Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if he will make an estimate of the number of people with wealth over £10 million in each of the past 10 years.

The tax information HMRC holds does not include comprehensive data on the wealth of taxpayers.

The Office for National Statistics undertakes a Wealth and Assets survey biennially, which can be found here: https://www.ons.gov.uk/peoplepopulationandcommunity/personalandhouseholdfinances/incomeandwealth/datasets/totalwealthwealthingreatbritain.

Table 2.5 provides a percentage of households estimated to have wealth of over £1 million. The most recent estimate was 17 per cent of households.
