Buying with a PEB: questions to ask

Start with the evidence

Ask for the complete PEB certificate and the documents available for the property. Keep what a document says separate from what a seller tells you and what still needs checking.

• Does the certificate refer to the property and unit you are considering?
• What evidence supports the stated insulation, heating and renovation work?

A certificate does not answer every buying question

A PEB is one source of energy information. It does not by itself establish the current physical condition, the full scope or cost of future work, or whether an alteration was authorised.

• Which statements are documented, and which remain assumptions?
• What needs a further document, clarification or professional examination?

Before making an offer

Write down the decisions you are trying to make and the information that could change them. A deadline makes prioritisation useful; it does not establish expert availability.

• Which questions should go to the seller or agent before your decision?
• What is still unknown about the roof, envelope, heating and planned work?

When a technical visit may help

A professional visit may help with questions about accessible building elements that documents cannot resolve. The professional, agreed scope, price and timing must be confirmed before you proceed. A written report is not included by default.

• Which specific uncertainties would you like the professional to examine?
• Would a document-focused review be a useful first step?

Apartments and common parts

Separate information about your unit from information about the shared building. Ask the seller or syndic for available decisions and supporting documents; do not assume private and common responsibilities are settled.

• What is known about the roof, common heating and planned shared work?
• Which co-ownership decisions, documents and responsibilities still need clarification?
