Who tells building control that the job is done?

If you are registered with an authorised competent person scheme, you do, through the scheme, instead of going to building control for approval first. GOV.UK describes the schemes as letting installers self certify certain types of work, with no building control fee for the customer.

The two routes, and why most firms take the second #

Building work that falls under the Building Regulations needs approval. The traditional route is a council building control department or a private inspector. The other route is a competent person scheme, which GOV.UK describes as allowing building trade installers to self certify certain types of work rather than obtaining building regulations approval, with customers benefiting "from lower prices as there are no building control fees".

Which scheme covers which work #

GOV.UK publishes the current list of authorised schemes and what each may certify. The ones most relevant to small installers:

SchemeWork it covers
FensaReplacement windows, doors and rooflights
Gas Safe RegisterGas appliances
Certsure, trading as NICEICElectrical and multiple trades
NAPITElectrical and multiple trades
CompetentRooferRoof coverings
HETASSolid fuel and heating
APHCPlumbing and heating
ATTMAAir tightness testing
The full list of work categories across the schemes

Work categories across the schemes include cavity and solid wall insulation, gas, oil and solid fuel combustion appliances, electrical installations in dwellings, heating and hot water systems, plumbing and water supply, replacement windows, doors and rooflights, roof coverings and microgeneration.

For electrical work in dwellings specifically, when notification is required is set out in Approved Document P, which GOV.UK describes as the Building Regulation in England covering electrical safety in dwellings.

Where the admin actually lands #

The notification itself is usually the easy part, because the scheme provides the route. The cost is in what surrounds it, and it has a particular property: it arrives after the money is in, when everybody has moved on to the next job.

Runs on rules

  • Recording the address, the work type and the date it completed
  • Submitting the notification within the scheme's own rules
  • Knowing which finished jobs have not been notified yet
  • Getting the customer their copy
  • Finding a certificate for a job from four years ago, if it was filed against the address

The third of these is the one worth pausing on, because almost nobody has that list.

Needs the competent person

  • Deciding whether this job is notifiable at all
  • Deciding what to do when a job was never notified, which is a conversation with the scheme

In most firms the notification happens because an engineer or an office manager remembers, which means the list of jobs waiting to be notified exists only as an absence.

The double keying underneath it #

There is a pattern that shows up in every trade that certifies its own work, and nobody calls it automation. They call it putting it in twice. The address, the customer, the work description and the completion date get captured five times over.

  1. When the job is booked

  2. Again on the job sheet

  3. Again on the certificate

  4. Again in the scheme portal

  5. Again on the invoice

Each retyping is a chance to introduce an error into a document that will be read years later by a solicitor. It is the same pattern the Department for Education named in its own workload review as re-entry of data into multiple systems, and that letting agents report when 61 per cent say staff transfer or duplicate information between systems.

It crosses every sector we look at because it is not a sector problem, it is what happens when several systems each need the same five facts.

What the customer should end up with #

Whatever the scheme requires for that work type, in a form the customer can find again. That last clause is doing real work. A certificate emailed as an attachment to an address the customer has since stopped using is, for practical purposes, not issued.

Firms that treat the customer copy as the last step of the job rather than an afterthought get noticeably fewer calls in the years afterwards, and a noticeably easier time when a conveyancer comes asking.

The two trades with statutory distribution deadlines of their own are covered on electrical certificates and EICR deadlines and landlord gas safety records. To put hours against your own certificate cycle, start with the which tasks run on rules.

Questions people ask

What is a competent person scheme?
GOV.UK describes it as a scheme that lets building trade installers self certify certain types of work instead of getting building regulations approval from a council or a private inspector, with the customer benefiting from lower prices because there are no building control fees.
Which schemes cover which trades?
The GOV.UK list of authorised schemes includes Fensa for replacement windows, doors and rooflights, Gas Safe Register for gas appliances, Certsure trading as NICEIC and NAPIT for electrical installations in dwellings, CompetentRoofer for roof coverings, HETAS for solid fuel, and APHC for plumbing and heating.
What does an installer have to do to stay in a scheme?
GOV.UK states that installers are assessed for competence before approval and then face ongoing inspections, yearly for the first 2 years, to make sure they continue to meet the standard.
Does the customer need anything after the work is done?
Yes, and it is the part firms get chased about years later. The customer needs the record that the work was certified, because it is what a conveyancing solicitor asks for when the property sells. Which document that is depends on the scheme and the work.
