Buying a Greenhouse With Installation: What Should the Quote Include?
Greenhouse buying guide
Buying a greenhouse with installation can simplify the purchase, but the phrase does not define the work included. One quote may cover delivery and assembly only; another may include a site visit or preparation while leaving the base, access or connections to you. Before comparing totals, have the exact greenhouse identified and each stage—delivery, site readiness, construction, handover and exclusions—written down. This guide explains what to ask for in a greenhouse installation quote, how to spot gaps and how to compare the scope without assuming that a product listing includes an installer or a particular service.
Quote checklist 1
What ‘installation’ means in the quote
The phrase ‘supply and installation’ sounds comprehensive, but it does not, by itself, say which tasks are covered. It may mean the greenhouse and labour to assemble it, while delivery, unloading, site preparation, base work, access equipment or packaging removal are treated separately. Ask the supplier to define where the job starts and finishes: who receives the shipment, what condition the site must be in, which components are assembled and what the installer leaves completed. Have any return visit, finishing work or supplied fixings stated as well. Also ask whether the installer is engaged through the supplier or booked separately, so you know who coordinates the handover. A clear quote names tasks rather than using a catch-all line marked ‘installation’.
Keep the product description separate from the service list. If the quote names the Prestige greenhouse with metal base, ask what that order supplies and whether any base-related work is included; the model title alone does not establish the parts, delivery or labour covered. Request distinct lines for the greenhouse, freight, site works and assembly where possible. Also identify who arranges each item outside the quote and whether it must be completed before the installer arrives. This makes a low total easier to assess: it may reflect a narrower scope, not a better like-for-like offer.
Identify the greenhouse and selected options
A quote should let both parties identify the item without relying on memory, a screenshot or a broad category label. Record the exact product or model name, any product reference shown, quantity and selected size or configuration. Where the chosen listing offers options, note the selections, such as colour, glazing or other stated details, in the same schedule. Use only the measurements shown for the item you have selected, and attach or refer to a dated order summary so the supplier’s product line and the installer’s job description match. This is especially useful if supply and installation are discussed separately or the quote is later revised.
A broad description such as ‘greenhouse’ leaves room for a mix-up. The catalogue name Bloomcabin Orangerie is a more precise reference, but it still does not confirm every item supplied. Compare the name on the quote with the exact product selection in your order summary, and ask for any discrepancy to be corrected before payment or scheduling. List accessories only if you have selected them, and mark whether each is included, supplied separately or excluded. Do not use a product photo or a general range description as a substitute for written confirmation of the chosen configuration.

Delivery, unloading and access
Delivery needs its own definition because a freight charge and an installation visit are not the same service. Ask whether the quoted amount covers transport to your address, unloading, moving the greenhouse components from the drop point to the build area and any handling equipment needed. Confirm exactly where delivery ends: at the property entrance, a driveway or another agreed spot. Tell the supplier about access constraints such as steps, narrow turns, gates or a long carry. Do not assume a delivery service will take components to the planned build area. If the installer expects the shipment to be on site before assembly, establish who receives it and how it will be protected until the booked work begins.
A line naming the Classic Plus 385 greenhouse helps match the product to the delivery booking, but it does not say where a load will be left or whether carrying is included. Ask if delivery and assembly are booked together, or if you need to coordinate them separately. Find out what happens if the access details supplied are inaccurate, the planned drop point is unavailable or components cannot be brought to the build area on the day. Confirm who must be present, what notice you will receive before arrival and whether a missed visit or extra handling changes the price. Write down the agreed delivery point and responsibilities.
Site preparation and the base
Treat site preparation as a separate work package unless the quote expressly includes it. Ask the installer for written site-readiness requirements: the area to clear, the footprint or clearances to allow for, and any surface or level conditions specified for the selected greenhouse. If a base is included, the quote should say what work is involved, who supplies its materials and who checks that the prepared surface is ready for assembly. If it is excluded, name the person or trade responsible and the date it must be finished. Clearing, excavation, levelling, spoil removal and reinstating disturbed areas should each be marked included, excluded or not applicable.
