Tefal SV7040 Liberty Steam Generator UK Review 

By  Carol

Thanks for taking your time to read our review of the Tefal SV7040 Liberty Steam Generator. This is the most powerful iron in the Liberty range, so it's the top model.

With 120g/min of continuous steam and a 350g/min steam shot, it is one of the highest spec irons that we have reviewd so far. It's quite a new model and there are not that many reviews available , so we can only really tell you how good it is from new, not a long term view.

That being said, it is a Tefal model, we expect very high reliability standards from a brand like this and of course it comes with a 2 year warranty.

Who Would Buy this Iron?

How Buyers Rate this Tefal SV7040 Model

Buyer Satisfaction
  • Overall this steam iron has an online buyer satisfaction rating of 76%
  • 70% of all online buyers gave this a full 5 star rating
  • We found one buyer who gave this product a poor rating and that's because they thought it was too noisy

The above ratings are based on over just a few online reviews from various iron and laundry websites, at the time when we did our research. I would say these ratings are quite low considering how good the iron is and when more are sold the overall rating will go up to around 90%

The low number of reviews shows that this iron is not selling in large amounts yet but it's pretty new and is a premium model, so it's not for everyone. It is a premium iron at a premium price.
