The decision on depreciation is yours. As the director of the company it is your responsibility to decide how quickly those assets are likely to lose value and the depreciation policy should reflect that.
If you are looking to purchase assets from your company as part of the closure process then you would need to consider an approximate market value of those assets which may not be equal or even similar to the value declared in the accounts.
It may also be necessary to consider balancing charges when disposing of assets and any balancing charges would be calculated by reference to the WDV of the assets for capital gains purposes versus the value realised on disposal.
