Common conservatory regrets and how to avoid them

36% of conservatory owners would build theirs differently if they got the chance again. Dodge potential disappointments before you start with our expert tips

Conservatories are quicker and cheaper than full-blown extensions and they tend to not need planning permission, so they’re a popular choice when it comes to extending. But is a conservatory right for you? And what do you need to know before you start? 

Embarking on any home extension project is as nerve-wracking as it is exciting. Perhaps the new space won’t look as good as you expected, or you won’t use it enough to justify the considerable upheaval and expense.

If you’re thinking of building a new conservatory, don’t let those concerns put you off. We’ve surveyed more than 100 conservatory owners* to find out why they had them installed and whether they had any regrets afterwards, so that you can make the right decisions from the start.

Should I buy a conservatory?

People add conservatories to their homes for all sorts of reasons. If you’d like a little extra space without the hassle of an extension you may be considering a conservatory instead, as they tend to be a quicker and cheaper option. We asked Which? members why they’d had their conservatories installed:

Whether you’re replacing an old conservatory or starting from scratch, it’s better to get your new room right first time and come away feeling content, not disappointed.

We asked conservatory owners if there’s anything they wish they’d done differently, so that you can learn from their mistakes.

What went wrong?

Some 36% of people we surveyed had some regrets when it came to their conservatory and would do something differently if they were starting again:

How to avoid conservatory regrets

1. Opt for self-cleaning or anti-glare conservatory glass

A third of the people who admitted they’d change something about their conservatory mentioned self-cleaning glass. It works using a special coating that reacts with sunlight to break down dirt, which is then washed away by the rain.

Benefits include saving time scrubbing hard-to-reach panes and keeping maintenance costs down. We’d only recommended self-cleaning glass if your roof will be steep enough, as it relies on rainwater carrying dirt away.

Head to our common pitfalls guide to find the right roof pitch and angles you’ll need.

In addition, 16% told us they would use anti-glare glass if they were doing their conservatory again. To find out more about the different types of glass and other ways to prevent glare, head to our guide to types of conservatory.

2. Think carefully about your conservatory size

Of the conservatory owners we spoke to who weren’t completely happy, 28% wished they’d chosen a bigger conservatory.

A bigger conservatory can cost more, take longer to build and might need planning permission, but the extra time and effort could pay off if you then use the room more once it’s finished.

If you’re wondering how big to go, start by measuring out the dimensions of your future conservatory in your existing living or dining room. It’s easier to visualise the new space compared to an existing room, and you’ll be able to see whether your furniture will fit.

Early on, think about where you’ll position doors, electrical power points and TV aerial sockets so you can get maximum use out of your new conservatory, as these things are hard to change down the line.

3. Splash out on a glass conservatory roof

A fifth (21%) of people regretted their polycarbonate roof and wished they’d chosen glass instead.

While they’re pricier, glass roofs are more thermally efficient than polycarbonate, and let in more light and less noise. If you can afford it, it’s probably worth the extra expense.

4. Pick a shape that connects with your home

Some 16% of people we asked said they wished their conservatory was a different shape. One person said an ‘L’ shape would give them access from the kitchen as well as the living room.

Before you begin, think through all the different ways you hope to use the new space and how it will connect with the rest of the property.

There’s a trend to build a conservatory that opens up the back of your home, creating an open-plan shape. For this type of build, you’ll need to think carefully about thermally efficient materials and planning good heating and ventilation.
