- Analysis has taken the variants of size and location and applied these to service charge cost expenditure within the different classifications of parks to provide a simple benchmark. The usefulness of these results is very dependent upon the size of the individual database in each classification and the number of parks included is shown in the table in brackets alongside the appropriate rate 
 
 - The highest rate was £2.28 per sq ft for Shopping Parks in the South, over 200,000 sq ft, while the lowest was £0.44 per sq ft in Bulky Goods Parks in the South under 100,000 sq ft

 - Earlier analysis of size and location shows that the rate per sq foot will decrease with size, and be lower in the North. A qualitative effect can be anticipated and for Shopping Parks to be the most expensive and Bulky Goods the lowest 

 - With Bulky Goods Parks, the medium and large size parks in the North increase with size, but this analysis uses data from a small database and is considered to be the reason for this apparent anomaly 

 - Results for Retail Parks follow the expected influences of size, location and classification 

 - The small database of Shopping Parks included in some of the groups produces limited data to analyse, but the medium and larger Shopping Parks are showing increasing costs and as last year it is considered this will be a qualitative effect running counter to the economies of scale
