An empty lorry costs almost exactly what a loaded one costs. Same driver wages, same tyres, same insurance, same finance payment on the unit, near enough the same fuel burn. The only difference is that one of them is earning.
Department for Transport road freight statistics put empty running at roughly 30% of HGV kilometres travelled in Great Britain. That figure has barely shifted in a decade. Meanwhile the loads that would fill those legs are posted on freight exchanges every hour of the working day, priced, dated, and waiting for someone to ring.
So the information is not the problem. The habit is.
The margin hiding in the return leg
Treat the return leg as its own job and the economics look ordinary. Treat it as an addition to a journey the vehicle was making regardless, and it changes shape entirely.
Take a trunk from Manchester to a customer near London. The outbound rate covers the round trip, because that is how the job was quoted. The vehicle is coming home whether it carries anything or not. The wages are committed. The fuel is mostly committed. The extra cost of putting freight on the trailer for that return is loading time, a small amount of additional diesel for the weight, and the admin.
Which means a £280 return load is not £280 of revenue. It is close to £280 of contribution, landing on a cost base you have already paid for.
Run that across a fleet of twelve vehicles, three times a week, and it stops being loose change. It becomes the difference between a business that survives a bad quarter and one that does not.
Why hauliers skip them anyway
The reasons are practical, and most of them are fair.
Planners are measured on the outbound job. Getting the delivery there on time is the contract. Finding freight for the way home is extra work, competing with a phone that rings all day.
The search itself eats hours. Refreshing exchanges, calling shippers who have already filled the load, negotiating a rate, checking whether the collection window survives the driver’s remaining hours. By the time all that is done, the vehicle is often halfway home.
Then there is timing risk. A two hour wait at a distribution centre can wipe out the return window entirely, and a driver stuck outside a gate at hour nine is a bigger problem than an empty trailer.
Payment risk sits underneath everything. Unfamiliar shippers, no credit history, thirty day terms that quietly become sixty. Some operators have been burned once and never went back.
The backloads UK operators leave on the table
None of those objections argue against return freight. They argue against doing it manually, in a hurry, at four in the afternoon.
The backloads UK exchanges carry are not evenly distributed. Certain corridors have dependable two way volume. Others are structurally imbalanced, which is exactly why rates out of them are soft and rates into them are strong. Operators who know which is which price their outbound work accordingly and stop guessing.
That is a planning decision, not a scramble. The haulier who quotes a Midlands to Kent job already knowing what typically moves back on that lane is quoting from a different position than the one hoping something turns up.
Where a transport management service earns its keep
Most small and mid sized fleets cannot justify a full time person doing nothing but sourcing return freight. That is the gap a transport management service fills.
The useful ones do the searching, the credit checking, the rate negotiation, and the paperwork, then hand the planner a load that is already vetted. They see backloads UK wide rather than one operator’s usual patch, which matters when your vehicle is somewhere it does not normally go. They also carry the payment risk in many cases, invoicing you or paying you on agreed terms instead of leaving you chasing a shipper you have never met.
Before signing with anyone, ask how they are paid. A provider taking a margin on every load has an incentive to fill vehicles. One charging a flat monthly fee has an incentive to keep you subscribed. Neither model is wrong, but they behave differently when a marginal load comes up at a marginal rate, and you should know which pressure you are buying.
Ask about payment terms on your side too, along with what happens when a load cancels at the gate.
Rate erosion is the real objection
The argument you hear most often is that cheap return freight drags the whole market down.
There is something in it. Backload rates sit below primary rates because everyone knows the vehicle is going that way regardless, and a market where every truck undercuts every other truck on the way home is not healthy for anyone.
The practical answer is a floor. Work out what a return leg has to earn before it is worth the loading time, the driver hours, and the wear, then refuse anything underneath it. An empty run home on a bad rate day is not a failure. Hauling for £90 and losing the driver two hours of available duty time usually is.
What to measure
Empty running percentage per vehicle, tracked weekly. Most operators guess this number and guess low.
Revenue per total kilometre alongside revenue per laden kilometre. The gap between the two is the size of the opportunity.
Backload conversion rate, meaning how many return legs actually carried freight against how many could have. If nobody owns that number, nobody improves it.
Start with one lane
Pick the corridor your vehicles run most often. Check what freight moves in the opposite direction, at what rates, on what days. Set your minimum acceptable return rate for that lane and write it down.
Run it for a month, measure the difference in revenue per kilometre, then repeat on the next lane. Fleets that build backloads UK planning into how they quote work, rather than treating it as a salvage job at the end of the day, tend to find the money was there the whole time.
