Ask These

Questions to ask

Credentials & insurance

  • Are you insured? Can I see your public liability cover?
  • Are you registered with the relevant body (e.g. Safe Electric, RGI)?
  • Can I see examples of similar work or speak to recent customers?
  • Who exactly will be doing the work — you or subcontractors?

The quote & scope

  • Is this quote fixed or an estimate, and does it include VAT?
  • What exactly is and isn't included?
  • Who supplies the materials, and what quality/brand?
  • What happens — and what's the cost — if extra work is needed?

Timing

  • When can you start and how long will it take?
  • Will you be on this job full-time or juggling others?
  • How will you handle delays or bad weather?

Payment

  • What deposit do you need, and what are the payment stages?
  • How and when is the final payment due?
  • Will I get a receipt and a VAT invoice?

After the job

  • What guarantee or warranty do you offer on the work?
  • Will I get certificates or compliance documents where needed?
  • How do we handle any snags after completion?

Trust the answers, not just the price

How clearly and confidently a trade answers these questions tells you as much as the number at the bottom of the quote.

FAQ

Frequently asked questions

What's the most important question to ask?+
Whether they're insured and registered, and to see proof. It protects you if anything goes wrong and filters out the cowboys immediately.
Should I always ask for a written quote?+
Yes. A written, itemised quote stating what's included and whether it covers VAT is essential for comparing fairly and avoiding disputes.
What if extra work is discovered mid-job?+
Agree in advance how variations are priced and approved, so unexpected work doesn't lead to a surprise bill.
Should I ask about guarantees?+
Always. Ask what warranty covers the work and whether you'll receive any certificates or compliance documents.
