clearSkies are the objective & independent emissions and energy performance certification mark for solid fuel stoves and fireplaces. For a few years, the stoves in the Charlton & Jenrick range have been clearSkies certified. The clearSkies certification scheme is for wood-burning stoves and was launched in 2020.

Going further than Ecodesign Ready.

The clearSkies initiative, created from an original idea by the Stove Industry Alliance and industry partners, is a “one-stop” certification mark to promote the best performing wood-burning stoves on the market.

As mentioned, all Charlton & Jenrick wood burners are all certified with clearSkies – a testament to our continual commitment to cleaner, greener ways to keep warm. The scheme is independently owned and run by clearSkies Mark Ltd, administered by Kiwa Ltd and open to any UK appliance manufacturer to apply.

Improving air quality:

A clearSkies appliance will help to improve air quality by dramatically reducing emissions. Independent tests show that a clearSkies appliance produces up to 90% fewer emissions than an open fire and up to 80% less than a stove that is 10 or more years old.

clearSkies Levels:

As you can see from the diagram above, the clearSkies start from levels 2 to 5. All clearSkies Level 3 and above comply with both systems of emissions certification. Even better than this, it is now possible to identify products that are cleaner burning and outperform the basic Ecodesign requirements. Level 4 clearSkies indicates that a composite of emissions and efficiency is at least 15% better than baseline, and Level 5 is 15%+ better than level 4 – all have DEFRA exemption.

Charlton & Jenrick – Reaching the top levels of efficiency!

Most Charlton & Jenrick products achieve a clearSkies level 5, and the remainder are level 4, so you can be totally confident that our stoves are amongst the very best available wood burners on the market.

Things to consider:

By swapping from an open fire to a clearSkies-approved stove, you will reduce your particulate emissions by up to 90%.

It costs less to run a clearSkies stove than a 10-year-old stove, as you need fewer logs for the same heat output.

By investing in a clearSkies stove, you are future-proofing yourself. Not only does a clearSkies stove meet various legislation – it often exceeds it!

A clearSkies stove is a low carbon, sustainable way to heat your home

All clearSkies stoves & fireplaces have been independently verified as meeting the latest standards. For clearSkies Level 3 and above, this includes UK legislative requirements on smoke control zones
