Vaillant Boiler Prices Range From £800to £2,800
Vaillant isn’t the cheapest boiler brand on the market. I’m sure you’ve seen other brands offering gas boilers for £500 or less — probably for a budget 24kW boiler brand, with a 2-year warranty at best. Well, none of the boiler prices below can compete with that, andthere’s a reason for it.
Much like Worcester Bosch, Vaillant is a premium boiler brand. They focus on efficiency (and therefore, savings on energy bills), reliability, practicality and warranty.
All those things come at a price.
The price range above includes system, regular, and combi boilers of various capacities. We’ve got an ecoTEC Plus 12kW system boiler on the lower end, just shy of 800 quid; its mighty 64 kW counterpart at £2,800; and everything in between.
If you’re looking for the average 24kW combi — for which we’d recommend the ecoTEC Pro 24kW — you can find a new gas boiler for about £950 (remember: this excludes installation).

How Much Is a Vaillant Boiler?
To offer you a simple price comparison, we’ve drawn up the tables below for Vaillant’s combi, system, and open vent boilers. The prices range based on the output rating (noted in parentheses in the table).
Vaillant Combi Boiler Prices
|Vaillant Combi Boilers||Cost|
|ecoFIT Pure Combi (25kW – 35kW)||£860 – £1,120|
|ecoTEC Pro Combi (24kW – 30kW)||£920 – £1,820|
Vaillant Regular Boiler Prices
|Vaillant Regular Boilers||Cost|
|ecoFIT Pure Regular (12kW – 35kW)||£740 – £1,450|
|ecoTEC Plus Regular (15kW – 38kW)||£800 – £1,440|
Vaillant System Boiler Prices
|Vaillant System Boilers||Cost|
|ecoFIT Pure System (12kW – 35kW)||£940 – £1,250|
|ecoTEC Plus System (15kW – 38kW)||£880 – £1,480|
Unless your household has excessive hot water demand (think 3 showers running at once), your best pick should be one of the ecoTEC Pro combination boilers; these should give you a sufficient flow rate.
However, if you do require lots of hot water — think 3 showers running at once — a regular or system boiler may be a better option.
Note that system boilers will require a hot water cylinder to function, whilst regular boilers also need a cold water tank.
Vaillant Boiler Warranties
This Vaillant range comes with a 5-year warranty as standard, and we’d not recommend installing a boiler with any less than this.
Although the cost of a Vaillant boiler with a 5, 7 or 10-year warranty will be more (£150-300) than a lesser brand offering just 2 years, the longer coverage is worth the extra pound notes.
That’s because if you have to replace your boiler 2-years down the line rather than after a decade, you’ll be out of pocket in a big way.
There’s the option to upgrade the Vaillant ecoTEC Plus to a 7 or 10-year warranty when using a Vaillant Advance Installer.
That’s comparable to Worcester boilers, which come with a 10-year warranty.

Vaillant Boiler Installation Costs
The cost of a Vaillant boiler itself is only a small piece of the puzzle.
The largest portion of boiler installation costs is made up of labour and materials the Gas Safe boiler engineers require to facilitate the setup.
As a rough guide, adding around £1,000 for materials and labour won’t steer you too far wrong.That will add up to TOTAL installation cost of around £2,200 for a Vaillant ecoTEC Plus 24kW.
That said, there are plenty of other factors that can cause the costs to fluctuate. For instance:
- Is a magnetic system filter being fitted? This could add £150-250 to the cost of your new Vaillant boiler.
- Does the boiler need to be moved to a new location? This could add £350-750 to your quote.
- Is your flue installed horizontally or vertically? The latter variation typically costs more.
- Where do you live in the UK? London tends to be the priciest, but costs do vary between the other 8 regions, too.
The list goes on.
That’s why we suggest you try using Heatable’s calculator to get FIXED boiler quotes on a range of boilers suitable for your property. You don’t have to provide any personal details, and the whole thing takes 90 seconds.
How Vaillant Boiler Prices Compare to Worcester Bosch
As you can see from the chart below, you can get a Worcester Bosch boiler of an equivalent output to the Vaillant combi range for roughly the same price.
Remember, these costs don’t include installation and still hinge on all the factors we discussed above.
Heatable is a national boiler installation company that installs the best boiler brands like Worcester Bosch, Viessmann, Ideal, and others. Because of their size, naturally, they get Worcester boilers well below what most installers can.
And looking at the fixed prices online, that converts to installation prices that are around £200-300 cheaper than expected.
To get an example, you can useHeatable’s calculatorto get a fixed-price quote on a Worcester Greenstar 4000 — the most comparable alternative to Vaillant’s ecoTEC Pro Combi 30kW. You’ll also see a range of other boiler options that are suitable for your property.

