Scope
What this checklist covers
The preparation ground these prompts walk through.
- How often the outdoor space is genuinely used once the evenings turn cold
- Whether the wish for heat is really a wish for shelter from wind
- What sits above, beneath and beside any position being considered
- Smoke, smell, embers and the effect on the household and neighbours
- Fuel, supply and storage questions for qualified installers
- Cleaning, covering, servicing and out-of-season storage
Audience
Who this checklist is for
- Owners who want an outdoor space to stay usable as the evenings cool
- Households weighing an open fire, an appliance or simply more shelter
- People planning a covered or partly enclosed outdoor area
- Anyone preparing questions before speaking to a qualified installer
Timing
When to use it
- Recording when and how the space would be used in colder conditions
- Listing what sits above and beneath any position being considered
- Preparing fuel, supply and clearance questions for qualified installers
- Noting how smoke and smell would affect the household and the neighbours
- Deciding what upkeep the household is genuinely willing to take on
Limits
When it is not sufficient
This is general planning preparation. These situations need a qualified professional, and often the relevant authority.
- Choosing a fuel, an appliance or the way it would be supplied
- Deciding clearances, positions or what may be used beneath any cover
- Any gas, solid-fuel or outdoor electrical work, all of which is professional
- Deciding what may be burned outdoors in your area
- Judging whether a surface or a structure tolerates heat, sparks or embers
The checklist
Work through the sections
Tick the boxes on paper or on screen — nothing is stored, so print the page if you want to keep your marks.
1.How often the space is really used when it is cold
Outdoor heat is bought on the strength of an imagined evening. The honest usage pattern is what should shape the conversation instead.
Write down honestly how often anyone sits outside once the evenings turn, and whether that is an established habit or a hope.
An appliance bought for a habit that does not exist ends up stored, covered and in the way, which is worth avoiding before choosing anything.
Note which part of the year you would want heat for, and whether that means taking the edge off summer evenings or genuinely cold conditions.
Those are different requests that lead to different appliances and different supply questions, and conflating them wastes everybody's time.
Record whether the wish for heat is actually a wish for shelter, since a draught removes more warmth than most heat sources add.
Owners often solve a wind problem with a heater and remain cold, when a screen or planting would have done more for the same effort.
Consider whether people gather standing or seated here, since warmth that works around a seated group often misses a standing one entirely.
How a group arranges itself decides where warmth has to reach, and it is something only the household can describe accurately.
Note whether the heat is wanted for atmosphere, for warmth or for cooking, because one appliance rarely does all three well.
Naming the main purpose narrows the field immediately and stops a compromise being chosen that satisfies none of the three.
Write down whether children, pets or older relatives would be around the heat, and pass that to whoever advises you.
Where children, pets or anyone unsteady will be near a heat source, ask a qualified professional what that means for the arrangement.
2.Whether you are heating people, the air or the surface
Heat outdoors behaves nothing like heat indoors. Being clear about what is meant to feel warm changes which questions are worth asking.
Consider whether the area is open on all sides, since heat in open air disperses and tends to be felt only close to its source.
This single observation explains most disappointment with outdoor heating and is easy to make before anything is chosen.
Note whether a wall, hedge or screen already holds warmth or breaks the wind at the position you have in mind.
A wall that warms through the afternoon does real work into the evening, and siting seating near it asks nothing in return.
Record whether you would rather have one gathering point people move towards, or warmth spread thinly across the whole area.
A gathering point changes how the space is used socially, while spread warmth changes what has to be supplied and where.
Write down whether the heat has to be movable, since anything that stays in one place fixes the layout around it permanently.
A fixed source commits the furniture arrangement, the circulation and often the shade plan, all of which is worth deciding openly.
Ask what each type of heat source would actually feel like in an open space here, and record the answers rather than assuming.
Installers can describe the difference between radiant warmth and a fire in an open garden far better than a brochure can.
Consider whether warmth built into a surface is of interest, and treat it as a question about supply and build-up rather than a preference.
Any heat built into a surface involves electrical or plumbing work and must be designed and carried out by suitably qualified people.
3.Fuel, supply and the work that belongs with qualified people
Every fuel brings its own handling, its own supply and its own professional. This section is for collecting questions rather than reaching answers.
