Top Questions to Ask a Builder During a Free Home Survey
A free home survey is your best chance to vet a contractor before work begins. Learn the essential questions to ask regarding costs, timelines, and credentials to ensure a smooth UK home renovation.

Inviting a builder into your home for a survey is the first real step toward turning your renovation dreams into a reality. This guide explains how to navigate that initial meeting, ensuring you extract the vital information needed to compare quotes and choose the right partner for your project.
Understanding the Scope and Logistics
Before you get into the fine details of aesthetics, you need to know if the builder truly understands the scale of what you are proposing. Whether it is a £50,000 loft conversion or a £15,000 bathroom refit, the survey is the time to identify potential structural hurdles. Ask the builder how they plan to manage the site daily. Will they need a skip on the driveway, and do they handle the local council permits for it?
You should also enquire about their specific experience with your property type. Victorian terraces in London require a different approach than 1970s semi-detached homes in Manchester due to lath-and-plaster walls or specific damp-proofing needs. If your project requires structural changes, ask if they have a preferred structural engineer or if you need to appoint one independently to provide the calculations before they start.
Timelines and Project Management
In 2026, the UK construction industry remains busy, and the best builders often have lead times of three to six months. During the survey, be direct about your desired start date and ask for an honest appraisal of how long the work will take. A kitchen refurbishment might take three weeks, but a full-wrap extension could easily span four to six months depending on the weather and supply chains.
Ask who will be your main point of contact. Will it be the person standing in your hallway now, or a dedicated site foreman? Understanding the chain of command prevents communication breakdowns later. You should also ask about their working hours; most UK crews work 8:00 am to 4:30 pm, but it is worth confirming if they work Saturdays to speed up the finish date.
Budget, Payments, and VAT
Money is often the most awkward topic, but it is the most critical. You must clarify if the figure they provide is a 'quote' (a fixed price) or an 'estimate' (a best guess that could change). In the current economic climate, material costs can fluctuate, so ask how long their quote remains valid. Typically, a builder will hold a price for 30 days.
- How do you handle staged payments? (e.g., 10% deposit, then 30% after first-fix).
- Is VAT included in the final figure? (Remember, most residential work is 20%, though some energy-saving installs are 0%).
- Do you have a contingency recommendation? (Most experts suggest keeping 10-15% of the project value aside for 'surprises').
- How are 'extras' or changes to the plan billed once work has started?
Qualifications and Insurance
Never feel embarrassed to ask for proof of credentials. A reputable builder will be happy to show they are professional and protected. If they are handling gas or electrics, they must use tradespeople who are Gas Safe registered or NICEIC certified. Ask if they are members of the Federation of Master Builders (FMB) or TrustMark, as these organisations require vetted standards and offer dispute resolution services.
Insurance is a non-negotiable. Ensure the builder has Public Liability Insurance (usually to a minimum of £2 million or £5 million) to cover any damage to your property or neighbours. It is also wise to ask about their 'all-risk' insurance, which covers the work in progress against fire or theft. If they cannot provide these details during or shortly after the survey, it is a significant red flag.
References and Recent Portfolio
A builder is only as good as their last three jobs. Ask for the addresses of projects they have completed in the last 18 months that are similar to yours. Don't just look at photos on a tablet; ask if it is possible to speak with a previous client. Most proud homeowners are happy to give a quick five-minute phone testimonial if the builder did a great job.
- Can I see a project currently in progress to see how you maintain a site?
- Do you have experience working with my local planning department?
- Are there any specific challenges you foresee with this particular design?
- What kind of aftercare or warranty do you provide on the workmanship?
Finalising the Details
As the survey wraps up, ask when you can expect the written quote. A professional should typically get a detailed breakdown to you within 7 to 10 working days. If they take three weeks just to send a price, they may be too busy to give your actual build the attention it deserves. Make sure the quote is itemised so you can see exactly where your money is going, from demolition and waste removal to the final lick of paint.
Preparing these questions ensures you remain in control of the process. A survey is a two-way interview; you are looking for technical competence, but also for someone you can trust around your family and your home for several weeks. Clear communication at this stage sets the tone for a successful, stress-free refurbishment that adds genuine value to your property.
