I have finally found it.
The best antiques market near London is at Kempton Park.
For those of you without a car, don't fret- there is a train station in the parking lot and plenty of vans ready to deliver your goods straight to your door.
Word of warning? Arrive early. We arrived at 6.30am and 4 hours later, I still felt like I wasn't finished. Upon opening, many dealers will only have a small selection of their items out. An hour later, every stand will be unrecognisable and new goods will appear with every pass.
I brought the above home with me and if the sideboard wasn't so large, you can bet I would have bought more! Many people bought the large baskets on wheels (laundry baskets?) and then used them to hold everything they bought which was genius.

Station: Kempton Park
Trains depart from London Waterloo and take 45 minutes direct.
The market takes place the second and last Tuesday of each month.
Don't worry about bringing food, the food truck makes surprisingly yummy toasted breakfast sandwiches.
