Construction Experts

Selecting the right contractor is perhaps the most important decision you'll make for your construction project. With London's busy construction market and unfortunately some unreliable operators, it's crucial to know how to identify trustworthy professionals who will deliver quality work on time and on budget. This guide provides essential advice for finding and vetting contractors.

Essential Documentation to Verify

Before hiring any contractor, verify they have the following essential documentation:

Public liability insurance: Minimum £2 million (£5 million for larger projects)
Employer's liability insurance: Required if they have employees
Registered business address and company number
VAT registration (if turnover exceeds threshold)
Trade body memberships: FMB, NFRC, TrustMark, Checkatrade
Relevant qualifications and certifications
Health and safety policy documentation

Questions to Ask During Consultation

During your initial consultation, ask these important questions to assess the contractor's suitability:

Can you provide a detailed written quotation (not estimate)?
What is your expected timeline from start to completion?
Who will be the dedicated project manager for my job?
How do you handle variations and change requests?
What warranty do you offer on completed work?
Can I visit a current project or speak with recent clients?
How do you manage subcontractors?
What happens if you encounter unexpected issues?

Red Flags to Watch For

Be extremely cautious of contractors who display any of these warning signs:

Request large upfront payments (10-15% deposit is normal)
Cannot or will not provide references
Quotes significantly lower than other contractors
Pressure you to make quick decisions or sign immediately
Refuse to put agreements in writing
Have no fixed business address or only a mobile number
Cannot show examples of similar completed projects
Are vague about timelines or costs

The Importance of Written Contracts

Never proceed without a comprehensive written contract that includes:

Detailed scope of work with specifications
Total contract price and itemised costs
Payment schedule tied to milestones
Agreed start date and completion date
Specification of materials and brands to be used
Process for handling variations with pricing
Defects liability period and warranty terms
Dispute resolution procedure

Checking References and Reviews

Always verify a contractor's track record by contacting at least three recent clients. Ask specific questions about timekeeping, communication, quality of work, how problems were handled, and whether they would use the contractor again. Check online reviews on Google, Houzz, and Checkatrade, but be aware that some reviews can be fabricated. Look for consistent themes across multiple platforms.
