Cuts to Cabinet Office funding could hit the Office for Civil Society by around £11m a year, but the Charity Commission is still waiting to find out how much its budget will be cut, according to HM Treasury announcements.

HM Treasury has agreed deals on funding cuts with a number of government departments, including a 21 per cent cut at the Cabinet Office, the parent department of the Office for Civil Society.

These deals have been agreed in advance of the Autumn Statement and Spending Review, which will be given by George Osborne, the Chancellor of the Exchequer, on 25 November.

If the Cabinet Office funding cut was applied evenly across the department it would cut the Office for Civil Society budget to £45m in the year ending March 2020, from a proposed £56m in the current year.

In practice OCS spending has been considerably larger than the funding allocated at the last spending review, because it has included funding for the National Citizen Service, which cost £130m last year, and was not included in the OCS budget projections.

The OCS has seen a series of budget cuts over the last decade, from almost £230m a year under Labour.

Commission still waiting on budget decisions

The Charity Commission is also potentially in line for a significant budget cut, but Treasury sources said it has not yet been told whether it will face a drop in funding.

Potential to the Commission have already led the regulator to seek alternative sources of funding, including a levy on the charity sector.

William Shawcross, chair of the regulator, warned earlier this month that his organisation would not be able to do its job if it faced further cuts in funding.
