At Independent Slate Supplies, our strength as a leading slate supplier lies in the people behind the business. With decades of combined experience in the slate industry, our dedicated team works closely with trusted and established partners to ensure we remain a reliable slate supplier of the highest-quality natural slate to customers across the UK.

Introducing the Depot Rewards Scheme

We know purchasing decisions at depot level involve real trade-offs. That’s why Independent Slate Supplies has created a reward scheme built specifically for the people who make those calls every day – your team.

This isn’t about changing how you work. It’s about giving your depot tangible recognition for buying from a supplier your head office already trusts. One that’s been vetted for quality, warranty, financial stability, and long-term reliability.

What the scheme delivers

The Depot Reward Scheme offers a direct, transparent incentive that works for your depot and your business. Rewarding purchasing decisions your head office already supports.

• Rewards for your team – Tangible vouchers earned on every qualifying ISS order, spendable at depot level.
• Approved supplier confidence – Trade through a supplier your head office has already vetted for quality, warranty and reliability.
• Visible, traceable value – Every voucher earned is recorded — giving depot teams clear sight of what their purchasing generates.
• Stronger rebate contributions – Participating depots help maximise rebate performance across the wider business.
• Trade agreement participation – A simple way to support and activate the agreements already negotiated on your behalf.
• Stronger supplier partnerships – Consistent ordering builds the relationships that deliver better service, availability and terms.

How it works:

Depots earn reward vouchers when purchasing qualifying products from a pre-agreed ISS product list. Vouchers are redeemable and spendable at depot level, providing immediate, tangible benefits for your team, with no extra admin involved.

Rewards are allocated once a completed Proof of Delivery (POD) has been returned to rewards@independentslatesupplies.com. Depot teams should ensure PODs are being sent back promptly for vouchers to be issued without delay.

Once delivery is confirmed, the voucher is sent directly to the nominated depot account email address. Earned and pending points can be tracked at any time via the depot’s customer login at independentslatesupplies.com/dashboard.

Depots can use their rewards flexibly, for example:

• Team lunches or social events
• Staff recognition or milestone celebrations
• Annual gatherings such as Christmas parties

As a trusted slate supplier, we’re specialists in the import and distribution of high quality, competitively priced natural sills, flooring and roofing slate. With over 30 years experience of sourcing and importing you can be confident that our range of slate offers outstanding quality at competitive prices, to cover all requirements.

During the 1950s and 1960s Len Phipps grew a successful roofing contracting business serving the south west. In the 1980s, faced with the challenge of erratic supply of indigenous slate, his son Peter discovered new sources in Spain and Brazil. Good contacts, reliability and regular supplies lead a growing number of local roofing merchants to rely on Peter for their natural slates.

ISS offers a beautiful and consistent range of natural slate, ideally suited to any, and all construction projects. Slate is a superbly durable product that is unaffected by normal extremes of temperature and is highly resistant to acids, alkalis and other chemicals. It retains its colour, even in UV light and is impermeable to water, in addition slate is non-combustible and is compatible with all other building materials making it look fantastic in situ. These characteristics make it ideal as a building material, and more specifically as a covering for roofs and walls, sills and flooring.
