Rydym ni’n uwchraddio ein gwefan ar hyn o bryd. Efallai y byddwch yn sylwi bod rhai adrannau yn edrych yn wahanol tra byddwn yn gwneud y gwaith hwn. Ni fydd y cyfleuster chwilio hefyd ar gael yn ystod yr amser yma.

I haven’t received any the letters or notices from the regulator, but you have the correct address.

If the letters or notices have been sent to the correct address, and we haven’t received any returned post, we treat it as correctly served and received by the person it has been sent to. If you are experiencing difficulties with your post, you will need to contact the Post Office.

If you wish to contact us directly you can do so by visiting our contact us page, please ensure that you have the employer’s PAYE reference or letter code to hand before you call or email us.
