Hiya, I've just bought a kentia palm and have noticed the roots are slightly above the soil? should the plant be deeper into the soil?
This is how the palm will grow naturally. There is no need to cover them. When you decide to re pot, then you can cover them slightly, but the will come up again later. Just make sure not to bury it more than an inch or so passed the original level.

Have had problems with aphids residing on the underside of leaves of my Kentia and have treated the plant with diluted dish washing liquid spray which seems to have done the trick in removing them. However, the Palm is not doing well, the leaves are generally browning and look distinctly unhealthy. I did repot the palm about 6 weeks ago and felt that the palm was becoming pot bound so trimmed some roots away, that could have been a serious mistake given its appearance now.
This has undergone some very harsh treatments. There is a chance that it will recover, but trimming the roots on these is never recommended. They will prefer being rootbound.
The dish soap works on many plants, but also many plants are sensitive to this treatment. This would be one of them. I recommend neem oil for aphids. Alternatively, you can slice and boil hot peppers in water. Let this cool, strain, and spray. This is a much more gentle, and effective treatment.
Unfortunately, there is very high chance that this plant will be on its way out now. If you are very careful, and give it absolute perfect care, then there is still a chance for it.

Many thanks for your answer and advice. I'll give it some tender loving care over the next days and weeks and see if I can bring it back from the brink...........
I have noticed my Kentia Palm with curling leaves. Is there something I need to do.
These palms are susceptible to many diseases, physiological problems and insect attacks. When their leaves curl, there are two possible causes.
Thrips are tiny insects with fringe on their wings that feed on the cat palm’s plant cells. They cause stippling or tiny spots on the leaves, silvery scars, calloused spots and stunt the leaf, causing it to curl or roll.

Is that normal or how do I remedy?
Can you include a photo? This can be done by wind, or animals. The leaf can usually survive if snapped, so it doesn't really hurt the palm. To stop the issue, you will need to catch the pest in the act. Knowing what it is will help me to find a remedy to stop this.
My kentia palm leaves short and shorter?
This is completely normal. This actually looks good compared to many houseplant Kentia. I wouldn't worry about this. Here is an article for more information on care: https://www.gardeningknowhow.com/houseplants/kentia-palm/howea-forsteriana-kentia-palm.htm
I have 2 palms in the pagola and find that the fronds leave green oily residue on furniture and walls. What is causing it and how can I prevent it?
This sap is likely caused by scale on the palm. This article will give you information on how to control this: https://www.gardeningknowhow.com/houseplants/palms/sticky-palm-tree-leaves-treatment-for-palm-scale.htm
I potted a Kentia Palm a few weeks ago & it is on a west facing balcony. The leaves are turning brown & I wonder if I have over-watered it, or if I put too much Dynamic Lifter organic fertiliser in the potting mix. I lower a blind which is like shade cloth on hot days.
This could definitely be fertilizer burn. This would be the typical symptom. If your container has drainage holes, you can water a gallon of water through. If not, then you will just have to hope the nutrients run their course before the palm dies.
You should only water this when it is almost completely dry.
