Take everything out of the cupboard below the boiler and take a pic of what is in side the cut out , you dont have to remove the shelf

Nothing stands out to me here:

If I bought an appropriate filling pipe could I attach it to just underneath the boiler?:

Clutching at straws here ,but do you have a hot water cylinder connected to your combi boiler by any chance ?

I did look for one in the airing cupboard by the shower, but that is empty save for a switch for an immersion heater which doesn't work :/ Can't see any piping leading out from the bathroom, either.

Show us a picture ,pointing upwards to show where the pipes enter the boiler
Sorry ,forget that ,you already showed one !!

has the boiler always been in the same position in the house ? did you have a previous boiler installed somewhere else ?

I only moved in a year ago, but I will speak with a neighbour who said her boiler was installed around the same time as mine by the same people.

Ask her where her filling loop is

@AmirMoosavi - yes, there’s nothing behind washing machine

This photo looks promising, try looking again here.

Ask her where her filling loop is

Popped over to hers, it's a Vaillant boiler as well... but she has the filling loop right underneath

Would I be able to borrow her filling loop and valves and use them on my boiler if all else fails?

I had a rummage around with my hand as I couldn't see that well; just felt three pipes, no valves or loop.

Also called the plumbers who installed it. They said the filling loop must be somewhere, but that they wouldn't be able to visit until next year.

No, as hers is built in, Yours isn’t.

It’s got to be somewhere, as your plumbers have suggested. Keep looking in cupboard’s, also near the worktop height, I’ve missed a couple at that level before now. Double check that airing/cylinder cupboard. Is there any ducting/boxing in in the kitchen that has pipes in?

 

[AmirMoosavi]

Double check that airing/cylinder cupboard

That was the trick, thanks Found this hidden behind some loo roll

Should I turn both taps?
