What it is

Offering sanding and finishing as a subcontractor, so other trades bring you the work. You use a smaller kit set up to begin with, and add more equipment as you earn.

Your first three steps

  1. Get hands-on training or shadow a working floor sander to build skills and contacts
  2. Contact local builders, joiners and flooring firms to say you are available for sanding work
  3. Start with hired or second-hand equipment on a few jobs before buying your own kit
Who pays

Builders, property developers, flooring companies, carpenters and letting agents who want a reliable sander without employing one.

How it makes money

Usually a day rate or an agreed price per job or per square metre. Repeat work from a few trade contacts can keep your diary steady with less marketing.

Skills that help
  • Basic sanding experience or willingness to train
  • Reliability and turning up on time
  • Working to a contractor's schedule
  • Building trade relationships
Watch out for
  • Public liability insurance, as contractors often ask to see proof before giving work
  • Check your tax status, as HMRC may treat you differently if you work only for one firm, and check whether the Construction Industry Scheme applies
  • Dust control and safety rules on shared building sites
  • Late payment from contractors, so agree terms and keep written confirmation of the work
