Let’s face it — trying to figure out the actual cost of installing an electric shower in the UK can be confusing. One website says it’s £200, another swears it’ll cost you £800. So, how do you know what’s accurate?
It’s always good to have a rough idea of the electric shower installation cost upfront so you’re not blindsided when it comes time to book the work. Whether you’re budgeting for a bathroom upgrade or just replacing an old electric shower unit, it helps to know what you’re in for.
That’s exactly why we’ve put together this no-nonsense guide — breaking down the costs, how to find someone reliable to do the job, and when you might not need a professional at all. By the end, you’ll be fully clued up and ready to make a cost-effective decision that works for your home and your budget.
What Is an Electric Shower (and How Does It Work)?
Electric showers are a popular choice in UK homes, especially where there's low hot water pressure or limited access to a boiler. But what actually makes them different from other types of showers?
In simple terms, an electric shower unit heats cold water on demand using an in-built heating element — kind of like a kettle, but for your daily rinse. This means it only needs access to your cold water supply and not your boiler or hot water tank. Pretty handy, right?
The beauty of this setup is that electric showers work independently from your home’s main water heating system. So, even if your boiler’s playing up, you can still enjoy instant hot water whenever you need it.
It’s an ideal solution if you want a cost-effective, energy-efficient way to stay fresh — especially in homes with smaller water systems or multiple bathrooms.
How to Find a Reliable Electric Shower Installer
So, who’s the right person for the job? Finding a reliable professional to install your electric shower isn’t just about getting the best price — it’s about making sure the work is safe, legal, and up to UK standards.
The best installers are certified under one or more of the official self-certification schemes. These ensure your installer meets the necessary safety and competency standards required for electrical work in the UK. Look out for any of the following:
- BRE Certification
- British Standards Institution
- ELECSA
- NAPIT Certification
- NICEIC Certification Services
You can also check with your local council’s building control team — they often keep a list of registered and trusted tradespeople who meet the proper requirements.
Always ask your installer if they are Part P certified and whether they will provide you with a BS7671 certificate once the work is complete.
This certificate proves that all electrical work has been carried out safely and in compliance with UK regulations. It’s something you’ll definitely need if you decide to sell your home later on.
If your installer doesn’t provide this certificate, you’ll need to arrange for an independent inspection at your own cost. And if the work doesn’t meet building standards, you’ll also be liable for fixing it.
Why Go with a Professional?
Installing an electric shower isn’t just about plumbing — it also involves dealing with electrical wiring. That’s why getting a qualified professional involved is usually the smartest (and safest) move.
Safety First: Electricity and Water Don’t Mix
Let’s be real — electric showers combine two things that should never cross paths without serious care: water and electricity. One wrong move, and you’re looking at a serious safety risk.
That’s why you need someone who knows what they’re doing. A Part P certified professional ensures everything is wired up correctly and safely, with no dodgy shortcuts.
It’s Not Just Smart — It’s the Law
By law, electrical work in your home must meet UK building regulations. That means anyone doing electrical installation work must be Part P qualified — or have the job checked and signed off by your local building control team.
If you try to do it yourself without this, you’ll need to pay for an inspection. And if anything doesn’t meet the required standard? You’ll be footing the bill to put it right.
Save Time (and Maybe Money) with a Dual-Qualified Installer
Here’s something handy — many installers are qualified as both electricians and plumbers. That means they can handle the whole job from start to finish: wiring, plumbing, the lot.
Not only does this cut down on coordination and delays, but it can also help reduce labour costs, since you’re not paying two separate trades to get the job done.
What About Jobs That Don’t Need Part P?
There are a few rare cases where Part P certification isn’t required — like swapping an old electric shower for a new one with the exact same power rating and no need for new wiring. We’ll get into those details a little further down.
But in general? If new cables or circuit changes are involved, you’ll want a certified professional on the job — no question.
Replacement vs New Fitting
When it comes to installing an electric shower, whether you’re replacing an old unit or starting from scratch makes a big difference — not just in terms of labour but in overall cost too.
Replacing an Existing Shower
If you already have an electric shower and you're just swapping it for a newer model with a similar kW rating, you're in luck — this is the easiest and most affordable option.
The wiring and plumbing are already in place, so it’s mostly a case of disconnecting the old unit and fitting the new one. You might need a few adjustments to pipework or brackets, but in general, this type of shower installation cost tends to be lower and quicker.
Expect this kind of job to cost less on both labour and materials, especially if there’s no need to upgrade the electric cable.
Installing a New Electric Shower
Now, if you’re adding an electric shower where there wasn’t one before, that’s a bit more involved.
A new electric shower installation usually means:
- Running new electrical cables from your consumer unit
- Possibly upgrading the circuit breaker
- Connecting the shower to your cold water supply
- Fitting the unit, riser rail, and plumbing connections
Because there’s more electrical work and plumbing involved, this takes longer and pushes the cost higher — both in terms of labour and materials.
So, if you’re starting from scratch, expect to pay more than you would for a straightforward replacement.
Quick Comparison
Type of Installation | What’s Involved | Typical Cost Range (Labour + Materials) |
|---|---|---|
Replacement (same power) | Simple swap, no new wiring or plumbing needed | £200–£400 |
New installation | Full wiring, plumbing, and shower fitting | £400–£800 |
A Breakdown of What to Expect
Let’s talk numbers. How much you'll pay to install an electric shower depends on the type of job, whether new wiring is needed, and what kind of unit you're going for. Below is a handy breakdown of typical labour costs and material costs, depending on the work required.
