A bill of quantities (BOQ) is the single most important document you send a supplier. A clear BOQ reduces clarification requests and helps suppliers confirm accurate pricing. Final quotation timing depends on the scope and supplier confirmation. Here is how to get it right.
1. One line, one item
Each line should describe exactly one product: description, brand (or 'approved equivalent'), specification reference, unit and quantity. Avoid bundled lines like 'wiring accessories — lot'. A lot price hides cost and makes comparison between suppliers impossible.
2. Write specifications, not just names
'Twin socket' can mean a dozen different products. '13A twin switched socket outlet, white moulded plate, BS 1363, MK Logic Plus or approved equivalent' can be priced instantly. Include ratings, sizes, colours, mounting type and the standard the item must meet.
3. Use real units and check your sums
Cable in metres, conduit in lengths, devices in numbers. Mixed or missing units are the most common reason estimators stop and ask. Double-check that quantities match your drawings — over-ordering ties up cash, while shortages stall site work.
4. Flag long-lead and critical items
Mark items with long manufacturer lead times, such as panel boards or special light fittings, so your supplier can quote realistic delivery dates and suggest in-stock alternatives where the programme is tight.
5. Send an editable file
A scanned PDF must be retyped before it can be priced — that alone can add a day. Use an XLS or XLSX workbook where possible, with one sheet per package. The BOQ form also accepts PDF and JPEG; contact the team if you need to send another format.
Follow these five rules and you make it easy for any supplier to give you their best price quickly. Submit your BOQ using the website form. We aim to respond by email within one business day; final quotation timing depends on your requirements and supplier confirmation. Keep the returned project reference for follow-up.
