Welcome to Earthwise Construction,
a sustainable building and MVHR company based in Bristol.

With over 18 years’ green building experience, we work with home owners, architects, developers and businesses across Bristol and the South West, offering comprehensive eco-design & build services, and specialising in Passivhaus timber frame new builds and whole house retrofits.

We also have a ventilation arm of the business, specialising in Mechanical Ventilation with Heat Recovery (MVHR) and we design, supply, install, commission and service high-end and mid-range MVHR systems. Discover more in our brochure.

We also supply and install Demand Controlled Ventilation (DCV), which is a fantastic ventilation solution in renovation projects or those where space and/or budget could rule out installing MVHR. 

We offer MVHR and DCV to clients across England and Wales.

In addition, we offer heating and cooling options for eco builds, such as far-infrared heating panels, and we sell a range of products in our online shop, including airtightness products (we’re a Pro Clima stockist), MVHR filters and MVHR components. Clients can arrange to visit our showroom in Bedminster, Bristol, which stocks all these products, and has working MVHR and DCV units.

Minimising environmental impact and maximising energy efficiency is at the heart of everything we do.

What we do

Kind words

  • Ben and his team installed a MVHR system in our new build and they were a pleasure to deal with from start to finish. The workmanship is very high quality and Ben is extremely knowledgeable with these types of systems too.

  • Working with Earthwise on our eco-home has been a real treat. Ben and the team have been professional and timely throughout the project. The whole 1st fix install was done in just 2 days! and the final commission process took just a few hours. Our MVHR is whisper quiet and super efficient! We could not be happier with the results or the way Earthwise worked with us.

  • We have been delighted with the quality of the MVHR unit recommended by Earthwise, and also their advice and guidance regarding the fitting of the unit. Their fitter also worked very well with the builders who were working on the house. A very helpful and knowledgeable engineer.