Do not assume a product name settles the base question. A listing such as T-model orangery greenhouse for a wall base identifies an item, but the quote must still say whether any wall or base work is included and what preparation is expected from you. Ask whether a site visit is needed before the supplier can confirm scope, and how an uneven, sloping or restricted area affects that plan. For site-specific questions about ground or structures, seek advice from a suitably qualified professional rather than relying on a generic quote. If a local approval or property constraint might apply, confirm it with the relevant authority or adviser.
Quote checklist 3
What the assembly work covers
Assembly should be described in practical terms, not just as a number of labour hours. Ask whether the installer is responsible for assembling the complete greenhouse or only specified stages, and whether fitting supplied panels, doors, vents, hardware and selected accessories is included where those items form part of your order. Confirm who supplies fasteners and other consumables, and whether fixing the assembled greenhouse to the prepared base is in scope. Ask what checks and final adjustments are part of the work, and whether packaging or leftover materials are taken away. A quote should distinguish assembly from site works that another contractor performs.
Keep any product name and assembly scope paired. If the quote refers to the Pyramid greenhouse for a masonry base, ask separately whether masonry construction is part of the price or must be completed beforehand; the title alone does not say who builds or prepares a base. Clarify whether the installer needs the base ready before arrival, whether they will pause if it is not, and who covers a return visit. Where the product instructions set conditions for assembly, ask the supplier or installer to confirm that the proposed work follows them. This is a scope question, not a request for you to design the base yourself.
Accessories and service connections
Separate optional equipment and service connections from basic assembly. If you have selected items such as shelving, staging, rainwater fittings, an automatic opener, lighting, heating or irrigation, list each one and ask who supplies and installs it. The quote should also state whether any plumbing or electrical work is included, excluded or to be arranged with another trade; do not infer it from ‘ready to use’. This matters when different people need to work on site in a particular order. Ask who coordinates their visits and whether connections, commissioning or testing are within the quoted scope, without assuming those services are part of the greenhouse order.
Even if the quote names the Aluminium Classic greenhouse, its product title does not establish which accessories or services you have chosen. Ask for a separate list of included fittings and an explicit note beside every item that is not included. If electrical or water work is needed, obtain a distinct scope from an appropriately qualified specialist and coordinate it with the installer; the greenhouse quote should make clear who is responsible for that coordination. Where no connections are wanted, record that too, so a later conversation cannot leave either side guessing about what was promised.

Price, GST and changes to the scope
Compare a written total that explains how it is made up. Ask whether it includes the greenhouse, freight, labour, site visit, base work, materials, travel, equipment and any agreed waste removal, and whether GST is included. These are questions for the supplier to answer, not assumptions based on a headline figure. Check the quote’s validity date, payment schedule and any conditions attached to a deposit or progress payment. If separate trades will invoice you, include those figures in your own comparison, even when they do not appear on the greenhouse quote. This gives you a realistic view of the whole project cost without treating unlike scopes as equivalent.
Compare the same selected item and location as well as the same tasks. For a quote naming the Aluminium lean-to greenhouse, ask whether the amount changes after a site visit, an access check or a change to your selection. Have the supplier explain how extra labour, materials or another visit would be priced, and require written approval before the work is added. Check what happens if an assumption in the quote proves wrong; do not rely on an informal promise that variations will be minor. A clear process lets you decide whether the quoted total is fixed for the stated scope or depends on conditions that still need confirmation.
Booking, timing and on-site contingencies
Keep the delivery date, installation booking and estimated on-site duration distinct. Ask when the supplier expects the greenhouse to arrive, how the installation date is confirmed, how long the work is expected to take and what must be ready before the crew attends. Treat estimates as estimates unless the written terms state otherwise. Confirm the notice you will receive, whether access must remain available throughout the visit and who to contact if the site is not ready. If delivery and assembly are handled by different businesses, make one person responsible for coordinating the sequence so components do not arrive without a workable plan for storing or assembling them.
