Take an unimpressive FTSE100 internship?

Hi all, I hoped to get some advice on something. I've been offered an internship at Taylor Wimpey (UK's biggest house builder, FTSE100), but it's in health and safety (the job description makes it sound pretty unimpressive) I'm unsure whether it will improve my CV for strategy consulting purposes, but I've heard MBB etc prefer big name employers. The alternative is probably staying on at the CSR consultancy I currently work for: we have some well-known clients, but there's not much room for promotion/new responsibilities in the company. Any advice you have would be appreciated.

By the way, I'm based in the UK and planning to apply for graduate roles there in September.
