You could do a college course in a subject like:
- Level 2 Certificate in Construction Plant Operations
- Level 3 Diploma in Construction and the Built Environment
These courses would teach you some of the skills needed for this work. You could then try to find a trainee job with a building company.
You'll usually need:
- 2 or more GCSEs at grades 9 to 3 (A* to D), or equivalent, for a level 2 course
- 4 or 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, for a level 3 course
