Buying a Greenhouse with Installation: What Should the Quote Include?

GREENHOUSE BUYING GUIDE
An installation-inclusive greenhouse quotation can still leave important work outside the total. One supplier may price the structure and assembly, while another also includes delivery to the growing area and preparation of the base site. The headline amount is meaningful only when the quotations describe the same greenhouse, the same work and the same handover point. Before paying a deposit or accepting a date, ask for a written breakdown that names the model, assigns each task, lists exclusions and explains how changes, access problems and payment are handled. This guide focuses on the order and installation scope, rather than the skills or tools needed to build a kit.

Quote checklist 1
Identify the greenhouse and configuration
Have the quotation name the exact greenhouse model and configuration, not just “greenhouse” or a broad material description. It should identify the selected size and options using the supplier’s product documents, and state which document defines the order. If the chosen item is the Bloomcabin Prestige Greenhouse Metal Base listing, put that catalogue identity in the quotation; its name does not show whether delivery, a base or assembly is included. Matching the order reference to the installation price prevents one supplier from costing a different version or package from another. Ask for a corrected quotation if the product reference and installer’s job sheet use different labels. Retain the quotation revision number with the order confirmation, so later changes can be checked against the version on which you made your decision.
Check that the supply schedule matches that configuration. It should refer to dimensions and options stated in the product documentation, and identify materials, glazing or included components only as the supplier documents them. Do not use an abbreviated name or a number in a model title as a substitute for the actual specification. Ask the supplier to reconcile any difference between the listing, quotation and installer’s job sheet in writing. If substitutions are possible, record who may authorise one and whether it changes the price or timing. This ties the assembly labour to the greenhouse actually ordered, rather than an undefined “standard” model.
Separate the greenhouse price from service costs
Ask for the greenhouse supply, delivery, unloading or carrying, site preparation, assembly labour and any extras to be separately priced or clearly identified within a package. Separate figures make omissions easier to spot; a bundled line can still work if a schedule explains it. The Bloomcabin Orangerie listing is a specific catalogue name to record, not evidence that transport or assembly is included. If one supplier’s “installation” line covers more work than another’s, ask both to define their terms before comparing totals. Include any third-party work you will need to arrange so its cost does not disappear from your comparison.
Look for a clear subtotal and final amount, any applicable tax treatment, the quotation’s validity period and the status of optional work. If the supplier includes an allowance for preparation or access, ask what assumptions it is based on, what could increase it and how extra work would be priced. Distinguish confirmed amounts from estimates or conditional charges; an allowance is not automatically comparable with another supplier’s confirmed price. Check whether listed extras are included in the total or await approval. The breakdown should show both the likely overall cost and any uncertainties that remain. It should also make clear whether a change requires your written approval before it becomes an additional charge.
Quote checklist 2
Pin down the delivery point
Specify the delivery address and the agreed drop-off point. “Delivered to site” may leave it unclear whether the service ends at the entrance, on a driveway or closer to the prepared growing area. Ask whether unloading and moving the goods from the vehicle to that point are included, who provides any carrying help, and whether packaging is removed. If the quotation names the Glass Greenhouse Plus 385 listing, treat that as the product reference, not a promise that a particular route, unloading method or delivery service is covered.
Tell the supplier about practical access conditions at the address, including any gate, shared access or restricted stopping point. Ask whether delivery and installation are booked together or separately, and what happens if one has to move while the other remains scheduled. Confirm how you will be notified of the delivery window and who to contact if the vehicle cannot reach the agreed point. If the goods are to be left somewhere before assembly, clarify who is responsible for that arrangement rather than assuming the installer will handle it. Consider whether the proposed temporary storage area is available on the planned date and whether it keeps the delivery route clear for the later visit.
State who prepares the site and base
“Site preparation” can mean different things in different quotations. One may cover clearing the area, while another may include levelling, excavation, constructing a supporting base or removing spoil. Ask for the specific tasks, the person or business responsible for each one, and whether any materials are included. Do not assume that preparation is part of the greenhouse price or the assembly charge. Where groundworks or base design are involved, confirm the requirements through the relevant product documentation and an appropriately qualified professional; a general installation price is not a design specification. Record any agreed site condition in plain terms, rather than relying on a vague statement that the area must simply be “ready”.
