What it is

A small team that looks after the heating, ventilation and plumbing in other people's buildings: planned servicing, safety checks, repairs and replacement installs. The aim is ongoing contracts rather than one-off jobs.

Your first three steps

  1. Make a list of local letting agents and managing agents and ask what they look for in a maintenance contractor
  2. Check which accreditations or approved contractor schemes your target clients ask for, and get a simple job and certificate system in place
  3. Offer a tidy fixed-price service package to a few agents as a trial, then ask for a longer contract
Who pays

Letting agents, landlords with several properties, managing agents, small businesses, schools, care homes and housing groups.

How it makes money

Annual or monthly service contracts, call-out and repair charges, and quoted installs when equipment needs replacing.
