FAQs

How do I order samples?

Before ordering worktops from us, you may want to order worktop samples. All types of worktop samples can be ordered online on our samples page.

Do you sell custom sized worktops?

We offer a wide variety of customisation to our worktops, please check out our Online Bespoke Tool to see all the great options to customise your worktop.

What are the benefits of laminate worktops?

Laminate worktops are a fantastic choice for your kitchen! They’re easy to install with no specialist tools needed, making your DIY project a breeze. Plus, they’re budget-friendly and come in a stunning range of decors and sizes to fit any style. Durable and hard-wearing, laminate worktops can handle the demands of daily life while looking great.

Can I order a laminate worktop sample?

Yes, you can! We offer samples for all our worktops so you can see and feel the quality before making a decision. You can order your samples here and start envisioning your new worktop.

Can you customise my laminate worktop?

Absolutely! Our customisation service covers everything from cutting to size, creating sink or appliance cutouts, edging, joining, and more. Find out all the details and get started on your tailored worktop by visiting our customisation services page.

Do I need extra edging strips?

Some of our laminate worktops come with additional edging included. To check if your chosen worktop has extra edging strips supplied, simply refer to the specification table for your worktop.

What’s the maximum unsupported overhang on a laminate worktop?

The maximum unsupported overhang for a laminate worktop is 200mm. This is perfect for a small breakfast bar overhang, giving you extra space without compromising stability.

Can you fit my worktop?

While we don’t offer fitting services, we highly recommend using a registered tradesperson for your worktop installation. A professional will ensure that your worktop is fitted accurately and securely, giving you peace of mind and a perfect finish. Look for tradespeople in your area with good reviews and credentials for a smooth installation process.

How can I fix a bowed laminate worktop?

Assess the Cause: Determine why the worktop has bowed. Common reasons include changes in humidity or moisture content, improper installation, incorrect storage, or structural issues.
Evaluate Damage: Check if the bowing is minor or severe. Minor bowing might be less of an issue and easier to correct.
Avoid Cutting or Installing: If the worktop is significantly bowed, avoid cutting or installing it. Contact us to see if it can be replaced.
Reduce Moisture Exposure: If the bowing is due to moisture, try to reduce exposure to moisture sources. Ensure there are no leaks from nearby sinks or taps.
Weight Distribution: Place heavy objects or weights evenly across the bowed area to gradually encourage it to flatten out. Use something like heavy books or bags of flour for a couple of days.
Flip the Worktop: If the worktop is not fixed in place permanently, flipping it over might reveal a flatter surface on the other side.
Consult a Professional: If the bowing persists or is severe, consult a professional carpenter or installer. They can assess the situation and provide expert advice on how to fix or replace the worktop if necessary.
Prevent Future Issues: Once the worktop is corrected, take steps to prevent future bowing by ensuring proper installation, oiling, and maintenance.

Depending on the severity and cause of the bowing, one or more of these steps should help alleviate the issue. If you're unsure or uncomfortable tackling this yourself, it's always wise to seek professional assistance.

Do you sell offcuts?

Whenever you customise your worktop using our Worktop Customisation Tool, we will send you all of the pieces that are removed in order to create your perfect shape. Unfortunately, we do not hold or sell any offcuts separately our customer always receives all of the worktop they purchase (apart from any non-viable slivers!). If you want a smaller piece of worktop, our bathroom worktops, are a great option for people looking for a small worktop section.

600mm Wide: 1 x Finished long edge
