Firewood frequently asked questions
Where does your firewood come from?
All our firewood comes from sustainable woodland and forestry as part of a replanting scheme. It is sourced responsibly through our excellent relationships with the Forestry Commission, local small forestry companies, and Sussex and Surrey coppice groups. We guarantee that our firewood is top-quality hardwood that is well-seasoned for clean, efficient burning in open fires, wood burners, and multi-fuel stoves.
What types of firewood do you sell?
All our firewood is finest-quality hardwood, well-seasoned and sourced from sustainable forestry and woodland. You can read about our firewood in-depth on our dedicated page.
How long can I store my wood for? Is it likely to rot?
Firewood does not have a use-by date, but some hardwoods like silver birch, alder, maple and poplar are more prone to rotting down. Store your logs in a dry, covered place and they won’t rot and will remain free of moisture and fungus. If you stack your logs along a wall, be sure to leave a gap between the wood and the wall so that air can circulate.
How should I store my firewood indoors?
When storing firewood indoors, it’s crucial to adhere to safety precautions to minimise the risk of fire hazards. Ideally, keep your entire firewood stock separate from the room housing your wood burner, storing it outside or in a garage. However, if needed for convenience, a small amount of properly dried firewood can be stored indoors. Ensure that firewood is kept away from heat sources and follow the manufacturer’s instructions regarding minimum distances from combustibles.
To minimise fire risks, only bring indoors the quantity of firewood that will be used within the next two days. Never store firewood on a wood burner or multi-fuel stove, as this can lead to ignition. Additionally, if your wood-burning appliance features an integrated log store, carefully follow the manufacturer’s guidelines on appropriate distances and load capacities to maintain safety and minimise risks.
How should I store my firewood outdoors?
When storing firewood outdoors, it’s essential to prevent moisture build-up and decay. Utilise a slatted log store with a roof to shield the wood from excessive rain, ensuring minimal moisture absorption. Arrange wood from newest at the bottom to oldest at the top to facilitate drying, especially for self-sourced wood. Elevate logs for ventilation, avoiding tight stacking to allow airflow and help the drying process.
Choose a location away from potential water sources and opt for areas with ample sunlight and minimal exposure to high winds.
How do I start my fire?
Start by screwing up some newspaper, twisting it round three or four times, then place a small amount of kindling wood on top of the paper in a rough pyramid shape. Light the paper, wait for it to catch, then place a little more kindling on, taking care not to snuff the fire out. Once the fire is going, place your larger logs on top.
How much smoke will it produce, and will it spit and spark?
There will always be smoke when you first light your fire, but then the flames catch hold and the heat starts to rise, forming a base fire. Once this base fire is burning steadily, you can add small logs to bring the heat up. How much the fire smokes and sparks will depend on the type of wood you’re using. Most good firewood merchants will supply hardwood logs only, which means there will be minimal spitting and sparking. Hardwood logs will occasionally spit and send sparks flying out if there are small insects under the bark. Softwood logs like pine and hazel produce more sparks because there is more moisture and resin in the wood – which is something to be aware of when you’re sourcing your own firewood.
How long do Four Seasons Fuel logs burn for?
This is a difficult question to answer as there are so many variables, such as:
- The size of your fireplace
- Weather conditions
- The type of firewood
- Whether you’re mixing your firewood with coal or smokeless briquette fuels
However, as a rough guide, you should get 4-5 hours of burning time with generous heat and a steady flame from our seasoned hardwood logs.
What's the difference between seasoned and unseasoned wood?
Seasoned wood refers to wood that has been dried to reduce its moisture content, typically achieved by leaving it in the right conditions for a period of at least a few months. Seasoned wood is preferred for burning as firewood because it has a lower moisture content, making it easier to light, producing more heat, and burning cleaner.
Unseasoned wood, also known as green wood, is wood that has not undergone the seasoning process to reduce its moisture content significantly. All the wood we supply is either well-seasoned or kiln-dried.
How many logs in a bulk bag?
Like most firewood suppliers, we sell logs by volume rather than weight, and the approximate size of a bulk bag is 85cm x 85cm x 85cm. We cut our logs to approximately 22.8cm (9 inches).
Why buy firewood in bulk bags?