Upgrade Or Repair Your Boiler
If you’re on the fence about replacing your boiler, there are a few things to consider.
Boiler Efficiency Rating
The first is what efficiency rating your boiler is. Modern boilers are A-rated, typically being 89% efficient or more.
For instance, the EcoTec Plus is 89.3% efficient.
The oldest boilers can be less than 70% efficient. With heating bills making up around 55% of utilities, that’s a lot of cash to be flushing down the drain.
Another thing to consider is the overall condition of your boiler. We’ve written a guide covering average boiler repair costs, and in general, such repairs are not cheap.
If your boiler is deteriorating, it might be worth considering a replacement over a repair.
Typically, a replacement is going to be a good option if your boiler:
- Isn’t A-rated
- It is out of warranty
- Needs £500+ worth of repairs
- Has been given a general health check by a Gas Safe engineer, indicating that the PCB, gas valve, fan and pump are in poor condition.
Anything less than this, and repairs are likely to be the better option.
FAQs About Vaillant Boiler Prices
Below, we’ll answer some questions we often get about Vaillant boilers.
Are Vaillant boilers expensive?
Vaillant boilers are not cheap — they’re typically a bit pricier than equivalents from Worcester Bosch or Viessmann.
Boiler-only costs range between £800 and £2,800, whilst a complete installation by gas engineers will set you back anywhere between £2,100 and £4,000.
What is the life expectancy of a Vaillant boiler?
You can expect a Vaillant boiler to last 10 to 15 years, given proper maintenance and annual boiler service.
To make sure that your Vaillant boiler lasts as long as possible, you should equip the central heating system with limescale and magnetic filters, which help keep the system free of limescale deposits and sludge build-up, respectively. Both of the latter can accumulate over time and damage the boiler.
Annual boiler service is another must — it allows a Gas Safe boiler engineer to identify boiler problems early, before they deteriorate.
How much does a Vaillant ecoTEC Plus cost?
A Vaillant ecoTEC Plus (24kW) costs roughly £1,400 if you’re getting the boiler only.
Together with installation, you can expect to pay around £2,400; the total cost may differ, depending on:
- Which extras you get
- Which boiler installers you use
- Your roof configuration and flue type
- Which part of the UK you call home
The list above is not exhaustive.
Is Vaillant a good make of boiler?
Vaillant are one of the best boiler manufacturers available in the UK. The company have been around for over 140 years, and remain a respected, well-known manufacturers of quality, efficient boilers.
Is a Vaillant better than a Worcester boiler?
Worcester Bosch and Vaillant are both highly reputable, “top-shelf” boiler brands. Boilers from both brands are efficient, quiet, and known to last long.
Where Vaillant has a slight advantage over Worcester is in the heat exchanger materiality. Whilst Worcester’s heat exchangers are made from aluminium, Vaillant boasts stainless steel heat exchangers — these are known to more resistant to corrosion and wear-and-tear.
That being said, you can get a longer warranty when opting for a Worcester with Heatable’s installation. Doing so gets you 10 years, whilst Vaillant’s standard warranty is 5 years — or 7 years if the installation is registered by an advance installer.