Put the chosen item name, such as Aluminium Limited Edition greenhouse, on the quote and booking records so everyone is discussing the same order. Ask how delays from weather, transport, a site issue or missing or damaged components are handled, and whether the installation appointment is rebooked automatically or needs your approval. Confirm who records damage and who you contact to resolve a supply issue, and whether assembly proceeds only once the required components are available. Get the rescheduling process and any associated charges in writing; do not assume a booking moves automatically.
Quote checklist 5
Exclusions, responsibility and aftercare
Read exclusions as carefully as inclusions. A quote may omit a site visit, clearing, base construction, utility work, removal of an old structure, landscaping repair, rubbish disposal or work outside the greenhouse footprint. Ask the supplier to list exclusions specifically instead of using an open-ended phrase such as ‘all other works’. For each excluded task, identify whether you will arrange it yourself or get another trade, and whether it must be finished before delivery or assembly. Ask what happens if the installer finds a site condition that differs from the information provided. If the scope depends on assumptions, have them written down so they can be checked before you accept.
Clarify who stands behind the greenhouse product and who is responsible for installation work. Ask for the applicable product and workmanship terms, how to report an issue, the relevant contact and what documents you will receive at handover, such as assembly instructions or a record of completed work if provided. Do not assume one set of terms covers both the item and the labour; request the actual written conditions before committing. It is also reasonable to ask which business will attend and whether another contractor is involved. If a question depends on your property or local requirements, confirm it with an appropriate professional or authority rather than treating the quote as formal advice.
Compare quotes on the same scope
Put competing quotes side by side against one agreed brief: exact greenhouse and selected options, delivery address, access conditions, site-readiness assumptions, base work, assembly tasks, accessories, timing and exclusions. Mark each item included, excluded, separately priced or still unconfirmed. Compare totals only after checking GST and any separate trade costs, not simply the first number in the document. If a quote uses terms such as ‘standard installation’ or ‘complete service’, ask what they mean in actual tasks. A brief comparison table or a marked-up copy of each quote can expose gaps quickly, provided the supplier confirms any revisions in writing.
A higher total may cover work that another quote leaves to you; a lower total may rely on a base or site being ready already. Neither is automatically better or worse. Ask each supplier the same unanswered questions and request a revised scope before comparing. Choose the arrangement that matches your budget, schedule and ability to coordinate any excluded work, with responsibilities and change rules clear. Keep the accepted quote, product schedule, site requirements and any later variation together. You should be able to explain what will arrive, who will prepare the site, what the installer will do and what happens if the plan changes.
Frequently asked questions
What should a greenhouse installation quote include?
It should identify the exact greenhouse and selected options, then state whether delivery, unloading, site or base preparation, assembly and accessories are included. Ask for the handover standard, timing, exclusions, total price, GST treatment and process for approving changes. If an item is not clearly marked included, excluded or separately priced, confirm it before accepting.
Does greenhouse installation include site preparation?
Not unless the quote says so. Ask what the installer expects the site to be like when they arrive, and whether clearing, levelling, base work or removal of spoil is included. If preparation is excluded, confirm who will arrange it and when it must be finished.
Is delivery included with supply and installation?
The phrase alone does not confirm that. Check whether delivery, unloading and moving the components to the build area are included, and agree on the drop-off point. Give the supplier accurate access information and ask how extra handling or a changed delivery arrangement would affect the quote.
How do I compare two greenhouse installation quotes?
Compare the same greenhouse, options, delivery address and site conditions, then check each quote for the same preparation, assembly, accessories, timing and exclusions. Mark unclear items for follow-up and compare the complete costs, including GST and any separate trade work, rather than relying on the headline total.
What should I clarify before accepting a quote?
Confirm the site requirements, the exact work the installer will complete, who handles excluded tasks and how changes or delays are managed. Ask for payment terms and any product or workmanship conditions in writing. Keep the accepted quote and product schedule together so the agreed order and installation scope are clear.
A quote for a greenhouse with installation should let you trace the job from the selected item to delivery, site readiness, assembly and handover. When inclusions, exclusions and change arrangements are explicit, you can decide whether the price and any work you must coordinate fit your plans. The useful comparison is not the label ‘installation included’, but the written scope behind it.
