The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗

Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI 99 m away: Sherrardspark Wood SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Also on the record
Radon affected area, class 2; Inside the Welwyn Garden City built-up area; Green belt 99 m away: London.
Not affected
Outside flood zones 2 and 3 · No listed building at the site · No scheduled monument at the site
