Advice to help you use this item 

The following advice may help you to use this item, but you do not have to follow it to get paid. It’s not part of this item’s requirements.    

Locating boxes for different species 

Boxes for all species should be kept in their original location if they’re being used. If they are not being used after year 3, ask Natural England for relocation advice.  

Strap boxes to trees with wire and hose or rubber to prevent tree damage.   

Dormice boxes 

Boxes should be: 

  • in ancient woodlands or large hedgerows – avoid isolated trees 
  • in batches of at least 10 (ideally over 50), spaced 10 metres (m) to 20m with around 30 boxes per hectare 
  • 1.5m to 2m above the ground (over 3m if the public have access) 
  • away from footpaths 
  • made of untreated timber 
  • based on the Peoples’ Trust for Endangered Species box construction guidance 

Tree sparrow boxes 

Boxes should be: 

  • in farm buildings or hedgerow trees, ideally near permanent water such as ponds 
  • away from bird feeders or places cats and squirrels can easily access (with a secure lid) 
  • out of the sun for at least part of day 
  • weatherproof with small drainage holes in the floor 
  • made from wood at least 15 millimetres (mm) thick with a 28mm entrance hole – follow the RSPB and British Trust for Ornithology guidance 

Bat boxes 

Boxes should be: 

  • large enough for a maternity colony to cluster to conserve heat 
  • dry, rainproof and draught-free, with no gaps where the sides and top join 
  • entered by a slit at the base (front or back) no more than 15mm to 20mm wide – follow the Bat Conservation Trust guidance 
  • preservative-free if made of wood 
  • out of the midday sun 
  • close to a hedgerow or tree line 
  • placed with other boxes facing in different directions to offer a range of temperature conditions   

Solitary bee boxes 

Boxes should be: 

  • in a dry, sunny and sheltered position on farm buildings, a post or freestanding with a raised base to prevent rising damp 
  • near pollen and nectar forage 
  • 50 centimetres (cm) by 50cm and 20cm deep, open fronted but with a back 
  • made of untreated timber 
  • weatherproof with small drainage holes in the floor 
  • contain at least 4 compartments, packed tightly with drilled hardwood blocks, bamboo stem sections and reed stems or paper drinking straws 

Keep the box in its original location if it’s being used. If it is not being used after year 3, ask Natural England for relocation advice. Strap boxes to trees with wire and hose or rubber to prevent tree damage.   

Protected species 

Bats and their roosts are protected under the Wildlife and Countryside Act 1981. It’s an offence to disturb, handle or kill bats. Anyone who inspects bat boxes that have been or are being used by bats needs a licence from Natural England.
