They don't.
Neptune is −218°C (55.1K / -360.4°F).
Uranus is -224 °C (49K / -371.2°F ).
Neptune, the 8th planet, is the furthest planet from the sun, however it has an exposed core composed of extremely hot molten ammonia. Which provides a little heat to the planet, but still not enough to prevent it being freezing.
Because of Neptune's very hot core, Uranus, the 7th planet, is the coldest.
Their cold temperatures are because they are too far from the sun for its heat to warm them.

Uranus
How are Jupiter and Saturn different from Uranus and Neptune?
One the main differences is that Neptune has a source of heat deep inside the planet. So, even though it's much further from the Sun, Neptune's surface temperature is about the same as the temperature on Uranus. Also, the heat source is probably the cause of the more active weather systems seem in Neptune's atmosphere. Also, Neptune is denser than Uranus. So, even though Uranus has a slightly larger volume, Neptune has more mass. Uranus has a "weird " tilt. Its axis of rotation is tilted by about 90 degrees. Neptune has a more normal tilt, roughly similar to Earth's.
