I’ll go first and give Berkhamsted, on the edge of the Chilterns, 5/10. 

I’ve lived in various parts of the UK over the years and think this is a reasonable score. One thing I’ve noticed is that the general picture is that the north is snowier than the south (no surprises there), but there are big differences within the regions themselves. There are parts of the north that are dreadful for snow and parts of the south that are relatively decent.

That they do!

1980s - 10/10 (1987 aced it)

1990s - 8/10 (1991 amongst others was awesome)

2000s - 6/10 (the last true easterly)

2010s - 5/10 (the BftE saved it)

2020s - 1/10 (one snowcover at 9 AM event)

It's why, incidentally, I've never wanted to move from here. In the right conditions - so rare nowadays - it can be one of the snowiest places in the country.

If snow falls we need a frost to keep it which is hard with the sea on three sides. If any Atlantic systems move in whilst cold air is over us any snow will soon turn to rain if it doesn’t start as rain in the first place.

The area I was brought up in which was on the eastern side of the Peak District I would rate as a 10. Any snow from the east would move across Lincolnshire and hit the hills and leave large amounts..sometimes. Depressions from the west could give blizzard like conditions if the cold air was already in place. A NW wind did OK as well. The only truly dry direction was a direct northerly but this was extremely cold. Happy days

He's right - I'd give Chichester a grudging 1/10.

My previous home of Birdlip (just shy of 300m asl in the Cotswolds) was a solid 8 out of ten. I had laying snow of at least 15cm in every year of the 6 that I was there and numerous smaller falls. It also snowed in every November and April that I was there. Absolutely fabulous in winter.

We seem to miss out on snowfalls that many others get (1987, 2018 'bfte', as well as some less notable events), but enjoy falls when other areas miss out (essentially, easterlies are generally dry, but cold NW'lies bring convective snow/graupel showers and the occasional small front)

We've had snow lying (criteria: a min 1cm for at least 6 hours) almost every winter. And some have lasted several days. But I don't think we've had any over 5cm since 2013, most ranging 1-2cm. Indeed, in my lifetime (53) we've never had a real bonanza fall (+30cm) like a lot if areas seem to have done 

Trying to judge against other places in the UK, I'd give:

For regularity:  6/10

For depth/quality:  3/10

1983-2008 I lived just south of Nottingham and again a decent area for snowfalls, especially from the east I'd score it 6/10

Since 2008 I've lived in Edinburgh, 2 miles south of The Castle. Being on the coast and well sheltered by the Highlands the city itself isn't brilliant, I'd say 5/10. However Nov/Dec 2010 was incredible with over 20cm for a month! If I travel a few miles south into The Pentlands & Borders then snow frequency increases rapidly

You're about 35 miles from me. I've just quickly scanned my Google Photos and since 2016 I've recorded these snow events when several cms or more accumulated for a day at least. I've omitted some falls, for example the two recent November ones because the snow didn't hang around for long enough.

Seriously though we tend to do well when the wind is from a northerly quarter but are more sheltered from anything from the west by the mountains. Anything from the east (off the sea) is almost always wet rather than white. Overall I would say 6 out of 10. 

CC could well be right though. Allow first of all for the height difference and heat island effects between High Wycombe (the clue is in the name) and Croydon. 

Then in the 26 years I lived in Kent (1976-2002) I can remember several frustrating instances of snowfalls from the NW fading out before getting to mid-Kent; equally there were a few glorious snowfalls from NE-lies e.g. Thames streamers which smothered Kent but had little or no effect on S London.

Sorry, I wasn't suggesting he was wrong. I drew attention to it because it highlights that differences within regions can be almost as great as the north to south split.

If Croydon is a 1/10, then what is Kingston upon Thames?

Firstly, I’m on the wrong side of the A3. Yes, correct  and also on the wrong side of the M4, hence I call it the snow desert of Surrey.

IMO Croydon is actually a much better place for snow. Many times I call my friend and he sends me pictures of his snow-covered garden, while I get the occasional sleet shower at best. If I’m lucky, I might see a bit more if I go to David Lloyd Raynes Park, which is surprise  on the other side of the A3.

Very similar if not even a bit worse here in Richmond at about 6m asl.  Where I come from in Bromley, Kent and where I lived for many years in Sutton, Surrey the higher ground, distance from the London Heat Island and the slightly further east longitude make them a lot more favourable. On my photo collection of the last 17 years Feb 2009 stands out as the best as in Richmond we got about 15cm from a Thames Estuary streamer and then Dec 2010 (10cm) from a small perturbation in the easterly flow. Feb/Mar 2018 gave about 6cm then Jan 2013 and Jan 2010 4cm and Jan 2021 1-2cm

That's everything apart from some dustings in the last 17 years so about 2/10 for me

I think Putney Heath where I used to live gets more and its closer to London but also to the Thames!
