Best Which? rated boiler brand in the UK in 2020

We are delighted to have been recognised as a Which? Best Buy brand again in 2020.

As a business, we remain fully committed to supporting our installers and helping them maximise their businesses. The Which? Best Buy accreditation is an important one, as it is highly regarded and well trusted by consumers.

With our entire range of domestic boilers Which? Best Buy accredited again for another year running , together with our extended guarantees of up to ten years on some models, installers can recommend Vaillant boilers to their customers with absolute confidence.

Which? surveyed more than 200 of its trusted heating and plumbing engineers their thoughts on the boiler brands they worked with, looking at installation and services, fault fixing and the availability of parts and spares. We are proud to say that once again, Vaillant are engineer’s boiler of choice, being the only brand which received the 5-star seal of approval for build-quality.

The Which? Best Buy report stated: “Vaillant is the darling boiler brand of our expert engineers. It’s the only brand with their five-star seal of approval on build quality, and they’re quick to recommend it too.”

One engineer said: ‘Vaillant is one of the top brands on the market and that’s clear when you look inside these boilers. The configuration of parts is well thought out for the engineer when repairing or replacing parts. It’s a very reliable boiler brand with a very good guarantee.’

Our latest accolade is yet another way in which we are supporting our loyal installers by making it even easier to sell the Vaillant brand to their customers.

Proudly Supporting Installers - Advice and support hub

Although much of the country remains on lockdown due to the coronavirus (COVID-19) pandemic, many professionals in the plumbing and heating industry are still required to carry out front line work to ensure homes, hospitals and businesses across the UK have access to heating, hot water and other essential services. Engineers carrying out these duties need guidance from the relevant authorities to help them to look after themselves and their customers.

On the other hand, many self-employed tradespeople are concerned about the impact that the nationwide lockdown could have on their businesses, with projects being put on hold and non-essential work being cancelled.

These are unprecedented times, which is why our aim to proudly support installers is more important now than ever before.

Here, you will find the latest information from the government, NHS and industry bodies and what it means for you and your business, as well as resources from Vaillant to support your earnings, learning and wellbeing.
