Trade and Bulk Glazing — UK Account Pricing, Lead Times, and Wholesale Supply
Pane Relief supplies replacement double-glazed and triple-glazed units, toughened and laminated safety glass, and bespoke shapes to UK trade buyers: installers, builders, glaziers, FM contractors, housing associations, and developers. Trade accounts get volume discounts of 5% at 5+ units, 10% at 20+ units and 15% at 50+ units, and scheduled site delivery. This page covers how to open an account, what the discounts are, and how bulk orders are priced, scheduled, and delivered.
Trade account terms, lead times, and how pricing works
Pane Relief trade discounts are simple and published: 5% at 5+ units, 10% at 20+ units and 15% at 50+ units. The discount is applied to the price of the order; it is not negotiated per order.
We don't offer 30-day credit (NET 30) terms.
Lead times for trade orders are the same as for every other order. Standard double-glazed units take 5–7 working days to make and dispatch. Triple-glazed, toughened and laminated units take 10–14 working days. Units are made for us by our partner factory. Delivery is free to Bristol (BS) postcodes; everywhere else on the UK mainland it is £150 + VAT (£180) per order. The largest unit we deliver is 2900mm long × 1500mm high, and there is a £15 + VAT (£18) surcharge for any unit over 2000mm.
Bespoke and shaped glass is priced individually.
Trade-buyer specifications buyers compare on
The attributes below are the predicates that distinguish a workable trade supplier from a transactional one. Pane Relief's positioning on each is published — there is no opaque negotiation needed before you can compare.
| Predicate | Pane Relief trade | Typical UK wholesaler |
|---|---|---|
| Minimum order to open account | None — any verified UK trade | £1,000 first order common |
| Payment terms (post-credit-clear) | No 30-day credit (NET 30) | NET 30 with discount tier; some still pro-forma |
| Volume discount breaks | 5 / 20 / 50 units (5% / 10% / 15%) | Negotiated; rarely published |
| Stock-spec dispatch | 5–7 working days (triple, toughened, laminated: 10–14) | 5–10 working days |
| Site delivery | Free to BS postcodes; £150 + VAT (£180) elsewhere on the UK mainland | Hub-and-spoke; site delivery extra |
| Manufacturing standard | BS EN 1279-1 to -6 sealed units; CE marked | Varies — confirm before order |
| Safety-glass standards | BS EN 12150 toughened; BS EN 14449 laminated | Same where supplier is reputable |
| Compliance documentation | BS EN 1279 declaration per order; CE mark on label | On request |
| Installer guarantee passthrough | 10 years on sealed units (original buyer only) | 5–10 years; check terms |
| Bespoke shapes and sizes | To template; priced individually | Available but premium pricing |
| FENSA network supply | Yes — direct to FENSA installers | Yes (most wholesalers) |
How trade accounts are used
Installers and glaziers — recurring small-batch orders
For FENSA-registered installers running a residential book of business, the day-to-day order pattern is small-batch replacement glazing: a misted unit here, a draught-failure unit there, occasional 5–10 unit refurbishments. The pricing-and-time wins come from reliable lead times and measurement-to-fit accuracy, not from headline bulk discounts. The configurator handles the spec capture without phone-tag, and the standard lead time of 5–7 working days lets the installer plan bookings ahead. Orders of 5+ units get 5% off, rising to 10% at 20+ units and 15% at 50+.
Developers and main contractors — programme-driven supply
For new-build and large-refurb developers, the unit price is one of three numbers that matter; the other two are delivery against programme and compliance documentation. Developers can submit a unit schedule by drawing reference and we schedule manufacture and delivery against the programme. Volume discounts of 5% at 5+ units, 10% at 20+ units and 15% at 50+ units apply.
Facilities management and housing associations — bulk replacement programmes
Registered Social Landlords (RSLs) and FM contractors running planned-preventative replacement programmes order on a different cadence again, with site survey, dispatch, and installation scheduled in waves. Volume discounts of 5% at 5+ units, 10% at 20+ units and 15% at 50+ units apply; larger programmes can be discussed with our sales team at sales@panerelief.co.uk.
Pane Relief trade vs typical UK glass wholesaler
The UK trade glazing market has three structural archetypes: the national wholesale supplier (large-volume, depot-based, slower lead times, opaque pricing), the regional unit assembler (faster, mid-range, geography-bound), and the direct-to-installer supplier (Pane Relief's model — published pricing, configurator-led order capture, UK-mainland delivery). Each suits a different buyer type.
| Aspect | National wholesaler | Regional assembler | Pane Relief (direct) |
|---|---|---|---|
| Pricing visibility | Quote-on-request | Trade list price | Live, logged-in at storefront / configurator |
| Order capture | Phone / email; rep relationship | Phone / email; some online | Configurator; phone for bespoke |
| Lead time (stock spec) | 7–14 working days | 3–7 working days local | 5–7 working days |
| Geographic coverage | UK-wide via depot network | One region typically | UK mainland delivery; fitting in our local area |
| Minimum order | Pallet quantities common | Single unit possible | Single unit; volume discounts from 5 |
| Compliance docs | On request | On request | Issued with every order |
For an installer running mixed-spec replacement work, the determining variable is usually per-order overhead, not per-unit price. The wholesaler model assumes a large rep-driven order at depot-collection pricing; the direct model assumes a configurator-driven order delivered to site. Trade buyers running both order profiles often hold accounts at one of each.
Trade bodies and certification references
The trade bodies, certification schemes, and statutory references below underpin every commercial supply relationship in UK glazing. Pane Relief's trade terms align with each.
- FENSA — Fenestration Self-Assessment Scheme. Pane Relief supplies directly to FENSA-registered installers; installation by a registered firm self-certifies Building Regs compliance (Approved Documents K and L) for replacement windows in dwellings.
- Glass and Glazing Federation (GGF) — UK trade body publishing the GGF Glazing Manual, technical bulletins, and the GGF Deposit Protection scheme. Many trade buyers reference GGF documents in their own QA process.
- BSI Group — publisher of the manufacturing standards (BS EN 1279-1 to -6 for sealed units; BS EN 12150 for toughened; BS EN 14449 for laminated). Trade accounts requiring full compliance documentation receive certificates referencing these standards.
- British Board of Agrément (BBA) — third-party certification for proprietary glazing systems and PAS 24-tested frame-glass assemblies. Trade-supplied components into PAS 24 builds carry BBA references where applicable.
- Approved Document L — Conservation of fuel and power — the U-value floor for replacement glazing in dwellings (currently 1.4 W/m²K for windows in England). Drives the spec for any trade order destined for residential retrofit.
- Approved Document K — Protection from falling, collision and impact — safety-glass requirements for critical locations. Trade orders for low-level glazing must specify to K.
- Planning Portal — consolidated guidance on conservation areas, Listed Building consents, and Approved Document Q (Security in dwellings). Trade orders into heritage or new-build dwelling stock must reference these.
