Scaffolding hire periods explained: first period, extensions and standing time

Scaffolding is sold as a service with a beginning and an end, but most of the money lost on domestic and small commercial jobs isn't lost on the erect price, it's lost on the weeks the scaffold sits on site after the job it was built for has finished.

Get the hire period right, and word it so overruns bill themselves. It is the quickest money you will ever add to a scaffolding quote.

What the first hire period covers

The first hire period is the block of time included in your headline erect price before any extension charge kicks in. For domestic work this is commonly 4, 6 or 8 weeks; for commercial contracts it's often tied to the main programme with monthly hire built into the contract sum instead.

Pitch the first period too short and you'll be raising an extension invoice on nearly every job, which annoys clients even when it's contractually fair. Pitch it too long and you're giving away weeks of standing kit for free. Match it to a realistic programme plus a reasonable weather and delay buffer.

Weekly extension charges

Once the first period expires, hire should convert automatically to a weekly (or pro-rata daily) charge, not a renegotiation. A common yardstick is roughly 2–4% of the original erect price per week for domestic jobs, or a flat rate per metre run for larger commercial scaffolds. Whichever basis you use, state the actual £ figure on the quote itself, not just the percentage, so there's no ambiguity when week seven arrives.

For the full pricing method behind these numbers, see our guide to pricing a scaffolding job and our per-metre rate guide.

Standing time vs hire charge

"Standing time" is sometimes used loosely to mean the same thing as an extension charge, but it's worth separating two different situations on a quote:

• Extended hire. The scaffold is still needed and doing its job, just for longer than planned. Charge the weekly extension rate.
• Standing idle awaiting instruction, the scaffold is up but no one's working from it (client not ready, access blocked, permissions pending). This is where a separate "standing time" clause matters, because it's a delay outside your control that still ties up your kit and crew availability. Price it the same as extended hire, but flag it in your correspondence as idle time so there's a written trail if it becomes a dispute.

Wording it so overruns bill automatically

The wording on the quote is what actually protects you, not the intention behind it. A clause that works in practice does three things: states the first period in weeks from a clear start date, states the exact weekly rate for any extension, and states that extension charges apply automatically without further notice. For example:

"This quotation includes scaffold hire for 6 weeks from the date of erection. Hire beyond this period will be charged at £45.00 per week (or part week), invoiced monthly in arrears, and will continue to apply automatically until dismantle instructions are received in writing."

That wording removes the awkward phone call. The client agreed to it up front, the invoice matches what they signed, and there's nothing to negotiate when week nine rolls around. It's also worth cross-referencing this clause with your wider quote terms and conditions so the hire clause isn't sitting in isolation.

Worked example

Loft conversion scaffold: erect price £1,400, first hire period 8 weeks, extension rate £35/week. The job overruns by 3 weeks due to a delayed building control sign-off.

£105 might look trivial next to a £1,400 job, but multiply that across every job that overruns in a typical year and it's the difference between a scaffold yard running at a loss on hire and one that's covering its kit properly.

Common questions

Can I charge for hire if the client says the scaffold wasn't needed?

If the scaffold remained erected on their instruction, or no dismantle instruction was given in writing, then yes. Provided your quote wording makes hire continue automatically until instructed otherwise. This is exactly why the clause needs to be explicit rather than implied.

Should extension rates be a flat fee or a percentage?

Either works, but state a cash figure on the quote either way. Percentages are fine for internal rate-setting; clients need to see an actual £ per week so there's no dispute about what "3%" means in pounds.

Does VAT apply to hire extension charges?

Yes, at the same rate as the rest of the scaffolding supply, normally standard-rated at 20% unless the job qualifies for a reduced or zero rate under the usual construction VAT rules (for example certain new-build work).
