Rain, Wind and the Running Clock: Keeping a Winter MEWP Hire From Eating Your Margin

The forecast is not a variation order

A MEWP hire looks beautifully simple on paper: you book a machine, it arrives, the meter starts, the work gets done, the machine goes back. Winter has a habit of inserting a paragraph nobody read. The wind picks up, the platform gets parked, the operatives go and stand in a canteen, and the hire clock keeps ticking like a taxi waiting outside a restaurant.

That is the bit worth getting straight before the machine rolls onto your yard in winter 2026/27. Weather is not automatically a free pass. In most hire arrangements, the equipment is on hire until it is formally off-hired, not until the weather turns grim. If the job stops because the platform is outside its wind limit, the commercial question is not “whose fault is the weather?” — it is “what does the agreement say about non-productive time?”

What the hire agreement is actually doing

Standard plant hire terms tend to put the risk of site conditions on the hirer. That is not a conspiracy; it is how the hire model works. The supplier owns the machine and expects a rate for its availability. You control the site, the programme and the decision to send it back.

Ordinary winter weather is also rarely a force majeure event. Snow, rain and wind in November are not exactly unforeseen. So if your plan assumes the hire company will waive charges for a wet week, check that assumption before you sign. The relevant questions are usually quite dry:

• When does the hire period start and end?
• Is there a minimum hire period?
• How much notice is needed to off-hire?
• Are transport and collection charges payable either way?
• Does the agreement mention weather, suspension or standing charges?
• What happens if the machine is kept on site “just in case”?

If the answer to the last one is “you pay for it”, that is not a trick. It is the hire clock doing its job.

Wind limits are a number, not a vibe

Every MEWP has a rated wind speed, and it is not the same for every machine. The figure that matters is the one in the manufacturer’s manual and the machine’s documentation, not the one somebody remembers from a previous job. Some platforms are fine in a stiff breeze; some are not. Add a large sign, a sheet of cladding or a person acting as a human sail, and the practical limit can arrive earlier than the paperwork suggests.

That matters commercially because wind stops work in a way rain often does not. A bit of drizzle might slow a job; a gusty day can park the whole platform. The useful move is to agree, in advance, who decides when the platform comes down and what happens to the day’s charge. A site anemometer and a nominated person are not bureaucracy — they are how you avoid an argument at invoice stage.

Ice is the quieter one. Access around the machine, the basket, the steps and the ground can become the limiting factor before the wind does. Again, the question is not just safety. It is whether the machine is sitting idle on hire while everyone waits for a thaw.

‘Weather days’ need a definition

“Weather day” sounds like a term of art. In practice it can mean anything from “the lads got wet at lunchtime” to “the site was formally closed by the principal contractor”. If you want to rely on it, define it.

A workable definition might be tied to the manufacturer’s wind limit, a site closure notice, or a documented decision by the site manager. The point is to create a record that both sides recognise. A WhatsApp message saying “too windy” is not a contractual event. A dated site diary entry, a wind reading and an email to the hire desk is much closer.

It is also worth deciding whether a weather day pauses the hire, reduces the rate, extends the hire period or does nothing at all. Those are four very different outcomes. The cheapest-looking hire rate can become the most expensive one if every windy day is billed at full rate and the job overruns by a fortnight.

Negotiate before the machine moves

The best time to talk about weather risk is when you are still comparing quotes. Suppliers would rather keep a sensible customer than argue over a stalled week, and there is usually room to shape the deal if you ask early.

Things worth putting on the table:

• A pre-agreed weather allowance — for example, a set number of non-productive days at a reduced standing rate.
• A suspension clause that applies when the platform is outside its rated wind speed or the site is formally closed.
• A clear off-hire notice period, ideally short enough to stop a dead machine burning money.
• Collection and re-hire costs confirmed up front, so a temporary off-hire does not trigger a nasty haulage bill.
• A rate lock for any extension caused by weather, rather than a new weekly rate halfway through the job.
• Permission to swap to a smaller or different machine if the weather suits it better.

None of this is about being clever with the supplier. It is about pricing a risk you can actually see coming. Winter in the UK is not a surprise guest.

Keep the paper trail short and brutal

Once the machine is on site, a little discipline goes a long way. Log the weather decision daily: time, wind reading, what was parked, who made the call. Photograph the conditions if it helps. Tell the hire desk the same day, not three weeks later when the invoice arrives.

If the job is stalled for several days, do not let the machine sit there out of politeness. Ask the commercial question: is it cheaper to off-hire and re-hire, or keep it on a reduced standing rate? Sometimes keeping it is the right answer. Sometimes it is just the expensive answer with fewer phone calls.

The margin is in the boring bits

Winter MEWP hires do not usually fail because of one dramatic storm. They fail because a few windy days, a frozen access route and a machine kept on hire “until things improve” quietly add a week to the bill. The operators and site teams will handle the practical side. The commercial side needs somebody to read the agreement, define the weather day, agree the cut-off and keep the hire desk in the loop.

Rain and wind are not billable items in themselves. But the way you handle them can decide whether the job makes money or simply makes a story. Build the weather contingency into the booking, not the post-mortem.