Note which fuels you would be willing to live with, and be honest about who would fetch, light and clear up after each of them.
The fuel that suits a household is usually the one somebody is prepared to handle on a cold evening rather than the one that sounds most appealing.
Ask what supply each option would need here, and treat every answer as work for a qualified installer rather than a decision to take now.
Every gas, solid-fuel and outdoor electrical arrangement is work for a suitably qualified installer, not something to settle in a brief.
Record whether any outdoor supply already exists and gather whatever paperwork you hold about who carried that work out and when.
Existing outdoor electrical work should be assessed by a suitably qualified electrician before anything further is added to it.
Write down whether an extension lead currently reaches this area, and raise that with an electrician rather than treating it as an arrangement.
A temporary lead crossing a garden tends to become permanent by habit, which is exactly the sort of thing worth flagging early.
Consider where a cylinder or a fuel store would sit if a fuel option were chosen, and confirm what applies with the supplier and the local authority.
Storage and handling of gas cylinders and solid fuel carry specific requirements to confirm with the supplier and the local authority.
Note whether reaching the heat position would mean a cable or hose crossing a route people walk, and record that as a question.
Anything crossing a walking route becomes a permanent nuisance, and it is far better raised while the position is still movable.
4.What sits above the heat source
The most important observation about a heat position is often made by standing on the spot and looking directly upwards.
Stand where a heat source would go, look straight up, and note everything above it: branches, a parasol, a canopy, a washing line or a window.
What is overhead is invisible on a plan and decisive in practice, and it takes a moment to record with a photograph.
Write down whether the area has any overhead cover, and treat what may or may not be used beneath it as an open question.
What may be used beneath a canopy, a parasol or any covered area is for the manufacturer and a qualified professional to confirm.
Consider whether a fixed heat source would rule out a parasol or a shade sail in the same position later in the year.
Shade and heat compete for the same spot, and committing to one without thinking about the other is a common regret.
Note whether the area sits beneath a balcony, a projecting floor or a room above, and flag that before anything else is discussed.
Any heat source beneath a balcony or below habitable rooms is a matter for qualified professionals and the local authority.
Record which windows, doors and vents are close by, and whether opening one would draw smoke or fumes indoors.
Where smoke or fumes could reach an opening, a vent or an enclosed space, ask a qualified professional before anything is planned.
Ask what clearances the manufacturer and the installer require around each option in this position, and record what they tell you.
Clearance requirements often rule out the most attractive position, and knowing them early saves reworking a layout around an appliance.
5.Smoke, smell, sparks and the people next door
Anything that burns affects more than the garden it stands in, and the effect lands on other people at unpredictable times.
Note which way the wind usually crosses the area, and where smoke would drift on a still evening as well as a breezy one.
Still evenings are when a fire is most appealing and when smoke hangs at head height rather than lifting away.
Record which neighbouring windows, gardens and washing lines sit downwind of the position you have in mind.
Neighbour relations are part of whether a fire feature gets used, and this is easy to work out before anything is bought.
Consider whether anyone nearby is affected by smoke, and whether that would change how often the heat is actually used.
An appliance used less often than expected because of who lives next door is worth knowing about before it is chosen.
Ask what local rules apply to burning anything outdoors here, and confirm the position with the local authority rather than assuming.
What may be burned outdoors, and when, is controlled in many areas, so confirm the position with the local authority before planning.
Write down what sits where sparks or embers would land, whether that is planting, decking, a hedge, a fence or a store.
Where embers could reach timber, planting or a boundary, ask a qualified professional what that means for the arrangement.
Note whether the smell of smoke on clothes, hair and cushions would bother anyone in the household.
Smoke smell lingers on soft furnishings long after the evening ends, and some households mind it far more than they expect to.
6.The surface beneath and everything standing beside it
A heat source has to stand on something and sit among other things. Both are owner-observable and both change what an installer will advise.
Note what the heat source would stand on, whether that is paving, decking, gravel, grass or a timber-framed terrace.
The surface underneath is often chosen long before the heat source and is rarely revisited when one is added.
Ask what the surface manufacturer says about heat, sparks and hot embers, and record their answer before any position is settled.
How a surface tolerates heat is for the manufacturer to state, and a surface that looks robust can still be marked permanently.
