What building qualifications do you hold?

Ask your Harrow builder about any professional memberships or construction-related qualifications they have, such as NVQs or Level 2/3 diplomas in building trades. Proof of their health and safety training, like a CSCS card, is also useful to get.

Will all work comply with building regulations and planning permissions?

Make sure your builder is ready to meet all relevant building regulations and standards in Harrow, throughout your project. They should explain how they’ll communicate with building control and approvals, too.

Have you completed similar projects in Harrow before?

Understanding if a builder in Harrow has worked on projects like yours can give insight into their familiarity with challenges specific to your type of build and location. It’s also quick to view images of a builder’s past works on their MyBuilder profile.

What is the estimated timescale to complete the project?

Ask your Harrow builder for a detailed schedule. This should include important milestones in your project, like site preparation, foundation completion, structural framing, roofing, installation of utilities, interior finishes, and final inspections.

Do you provide guarantees or warranties for your work? Most building contractors and companies in Harrow provide warranties covering their workmanship and materials for a specified period, offering reassurance that issues will be addressed post-project.
