Assessment of our building contractors

Construction work at Croome, Worcestershire

At the National Trust we look after special places for ever, for everyone. Our building contractors play an important role in this, by providing the skills and resources we need to deliver projects and maintain our properties.

It's important that all goods, services and works meet applicable legal and industry standards for competency, ethics and environment, financial health, insurance, licenses and accreditations. Our new method of assurance for building contractors ensures that we meet the standards that are expected of us as a leading conservation charity.  

Here you’ll find useful information about the Trust’s standards of assurance, and how to get started. If you're a building contractor, you’ll need to be a fully verified member of Constructionline (Level2 / Silver) and a Health and Safety scheme accredited to Safety Schemes in Procurement (SSIP).  

What you need to do

To start your application process visit the Constructionline website. Before you get started please review the checklist below, making sure you have all the required information and evidence to hand will make the process a lot easier.
