Can I add my own clauses?

All legally required clauses will be included in every tenancy agreement, but landlords can also add additional clauses if they want to. The Digital Contract Maker provides a list of common clauses to choose from. These clauses are optional and refer to things specific to the property, such as gardens and outdoor areas, bins and storage and alterations to the property. 
Landlords can also add custom clauses. This is an advanced option and comes with the risk that they will not meet best practices. Custom clauses must be reasonable and written in plain, transparent language. If a clause is proven to be unfair, it cannot be enforced and will not be legally binding.