Electric Shower Installation Cost Breakdown
Job Description | Labour Costs | Material Costs | Total Estimated Cost |
|---|---|---|---|
Replace an existing electric shower (same power, no cable upgrade) | £175 | From £85 | £260+ |
Replace an existing shower with cable upgrade | +£125 | +£50 | £435+ |
Install a new electric shower with no existing wiring or plumbing | £250 | From £150 | £400–£600+ |
Replace a pumped electric shower | £300 | From £85 | £385+ |
Labour costs cover the professional fitting, any electrical or plumbing adjustments, and safe disconnection of the old unit if needed. Material costs usually refer to the shower unit but may also include extra piping, cabling, and fittings — depending on the job.
What About Power Showers?
Even though this guide is all about electric showers, power showers are popular, too, and it’s worth knowing how their costs stack up for comparison.
Job Description | Labour Costs | Material Costs | Total Estimated Cost |
|---|---|---|---|
New power shower installation | £350 | From £150 | £500+ |
Replacement of existing power shower | £120 | From £150 | £270+ |
Worth noting — a power shower installation usually costs more upfront, and running it daily can be nearly double the cost of an electric model. On average, a 10-minute electric shower might cost around 20p, while a powerful shower could be closer to 40p per use.
Want to Save Money?
Here are a few quick tips to cut your shower installation cost without cutting corners:
- Buy the shower unit yourself — installers often charge a markup.
- Choose a unit with the same kW rating as your old one to avoid cable upgrades.
- Get multiple quotes to compare labour costs.
- Go for a model that works with your current cold water supply setup.
Also, remember that electric showers range widely in price. While budget models start around £75, premium electric shower units can go well over £300, depending on brand and features.
Do You Need an Electrician for a Replacement Shower?
Here’s a question a lot of people ask: If I’m just swapping out my old electric shower for a new one, do I really need an electrician? The short answer? It depends.
When You Might Not Need a Professional
If you’re replacing your old electric shower with a new unit that has the exact same power rating, and no changes are needed to the existing electrical wiring or plumbing, then, technically, you can do it yourself.
This is what’s known as a like-for-like replacement, and because there’s no new electrical work involved, you don’t necessarily need a Part P certified electrician. Just unbolt the old one, fit the new one, and you're good to go — as long as you're confident about doing it safely.
That said, make sure:
- The existing cable is in good condition
- The unit is installed in the same position
- No changes are made to the electrical circuit
If you’re even slightly unsure about any of that, it’s worth bringing in a professional.
When You Absolutely Do
If your new shower has a higher kW rating than the old one — even by just a little — or you need to change the cabling, consumer unit, or plumbing, then yes, you’ll need a certified professional.
That’s because the shower installation now involves electrical work that must comply with UK building regulations. Without a Part P certified electrician or a building control inspection, you could end up voiding your home insurance or running into legal issues down the line.
Quick Recap
Scenario | DIY Possible? | Certified Professional Needed? |
|---|---|---|
Same power rating, no wiring changes | Yes | Not required (but recommended) |
New shower with higher power or new wiring | Yes | Yes |
Any changes to the plumbing or electrics | No | Yes |
Even though it might seem tempting to do it yourself and save money, remember — if anything goes wrong, the fix could cost a lot more than hiring someone to do it right the first time.
Frequently Asked Questions About Electric Shower Installation
What Is The Average Electric Shower Installation Cost In The UK?
The electric shower installation cost can vary depending on whether you're replacing an existing unit or fitting a brand new one.
For a simple replacement, you're typically looking at £200–£400, while a full new electric shower installation can cost anywhere from £400 to £800, depending on labour costs, the shower unit chosen, and whether new wiring and plumbing are needed.
Can I Install A New Electric Shower If I Don’t Have A Hot Water Tank?
Yes. That’s one of the biggest perks of electric showers — they don’t rely on a hot water supply or a boiler. Instead, they heat cold water on demand using an in-built heating element, so they’re ideal for homes with limited hot water systems or no hot water tank.
Do Electric Showers Need Both Hot And Cold Water?
No. Electric showers only require a cold water supply. The unit heats water internally, which makes it a popular choice for homes with low hot water pressure or those without access to both hot and cold water lines in the bathroom.
What’s The Difference Between Electric Showers And Power Showers?
A power shower works by boosting water flow from both the hot and cold water supplies using an internal pump. It doesn't heat the water — it just mixes and delivers it with more pressure.
An electric shower, on the other hand, only needs a cold water feed and heats it as needed. It’s more cost effective to run, but usually has a lower flow rate than a powerful shower setup. Also, a power shower installation tends to cost more upfront.
Is A Mixer Shower Better Than An Electric Shower?
It depends on your home’s setup. A mixer shower blends hot and cold water from your existing mains water supply, so you’ll need good pressure and a reliable hot water system, like a boiler or hot water tank. If that’s not the case, an electric shower unit may be more practical.
What Types Of Shower Units Can I Choose From?
There are loads of shower types out there — from basic electric shower units to digital showers with temperature control and advanced features. Some even include built-in shower panels, programmable timers, or LED lighting.
If you’re on a budget, keep it simple. But if you’re after a more luxurious experience, a digital shower or high-end mira shower might be worth the additional costs.
Can Electric Shower Installation Costs Vary Depending On The Property?
Yes, shower installation costs can vary depending on a few key things — like how far the unit is from your electricity supply, whether you need extra plumbing work, or if the installer has to drill through thick walls to reach the water supply.
These small changes can impact the overall cost, so always ask for a detailed quote.
Final Thoughts
There’s no one-size-fits-all when it comes to installing an electric shower. Your installation cost will depend on several factors, from the type of shower unit you choose to how complex the job is. But with the right info — and the right installer — it’s totally doable without blowing your budget.
Whether you're upgrading an old electric shower, exploring other shower types, or going for your first new shower unit, being prepared is the best way to save money and avoid surprises.
