Slocombes Neasden gone? how good is the replacement?

Does anyone know what happened to Slocombes motorcycles at Neasden?
I could not find any information about why/how they disappeared and there seems to be a new dealership, Omega Yamaha, where they were located.
I’m wondering if anyone tried the new dealership - particularly for servicing Yamaha bikes (I’ve had my MT-09 serviced with Slocombes for several years).
