east
Relief rain occurs in the west of Britain because moist air from the Atlantic Ocean is pushed up and over the higher elevation of the western mountains. As the air rises, it cools and condenses, forming rain clouds. This results in more rainfall on the western side of Britain compared to the eastern side.
The windward side.
Well it would be the eastern side.
The prevailing westerly winds carry moist air from the Atlantic Ocean, which results in more rainfall on the western side of Britain. As the air rises over the western hills and mountains, it cools and releases moisture in the form of rain. In contrast, the eastern side of Britain is in a rain shadow effect, so it receives less precipitation due to the mountains blocking the incoming moisture.

Britain's side
More rain generally falls on the windward side of a mountain range. As moist air rises up the mountain slope, it cools and condenses, leading to the formation of clouds and precipitation. The leeward side, or the rain shadow side, tends to be drier as the air descends and warms up, causing it to hold onto moisture less effectively.
The North and West of Britain has more rain than Southern and Eastern regions due to weather systems coming in from the Atlantic.
