Buying a Greenhouse With Installation: What Should the Quote Include?
GREENHOUSE BUYING GUIDE
Buying a greenhouse with installation can save you from arranging the product and the fitter separately, but the headline total does not show what the service actually covers. A greenhouse installation quote may combine the greenhouse, delivery and assembly, while another supplier lists the base, site preparation or unloading separately. Treat the quotation as a written scope of work as well as a price: it should identify the exact greenhouse, separate included and excluded tasks, and explain what happens if the site or job differs from the assumptions. Use these questions before comparing totals or placing an order.
Quotation checklist 1
Name the exact greenhouse on the quote
Before comparing totals, check that every quote names the same greenhouse and the precise variant you intend to order. Use the model name shown in the product information and include any identifying code, selected size, finish or configuration if the seller offers them. A label such as Classic Plus 385 helps identify the item, but its name alone does not tell you which options the price covers. Ask the supplier to state the exact version, quantity and choices that affect the specification. If a quote uses a shortened label, ask them to expand it so two similar descriptions cannot be mistaken for the same order.
Ask the supplier to attach or clearly reference the specification being priced, then compare it with the product line on the order confirmation. The record should settle practical points that matter to your choice, such as stated dimensions, glazing, door arrangement, ventilation and finish, without leaving you to infer them from a model name or photograph. If the seller changes a component or suggests a substitute, request a revised quote that identifies what has changed and whether the product price or installation scope changes too. Keep the wording consistent across the quote, product order and installation booking; that gives you one clear description to use if a detail later needs clarification.
List components and optional extras
A quote can identify a greenhouse yet leave uncertain which parts are included. Ask for a clear list of the frame, glazing or panels, doors, vents, fixings and other components supplied, using the wording in the seller’s product specification. For example, if the quote names the Aluminium Classic Greenhouse, ask which precise package and fittings that line refers to; its title does not confirm those details. Record selected shelving, staging, shade, gutters, automatic opening equipment or other accessories separately, if you choose them. An item mentioned in conversation but absent from the written list should be treated as unresolved, not silently assumed to be included.
Distinguish what is delivered from what is fitted. An accessory might be included in the delivery but not in the assembly labour, or it might be an optional extra rather than part of the greenhouse supply; the quote should state which arrangement applies. For each selected extra, ask who supplies it, who installs it, whether any necessary fittings are included, and whether fitting adds labour. Note any item you plan to buy elsewhere and ask if the fitter will install it, rather than assuming the service covers third-party parts. This avoids a gap between the components at the property and the work the installer has agreed to perform.
Quotation checklist 2
Ask for a complete, itemised total
Ask for separate amounts for the greenhouse, chosen options, delivery, assembly and any site or base work, with additional charges clearly named. If the supplier gives one package figure, request a written description of its inclusions; you need not insist on an artificial amount for every small part, but should know which services the total covers. A quote referring to the Aluminium Limited Edition Greenhouse should identify the exact product and configuration priced, not rely on a broad label. Confirm whether the quoted total includes any applicable VAT, delivery, unloading and other service charges, and whether optional items are outside that amount.
Check how the installation figure was calculated. Is it a fixed amount for the tasks described, or does it depend on a site visit, measurements or assumptions about access and preparation? Ask how travel, extra labour, a second visit, disposal and work not yet assessed would be priced, and whether you must approve a change before it is added. The quote should also show the payment schedule, any deposit or later balance, and how long the price remains valid. Compare totals on the same tax basis and for the same scope: a lower figure is not directly comparable if it excludes work another supplier has included. Avoid accepting a verbal estimate as the final amount.
Define delivery separately from installation
Delivery can mean different stopping points, so ask exactly where the greenhouse will be left and what handling is included. Does the quoted charge cover transport to the property, unloading, and movement from the drop-off point to the prepared installation area, or only some of those tasks? For an item named Bloomcabin Orangerie, make sure the delivery line refers to the same model and quantity as the product order; its name does not reveal where a carrier will leave it. Ask whether the greenhouse and any separately selected components arrive together, or whether separate deliveries and charges may apply. Have the destination written into the quote.
