Hiring someone to work on your home shouldn’t feel like a gamble. Whether it’s a simple repair or a full renovation, you want to know the person turning up at your door is qualified, trustworthy, and legitimate. The good news is that you don’t need to be technical, experienced, or industry-savvy to check a tradesperson’s credentials. You just need to know what to look for — and where to look.
This guide walks you through the essential checks every homeowner should make before hiring a tradesperson, in a way that’s simple, practical, and easy to follow.
1. Start With Their Business Identity
Before anything else, confirm the basics:
Their full trading name
Their business address (even if they work from home)
A working phone number
A professional email address
A website or profile that looks maintained
A legitimate tradesperson won’t hesitate to provide these details. If anything feels vague, inconsistent, or evasive, treat it as a warning sign.
2. Check Their Experience and Specialism
Not all tradespeople do the same thing — even within the same trade.
A “builder” might specialise in extensions, while another focuses on structural repairs. A “plumber” might be brilliant with bathrooms but not qualified for gas work.
Look for:
A clear description of what they specialise in
Examples of similar jobs they’ve completed
Photos of recent work
How long they’ve been in the trade
Experience in your type of job matters more than general experience.
3. Look for Verified Reviews (Not Just Testimonials)
Reviews are one of the strongest indicators of reliability — but only if they’re genuine.
Here’s what to look for:
Reviews collected through a trusted platform
A mix of recent and older reviews
Consistent patterns (punctuality, communication, quality)
Photos attached to reviews
Responses from the tradesperson
Be cautious of:
Reviews only on their own website
Dozens of reviews posted on the same day
Reviews that all sound identical
Verified reviews give you a far clearer picture of what to expect.
4. Confirm Their Qualifications and Certifications
Some trades legally require qualifications. Others don’t — but qualifications still matter.
Here’s a quick breakdown:
Gas work
Must be Gas Safe registered.
Electrical work
Look for NICEIC, NAPIT, or similar accreditation.
Plumbing, heating, boilers
Look for relevant certifications or manufacturer training.
Roofing, carpentry, decorating, general building
These don’t have mandatory qualifications, but training, apprenticeships, and experience still count.
A good tradesperson will happily explain what they’re qualified to do.
5. Ask About Insurance (This One’s Crucial)
Every tradesperson should have:
Public liability insurance
Employer’s liability insurance (if they have staff)
Guarantees or warranties on their work
If they can’t provide proof, walk away. Insurance protects you if something goes wrong.
6. Check Their Portfolio or Gallery
A portfolio tells you more than any certificate ever could.
Look for:
If they don’t have photos, ask why. Most good tradespeople document their work.
7. Look for Professionalism in Communication
You can tell a lot from how someone communicates:
Do they reply promptly
Do they answer questions clearly
Do they provide written quotes
Do they explain things in a way you understand
Do they seem organised
Professionalism is a strong predictor of reliability.
8. Ask About Their Process
A trustworthy tradesperson will explain:
How they approach the job
What materials they use
How long it will take
What could affect the price
How they handle unexpected issues
How payment works
If they can’t explain their process clearly, they may not have one.
9. Trust Your Instincts
Credentials matter — but so does your gut feeling.
If something feels off:
The quote is suspiciously cheap
They pressure you to decide quickly
They avoid giving written details
They can’t explain their experience
They dodge questions
…then it’s better to keep looking.
10. Use a Trusted Directory to Do the Hard Work for You
The easiest way to check credentials is to use a platform that:
Verifies identity
Collects genuine reviews
Displays qualifications
Shows photos of real work
Lists experience and specialisms
Filters by location
Helps you compare options
It saves you time, reduces risk, and gives you confidence before you even make contact.
Final Thoughts
Checking a tradesperson’s credentials doesn’t have to be complicated. With a few simple steps — verifying identity, reviewing experience, checking qualifications, confirming insurance, and looking at real customer feedback — you can hire with confidence.
A little due diligence upfront can save you money, stress, and disappointment later.
