cabling an electric shower

[ban-all-sheds]

do you mean "If you assume a supply voltage of 230 then you have to adjust the ratings of the appliances for 230V, not 240V

If you cannot find a manufacturers rating at 230V buried in the specs then you would have to calculate your own adjusted figure.

Just in response to an earlier post about notifying building control. I'm wondering, do any DIYer's ever actually bother notifying building control? Most jobs DIYer's attempt are pretty simple anyway, which means they don't want to fork out for an electrician to come and botch it up as they usually do in my experience, and don't want to pay the £300 most building controls charge to come and certify the work. Part P is fundamentally flawed, and people will continue to do jobs without notifying until the day they send the electric police round to everyone's houses to check up on their wiring. At which time, we've all died from global warming and turned into vegetables anyways

Goldberg, did you purposely miss my reply on page 2?

I'd love to know what you were getting at

Probably not. We can tell people of what their legal obligations are - what they do with that information is their business.

Many jobs are simple, IF you know what you are doing, and have the correct tools and equipment to do the job.
Most DIY people do not - look at the ridiculous mess people get into with 'simple' tasks such as changing lights and light switches every day on this forum, mostly because they dismantle things without the slightest interest in knowing how they work.

Part P is fundamentally flawed

Quite likely, but any system will have flaws. Corgi (now Gassafe) didn't stop dangerous gas work, and they have had the best part of two decades.