Give the supplier an accurate description of access and ask which details the delivery team needs: entrance width, steps, distance from the vehicle, restricted parking, or a route that cannot take large packages. Do not assume that the installer will carry items further than the delivery service. Clarify how delivery is coordinated with assembly, who checks the order against the paperwork, and whom to contact if a package is missing or damaged. Ask whether someone must be present to accept it, whether packaging is taken away, and what happens if an access problem causes a failed or repeated delivery. If an extra visit could be charged, request the amount or charging basis before accepting.

Define what assembly includes
Write down what “installation” or “assembly” means in this quote. The term might refer only to putting the greenhouse together, while anchoring, fitting a base, attaching selected accessories or preparing the ground is priced separately. With a product labelled Bloomcabin Prestige Greenhouse with Metal Foundation, ask whether the named foundation is part of the selected supply and whether fitting or fixing it is included; the title alone is not a scope of work. Ask the supplier or installer to name the tasks and materials covered, not simply the number of labour hours. That is especially important if the quote combines product and labour into one total.
Ask what condition the area should be in when the fitter arrives and what condition it will be left in. The quote can state whether the crew positions and secures the structure, fits the components on the order, checks that doors and vents operate, removes packaging and clears installation waste. Each task needs an explicit yes or no rather than an optimistic reading of “complete assembly”. Ask what remains for you to do after the installers leave, including fitting separately purchased extras or arranging work by another contractor. If the installer does not undertake a finishing task, have that exclusion recorded so you can plan it with the right person. If you expect a final walk-through, agree whether it is included and how outstanding items will be logged.
Agree the base and site-preparation work
Separate a prepared installation area from the greenhouse kit itself. Ask whether the quote includes a base or foundation, delivery of its materials, construction or fitting, and any work needed to make the chosen site ready. If the product is titled Pyramid Greenhouse for Masonry Base, use that exact reference to ask what base assumptions apply to the selected configuration and who supplies it; the title does not establish that a masonry base is included or suitable for your site. Ask the installer to state the assumptions about the surface and what will be checked before assembly. For structural suitability, obtain an assessment from a qualified professional rather than guessing from a product name.
List work that might otherwise fall outside the price: clearing an old structure, removing debris, preparing or levelling a surface, making a base, carrying out repairs, and removing surplus material or waste. These are examples to resolve, not a standard package. If another contractor is to prepare the site, write down who confirms it is ready, when that confirmation is needed and whether the greenhouse fitter will proceed if a requirement has not been met. Ask whether a delay, stop or return visit could add cost. If the base must meet specific requirements, obtain those in writing from the supplier and let the appropriate installer assess the site; do not rely on an informal description.
Quotation checklist 4
Clarify work beside a wall or existing structure
If you are considering an item titled T Model Greenhouse Orangery Wall Base, make sure the quote repeats the exact model and says what the wall or base part of the job covers. Does the price include positioning, fixing to an adjoining surface, checking the fixing point, and materials or labour for that connection? The catalogue name alone does not establish that a particular wall is suitable or that fixing is included. Ask the installer to assess the intended location and state any limitations and included tasks in writing. If the quote assumes you have already prepared a wall or base, make that assumption explicit and confirm how readiness will be judged.
Ask what happens if the existing surface needs adjustment. Drilling, removing fixtures, altering a finish, sealing a joint or repairing a wall may be excluded, require another trade, or fall outside the installer’s role; the quote should say which applies. Clarify who is responsible for getting permission from the property owner where the work affects a rented or shared space, without assuming the supplier can arrange it. If a separate contractor must complete related work, identify the handover point and sequence so the greenhouse fitting is not booked before the connection work is ready. This separates greenhouse assembly from alterations to the property.
Check the site survey, access and your preparations
Find out how the installer reached the price. Has someone visited, or is it based on measurements, photographs or details you supplied? If considering the Aluminium Lean-to Greenhouse, ask whether the proposed location and route have been checked, and whether a visit or measurement is included in the quote; the product name alone answers neither question. Ask the supplier to list assumptions about the ground, any adjoining surface, access route and available working space, then tell them about anything that may change them. A remote estimate should say what happens if an on-site check changes the scope or price.
