Installing a wood-burning stove in a cottage can totally transform your space (and heating bills), but it’s probably not something you do every day. If not a once-in-a-lifetime purchase, it’s certainly a once-in-a-blue-moon one, and regulations and compliance have likely changed since the last installation.
And, let’s face it, to 99% of the population the words regulation and compliance are downright boring – not what you want to be thinking about when shopping for an exciting addition to your cosy cottage.
However, considering the regulations and compliance is essential! They are there for everyone’s safety, and no one wants to risk installing something that could cause harm to themselves and their family. And, as beautiful as old Welsh cottages can be, the unique architectural features can create distinct installation challenges for installing a wood-burning stove. Careful planning is essential to navigate the structural and compliance challenges involved.
So there are definitely some things to think about, but it doesn’t need to be confusing or overwhelming. And with a little help, you can make sure that you think of everything you need to ensure a cosy, efficient and regulation-compliant setup.
In this guide, we break down the most critical factors to ensure a safe, efficient, and legally compliant installation that enhances the cosy cottage ambience. Whether you’re upgrading an existing stove space, or adding something completely new, we’ve got you covered.

Why Regulations Matter for Wood-Burning Stoves (and what you need to know)
Welsh cottages often feature older architecture with quirks such as narrow chimneys, limited ventilation, and draughty layouts. And while it adds charm and character to your building, it can also be the cause of more than a few challenges when it comes to any renovations or modernisations.
When adding a wood-burning stove to a cottage, regulations aren’t just red tape—they’re vital for safety, efficiency, and sustainability. Without careful consideration of these guidelines, you could face hazards like poor air quality, fire risks, or even fines.
But don’t worry, these risks can be easily avoided with a little careful upfront planning and consideration.
There are a couple of things you need to think about to get your installation right and make sure it’s safe for you and your family, including;
- Chimneys and Ventilation
- Eco-Design
- Fire-safety
- Stove placement
- Stove aesthetic
- Maintenance
Understanding these factors will help you navigate the challenges of installation while ensuring you remain compliant with modern standards, making sure you are safe.
1. Chimneys and Ventilation: What you need to know…
Chimneys and ventilation are essential for the safe and efficient operation of a wood-burning stove.
But even if you have an existing space, it doesn’t automatically signify suitability in a traditional cottage. You may need to consider upgrades and additions to make it safe for use in the modern day.
So, what do you need to think about when it comes to traditional cottages?
Wood-burning chimney requirements…
A chimney provides the draft needed to pull in air for combustion and expel smoke and harmful gases like carbon monoxide, and without a properly functioning chimney, safety and efficiency are compromised.
However, older chimneys may be too narrow, winding, or even unlined, leading to poor drafts or leakage of harmful gases – meaning they can’t be safely used.
So, what’s the solution?
Before you get started a thorough professional inspection is required to identify cracks, corroded joints, or other issues, this will usually comprise a visual inspection and a smoke test.
For older homes, it is often necessary to upgrade or modify the chimney to meet current standards.
And, while it might not be top of your priority list at installation, you will need to keep up with regular maintenance and sweeping of your chimney to keep it functioning in tip-top shape.
When to Install a Flue Liner
A flue lining is a protective layer inside a chimney that ensures smoke, gases, and particles are safely vented outside while preventing leaks and protecting the chimney structure from damage.
Most homes built before the 1960s will not have a flu liner, relying on brick alone which can deteriorate over time. Although a liner is not a building regulation it is a common and recommended solution if your old cottage chimney is not suitable for use with a modern wood-burning stove.
A flu liner will improve draft, enhance efficiency, and shield against corrosive byproducts, ensuring a safer and cleaner burn even in older homes.
Wood-burning stove ventilation requirements
Ventilation is, of course, equally important, as wood-burning stoves require a steady oxygen supply for efficient combustion. Proper ventilation ensures your stove operates safely while delivering maximum heat output.
You might already have adequate ventilation in your home for a wood-burning stove, but this will depend on your insulation and the stove you choose.
You will need additional ventilation if any of the following apply:
- You install a stove with a heat output of over 5kW
- You have an air-tight or well-ventilated cottage
If either of these apply, you will need to install additional vents, to support combustion and prevent smoke build-up.
