I have received a reply today. Was not very helpful

. It seems a kind of general email that HO reply
Good Afternoon,
Thank you for your email
By way of background, naturalisation is not an automatic process and we have to make a number of enquiries before we can reach a decision on whether to grant citizenship.
The nature and extent of those enquiries, and the length of time taken to complete them, varies according to the particular circumstance of each application.
The progress of outstanding enquiries is regularly monitored with the agencies carrying out these enquiries on our behalf. It is only when we have the results of the enquiries that we can reach a decision on whether citizenship should be granted. We do not, ourselves, carry out these checks and we cannot, therefore, be sure how long they will take in each case.
I appreciate that UKVI website gives the following information in relation to waiting times for naturalisation applications:
"All applications for citizenship are subject to enquiries to ensure that the statutory requirements have been satisfied. Because of these enquires, we anticipate that applications may take up to six months to complete. Some applications may be dealt with more quickly and some may take longer, depending on the nature of the enquiries to be carried out".
As you will note, it is also made clear on the website that, in some cases, these enquiries may take longer than average to complete. You will appreciate the need to be careful and thorough in such matters.
These enquiries are still ongoing in regards to your application and we are sorry for the delay. As soon as the enquiries outstanding on your application are completed, we will ensure that an immediate decision is taken, and that you will be notified accordingly.
Kind regards,
UKVI
