Derbyshire divides along a line most people can see on a map. The north is the Peak District — tourism, hospitality, holiday lets and rural service businesses covering wide areas. The south, around Derby, Chesterfield and the Erewash valley, is industrial, with an engineering and rail base and a quite different commercial rhythm.
The Peak District is a visitor economy
Bakewell, Matlock, Buxton, Castleton and the surrounding villages run on visitors, and the seasonal swing is severe. Accommodation, hospitality and attractions feel it directly; trades, cleaning and property services feel it through their customers.
Holiday-let services in particular are a real and lightly contested category here — changeover cleaning, key holding, property management for absent owners. These are searched by owners who frequently live elsewhere, which means the ranking needs to happen where the owner is, not where the property is.
National park constraints are content
Building, extending or altering property inside the national park carries planning constraints most owners do not understand. For builders, architects and surveyors, a clear page explaining what is and is not permitted in the Peak District is genuinely useful, almost entirely unwritten, and attracts exactly the clients who need professional help.
The south is engineering
The Derby area carries a concentrated rail, aerospace and engineering base with a substantial supply chain. As with other industrial clusters, that work is business-to-business, won on capability and accreditation, and largely untouched by local search.
Chesterfield and the former coalfield
Chesterfield and the north-east of the county have their own economy and identity, oriented as much toward Sheffield as toward Derby. Businesses there should be clear about which way they face, because the two catchments barely overlap.
