What Are Typical Vaillant Boilers Prices [and should you buy a Worcester instead]?

Welcome to our 10-minute guide to Vaillant boiler prices, and what they cost to install.

If you’re looking for a new boiler, there’s a good chance you’re tossing up between a few brands. And, if you’re like the majority of UK homeowners, you’re trying to make a decision between Baxi, Glow-Worm, Potterton, Worcester Bosch and of course, Vaillant.

At my time working in a plumbing merchants, Vaillant and Ideal Boilers were similar in popularity, with Worcester Bosch being the clear leader.

Vaillant Boilers Prices

So, how much does a Vaillant boiler actually cost? I’m sure you’ve seen boilers as low as £500, that would be for a budget 24kw boiler brand, with a 2-year warranty at best. And, none of the boiler prices mentioned below are going to be able to compete with that.

Why? Much like Worcester Bosch, Vaillant are a premium boiler brand. They focus on efficiency (and therefore, energy savings), reliability, practicality and warranty. All those things come at a price.

Below we’ll look at Vaillant EcoTec Plus boiler prices. 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 is going to be more (£150-300) than a lesser brand offering just 2, it’s worth the extra pound notes.

Around 50% of the installation cost is made up of the boiler itself; the rest is labour and parts. So, if you have to replace your boiler just 2-years down the line rather than 10, you’re 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. You can check prices for those here.

The EcoTec Plus is also comparable to a Worcester Bosch boiler we’ll mention below. These prices don’t include the cost of installation.

Boiler Cost
EcoTec Plus 25kw £1,100
EcoTec Plus 32kw £1,250
EcoTec Plus 35kw £1,320
EcoTec Plus 38kw £1,400

How Vaillant Boiler Prices Compare To Worcester Bosch

As the Vaillant EcoTec Plus isn’t a compact boiler, you won’t be able to install it into a standard sized kitchen cupboard. And the same goes for the comparable range from Worcester; the Greenstar I.

Boiler Cost
Greenstar 25I £950
Greenstar 30I £1,100
25SI Compact £1,100
30SI Compact £1,175
28CDI Compact £1,150
32CDI Compact £1,250
36CDI Compact £1,400
29CDI £1,200
34CDI £1,300
38CDI £1,400

As you can see from the chart above (taken from our Worcester boiler costs page), you’ll get an equivalent output Worcester Bosch boiler, for around £100 less than current Vaillant boiler prices.

You can get a fixed price online on Heatable for a Worcester, and compare that with quotes from local installers on a Vaillant.

Vaillant Boiler Installation Costs

But, the cost of a Vaillant boiler, is only a small part of the puzzle. The majority of boiler installation costs are made up of labour, as well as materials.

For example, a typical installation is going to require copper fittings and copper pipe; that’s a given. But, there are lots of other things that can affect the cost of installation.

Is a magnetic system filter being fitted (advisable)? This could add £150-250 onto 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.

The list goes on. We’ve detailed a range of things that can affect the cost of your new boiler here.

But you can get quotes from local installers on Vaillant boilers here, and a fixed price on a Worcester from Heatable here; compare the two to get the best deal.

How Much Do Labour And Materials Cost For Vaillant Boiler Installation?

As a rough guide, adding on around £1,000 for materials and labour won’t steer you too far wrong.

That’s going to correlate to a installation cost of around £2,100 for a Vaillant EcoTec Plus 24kw.

How Vaillant Boiler Installation Prices Compare With Worcester Bosch Prices

All told, you’d expect to pay anywhere from £2,100 (Vaillant EcoTec Plus 24kw), up to around £2,400 (Vaillant EcoTec Plus 38kw) including all materials and labour.

Based on our price guide, you’d expect Worcester Bosch prices fitted, to be around £100 cheaper. However, that’s changed recently.

Heatable is a national boiler installation company who installs the best boiler brands like Worcester Bosch, Viessmann, Ideal. 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 around £200-300 cheaper than expected.

As example, we plugged in some details to get a Worcester 30I installed for as little £1,649 including VAT. No need for home visits, quotes, phone calls; the prices are all fixed and online.

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 lower than 70% in terms of efficiency (source). With heating bills making up around 55% of utilities, that’s a lot of cash to be flushing down the drain.

Boiler Condition

Another thing to consider, is the overall condition of your boiler. We’ve written a guide covering average boiler repair costs, and in general, they’re 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:

Anything less than this, and a repair is likely to be the better option.
