The contractor you choose shapes every part of your project, from the first estimate to the final handover. A low price can hide high costs later, while the right partner saves time and stress. In this article, we explain five things to check before you sign a construction contract.
Relevant Experience
A contractor who has built projects like yours will understand the risks before they arise. Ask to see similar work and speak to the clients behind it.
Questions to ask:
- Have you delivered projects of this size and type?
- Can we visit a completed project?
- May we speak to recent clients?
Licences and Insurance
Proper licences and insurance protect you if something goes wrong. Always ask for written proof rather than taking it on trust.
Documents to check:
- Trade licences and registrations
- Public liability insurance
- Employer's liability insurance
- Health and safety accreditations
A Clear, Detailed Quote
The best quotes leave nothing to guesswork. They set out what is included, what is not and how changes will be priced.
Look for:
- An itemised breakdown of costs
- Defined allowances and exclusions
- A realistic programme
- Payment stages tied to progress
Good Communication
You will speak to your contractor every week for months. How they communicate during the tender is a good sign of how they will communicate on site.
Signs of a good communicator:
- Prompt, clear answers to questions
- A named contact for the project
- Regular progress reports
- Honesty about risks and delays
Aftercare and Warranties
A finished building still needs support. Find out how defects are handled after handover and what warranties cover the work.
Agree before you start:
- The length of the defects period
- How to report and track issues
- Warranties on materials and workmanship
- Maintenance guidance at handover
Choosing a contractor is choosing a partner. Take the time to check experience, paperwork and communication, and your project starts on solid ground.
