Beachy Head Suicide Spot, Chaplaincy Donation?

I will be guiding several visitors to Beachy Head to see the dramatic views and to stand on the clifftop and experience the North Sea wind. Unfortunately, the best viewing spot is also a renowned suicide venue. The cliffs are not set off by fences or walls and it's a 530 straight drop to the rocks below.

While there I want to make a small donation to the chaplaincy team that patrols the area looking for despondent/missing/suicidal people. Is there a donation box? Or some other receptacle where one can leave a cash donation? I'm sure there's a way to do this somewhere on the net by using a credit card or PayPal, but the experience would be more enriching if one can leave a modest anonymous donation in person, 'in situ' 'ex tempore', right then and there; say GBP 20 as an indicative amount.

I also know there's a duty chaplain I could ask, but they may be on patrol or otherwise engaged. I have also telephoned them but the admin lines were not attended to.

Question: is there a box, or bucket, or bin where one can make a donation to the chaplaincy team? I am sure there's a way via the net but that's not what this is about.

Secondarily: is there any way to get to the lighthouse by foot? A place where there are stairs or it's otherwise safe to climb down and walk along the sea?
