Backloads are paid loads a haulier carries on the return leg of a journey, so the truck doesn't drive home empty. UK hauliers find them on load boards, through direct shipper contacts, forwarders and port networks. Even a modest backload rate usually beats running empty, which costs real fuel and wages.
This guide is for hauliers, owner-drivers and transport planners who want fewer empty miles and better margins. It covers the definition, the true cost of running empty, the eight best places to find return loads, how load boards compare with brokers, and how to price a backload so it actually pays. If you just want the work, browse live loads now and come back to the detail later.
What is a backload?
A backload (also called a return load) is freight a haulier picks up near where they’ve just delivered and carries back towards base or towards their next job. The outbound job pays for the trip; the backload turns the return leg from a cost into income.
Here’s how it works in practice. A Felixstowe-based container haulier delivers an import box to a warehouse in Daventry on Tuesday morning. Without a backload, the truck runs 130 miles back to the port empty. With one, the planner finds an empty container that needs returning to Felixstowe, or a curtainsider part load from a Northampton DC heading east, and the trip home pays. Backloads don’t have to finish at your yard. A “triangle” that takes you from Daventry to Bristol and then a third load back east can beat a straight return.
| Term | What it means | When you'd use it |
|---|---|---|
| Backload / return load | A paid load on the leg home | Every time a truck would otherwise run back empty |
| Part load | Sharing a truck with other freight | When the return job doesn't fill the trailer |
| Groupage | Several consignments consolidated on one vehicle | Pallets for multiple customers on one lane |
| Triangulation | Chaining three or more legs instead of a straight return | When the best backload isn't on your direct route home |
| Empty running | Driving with no load at all | What backloads are meant to reduce |
Backloads usually pay less than outbound work, because the shipper knows the truck is coming back anyway. That’s fine: the comparison isn’t with a full outbound rate, it’s with earning nothing. Our step-by-step guide, how to find backloads, covers the tactics in more detail.
Who posts backloads?
Most backload work isn’t labelled “backload” at all. It’s ordinary freight posted by shippers, forwarders and brokers who need a truck on a certain day. What makes it a backload is that it happens to suit the haulier’s return route. Some shippers deliberately post flexible loads because they know returning trucks will quote keenly. Forwarders post empty container returns and export collections, which fit naturally after an import delivery.
The cost of empty running
The Department for Transport’s road freight statistics show that 30% of the distance driven by GB-registered HGVs in 2024 was empty, 5,843 million kilometres out of 19,394 million. The share was the same in 2023. Not all of that is avoidable: tippers, tankers and specialist vehicles often can’t carry anything back. But for curtainsiders, box vans, flatbeds and container skeletals, a large part of it is lost income.
What does an empty mile cost? Fuel is the biggest part. In late September 2026 the RAC put the UK average diesel price at 199.18p a litre. A VAT-registered haulier pays about 166p net. A loaded 44-tonne artic typically returns around 8–9 mpg, a bit better when empty. At 8.5 mpg, fuel alone costs about £0.89 per mile. Add driver time, tyres, maintenance and depreciation and the true figure is well over £1.50 a mile for most operators.
Worked UK example
Manchester to Felixstowe is about 210 miles. Run empty at 8.5 mpg, that is 24.7 gallons (112 litres) of diesel: roughly £186 at 166p net. Add about 4.2 hours of driver time (at an average 50 mph) at £18 an hour, roughly £76, and the empty return costs about £262 before wear. A backload paying £450 doesn't just cover that; it adds nearly £190 to the day.
The factors that change your cost per empty mile are fuel price, the vehicle’s mpg, driver pay, distance, and how long the truck waits before it can move. Plug in your own numbers below:

Where to find backloads
There’s no single source. Successful operators use several and check them at set times. In rough order of how quickly they pay off:
- Load boards. Filter by the area you’re tipping in, not where you’re based. Check the evening before and again at 7am. Freight1 live loads.
- Post your truck. List the empty leg with time, trailer and where you can go. Shippers search for trucks too. Post a truck.
- Ask the customer you’re delivering to. Warehouses often have returns, empties or outbound pallets with no transport booked. Ask the goods-in team, not just the driver office.
- Freight forwarders. Forwarders juggle container returns and urgent moves daily. Get on two or three local forwarders’ subcontractor lists near the ports you serve.
- Port networks. Empty container returns and export loads are constant at Felixstowe, Southampton and London Gateway. Know which shipping lines use which depots.
