Vokera boilers score

Customer reviews of Vokera were mixed. While Vokera boiler owners were quite satisfied, one in 10 wouldn't recommend the brand to someone else. No other brand had as many customers say they outright wouldn't recommend their boiler's manufacturer to someone else.

This is in spite of 86% of Vokera owners being currently satisfied (4% feel neutrally).

 While Vokera boiler owner satisfaction isn't much lower than average, its proportion of detractors is unusually high. 

Vokera engineers' review

We heard from 198 expert engineers who scored brands on several tests. We asked them to score gas boiler brands on the following:

• The ease of sourcing spare parts 
• How easy it so to change a common component (a heat exchanger)
• The ease of servicing the boilers
• The build quality of the boilers
• The quality of technical support provided by the manufacturer
• Whether or not engineers would recommend the brand to consumers (we filter out incentivised and brand-affiliated engineers).

We aggregate all these scores and use them to create our 'overall engineers' score' which is 40% of our total brand score.

Vokera boiler reliability

Boilers are major purchases you should only make once every 10 - 20 years. You can keep yours longer if you get it regularly serviced and get faults fixed quickly.

We asked people who bought a boiler in the past six years whether theirs is fault-free. When faults are reported, we measure how serious it was, how long it took for the first fault to happen and that it was fixed by an engineer.

Using this data, Which? members can see which brands produce boilers less prone to fault than others.

Where to buy Vokera boilers

It's easy to rush into making a decision, especially if your boiler breaks down in winter, but we recommend getting a couple of quotes from a qualified heating engineer and comparing costs. Our Trusted Trader service can link you up with vetted boiler installers in your area.  

You could also buy a boiler yourself and hire an installer, though make sure you seek expert advice before doing so, to have your current heating system assessed and identify the type of boiler that meets your specific needs. If you buy a boiler without having an installer lined up, you could find yourself struggling to find someone willing to set it up for you. An installer may have access to trade or wholesale prices, and will be able to recommend a model based on a holistic assessment of your home and heating system.

Only a Gas Safe Registered engineer/installer can install a new boiler: it's both dangerous and illegal to do so yourself if you're not qualified.
