Top tips
Hiring a epc assessor, without the regret.
Four moves that separate a smooth job from a nightmare.
Inaccessible Lofts
If the assessor cannot see the insulation because the hatch is painted shut or blocked, they must assume "unknown" or "none," which significantly lowers your score.
Missing Paperwork
If you have internal wall insulation or floor insulation, the assessor needs documentary evidence (invoices or certificates) to include it in the report.
Old Lighting
Having old-fashioned halogen bulbs instead of LEDs is one of the easiest ways to lose points on an EPC.
Boiler Data
If the boiler's data plate is missing or unreadable, the assessor may have to use a "default" efficiency rating which is usually lower than the actual performance.
Costs & timeline
