Hello, what boiler is it? (I’m thinking Vaillant with the spanner sign). Your looking for an internal loop, an external loop, or if you’ve one installed a Jepp valve/similar. A Photo (under the boiler) may help.

Ok, firstly have a look under the boiler, behind that boxing in (looks like it’ll just pull out). Post another photo if you’re unsure of what to look for.

Now you have found the filling loop - it’s an internal one with 2 blue handles. One going across the pipe and one pointing down, on the right hand side. Open one up, then slowly open the other one and raise the pressure to just over 1 bar.
