“Sorry for the late reply” is natural and appropriate in most situations. You can adjust it to sound warmer, more formal, more accountable, or less apologetic depending on the delay and your relationship with the recipient.

Apologies for the delayed response
A polished professional option that works well in email and business correspondence.
Example: Apologies for the delayed response. I’ve now reviewed the proposal and added my comments.
Sorry for the delayed response
Slightly warmer and less formal than “apologies,” while still appropriate at work.
Example: Sorry for the delayed response—I wanted to check the figures before replying.
Thank you for your patience
Useful when the delay is already obvious and you want to acknowledge it without leading with an apology.
Example: Thank you for your patience. I can now confirm the revised delivery date.
Please excuse the delay
Formal and concise, especially suitable when the reply has taken noticeably longer than expected.
Example: Please excuse the delay in getting back to you.
Sorry it took me a while to reply
Friendly and conversational for colleagues, friends, or less formal professional relationships.
Example: Sorry it took me a while to reply. It’s been an unusually busy week.
Apologies for not getting back to you sooner
A clear, accountable phrase when you know a quicker response would have been preferable.
Example: Apologies for not getting back to you sooner. I’ve attached the information you requested.
Thank you for bearing with me
Warm and appreciative when the recipient has been waiting while you dealt with something.
Example: Thank you for bearing with me while I confirmed the details.
I’m sorry for keeping you waiting
Best when the delay directly inconvenienced the other person or held up a decision.
Example: I’m sorry for keeping you waiting. The approval has now come through.
Sorry for the slow reply
Informal and friendly, suitable for familiar colleagues or personal messages.
Example: Sorry for the slow reply—I’ve only just caught up with my messages.
Thank you for waiting for my response
A straightforward alternative that emphasizes appreciation rather than apology.
Example: Thank you for waiting for my response. I’m happy to proceed with the suggested date.