- Regular lanes. If you run Felixstowe to the West Midlands three times a week, find one shipper in the Midlands with eastbound freight and offer a standing rate.
- Pallet networks. Membership of a pallet network gives trunking work, but it comes with obligations. Weigh that against your current flow.
- Other hauliers. Swapping work with a firm based where you tip is one of the oldest backload tricks. A good relationship is worth more than one job.
Your daily backload routine
- Check tomorrow's tipping points the night before
- Post every empty leg as an available truck
- Message within minutes, not hours, with truck type and ETA
- Note which shippers post on your lanes and contact them directly next time
Load boards vs brokers
Both have a place. The difference is who keeps the margin and who owns the relationship.
| Load board | Freight broker | |
|---|---|---|
| Cost | Flat membership (Freight1: £51/vehicle/week); no cut of the job | Margin between shipper price and haulier rate, often unknown to you |
| Speed | Fast if you're active: you see loads as they post | Fast: the broker calls you |
| Rate | You negotiate directly with the shipper | Fixed by the broker |
| Relationship | You own the customer relationship | The broker owns it |
| Payment terms | Agreed directly | Broker's terms, sometimes 60+ days |
| Best for | Hauliers who want repeat customers and full rates | Hauliers with no time to plan, or urgent fill-ins |
Our recommendation: owner-drivers and small fleets should make a load board their main source and use brokers to plug gaps. Larger fleets with a planning desk will find a board pays for itself in a day or two of filled legs, and turning board contacts into direct customers is where the long-term value lies. For more on how boards work and what they cost, read what is a freight exchange.
Backloads by load type
The kit you run decides where your backloads come from:
- Container skeletals: return empty boxes to port or depot, or take export boxes back. Your backload is often the other half of the shipping line’s own move. See container loads.
- Curtainsiders and box trailers: the widest choice. Full loads and part loads of palletised goods on almost every lane. See full loads and part loads.
- Reefers: chilled and frozen food flows are unbalanced: plenty out of food production areas, less back in. Be ready to take ambient work on the return. See refrigerated loads.
- Flatbeds: steel, timber and construction materials. Return work often comes from builders’ merchants and steel stockholders. See flatbed loads.
- Vans: urgent same-day jobs both ways; the return leg is often an urgent part going back for repair. See van loads.
Groupage, mixed consignments, was the largest single commodity group carried by UK lorries in 2024, at about 24% of tonnage (DfT). If you run a curtainsider, part loads are the easiest backloads to find.

Some lanes are reliably unbalanced, which is exactly where backloads are easy to find.
- Felixstowe ↔ the Midlands via the A14 and M6/M1. Imports flood west; exports and empty returns come back east. Watch for A14 closures at the Orwell Bridge in high winds.
- Southampton ↔ the North West via the M3/A34, M40 and M6. Heavy import flow north; northbound hauliers can pick up manufactured goods from the M6 corridor coming south.
- London Gateway and Tilbury ↔ Manchester and Yorkshire via the A13, M25 and M1. Long lanes with good return potential from northern DCs.
- Liverpool ↔ Yorkshire via the M62. Short trans-Pennine trips where a backload can make two loaded legs in one shift.
- Hull ↔ the Midlands via the A63/M62 and M18/M1. Ro-ro and short-sea freight with steady return flows.
Before committing to a port backload, check the terminal’s booking rules. Felixstowe moved from its old Vehicle Booking System to a Container Booking Service in 2025, with charges for late changes and peak-time slots. Our container haulage guide explains slot booking at each port.
Inland rail terminals create backload flows too. Containers moved by rail to terminals such as DIRFT near Daventry, Hams Hall near Birmingham, Trafford Park in Manchester and iPort near Doncaster need road collection and delivery for the last few miles. Those short shuttles fit neatly around longer port runs.
Pricing a backload
Price a backload on your marginal cost, not your full-rate cost. You’re driving that way anyway, so the question is how much extra the load costs you: extra miles off your direct route, loading and waiting time, and any extra fuel for the weight.
