The GRID Mora on the Jeppesen charts applies to a square of Lat & Long.
If you look on E(LO)2 just left of Berry Head (N50:23 W003:29) you shall find the numbers 32. This indicates within the block from N50 to N51 and W003 to W004 the Grid Mora is 3200 ft amsl. It includes a safety factor.
In the introduction legend have a look at Page 57 the vast majority of Jeppesen chart questions can be answered from this page.

MORA stands for minimum off route altitude. It extends to ten nautical miles either side of the airways centreline. It takes the highest elevation/structure within the one degree area and adds on a buffer of 1000 feet. Above 5000 feet it adds on a buffer of 2000 feet. If you see a plus and minus sign alongside the grid mora it means that the figure may not be accurate.

Grid Mora
The question was about Grid Mora.
As I understand it and was taught grid mora is a jeppesn derived term and refers to the grids on the charts. There is a full definition (which everybody should read in book 1 of the jep manuals. (Full set not the student handout)
Grasscarp. You seem to be getting confused between en route Mora and grid mora.

On your charts the large numbers - one large and one small in the middle of a Grid Square are your Grid Minimum Off Route Altitude.
This value is the tallest obstruction in the grid square rounded up to the nearest hundred feet. There should be a thorough definition in the front of your Jeppesen and a page at the back of the glossary naming all of the symbols. The Grid MORA should be on that page, too.
