If you’re looking to install a new electric shower, you may be wondering whether you should call a plumber or an electrician. A plumber will be well-equipped to handle the water supply connections and pipework you will need for your new shower; however any electrical work should always be carried out by a Part-P qualified tradesperson.
This Part-P qualified tradesperson will need to be able to:
- Assess your current electrical system to ensure it can handle the additional load of the shower.
- Choose the correct cable size for the shower’s power rating.
- Have access to the equipment needed to test new electrical equipment and installations.
- Correctly fill out an electrical test certificate for the job.
- Safely connect the shower unit to the electrical supply.
- Test the installation to ensure it functions safely.
- Inform the local building authority control to let them know that electrical installation work has been carried out in a room containing a bath or shower.
In summary, you will need to find either a qualified electrician or a Part-P certified plumber to install your electric shower, as they will be trained in both the plumbing side of the installation and qualified to do the electrics.
This is essential due to the dangerous combination of water and electricity that this job involves; hiring someone that is not experienced or qualified for the job will not only be hazardous but will ultimately cost you a hefty sum for repairs in the future.
Do you wish you could install your electric shower yourself? Why not considering changing careers and training as an electrician?
Access Training offer a number of bespoke electrician courses to people of all ages and backgrounds. With qualifications including general installation, Part P training, PAT Testing and more, we're certain we have the right electrical course for you.

Is the popularity of a good relaxing bath in decline?
A new study from online bathroom retailer UK Bathrooms seem to think so, as their research has found order trends and customer feedback for baths has had a 54% decrease in the last year. On the other hand, the popularity of showers seems stronger than ever which has seen a staggering 72% increase. The study even found that three quarters of British homeowners would choose to install a shower in their home over a bath.
The survey looked at 1342 homeowners in the country, and was part of ongoing research into the opinion about bathroom styles. Respondents were also revealed the reasons why they considered showers to be superior to baths - 46% considered it much quicker, while 34% also added that a shower left them feeling much cleaner than a bath did.
Moving on to bathrooms themselves, 40% of respondents only had showers in their bathrooms, with 28% only having a bath and 32% owning both. If they were to move or renovate their bathrooms, 78% said that installing a shower was of much higher priority than a bath. Why? 51% considered showers to be the speedier option, while 37% also preferred it because showers take up much less space than a bathtub.
Whether you're a bath or shower person (or both!), the winner here is still bathroom installers and plumbers in general. Whether your customer wants a shower or bath (or again, both!) installed, a fully qualified plumber is the only man for the job. If you're interested in specifically going into bathroom fitting, Access Training also offer specialised bathroom fitting courses to provide trainees with everything they'll need to know to perform the job to a professional standard.

Firstly when you’re having problems with your electric shower don’t attempt to fix it, this is false economy – you’re much better off changing the item completely. Here are a few steps to show you how to change an electric shower.
- Step One - Safely take off the front cover of the electric shower box. There will be at least 1 or possibly 2 small screws holding this in place. Next, take off the front temperature and control knobs by pulling them straight off (this shouldn’t be too difficult to do). With the front cover off you should be able to see a valve on the water pipe going into the shower unit, it should have a screw slot in the middle of the valve. Turn this a ¼ turn either way and test the shower to see if this has turned off the water. You can use the control knob by temporarily re-attaching it to the shower to get the water to flow.
- Step Two - When changing an electric shower, you must turn off the electric supply at the consumer unit (or fuse board as it’s commonly known). The fuses/trips should be marked but if they’re not, the 1 of 2 possible trips you are going to turn off will be either a 35 amp or a 45 amp depending on the Kilo-watt power of the shower. For a 35 amp fuse/trip, the shower should not be over 8.5 kilowatts. For a shower that is greater in kilowatts, the fuse/trip will be a 45 amp.
- Step Three - The next step in changing your electric shower is to check that the electric has been turned off by either pulling the cord switch in your bathroom or the wall-mounted one outside. Run the shower and make sure that the running water isn’t warm/hot. With the electric turned off, you can put a notice hanging from the consumer unit to warn others not to turn back on.
- Step Four - If the water is now off you can take off the water connection where it connects closest to the unit. Undo the electric cable connections and remove the unit, remembering to replace like-for-like in the kilowatt power rating of the unit (this rating can be found somewhere on the old unit, and on the front cover box of the new one).
- Step Five - When you have connected the new unit to the electric cable and to the water supply, check the water flow through the unit first, then with the cover on the unit you can turn the electric fuse/trip back on. Go back to the unit and turn the wall-mounted switch or pull the cord on, turn up the thermostatic control on the unit and the water control knob to on. Your new shower should be working, but with the new shower unit you will have the manufacturer’s instructions in the box. Follow these carefully, and it should be safe for you to install.
