Morning, hope you are as ok as possible. Sorry for slow reply.
You can download a copy of the scheme here📧
https://www.gov.uk/government/publications/criminal-injuries-compensation-scheme-2012
I have it bookmarked if easier, if you would like me to send you a copy just send me a message with your email address and I'll send it over.
So the scheme pays out if you satisfy all the eligibility criteria (making the application within 2 years of the assault, you have reported to and cooperated with the police, residency criteria, happened in the UK, you have no unspent convictions) and have suffered an injury set out in the tariff of injuries.
The tariff is a list of the injuries they compensate for and the set amounts for each. It starts at page 44 of the scheme.
For the injury to your nose, look at page 54. They deal with impact on smell and taste or both but not sure if that applies, and partial loss of the nose which would from the sounds of what you say. They will only compensate if at least 10% of your nose has been lost and then the amount is £2400.
You might also like to look at the section for facial scarring depending on how your injury is going to recover and look long term. Page 49 has a section for facial scarring and the scheme splits it between "significant disfigurement" (£2400) and "serious disfigurement" (£11,000).
Note if both apply (the loss and the scarring) you don't get both amounts added together, you get 100% of the highest and then 30% of the second. If there was a third tariff injury that would get 15% of that one.
If you have been impacted psychologically you may also be eligible for a payment for that. The CICA uses the phrase "disabling mental injury" for that aspect. See page 48 of the scheme. The psychological impact has to be disabling within their definition ("A mental injury is disabling if it has a substantial adverse effect on a person's ability to carry out mornal day-to-day activities for the time specified e.g. impaired work or school performance or effects on social relationships or sexual dysfunction"). They require a diagnosis and prognosis by a psychiatrist or a clinical psychologist. Very occasionally I have seen them make a payment on the basis of a counsellor/psychotherapist view where that person is supervised by a clin psych. The amount they pay for that depends on the duration of the symptoms.
If you have been off work for longer than 28 weeks as a result of the injury have a look at pags 11 and 12 about lost earnings. If you have "no or very limited capacity for paid work" as a result of the tariff injury then week 29 onwards they pay the current rate of SSP.
The scheme is not generous but often it is the only option and all we have.
I'd say you may as well make the application. If you have the information to hand it's is pretty easy to submit online (here - https://www.gov.uk/claim-compensation-criminal-injury/make-claim ) - you will need date and time of when it happened, report to police, police ref number etc.
Hope this helps but any queries, just give me a shout.
All the best for your recovery.
