  • Weekend or evening visits sometimes required
  • Heavy buckets and wet clothes
  • Client homes can smell or be untidy

UK-Specific Tips

  • Source test kits and dechlorinator from branches of Maidenhead Aquatics for trade pricing once you hold a simple business card.
  • Check local council rules on carrying live fish in a vehicle.
  • Keep receipts for fuel and equipment; HMRC allows flat-rate deductions for van or car use.
  • Target postcodes with larger detached houses first; they hold bigger tanks.

FAQ

Do I need qualifications?

No formal certificate exists. Clients care that their fish stay alive after three visits.

Can I start with marine tanks?

Begin with freshwater only. Marine systems demand more expensive test kits and carry higher livestock risk.

How do I handle a client who cancels?

Require one month’s notice in writing and keep a short waiting list of other tanks.

Is insurance worth it?

Public liability cover costs under £15 a month and protects against claims if a tank leaks during a service.

Conclusion

Steady monthly visits build faster than most side services once the first ten clients are booked. browse more ideas on MicroBiz365.
