Most MEPs have an office in their constituency. Mine is in Birmingham, which is centrally located in my constituency of the West Midlands.
Parliament contributes an allowance of €4299 per month (about £3420) towards the costs of running this office. This is intended to cover rent, business rates, computers and other equipment, stationery, postage, communications expenses, phone bills and so on. This amount is not paid to me, but into a managed business bank account for which I am not the sole signatory. If there’s any surplus left over in this account at the end of my term in office, I’ll repay it to Parliament.
