If your company has acquired another, it has purchased the shares in the other company.
As such this is not goodwill, just purchase of shares and no capital allowances are available.
If on the other hand you've acquired a business from say a sole trader or partnership for example, different matter and the capital allowances available will depend on the split of the acquisition between goodwill, fixtures/fittings, etc. In essense however, CA's not available on goodwill....I'd strongly recommend you speak to your accountant before completing the acquisition in case you need to make any tweaks to the purchase contract.
