As per the E and F class, the [[flotilla leader]]s were built to an enlarged design, incorporating a fifth 4.7-inch gun in 'Q' position, between the funnels and were based on the F-class leader, {{HMS|Faulknor|H62|2}}.<ref name=w7>Whitley, p. 107</ref> ''Grenville'' was shorter and heavier than ''Hardy'' as she used compact [[Yarrow boiler|Yarrow-type side fired boilers]] while ''Hardy'' was slightly beamier. They displaced {{convert|1445|-|1465|LT|t}} at standard load and {{convert|1953|-|2033|LT|t}} at deep load.<ref name="l59"/> The ships had an overall length of {{convert|330|-|337|ft|m|1}},<ref name=w7/> a beam of {{convert|33.75|-|34|ft|m|1}}<ref>Friedman, pp. 224, 299</ref> and a draught of {{convert|12|ft|6|in|m|1}}. The ships carried a total of 175 personnel which included the staff of the [[Captain (D)]], commanding officer of the flotilla.<ref>Whitley, pp. 97, 107</ref> Their turbines were {{convert|2000|shp|abbr=on}} more powerful than the [[private ship]]s, which made them {{convert|0.5|kn}} faster; their propulsion machinery was otherwise identical. Both ships were early wartime losses and consequently received no modifications.<ref name=l1/>
