Anyone can submit an entry, as long as they or the firm/company they are entering meet the criteria for the relevant category. There is also only one entry per firm/company per award.

The time period covered by entries should be the 12-18 months prior to the entry deadline. With the exception of the International Law Firm Innovation Award, a substantial part of the initiative or project cited in the entry must relate to activity undertaken in the UK or by UK-based personnel.
Covering statement and evidence
Your 800 word statement is your entry. It must 'tell the story' while also seeking to cover the specific criteria as set out in each category.
The weakest part of many entries is often the failure to include clear evidence of achievement or explanation of why the achievement was significant or innovative. The judges will be harsh on entries that do not include clear statements of objectives and targets supported by evidence that these targets were reached. For example, if business growth is the target, achievement of it should be demonstrated in measurable terms.
All the information contained in the entries that is marked confidential will remain so, and will not be released without the permission of the entrant.
Supporting material
There is a strict limit of one piece of supporting material per entry. It is not obligatory to include supporting material - indeed it could count against you if the material is not pertinent to the entry. If you do include such material (which must be in digital form) please refer to it in your covering statement.
