We have strong biodiversity values towards the installations of energy efficiency measures that we fund and we have regard for conserving biodiversity in all our actions within our network.

Installer Requirements

PAS30302014The PAS 2030:2014 provides a specification for the installation of such measures in existing buildings within the remit of the Green Deal and Energy Companies Obligation (ECO) Financing Mechanisms.

Section 5.2.4 of the PAS 2030:14 relates to duties around the presence of protected species, stating that:

“In the event that species (e.g. bats, birds, butterflies, dormice) or plants that could be subject to special protection are found to be present at the designated location, the surveyor shall include report of that presence in the survey record and make the presence known to the GDP and installer”.


Law protects many species of plant and animal in England, and their habitats.

Protected animal species Protected plant species
• all species of bats • creeping marshwort
• great crested newts • early gentian
• hazel dormice • fen orchid
• otters • floating water-plantain
• badgers • Killarney fern
• water voles • lady’s slipper
• wild birds • marsh saxifrage
• reptiles • shore dock
• invertebrates • slender naiad
• protected plants
• ancient woodland and veteran trees
• freshwater fish
• natterjack toads
• white-clawed crayfish

Many other plants are also protected. Click here for a full list (opens new window).

Supporting Biodiversitybee

The law, together with the PAS 203:2014 clause, places a duty on all certified and accredited Green Deal and ECO installers. We reinforce this by requiring our installer network to consider how wildlife or land may be affected in their work, in particular when deciding how to deal with waste and pollution; making decisions about energy and water use; and sourcing wood or plant products.

We do this because their installation activities can harm wild birds particularly during breeding season because of:

  • creating noise, lighting and vibration
  • renovating, converting or demolishing a building
  • cutting down or removing branches from an old tree
  • managing or cutting down woods and hedgerows

Construction work can kill or damage plants directly due to:

  • changes made to the soil, such as adding rubble or nutrients, also affects plants.
  • groundwater changes can make the soil too wet or dry.

All these activities can also affect habitats nearby.

The scope of regard for biodiversity is for existing buildings, extending to gardens, roads and verges, housing and waste ground.

Our approved contractors are expected, when working on sites and buildings, to:

  • preserve and improve habitats for wildlife, including roosting and nesting sites in buildings
  • consider the impact caused by use of energy, water, and chemicals, or by air, noise and light pollution

We aim to measure commitment to our biodiversity values during our pre-qualification process for the approved contractor list and during annual audits.
