Forgive me if this is the wrong place to post, and the upcoming long post, I will try and keep it as concise as I can.

Due to being hospitalised for three months almost 2 years ago and my recovery to "normality" has been long and slow, my car has been sat in my garage all that time and never moved and off the road for both tax and insurance, Ironically I bought it brand new just a few weeks before everything went to pot,

My recovery to my new normal state has meant that although now that I am in a better state to drive, I am unable to use the brake with my right foot as I cannot lift high enough from the accelerator. After a driving assessment a few weeks ago it was agreed that I could drive again with a push control in place of the brake. My driving licence is currently being coded to enable me to go ahead with the modification.

So now to the point of this post. I am struggling to work out what order I should do the following - tax, insurance, repair/service car and modification. I was under the impression you cannot insure car without it being taxed but also cannot tax car without insurance? I also know that you have to declare modification to insurance company, but if I insure car before getting the adaptation (which I would assume I would need to to keep it legal) then do I inform about modification at the beginning or a second time when the modification has been done? Every time I try to work this out I seem to go round in circles. And of course as I cannot drive my car even when insured and taxed until it has been modified I cant drive it to a garage.

I did contact a garage in a nearby town for advice to do the service and modification (which they specialise in in addition to services and repairs) but told me to seek advice from friends and family???? It doesnt help I am deaf and do everything online.

Sorry for the long post and I hope this all makes sense. Hoping someone can give me some starting points to help or guide me to somewhere else. Thank you for reading :)
