How to Plan a Multi-Drop Delivery Route That Actually Saves Fuel

A 40-drop day in a 7.5-tonner is not the same job as a 40-drop day in a Transit. The tail lift, the weight you're carrying between stops, the access, the time windows — all of it changes how the day should be sequenced. What doesn't change is that a badly ordered run costs you fuel at every junction, every three-point turn and every minute spent idling while you dig for the right pallet.

The good news is that most of the saving happens the night before, at a desk, with a pen. Here's how to do it properly.

Map the constraints before you map the route

Start with everything you cannot change. Booked slots, delivery windows, vehicle access restrictions, low bridges, weight limits, school streets, market-day closures, sites that won't take anything before 8am because there's nowhere to turn. Write them down on one sheet before you open the map.

Then split your drops into three buckets:

• Fixed — locked to a time window or a booked slot, and not moving.
• Semi-flexible — a window exists but a phone call could widen it.
• Free — any time that day.

Most planning failures come from treating the middle group as if it were the first.

Fixed drops anchor the day

You don't sequence a route and then try to squeeze the windows in. You place the anchors first, then build the run around them. A 7am crane booking and a 4pm school are the two ends of your day, whether you like it or not.

Sequence in three passes

1. Cluster geographically. Ignore time windows entirely. Group drops that sit within a few minutes of each other, even if they're currently planned at different times of day.
2. Order within each cluster so you don't cross your own path. Work from the far edge back towards base, or towards the next cluster, rather than zig-zagging in and out.
3. Weave the windows in by moving whole clusters, not individual drops. Shifting one stop to fix a window usually breaks two others.

The mental picture that helps: imagine a spine road running down the middle of your patch. Work one side on the way out, the other side on the way back. It sounds obvious, but a surprising number of runs still deliver past a door on the way out and then come back past the same door two hours later.

Which side of the road matters more than people think

A drop on your left is a simple pull-in. A drop on the right means crossing traffic, or a loop around a block, or a manoeuvre that costs you five minutes. Where you can, sequence so consecutive drops land on the same side of the street. On a road with premises on both sides, do one side outbound and the other on the return.

Load in reverse, label by stop number

The load bay is a route in itself. Every minute spent hunting for a pallet is a minute on the clock, and re-stacking a bay costs both time and fuel.

• Last drop goes on first. The reverse of the running order is the loading order.
• Number every pallet, cage or tote with the stop number in large marker. Not the address — the number.
• Keep heavy items low and forward, but never bury the first three drops behind a tonne of anything.
• Segregate by customer, not by product type. Mixed loads sorted by SKU are a nightmare at the tail lift.
• Keep the tail lift platform and the ramp path clear. That space is not storage.
• On mixed runs, treat it as two load zones: the back half for the first five drops, the front half for the last five.

Load security and axle weights sit under operator licence rules, and they're not a matter of judgement. If you're unsure whether a particular load is legal on a particular vehicle, check with your transport manager or the relevant authority rather than guessing.

Time windows: widen, stack, buffer

Ask. Most customers will happily move a two-hour window to a four-hour one if you explain that it means a more predictable arrival and a driver who isn't sprinting. The ones who genuinely can't, keep as fixed anchors and plan around them.

Where several drops in the same postcode share a similar window, treat them as a block. The short hops between them are cheap; the second trip across town is not.

Then build slack in. A plan with no buffer fails at the second drop and you spend the rest of the day chasing twenty minutes — which means harder acceleration, more idling at gates and worse decisions. A ten to fifteen per cent time allowance is not wasted time. It's how the route stays efficient after it meets reality.

Early deliveries and keyholder arrangements

Some sites will take a pre-7am drop via security or a keyholder. That gets you out before the traffic builds and off the road before the afternoon peak. Get any such arrangement confirmed in writing with the customer, and check that access, lighting and safe working conditions are genuinely in place at that hour — a shortcut that puts someone at risk is not a shortcut.

Fuel waste that route software won't fix

• Idling at drops. If you're stationary for more than a minute or so, switch off — unless you need the engine for the tail lift, the fridge or a PTO.
• Tyre pressures. Under-inflated tyres burn fuel, and you won't feel it from the cab. Check them on a schedule, not when something looks flat.
• Empty roof racks and bars. Drag you're carrying for nothing, every mile of the day.
• Dead weight. Empty cages, spare pallets, returns you could have cleared yesterday.
• Racing between drops. Hard acceleration followed by hard braking is the single most wasteful way to cover a short urban leg.
• Defaulting to the motorway. The shortest distance on paper is often not the cheapest journey, especially when it means a long detour to a junction.
• Over-optimising. Planning software will confidently hand you a route that is technically shorter. It has never queued for two hours at the gate of a distribution centre. Your driver has.

Brief the driver, then listen to them

A route only saves fuel if it's actually followed, and it's only followed if it works on the ground. Give the driver a clear run sheet: sequence, window, access notes, contact number, and a fallback — which drop to sacrifice first if the day starts slipping.

Then ask what changed. Five minutes of end-of-shift feedback is worth more than another hour of planning. If three drivers independently skip the same drop order every week, the plan is wrong, not the drivers.

The five-minute habit that pays for itself

Before the shift, glance at the run sheet and check three things: are the fixed drops anchoring the day, are the clusters tight, is the load numbered in reverse. After the shift, note the two things that cost you the most time.

Do that consistently for a fortnight and the fuel saving arrives without anyone having to chase it. No dramatic overhaul, no new technology required. Just a tighter sequence, a smarter load and a bit of honest slack in the day — which is what efficient multi-drop work has always looked like.
