Buying a greenhouse with installation: what should the quote include?
GREENHOUSE BUYING GUIDE
Buying a greenhouse with installation can make the project easier to coordinate, but the phrase “installation included” does not tell you what the price covers. It may mean assembly only, while delivery, the base, site preparation or work around an adjoining wall is priced separately. A useful quote connects a clearly identified greenhouse to a defined delivery and fitting service, lists what you must prepare, and explains what happens if site conditions differ. Use the same checklist for each offer so the totals are genuinely comparable before you accept.
Quote checklist 1
Separate supply, delivery and fitting costs
Ask for a written, itemised quote rather than a single figure described as a fitted greenhouse. It should name the seller and the party carrying out the installation, then say who handles product questions, delivery changes and fitting issues. If two businesses are involved, ask where their responsibilities meet: who confirms that the base is ready, who coordinates delivery with the fitting date, and who contacts you if a component is missing? Request a named contact for each part of the order, especially where the seller arranges a separate installer. The handover should be clear in the paperwork, not left to assumption.
Request separate amounts, where possible, for the greenhouse, selected options, delivery, assembly and base or other site work. Ask for the total payable and whether VAT, travel, unloading, waste removal or other charges are included or will be added. “Installation included” can mean different things: one quote may cover assembly only, while another may include anchoring; base preparation may be excluded from both. Ask each provider to define its wording and list the work covered. Record the quote date, expiry date and whether the price is fixed for the stated scope or remains an estimate subject to a site check.
Name the exact greenhouse and options
Record the greenhouse’s full product name and reference, exact variant, selected finish and options in the quote. Ask the supplier to confirm the specification from current product documentation, including frame and glazing details, panel type, door and vent arrangement, and included fittings. A listing title or photograph is not a schedule of what will be supplied. Use the Prestige greenhouse listing as an identity reference, for example, then make sure the quote states which version and extras are included rather than relying on a shortened name. If several sizes or configurations are offered, have the chosen one described explicitly.
Have the seller and installer refer to the same specification and drawing. If the quote says “standard glazing” or “standard accessories”, ask for the exact items or the document version that defines them. Note anything you have chosen separately, such as additional vents or a different door arrangement, and state whether it is included in the sum. If the offer is revised, request a new version with the changes and updated total; this prevents an earlier option from being mistaken for the final order. Make clear which items shown in product images are not part of the selected package.
Quote checklist 2
Confirm dimensions, position and access
Check the quoted dimensions against the supplier’s current drawing for the exact model and variant. Ask whether measurements refer to the outside footprint, the frame or another point, and note the overall height and space needed for doors to open. A product label alone cannot settle these details; even the Orangerie greenhouse listing should be connected to the dimensions of the version actually being ordered. If a plan is available, attach it to the quote or identify its revision so the seller and installer are working from the same information. Ask how a later measurement change will be handled.
Confirm the precise position on the plot and the route the delivery team and installer will use. Check narrow gates, turns, steps, overhead restrictions and the distance from the unloading point to the prepared base. Tell the supplier about slopes, obstacles, trees, fences or nearby buildings that could affect access or assembly. Leave room to reach the doors and carry out routine work around the greenhouse, not just to fit its footprint. Agree who verifies the measurements and signs off the location. If nobody has visited, ask what measurements or photographs are needed and who is responsible if the information proves incomplete.
Define the base and site preparation
Ask for the base requirements in writing and distinguish the greenhouse base from the groundworks that create it. The quote should say whether it includes a base supplied with the greenhouse, a prepared surface, or the labour and materials to make a base; do not assume one follows from another. A product name such as the pyramid greenhouse for masonry bases listing is a reason to confirm the manufacturer’s stated requirements, not proof that masonry work or any other foundation is part of the fitting price. Ask for the relevant installation instructions or drawing to be identified.
Define “site ready” for this particular installation. Ask who removes turf or old paving, clears plants, deals with spoil and leaves the area level and accessible, where those tasks are needed. The installer should state the base and preparation requirements taken from the manufacturer’s instructions; avoid accepting vague wording such as “suitable base by customer”. If a separate contractor is building the base, pass on the greenhouse supplier’s requirements before work begins. Clarify whether the installer will check the base on arrival and what happens if it is not ready.
Quote checklist 3
Set out delivery and unloading arrangements
Clarify what delivery means at your address. The quote should identify the delivery charge, destination, unloading arrangements and whether materials are left at an agreed point or carried closer to the installation area. Do not assume the crew will move packages through a house, garden gate or long route. For an order such as the Classic Plus 385 greenhouse listing, ask the seller to confirm arrangements for your address and the exact item, including any access limits or equipment you must provide. Tell the supplier about restricted access or parking before the delivery is booked.
Agree how delivery and fitting dates will be coordinated, who needs to be present and how you will be notified of a delay. Ask whether materials can be held until the site is ready or, if delivery comes earlier, who is responsible for secure storage before assembly. Make sure the quote states whether packaging is removed and taken away or left for you to handle. On arrival, follow the supplier’s process for checking the order against its documents and reporting missing or damaged items. Ask for those instructions before the delivery crew leaves.
Describe the installation work
Ask the installer to itemise the work included in assembly. Does the price cover erecting the frame, fitting glazing, doors and vents, and attaching selected accessories? Are anchors or fixings included, and is fitting them part of the agreed work? The answer should match the chosen model and its instructions, rather than rely on an undefined term such as “standard fit”. For a wall-based design, such as the T-model wall-based greenhouse listing, ask who, if anyone, prepares or finishes the junction with the existing building. Do not assume that surrounding building work is included in greenhouse assembly.
