It's going to be tough this time of year on just about every water in the country, even for experianced anglers.
As for waters near Bedfordshire you could always try Pixies Mere which is just outside Berkhamsted, so not too far from scum town.
Sorry as a Watford fan i can't bring myself to type that town!

It is a great looking lake of about 4 acres which is stuffed full of features and it does produce fish during the winter months.
Stock wise it has a very large head of 10+ mirror, commons and ghosties with a good head of 20's to back them up.
Last year it had another 5 fish between 25lb and 30lb stocked.
If you look at the map on the web site then the swims that always seem to produce fish are pegs 14-17 down near the cottage, 35-37 the point swims and my personal favorites specially this time of the year, pegs 25- 27 the deep hole swims.
All in all a very nice lake with some great fish in thats not to hard to winkle the odd fish or two out of at this time of year, providing you put the effort in.
Hope it helps
