Buying a Greenhouse Direct from a Manufacturer: Questions to Ask
Greenhouse buying guide
Buying a greenhouse directly from a manufacturer can give you a direct route to product information, but “direct” does not settle who is responsible for the order, what is included or whether the model suits your site. Treat the conversation as a chance to get precise, written answers—not as proof that the price is lower, the lead time shorter or support automatically better. Before paying, pin down the seller, exact configuration, dimensions, site preparation, delivery, installation and after-sales terms. The questions below help you compare the offer with your plans and identify details that still need an answer.
Before you place an order 1
Confirm who is selling the greenhouse
Ask first which business will actually take the order. Is it the greenhouse maker, a retailer, an importer or an agent? Which business name will appear on the quotation and invoice, and which business receives payment? Then ask who answers product questions before dispatch, handles delivery problems and deals with warranty or replacement-part enquiries afterwards. A direct sales conversation may still involve more than one company, so establish the handover rather than assuming that the person answering an email controls every stage. Request the relevant contact details and a clear explanation of each party’s role in writing. This matters particularly if the sales contact and the delivery or service contact are different, because you need to know where an unresolved question goes.
Have the supplier identify the exact model, version, chosen options and colour or finish, where applicable, on the quotation. If your shortlist includes Bloomcabin Prestige greenhouse metal base, use that listing name to identify the product you mean; ask the supplier to confirm the configuration and included components instead of reading them into the title. The written offer should distinguish the greenhouse from separately ordered accessories, a base, delivery or assembly, and name anything you must provide. Ask how a change is recorded if a different version is proposed after the quote. Request that important answers are added to the order documents or linked to a model-specific specification.
Get exact frame and glazing details
Ask for the exact frame material and finish offered on the quoted version, rather than relying on broad labels such as “aluminium frame” or “coated”. Request the written specification for the frame, connectors and fasteners, plus any care instructions or limitations the supplier provides. For the glazing, confirm the actual material, thickness where specified, whether all panels are included and how they are retained. If there is a choice, ask what changes between the options in clarity, maintenance, handling and replacement, and whether the price refers to the same set of components. These questions let you compare documented details instead of assuming similar-looking descriptions mean the same construction. Ask whether panel replacements can be identified by a model or part reference.
Ask whether the quoted model has alternative frame or glazing configurations and which version the price describes; do not rely on a category page or image to resolve that. A name such as Aluminium Classic Greenhouse identifies a listing, but does not confirm the material specification, profile, finish, glazing or included fittings. Request a current product sheet or drawing that names the chosen options, and check that the same details appear on the quotation. If a point cannot be confirmed immediately, agree who will obtain the answer and have the document updated before comparing offers. If appearance matters, ask for finishes by written description or reference rather than judging colour from a screen image.
Before you place an order 2
Ask for a dimensioned layout
Ask for a dimensioned drawing of the exact configuration, with units and a clear note on what each measurement covers. Confirm the outside footprint and overall height, then ask for usable interior dimensions and the height where the roof meets the sides if that affects your working space. Check whether measurements include a base, frame projection or optional item; do not assume that nominal width and length describe the growing area you can actually use. A number in a product name is not a substitute for a drawing: for example, Glass greenhouse Plus 385 should be identified by its actual model documentation, not by interpreting “385”. Ask whether the drawing shows the selected door and ventilation options.
Use the plan to check the layout as well as the footprint. Ask where the door and opening panels sit, how the door operates, and what clearance is needed; then compare that with paths, fences, walls and the space needed to carry trays or tools. If you plan to add shelving, benches or watering equipment, ask which options are offered for the quoted model and how much room they occupy. The drawing should show whether your proposed arrangement leaves practical access to plants and working areas. Before setting out the base, ask the supplier to mark any missing dimensions, including space needed to get materials to the site.
Clarify the base and site preparation
Before site work, request the maker’s written base and preparation requirements for the exact model. Ask for the footprint, any level or flatness tolerances, fixing or anchoring points, and a diagram of how the frame meets the base. Clarify whether a base or fixing components are included, supplied as options or entirely your responsibility. Ask whether the instructions address surface preparation, drainage and any clearance around the perimeter. These details affect what must be ready when the greenhouse arrives; a photograph or a general promise that a level surface is enough may not answer the model-specific questions. Get the final plan before marking out or paying for work, and check that it names the version shown on your quotation.
