What it is

You run your own small installation business. You survey and quote jobs, order made-to-measure frames from a supplier, fit them and handle the paperwork and aftercare.

Your first three steps

  1. Open trade accounts with a few local or online uPVC fabricators and compare lead times and prices
  2. Look into competent person scheme membership and get public liability insurance and a simple guarantee process
  3. Quote for friends, neighbours and local landlords, and collect photos and reviews of finished jobs
Who pays

Homeowners, landlords, letting agents and property managers.

How it makes money

You charge a job price that covers materials, fitting and a margin. Repeat work and referrals from landlords and agents help keep the diary full.
