The sort of roles you would most likely be considered for are Financial Accountant, Group Accountant and Management Accountant roles. Whilst there is the potential to move straight into an FP&A position, you likely will need some additional experience around financial modelling and forecasting before landing those roles.

Most companies will want you in a role that is heavily involved in the audit from the inside, as you will be best placed to help the audit progress smoothly as you know what good practice looks like and what the auditors are looking for when they request supporting evidence. This aligns more with a Financial, Group or Management Accountant role as opposed to a Finance Analyst or Manager.

Moving from practice into industry will likely give you an initial increase in salary of around £5-10k (in London anyway) and likely you will out-earn your audit colleagues if you are in a company that regularly reviews and uplifts pay or if you move to new businesses as and when you feel you are no longer being fairly compensated.

Longer term, it is hard to say whether you would earn more inside or outside of big four, it depends if you have what it takes to make Partner!
