Community Infrastructure Levy

Developments liable for CIL

We have adopted 2 different community infrastructure levy (CIL) charging schedules:

  • 1 in the former Wycombe district area
  • 1 in the former Chiltern and South Bucks district areas

Former Chiltern and South Bucks district area

Developments that are liable for CIL in the former Chiltern and South Bucks district areas include:

  • any new dwellings, regardless of their gross internal floor area
  • new buildings (all use classes) where the gross new build floor area comes to more than 100 square metres
  • a change of use from non-residential to residential use, when the building in question has not been occupied in its lawful use for a continuous period of 6 months in the previous 3 years
  • new agricultural and commercial premises

Former Wycombe district area

Developments that are liable for CIL in former Wycombe district area include:

  • any new dwellings, regardless of their gross internal floor area

  • new retail developments and sui generis akin to retail such as petrol filling stations, shops selling and/or displaying motor vehicles, and retail warehouse clubs

Development carried out under permitted development ('general consent') may still be liable for CIL if it meets any of the above criteria.

Developments not liable for CIL

Developments that may not be liable for CIL in both areas include:

  • a change of use from non-residential to residential use, where the building to be changed has been occupied in its lawful use for at least 6 continuous months of the previous 3 years
