Try repotting it in fresh compost and, probably, a slightly larger pot. These are naturally shade loving, hence their use in houses, so make sure that it is not in too strong a light. Alternatively, you may have it in too much shade!! So, depending on site, move it towards or away from the light! Sorry to be a bit contradictory!

Its in a large pot in our conservatory so its may be with all the sun.

I shall check the roots .

Many thanks

Mine always used to go pale when they needed water.

I have spit them up out of large pot and gave a good feed with miricale grow.
