Choosing a conservatory company

Find out what conservatory owners really think of local builders and conservatory companies compared to national firms, such as Anglian Windows and Everest

One of the biggest decisions you'll face is whether to get your conservatory from a big national brand or a local firm or builder. Our research helps you make the decision based on conservatory owners' experiences. 

We've spoken to hundreds of conservatory owners to see what their experiences were with local and national firms, and whether they would recommend them to a friend.

National vs local conservatory firms

There are a few options when you're choosing a conservatory firm.

  • Buy off-the-shelf and install your conservatory yourself
  • Buy a package from a local conservatory installer
  • Buy your conservatory from one local company and get it installed by another
  • Go to a major national brand such as Anglian Windows, Everest, Sehbac or Ultraframe for the whole package.

Some people like the bigger brands because of their consistency and experience. Others prefer local firms for their more individual service. 

If you go local, you’ll also have to decide whether to pick an independent conservatory firm or a local builder, who is likely to have a wider range of skills than simply building conservatories. This may be good if your build is more complex or larger than average. 

When we asked Which? members (2015*) about their conservatory, one in 10 people said they bought it from a national brand – mainly from Anglian.

The majority of people (70%) bought their conservatory locally, with most opting for a local specialist conservatory company rather than a builder.

The table below shows how satisfied people were with their choice of different types of firms and how likely they would be to recommend them to family or friends. 

We also asked about the average cost of a conservatory and found that it varied by as much as £5,000 depending on what type of company people went with.