Buying firewood in bulk bags offers several advantages:
- It’s more cost-effective: Purchasing firewood in bulk bags is often more cost-effective than buying smaller quantities.
- It’s convenient: Bulk bags contain a larger quantity of firewood, reducing the frequency of purchases and the need for multiple trips. This is especially convenient for those who rely on firewood for heating or cooking regularly.
- It’s easier to store: Bulk bags provide a convenient storage solution for firewood. They can be stacked neatly in a garage, shed, or outdoor storage area, taking up less space compared to loose firewood. This helps keep the area organised and minimises clutter.
- It is better for the environment: Buying firewood in bulk can be more environmentally friendly compared to frequent small purchases, as it reduces packaging waste and transportation emissions associated with multiple trips.
Overall, purchasing firewood in bulk bags can offer cost savings, convenience, and peace of mind regarding quality, storage, and environmental impact.
How do you deliver my firewood?
We deliver your firewood using a truck with a tail lift and place it in your garage or driveway. Please note it’s not advisable to unload a pallet onto a loose surface like a gravel driveway, but we’ll get your firewood as close to your chosen storage area as possible.
Charcoal frequently asked questions
Why is Four Seasons Fuel charcoal so good?
We’ve been supplying the finest quality barbecue charcoal for 30 years. Packed onsite at our farm in West Sussex, our charcoal boasts exceptional performance, igniting quickly and reaching optimal cooking temperatures in just 15 minutes. Unlike competitors, our charcoal doesn’t impart any undesirable flavours to your food, as it has no need for lighter fuel or petroleum-based fire-starters.
How long does it take for charcoal to reach the right cooking temperature?
Once your charcoal is successfully lit, it will take approximately 15-20 minutes to reach the right temperature.
How long will charcoal burn for?
Our charcoal will give you two to three hours of cooking time on a standard grill barbecue. If you’re using them in a smoker these times will be extended.
How do you know when to start cooking on charcoal?
Timing is crucial when using charcoal, and a fundamental aspect is gauging its temperature. A reliable guideline is to begin cooking once the charcoal has achieved a glowing white-hot appearance with a red centre. Charcoal that remains black or grey with flames indicates it isn’t yet hot enough for cooking.
How do I add a smoky flavour to my food when cooking with charcoal?
The best way to infuse your food with smoky flavours and delicious aromas is by using top-quality charcoal. You can also enhance the flavour using BBQ smoking woodchips – for example, we offer whiskey oak chunks that add an authentic smoky taste to your food.
Coal frequently asked questions
Can you still burn coal at home in the UK?
Yes, you can, but on 1 May 2023 it became illegal to use bituminous coal (also known as house coal). Instead, alternative house fuels such as manufactured solid fuel (MSF), which can be derived from various materials including coal, wood, plant-derived materials, waxes, or petroleum products, must be used for combustion in domestic premises in England. As a result of the legislation, Defra (Department for Environment, Food and Rural Affairs) implemented the ‘Ready to Burn’ scheme for manufactured solid fuels (MSFs) and wood fuel. All the coal we sell is HETAS-approved and meets all UK legislation.
What does it mean to be an Accredited Coal Merchant?
In 2015, we became an Accredited Coal Merchant, which means we adhere to the Coal Trade Code and are committed to the following principles:

Can I get coal delivered?
Yes, depending on where you live, we can offer free delivery on orders over £50 or for certain postcodes there is a small delivery charge. You can also ‘click and collect’ from our yard near Billingshurst if easier.
Can smokeless coal be stored outside?
Yes, all smokeless coal can be stored outside. However, it’s advisable to have a coal bunker or suitable cover to maintain good airflow and keep the coal off the ground. A great alternative and simple solution to a coal bunker is reusing an old dustbin or wheelie bin.
Is smokeless coal suitable to use in a multi-fuel stove?
Yes, smokeless coal is suitable for use in a multi-fuel stove for several reasons. It produces a high heat output, burns cleanly with minimal ash residue, and doesn’t leave behind soot or tar that can damage your stove and flue. Compared to normal coal, smokeless coal offers a cleaner burn with fewer maintenance issues.
