When a house is part of the asset for a debt, is it possible to sell it before the OR forces the sale , to ensure a fair price and more money towards the debt? And secondly, in a joint ownership, if the wife is not involved in the debt is she allowed to keep her share of the house and what percentage would that be?
You will have to speak to the OR obviously, to tell them of your intentions as there will no doubt be a restriction lodged at Land Registry.
Hopefully Lisa Thomas will be along to help but I would suggest you speak to a solicitor for some advice.

If so then yes you can agree with the Official receiver/Trustee to voluntarily sell the property rather than go through the stress and hassle and costs of a forced repossession.
Your wife will receive her share of interest from the net proceeds.
Most joint properties are assumed 50:50 ownership unless you can prove otherwise.