Ask what the installer considers a ready site and how that will be confirmed before work begins. If you are arranging a base separately, find out what information the installer needs and whether they will check it before the scheduled visit. A quotation referring to the T-model greenhouse orangery for wall base listing should still say what supporting wall or base interface is required and who provides it; the catalogue label does not establish that an existing surface is suitable. Agree how any change to the preparation plan will be discussed and priced before the work proceeds.

Quote checklist 3
Check the route into the garden
Access assumptions can affect the delivery and labour scope, so describe the route from the stopping point to the greenhouse site. Note gates, narrow passages, steps, changes in level, long carrying distances and any obstacles that may prevent a clear path. Ask the supplier which measurements or photographs would help them assess the route, rather than guessing what can be moved through it. For a quotation naming the pyramid greenhouse for masonry bases listing, the product label still does not settle the delivery route or confirm the condition of a base you already have.
Ask whether a site visit is needed to confirm access before the price is finalised. If the quotation depends on a particular unloading point or unobstructed route, have that assumption written down. Find out what happens if the site differs from the information supplied: could there be additional labour, a return visit or a rescheduled installation? Ask how any extra charge will be explained and approved before the work changes. Sharing accurate access details early is more useful than relying on a broad note that delivery is “to site”. Recheck the route shortly before delivery if temporary obstructions, building work or changes to parking could affect the agreed plan.
Describe exactly what assembly includes
Ask the installer to describe the assembly work covered by the price, rather than relying on a general phrase such as “full installation”. Depending on the selected configuration, the scope may need to identify work on the frame, panels, doors, vents or other listed components. Ask whether any fitting or securing to the prepared base is included, if the product instructions call for it, and what work is left to someone else. If the quotation refers to the Aluminium Classic Greenhouse listing, the labour should be tied to the configuration being ordered, not an unspecified standard build.
Clarify what happens at handover. Ask whether the installer checks the listed components with you, removes packaging or offcuts, and explains how missing or damaged items should be reported. If any part of the greenhouse is to be completed by a different contractor, identify where the installer’s work ends and that contractor’s work begins. A written handover point helps prevent disagreement about whether an unfinished task was included. It also gives you a record of the work the assembly charge was intended to cover. If you cannot be present, agree in advance who may receive the handover information and how any observations will be recorded.
Quote checklist 4
List exclusions and assign responsibility
Ask the supplier to state what is excluded, not only what is included. Depending on your plans, exclusions might concern groundworks, removing spoil, repairing disturbed landscaping, clearing the access route, packaging disposal or any requested electrical or water work. Do not assume these tasks are part of greenhouse assembly. A quote naming the Aluminium Wall Greenhouse listing still needs to allocate any relevant wall or base preparation; a catalogue name does not define who carries out that work.
For every excluded or separately priced task, record who will arrange it: you, the greenhouse supplier, the installation contractor or a third party. Make sure the person responsible knows when the work must be finished and what the installer needs before arriving. Ask how a newly identified task will be described, priced and approved, especially if the installer finds a difference between the site and the information supplied. This makes the boundary between included work and extra work clear before a decision is made, rather than leaving you to resolve it during installation. It also helps you identify work that needs to be scheduled before delivery rather than after the installation team has arrived.
Agree dates, dependencies and payment terms
Ask the supplier to explain the expected sequence for order confirmation, delivery, site preparation and assembly. The quotation should distinguish a target period from a confirmed appointment, and say what needs to happen before an installation date can be set. If work depends on a completed base, access check or another contractor, record when that dependency will be reviewed. With the Limited Edition Aluminium Greenhouse listing, as with any model name, the catalogue label does not state a delivery lead time; ask the supplier to put the relevant timing information in writing.
