Loft Insulation Upgrades for Better EPC Scores

Heat rises, and an uninsulated or under-insulated loft is one of the biggest causes of poor EPC ratings in UK homes. Current building standards recommend loft insulation of around 270mm depth, but many older rental properties — particularly Victorian terraces common in Leyton and East London — have far less. Topping up or replacing loft insulation is often the single most impactful upgrade.

Loft insulation is relatively affordable, typically costing between £300 and £500 for a standard terrace, and can be installed in a day. It improves the EPC rating, reduces tenant energy bills, and helps prevent condensation and mould issues. Keep your insulation certificate as evidence for your next EPC assessment.

After upgrading loft insulation, book a new EPC with Leyton Landlord Certificates to capture the improvement on your certificate. Call 0800 654 6211 to schedule your assessment across Leyton and surrounding London areas.
