LinkedInWhatsAppEmail

Have you completed similar projects?

Ask for examples that match your project type, value, occupied-property constraints and level of finish. Discuss what went well and what challenges had to be managed.

Who will manage my project?

Ask who your main contact will be, how often they will be on site and who has authority to agree changes, instructions and programme decisions.

What is included and excluded?

Ask the contractor to identify assumptions and exclusions clearly. Common areas include scaffolding, temporary works, waste, decorating, external works, utility changes and client-supplied products.

How will variations be priced?

Agree the process for changes before work starts. Ask whether variations will be quoted in advance and how they affect the programme.

What programme do you propose?

Ask for the likely start date, duration, sequencing, long-lead items and any decisions or information you need to provide to keep the programme moving.

What insurance and compliance information can you provide?

Request the information relevant to your project and clarify responsibilities for health and safety, building control, design and specialist works.

Frequently asked questions

How many builders should I speak to?

There is no fixed number. The aim is to compare enough suitable companies to understand the market while keeping the process manageable and focused on contractors who genuinely fit the project.

Should every answer be written down?

Important commercial, scope and programme points should ultimately be reflected in the written quotation, specification, programme or contract rather than relying only on verbal discussions.

Can I post my project before every detail is final?

Yes, provided the information is honest about what is known and what is still developing. Drawings, budget range, location and target timing help contractors assess whether the opportunity fits.
