Most likely cause & what to check
A gurgling or rushing sound is usually trapped air. Bleed all radiators and check the boiler pressure is between 1 and 1.5 bar — this often resolves it.
Look at the pump (a silver or white cylindrical unit, usually near the boiler). If it has a dial showing speeds 1, 2, 3, try turning it to a lower setting.
If the pump is making a grinding or high-pitched squealing sound, it is failing and needs replacing. Call a heating engineer. Tell them: "My central heating pump is making a [describe] noise."
