These units were formed in 1915 and are sometimes known as 148, 149, 150 and 151 Brigades RFA.
By February 1915 Lord Derby Derby had obtained from the War Office permission to raise the four artillery units required as part of a complete division. They would soon enough be granted the formal titles of the 148th to 151st Brigades of the Royal Field Artillery and were all sub-titled “County Palatine”. The brigades were established at Lytham St. Annes where they began training largely without proper uniform, equipment, transport or accommodation. It took several weeks for the full complement of men to be attracted to them. Each of the four brigades was essentially made up of men from a particular area but it is clear from the surviving service records that there was a certain amount of blurring.
CXLVIII (County Palatine)
This brigade joined 30th Division at Grantham by 13 August 1915. It comprised A, B, C and D Batteries, each of four 18-pounder field guns. You can see details of its battles and movements on the page describing the division
https://www.longlongtrail.co.uk/army/order-of-battle-of-divisions/30th-division/On 16 May 1916 the Brigade’s Ammunition Column left to be merged into 30th Divisional Ammunition Column.
On 21 May 1916 D Battery left and joined 151 Brigade as its A Battery. It was replaced by the arrival of A (Howitzer) Battery from 151 Brigade, which was then renamed as D (Howitzer) Battery.
On 25-26 August 1916 C Battery was broken up, and its two-gun sections joined A and B Batteries to bring them up to six guns each. A Battery joined from 151 Brigade and became 148 Brigade’s C Battery.
On 2 January 1917 a two-howitzer section joined from D (Howitzer) Battery of 150 Brigade and was added to D (Howitzer) Battery.
If he went to Egypt and not France then he must have transferred after Lythan St Annes because 148 went to France.
