Energy Efficiency in Listed Homes: What’s Possible (and What’s Not)

Introduction

If you own a listed home, chances are you’ve wondered: how do I make it warmer, greener, or more comfortable without breaking the rules? The good news is, while not every modern upgrade is possible, there are plenty of sensitive improvements that can make a real difference.

What’s Possible

• Secondary glazing: slim-profile systems can be fitted discreetly, keeping heat in without replacing original windows.

• Breathable insulation: natural fibre insulations (like wood fibre or sheep’s wool) allow old walls to “breathe” and avoid trapped moisture.

• Draught-proofing: small interventions around doors, windows, and floors can transform comfort levels.

• Efficient heating systems: modern boilers, zoned controls, and underfloor heating (where appropriate) can reduce energy use.

What’s Not (or Needs Care)

• External insulation: often not permitted, as it changes the character of façades.

• uPVC windows: usually rejected in listed buildings, as they alter appearance and fabric.

• Sealing everything airtight: historic buildings need ventilation to stay healthy.

Closing Thoughts

Improving energy efficiency in a listed home is about balance. You won’t tick every box on a modern sustainability checklist, but you can create a more comfortable, resilient, and efficient home without losing the soul of the building.
