It has been a litany of frustrations, my renewal was due for the 5th of December 2017:
Issue 1) In September I put in the paperwork now requested by the Police of your Doctor to prove your fitness to own guns a requirement required since 2016. A mark has to be put on your medical record and a form sent back by your Doctor to the Police stating no concern. One week after I put in the paperwork with the GP I registered with when I moved to Scotland phoned to say they were not going to process it as they didn't have my medical records from my previous practice in England. I then had to spend three months chasing my GP practice, my previous GP, Practice services in Aberdeen and tangentially CAPITA the company that has the contract to move records between England and Scotland. Eventually a week after I had to lodge my guns with an RFD in December as my certificates had run out a CD Rom arrives at my GP practice with my medical records on. On questioning the Firearms licensing office if the records can't be found they have no process for that and if a GP won't sign off ... no guns!
Issue 2) The CD Rom doesn't work on their computers. The secretary at the GP practice decides to ask my old GP to fax them a copy of my short record something they could have done three months earlier!
Issue 4) Another week passes whilst they wait for the fax.
Issue 5) Another week passes until the Doctor actually looks at it then I get the call asking for payment, £55 for this practice and they only accept cash as this GP practice appears to be run in the Dark Ages! Stellar service

Issue 6) This is the last few days before Christmas so the form doesn't get to the Police until the 28th of December for processing. Firearms office won't sort them until following week.
So today the certificates dropped on my doormat I open the envelope and my initial excitement drops like a lead brick thrown of a cliff....mistakes!
Mistake 1) More of a grievance really and I could live with it. The issue date for the new Certificates is the 6th of December 2017 making them in effect Four year and Eleven Month certificates. I can understand they can't exactly match the date to when it arrives but they could at least of marked them 3rd of January!
Mistake 2) Another that I could have rolled with. On my old certificate i had requested but never purchased Four moderators, I had decide to drop it down to one on my renewal and took care to explain to the FEO when she visited. Well I have four variable moderator slots on the new ticket! Not a big deal but a niggle.
Mistake 3) I requested .38 Special/.357 Magnum and they have put in the authorisation to purchase the rifle but missed out the authorisation to buy ammunition. So I can buy the rifle which I can stare at lovingly gathering dust in my cabinet but not shoot it!
Mistake 4) I requested 8 x 50r this time they have put in the authorisation to buy ammunition but missed the authorisation to purchase the rifle. So I can reload 100rds of 8x50r and stare lovingly at it gathering dust in my ammo safe but not buy the rifle to shoot it in!

So a phone call on Monday to the Licensing office, no doubt it will be the usual when THEY make mistakes send it back with a covering letter!
A side note about the £55 fee, whilst personally I don't have issue with paying a fee to your GP to do some work the amount paid is totally a result of the utter mess made by our representative organisations! There is no agreed fee or process to deal with these kinds of situations. In the end the BMA told their Doctors not to do it at all ... no money no work! BASC told its members not to pay anything! The NRA ... who knows?! The Police have there process and won't budge however Kafkaesque the situation can get as it is not their problem!
I have been holding off writing up this sorry story but at this point I wanted to put it up as a warning to fellow shooters!
If you move and change Doctor do not expect the medical records to arrive at your new GP, if a perfectly healthy person registers they will let the NHS trust know so they start getting the money they are due for another patient registered at their practice and send off for your old records. They will not lift a single finger to chase your records up if they don't arrive, the onus is on you to chase them or you could end up in the situation I did!
