We tested the market leaders for ease of installation, water flow, and reliability. From Triton to Mira, here are the electric showers that actually deliver a decent wash.
In 2026, with energy prices in the UK remaining unpredictable, heating a whole tank of hot water just for a quick 5-minute wash feels like a waste. This is why electric showers remain a staple in British bathrooms. They heat water on demand, taking it directly from the cold mains supply and passing it over a heating element.
The result? You only pay for the hot water you use, and you never run out. But not all electric showers are created equal. Some offer a pathetic dribble, while others use clever “Airboost” technology to mimic a power shower. Whether you are replacing an old yellowing box or installing a new en-suite, we have curated the definitive list of recommended models.
Electric showers are rated in kilowatts (kW). The higher the number, the more powerful the heating element.
Also, consider your water system. If you have a gravity-fed system (cold water tank in the loft) with very low pressure, a standard electric shower won’t work. You need a pumped solution. Check our guide on the best electric showers for low water pressure if this sounds like you.
The T80 lineage is legendary in the UK plumbing world. The T80gsi is the modern evolution, specifically designed to replace almost any existing shower without needing to drill new holes or re-tile.
It features a “Swivel-Fit” water inlet that can swing left or right to meet your pipes, and a massive footprint that covers old screw holes. For those who remember the classic T80Z, this is the worthy successor. You can read more about the history of this range in our Triton T80Z review archive.
If you hate the weak dribble of standard electric showers, the Mira Sport Max is the solution. It features unique “Airboost” technology which forces air into the water stream.
This increases the flow volume sensation by up to 30% without actually using more water. It feels powerful, robust, and invigorating. Mira also includes “Clearscale” technology which reduces limescale build-up by 50%—a must-have if you live in a hard water area like London or the South East.
Sick of chunky white plastic boxes? The Bristan Bliss 3 brings electric showering into the modern era. It features a sleek black or white glass-effect front with a digital temperature display.
The touch controls are intuitive, and the digital readout ensures you know exactly what temperature the water is before you step in—no more freezing arm test! It also includes a phased shutdown to flush out hot water, preventing limescale buildup.
Warning: This is for gravity-fed cold water tanks ONLY. Do not install on mains pressure.
If you have low water pressure from a tank in the loft, a standard electric shower will just dribble. You need a pumped unit. The T90sr is the market leader because it is “Silent Running.” Older pumped showers sounded like a jet engine; this one is so quiet you can hear the water hitting the floor over the noise of the pump.
For those who want precision, Aqualisa is the go-to brand. While they are famous for their digital mixer showers (see our guide on the best digital showers for combi boilers), their electric range is equally impressive.
The Quartz Electric features a simple push-button start and a smooth temperature dial. The internal logic ensures very stable temperatures even if someone flushes a toilet elsewhere in the house. It’s safe, stylish, and incredibly reliable.
Installing an electric shower in a bathroom counts as “special location” work under Part P of the UK Building Regulations.
Triton and Mira are widely considered the most reliable brands in the UK due to parts availability and build quality. The Mira Sport Max and Triton T80 series have proven track records for longevity.
Based on 2026 energy prices (approx 28p/kWh), a 10-minute shower with a 9.5kW unit costs roughly 44p-50p. While electricity is expensive per unit, you save money because you aren’t heating a whole tank of water.
Not always. A 10.5kW shower usually requires a 10mm² cable and a 45A fuse. An 8.5kW shower often runs on a thinner 6mm² cable. If you put a powerful shower on a thin cable, it can overheat and cause a fire. Always have an electrician check your cable size first.
Yes, but they don’t use the boiler at all. They connect to the cold mains pipe that feeds the boiler. This makes them a great backup; if your boiler breaks down, you can still have a hot shower.
