At a glance: How to plan timber deliveries (and avoid site delays)
- Plan by programme: Break orders into phases (first fix, boarding, second fix, formwork cycles) instead of ordering everything at once.
- Confirm specs early: Check grade (e.g. C16/C24), treatment, sizes, and sheet types – and avoid last-minute substitutions.
- Send proper site details: Include postcode, contact number, access notes, offload point, opening hours, and any timed slot requirements.
- Prepare storage: Make space, protect materials from weather, and stack logically to reduce damage and re-handling.
- Choose a responsive merchant: Account-managed support and clear communication help you adapt when programmes change.
- Check on arrival: Verify quantities/specs and flag issues immediately to prevent downtime later.
Share your drawings/spec – or simply your quantities, postcode, and delivery date – and South London Timber will help you plan the right deliveries at the right time, keeping your site moving.
On a live construction site, delays rarely come from one big problem – instead, they come from multiple small issues stacking up over time.
A missing pack of carcassing timber; a delivery turning up without the right access notes; sheets arriving before you’ve got space to store them – all of this costs time, labour, and momentum.
Timber is one of the most frequently ordered materials on many builds, and it’s often needed at the exact moment a workfront opens up.
That’s why planning your timber deliveries properly is one of the simplest ways to protect your build programme.
At South London Timber, we work with everyone from local builders to large construction teams, helping you plan supply so the right material lands on site at the right time.
We pride ourselves on clear communication and reliable delivery across Kent and South East London – with wider UK delivery options available for qualifying orders, subject to volume, location and transport availability.
This guide shares our top tips on how to plan timber deliveries to avoid delays on site, based on over 30 years of experience supplying the construction trade.
1. Start with the programme, not the product list
It’s tempting to order everything at once, especially if you’re trying to get ahead.
But one bulk delivery can cause storage problems, damage risk, and wasted handling time.
Instead, break your project into phases:
- First fix framing (studs, joists, carcassing)
- Decking/boarding (plywood, OSB3, structural sheets)
- Second fix / finishing (PAR, joinery softwood, MDF)
- Formwork cycles (panels, timber, repeat pours)
Then order timber in line with your programme milestones. This will reduce congestion, minimise re-handling, and keep work moving.
If you’re not sure what should arrive when, just ask our expert team. We can help you plan the sequence, not just take the order.
2. Confirm specifications early – and avoid last-minute substitutions
One of the most common causes of delay is incorrect or unclear specification, especially around:
- C16 vs C24 structural grades (find out the difference and learn which type you need)
- Treated vs untreated timber (read our treated timber guide)
- Sheet material type (plywood vs OSB3 vs MDF)
- Lengths, thicknesses and grades
If you’re working from drawings, make sure the order matches the spec. If you’re not, do a quick internal check with whoever is responsible for structural decisions.
And if stock availability ever becomes an issue, don’t substitute without checking – swapping grades or treatment levels can create compliance problems and rework.
The South London Timber team can sanity-check your order against your application, helping you avoid the wrong product landing on site.
3. Give your supplier proper site information (this is where most issues happen)
A delivery can be “on time” and still cause delays if the driver can’t access the drop, can’t find the right gate, or arrives during a site closure.
So when you place an order, ensure you provide:
- Full delivery address and postcode
- Site contact name and mobile number
- Opening hours and any delivery restrictions
- Access notes (width/height limits, gates, one-way systems)
- Where to offload (designated area, level, zone)
- Whether you need a timed slot
- Any rules like PPE, induction, or booking-in procedures
If your site uses a delivery booking system or requires pre-notification, include those details when ordering to avoid failed drops and downtime.
This is especially important on busy sites, city centre locations, and jobs with tight access or neighbours.
As a simple rule, if your supplier has to guess, the site loses time.
4. Plan storage and protection before the truck arrives
Timber and sheet materials are durable, but they’re not invincible.
Poor storage causes:
- Warped boards
- Moisture damage
- Delamination risk for sheets
- Wasted time sorting and rejecting materials
So before delivery day, make sure you plan:
- Clear drop space close to the work area
- Protection from weather (covers, pallets, separation from ground)
- A logical stacking system by phase/use
- A “first in, first out” approach for ongoing works
If you don’t have space, order in phases. A well-planned phased delivery often saves more money than it costs.
5. Order with contingency, but don’t over-order
Running short on timber mid-task can stop construction in its tracks, while over ordering creates clutter, damage risk, and wasted spend – so it’s important to get this balance right.
A smart approach is to:
- Build in a small contingency for common items (e.g. studwork, noggins, packers)
- Keep the main supply phased
- Track usage weekly so you can top up before you run out
If you’re on a repeat programme, we can help you standardise quantities and re-order patterns to keep supply consistent.
6. Use a merchant who can support repeat orders and programme changes
We know that programmes change, deliveries move, and quantities evolve. And we also know that suppliers who keep projects moving are the ones who communicate clearly and adapt quickly.
That’s where working with a dedicated account manager makes a difference. Instead of re-explaining everything on every call, you’ve got a direct point of contact who knows:
- What you’re building
- What’s already been delivered
- What’s due next
- What the critical path is
South London Timber’s team is built around this kind of support – helping trade customers plan deliveries, adjust schedules, and keep procurement simple from start to finish.
7. Check deliveries on arrival – and flag issues immediately
This may sound obvious, but it’s always worth a reminder – because ensuring deliveries are accurate prevents big problems down the line.
So, on arrival you should:
- Check quantities against the order
- Confirm grade/treatment where relevant
- Inspect sheets for obvious damage
- Store correctly straight away
If something isn’t right, raise it immediately – it’s much easier to resolve on day one than after installation has started.
