Choosing the Right Builder for Your Extension Project

Selecting a builder is the most critical decision in any home improvement journey. A high-quality extension can transform your lifestyle and add significant value to your property, but the process requires a partner who offers more than just a competitive price.

At V3 Build, we’ve spent over 25 years building a reputation across Newton Abbot, Exeter, and the South West. We know that trust is built on transparency, qualification, and a proven track record. Here is our guide to vetting and choosing the right contractor for your project.

1. Verification and Accreditations

In 2026, a reputable builder should be able to provide immediate proof of their professional standing. Don’t take verbal assurances; ask to see physical or digital certificates.

  • Insurance: At a minimum, a builder must have Public Liability Insurance. For larger extensions, Employer’s Liability Insurance is also essential if they use a team.

  • Trade Bodies: Membership in organizations like the Federation of Master Builders (FMB) or TrustMark indicates that a builder has been independently vetted for their financial history, site safety, and quality of work.

  • Specialist Certifications: Ensure that specific trades within the team are properly registered—for example, Gas Safe for boiler relocations and NICEIC or NAPIT for electrical work.

2. The Power of Local References

A builder who has worked extensively in Devon will understand local ground conditions and have established relationships with local planning authorities in Teignbridge, Torbay, or Exeter.

  • Visit a “Live” Site: Ask if you can visit a current project. This allows you to see how the team manages a site—is it tidy, organized, and respectful of the neighbors?

  • Speak to Past Clients: A quality builder will happily put you in touch with previous customers. Ask them three specific questions: Was the project delivered on budget? Was the communication consistent? Would you hire them again?

3. Quotes vs. Estimates

Understanding the financial breakdown of your extension is vital for avoiding “bill shock” later in the project.

  • The Estimate: This is a rough guess and is not legally binding. It is useful for initial feasibility but should never be the basis of a contract.

  • The Fixed Quote: This should be a detailed, itemized document based on your architectural drawings. It should clearly state what is included (e.g., skip hire, materials, VAT) and what is not.

  • Payment Schedules: Never pay the full amount upfront. Reputable builders like V3 Build work on a staged payment plan, where you pay for work as it is completed and signed off by Building Control.

4. Communication and Chemistry

You will likely be working with your builder for several months. If you find communication difficult during the quoting stage, it will almost certainly become harder once the walls are down.

  • Points of Contact: Confirm who your daily point of contact will be. Is it the business owner, or a dedicated site manager?

  • Subcontractors: Many main contractors use specialist subcontractors. Ask how long they have worked with their plumbers or electricians to ensure a cohesive, reliable team.

Why V3 Build Stands Out

Based in Kingskerswell, we are a family-run business that prides itself on “quality, reliability, and value.” We understand that we aren’t just working on a building; we are working in your home. Our 25 years of experience across South Devon allow us to manage every aspect of your extension, from initial groundworks to the final decorative finish.
