Change of passport used during naturalisation process

[Nikitas10]

Hello all,
first I'd like to thank you for a very information blog. I am Greek, studied in the UK and I have been living and working here for many years. I applied to get a British citizenship last August and as far as I know my application is still processed.
In the meantime, the passport I used for my application is about to expire. I assume I need to contact the HO. Do you think that will cause an issue or delay? Do you know who I should contact? Should I wait to get my new passport number before contacting them?
I am also going to change jobs in February. Do I need to let them know about that too? Should I wait till February for this?
Thank you for the reply, much appreciated.

Last August implies you applied in August -2014. That is a long time their normal SLA is 6 months. I would contact HO first and check what's happening with your application...

Any change of circumstance should be reported to the HO.

No sorry. I meant August 2015.
