Buyer Guide: How to Hire a Tradesperson You Can Trust

Most bad trades experiences do not happen because a homeowner made an unreasonable decision — they happen because nobody checked a few basic things before work started. This guide covers the habits that consistently separate a smooth, fairly priced job from a costly, stressful one, whether you are hiring a plumber for a leak, an electrician for a rewire, or a builder for an extension.

Step 1 — Confirm Qualifications and Insurance

For gas work, only a Gas Safe registered engineer may legally carry it out — always check the register directly rather than taking a business card's word for it. For electrical work, look for NICEIC, NAPIT or a similarly recognised registration. For any trade, ask to see public liability insurance before work starts, not after something goes wrong.

Step 2 — Get More Than One Written Quote

A single quote gives you no baseline for whether a price is reasonable. Getting two or three written quotes for anything beyond a small repair lets you compare not just price but how clearly each tradesperson explains the scope of work — a vague quote is often a warning sign in itself.

Questions Worth Asking Before You Hire

• Are you registered with the relevant body for this type of work, and can I check that directly?
• Does the quote separate labour, materials and any contingency for unexpected issues?
• What happens if the job uncovers a problem that was not visible beforehand?
• Can I see photos or references from similar, recent jobs?
• What is the expected timeline, and how will I be told if it changes?

Red Flags to Watch For

• Pressure to decide immediately, or a discount that only applies "if you sign today"
• A refusal to provide a written quote, or a quote with no breakdown at all
• Reluctance to show proof of registration or insurance when asked directly
• Requests for full payment upfront before any work has started, especially for larger jobs
• No fixed address or verifiable business details, only a mobile number

DIY vs Calling a Professional

Some jobs are genuinely safe for a competent homeowner to attempt; others carry real legal and safety requirements. Gas and most electrical work sit firmly in the "call a professional" category in the UK, both for safety and because unqualified work can invalidate home insurance. Cosmetic and low-risk maintenance jobs are more often reasonable to consider doing yourself, provided you are honest about your own skill level.

Before You Hire — A Quick Checklist

• You have checked registration and insurance directly, not just taken it on trust
• You have at least two written, itemised quotes to compare
• You understand what happens if the job scope changes once work begins
• You have agreed a payment schedule tied to progress, not full payment upfront
• You have considered whether this is genuinely a DIY-safe job or one that needs a qualified professional
