Nest not controlling central heating

[Jmwblues]

I have had a google nest for 18 months. It was installed at the same tome as a new baxi system boiler and hot water cylinder.

My central heating comes on randomly when the nest says it is off. When this does happen the nest cant switch the boiler off and we just have to wait until it decides to switch off.

any help/advice would be appreciated
