A hard-wearing, hygienic worktop is essential for any modern kitchen. Whether you’re fitting a new worktop or replacing an old one, there are a huge range of styles, designs and materials to choose from to suit your needs and preferences.

The most popular kitchen worktops are made from laminate, solid wood, compact laminate, quartz and granite. Each of these materials have slightly different cutting and fitting requirements. Only qualified professionals should cut and fit stone and granite kitchen worktops. However, it’s fairly straightforward to fit the other types yourself, as long as you’ve planned and prepared thoroughly.

In this guide, we’ll cover how to pre-cut and fit laminate worktops, leaving you feeling confident you'll get the job done right. If you’re ever unsure about any particular step, check our handy how-to video.

Measure twice to plan cuts, keeping joints supported and at least 100mm away from sinks.
Acclimatise solid wood worktops horizontally for 24 hours on the floor before installation.
Secure pre-cut sections to base cabinets from underneath using screws.

Planning and Preparation

First of all, it's important to plan how much work surface you'll need, and where any cuts are going to be made. The following tips may help your planning:

Avoid mistakes by measuring twice, so you only need to cut once
Try to make the best use of the factory-cut edges in your planning, so you keep your own cutting to a minimum. Factory-cut edges will always be perfectly square
Plan so that any joints are properly supported by the unit frames beneath
Make sure any joints between pieces are at least 100mm away from any sinks or cut-outs for appliances
Position any hob cut-outs at least 50mm from the front edge and 60mm from the rear edge

It’s important to let your worktops acclimatise for 24 hours after they’ve been delivered, so we suggest stacking them horizontally on the floor, separated by packers or blocks of some kind. After 24 hours, we recommend you fit them as soon as possible.

Keep the protective plastic covering on the unit door fronts until your worktops have been fully installed.

Tools and materials

Cutting kitchen worktops

If you’re cutting laminate, compact laminate or solid wood worktops, there are a few basic rules to follow to ensure that you’re safe and you make a clean cut.

Make sure your worktop is firmly secured before you start sawing. A circular saw with a fine-tooth, thin blade is best for cutting the worktop. You should clamp down a straight edge to guide the saw
When using a hacksaw or power saw, wear safety goggles and a dust mask, and make sure the room is well-ventilated
If possible, practice cutting on a small piece of excess or offcut worktop first. This way, you'll get used to the method.

If you need to trim or cut the worktop to length, mark a cutting line on the underside with a pencil. Double-check the measurements and then cut using a power saw. Use a file or sandpaper to smooth down any rough edges.

Due to the length and weight of the worktops, you will usually need somebody to help you install them.

How to install your kitchen worktop: step-by-step

Once your cuts are finished, follow these eleven steps to complete your kitchen worktop installation.

Position the pre-cut laminate worktop sections on the base units, checking that the overhang is the same across all lengths. In this guide we’re working with standard 600mm deep units which have a 10mm overhang at the front. The worktops have also been cut to allow a 20mm overhang at the ends.

Once you’ve put the worktops in place, check the fastening positions.

To join two pieces of worktop, measure the width of the worktop and cut a joining strip to the same length, using a hacksaw.

Place the joining strip against one of the cut edges and screw it into place using the pre-drilled holes in the strip.

Apply some silicone sealant to the joining strip before pushing it into position against the adjoining worktop. Double-check to make sure the join is clean, neat and even.

Clamp the worktop onto the base units and fix from the underside. Some manufacturers provide brackets or fixing blocks with the worktops.

Set the length of your drill bit to less than the depth of the worktop, to prevent drilling through. Drill three holes in each of the back and front support struts that are attached to the cabinet: a hole at either end of the strut and one in the middle.

Screw the units to the worktop using 5mm diameter wood screws. Be careful not to over-tighten the screws.

To finish a cut end, use the strip supplied with the worktop. Tape it to the end of the worktop and run a pencil around the edges to create an accurate template. Remove the end strip and carefully cut along your lines to make the template.

Put down a strip of masking tape running along the top edge of the worktop. This helps protect it from the contact adhesive you’re about to use.

Carefully brush contact adhesive onto the end strip and the end of the worktop. Wait 15 minutes before fixing the end strip in place.

Peel off the masking tape, and if the end strip still protrudes slightly then use a file or sandpaper to smooth it down.

Fitting a kitchen worktop can be a highly rewarding project that will transform your space and save money on labour costs. By taking the time to plan cuts and seal joints correctly, you'll ensure a beautiful and durable finish.

FAQs

Cut a joining strip to the same length as your worktop width with a hacksaw. Place the strip against one of the cut edges and secure it with screws. Apply silicone sealant along the joint and push the adjoining worktop against it to create a neat, watertight seal.

It’s possible, however, in the interests of safety and stability, we always recommend fitting kitchen worktops directly onto solid base units. If your layout requires a worktop with no cabinets underneath, please contact a professional installer for advice.

The cost of installing a kitchen worktop surface will vary depending on the materials used and the size of the kitchen. However, learning how to fit a kitchen worktop yourself is a brilliant way to save on labour costs, requiring only standard tools and materials.
