The TomTom came up with the best route home. M25 clockwise as far as the problem area then across to the M40 and up the A43 to join the M1 higher up. Then M18 and A1 as usual.
The problem was half way up the M40 we stopped at a services for a toilet break and it started snowing heavy. By the time we got back to the Jeep the car park was jam packed with people struggling to get out. It took us an hour to get back onto the Motorway.

Then after that the M40 and A43 were really bad with snow. It was lying right across all the lanes. They must not have gritted it enough.
Once onto the M1 though it was no problem. Just heavy traffic as usual.
