Heritage energy-efficiency retrofits

If you have a project in mind, or want to speak with a member of our team - please get in touch.

Improving the energy performance of a historic building doesn't have to come at the expense of its character. At Maydencroft, we offer tailored retrofit solutions that reduce heat loss and energy bills while respecting the building’s fabric, appearance, and ventilation needs.

Many traditional buildings are cold and draughty, but modern materials and methods often risk trapping moisture and causing long-term damage. We take a conservation-first approach — enhancing comfort and efficiency without sealing a building up in ways it wasn’t designed to handle.

Working closely with conservation officers and planning authorities, we help clients navigate what is and isn’t permitted in listed and sensitive buildings. We design and deliver upgrades that are practical, sustainable and compliant.

Our retrofit services include:

• Secondary glazing for historic windows
• Internal wall insulation using breathable systems
• Roof, loft and floor insulation
• Air source & ground source heat pumps and mechanical ventilation
• Improved draught-proofing
• Low-energy lighting and heating controls

We also support clients looking to improve their building’s EPC rating or meet sustainability targets. Whether part of a wider restoration or a standalone energy project, our retrofits help bring historic properties up to modern standards — without losing their soul.
