Noisy water pipes

You don't have to keep calling  it a stop male chicken, just type stopcock without the space, which is the correct way!

But stop male chicken is very funny!

I solved my wayer hammer by changing the ball valve to the loft cold water tank, that was the problem. I spent a while scratcing my head but the cause was obvious once I realised the sound continued after the tap was shut off - as the tank re-filled. Adjusting the flow rate of the male chicken tap made no difference.

Whoa, JuzaMum!
Before you spend money, or install stuff, let's try and figure out what the cause is.
First, what is the actual noise? A harsh roar? A deep hiss? A 'bang' when taps are opened and closed?
And, what is your mains supply like? When you run your kitchen cold, or garden tap, how would you describe the result? Gushin'? Splashing? A jet from your house that reaches the bottom of your garden? An impossible-to-stop flow using yer thumb?
And, could you place a container under either of these taps, and turn it on full for 6 seconds. Measure the litres, and times it by ten to get 'litres per minute', please?
This pipe - is it bare copper?

Quick answer without testing the flow (I've just got up), it's more a harsh roar, my youngest child said 'it's like the sound of a tap but louder'. I believe the pipes are bare copper behind the plaster board

Update 7 litres per minute from the kitchen tap

Thanks.

Ok, so it's the usual noise of water flowing through a pipe, probably exacerbated by the turbulence from it passing through a tap or valve. Usually, when it's this noticeable, it's down to excessive water pressure, and a PRV - Pressure Reducing Valve - can help this a lot. 

However, your kitchen water flow is pitiful! Ok, 'flow' and 'pressure' are different things - you can have one high and the other low, but they are connected. 

It's possible that your kitchen tap is an 'eco' type with reduced flow, so doesn't represent what your incoming mains is like. Do you have a garden tap? Could you carry out the measuring test there too, please?

And, when the kitchen tap is on, does it appear 'forceful'? Any chance of stopping the flow with your thumb or palm?

Finally, does the sound vary depending on what tap is being used? Toilet being flushed? Shower being taken? 

Do you have a combi boiler?

How about stop d..ck😊

We get a grating noise when water fills after loo flush.  Any ideas?

More info.

What type of inlet valve does the cistern have? And describe fully the noise, from flush to silence. Ideally a wee clip on YouTube?

Not at home at moment.  Its a bit like car starting motor when engine doesnt start.

It's not easy to cover the kitchen tap due to the design, it's certainly not forceful. 
I will test the garden tap later.
Running the shower or bath seems to be the noisiest, toilet flushing doesn't seem to be noisy.
Yes, we have a combi boiler (new this year, but problem existed prior)

Let's see what the garden tap says.
What about shower flow and pressure - gushing?

A pic of the inlet valve when you can would be good.
