An energy label describes your home’s energy performance; it is not a price list for its value.
Keep evidence of the work
Keep quotations, invoices and photographs of materials before they are covered. The energy adviser and appraiser need to understand what has changed.
Discuss the report requirement
Tell the appraiser whether the lender needs the current value or also a value after planned renovation. A fixed increase per energy-label step is not a reliable valuation.
Useful tools
Open the calculators or build your document checklist. Request an appraisal when you know the report requirement.
