The charity is urging supporters to "give a gift that saves lives" by posting love notes in the windows of BHF shops in return for donations of £1 or £5. It has created a campaign website, www.bhf.org.uk/valentine, which features fundraising ideas and offers visitors the chance to donate an hour's worth of their salaries or buy virtual gifts.
Several corporate partners have produced themed merchandise for the campaign, including cookware firm Le Creuset, which has created a range of heart-shaped casserole dishes and accessories. The campaign will be backed by a direct mail drive to 200,000 warm donors in February.
The money raised will help fund BHF heart nurses and the charity's Heart Information Line.
RedR, the charity that trains and recruits international humanitarian aid workers, is encouraging its supporters to wear red clothing on 14 February and to make donations. The charity has produced posters and promotional literature to encourage staff at corporate supporters to participate.
