I have an ASCII grid with a cell size of 1km2, I was wondering if there was a way to aggregate these cells into 5km2 grid squares. I initially thought of using RasterResampler, but there is no option to sum the attributes.
For those familiar with ArcGIS i esentially want the equivilent of the tool 'Aggregate'

I'm sure that solves my problem however, as the interpolation type i require is a sum of the atributes, whereas the rastermosaicker and rasterresampler only have averaging, nearest neighbor etc.

Then i assume u have overlapping gridcells.
you can use rasterexpressionevaluator for such.
There are good examples in the knowledge base here. Just search on the topic of rasters in there.

Typical case for some math on the cell values, I would think.
Essentially calculating the desired value and applaying the difference to each cell can preserve the raster properties and change the cell values to the desired value.
