Buying a Greenhouse Direct from a Manufacturer: Questions to Ask
Greenhouse buying guide
Buying a greenhouse direct from a manufacturer is easier to assess when you know exactly who is selling it and what the offer includes. The word “direct” does not establish who will manage delivery, whether a base is included or where you turn for support. Ask about the precise model and configuration, request relevant drawings and written specifications, and have responsibilities, exclusions and charges set out in the quote. The questions below help you compare the answers before committing, without treating a product name or photograph as a complete specification.
Before you order 1
Who is selling the greenhouse, and what is included?
First establish the sales arrangement rather than relying on the word “direct”. Ask which business will take your order and appear on the quote, who actually manufactures the greenhouse, and whether those are the same organisation. Confirm who answers product questions before purchase, sends order updates, arranges freight and handles a claim if something is missing or damaged. If different organisations share those tasks, ask what each is responsible for and which contact to use at each stage. Keep the names and contact details with the quote. That tells you what support the direct route actually provides, rather than leaving you to assume one company controls the whole transaction.
Request an itemised list tied to the exact model, version and selected options. It should say what the quoted package includes, such as the frame, glazing, specified doors or vents, fixings, instructions, base or foundation, and any accessories. Ask what is optional or excluded, and request separate prices for extras and charges such as freight or installation. A listing titled Prestige greenhouse with metal foundation is not a bill of materials: ask whether the foundation is part of your quote and what the title refers to. Check that the quote and supporting product information describe the same configuration.
What to ask about the frame
Ask the manufacturer to identify the frame materials and finishes for the exact model, and to explain how the frame components are joined and which fasteners are supplied. Request a written specification that describes the parts rather than relying on a general material label. If a salesperson makes claims about strength, durability or maintenance, ask what product information supports those claims and whether it applies to the version you are considering. This gives you something concrete to compare between manufacturers and helps prevent a broad description of a product range being mistaken for details of one particular greenhouse.
Explain where you plan to put the greenhouse and ask which exposure or maintenance limits the manufacturer’s written guidance covers. If wind, snow, salt air or a particularly open site is relevant, ask what documented design information applies to that configuration and whether a suitably qualified local professional should review the site. Do not make engineering judgements from a product label alone. A listing titled Aluminium Classic greenhouse does not establish the frame’s exact specification, finish or suitability for your conditions; ask for the relevant details in writing.

Which glazing is specified?
Ask the manufacturer to name the glazing supplied with the exact model and configuration, including whether the roof, sides and openings use the same material. Request a current written specification rather than relying on a photograph or a broad phrase such as “clear panels”. If there are glazing choices, ask what differs and how the manufacturer defines any claims about light, insulation, impact resistance, weight or upkeep. That lets you compare the stated options without assuming that a familiar material performs a particular way in your garden. Ask whether any substitutions are possible and how they would be recorded on your order.
Find out how individual panes or panels are identified and whether replacement components can be ordered for the quoted version. Ask which retainers, seals or fixings are part of the specification, and whether the manufacturer provides care guidance for the glazing. A product title alone may not tell you what panels are supplied: the Aluminium wall greenhouse listing name, for instance, does not identify its glazing specification. Have the manufacturer confirm the glazing and any relevant replacement-part information for the exact greenhouse you intend to buy.
Ask for drawings for the exact dimensions
Request a dimensioned plan and elevation for the precise model and options in your quote. Ask for the overall width, length and height, and clarify which dimensions refer to the external structure and which describe usable interior space. Where relevant, check whether figures include a base, projections or other components. A drawing can also help clarify the door opening and the space needed to reach the growing area. Ask which measurement points have been used, especially where roof overhangs, gutters, handles or opening parts extend beyond the main frame. Confirm the drawing’s revision or date so you can tell whether it matches the product information and quote you have been given.
Ask the manufacturer what clearance is needed for assembly, access and routine maintenance, rather than comparing the nominal footprint alone. If doors or vents open outwards, ask what space they require; if the greenhouse will sit near a wall, fence or path, ask whether that affects access or installation. A number in a model name is not a measurement: the Classic Plus 385 title, for example, does not explain what the number represents. Use the manufacturer’s dimensioned drawing to assess the actual configuration.

Foundation and site preparation
Ask what kind of base or foundation the exact greenhouse requires, whether it is included, and which written drawing or specification describes it. Have the manufacturer identify the dimensions, attachment details and any site tolerances it specifies. Do not infer requirements from a photograph or assume that an existing paved area meets them. If the site is sloped, the ground conditions are uncertain or a new supporting structure is needed, ask what information the manufacturer can provide and whether a suitably qualified local professional should assess the site before you finalise the order.
Clarify who is responsible for preparing and checking the site, and what must be ready before delivery or assembly. Ask whether a base is an optional purchase, a separate job or part of the quoted package, and whether the manufacturer’s guidance covers the support you already have. A listing titled pyramid greenhouse for a masonry base does not confirm that your existing masonry meets the requirements or that a base is included. Ask for the exact base information and for each party’s responsibilities to be stated in the quote.
Delivery to your property
Ask what delivery means for your address. Confirm whether freight is included, where the greenhouse will be unloaded, and whether delivery reaches the property boundary, a driveway or another agreed point. Ask who unloads the packages and whether you need to arrange any handling yourself. If access is restricted, your address is rural or remote, or the route to the unloading point is difficult, describe it to the manufacturer and ask about any limits or extra charges. Package counts and outer dimensions or weights, if available, can help you plan access without assuming how the carrier will handle the consignment. Also ask whether the delivery requires someone to be present, whether packages need to be checked on arrival, and how you should record visible damage before the carrier leaves.
Ask for the current delivery estimate for your address and how you will be told about changes. Clarify how delivery is booked, which contact handles freight questions and what to do if a package is damaged or components are missing. Ask whether there is a reporting process or time window and keep those instructions with your order papers. If your quote is for the Orangerie greenhouse, or another named model, request the delivery scope for that specific order; the product name does not establish the freight arrangements or unloading service.

