The list of notifiable work depends upon which UK country a tiny bit but

 

"12.—(6A) A person intending to carry out building work in relation to which Part P of Schedule 1 imposes a requirement is required to give a building notice or deposit full plans where the work consists of—
(a) the installation of a new circuit;
(b) the replacement of a consumer unit; or
(c) any addition or alteration to existing circuits in a special location.

Thank you for sharing. 

We employed a reputable NICEIC firm to replace our consumer unit. Not only did they not give any building notice but they tried to evade the requirement to issue us with the electrical certificate! 

My conclusion is that, if they did not notify a CU replacement, they are very unlikely are they to notify a new circuit. This seems to be standard practice. 

Unfortunately this section of the Part P does not mention batteries, will need to do some more digging. To be clear, I also expect most of the work needs to be done by an electrician. What I am not clear is whether the electrician needs a special qualification for battery work (and I mean NICEIC or NAPIT, not MCS). 

As of October 1st they need specific qualifications to do solar, EV charger or battery work. It was changed in EAS 2024.

There's now a new regulators gravy train, sorry I mean training requirement for

- Performing an EICR (presumably it's "how not to get caught doing it over the phone")

- EV charging

- Solar PV

- Electrical Storage Systems

The Sparx I know all think it's yet another money grab or would I suspect agree with you that professional bodies are useless on enforcement and just want to make money on an endless qualification gravy train. On numbers we are going to have a serious shortage of sparkx in a few years. The older ones are throwing in the towel with the infinite money pit caused by the regulators and the newer ones simply aren't bothering with the qualifications needed to self sign.

The more interesting part though in all of this is that the SEG guidance for licensees says

3.3.At a minimum, a SEG licensee must offer one SEG tariff that is available to all SEG-
eligible installations

4.1.A SEG licensee is only required to accept a request for SEG payments if the
installation meets the eligibility requirements detailed in this chapter.

4.6. For PV, wind and micro-CHP installations up to 50kW, generators should
demonstrate that the installation and installer are suitably certified. An applicant
may have an installation certificate to demonstrate this. This may be a
Microgeneration Certification Scheme (MCS) certificate, but the SEG recognises
other schemes may be equivalent to MCS.

4.7.The SLCs define an equivalent scheme as a scheme accredited in accordance with
EN 45011 or EN ISO/IEC 17065:2012.

4.7 if you turn it into plain English almost certainly means any electrician now qualified to install your battery is qualified in accordance with 4.7 so what happens when this gets tested a bit more and the MCS get cut out will be entertaining.

With battery-only storage, the tariff spread is only part of the calculation. Check round-trip efficiency, standing charges, inverter limits, export permissions and whether the product is plug-in or hard-wired. This is a general battery/inverter matching checklist, not a substitute for UK DNO or wiring advice.
