A pergola quotation checklist that makes offers comparable
TTH Pergola pergola design guide: prepare dimensions, roof controls, accessories and delivery details before comparing aluminium pergola quotations.
A useful quotation describes the same finished result
Two quotations can display the same roof dimensions and still cover quite different work. One may include side screens, controls and a particular finish, while another lists the frame and roof only. Even a small difference in what is supplied can change the installation sequence or leave an interface unresolved. Before comparing totals, write down what the completed outdoor space should contain and ask each supplier to respond against that same list.
For a TTH Pergola enquiry, separate the specification into the structure, operating equipment, optional sides and delivery scope. Identify who supplies anchors, electrical connections and any site preparation rather than assuming they are included. The product information on tthpergola.com is a starting point for this conversation, not a substitute for the final order schedule. A simple comparison table can have three columns: your requirement, the quoted inclusion and the item still needing confirmation. This approach makes a lower price easier to interpret without assuming it represents either better value or lower quality. The most useful question is what changes in the finished result, the responsibilities or the support when one line of the quotation changes.
Compare a complete configuration, not a headline price
Two pergola quotations are only comparable when they cover the same size, model, finish, accessories and delivery scope. A low headline figure may refer to a basic frame, while another offer includes screens, lighting or additional installation items. Build one written specification and send the same version to each supplier. This makes differences easier to identify and reduces the risk of discovering missing components after the order is placed.
Use a short specification table
Record dimensions in one unit and define whether they refer to the overall roof, post centres or clear space. Attach a sketch whenever a term could be interpreted in more than one way. The supplier should mark any unconfirmed item instead of quietly choosing a default. Keep optional items on separate lines so they can be added or removed without obscuring the base configuration.
| Item | Information to confirm |
|---|---|
| Size and model | Overall dimensions, clear height, family and exact model |
| Roof and controls | Operation type, controls and included electrical components |
| Side accessories | Number of openings, dimensions, screen or glass arrangement |
| Delivery scope | Packing, transport terms, installation items and exclusions |
Separate product questions from site questions
A product quotation cannot resolve unknown ground conditions, concealed services or an unverified wall. Describe the intended supporting surface and provide photographs, but identify anything that requires a site assessment. Ask who is responsible for measurements, foundations, electrical work and installation. These responsibilities should be clear before comparing the final total. Changes to the site or the approved layout can change the scope even when the visible pergola looks similar.
Finish with a traceable order record
Before approval, match the quotation to the latest drawing and configuration list. Confirm the finish reference, quantities, packaging requirements and the process for reporting damaged or missing items. Save the agreed documents together so later questions can be answered against the same specification. A useful quote is a practical description of what will arrive and what remains to be arranged locally, rather than a list of attractive features without defined boundaries.
- Ask for a separate price for each optional accessory.
- Record drawing versions and the exact model in the order.
- Confirm exclusions and any outstanding checks before approval.
Should I compare only the price per square metre?
Area pricing can help organise an initial enquiry, but it hides differences in profiles, accessories, transport and installation scope. Ask for an itemised TTH specification and compare equivalent configurations before judging the total.
