The English Channel is rather shallow, so it wouldn't be completely inconceivable to imagine it as a lowland similar to the Netherlands. If this was a flatland linking France to England, how do you think this would affect the climates of the surrounding areas? Looking at how the Channel affects climates like Boulogne-sur-Mer, Calais and Dover, I guess this could actually make a fair bit of a difference even though it'd only be something like 15,000 extra square km of land.
I think this would render London to have Paris-like summers and winters similar to Scotland, with vaster cold snaps, since a lot of winter southerlies would travel over more land and not be as mild. with the reverse effect in summer. The net warming of Paris would probably be lower. Southerlies already travel over land, but winter cold snaps would be stronger instead. Brussels being farther inland on the other hand, could probably reach 26°C summer average highs from the current 23°C without the direct inflow from the English Channel and the cold waters. Where Belgium meets Germany and the Netherlands the impact would probably be lower since the North Sea would still be there.
Scotland could possibly get slightly warmer summers since high-pressure air could be warmer with a direct land link, but I feel winters wouldn't change much since low-pressure systems dominate by then anyway.
So, my guess would be:
London: 25/15 & 6/1 Birmingham: 23/13 & 5/0 Portsmouth: 23/16 & 7/3
Paris: 27/15 & 6/1 Brussels: 26/13 & 3/-3 Cologne: 25/14 & 3/-2 Amsterdam: 24/14 & 4/-1
What about you?

London would yield a climate similar to that of Berlin's, albeit damper and cloudier. Similar latitudinal parallel between the both of them.
Settlements such as Derby or Leicester (Central England) would see rather cold, snowy winters. Farther to the North-East, such as Berwick-upon-Tweed, would see much snowier, damper winters (albeit milder), and of course squallier conditions annually than the likes of Derby.
Higher up, such as Alston (~300 m AMSL) or Nenthead (~450 m AMSL), winters would be very cold and tremendously snowy, alongside the Helm Wind which blows off from Cross Fell. Winters down in Alston should average even colder than what Great Dun Fell does currently: –5° / –0° C, instead of –1° / 4° C (Alston's current midwinter averages).
It would be a much better climate, to put it as simply as I can.

Warmer summers no doubt since the sea wouldn't cockblock so many warm systems from the south, although the freezing winter predictions seem fanciful. The mild air from the Atlantic in the west would still be dominant, and the colder systems tend to travel in from the cold seas of the north and Siberia out east. Aside from that, most of Europe would now be speaking French or German  |

London would have a climate like Paris, with warmer summers and colder winters than it currently has.
26/15 and 6/1

Paris averages 16° / 25° C; there is absolutely no way that London can be warmer than Paris (unless of course you count the extra UHI codsawallop, which let's face it—must not be counted). NOTE: Mistake! I didn't think that Paris would also be affected by this extra landmass straddling the English Channel, so pardon my misunderstanding(s). |

Paris averages 26c in July. |

The mild air from the Atlantic in the west would still be dominant, and the colder systems tend to travel in from the cold seas of the north and Siberia out east. Up on your latitudes, winter differences would be quite minimal since westerlies have a natural path. Hawarden would be a touch more seasonal in this scenario mainly because of summers. Say 22/12 and 6/0, since there would be more continental air present in the south and your area being inland after all. Manchester would also be a bit more seasonal (21/13 and 6/0). Liverpool, Dublin and Blackpool would be quite unchanged though. Considering southerly inland areas, I know that the English Channel plays quite a key role in the really mild winter spells here, when the wind takes that path and then crosses over the North Sea on the way here. If that was tempered, the latitude would still be high enough to cool London down almost 2°C during winters, but nothing like in Whaler's Berlin scenario...
Even up here there would be some differences. Winter rain would be less common and winter record highs would lower. Summer heat waves would also be a bit stronger than today, since the dominant south-westerly pattern would be carrying more inland momentum and raise North Sea SST's a bit in summer, while lowering those in winter. Probably a 0.5-0.7°C avg high difference up to Stockholm, which is a key peninsular dividing line. In winter it'd be perhaps 0.3°C colder due to the absence of the very warmest spells. So it'd even affect Northern Europe some to lock the Channel, but our days of being warmer than Amsterdam in summer would most likely be over, since it'd be rather equal.

No wait, now the English Channel is sea again, but the Dogger Bank is filled. No wait, one more change: the whole of the North Sea is now land.

These scenarios of been done to death.
It would make winters in Southern England slightly cooler nothing spectacular... And summers slightly warmer.

london would be like brussels, but slighly colder in summer. How would that work? London would get warmer summers than it has now. |

that's due to uhi.

London would get warmer summers than it currently has, without the English Channel to slow down any southerly heat. It would be like the current Paris climate. London summers are already warmer than Brussels, even without the UHI. |

London would get warmer summers than it currently has, without the English Channel to slow down any southerly heat. But there's nothing stopping Brussels from yielding even warmer summers than London has with that new landmass, thereby making London cooler than Brussels either way (in Summer, that is). |

London summers are already warmer than Brussels, even without the UHI. true. but the "colder" winters would more than offset the slightly warmer summers. look at the geography. only reason brussel is colder in summer is due to london's uhi. or give me another explanation. |

London summers are already warmer than Brussels, even without the UHI. true. but the "colder" winters would more than offset the slightly warmer summers. look at the geography. Which is exactly what I said. It would be like the current Paris climate, about 2c warmer in summer and 2c colder in winter. Well for one, UHI doesn't effect the daytime highs. Two, neither Heathrow nor Kew (which is in a frost hollow) are in the UHI, and both are warmer than Brussels. As I've said millions of time before, it's due to the hills that shelter London to the north and south, as well as London sitting in a depression. |

so the avg annual temperature in london would be colder. that's what i meant.

The current south coast would have much warmer summers, much colder winters and probably quite a lot cloudier.