Additionally, smokeless fuels generally last longer than traditional coal and are more cost-effective over time. They can increase heating efficiency, with some smokeless fuels generating up to 65% efficiency in a multi-fuel stove compared to the 37% efficiency of traditional house coal in an open fire. This means more heat is retained in the room rather than lost up the chimney.
Gas frequently asked questions
Do you sell gas for industry?
Yes, we supply gas for a variety of industrial and commercial uses, including hospitality, welding, roofing, commercial heating and farming practices.
What is patio gas?
Patio gas is an all-weather propane gas that is ideal for patio heaters and cooking or catering on BBQs and grills. It is for outdoor use only and must not be used indoors.
What is beer/beverage gas?
Beverage gas or beer gas is a gas specifically used by pubs, bars, cafes, restaurants and clubs to help provide the fizz to your drink. Beverage gas comes in different mixes depending on the drink. We stock pure CO2, 60/40 (60% CO2, 40% nitrogen) and 30/70 (30% CO2, 70% nitrogen). Sizes range from 6.35kg CO2, 10L 60/40 and 50L 30/70, right up to 34kg CO2, 50L 60/40 and 50L 30/70. Please call us for more details.
What is butane gas?
Butane is a hydrocarbon gas and is commonly used as a fuel propellant and refrigerant. It is always stored in blue cylinders and is ideal for caravans and camping, single burner cooking appliances, outdoor cooking and domestic and commercial mobile heating.
What is propane gas?
Propane gas is another hydrocarbon gas, similar to butane and commonly used as a fuel for domestic heating, cooking, and hot water systems, as well as for commercial and industrial applications such as forklifts, generators, and agricultural equipment. Propane is often stored and transported in pressurised cylinders or tanks, typically coloured red in many regions for easy identification. It’s important to handle propane cylinders safely and store them outdoors in well-ventilated areas due to its flammable nature.
What’s the difference between propane and butane?
Propane and butane are both forms of LPG gas but serve distinct purposes. Propane, with its lower boiling point of -42°C, is favoured for outdoor use like heating, BBQs, and commercial appliances. In contrast, butane, with a higher boiling point of -2°C, is ideal for indoor applications such as portable heaters and single-burner cooking appliances, and it boasts higher energy output per cubic meter. Propane finds its niche in commercial settings, operating tools, ovens, forklift trucks, and providing heat and cooking fuel for caravans or patio heaters. While both can be used on BBQs, propane remains the popular choice, especially for colder temperatures.
What regulator fits my bottle?
- A screw-in regulator such as a low-pressure 37mbar regulator, a low-pressure 37mbar hand-wheel regulator and a high-pressure regulator will fit the following bottles: 47kg, 19kg, 11kg (red), 6kg, and 3.9kg
- Propane bottles
- Most new BBQs or patio heaters come with a 27mm regulator. A 27mm clip-on regulator will fit the following bottles: 11kg (green) and 9kg
- A 21mm regulator will fit the following bottles: 13kg and 7kg
- Butane bottles

What can I use the 47kg propane gas cylinder for?
Ideal for both domestic and commercial properties, our 47kg propane gas cylinder can be used for home heating and cooking, industrial heaters, generators, static caravans and agricultural heating.
How many litres are in a 47kg cylinder?
91.8 litres
How do ‘clip-on’ and ‘screw-in’ regulators work?
Clip-on and screw-in regulators are devices used to regulate the flow of gas from a gas bottle, such as propane or butane, to appliances like barbecues or stoves. The main distinction between them lies in their attachment method: clip-on regulators are pushed onto the bottle’s top with a spring-loaded clip mechanism, while screw-in regulators are threaded directly into the bottle’s top for a secure fit.
Despite this difference, both types function similarly by reducing the high pressure of the gas in the bottle to a safe level for appliance use. When choosing between them, compatibility with the gas bottle and appliance requirements should be considered, along with adherence to safety standards and regulations.
Why do you need a regulator on a gas bottle?
Regulators are crucial when using gas bottles as they control the pressure of the gas, ensuring it’s suitable for safe appliance use. They help prevent hazards like leaks, fires, or explosions by maintaining safe pressure levels. Additionally, regulators ensure consistent gas flow to appliances, promoting efficient and reliable operation. They’re designed to match specific gas bottles and their contents, ensuring compatibility, and preventing damage. For example, a green patio gas bottle pairs with a clip-on regulator, while a red propane bottle requires a screw-in regulator.
