As environmental concerns continue to shape the UK’s regulatory landscape, advancements in stove technology have been made to meet stringent eco-friendly standards. Multi-fuel stoves, widely popular for their versatility, efficiency, and aesthetic appeal, are not exempt from these regulations.
In this article, we will explore the latest regulations and rules governing multi-fuel stoves in 2023, with a focus on Ecodesign, planning permission, fuel liners, hearth requirements, and ventilation regulations in the UK.
What is Ecodesign?
Ecodesign is an initiative by the European Union to improve the energy efficiency and environmental performance of products, including stoves and fireplaces. It came into effect in the UK on January 1st 2022.
In the UK, Ecodesign regulations have been embraced as part of the government’s commitment to reducing carbon emissions and mitigating climate change and, as of 2023, all newly-manufactured stoves must meet the Ecodesign standards, ensuring lower emissions and higher efficiency compared to older models. Ecodesign sets out maximum emission levels of PM (Particulate Matter), CO (Carbon Monoxide), OGC (Organic Gaseous Compounds) and NOx (Nitrogen Oxide).
Ecodesign only affects those room-heating appliances made available for sale from 2022 onwards; stoves and fireplaces already installed will not be affected.
Will Ecodesign affect the heat produced in a multi-fuel stove?
No, the implementation of Ecodesign regulations does not necessarily impact the heat output of multi-fuel stoves. The primary aim of Ecodesign is to reduce harmful emissions, making these stoves more environmentally friendly. Manufacturers have adapted by employing innovative design features and technology to maintain or even improve heat output while complying with the Ecodesign standards.

Is planning permission required to install a multi-fuel stove?
In most cases, installing a multi-fuel stove in the UK does not require planning permission. Permitted Development Rights (PDR) allow homeowners to make certain improvements to their property without seeking planning permission. Under PDR, you can install a multi-fuel stove, provided it meets specific criteria, such as not being installed on a listed building or within a designated conservation area. However, it is always recommended to consult with your local planning authority or a professional installer to ensure compliance with local regulations.
Is it a legal requirement to have a flue liner?
While it’s not a legal requirement, using a fuel liner is highly recommended when installing a multi-fuel stove. A flue liner is a flue or chimney lining that ensures proper venting of combustion gases and helps prevent dangerous emissions, such as carbon monoxide, from entering your living space. A fuel liner will increase efficiency, help keep your chimney clean and improve safety.
Your wood burning stove needs to meet the building regulations listed in Document J, which recommends (but does not require) that flue liners are used.
Top Hearth Requirements
The hearth is the base on which the multi-fuel stove sits, and it must meet certain requirements to comply with UK regulations. The top hearth, also known as the stove hearth or constructional hearth, must be made from a non-combustible material, such as stone, concrete, or a suitable hearth pad such as enamel. It should extend a certain distance beyond the stove’s footprint to prevent accidental fires. The specific dimensions and constructional requirements may vary based on the stove’s heat output and other factors, so it is vital to follow the manufacturer’s guidelines and UK building regulations.
Ventilation Requirements
Proper ventilation is essential to ensure the safe operation of a multi-fuel stove. Adequate air supply allows for efficient combustion and reduces the risk of carbon monoxide build-up.
The ventilation requirements of your home will depend in part on when it was built; homes built after 2008 are designed to have an air permeability of 5m3/hm2 or less, due to the increased energy efficiency. Homes built before 2008 are unlikely to meet this level of air permeability. You can have your stove fitter test your home’s air permeability.
For homes with an air permeability of 5m3/hm2 or more, i.e. most older homes, ventilation is only required for stoves with heat outputs above 5kW, and this is done in increments of 550mm2. For example, a 6kW heat output would require 550mm2, a 7kW heat output requires 1100mm2, an 8kW heat output requires 1650mm2 and so on.
For homes with an air permeability of 5m3/hm2 or less, i.e. any home built since 2008, and some homes built before, the increments of 550mm2 start from 0, so a 1kW heat output would require 550mm2, a 2kW heat output requires 1100mm2, and a 3kW heat output requires 1650mm2.
This ventilation can be achieved through vents in the wall or an air brick. Installers must carefully calculate the required ventilation to meet building regulations.