Consider what stands close by: furniture, cushions, planting, a fence, a store, a bin or cooking equipment.
The things around a heat source move about during a gathering, and listing them is what makes the position discussion concrete.
Write down where people would walk past the heat while carrying food and drinks, and whether that route could run elsewhere.
A route squeezed between a heat source and a table is created by furniture layout, and it can usually be designed out.
Record whether the position would block the main route in or out of the space once everyone has gathered around it.
People cluster towards warmth, so a source placed near the door quietly closes off the way back into the house.
Note whether the ground is level where the heat source would stand, and whether anything would rock or settle on it over time.
Loose or uneven ground under something heavy and hot is worth mentioning to an installer rather than correcting with a wedge.
7.Cleaning, covering and what happens out of season
Outdoor heat brings a routine with it. Deciding who carries that out is as much part of the choice as the appliance itself.
Write down who would clear ash, clean glass or wipe a heat source down, and whether that would honestly happen after every use.
An appliance that needs attention after every use is used less, and the household knows perfectly well whether that attention will be given.
Consider where ash and spent fuel would go, noting that it stays hot long after a fire looks out.
Ask the manufacturer how ash and spent fuel should be handled and disposed of, since it can remain hot well after use.
Note whether the heat source would stay out through the colder part of the year and, if so, how it would be covered.
Something left standing outdoors needs a cover that suits it, and something put away needs space that is genuinely free.
Ask what checking or servicing each option needs and who is qualified to carry it out, and record that before choosing.
Servicing of gas and solid-fuel appliances must be carried out by a suitably qualified person at the interval the manufacturer states.
Record where the appliance or its fuel would be kept when not in use, and check that the space is not already full of something else.
Storage for heat sources is usually assumed rather than allocated, and it competes with furniture for the same store.
Consider whether the option you are drawn to will still have parts available later, and ask the supplier about that directly.
One failed component often retires an outdoor appliance entirely, so availability of parts is a fair question at the outset.
Preparation
Documents and information to gather
Having these to hand usually makes the first conversation shorter and more useful.
- A sketch of the outdoor area marked with the position you have in mind and what stands nearby
- Photographs taken looking straight up from that position
- Any paperwork you hold about existing outdoor electrical work or supplies
- Manufacturer information for every heat source you are considering
- Notes on which way smoke would drift and whose windows sit downwind
- Whatever your insurer has told you about heat sources used outdoors
Records
Decisions to record before work begins
Write these down in your own words, with the date, so everyone is working from the same version.
- Whether heat is wanted for atmosphere, for warmth or for cooking
- Which part of the year the space is genuinely meant to be usable in
- Whether the heat source stays fixed in one place or can be moved
- Who lights it, clears it and cleans it after use
- Whether more shelter from wind is being considered alongside heat
- Which questions have been left with a qualified installer to answer
Professional review
Questions to discuss with qualified professionals
Bring these to the relevant qualified professional, supplier or authority. Requirements vary by project and location.
- What would each of these options actually feel like in an open space like this?
- What clearances do the manufacturer and installer require around this position?
- What supply would this need, and who is qualified to carry that work out?
- Who should I be asking about what may be burned outdoors in an area like this?
- What would this surface do if embers or heat reached it?
- How should this be stored, covered and serviced, and by whom?
- What changes if there is a canopy above this position, or a room above it?
- What do people most often regret about outdoor heat once they have lived with it?
Blind spots
Commonly overlooked items
- The wind that removes more warmth than any heat source adds
- A parasol ruled out by the heat source placed in the same spot
- Smoke drifting across a neighbour's washing line on a still evening
- Ash that stays hot long after the fire appears to be out
- Cushions and clothing that hold the smell of smoke long afterwards
- An extension lead across the garden treated as a permanent arrangement
- A heat source that ends up blocking the way back into the house
What this checklist does not do
- Nothing here selects a fuel, an appliance or a position; all of that belongs with qualified installers.
- Gas, solid-fuel and outdoor electrical work must be designed and carried out by suitably qualified people.
- What may be burned outdoors, and when, varies by area and must be confirmed with the local authority.
- Anything used beneath a canopy, a balcony or below habitable rooms needs professional advice before it is planned.
