Benchmarx kitchens review - by owners and experts

It offers two core ranges – the factory-assembled Grey Cabinet and the Essence Flatpack, which is a budget range available in fewer styles and colours.
Read on to find out how these Benchmarx kitchens performed in our lab tests, and how satisfied owners are with their purchase.

How we test our kitchens
In the lab
We buy all of our kitchens at market price and send them to a specialist laboratory, where expert assessors run 19 tests across four key areas.
Our surveys
We survey Which? Connect members and the UK public who've bought a kitchen in the past 10 years. We never ask people to test kitchens for us.
Editorial independence
The writer and editor have no contact with the brands, laboratory, or survey respondents during the testing process.
More than just reviews
Which? members can also access our expert kitchen planning, budgeting, and money-saving tips.

Table notes: Damage and repairs based on an online survey of 2,496 people Which? Connect members and members of the UK public who reported buying a kitchen between 2015 and 2021, conducted in February and March 2025. Benchmarx sample size: 41.
On average, across all the brands we collected data for, 44% of survey respondents reported that their kitchen was showing signs of damage or wear and tear after at least five years of ownership.
The most common issue was the finish of the cabinets being scratched (15%) and the soft-close mechanisms failing (12%).
In contrast, just 34% of owners from the most reliable brand reported damage to their kitchen.

Benchmarx kitchens cost
To find out how much you can expect to spend, we set up mystery shopping appointments to source prices for all the kitchens we test.
| Kitchen | Range | Price | Discount applied |
|---|---|---|---|
| Essence Flatpack | Cashmere Grey | £2,369.61 | Not given |
| Grey Cabinet | Cambridge Taupe | £4,337.57 | Not given |
Table notes: Price data is for a 12 unit kitchen, including handles, cornices, plinths, pelmets and end panels. Prices include VAT and sales discounts. Installation is not included. Prices were collected in May 2025, and are subject to change.
Mystery shopper methodology: We found the middle-priced range for each kitchen carcass we test (based on the median average), then attended design appointments with every brand, posing as a customer looking to buy a new kitchen. We asked brands to provide us with prices for the selected ranges in a 12 unit kitchen, without any additional accessories (such as worktop, sink, taps or appliances).
We were quoted between around £2,500 and £4,500 for the Benchmarx kitchen we designed.
These prices both include a discount, but the exact percentage was not specified in the quote we were sent.
We had to make two minor changes to the Flatpack design to ensure it was as consistent with other kitchens as possible. We added an extra base cupboard, as the other base units are slightly smaller than in our design, and a pre-built oven unit, as the Flatpack range does not include this item.
Bear in mind that this is based on one design appointment and should be used as an indicator of how much you can expect to pay. You may be quoted a different price.
Installation is not included.