Describe the actual site to the supplier, including any slope, existing paving, masonry, nearby wall or access constraints, and ask which requirements apply. A title such as Pyramid greenhouse for masonry bases is not a base drawing; ask for the document that specifies the intended interface and what the quoted package provides. If the site needs a new slab, masonry work, anchoring or a decision about ground conditions, have a suitably qualified builder or other relevant professional assess it against the supplier’s documentation. Avoid relying on a generic answer for site-specific foundation work. Keep the approved drawing and requirements with the order so site preparation follows the same version.
Before you place an order 3
Confirm what delivery covers
Ask exactly what “delivery” covers. Does the quoted amount take the greenhouse to your address, the property boundary or another agreed point, and does it include unloading or moving packages beyond the vehicle? Ask who arranges the carrier, what access details are needed and whether narrow entrances, soft ground or limited turning space change the plan. Request the number and approximate size of packages for the chosen configuration, plus any handling requirements the supplier can provide. A product title, including Bloomcabin Orangerie, cannot tell you the package count or drop-off arrangements. Confirm those details against your route from the delivery point to the prepared site before you agree to the order, and ask whether any part of the route is outside the delivery scope.
Get the expected delivery window and the process for changes or delays in writing, including any storage arrangements if the site is not ready. Ask what to check on arrival, how shortages or damage must be reported and whether a time limit applies under the supplier’s terms. Find out whether the driver waits while you inspect, whether a signature records receipt only, and whom to contact if a package is visibly affected. Plan for unloading only after the supplier confirms what is needed. Keep the delivery instructions with the order so the person receiving the greenhouse knows how to record a problem.
Separate installation from the product price
Do not assume assembly is part of a direct purchase. Ask whether the supplier offers installation for your address, whether it is included in the price or quoted separately, and which stages the service covers. Does it include setting out the frame, fitting glazing, hanging or adjusting the door and fitting selected accessories, or are some jobs excluded? Ask whether the base must be complete beforehand, who supplies tools and what preparation is your responsibility. If installation is not provided, request the current instructions and a parts list before committing so you can decide whether your chosen installer has the information needed. Ask for any separate installation terms, travel charges or limits on the service area in writing.
Keep the model, base drawing and installation scope aligned. If the quote identifies a T-model greenhouse orangery for wall base, ask the supplier to state which configuration and base details the installer must follow; do not treat a model title as an assembly instruction. Confirm who handles questions during assembly, how missing or damaged components are raised, and whether changes to the prepared site could create extra work. If you appoint your own contractor, give them the same model-specific documents and clarify whether installation choices affect the warranty. Agree who checks the delivery against the parts list before assembly starts.
Before you place an order 4
Read the warranty and support terms
Read warranty terms before comparing offers. Ask how long each covered component is covered and whether the terms treat the frame, glazing, finish, fittings and workmanship differently. Request the full written conditions, including exclusions, maintenance requirements and what proof is needed for a claim. Ask specifically how the supplier defines damage, wear, faults or problems connected with installation, without assuming that every issue falls under one general promise. A warranty is not a substitute for a clear description of the product or for the delivery and installation terms, so keep those documents separate. If something is important to your purchase decision, ask for the relevant clause or explanation rather than relying on a short summary. Check whether any registration or record-keeping is expected under the stated terms.
Clarify who handles a claim: the manufacturer, the business that sold the greenhouse or another service contact. Ask how to report an issue, what photographs or order details to supply, and who arranges assessment, labour, transport or replacement parts where the terms address those costs. Also ask how to identify a replacement component later; do not assume future availability. The name Limited Edition Aluminium Greenhouse does not state what is covered, so request warranty terms for the exact model and selected version. Save the quotation, specification, installation records and written answers together, and note the contact to use if the original salesperson is unavailable.
Match the greenhouse to day-to-day use
Describe what you intend to grow and how you expect to use the space, then ask which features in the quoted configuration support that use. Request clear information about the positions and operation of doors and ventilation openings, plus any optional vents, shading, shelving or other accessories you are considering. Ask what is included and what must be added, and how openings can be reached once plants and benches are in place. Conditions at the site matter too: exposure to sun, wind, rain and nearby shade can affect what you need to ask about. Request any stated site limitations for the specific model instead of accepting a broad claim that a greenhouse suits every garden. Ask how the supplied operating instructions explain routine opening and ventilation.
