Questions to Ask When Choosing your Builder
June 9, 2026
When interviewing builders for a bespoke UK build, focus on verifying their specific experience with one-off projects, contract structures, and site management.
Clarifying these aspects prevents budget overruns and timeline delays, keeping your construction aligned with planning regulations and self-build mortgage requirements.
Project Experience & Track Record
- Have you completed bespoke builds of a similar architectural style or scale to my project?
A builder comfortable with standard brick-and-block extensions may not have the expertise to manage complex structural glazing, passive house standards, or modern timber frames.
- Can I contact previous clients and view a similar home you have built?
Speaking directly with homeowners about the builder's reliability, snag-resolution process, and post-completion support is essential. At Rawlinson Construction, we even go a step further and can arrange for you to view our past projects, and even those still in progress so you can see the quality of workmanship and even meet our own in-house tradesmen.
- Do you have experience acting as the principal contractor under CDM (Construction Design and Management) regulations?
By law in the UK, your builder must have the capacity to manage health and safety, site security, and welfare facilities for all on-site workers.
Contracts & Cost Management
- Which construction contract do you prefer to use?
Avoid handshake agreements. Standard UK industry contracts like the Federation of Master Builders contracts or JCT (Joint Contracts Tribunal) offer clear protection for one-off bespoke builds.
- Is VAT included in your quote, and how do you handle material price volatility?
Ensure your quote clarifies whether prices are fixed or variable, as some materials may fluctuate in cost over the duration of the build.
- What is your payment schedule, and how does it align with stage releases?
Avoid large upfront deposits. Tie your payment stages to concrete milestones and structural warranty inspections, which is critical if you are utilising a self-build mortgage. - At Rawlinson Construction we have a structured approach and you only pay for work that has been completed and verified at each major milestone. Payments are directly tied to tangible progress, allowing you to monitor the development of your dream home with absolute peace of mind.
Site Management & Communication
- Who will be on-site managing the day-to-day build?
Clarify whether the lead contractor will be on-site full-time, or if the project will be heavily delegated to subcontractors whose experience you cannot verify. For us at Rawlinson Construction, one of the two company directors, both of which are experienced builders themselves, also visit the site frequently, and often daily, to check on progress and to be on hand to answer customer questions.
- What is your process for managing variations and "design creep"?
Bespoke builds frequently evolve during construction. Ask how they process design alterations, document changes, and communicate those cost impacts to avoid unpleasant final bills.
- How do you handle site utilities, access, and neighbour relations?
A bespoke build generates significant material deliveries, waste, and disruption. Ask how they plan to secure the site, manage skips, and maintain good relationships with neighbouring properties in the UK.
Warranties & Compliance
- What structural warranty do you provide upon completion?
Verify if they offer recognised warranties (e.g. from the Checkatrade directory guidelines or specific structural warranty providers) to protect your investment.
- Will you handle Building Control sign-offs and local planning condition discharges?
Clarify who is responsible for liaising with the local authority, scheduling building control inspections, and proving compliance with UK building regulations.
