Before you hire any tradesperson in the UK, check that they hold the correct trade registration for the work, carry public liability insurance, and can provide references from recent jobs. These three steps alone will filter out the majority of unqualified or rogue operators before any work begins.
Know Which Registrations Actually Matter
Not all trades are regulated in the same way, so the first thing to confirm is whether the work requires a specific legal registration.
- Gas engineers must by law appear on the Gas Safe Register. This is a legal requirement, not a preference. You can verify any engineer's registration on the Gas Safe Register website using their licence number.
- Electricians carrying out notifiable work, such as a new circuit or a consumer unit replacement, must be registered with a government-approved competent person scheme. The Registered Competent Person Electrical website lists approved schemes including NICEIC and NAPIT. A registered electrician can self-certify their work to building control, saving you a separate application.
- Plumbers should ideally be registered with WaterSafe, which lists plumbers competent to work on water supply systems.
- Builders and general contractors are not covered by a single mandatory scheme, but membership of the Federation of Master Builders (FMB) requires passing an independent inspection and holding public and employers' liability insurance.
- TrustMark is the only government-endorsed quality mark covering all trades in and around the home. Searching by postcode on the TrustMark website will return vetted local firms across dozens of trades.
For any work above ground level, whether a roofer, a window fitter or a painter on a scaffold, the tradesperson's work falls under the Work at Height Regulations 2005, enforced by the Health and Safety Executive (HSE). The regulations apply to any situation where a fall could cause personal injury, with no minimum height threshold. A legitimate contractor working at height should be able to demonstrate they have planned the work safely and are using appropriate equipment.
Verify Insurance Before Anyone Sets Foot on Site
A qualified tradesperson is not the same as a protected one. Always ask for evidence of public liability insurance before work starts. This covers damage to your property or injury to a third party caused by the tradesperson's work. For larger jobs involving employees or subcontractors, employers' liability insurance is also a legal requirement for the firm under the Employers' Liability (Compulsory Insurance) Act 1969.
Ask to see the current insurance certificate, note the expiry date, and check that the level of cover is appropriate for the scale of the job. Reputable firms will provide this without hesitation. A trader who cannot or will not produce a certificate is a firm red flag.
Get at Least Three Written Quotes and Compare Them Properly
A quote and an estimate are not the same thing. A quote is a fixed price that the tradesperson must honour unless you authorise additional work in writing. An estimate is an approximation that can change. Always ask for a written quote that sets out the scope of work, the materials to be used, the start date, the expected duration, and what happens if problems arise mid-job.
Getting three quotes allows you to spot outliers in either direction: an unusually low price may indicate underqualified labour or inferior materials, while an unexplained premium may not reflect extra quality at all. Confirm all figures directly with the firm, as rates vary by location, trade and the specific nature of the work.
Pre-Hire Checklist
Run through these points before signing anything or paying a deposit:
- Trade registration confirmed (Gas Safe, NICEIC, WaterSafe, FMB or equivalent)
- TrustMark or similar government-endorsed scheme membership verified
- Current public liability insurance certificate seen
- At least two references from recent, comparable jobs obtained and followed up
- Written quote received, not just a verbal estimate
- Scope of work, materials and start date all set out in writing
- Payment schedule agreed - avoid large upfront payments before any work is done
- Method for handling disputes and defects agreed in writing
Red Flags to Walk Away From
Certain patterns consistently indicate a trader who is either unqualified, unreliable, or operating dishonestly. Be cautious if a tradesperson:
- Knocks on your door unsolicited and pressures you to commit on the spot
- Offers only a mobile number and no verifiable business address
- Asks for a large cash payment in advance
- Cannot or will not show a registration number, insurance certificate or references
- Quotes verbally only and refuses to put anything in writing
Local Trading Standards teams operate approved trader schemes in many areas, such as the Kent Trading Standards Checked scheme and the Edinburgh Trusted Trader scheme backed by the City of Edinburgh Council and Police Scotland. Checking whether a trader appears on your local council's approved list adds a further layer of assurance at no cost to you.
