i3 Studios offer a five year structural warranty. However, certain individual elements are subject to the terms of the manufacturer’s guarantee only (up to 20 years).


We are accredited members of IWA, who are one of the leading organisations in the UK to administer deposit protection and guarantee insurance to consumers within the home improvement market.

This means for an additional sum, we are able to offer a 10 year insurance backed guarantee on all of our outdoor studios projects, as well as protect your deposit in the unlikely event we were to cease trading. For further details on this scheme, please enquire with a member of the team.

Once the deposit is paid we instruct an independent building inspector. We give them a full set of plans, cross sections and structural calculations for them to check and approve. We also fill in a project information and appointment form, giving them the schedule of works, and when we will be starting, so the building inspector can coordinate visits to check on the build, normally without warning.

Once the Outdoor studio is completed they will have one final inspection, and then the building inspector will issue you a Final Certificate – this will be a valuable asset to have if you ever decide to sell your home.
