Hello Claire,
No, I don't think there are any Lavender species or cultivars that will tolerate heavy, wet soil.
However if you particularly like Lavender I would not let that put you off. Lavandula are not particularly deep rooted. Depending on how many plants you want in the garden, it would not be a massive project to dig out the planting hole(s), remove the soil and replace it with a 50/50 mix of decent top soil and sharp grit.
Obvoiusly the deeper you dig the holes the more likely the Lavandula plants are too thrive. I would also only plant Lavandula in full sun or very light shade.
Hope I have helped.