If you are considering a wall-side arrangement, ask for a drawing showing the intended position, clearances and any interaction with the wall, roof drainage or access. The listing title Aluminium wall greenhouse is not a siting plan and does not confirm that a particular wall, orientation or exposure will work at your property. Ask which recommendations are model-specific and which depend on the site; a professional should assess structural or building work where needed. Also ask how the layout affects everyday access for opening, cleaning and watering. If nearby trees or buildings shade part of the site, describe that when requesting guidance.

Compare complete quotations
Put quotations beside one another only after making them comparable. Match model, version, frame and glazing, dimensions, chosen options and the same level of delivery and installation service. Ask each supplier to separate the greenhouse price from delivery, unloading, base preparation, installation and optional items, and to state whether taxes or other charges are included. Compare payment stages, any deposit, quote expiry and the terms for changes or cancellation; ask rather than assuming these are identical. A direct offer is not automatically cheaper once site work and services are included. The useful comparison is the full amount you are expected to pay for the same finished scope, alongside the work and responsibility that remain yours. Also compare how each supplier resolves unanswered technical questions.
A simple comparison sheet can keep the details straight: record each specification, what is included, what is excluded, who supplies it, the stated cost and the document that confirms it. Put unanswered items in a separate column and send the same questions to every supplier. If one quote is vague about installation or delivery and another is itemised, ask the first for matching detail before concluding that the offers differ in price. Include any agreed change in a revised quotation, not just an email summary that may not be attached to the order. This method makes it easier to see whether a lower headline figure comes with more work or unresolved costs. Keep the sheet factual so assumptions do not become mistaken for agreed terms.
Resolve the final questions before ordering
Before placing the order, read the final documents as a set: quotation, model specification, dimensioned plan, base requirements, delivery and installation scope, warranty and payment terms. Check that names, selected options and any agreed changes match across them. Ask the manufacturer or seller to list the site tasks that must be finished before delivery and identify the contact for unanswered questions. If the documents conflict, ask for a corrected version; do not rely on a verbal promise to resolve a mismatch later. A supplier’s answer is useful when it is specific to your chosen version, supported by a drawing or term where relevant, and clear about who will do the work. Save one final copy that everyone involved can refer to.
Finally, decide whether the whole arrangement suits your growing plans, available space and ability to prepare and maintain the site. Be cautious about proceeding while key details remain unclear—for example, if no one will confirm which business is responsible, what base is required, how delivery reaches the site or how a claim is handled. You do not need every possible accessory decided immediately, but the items affecting fit, cost and installation should be settled before commitment. If a decision depends on the ground, structure or construction at your property, use a qualified local professional alongside the manufacturer’s written information. A well-defined order gives you a realistic view of the work still ahead and a better basis for choosing between offers.
Frequently asked questions
What does “direct from a manufacturer” mean for my order?
Ask whether the business making the greenhouse is also the business named on your quotation and invoice. If an agent, importer or retailer is involved, find out who takes payment, arranges delivery and handles warranty or parts enquiries. Direct contact alone does not define those responsibilities.
Which details should the written quotation include?
It should identify the model and configuration, frame and glazing choices, dimensions or the drawing they refer to, options and exclusions, delivery and installation scope, costs, payment terms and warranty documents. Ask for the current documents to match the quoted version rather than relying on a general catalogue page.
Should I prepare the base before ordering?
First get the exact base plan and preparation requirements for the chosen model, then compare them with your site. If the work involves foundations, masonry, a slope or structural decisions, ask a suitably qualified local professional to assess it. Avoid beginning from a generic sketch or guessed dimensions.
Is installation included when I buy direct?
Only if the quotation says so. Ask whether installation is available for your address, what tasks it covers, what the price includes and what you must complete first. If using your own installer, request the current assembly documents and ask whether the warranty terms set any conditions.
What should I do if a delivery is damaged or incomplete?
Follow the supplier’s written receiving and reporting process. Before ordering, ask what to inspect, whom to contact, what evidence is needed and whether a reporting deadline applies. Keep the delivery record and photographs of any issue, and do not assume a driver’s signature settles a later query.
Your best comparison is not simply who makes the greenhouse, but how clearly each seller connects the exact product to the work around it. When the model, site requirements, delivery, installation and support are documented, you can judge both what you are buying and what remains your responsibility. If information affecting fit, cost or warranty is incomplete, let that unanswered question guide whether you are ready to commit.
