Air conditioning for listed buildings

Climate comfort for Grade I, Grade II, and conservation-area homes — engineered without external condensers, without altering protected fabric, and without compromise on comfort.

The challenge

Why standard AC won't work in heritage homes

Listed properties impose strict limits on what can be installed, where, and how. A conventional split system is almost always the wrong answer.

Planning & consent constraints

Listed building consent and conservation area rules typically prohibit external condensers, visible pipework, or any alteration to protected façades — ruling out standard split systems.

Protecting period fabric

Original plasterwork, panelling, cornicing, and sash windows must be preserved. Installations demand careful routing, reversible fixings, and finishes that respect the building's character.

Limited service voids

Heritage properties rarely offer ceiling voids or riser space. Systems must be engineered around solid walls, thick timber floors, and existing structural constraints.

Our approach

Solutions engineered for heritage properties

We specialise in systems that satisfy conservation requirements while delivering modern, whole-home climate comfort.

Water-cooled systems

Chilled-water or hydronic systems remove the need for an external condenser entirely. A single, discreet plant location serves the whole property through slim, low-impact pipework.

  • No external units required
  • Ideal for façade-protected properties
  • Whisper-quiet operation
  • Compatible with fan-coil or chilled-beam terminals

Internal-only VRF with disguised termination

Where a suitable internal plant space exists, VRF technology can be engineered with condensers concealed in cellars, courtyards, or roof voids — invisible from every protected elevation.

  • Zoned climate control per room
  • Grilles finished to match period joinery
  • Concealed pipework in reversible chases
  • Full recovery of heat between zones

Underfloor cooling & chilled ceilings

For the highest-specification restorations, radiant cooling delivers imperceptible comfort with no visible terminals at all — perfect for state rooms and formal reception spaces.

  • Zero visible equipment
  • Silent operation
  • Even, draught-free temperature
  • Integrates with underfloor heating
Our process

From listed building consent to lifetime care

01

Heritage-aware survey

We assess the property alongside your architect or conservation officer, documenting listed features, planning constraints, and viable service routes.

02

Consent-ready design

We produce a design pack — including a heritage impact statement where required — to support your listed building consent application.

03

Sympathetic installation

Our in-house engineers install with dust protection, reversible fixings, and bespoke joinery details that leave the fabric untouched.

04

Ongoing stewardship

Discreet, scheduled maintenance keeps the system silent and efficient — with the same team who installed it, for the lifetime of the property.
