Do you mean your employer - the company you work for?
I have seen these schemes in action and have two views. Firstly, if you don`t know anything much about computers take advice before you choose one. The scheme may be run by an outside company and you should check the small print very carefully. What happens if scenarios - you move companies, you are made redundant etc.
Anyway, In general the schemes offer tax savings and are rather like leasing something over two or three years. Usually you can buy the product for a nomonal fee at the end of the agreement. The knowledge that the payments are deducted net of tax on a monthly basis make it an easy choice if you don`t have cash around. It also gives you home access to a computer and the benefit to the employer is that you will become computer literate fairly quickly and might even take work home to complete.
However, the last scheme I saw was run by Dell for a large Rail Company. When I checked the prices of the models offered against their current website offers they were horrendously expensive. About 40% more expensive on the system he fancied even allowing for the tax savings. I`m afraid that computer prices have tumbled over the last year and the leaflet was 6 months old - I think they will continue to do so. Check the prices - it may be cheaper to buy outright or on a credit card.
Having said all that my mate bought one anyway - just for the convenience!
