The lowest pane price does not always produce the lowest complete order cost. Delivery, quantities and the exact material being supplied can change the comparison considerably. Ask every supplier to quote against the same pane list, then compare the total you would pay for the job you actually need.
Keep the quotation date and reference beside each offer. This is particularly helpful when you have one email quote, one online basket and an option to collect locally.
Make sure the orders match
Begin with the specification. Does each offer cover the same material, thickness, shape, dimensions and quantity? If a supplier proposes an alternative, ask for that change to be described clearly.
For example, an offer for four rectangular acrylic panels cannot be directly compared with an offer for three glass panels and an unspecified shaped piece. Mark the difference and obtain the missing detail before ranking the totals.
Add the charges you can confirm
Record the panes, any separately priced cutting or shaping, required accessories, packaging, delivery and VAT treatment. For an offer excluding VAT, ask the supplier for the final amount payable including VAT, where applicable. Enter delivery for your actual postcode.
Delivery arrangements vary. Halls says its accessory and spare-part charges depend on the item, with the final cost shown at checkout. The Greenhouse People highlights the cost of shipping replacement glass and suggests considering local supply or collection. Halls delivery information, Replacement glass delivery advice
Keep collection as a separate choice
If collection is available, record the location and the supplier’s arrangements. Add a travel estimate only if it helps your decision, and label it as your estimate. Also consider whether you have a suitable way to transport the order or need to arrange help.
An illustrative comparison makes the point: an £84 pane order with £24 delivery totals £108; a £96 pane order with £8 delivery totals £104. These invented figures demonstrate the arithmetic and are not current supplier prices.
Check what happens next
Ask about availability, expected lead time and the delivery method. Read the supplier’s instructions for reporting transit damage and the conditions applying to custom-sized orders. Record any answer that affects whether the order works for you.
Keep unknown amounts visible. ‘Delivery to be confirmed’ is a missing cost, rather than a zero charge. A quote with that entry should stay incomplete until the supplier responds.
Choose from offers that meet the same confirmed requirement. Then you can weigh the complete cost alongside timing, collection arrangements and the clarity of the supplier’s answer, with the important details in front of you.
