Independent double glaziers
By Liz Ransome-Croker
Article 3 of 5
We've asked more than 2,000 double glazing customers about their experiences with buying and having double glazing installed by big-name companies and independents.
83% of the 2,152 we spoke to turned to independents to buy and install their double glazing, instead of the large household names Anglian, Everest and Safestyle. But how does their service differ?
Our top-scoring double glazier got an impressive customer score of 84%, while the bottom just 54%. That's 30 points less.
As well as asking people how satisfied they are with a company and whether the would recommend it, which is what combines to make up our customer score, we asked people rate different aspects from 'very poor' to 'excellent'.
It included important aspects of the double glazing buying and installation process, such as knowledge of the salesperson, quality of products and installers communication.
Independent double glaziers ratings
What do we mean by independents?
Independents as a group primarily includes:
- local independent double glazing companies;
- independents not in someone's local area, but not a nationally-recognised brand.
It may also include local builders and joiners, who people are more likely to have used if you're having a home renovation, such as a new extension.
83% of the people we spoke to chose to use an independent. The main reasons were because:
- They are local to me, so I could easily arrange to visit them (58%)
- They weren’t pushy or intimidating/ didn’t pressure me (55%)
- They had a good reputation (49%)
- I like using independent companies as opposed to national companies (48%)
- I had used them before/ knew them (36%)
Rating the independents in this way is not to say that no one has had a bad experience. It's a varied group with a number of different types of companies, traders and situations.
But this at least gives you an idea of the average experience people had, and how that compares to the service offered by the household names.