Who installs the greenhouse?
Ask whether assembly is self-installation, included in the offer or arranged separately. If installation is quoted, clarify exactly what the work covers and what it excludes, including any site preparation or foundation work. Find out who will carry out the installation, who you contact with questions and whether that service is part of the same order or a separate arrangement. Confirm what needs to be ready before the installer arrives and whether the quote includes any additional work you expect. Do not assume that buying from a manufacturer automatically includes assembly or that every part of the work has been priced.
Ask for the current assembly instructions for the exact model and configuration before committing, and find out how product support works if a part is missing or an instruction is unclear. If the greenhouse description refers to a wall-mounted design, ask whether attachment to an existing wall is expected and which components or work are included. A title such as T-shaped wall-mounted greenhouse is not an installation plan. Have the manufacturer clarify the supplied components, preparation required and installation responsibilities in writing.
Warranty and after-sales support
Request the written warranty terms that apply to the exact greenhouse you are quoting. Ask when coverage begins, how long it lasts and which parts or issues it covers. Clarify whether the terms address the frame, finish, glazing, replacement parts, labour and freight, and ask about any exclusions or conditions related to care, installation or site preparation. Do not rely on a verbal summary if the written terms say something different. Keeping the warranty document alongside the quote lets you compare what each manufacturer actually offers without assuming that similar product descriptions mean similar cover.
Ask how to make a claim, what information or photographs are needed, which organisation handles it and how replacement parts are obtained. If the model or a component changes over time, find out how the manufacturer identifies compatible parts for your version. A listing titled Limited Edition aluminium greenhouse says nothing about warranty coverage or future parts support. Ask for the terms that apply to the exact version in your quote, and keep the relevant contact details so you know where to direct a question after delivery.

Options and future replacement parts
If you are considering extras such as different openings, vents, shelves or other accessories, ask which choices are available for the exact model and what each option includes. Confirm whether an item is standard, optional or supplied separately, and ask for its cost and any relevant product information. If you have a particular growing plan, explain it and ask the manufacturer which configuration details matter to it. Do not assume an accessory shown in a photograph is included, or that an option mentioned for one greenhouse is available for another model.
Ask whether accessories can be added later and whether they will fit the exact version you are ordering. Check what information the manufacturer uses to confirm compatibility, whether a later addition would need separate work, and how the option affects the drawing or quoted package. If future replacement parts matter to you, ask how to identify them and who to contact for current availability. Have any selected extras marked on the order documents so the delivered configuration can be checked against what you agreed to buy.
Compare the written answers before ordering
When you compare greenhouse manufacturers, give each one the same questions and compare answers for the same intended configuration. Set the frame and glazing details beside the dimensions, base requirements, package contents, delivery, installation and warranty information. Note whether each answer is supported by a drawing or written specification, and mark anything that is unclear or still assumed. Compare whether quoted extras, freight and installation describe the same scope, rather than treating differently worded package names as equivalent. A clear, specific reply is more useful than a confident general description. If two quotes differ, ask the manufacturer to explain which inclusions or services account for the difference rather than comparing headline figures alone.
Before paying, request a final version of the quote that names the exact model and options and lists the agreed inclusions, exclusions, charges and delivery or installation scope. Ask how long that quote remains current, what the present delivery estimate is, and how changes to the configuration would be handled. Read the written payment, amendment and cancellation terms before accepting the order. If an answer could affect site suitability, package contents or support, resolve it with the relevant organisation first and keep the response with the final paperwork.
Frequently asked questions
How can I confirm whether I am buying from the manufacturer?
Ask which organisation manufactures the greenhouse and which one will accept your order. They may be the same business, but do not rely on the word “direct” or the brand name to confirm this. Also ask who will manage order updates, delivery questions and after-sales support, and keep the answers with your quote.
What documents should I ask for before ordering?
Request a specification for the exact model and configuration, a dimensioned drawing, any relevant site or base requirements, and the assembly instructions if available. Ask for the written warranty terms and an itemised quote as well. These documents let you check that the quote, product details and responsibilities all refer to the same greenhouse.
Is a foundation included in a greenhouse price?
There is no safe assumption to make from a product name or photograph. Ask the manufacturer whether a base or foundation is included in the specific quote, what it comprises and what else the greenhouse requires. If your site needs a new supporting structure, ask what information is available for a suitably qualified local professional to assess.
Who is responsible for greenhouse delivery and installation?
That depends on the arrangement in the quote. Ask whether delivery reaches your property or a particular unloading point, who unloads the packages, and whether assembly is included or arranged separately. If another company handles part of the work, confirm who to contact and what you need to prepare.
What if the manufacturer cannot confirm the greenhouse suits my site?
Ask which written design limits or site requirements apply to the exact model, and what further information the manufacturer needs. If the answer depends on conditions at your property or on a supporting structure, seek advice from a suitably qualified local professional before ordering. Do not treat a general product description as confirmation of site suitability.
A useful direct purchase is one where the product, package and responsibilities are clear before you order. Get the manufacturer’s answers tied to the exact greenhouse and keep the drawings, quote and terms together. That makes it easier to compare what is actually being offered and to spot any unanswered question that could affect your site, delivery or ongoing support.
