The earliest timeline I've seen possible for Celts in Britain was 800 BC, with 500 BC being the first solid written & archeaological evidence of entrenched occupation.
The Celts are believed to be Indo-European and possibly have migrated from the Russian Steppes, not Egypt. You can see this in their migration across Europe.
Here is a timeline for Brittain.

Your timeline indicates the stone circle time is 2300-1500BC
and the Celtic (Druid) time is 500BC-500AD
I have always had a hard time remembering things like this so I am very glad you put the link to the the timeline.
----bits from Evo's timeline---
c.2300 - Construction begun on Britain's largest stone circle at Avebury.
c.2000 - Metal objects are widely manufactured in England about this time, first from copper, then with arsenic and tin added; woven cloth appears in Britain, evidenced by findings of pins and cloth fasteners in graves;
construction begun on Stonehenge's inner ring of bluestones.
c.1800-1200 -
Control of society passes from priests to those who control the manufacture of metal objects.
c.1500 - ...
stone circles seem to fall into disuse and decay around this time, ...
c.1200-1000 - Emergence of a warrior class who now begins to take a central role in society.
c.600 - Iron replaces bronze, Iron Age begins; construction of Old Sarum begun.
c.500 - Evidence of the spread of
Celtic customs and artefacts across Britain; more and varied types of pottery in use, more characteristic decoration of jewelry. There was no known invasion of Britain by the Celts; they probably gradually infiltrated into British society through trade and other contact over a period of several hundred years; Druids, the intellectual class of the Celts (their own word for themselves, meaning "the hidden people"), begin a thousand year floruit.
