The 6 Best [And Most Efficient] Boiler Brands To Install In 2019

Welcome to our 5-minute guide to the best boiler brands.

Installing a new boiler is not cheap. A typical combi could cost £2,000-£3,000 including labour.

And, oil boilers tend to be much more expensive.

So, picking the best boiler brand is the first part of upgrading your central heating.

The Best Combi, Regular & System Boilers

We’ve split this guide into two sections.

Most manufacturers will make combi, regular and system boilers that are powered by gas or LPG.

If yours is powered by oil, we’ve listed 3 of the best oil brands at the end of the article.

#1 – Worcester Bosch

#1 on our list is certainly the most well known.

Worcester Bosch are considered by many to be the best boiler brand available.

They offer boilers in all shapes and sizes:

  • Oil
  • Combi
  • System
  • Regular

They’ve had great success with models like the CDI and a Greenstar 25I/30I. The warranty ranges from 5-10 years.

And, the exact warranty depends on the boiler you choose, and the other Worcester branded products you use.

For instance, adding a Worcester Bosch system filter, will add on a further year’s warranty.

Price Comparison

Worcester Bosch boiler prices USED to be among the most expensive, comparable to Baxi and Vaillant.

However, Bosch have recently made a sizable investment in online boiler installation company; BOXT.

By using a steamlined online sales process (basically, a 90 second multiple choice), and boilers being supplied dirt cheap from Bosch; this is one of the cheapest ways to get a quality boiler installed.

You can check out their prices, by using their online boiler price calculator. It takes around 90 seconds, and no personal details are needed to get your price.

#2 – Ideal Boilers

Ideal Boilers are a British manufacturer that have grown exceptionally over the last decade. They now sell over 10,000 units per year. 

Unlike Worcester, their warranty isn’t confusing.

Ideal offer warranties that are:

  • 2 Years – Ideal Logic
  • 7 Years – Ideal Logic Plus
  • 10 Years – Ideal Vogue (when fitted with a Ideal system filter)

Price Comparison

Ideal Boilers are generally the odd one out. They are heading for being known as a premium brand, but they sit in the mid-range in terms of price.

The boilers that rival Worcester Bosch, tend to be 10-15% cheaper when using a local installer. Of course, with BOXT being so cheap when it comes to Worcester boilers, they tend to work out at around the same price.

#3 – Vaillant

Vaillant are up with there with the best. Most recently, their EcoTec range has become their most popular product line. 

They don’t have the branding behind their company that Worcester does, but the support network is there.

They offer great warranties and a service team to help with problems, for boilers that are under warranty.

Generally, their products have a 2, 3 or 5 year warranty attached to them.

Price Comparison

Expect Vaillant boilers to be in a similar price bracket to Worcester Bosch, Ideal Boilers and Baxi’s equivalent products.

#4 – Potterton

Potterton don’t have the street cred of Worcester, Vaillant, or Ideal. But, they’re rated extremely highly by engineers. 

The old and new boilers from Potteron are well built, and tend to last.

That was the generally consensus, until they started to trying to make cheaper boilers, which led to a reduction in warranty to just 2-years.

And, that doesn’t exactly fill a buyer with confidence.

Price Comparison

Potterton tend to sit just below Worcester, Vaillant and Baxi in terms of price; similar to the Ideal.

And, given all of the above boiler brands are bigger, and have a better service support network, those are the brands that engineers tend to install.

#5 – Baxi

Baxi’s quality rivals all the best boiler brands including: 

  • Worcester Bosch
  • Vaillant
  • Ideal

Like these brands, they offer a range of boilers including system, regular and combis.

Price Comparison

Price wise, expect them to be just slightly less than a Worcester Bosch equivalent.

#6 – Glow Worm

Glow-Worm tends to sit in the category of “best of the rest”, with other boiler brands such as Vokera, and Potterton. 

Glow-Worm are a cheap boiler brand. They tend to be used on budget renovations and rental properties.

Reliability wise, they’re certainly not known for being up there with the likes of Vaillant, Worcester, Ideal and Baxi.

That said, they do offer 2 and 5 year warranties on their boilers, so in the short-term, they’re cost effective.

Price Comparison

It’s not all bad-news. Glow-Worm boilers are regularly priced as “special offers” at local plumbing merchants.

So, that means they are cheap to buy, and cheap to install. Expect Glow-Worm to be priced similar to Vokera boilers, if not a little cheaper.

The Best Oil Boiler Brands

Not all boiler brands will produce oil boilers.

So, here are the best brands to keep note of, when shopping for an oil fuelled boiler.

#1 – Grant

#2 – Worcester Bosch

#3 – Vaillant

Which New Boiler Should You Choose?

The most important things to consider when choosing a boiler brand are:

  • Price
  • Reliability
  • Support
  • Warranty

All things considered, Worcester Bosch are the best value for money, when using an installer like BOXT.

If you need an oil boiler, you’ll need to use a local fitter. You can compare up to 3 quotes for Worcester oil boilers here.
