Why this works in London
Demand in London is strong, and the work is a fair share of repeat work. Setting up is a bit of work, and you could be paid for your first job within a few weeks.
Where the first customers come from
- Trade referrals
- Farm and agricultural merchant noticeboards
- Google Business Profile
- WhatsApp Business
- Local Facebook groups
- Nextdoor
- Gumtree
Before you take on work
- Public liability insurance
- Hot work procedures and a fire watch after cutting or welding
