building control who is responsible
Building Control Sign-Off: Is the Tradesman or Homeowner Responsible?
By default, the building owner is legally responsible for making sure notifiable work gets building control approval - not you. But there's a big exception: if you're registered on a competent person scheme, notifying your own work is your job, and nobody else can do it for you. Most of the grief happens in the gap between those two rules - usually years later, when the house goes up for sale.
The default rule: the owner carries it
Building regulations responsibility sits with the building owner. Structural openings, new drainage, the loft conversion as a whole - it is the owner who must make sure building control is involved and the work gets signed off. If they never applied and never told anyone, that failure is legally theirs, even though you swung the hammer. It is also their problem to fix later, which is precisely why you want your own position recorded in writing while everyone still remembers the job.
Competent person schemes flip it for your work
Registered installers on competent person schemes - Part P electricians, Gas Safe engineers, FENSA window firms, HETAS stove installers - must self-certify their own work and notify it through their scheme, which then issues the compliance certificate. That duty is yours and yours alone: the owner can't do it for you, and if you forget, it's your name on the failure. It's the trade-off for not needing a building control officer on every job.
Where it surfaces: the house sale
Unnotified work rarely causes trouble in year one. It causes trouble in year four or five, when the house sells and the buyer's solicitor asks for certificates that don't exist. Suddenly there's a panicked owner on the phone, indemnity insurance being argued over, and a sale wobbling - and everyone's memory of who was meant to notify what has gone conveniently hazy. The trade who can point to a lodged notification and a dated certificate is out of the conversation in one email.
Hand over the rest formally
The fix is one paragraph in your terms and on your final invoice: state exactly which notifications you are making, and that everything else belongs to the owner. Quotato lets you drop standard wording like this onto every invoice, so it never depends on you remembering.
Building regulations note: the electrical installation work on this job is being self-certified and notified by us under our competent person scheme - your compliance certificate will be emailed to you within 30 days. All other building control approvals, including sign-off for the structural opening, remain the responsibility of the building owner. We recommend confirming completion sign-off with your local authority building control before the property is next sold.
That wording does three things: it proves you notified what was yours, it puts the owner on written notice of what remains theirs, and it dates the whole arrangement. When the year-four phone call comes, you forward one document and you're done.
From the tools: A window firm my brother subbed for fitted eleven units on a renovation and - one admin slip - never lodged the FENSA notification. Four years later the house sold, the buyer's solicitor asked for certificates, and there weren't any. Sorting it retrospectively cost the firm around £300 in fees, a genuinely fraught week, and very nearly cost the seller the sale. Since then they log the notification the same day as the install, and every final invoice states exactly which certificates are coming and when. One sentence on an invoice, and the year-four phone call becomes a thirty-second email with an attachment.
