VATS – Ventilation and Air Tightness Strategy
As well as retrofit designs, ECO4 Gurus also provide ventilation and air tightness strategies with ventilation upgrade requirements.
With our VATS, air permeability tests (pulse tests or fan blower tests) are almost never required.

How much does a retrofit design cost?
Our retrofit design costs vary between £70 and £285.
The cost of a retrofit design depends on the measures being installed, how the measures interact with each other, as well as the buildings features, defects and limitations. A factor in costings also depends on the requirements of the Installer and any additional requirements from the funding scheme, client or the Retrofit Coordinator.
Additional costs may be incurred were the designer will be producing heat demand calculations for gas boiler installs, condensation risk analysis, surveyors reports, u-value calculations, etc.
