Hi Yummymummy
Our local hospital has just started doing BFing classes for first time Mums and Mums who wanted to or have bf before but had problems. Having said that I found out about them on the hospital's website and not through my MW.
Some NCT Antenatal Courses offer breastfeeding information from a trained Bfing Counsellor. Have a word with your local NCT booking clerk, you can find them through \link{http://www.nct.org.uk/this}
You may not have to go to weeks of classes as many NCT branches now offer courses such as a single day.
I didn't have any classes but did go to a group where many mums were bfing and found it to be good support. A good group where you can go when you are pregnant or bfing are the baby cafe's

All the mums will be bfing and there will be support of trained staff available and in private if you prefer.
La Leche League also run groups where you can meet up. You can also get support and information over the phone or online with trained bfing counsellors:

and the NCT welcome everyone, no matter how they feed their baby but some branches do run bfing groups, most will run a group like Bumps & Babes where you can go and meet other mums and there is usually a mix of bfeeders & bottle feeders there.
Oh, and I would just like to reiterate, have the numbers of the breastfeeding support lines handy and don't be afraid to use them. My HV was hopeless, hadn't even had kids let alone bf and my MW wasn't much better. Without the support of people who had bf and then done the training, and the support of my lovely DH I would have never managed!
Hope some of this helps.
