Buying a Greenhouse With Installation: What Should the Quote Include?
GREENHOUSE BUYING GUIDE
Buying a greenhouse with installation can combine several distinct costs and responsibilities: the structure, delivery, preparation of the site and assembly. The word installation alone does not tell you which of these are included, or whether the installer expects the site to be ready. Before choosing an option, ask for the greenhouse and the work to be identified in writing, with assumptions and exclusions beside the total. Comparing quotes on that same scope makes it easier to spot a missing task rather than treating the lowest headline figure as a like-for-like offer.

What a greenhouse installation quote needs to identify
Ask the supplier to identify the greenhouse by its full model name and selected options, then distinguish product supply from transport, site work and assembly. The quote should show the installation address and total, while spelling out the main inclusions, exclusions and optional items. If it uses one package price, request an attached scope or itemised schedule; a one-line figure does not show whether two proposals cover the same job. Check how tax is treated and whether allowances or stated assumptions can change the amount. Where different businesses supply the structure and do the work, ask who is responsible for each part and who co-ordinates them.
Read the terms for quote expiry, payment stages, booking or start dates, and how changes are approved. They form part of the decision even when the greenhouse and labour look clear. Ask whether the amount depends on an uninspected site, clear access, a pre-existing base or a particular delivery arrangement. If so, have that assumption written down and ask what happens if it proves inaccurate. The document should identify who to contact about supply and installation, especially if separate businesses are involved, and say who co-ordinates the handover. Keep the quote date and version with any revised offer.
The greenhouse and the items included in the price
A detailed supply description helps prevent a difference between the greenhouse you chose and the one priced. Ask the quote to name the structure and list the components being supplied, such as the frame, glazing or panels, doors, vents, handles, fasteners and any base, foundation parts, gutters or accessories selected. Treat this as a request to identify the package, not a reason to assume every item comes as standard. If the listing offers configurations or options, have the chosen version recorded clearly, including any finish or opening arrangement that matters to you. Ask whether optional shelves or other additions are included or priced separately.
A product title such as the Prestige greenhouse with metal foundation identifies the item under discussion, but does not on its own define the parts in your quoted package or the labour covered. Check that the quote refers to the same product or model identifier as your order, and that selected extras appear in both documents. Ask who checks that all supplied components are present before assembly starts, and how missing or damaged parts are recorded and addressed. Keeping the supply list attached to the installation scope is useful if the order confirmation uses a shortened name.

Delivery, unloading and access to the site
Freight and installation are different parts of the job, even where one supplier arranges both. Ask whether delivery is to the property boundary, kerbside or a particular drop-off point, and whether unloading and moving the package to the greenhouse location are included. Confirm what vehicle access and assistance the quote assumes, who will be there to receive the delivery, and whether extra handling is priced separately. The quote should show the delivery destination accurately and say where the goods will be left. Check whether installation follows on the same visit or is booked separately.
Give the supplier relevant access details before accepting: narrow gates, steps, low branches, steep or soft ground, a long carry from the drop-off point, restricted parking or limited turning space may affect how goods can be moved. Do not assume these details have been assessed just because the address is on the quote. Ask whether a site visit or photos are needed, and what happens if the route differs from the description. For a Bloomcabin Orangerie, as for any named greenhouse, have the delivery paperwork identify the same model and location as the installation quote. This avoids a vague reference to a greenhouse when several items are being ordered.
Site preparation: what happens before assembly
Site preparation can mean anything from clearing the chosen area to substantial ground or building work, so the quote should define its boundary. Ask who checks the proposed footprint and existing surface, whether levelling or removal is included, and whether drainage, access or moving existing items is part of the job. Clarify who must clear the area and when it needs to be ready. The installer may expect you to provide a prepared location; if so, request the requirements in writing. A quote for assembly alone is not confirmation that the ground or an existing structure has been assessed for suitability.
If the chosen greenhouse is described as wall-mounted, clarify who checks the proposed wall and location and what condition must be confirmed before work begins. The product name T-model wall-mounted greenhouse orangery can identify the item, but it does not say whether a site inspection, wall repairs or other preparation are included. Ask whether the installer needs measurements, photographs or a visit, and whether the quote assumes the wall is already suitable. Where ground or building suitability needs technical judgement, ask an appropriately qualified professional rather than relying on a vague note such as site ready.

Foundations and fixing: identify who supplies the base
Foundation and fixing work deserve their own line in the scope. Ask what support or base the greenhouse requires according to its supplier's instructions, whether that item is supplied with the greenhouse, and who prepares, constructs or provides it. The quote should say who is responsible for fixing the structure to the agreed support and supplying the relevant parts; do not infer either from a model name or from a broad phrase such as full installation. If you already have a slab, masonry base or other support, have its condition and suitability confirmed by the responsible professional before treating it as ready.
The name Pyramid greenhouse for masonry base can help identify a product, but the quote still needs to say whether a masonry base is supplied, built by the installer or expected to be in place before arrival. Clarify any excavation, demolition, disposal, anchoring or repair work, and who arranges it. Ask how the installer confirms the base is ready, what requirements must be met, and what happens if the existing surface does not meet them. Avoid relying on a spoken understanding about dimensions or condition: have the relevant requirements recorded and seek professional advice if suitability is not straightforward.
Assembly: define the installer's work
Assembly needs a task-by-task description, not only the word fit. Ask which supplied parts the installer will assemble, whether glazing or panels, doors, vents and included accessories are fitted, and what finishing or adjustment is included. Confirm whether the crew will check parts before assembly, bring its own tools and materials, and remove packaging or offcuts at the end. These are questions to settle, not standard inclusions to assume. Also clarify whether the work will be done by the quoted provider or a subcontractor, and who remains your contact if a component or assembly issue is found.
A quote naming the Aluminium Classic greenhouse should still state what assembled means for that order. Ask whether the installer will carry out final checks and a handover, or whether those tasks are excluded; do not infer a completed setup from the product name. If you expect a demonstration of doors, vents or other supplied components, put that in the scope. Record what you need to provide on the day, whether someone must be present, and how completion is confirmed before the installer leaves. Agree where to report a concern noticed during that handover.

