Data Warehouse

The Data Warehouse has been built following the Each Home Counts review to act as the industry facing repository of information about work undertaken that improves the energy efficiency of domestic dwellings.  You can find out more information about the 27 Each Home Counts recommendations by visiting here

Through combining knowledge and best practice, lodgement aims to support getting installations right first time, reduce the risk of ‘Phoenix’ companies and provide industry insights.  All aimed at supporting businesses, not penalising them.

Select ‘Address Not Found’ and you can manually input the address of the property.

We have created simple short codes to simplify the entry of details about the work completed. This will be particularly helpful for businesses that undertake the same sort of work on a regular basis.

Please visit the TrustMark Data Dictionary, to find the list of work codes.  If you cannot find what you need, please contact support@trustmark.org.uk

You can only lodge works that are relevant to your registered trades.  You can contact your Scheme Provider to talk about increasing your TrustMark scope.  Contact support@trustmark.org.uk, if you need further help.

You can only lodge work that you were TrustMark registered for at the time the work was completed.

Works should be lodged on completion and within 20-working days. However, please ensure that you comply with any lodgement requirements that you are contractually obligated to through either your scheme or supply chain. This also ensures that your customer receives the lodgement certificate in a reasonable timeframe.

The information we hold on your trades is provided by your Scheme Provider – if you would like to expand your TrustMark scope, please contact your Scheme and discuss how they can support this.

You may have businesses or installers that you have worked with many times and are confident in their delivery.  If the contract is between yourself and your customer, then you have ultimate responsibility for the works.  If, however, the sub-contractor will enter into a separate contract with the client, then this sub-contractor must also be TrustMark registered.  You can find out more information in the TrustMark Code of Conduct and Customer Charter.

When lodging work undertaken by a sub-contractor their TrustMark license number must be provided, a check is undertaken to ensure that the sub-contractor was TrustMark registered for the work type when the work was undertaken.

A Retrofit Coordinator will assign your role and send you an invite to add your information, reports or guarantee documents to the works.  The Data Warehouse is accessed through your TrustMark Business Portal.
