I keep most of my honey in plastic (food) buckets and they go solid v quickly, as I have got a lot of rape in mine. I use a german "WECK Topf", which is a really useful piece of kit to have for all sorts of tasks. Ascott sells one too. Put the bucket in , fill up with cold water, put temperature on for 50 Deg C and a day or so later, honey is liquid and can be put into jars, that then are stored on top of the boiler (warmest place in our house, as OH veto-ed an AGA when we built). Also useful for bottling fruit, melting wax, making cheese.... etc etc
If your honey goes solid its a good sign for its quality, most supermarket honey stays liquid, because it has been overcooked and the sugars have changed, so no crystallisation. Would buy local though....
