You need to make sure you choose the right person for the job - someone you’re comfortable with fixing your issues. There are a few simple things to consider when choosing a plumber. Firstly, they need to be licensed, so don’t be afraid to ask for that information. All reputable plumbers will have this information available. Plumbers generally require a Gas Fitting License to work on gas appliances, so check this one too when getting in touch with them. Secondly, you’ll need to make sure they can handle the type of work you have. If you’ve got a specialised solar system installed at your home, they may need to know this beforehand so they will be equipped to fix your issue.
