What it is
A small team with a mid-sized excavator (often 5 to 8 tonnes), a tipper or grab lorry and hand tools. You dig foundations, lay drainage, prepare site areas and do base work for extensions, outbuildings and small developments.
Your first three steps
- Gain site experience and the plant competence cards that most sites and contractors expect (such as CPCS or NPORS) if you don't already have them, and decide whether to buy, finance or hire the machine at first
- Set up as a sole trader or limited company, arrange plant, public liability and employer's liability insurance, and sort out the Construction Industry Scheme
- Approach local builders and developers for sub-contract work, and build a few references and photos of finished jobs
Who pays
Builders, developers, self-build clients, housing contractors and utility sub-contractors.
How it makes money
Quoted prices per job or per stage of a build, or day rates as a sub-contractor. Carting away spoil and supplying aggregates can add to each job.
Skills that help
- Experienced machine operation and site safety
- Pricing and managing jobs
- Leading a small team
- Working with builders, engineers and building control
Watch out for
- No general licence is needed to do groundworks, but main contractors usually expect valid plant and site safety cards (such as CPCS, NPORS or CSCS)
- If you carry soil or rubble away from sites, check whether you must register as a waste carrier with the Environment Agency (or SEPA or Natural Resources Wales) and keep waste transfer notes
- If you run a tipper or grab lorry over 3.5 tonnes, check with the Traffic Commissioner and DVSA whether you need an operator licence, and make sure drivers hold the right licence category
- Employer's liability insurance is needed once you take on staff, plus public liability and plant cover
- Risk of striking buried services, so check HSE guidance and use service plans and scanning equipment
- Check rules on red diesel use, which have changed in recent years
- Machine finance, fuel and repairs can strain cash flow if payments from builders are late
- Check your health and safety duties on site, including CDM responsibilities

Do I need a licence to do groundworks and excavation?
