If you do intend to move the money into a MMF make sure it is a Short Term Money Market Fund. 

Short Term Money Market Fund: 
These money market funds are investment vehicles designed for short-term cash management needs, offering a low level of risk and high liquidity.

Here are three to consider:
Royal London Short Term Money Market Accumulation Fund
Vanguard Sterling Short-Term Money Market Fund.
Fidelity Cash Fund

+1 for this. The phrase "short term" is very important.
