Equity is quite standard at startups as part of your compensation (granted options or RSUs as part of your total comp) but small companies on the other hand perhaps won't give any or will allow you to buy tiny amounts via some share scheme etc..
Ok thanks dowie.
It was discussed 6 months ago (I requested a 6 month review to gain clarity on my progression) and they said they'd like to ensure they know me well enough first which is understandable.
Be careful with things like RSUs as they are American and don't really work the same way in the UK. As a small company some form of tax advantaged share scheme, e.g. the Enterprise Management Incentive scheme is likely to be more what you're looking for. It gives the employer control over what you get and when you get it subject to certain conditions and locks in the income tax charge for you based on the value of the options at the date of grant.
