How to Find a Good Plumber: 12 Questions to Ask Before Hiring

Why Choosing the Right Plumber Matters

A good plumber solves your problem quickly and fairly. A bad one can leave you with a bigger mess, unexpected bills, or even dangerous work. Here's how to find a plumber you can trust.

12 Questions to Ask Before Hiring

1. Are you Gas Safe registered?

If the job involves any gas work (boilers, gas cookers, gas fires), the plumber MUST be Gas Safe registered. This is a legal requirement. Ask for their registration number and verify it at GasSafeRegister.co.uk.

2. How long have you been trading?

Experience matters in plumbing. Look for plumbers with at least a few years of experience. Established businesses are more likely to still be around if issues arise later.

3. Do you have insurance?

A professional plumber should have:

• Public liability insurance - Covers damage to your property
• Professional indemnity - Covers faulty workmanship

Ask to see certificates. My Home Heroes carries £2M public liability insurance.

4. Can you provide references or reviews?

Check Google Reviews, Checkatrade, or ask for references from recent jobs. Be wary of plumbers with no online presence or reviews.

5. Will you provide a written quote?

Always get a written quote before work begins. It should include:

• Detailed description of work
• Cost of labour
• Cost of parts/materials
• VAT (if applicable)
• Estimated timeframe
• Any potential additional costs

6. Is your price fixed or estimated?

Understand whether you're getting:

• Fixed price - You pay what's quoted, regardless of time taken
• Estimate - May change based on actual work
• Hourly rate - You pay for time plus materials

For predictable jobs, fixed pricing gives you certainty.

7. Do you charge a call-out fee?

Some plumbers charge just to come and look. Others (like My Home Heroes) don't charge call-out fees - you only pay for work done.

8. What's your availability?

Can they come when you need them? Do they offer emergency call-outs? What are their working hours?

9. Do you guarantee your work?

Professional plumbers should guarantee their workmanship. Ask how long the guarantee lasts and what it covers.

10. Will you provide an invoice?

Legitimate businesses provide proper invoices. This is important for your records, any warranty claims, and if you need to claim on insurance.

11. What qualifications do you have?

While general plumbing doesn't require specific qualifications, look for:

• NVQ/City & Guilds in plumbing
• Gas Safe registration (for gas work)
• Manufacturer certifications (for specific boiler brands)

12. How do you handle unexpected issues?

Good plumbers will stop and discuss any additional work with you before proceeding, including the cost. They won't just do extra work and surprise you with the bill.
