafting such a letter, along with a sample template.

Why Send a Letter About Slow Progress?

This letter serves multiple purposes:

  • Documentation: Creates a formal record of the issue for future reference or potential legal action.
  • Request for Action: Urges the contractor to address the delay and propose a revised plan to meet deadlines.
  • Legal Protection: Demonstrates that you made efforts to resolve the matter, which may be required under the contract.

Key Elements of the Letter

Ensure your letter includes the following:

  • Project details: Include the project name, address, and relevant dates.
  • Describe the issue: Clearly outline how the contractor has failed to maintain progress.
  • Reference the contract: Cite relevant clauses about project timelines or performance expectations.
  • Demand for action: Request a plan to get the project back on track, along with a deadline for response.

Subject: Notice of Failure to Maintain Progress  

Dear [Contractor’s Name],  

I am writing to formally address concerns regarding the lack of progress on the project at [Project Address], which began on [Start Date]. According to our contract dated [Contract Date], the agreed timeline requires [specific milestones, e.g., "completion of structural work by [Milestone Date]."]  

As of today, the following issues have been noted:  
1. [Example of slow progress, e.g., "Foundation work remains incomplete, despite the agreed deadline of [Date]."]  
2. [Another example, e.g., "No significant progress has been made on installing the roofing."]  

These delays are jeopardizing the project timeline and causing [specific consequences, e.g., "financial loss due to additional rental costs."] Under Clause [Contract Clause] of our agreement, you are obligated to maintain reasonable progress toward the agreed deadlines.  

To resolve this matter, I request the following actions:  
1. Submit a written explanation for the delays.  
2. Provide a revised project timeline detailing how you intend to complete the work and meet the remaining milestones.  

Please respond to this notice by [Specific Deadline, e.g., "seven days from receipt of this letter"]. If I do not receive a satisfactory response or observe significant improvement in progress, I will have no choice but to consider alternative remedies, including engaging another contractor and seeking compensation for any additional costs incurred.  

I look forward to your prompt response and a resolution to this matter.  

Sincerely,  
[Your Full Name]  

What to Do After Sending the Letter

Once the letter is sent, take the following steps:

  • Document delivery: Send the letter via recorded delivery or email with a read receipt to confirm the contractor received it.
  • Monitor progress: Keep an eye on whether the contractor takes corrective action or responds with a plan.
  • Follow up: If there’s no response by the deadline, escalate the matter by consulting a solicitor or exploring dispute resolution options.

Final Thoughts

A well-written letter addressing slow progress shows that you take the issue seriously and sets clear expectations for the contractor. By documenting your concerns and providing a clear path for resolution, you create a foundation for either moving the project forward or pursuing remedies for breach of contract.
