It’s not required, and don’t put a smoke alarm in a kitchen. A heat alarm is what you need.
A system where one alarm sets off all alarms is the best option. I have no idea if Fire Angel make such a thing that inter operates with your existing. I only ever use Aico alarms.
edit, maybe this one.

Really? I didn’t know that. Is that a new building regulation?

Well this just seems silly. Happy to put a hardwired heat alarm in extension but not putting hardwired alarms in rest of house this would mean chopping a few things about etc. Especially when I already have a perfectly functioning system. What are the benifits of a hardwired system? The battery and hardwired systems both seem like they need replacing after 10 years anyway.
I have this system fitted at the moment.

Any new build or extension should have at least one hard wired smoke alarm fitted, I think from 1992 . we had to fit wired ones in our extension part of building regs control.
I only suggested fitting all wired alarms as they are linked and to each other and can give a better warning to people in every part of the property and stops people removing batterys when the are running low

Batteries run down, and when that happens the alarm doesn't work and no one will know unless it's actually tested by pressing the button.
All alarms in a property should be linked together so that the alarm sound can be heard in every part of the property. That can be done with wires, or wireless.
BS 5839-6:2019 covers smoke alarms in dwellings, and while that's not the law, it's the accepted standard that is used.
Battery operated only is the lowest possible grade, and is not recommended for any new installations.

Surely the alarm beeps when the batteries are low, I think Nest sends a text message as well as a voice alert
Definitely sensible - but, as TTC asked, what is the regulation that you think requires this (and has required it, from 1992 or whenever)?

Deserve all they get really
There are many sideways discussions on this "thread", on which I will not comment.
The simple fact is that an interconnected set of photo-electric "Smoke Alarms", powered from the "mains" and each with battery "back-up", in all bed-rooms and living areas is a "good idea".
Rechargeable Lithium batteries in these units are also a good idea - and all units should be replaced after ten years.
(Yes, all of this may be relatively expensive - but what is the cost of a human life, which may be yours.)
This is increasingly becoming "mandatory" in many jurisdictions.
If it is not yet "mandatory" in your "jurisdiction", perhaps it should be.

Requirements for smoke alarms is in Approved Document B, which for fire detection in dwellings mostly just repeats the requirements of BS 5839-6.
Although that is not the only way to achieve compliance with building regulations, it's what building control will accept without argument and what the vast majority of people will use - just in the same way that Approved Document P suggests following BS7671 to achieve compliance.
