     Are you in the UK?They don't need winter heat, have you been watering it, spraying the leaves? Are you feeding it? Ours are in a frost free green house. Bubble wrapped, little tubular heater. Only the oranges are in the conservatory,they are much more tender. It's north facing,no sun in the winter in there, just the light, coming through the windows and roof.

    @Ian Durrands 966 hi, I usually give anything that has leaves turning yellow a tonic of sequestered iron and sea weed. It sounds as though you are letting it feel like summer in a warm conservatory. But if you have loads of fruit I wouldn’t disturb it as the fruits may fall off. Valerie

    lack of nitrogen?  They do need two different feeds thru the year - one with higher percentages of P & K plus magnesium and other trace minerals thru winter for healthy fruit and flowers and then one with a higher N percentage for healthy leaves thru summer.

    My citrus plants go into a polytunnel for winter with just the winter sun to warm them a bit, if at all.  I suspect yours have been so warm they're moving to summer mode and just need nitrogen tho some sequestered iron and dilute Epsom salts for magnesium - 15ml salts to 5litres of water and used as a foliar spray for a more instant effect.