Read the payment terms alongside the work schedule. Confirm the amount and due date for any deposit, when later payments are due, and whether each payment relates to a clear stage of the order. Ask how changes to delivery or installation dates affect the agreed payment schedule, and whether the greenhouse and installation are invoiced separately. Check the final amount against the quotation and its listed conditions before paying. Clear dates and milestones reduce uncertainty without requiring you to assume a particular payment practice. Keep copies of the accepted quotation and payment records together, especially where the supply and installation services are billed by different parties.

Quote checklist 5
Compare quotations on the same scope
Set out the quotations side by side and compare the same points for each: greenhouse identity and configuration, supply amount, delivery destination, unloading, site preparation, assembly, exclusions, timing and payment terms. Note whether each item is confirmed, conditional or left unanswered. If one quotation combines several services, use its attached schedule to identify what the combined amount covers. This comparison is more revealing than placing two headline totals next to each other, because it shows which tasks you would still have to arrange and which assumptions differ. A simple comparison sheet can make it easier to spot a missing service before an apparently lower total influences the decision.
When a quotation is unclear, ask its supplier to amend or explain it rather than filling in the gaps yourself. Request the same information from each supplier so you can compare equivalent work. A higher total may cover tasks that another quotation leaves out, while a lower total may depend on preparation or access you must organise. The useful comparison is between the greenhouse and services you will actually receive, plus the work and costs still assigned to you—not between prices that use the same word for different scopes.
Get the final scope in writing
Before accepting a quotation, make sure its latest version identifies the greenhouse, selected configuration, delivery address and agreed work. Ask the supplier to attach or identify the product documents used for the order and include any schedule or site notes that affect the price. Check that the written version reflects any answers given about the base, access, exclusions, dates and payment. If more than one contractor is involved, record each party’s task and the point at which responsibility passes to the next person.
Keep the process for changes clear as well: who may request a variation, how its cost and timing will be set out, and how approval will be recorded. If a condition remains unresolved, ask for it to be addressed in the quotation before you commit rather than relying on a verbal assumption. A complete written scope makes the purchase easier to assess because you can see what will arrive, what installation covers and what you still need to organise. Keep the final accepted version and any agreed amendments in one place so that the delivery and installation teams are working from the same information.
Frequently asked questions
Does an installation quote automatically include the greenhouse base?
No. “Installation included” does not specify whether the base is supplied, built or prepared, or whether you need to arrange that work separately. Ask for each base-related task to be named, with responsibility assigned to the supplier, installer or you. If the base design or groundworks are uncertain, get advice from an appropriately qualified local professional.
Is a single all-in price enough to compare quotations?
Only if a written schedule explains what the price covers. Confirm the exact greenhouse and configuration, delivery point, site preparation, assembly, exclusions and any conditional charges. Without that detail, two totals may include different work. Ask for an itemised breakdown or a clear scope attached to the quotation before comparing them.
What access information should I give the installer?
Share the delivery address and describe the route from the vehicle’s stopping point to the planned greenhouse site. Mention gates, narrow passages, steps, level changes, long carrying distances and parking limitations. Ask which measurements or photographs the installer needs, and whether a site visit is required to confirm the quotation’s access assumptions.
Who should prepare the site for the greenhouse?
The quotation should say whether the supplier, installer, you or another contractor is responsible for each preparation task. Ask what the finished site must be like and who checks it before installation. For questions about designing a supporting base or carrying out groundworks, consult an appropriately qualified professional rather than relying on an undefined installation allowance.
Can delivery and assembly take place on different days?
They may be scheduled separately, so do not assume they happen together. Ask for the planned sequence, who contacts you to confirm each date and who is responsible if delivery or installation is delayed. If the greenhouse arrives first, clarify who is responsible for storage, and whether a separate visit or return trip affects the price.
An installation quotation is easiest to assess when the greenhouse identity, each phase of work and every handover point are written down. Compare what you will receive with what you still have to organise, including site readiness, access and any third-party work. If an assumption is missing, have the supplier clarify it in the revised quotation before accepting. A total becomes comparable only when responsibilities, timing and payment terms are clear.
