We selectively work with clients who share our environmental ethos — delivering ecological awareness from design through to completion, with energy efficiency that pays for itself.
Members of the Passivhaus Trust, building to the world's most rigorous low-energy standard — both new builds and EnerPHit retrofits.
The only Green Building Store-approved MVHR installer in Bristol & the South West — and one of just six nationwide.
Founded by Ben East, an eco-builder with nearly two decades of green building experience and a values-led approach to every project.
From early-stage Passivhaus design and airtight construction through to MVHR commissioning and lifetime servicing — one accountable partner.
Earthwise operates two complementary specialist divisions — bringing the same standard of detail, ecological care and technical rigour to both.
Bristol & South West
Passivhaus new builds, whole-house retrofits and eco design-and-build for homeowners, architects and developers across Bristol and the South West.
Nationwide · England & Wales
Whisper-quiet, super-efficient mechanical ventilation. Bespoke design, expert installation, full commissioning and servicing — anywhere in England and Wales.
"The reason I started Earthwise Construction was because of being fed up with construction being driven for profit, rather than having a long lasting contribution. The work we do always has environmental, economical and comfort sustainability in mind for the users."
— Ben East, FounderEarthwise is values-led from the ground up. We work selectively, only with clients who share our environmental ethos — meaning every project benefits from genuine ecological awareness from design through to completion, and energy efficiency costs that are always recovered through reduced bills.
Eighteen years of green building experience, deep technical knowledge of Passivhaus standards, and the trust of accreditation bodies including the Green Register, Passivhaus Trust and Green Building Store sit behind every project we touch.

Every published review of Earthwise is five stars. Here's what our clients say in their own words.
"Working with Earthwise on our eco-home has been a real treat. Ben and the team have been professional and timely throughout. The whole 1st fix install was done in just 2 days! Our MVHR is whisper quiet and super efficient — we could not be happier."
"We have been delighted with the quality of the MVHR unit recommended by Earthwise — and their advice and guidance regarding the fitting. Their fitter worked very well with the builders. A very helpful and knowledgeable engineer."
"Earthwise are experts in their field — knowledgeable staff, a collaborative approach, and a genuine commitment to sustainable materials and energy efficiency. The improvements to our indoor air quality and reduction in condensation have been remarkable."
