Yes, it would be included insofar as your data rights are concerned, assuming it refers to you personally which I presume it does. If you had to sue the landlord, the court would actually tell you both to make full disclosure - which would include the inspection report.
In the meantime you should make a Subject Access Request (SAR) and give them one month to respond.
Here is a useful link for a GDPR request:
If they do not respond, this is in breach of the General Data Protection Regulations (GDPR).
GDPR protects data subjects. What this means is that the Information Commissioner's Office (the "ICO") can levy large fines if they find there has been a breach. The fines are either up to £17m or 4% of company turnover, whichever is greater. As such, assuming the SAR is ignored, I would recommend that you inform the ICO on 0303(###) ###-#### They also have a "live chat" facility on their site - you can visit it here: https://ico.org.uk/make-a-complaint/
They will take your details and if they feel there has been a data breach will contact the company. A lot of companies do not realise the extent of the fines and it is envisaged a lot of businesses will go bust in the event of a breach, not just because of the fines but because the aggrieved party can also claim compensation.
I have also attached a useful template letter you may wish to use if the deposit scheme does not result in a refund.
