I've moved this post to the Expat Tax section, where I think it will attract more interest. Your question applies to more than just the British residents.
Simply put, you CANNOT deduct National Insurance Contributions on your US tax return - except for the portion that is related to health insurance, and then only if you meet the requirements for deducting health insurance on Schedule A (i.e. your deductible health care costs, including insurance, are more than 7.5% of your AGI).
All other deductible taxes are taken on the "Other Taxes" part of Schedule A. But read the instructions carefully (both for Schedule A and in Pub 54). Social security taxes are specifically NOT deductible, and in any event, National Insurance contributions aren't considered "taxes" by the IRS.
It's also important to understand that, if you are taking the FEIE (form 2555 - exclusion for foreign earned income), your deductions from Schedule A have to be allocated between your earned income excluded from taxation and the rest of your income. Generally, if your earned income falls under the maximum amount you can exclude (i.e. about $92K), then you wouldn't bother to itemize your deductions.
Cheers,
