Certain installation or extension jobs in the home are required to be notified in line with Building Regulations by a member of a Competent Person Scheme. This means that a tradesperson has been properly approved to offer installation and maintenance services to members of the public. Members of Stroma Certification's Competent Person Scheme have the ability to self notify their installation work which saves their customers both time and money. When hiring a tradesperson you should always ask to see their identification to ensure they are a member of a formal certification scheme. This can be either an ID card or a membership certificate.
If you have hired a Stroma Certification member then you can contact Stroma to verify their membership by completing our online form.
It is important that to check whether any installation work undertaken in your property requires approval from Building Control. There are consequences if you do not:
Without Building Control approval a potential buyer for your property may not wish to proceed with the purchase, their mortgage provider may not lend against the property and you might also encounter problems with the conveyancing solicitor that can also prevent a sale.
If you’re hiring an external contractor for installation work, they will be able to advise you whether the job is notifiable. If they are a member of a Competent Person Scheme, your installer will be able to self-certify that work. You can also still use a competent person for non-notifiable work.
