Your starting point

Think beyond completion day. Build a routine for maintenance, shared-building matters, insurance and the obligations that apply to your property.

An energy certificate is one source of information about a building's performance, not a guarantee of your future bills. Use the steps below to organise a decision, not to infer an official approval, a guaranteed price or a universal deadline.

Work through the decision

Energy Certificates and Home Comfort — a diagram of the key planning steps
Planning diagram. The same steps are described in the text below.
01

Read the property details

Check that the certificate relates to the actual home and understand its stated scope.

02

Review recommendations

Ask a qualified professional which improvements are suitable and what they would cost.

03

Combine evidence

Consider ventilation, equipment, orientation and intended use alongside the certificate rating.

Adapt this to your circumstances

Keep citizenship, current residence, household needs and the location of the home separate in your notes. Ask the responsible authority, institution or qualified professional to confirm any requirement that affects your situation. A checklist used by another household may not apply to yours.