A professional will be able to advise on the location of these vents depending on your stove’s specifications and the layout of your home.
2. EcoDesign Compliance and DEFRA-Approved Stoves
This one applies whether you are in a cottage, a newly built home or somewhere in between, as it’s a blanket regulation for all wood-burning stoves.
Since 2022 ,all stoves sold and installed in the UK must comply with the EcoDesign standards, which are strict emissions guidelines designed to protect air quality and health.
These guidelines cover a range of safety and emissions considerations and include:
- Emission Limits: strict limits on pollutants like PM, CO, and NOx
- Efficiency Standards: must achieve a minimum of 75% thermal efficiency (some up to 90%)
- Sustainability Features: Modern stoves are designed to burn fuel more efficiently, minimising both waste and emissions.
These regulations ensure that your wood-burning stove is safer and more environmentally friendly than the old-school alternatives.
DEFRA-Approved Stoves in Wales
In addition to the Eco-Design regulations, some areas in Wales fall within what’s known as Smoke Control Areas (SCAs). These are designated regions with restrictions on the emission of smoke from chimneys to improve air quality. In these areas, it’s prohibited to emit smoke from a chimney unless you’re burning authorised fuel or using an exempt appliance.
If you live in one of these areas you’ll need to install a DEFRA-approved stove, which is again, designed to reduce harmful emissions, making them environmentally friendly while maximising heat output.
It’s worth remembering that all DEFRA-approved stoves must also comply with EcoDesign regulations, but not all EcoDesign-compliant stoves are DEFRA-approved unless specified, so you’ll need to check if it’s a specification in your area.
To see if you live in a Smoke Control Area, check out the Wales Smoke Control Areas Map, an interactive map which lets you know if your area has any regulations around smoke control.
3. Fire-safety: what you need to think about with wood-burning stove
Hot take: stoves get extremely hot🔥 (see what we did there).
Although fires from stoves are extremely rare, you do need to take some precautions and follow manufacturer and building regulations to ensure that you are minimising the risk of fire from your stove.
So, there are a couple of things to think about…
What kind of hearth do you need for your wood-burning stove?
The hearth of your fire should be able to defend against any stray flames, which is why it needs to be built using non-combustible materials such as slate, granite, or tempered glass as these can withstand high temperatures without catching fire or degrading.
Plus there are some size rules around the size of your hearth…
For stoves with an operating temperature under 100°C, the hearth must extend:
- At least 300mm in front of the stove door.
- At least 150mm on either side of the stove.
For stoves that reach temperatures over 100°C, the hearth thickness and dimensions may need to be increased for safety. The exact specifications will depend on the stove’s heat output and the manufacturer’s guidelines.
In all cases, the hearth must comply with Building Regulations, which outline specific requirements for fire safety.
How much clearance do you need for your wood burner?
Again – as we’ve mentioned, stoves get hot – so they need to be placed a safe distance away from any nearby combustible materials (e.g., wooden walls, furniture, curtains, or other flammable items). The last thing you want is for an otherwise safe stove to cause damage (or a fire) to another part of your home.
The distance between the stove and combustible materials is what we refer to as clearance. This distance is necessary to prevent these materials from overheating, which could lead to a fire.
The specific clearance required is often determined by the stove’s design, heat output, and flue diameter and is outlined in the manufacturer’s installation instructions.
However, generally speaking, stoves must be placed at least three times the flue’s diameter away from nearby wood or other flammable materials. For non-combustible materials, you can reduce this distance while maintaining safety.
4. Stove placement: where to put your wood-burning stove
Yes, clearance is important – you don’t want to set anything but the wood inside the stove on fire. But you also have to think about how the heat will flow through the space, and where to put your stove to optimise this.
Many traditional cottages have uneven layouts, small rooms, thick walls, or quirky architectural features that can make heat distribution challenging, so addressing these factors is key to ensuring efficient heating.
If you don’t think about it you may find you have an under or overpowered stove that either burns inefficiently or struggles to heat up the whole room – a lose, lose if you will.
