DH works for a rail company so we both get free train travel and free parking at stations run by his company. I don't commute by train any more but DH does. His season ticket would be about £1300 a year and parking about £600.
We also get 75% off on trains not run by his company which can come in handy for weekends away to places we don't need a car for.
I get a free health plan with work (well, it costs me about £5 per month in tax) and I can claim back a few hundred pounds for different things (dental, optical, different therapies). I usually make sure I claim what I can.
Friend works for Virgin Media so we get friends and family package which is slightly cheaper than we would pay.
My brother's a builder so we have never had to buy wood for our logburner he'll drop a load of scrap wood off periodically, though we need to saw it to size. Not as pretty as logs but saves us about £200 a year.
I'm partially sighted so can't legally drive. I get a free bus pass, though it's off peak so can only use after 9.30am. It still saves me about £40 per month compared to paying full price for a standard pass (I pay to get to work but not to get home, iyswim)
Quite a few bits and bobs now I think about it