Ask what the crew will do at the end of the visit. A useful scope says whether the installer checks that doors and vents operate, collects packaging, removes offcuts and leaves the work area tidy; confirm which of these tasks are included. Request an expected number of visits or a time window, while recognising that the arrangement may depend on site readiness and delivery. If the crew encounters an issue that prevents completion, find out who will explain the problem, price any extra work and agree a return visit. Ask how your approval will be obtained before additional charges are incurred.
Quote checklist 4
Assign site responsibilities and variations
Put customer and installer responsibilities in separate lines. You might need to clear access or arrange a prepared base; the installer may need a clear route, confirmed dimensions and particular site conditions. These are tasks to allocate, not assumptions about every job. Whether the chosen greenhouse is the Aluminium Classic greenhouse listing or another model, request preparation instructions that apply to that exact design and identify any task outside the fitter’s scope. If nobody has visited, the quote should state what information its price relies on and who supplied it.
Ask what happens if the description proves wrong: the route is narrower than reported, the base needs attention or an obstacle prevents assembly. The quote should explain how the installer records a variation, prices extra labour or materials, and seeks your approval before proceeding. Confirm whether a return visit, extra travel or rescheduling can carry a charge, and how that charge will be agreed. If the figure depends on a survey, ask what condition will make it firm. Do not compare it directly with a fully scoped price without allowing for that uncertainty.
List exclusions and optional extras
Read exclusions as carefully as included work. Ask whether staging, shelving, extra vents, automatic openers, water collection, heating, lighting, paving, drainage, landscaping and removal of old structures are included, optional or outside the quote. These are items buyers may want to clarify, not features every greenhouse needs. A lean-to greenhouse listing is a prompt to ask whether work to the adjacent wall or surrounding building is excluded; the greenhouse price alone does not describe alterations to a property. Have any extras you want priced separately before ordering.
Check whether listed amounts include VAT, materials, delivery, travel, access equipment, waste handling and any subcontracted work. Ask for a clear total and an explanation of conditional allowances. A provisional amount can leave the final cost open, so find out what it covers and how a change is agreed. The quote should also state how long it is valid, whether options or charges may change after that date, and what payment or cancellation terms apply. If planning permission or another approval could affect your project, establish whether checking it is outside the supplier’s scope and seek guidance from the relevant authority or a qualified professional.
Quote checklist 5
Agree dates, payments and aftercare
Get the proposed sequence in writing: order confirmation, delivery, site preparation, installation and any follow-up visit. Ask for a date or date range, what depends on a ready base, and how changes are handled if delivery and the installer are booked separately. An order for the limited-edition aluminium greenhouse listing, like any other selected product, should identify the exact version on the confirmation so a delivery query can be matched to the right item. Treat an indicative window as different from an agreed appointment, and avoid arranging dependent work until responsibilities and dates are clear.
Ask for the payment schedule, including any deposit, stage payments and when the balance is due, then check which items each payment relates to. Request any product warranty and installation-workmanship terms in writing, including who to contact if a component is missing, a part is damaged or fitting needs attention. Do not assume one party handles every issue when supplier and installer are different; ask them to explain the process in their documents. Keep the accepted quote, specification, drawings, delivery record and messages about changes together so the order can be checked against what was agreed.
Compare the written scopes before accepting
Compare quotes line by line, not just by headline total. Match the exact greenhouse and options, dimensions, base work, delivery point, access assumptions, assembly tasks, waste removal, VAT, schedule and payment terms. Mark every item as included, excluded, optional or conditional. If one quote is lower, ask whether it omits a base or site work, delivery carrying, anchoring or removal; request a priced amendment so you can compare the same scope. Providers need not use identical methods, but you should be able to see what each one will supply and do.
Before accepting, read the quote alongside any product specification, drawing and installation terms it refers to. Check that the name, version and options agree across the documents, and have missing answers added to a revised quote or order confirmation. Pay particular attention to points that affect the site: who measures, what “ready” means, how variations are approved, and who coordinates delivery with fitting. If a key question remains open, ask for it to be resolved before treating the price and schedule as agreed. That gives you a clearer basis for judging whether the package suits your site and budget.
Frequently asked questions
Does an installation quote automatically include the base?
No. “Installation” may refer to assembly only. Base supply, groundworks, levelling and preparation can be priced separately. Ask the supplier to say who provides the base, what preparation is required and which tasks are included in the fitting price. Count a task as included only when it appears in the quote or a document the quote clearly refers to.
Is a site visit needed before I accept a quote?
Not always, but a visit can help identify access, measurements and site conditions before work is scheduled. If the supplier quotes without seeing the site, ask which measurements and photographs it has relied on, what assumptions it has made, and how the price or fitting date could change if those assumptions prove wrong.
What does “installation included” cover?
The phrase has no single scope. Ask whether the price covers frame and glazing assembly, doors and vents, selected options, fixings, final checks and packaging removal. Confirm whether delivery to the installation area and a prepared base are separate. The answer should apply to the exact greenhouse and variant you are ordering.
What if delivery and fitting are handled by different companies?
Each party should confirm its role in writing. Establish who coordinates delivery with the fitter, who takes queries about missing or damaged components, and who handles an installation issue. Ask for named contacts and an agreed handover rather than assuming one company will manage the other’s work.
What happens if the site is not ready on the fitting date?
Ask the installer to explain the issue and set out any extra work or cost in writing before proceeding. Clarify in advance whether a return visit, storage or rescheduling can carry a charge. If the quote depends on a ready base or clear access, have those conditions and the process for dealing with a problem written down.
The useful comparison is not simply which quote has the lowest total. It is which one names the greenhouse, explains the base and access assumptions, describes the fitting tasks and makes exclusions and changes clear. When supply, delivery and installation are set out in the same written scope, you can assess the full cost and decide whether the proposed arrangement suits your site—without having to guess what “installation” meant.