Before ordering, confirm your part in getting the site ready: moving stored items, clearing the route, providing access on the agreed day, supplying requested measurements or photographs, and arranging separately quoted base work. Ask for these responsibilities in plain language and note when they must be completed. If the installer requires a site visit before the final price, establish who books it, whether the visit is chargeable, what it is intended to confirm and whether a revised quote follows. Do not rely on informal messages where missing preparation could lead to extra labour, a delay or an unsuccessful visit; get the requirement written into the order.
Quotation checklist 5
Compare like-for-like quotations and handle changes
Put quotations side by side by scope, not just headline price. Confirm that each covers the same greenhouse and options, delivery point, unloading, assembly, base work, fitting of accessories, waste removal and tax treatment. Mark each line as included, excluded or still to be confirmed; this makes gaps visible before you compare totals. If one quote is less detailed, ask for a revised written version instead of assuming the missing work is included. A concise quote can still be clear, but it should define its limits and identify any amount that might be added later. Compare exactly what each supplier is taking responsibility for, not just how the service is named.
Pay close attention to provisional amounts, assumptions and changes after a site survey. Ask what counts as extra work, how its cost is calculated, who explains the change and whether you must approve it before work continues. Find out what happens if the site differs from the description, a component is missing, or an agreed date has to move. Note any fee for an additional visit or delayed installation, if applicable, and ask for the supplier’s response in writing. If a new quote changes the price or scope, compare that version with your earlier record and accept only the terms you intend to order. A clear change process helps avoid disputes over unpriced tasks.
Confirm the order and completion arrangements
Before accepting, check that the quotation, product order and installation schedule use the same model, quantity and selected options. Confirm who is selling the greenhouse, who is responsible for delivery and who will carry out assembly, including the contact for queries if those roles belong to different businesses. Keep the final quote, updated specification, exclusions, price and payment terms together. Ask for the expected sequence—delivery, base preparation, installation and any separate work—without treating an estimate as a guaranteed date unless that has been expressly confirmed. If the supplier cannot confirm a date yet, ask when and how it will be agreed.
Ask how completion is recorded and whom to contact if parts are missing, damage is noticed or an agreed task remains outstanding. Check what handover information, care guidance or product documents are supplied, and whether any guarantee or after-sales support is stated separately from the installer’s labour; do not assume one automatically covers the other. If a balance is due after installation, ask what event triggers payment and how incomplete work is recorded. These are straightforward order terms, not a reason to make the quote complicated: clear names, scope, exclusions and responsibilities let you decide whether the total is worth accepting and what will happen after delivery.
Frequently asked questions
Does a greenhouse installation quote automatically include delivery?
Not automatically. Ask whether transport to the property, unloading and moving the greenhouse to its installation area are included, and whether delivery comes from the same provider as assembly. The quote should name any separate charge and confirm that it applies to the ordered model, quantity and destination.
Will the installation price include a base?
Only if the quote says so. Check separately for base materials, delivery, construction or fitting, site preparation and anchoring; an assembly charge alone does not settle these points. Have the supplier state the assumptions about the prepared surface and who confirms it is ready. For structural suitability, ask a qualified professional.
What information should I give the supplier before asking for a quote?
Give the supplier the exact product and options, the proposed location, any existing base, and honest details about access constraints. Send measurements or photographs in the format requested, and ask whether a site visit is needed before a firm price can be given. Keep those assumptions with the quote.
Can I compare two quotes by their total prices?
Match the model and options, quantity, delivery and unloading, assembly tasks, base work, extras, tax treatment, exclusions and extra-work terms. Mark anything still unconfirmed. If one supplier gives only a single total, ask for a written scope before treating the quotes as comparable.
What if the installer finds extra site work is needed?
Ask how a difference found on site will be recorded and priced, and whether work pauses until you approve a revised scope. The quote should state any charge for a return visit or delay, where applicable. Keep each approved change in writing with the original quote.
An installation quote is useful to compare when it identifies the greenhouse you will receive and sets clear boundaries around delivery, assembly, site preparation and optional work. Read the inclusions beside the exclusions, check the assumptions about access and the base, and ask how extra work is authorised. If two prices appear far apart, resolve the differences in scope before choosing. The most useful quote is not necessarily the longest; it is the one that lets you understand the total, your responsibilities and what the installer has agreed to complete.
