We would strongly recommend that whoever the contractor is it is always sensible to sign a contract with them in order to ensure that all terms and conditions are clearly laid down at the beginning.  Building work is expensive and it is important that the rights of each party are clearly defined and protected.  

You can download a householder-type agreement from the Master Builder Federation or RIBA websites. Alternatively, we can advise you on the different forms available and administer the chosen contract on your behalf during the build phase of the project.
