Demolition Operative Interview Questions UK: 8 Real Questions and What Interviewers Want

Applying for a Demolition Operative job in the UK? Here is what you are likely to be asked. These questions come from our Demolition Operative question bank of 12 questions, written for UK employers at junior level.

Eight Demolition Operative interview questions, and what the interviewer is thinking

1. What do you understand about the demolition plan and BS 6187, and how does that affect the way you work day to day?

Why they ask: They want to know you appreciate that demolition follows a planned, engineered sequence rather than just knocking things down.

2. Why do you want to be a demolition operative, and what do you think makes a good one?

Why they ask: They want to confirm you are motivated and understand the risks and demands of the work.

3. How do you control dust and silica when breaking out concrete or masonry?

Why they ask: Respirable crystalline silica causes serious lung disease, so they check your understanding of the control hierarchy.

4. What should happen before and during hot cutting with oxy-fuel equipment?

Why they ask: Fire and explosion risks from cutting gear are a big concern on demolition sites.

5. Why is a refurbishment and demolition asbestos survey needed, and what is your responsibility as an operative?

Why they ask: They need to know you respect asbestos controls and your own limits.

6. What needs to happen with services such as gas, electric and water before any demolition work begins?

Why they ask: Live services in a building being demolished are a serious hazard, so they check you understand isolation.

7. You are breaking out a wall and notice new cracks opening above you and the structure seems to be moving. What do you do?

Why they ask: They are testing whether you recognise structural instability and react immediately.

8. Tell me about a time you spotted a hazard before work started and what you did about it.

Why they ask: They want evidence that you are observant and proactive about safety.

A sample answer to question 1

What do you understand about the demolition plan and BS 6187, and how does that affect the way you work day to day?

BS 6187 is the UK code of practice for demolition, and it requires a demolition method statement based on a structural survey, with an agreed sequence, exclusion zones and controls for dust, noise, services and waste. As an operative, I need to read and sign the plan and the RAMS before starting, understand the sequence for my area and stick to it. Typically that means working from the top down, keeping the structure stable at every stage, and never undermining a wall or removing a supporting element unless the plan says so. Temporary supports and propping may be in place, and I must not disturb them. If conditions differ from the plan, for example if I find a hidden steel beam, a void or a different construction, I stop and tell the supervisor so the plan can be reviewed, rather than carrying on and adapting it myself.

Common mistake to avoid: Freelancing away from the plan; removing supports without instruction