With features like pressure gauges and flow rate adjustments, regulators also make it easier for users to monitor and control the gas supply, adding convenience and safety to the system.
Can I have a refund on my cylinder if I have lost my refill agreement/receipt?
Unfortunately, without proof of purchase we cannot issue any refunds.
Is my cylinder 100% full?
All bottles are filled to 90% capacity; the remaining 10% is left free for expansion of liquid.
I've just bought a new BBQ, what gas bottle do I need?
Most new BBQs come with a 27mm regulator fitted and will need an 11kg or 9kg green patio bottle.
I've just bought a new mobile heater, what gas bottle do I need?
Mobile heaters come fitted with a 21mm regulator and will need a 13kg or 7kg butane bottle.
How should I store gas bottles?
We often get asked this question, as knowing how to handle and store your gas bottle safely should always be a priority. Here are our guidelines on how to safely store your gas bottles wherever you are…
What to do:
- Gas bottles should be stored and used in a stable, upright position
- Always store gas bottles outside, in a well-ventilated area away from building entry/exit points and drains
- Ensure gas bottles are stored away from any heat or ignition sources
- Always replace safety caps/plugs when the gas cylinder is empty or not in use
- Always pay attention to any safety and operating notices displayed in the vicinity
What not to do:
- Store or use gas bottles below ground level
- Don’t use or store gas bottles lying down, they could leak which can be very serious
- Don’t use gas bottles in places where gas is prohibited, such as high-rise flats
- Don’t keep gas bottles near corrosive, toxic or oxidant materials
- Don’t use propane cylinders indoors – they have a higher pressure than butane cylinders so they are only safe to use outside
- Don’t drop gas cylinders off vehicles or platforms, as this could damage their valves or the cylinders themselves
Heating oil frequently asked questions
What types of oil can I buy?
We sell kerosene and paraffin heating oil, both in bulk supply and for domestic use. Our paraffin can be used in lamps and heaters, including greenhouse heaters. It may produce a very faint odour, so if you require odourless heating oil, please contact us for a price for odourless kerosene.
Please note there are restrictions on transporting heating oils like paraffin, so if you need any help or advice, get in touch with us before you buy.
What is the difference between kerosene and paraffin?
Kerosene and paraffin are often considered similar, but subtle differences exist between them. Depending on their intended use, they may have additives incorporated. Kerosene typically has a strong odour, while paraffin contains additives to minimise odours. Additionally, kerosene may contain additives for specific applications like home barbecues or pharmaceutical use.
In essence, kerosene is a specific type of paraffin, with paraffin describing a broader group of hydrocarbons. Paraffin liquid fuel is usually more refined and distilled, producing less soot when burned. This is advantageous for those using paraffin in stoves and lamps to light their homes, as soot build-up can pose health risks. However, if your property lacks access to gas mains, kerosene is a more suitable option for home heating systems.
When is the best time to buy heating oil?
The best time to purchase heating oil is during the summer months. Despite the warm weather, this period sees lower demand for heating oil, leading to reduced prices. Buying during this time ensures that your tank is replenished well before temperatures drop, minimising the risk of running out of fuel and experiencing a cold house while awaiting delivery.
Soil, compost & biochar frequently asked questions
What is biochar?
Biochar is a by-product of charcoal production and is a soil additive that acts like a sponge, soaking up toxic gases, neutralising soil acidity and improving the absorption and retention of water and nutrients to boost the health of your plants.
How is biochar made?
We produce our own biochar on site using a process called pyrolysis, in which waste wood is heated in a low or zero-oxygen environment, burning off moisture to leave behind a porous charcoal-like material that leaves microscopic pores giving a home to a diversity of microbes and bacteria.
What is biochar used for?
Biochar application to soil brings numerous agricultural and horticultural advantages, including enhanced plant and soil health, acidity reduction, nitrogen leaching regulation, improved microbial properties, and boosted plant growth. Additionally, biochar proves beneficial in composting by curbing greenhouse gas emissions, retaining nutrients in compost material, and stimulating microbial activity, thereby expediting the composting process. Moreover, it aids in reducing ammonia losses, bulk density, and odour in compost.
