What it is
Small-scale groundworks such as digging foundations for extensions and garages, preparing bases for drives and patios, laying drainage runs and removing spoil, usually with a mini digger and a small tipper or trailer.
Your first three steps
- Get machine operator training (for example a CPCS or NPORS card) and a CSCS card if the sites you work on ask for one
- Price up a second-hand mini digger and trailer, and compare buying against hiring by the day
- Contact local builders, architects and landscapers and offer a free quote on their next small job
Who pays
Homeowners, small builders, landscapers and self-builders who need ground prepared before other trades arrive.
How it makes money
Fixed price per job or a day rate for you and the machine, plus charges for muck away, materials and skip or tipper hire.
Skills that help
- Safe operation of a mini digger
- Reading simple plans and setting levels
- Estimating and quoting jobs
- Physical fitness and reliability
Watch out for
- Public liability insurance with cover for plant, plus insurance for your own machinery and tools
- Check for buried services (gas, water, electric) before digging, and use cable avoidance tools and plans
- Waste carrying: if you take soil or rubble away in your own vehicle as part of your business, you will probably need to register as a waste carrier before trading. Check current rules with the Environment Agency in England, Natural Resources Wales, SEPA in Scotland or NIEA in Northern Ireland. Alternatively, use a registered carrier or a skip company, and always use a permitted tip or waste site
- Operator cards such as CPCS or NPORS are training and competence proof, not legal licences, but many sites and insurers expect them
- Towing a machine on a trailer may need a driving licence with the right category (for example B+E), depending on when you passed your test and the weights involved. Check your licence entitlement with DVLA
- Drainage and foundation work may need Building Regulations sign-off, check with your local council building control
