Hello, this is Jim and I am a dual-qualified lawyer (UK and Republic of Ireland) and happy to help you this evening.
The notice of proposed allocation to fast track will mean that your case will be allocated to the fast track - unless there is a reason why it shouldn't be allocated (e.g. if it is more complicated). The value of £13K means it will likely stay in the fast track due to the value being between £10,000 and £25,000.
You will need draft directions which I attach. You must send the completed DQ and daft directions to the court by 16th December (so post it well before to ensure it gets there). And a copy to the other side too.
You need no supporting documentation at this stage - that comes later with disclosure and exchange of witness evidence. The issues in this case are simple and concerns a consumer dispute, so the Fast Track is where this case will be for sure.
The evidence you have is enough to establish breach of contract under the Consumer Rights Act 2015. You should incorporate your evidence in to a formal witness statement (you will note from the draft directions that there will be a date in future where you have to exchange witness evidence with the other side). This is your chance to have your say on paper. If there is a final hearing you will be asked about the contents on the statement and cross examined (if the other side employs a barrister and likewise if you do the same, you can cross examine your opponent on the contents of their evidence).
Once the court has reviewed your directions questionnaire (and your opponent's) it will make an order for directions - I attach an N265 form which is needed for standard disclosure. And a template statement for you to use to save you the time of finding one online.