As a reference point, recent container loads posted on Freight1 included London Gateway to Manchester (165 miles) at £900, Felixstowe to Newport (186 miles) at £920 and Felixstowe to Rochdale (185 miles) at £960, about £4.95–£5.45 per loaded mile. Backloads on the same lanes typically settle below those outbound budgets, but well above the zero you’d earn running empty. Short jobs are different: Liverpool to Manchester (28 miles) was posted at £390, because loading and waiting dominate.
| Factor | Pushes the rate up | Pushes it down |
|---|---|---|
| Detour from your route | More than 20–30 miles off line | On your direct line home |
| Waiting time | Slot-dependent terminal or long tip | Ready-loaded, quick turnaround |
| Urgency | Same-day, timed delivery | Flexible over 2–3 days |
| Weight / handling | Heavy box, hand-ball, tail-lift | Palletised, forklift both ends |
| Competition | Few trucks in the area | Busy lane, many trucks posted |
A useful rule: work out your marginal cost (use the calculator above), add the margin you need, and don’t go below it just to fill the truck. Agree waiting time and fuel terms in writing. Full rate tables are in UK haulage rates, and membership costs are on the pricing page.
Paperwork and payment terms
Treat a backload like any other job. Get the collection reference, delivery booking and agreed rate in writing. Get a signed or electronic proof of delivery, and invoice promptly. For a new customer, check the company on Companies House and agree payment terms before you load. Thirty days is common; anything longer should be priced in. On Freight1, keeping the agreement in the job’s message thread gives both sides the same record if there’s a dispute later.
Common backload mistakes
Most backloads that lose money do so for the same handful of reasons. Avoid these and the work you take on will pay:
- Accepting a port load with no slot. The rate looks good until the truck sits outside Felixstowe for half a day. Confirm release and slot first.
- Leaving waiting time vague. “Should be quick” is not a term. Agree free time and the hourly rate after it, in the message thread.
- Long detours for small money. A 60-mile detour for a £150 load can cost more than it earns once you count fuel and hours. Work out the marginal cost first.
- Not checking who you’re dealing with. Look at the poster’s profile, company details and ratings. If a job has passed through several hands, find out who the actual shipper is.
- Ignoring payment terms. A backload paid at 90 days isn’t the same as one paid at 30. Agree terms before you load and invoice the same day you deliver.
- Breaking your hours. A backload that pushes the driver past their daily driving limit or misses a break isn’t worth a fine or a delayed delivery. Plan it within the rules.
Write down the three things that went wrong on your last bad backload. Usually one of them is on this list.
Backloads for shippers: why flexible loads cost less
Backloads aren’t only a haulier’s tool. If you’re a shipper with goods that can travel any time over a day or two, you can often get a lower price by letting a haulier carry them on a return leg. The haulier is driving that way anyway, so anything above their marginal cost is welcome. Hauliers looking for backloads search by area and date, so the more flexible your window, the more trucks can fit you in.
To attract backload offers: post early (the day before or more), mark the load as time flexible, give a realistic budget, and make collection easy with forklift or dock and clear opening hours. Our guide to shipping freight in the UK explains how to post a load that gets good offers.
How Freight1 helps with backloads
Freight1 is built around the backload problem. Loads are filtered by category and collection area, so you see only work leaving the place you’ll be empty. Shippers can show a budget on the card, so you know whether a job clears your marginal cost before you call. You can post your truck as available so shippers come to you, save loads to favourites, and keep every conversation in a message thread attached to the job.
Once a job is agreed, tracking shows the shipper each step and an ETA, and a confirmed delivery opens ratings for both sides. Good backload work builds a visible record, and that’s what wins the next shipper’s trust and turns one-off returns into regular lanes.
Frequently asked questions
What is a backload in haulage?
A backload is a paid load a haulier carries on the return leg of a journey, so the vehicle doesn't drive back empty. It's also called a return load.
How do UK hauliers find backloads?
Mainly through load boards, by posting their truck's empty leg, asking the customers they deliver to, working with port forwarders, and building regular arrangements on lanes they run often.
Is it worth paying for a backload website?
Usually, yes, if you run empty legs every week. One backload on a 200-mile return can earn more than a month of Freight1 membership (£151 per vehicle).
How much should I charge for a backload?
Charge at least your marginal cost (extra miles, waiting time and fuel) plus a margin. Backloads often price below outbound rates but well above running empty.
Can owner-drivers get backloads?
Yes. Owner-drivers are among the biggest users of backload boards because one empty return can wipe out a day's profit.
Is there a free trial on Freight1?
Yes. Freight1 gives you 7 days of full access, including live loads, contact details and messaging, with no payment up front, so you can test it on your own lanes first.
Fill your next empty leg
Know your cost per empty mile, check the board where you’ll be tipping, post your truck, and price on marginal cost. Do that every day and empty running falls fast.
