Switching washroom supplier in the UK takes 2–4 weeks with no service disruption. Audit your current product list and quantities, check dispenser compatibility with your new supplier's products, then time your first delivery to arrive while you still have 1–2 weeks of existing stock. No contract, no minimum order — a single case is a valid first order.
Most businesses don't leave bad suppliers because of the cost. They stay because switching feels complicated. That's a reasonable instinct — and an expensive one.
Why Businesses Stay With Bad Suppliers (And Why Inertia Is Expensive)
It's rarely about loyalty. It's about time. The procurement manager already has seventeen other things to sort. The FM team doesn't want to deal with dispenser questions. And honestly, the current supplier is fine — not great, but fine.
That's the trap. "Fine" has a cost you don't see on an invoice.
Prices creep up by 3–5% annually with no conversation. Quality drifts — thinner rolls, inconsistent deliveries, packs that don't match what you ordered. The complaints from the team stop going anywhere. And because no single incident is bad enough to trigger action, the whole situation just... continues.
We're not here to shame anyone for staying put. Switching suppliers is work, and work takes time. But the process is genuinely simpler than most people expect — and this guide shows you exactly how to do it without a single stock gap.
What to Audit Before You Switch: Products, Quantities, and Spend
Before you contact any new supplier, spend 20–30 minutes on a basic audit. This one step prevents every common switching mistake.
Four things to capture:
- List every product you currently order. Toilet rolls, paper hand towels, centrefeed rolls, soap, dispensers, bins — everything. Pull from the last 3 invoices if memory fails you.
- Note monthly quantities and current prices. Per case, per unit. This becomes your comparison baseline.
- Check your dispenser brands and models. Look for the model number — usually on a sticker inside the housing. This matters more than most people realise.
- Identify your actual pain points. Late deliveries? Inconsistent quality? Poor communication? Write it down. A good new supplier will want to know.
Below is a worked example for a typical UK office of 50–80 staff. Use the numbers as a reference, then replace them with your own figures from the last three invoices:
| Product | Monthly Qty | Current Price (per case) | Dispenser Model | Pain Point |
|---|---|---|---|---|
| Jumbo toilet rolls | 4 cases | £18.50 | Tork T1 | Inconsistent core size |
| Paper hand towels (interfold) | 6 cases | £24.00 | Tork H2 | Sheets tear in dispenser |
| Centrefeed rolls | 2 cases | £32.00 | Brightwell BC2 | Core too small — slips |
| Foam soap refills | 3 cases | £42.00 | Brightwell ModularDuo | Runs dry mid-week |
| Sanitiser gel | 2 cases | £38.00 | Free-standing stand | Dries hands out |
| Bin liners (heavy duty) | 4 cases | £15.00 | N/A | Splits on lift-out |
| Total monthly spend | ~£170 + VAT (excluding ad-hoc dispenser repairs) | |||
Print this table or copy it into a spreadsheet. Once you have the real numbers from your last three invoices, send the completed list to your prospective new supplier — they should come back with a like-for-like quote within two working days.
The Step-by-Step Transition Plan That Avoids Stock Gaps
The number one fear about switching is running out of something mid-month. Done properly, that doesn't happen. The principle is simple: overlap, don't swap overnight.
- Contact your new supplier with the audit list. Send them everything from your checklist. Ask them to confirm they can match or recommend alternatives for each product. A good supplier will respond with specific recommendations — not a generic catalogue link.
- Confirm dispenser compatibility before placing any order. This takes one conversation. Don't skip it. Ordering products that don't fit your dispensers creates a whole new problem.
- Time your first delivery carefully. Aim to receive your first order while you still have 1–2 weeks of current stock remaining. You want buffer. You do not want to be waiting on a delivery with empty dispensers.
- Run both suppliers in parallel for two weeks. Yes, briefly. This lets you test the new products in real conditions — actual usage, actual feedback from your team, actual delivery experience. It costs slightly more for a fortnight. It's worth it.
- Cancel the old supplier after confirming the new one works. Not before. Give the new supplier one full delivery cycle to prove themselves. Check your contract terms — most have a short notice period or none at all.
The whole transition typically takes 2–4 weeks from first contact to full switch. Most of that time is just waiting for deliveries.
The rule: Never cancel the old supplier first. Always let the new relationship prove itself before you close the door.
Dispenser Compatibility: The Practical Question Most People Miss
This is where switches go wrong most often — not because it's complicated, but because nobody thinks to check until there's a problem.
Most dispensers are designed to accept products from multiple suppliers. Standard sizes — single-sheet hand towels, 2-ply jumbo rolls, centrefeed cores — are broadly compatible across brands. If your dispensers are from Tork, Kimberly-Clark, SCA, or similar manufacturers, there's a good chance another supplier's products will fit without any changes.
However, some dispensers are proprietary. The manufacturer has intentionally designed them to only accept their own refills. Certain soap systems and some paper roll dispensers fall into this category. If you're locked into a proprietary system and the new supplier doesn't offer compatible products, you'll need to replace the dispensers.
How to check in three steps:
- Find the model number on your dispenser (usually inside the door or on the back panel).
- Note the brand — Tork, Essity, Brightwell, Vectair, etc.
- Ask your prospective new supplier directly: "Do your products work with this model?"
At Tisha, we check compatibility before your first order. If your current dispensers work with our products, there's nothing to replace. If they don't — we'll tell you that clearly, and we can supply alternative dispensers as part of the setup. No surprises.
What to Expect in the First 90 Days
Weeks 1–2: Overlap period. You're testing the new products alongside existing stock. Pay attention to quality — sheet strength, absorbency, how the rolls fit the dispensers. Ask your facilities team for honest feedback. This is when issues surface, before you're committed.
Weeks 3–4: Full transition. New supplier is your primary source. Old supplier has been cancelled or is winding down. Your team is using the new products exclusively. Any teething issues should be raised immediately — not filed away for later.
Month 2: First full review. You have a complete month of data. Check: Did deliveries arrive on time? Did the products match the spec? Is the pricing what you agreed? Compare your cost per visit against the previous supplier.
Month 3: Settled routine. Standing order is in place. You know the lead times. Your team has stopped noticing the change — which is exactly what you want. Washroom supplies should be something that just works.
If anything isn't right in that 90-day window, a good supplier fixes it immediately. Not after three emails. Not after you escalate. The first 90 days is when a supplier shows you what they're actually like.
One case. No contract. No minimum. That's how we think switching should work — low stakes, so you can see for yourself whether Tisha is right for your washrooms before you commit to anything.
