Problems paying

If you’re having trouble paying your Council Tax, it is very important that you let us know to see if there is anything we can do to help.

  • Phone: (01286) 682700 between 9:00am and 5:00pm Monday to Friday
  • Email: trethcyngor@gwynedd.llyw.cymru
  • Postal address (all areas): Revenue Unit, Council Offices, Stryd y Jêl, Caernarfon, LL55 1SH

Help available

We deal with each case individually so it is difficult to give details of the help that may be considered. It may be that a special payment arrangement can be offered, or advice about various discounts and exemptions.
