The annual salary for a UK MP is currently £65,738. This income is often topped-up with payments from other jobs; one-off consultancy projects, board member salaries, or media appearances. Using the Register of Members Interests raw data provided by the invaluable They Work For You, we can see how much extra they earn.

The graph above plots many of the individual payments we extracted data for, normalised by £/hour – how much the MP earned for each hour worked. The highest hourly wage goes to William Hague, at £7,331 per hour (£14,662 for a two hour talk).

You can see a clear plateau at £150/hour in the graph (click for a larger version), with slightly smaller £200/hour and £100/hour plateaus either side. The average rate was a little over £250/hour.

Although many of the tasks appear to be costed at a low hourly rate, it should be noted that we gave many MPs the benefit of the doubt: for those that recorded ‘1 day’ (rather than the standard number of hours), we assumed this was 24 hours, not a 7.5 hour working day.

Ten MPs managed to record a rate of £infinity/hour, by receiving payments for 0 hours worked: these include three payments of over £3,500 to John Gummer and three payments of £3,500 to Edward Leigh.

23 MPs managed to earn over £1000/hour, and 46 managed over £500/hour.

Of the top 10 highest paying items (in terms of £/hour) – each of which was between approximately £1500 and £7000 per hour – only Vince Cable, who appears twice on the list, donated his fee (in both cases) to charity. All other MPs – including William Hague, John Greenway, Michael Gove and John Gummer, appear to have retained their

payments.
