Before committing to any garden room installation project, follow these essential tips to protect yourself and ensure a successful outcome.
Get Multiple Quotes
Always obtain at least 3 written quotes from different contractors. Compare not just prices, but what's included, timelines, and payment terms. Be wary of quotes significantly lower than others.
Check Credentials
Verify the trader is legitimate. Ask for proof of insurance (public liability and employer's liability), relevant trade certifications, and check if they're registered with trade bodies like TrustMark, FMB, or NICEIC.
Review Past Work
Request references from previous customers and photos of completed projects. Check online reviews on Google, Checkatrade, or Trustpilot. A reputable trader will be happy to share their track record.
Get Everything in Writing
Insist on a detailed written contract covering the full scope of work, materials to be used, start and completion dates, total cost, and payment schedule. Never rely on verbal agreements alone.
Be Careful with Deposits
Never pay the full amount upfront. A reasonable deposit is typically 10-25% to cover initial materials. Pay the balance only upon satisfactory completion. Avoid cash payments where possible.
Understand Your Rights
Under the Consumer Rights Act 2015, work must be carried out with reasonable care and skill. If things go wrong, you have the right to request a repair, price reduction, or refund.
Agree Clear Timelines
Establish a realistic project timeline with key milestones. Include clauses for delays and ensure you're informed of any changes. Good communication throughout prevents misunderstandings.
Check Planning Requirements
For major works, confirm whether planning permission or building regulations approval is needed. The contractor should advise, but ultimately it's your responsibility as the homeowner.