Exclusions, extra work and price changes
Exclusions should be explicit enough that you can see what remains your responsibility. Items to clarify include clearing the site, removing an old structure, disposing of packaging or soil, foundation construction, repairs to an existing wall or base, access equipment, reinstating disturbed landscaping, and connecting electrical, water, heating or irrigation services. This is not a claim that these tasks are needed for every greenhouse; it is a prompt to ask about anything your plan requires. If an item is not included, ask whether the provider can quote for it or whether you need another contractor.
An item described as an Aluminium wall greenhouse still needs a clear installation boundary: the name does not establish whether a wall is inspected or prepared, or whether the quote covers fixing work. Ask the supplier to list excluded work and identify optional extras separately, with their cost or the basis for pricing them later. Agree in writing how a change is authorised if the installer finds an unforeseen issue, including whether work pauses while you decide. This helps you avoid being asked to approve an undefined addition on the day.
Timing, payment and responsibility for the order
Ask how the order and installation fit together. The quote can set out the expected sequence for supply, delivery, site preparation and assembly, and identify what has to happen before a date can be confirmed. Check whether the greenhouse arrives before the installer, who is responsible for storage in that interval, and how a delay caused by site readiness, delivery access or weather is handled. Avoid treating a broad estimate as a firm appointment unless the document says so. If you need the work within a particular period, ask which dates are commitments and which depend on other steps.
Read the stated payment schedule, deposit arrangements, quote validity and cancellation or rescheduling terms before placing the order; ask for any unclear point in writing. Confirm what happens if you change the model or selected components after the quote is prepared. For example, if your order names the Classic Plus 385, the quote should identify that same option and explain how a substitution or change affects the agreed supply and installation scope. If product or workmanship cover is mentioned, request the written terms and who handles questions about each; do not assume they are identical or included in the same way.

How to compare greenhouse installation quotes
Compare offers against the same greenhouse, configuration, delivery address and site description. Check the product total, transport, unloading, base or fixing work, assembly labour, excluded jobs, taxes and optional items side by side. A quote with a lower total may simply leave one of these out, while a package price may include items another supplier lists separately. A model name such as limited edition aluminium greenhouse identifies what an offer refers to; it does not make two scopes equivalent. Compare what each provider will do and supply, not just the headings or the amount at the bottom.
Then check the assumptions beneath each figure. Are the same components included? Is site preparation based on the same information? Does either quote rely on a visit, photos or a future measurement? Are possible extra tasks priced, excluded or left undefined? Ask providers to clarify vague terms such as standard assembly or ready site, and to separate required items from optional additions. If a revised quote changes the scope, compare the revision rather than relying on an earlier total. This like-for-like review shows where offers differ without requiring you to guess what a trade term means.
Questions to resolve before accepting the quote
Before accepting, read the quote alongside the product order and confirm they describe the same model, options, delivery address and site conditions. Check that each responsibility has an owner: who supplies the greenhouse, who receives and unloads it, who prepares the location and base, who assembles it, and who removes any agreed waste. Note any task you will complete yourself and the deadline for doing it. If a drawing, plan or site photo matters to the scope, ask for it to be attached or referenced so both sides are discussing the same location.
Resolve open questions before the order is placed: what exactly is supplied, what does assembly include, what is excluded, what must be ready, and how are added costs approved? Ask for a written response if the quote uses general wording or relies on a conversation. If the supplier needs a site visit or professional assessment to settle a point, find out whether the quote is provisional and what will be confirmed afterwards. Keep the accepted version with the order confirmation. When those answers are clear, you can judge whether the package fits your site, budget and appetite for arranging separate work.
Frequently asked questions
Does installation include preparing the site or building a base?
Not necessarily. The word installation does not define site preparation or foundation work. Ask whether clearing, levelling, base construction and fixing the greenhouse are included, and who is responsible for anything left out. If you have an existing surface, clarify who will assess whether it is suitable.
Should delivery and assembly be listed separately?
Separate lines make a bundled quote easier to understand and compare. Check whether the delivery price covers unloading and moving the parts to the chosen location, and whether assembly happens at the same visit or is arranged separately. The quote should state what each amount covers.
What information should I provide when requesting a quote?
Give the supplier the greenhouse model and options you are considering, the delivery address and a clear description of the proposed location. Include relevant access details and explain what surface or base is already there. Ask whether photos, measurements or a site visit are needed.
How can I compare two installation quotes fairly?
Check that both quotes cover the same greenhouse, options, delivery address and site conditions. Compare supply, transport, unloading, site and foundation work, assembly, exclusions, tax and optional extras. Ask about vague terms and assumptions before treating the totals as like-for-like.
What if the installer finds that my site is not ready?
Before accepting, ask how the provider will handle a site that differs from the description or is not ready for assembly. Clarify whether work pauses, who decides what needs to change, and whether a new visit or extra work affects the timing or cost. Get the process in writing.
The most useful installation quote is not necessarily the longest or the cheapest. It is the one that matches the greenhouse you want, describes the work to be done at your site and makes the remaining tasks clear. With delivery, preparation, assembly and exclusions set out in writing, you can compare the full scope and decide whether the arrangement suits your plans.
