We offer fast, tracked delivery across the UK, using recognised couriers including Royal Mail, DHL and Parcel Force.
Shipping to Europe or North America? We now deliver to both from our dedicated regional stores. Visit our Europe store or North America store for pricing and delivery to your region.
How delivery is priced
Delivery is charged on the longest side of your panel, rather than its area or weight.
A sheet measuring 1500mm × 1000mm is priced on its 1500mm side; a long, narrow strip of 2200mm × 150mm is priced on its 2200mm side. Whichever single dimension is longest sets the price.
Only one delivery charge applies per order, however many pieces you order.

Delivery times
- Standard — 3–5 working days

Next-day delivery
We don't offer next-day delivery online due to the volume and the bespoke, made-to-measure nature of the orders we handle each day. If you're working to a deadline, get in touch — we'll do everything we can to meet it.
UK remote areas
Because we supply made-to-measure products, we offer delivery at standard national rates wherever we can. A small number of locations cost us more to reach, so a remote area supplement is added automatically at checkout:
| Longest side | Remote area supplement |
|---|---|
| Samples (100mm × 100mm) | £0.00 |
| Less than 500mm | £0.00 |
| 500mm – 1499mm | £10.00 |
| 1500mm – 2499mm | £15.00 |
| 2500mm or greater | £20.00 |
All prices include VAT.
Locations that may incur a supplement include the Channel Islands, Isle of Man, Isles of Scilly, Isle of Wight, the Scottish Islands and Highlands, remote areas of Scotland, and Northern Ireland.
In rare cases, an order to one of these areas may be economically unviable to fulfil. If that happens, we'll always contact you first to discuss options before taking any action — we won't simply cancel.
Third-party deliveries
Some products are dispatched directly from the manufacturer via a third-party courier. Where this applies, it's clearly stated on the product page under the Delivery tab.
Can I collect my order from Simply Plastics?
Yes, of course. Orders can be collected from our premises in Colchester, Essex. At the final stage of the checkout process there is a delivery option labelled "Collection/pickup" which is free. Once your order is complete, you will be notified by email along with our address and collection times.
I need my order urgently, can I pay for faster shipping?
Yes. We offer an express delivery service which aims to deliver all orders in 1-3 working days. Orders are delivered by a recognised courier company and may require a signature on delivery.
Where do Simply Plastics deliver?
We deliver across the UK, to 12 European countries (Austria, Belgium, the Czech Republic, France, Germany, Greece, Ireland, Italy, the Netherlands, Poland, Portugal and Spain) and to the United States and Canada.
International orders are placed through our dedicated regional stores, with pricing in your local currency and all import taxes and duties settled at checkout — so your order arrives with nothing more to pay. EU businesses with an EORI number can also choose to act as the importer of record.
For full pricing, delivery times and customs information, see the delivery information page on our UK, Europe or North America store.
Do you have a minimum order charge or small order fee?
This is a question we are asked fairly regularly due to the previlance of either a minimum order charge or small order fee within the industry.
At Simply Plastics our approach has always been to treat all orders equally, small or large. We want all customers, new and existing, to be able to place orders with us confident that they are only paying for the products and materials that they require. We therefore do not have a minimum order charge or small order fee.
How should I clean polycarbonate sheet?
Polycarbonate sheet should not be cleaned using chemical cleaners because they can cause damage to the material. We recommend cleaning polycarbonate sheet with warm soapy water and a soft cloth. There are various plastic cleaners and polishers available which we can provide that keep polycarbonate looking brand new.
Is it possible to cut polycarbonate sheet myself?
Polycarbonate sheet can be cut using a circular saw, a jigsaw or any type of saw with a fine-tooth blade. We recommend laying the polycarbonate sheet flat on a firm surface, such as a workbench, and clamping it down before cutting. If you are using clamps to hold the material down, we suggest placing wood between the clamps and polycarbonate sheet to prevent any damage to the surface of the polycarbonate. Manufacturer safety precautions should always be followed when using any type of saw. See our ultimate guide to polycarbonate for more information on polycarbonate and it's uses.