Where to position the stove for optimal warmth
Even with the right size of stove, you need to make sure it’s in the right place to optimise the heat.
Putting your stove in a central location is one of the best ways to maximise heat distribution as it allows heat to radiate throughout surrounding rooms and reduces cold spots.
How to improve heat distribution
If your cottage has an open-plan layout heat can flow more freely, so placing the stove in an area with open doorways can help the heat circulate better between rooms.
For small or enclosed spaces, additional measures can help heat flow throughout the whole house including:
- Stove Fans: heat-powered fans sit on top of the stove and help push warm air further without requiring electricity.
- Air Vents or Ducts: can allow heat from the stove to reach other parts of the house, particularly in multi-level homes.
By carefully considering the layout of your cottage and taking steps to improve insulation and airflow, you can ensure your wood-burning stove provides consistent, comfortable warmth throughout your home.
How to improve heat retention…
Older cottages often suffer from draughty windows, doors, or poorly insulated walls, which can allow valuable heat to escape. Enhancing your home’s insulation is a crucial step to making the most of your wood-burning stove’s output.
Ultimately extra insulation in the walls, roof and flooring with significantly increase your home’s ability to retain heat.
But improving insulation doesn’t always have to mean a huge renovation project, there are loads of things that you can do to improve insulation, such as draught excluders, heavy curtains, thermal blinds or weatherstripping around doors and windows to seal gaps.
5. Choosing a Stove that Suits Your Cottage’s Aesthetic
The right wood-burning stove is about more than functionality – it’s an opportunity to enhance and reflect your cottage character. Whether it’s rustic or has a more traditional feel – you’ll be able to find a stove that suits you.
These are some of the options:
1. Traditional cast-iron stoves
Cast-iron stoves are a classic choice for cottages with rustic or vintage interiors. Known and loved for their timeless design, intricate detailing and traditional shapes.
They pair beautifully with exposed stone walls, wooden beams, and heritage décor, adding warmth and charm that feels perfectly at home in older cottages.
Beyond their aesthetics, cast-iron stoves are excellent at retaining and radiating heat, keeping your space cosy even after the fire has burned out.

Contemporary Stove Options
If your cottage leans toward modern or minimalist design rather than traditional, then a sleek, contemporary stove can provide a stylish yet functional focal point. These stoves often feature clean lines, slim profiles, and larger glass viewing panels, offering an unobstructed view of the flames and a striking visual effect.
Contemporary stoves work well in open-plan layouts or cottages that blend traditional architecture with modern updates. One of our favourite modern models is the Dean Stoves “Sherford 8 Eco” (8+ kW), which has a sleek modern design, and is great for heating expansive spaces.
By selecting a stove that complements your cottage’s style, you’ll not only create a beautiful, cosy centrepiece but also ensure it enhances the overall character of your home.
Of course, which stove you choose is really up to you, the rules are there to be broken, and maybe you want to add a contemporary twist to a traditional home.
But whatever you want, it’s worth considering that different styles of stove will bring a different feel to your home – and you can mix and match in whatever way suits you.
6. Maintenance: Caring for Your Wood-Burning Stove
Regular cleaning is essential to keep your wood-burning stove operating efficiently and safely, especially in cottages where dust and ash can accumulate quickly.
Focus on cleaning key components, such as the glass door, firebox, and door seals, to ensure optimal performance. Removing ash build-up improves combustion and prevents damage to the stove’s internal parts, helping to extend its lifespan and maintain its visual appeal.
Do you need professional maintenance of your stove?
There is no legal requirement, but adopting a “prevention is better than cure” approach is recommended to avoid any issues with your stove or chimney, especially in old properties.
In addition to daily or weekly upkeep, scheduling professional chimney sweeping is also recommended once a year to prevent soot buildup and maintain optimal performance
And, for older chimneys in traditional cottages, yearly professional inspections are highly recommended to identify cracks, worn flue liners, or structural issues that could compromise safety or efficiency.
Staying on top of cleaning and maintenance helps ensure your stove remains a reliable and safe heat source in your home.
Have you thought of everything?
So there! Hopefully not totally overwhelming, and if you’re still reading I’m going to assume you’ve not fallen asleep.
