## Before you hire a builder
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
- Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
- Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work — and that they are current.
