BEFORE YOU BOOK

Check before you book

No register applies

No licence or register covers aquarium maintenance in England, Wales, Scotland or Northern Ireland. Fish are animals under welfare law, so the technician must care for them properly while working on the tank.

Ask about experience with your type of tank — freshwater, tropical or reef. legislation.gov.uk →

Insurance for water damage

No law requires an aquarium technician to be insured, but a leak or a dropped tank lid can do real damage. Ask about public liability insurance that covers your home.

Ask for the insurer and the cover.

Animal welfare law

An aquarium maintenance technician takes on a legal duty, not just a job. Under the Animal Welfare Act 2006 (England and Wales) a person in charge of an animal on a temporary basis is responsible for meeting its needs — diet, environment, protection from pain and disease — with equivalent duties in Scotland and Northern Ireland.

Ask how they would spot illness in your fish and what they would do. legislation.gov.uk →

VAT

Servicing an aquarium is standard-rated: 20% VAT applies to the visit, the water change and the filter media used. Over the £90,000 registration threshold a trader has to charge VAT and show it separately, next to its VAT number.

Ask for the VAT number, and whether the price per tank visit is quoted before or after the 20%. gov.uk →
