What it is

A mobile service that checks, services and replaces portable fire extinguishers and fire blankets on customers' premises, and keeps records of each visit. You work from a van with a stock of extinguishers and spares.

Your first three steps

  1. Book a recognised extinguisher servicing training course and check what competence evidence customers and insurers expect
  2. Get quotes for public liability and professional indemnity insurance, and for a trade supplier account for stock and spares
  3. List 50 local businesses near you and offer a free check of their extinguisher labels and service dates
Who pays

Small businesses, landlords, letting agents, pubs, cafes, care homes, schools and community buildings.

How it makes money

Fixed price per extinguisher serviced, plus sales of new units, signage and replacements. Annual contracts bring repeat work and make a local round predictable.

Skills that help
  • Careful, methodical record keeping
  • Practical and safe with equipment
  • Reliable customer service and follow-up
Watch out for
  • Third-party certification (for example BAFE) is often asked for by larger customers and insurers, so check what your target customers require
  • Public liability and professional indemnity insurance; mistakes in fire safety work can have serious consequences
  • Rules on handling, refilling and disposing of extinguishers and waste, so check with the Environment Agency or your local equivalent
  • Fire safety legislation differs across England, Wales, Scotland and Northern Ireland, so check which applies to your customers
  • Heavy lifting and a vehicle carrying pressurised equipment, so check van insurance and safe loading
