Thermostat replacement

I need assistance with replacing a faulty heating thermostat at my property. The current model is Danfoss 087N791400 TP5000Si RF + RG1, which is no longer functioning properly and needs to be replaced.Additionally, one ring of the gas hob is not functioning properly and requires inspection and repair.I would appreciate it if you could review this job and provide a reasonable quote for both the labor and the required materials.
