What trademark class is a plumber in?

Most plumbers register in class 37. Class 37 covers construction & repair. You only ever register the classes that match what you actually sell.

Do plumbers need to register in more than one class?

Often, yes. A trademark is only protected in the classes you register, and you pay a fee for each one. Plumbers usually start with class 37, then add others as the business grows.

How much does it cost a plumber to register a trademark?

Filing direct with the UK IPO costs £205 for the first class and £60 for each additional class, so a plumber covering class 37 pays about £205. The fee isn't refunded if your mark is refused — which is why checking the name is free first matters.

Plumbing, installation and repair work sits in the construction-and-repair class, the home of building trades. Plumbers who also sell boilers, taps or bathroom fittings add the goods class that covers sanitary and heating equipment.

Before you file in class 37, make sure the name is free. If it's already taken, your application can be refused — and the £205 IPO fee isn't refunded. Checking takes seconds and costs nothing.
