The cabinets are the part of a kitchen nobody sees once the doors are on, yet they decide how long it lasts, how quickly it goes in and how often you get called back to it. For fitters, joiners, kitchen studios and housebuilders, choosing where to buy trade kitchen cabinets is less about the look and more about the carcass spec, how the units arrive, how easy they are to get hold of and what happens if something goes wrong.
UK suppliers take quite different approaches. Some supply flat-pack carcasses that are cheaper to deliver and store, others send rigid units ready to fix to the wall. Some sell strictly to the trade through accounts and local depots, while others make to order and deliver direct. Below are five suppliers worth comparing, with details taken from what each one publishes on its own website, followed by a guide to what to check before you order.
1. HPP – a good fit for trade buyers who want cabinets, doors, worktops and board on one order
HPP (Hill’s Panel Products Ltd) is a family-owned, trade-only supplier based in Oldham that has served the fitted furniture industry since 1991. Its trade kitchen cabinets are supplied flat-pack with the fittings included, and sit alongside the doors, worktops, board and Blum fittings it also stocks, so a whole job can go on one order.
- Construction: the EasyCab range uses cam and dowel assembly, with 18mm MFC panels and PVC edging made from FSC-certified chipboard with an antibacterial melamine surface.
- Backs and rails: 18mm top rails and backs on all base units, 6mm backs on wall units and 18mm adjustable shelves.
- Fitting details: adjustable legs from 132mm to 200mm, and pre-drilling for doors and drawers with hinge holes at 100mm centres.
- Carcass colours: White and Light Grey.
- Sizes: base units from 150mm to 1000mm wide, wall units from 300mm to 1000mm and tall units at 1970mm and 2150mm, plus corner and oven housing options.
- Stock and delivery: more than 7,000 products, with almost all off-the-shelf lines available for next-day delivery nationwide.
Worth knowing: HPP sells only to the trade, and pricing is shown through a trade account. Its cabinets are flat-pack only, so they need assembling before fitting, which HPP says keeps them cost-effective to buy and deliver.
Suited to: fitters, joiners, kitchen studios and housebuilders who are happy to assemble carcasses and want to source the whole kitchen from one trade supplier.
2. Howdens – a good fit for trade buyers who want local depot stock and rigid or flat-pack options
Howdens describes itself as the UK’s number one trade kitchen supplier, citing a Mintel report from September 2025, and it sells only to the trade. Founded in 1995, it manufactures its cabinets in the UK and supplies from local stock through more than 850 depots across the country.
- Cabinet options: ready-assembled, flat-pack and handleless units.
- Guarantee: a 25-year guarantee on all cabinetry, which is also FIRA Gold certified.
- Recognition: Howdens says its rigid cabinets were accredited as a Which? Best Buy in June 2026, for the fifth year in a row.
- Carcass colours: white, natural oak and natural walnut, with a chart on its website showing which door colours each one is designed to complement.
- Fitting details: ready-assembled wall cabinets in 360mm, 720mm and 900mm heights, 72mm service voids for cables and pipes, and standard 110-degree hinges with a 170-degree upgrade.
- Design and range: a free design and planning service at every depot, more than 100 kitchen designs and more than 10,000 products across kitchens, joinery and hardware.
Worth knowing: because Howdens is trade-only, homeowners usually buy through their fitter. Its website shows prices and stock only once you sign in to a trade account.
Suited to: fitters and builders who value collecting from a nearby depot, a long cabinet guarantee and in-depot design support for their customers.
3. Magnet Trade – a good fit for fitters who want credit terms and install-friendly rigid cabinets
Magnet Trade is the trade arm of Magnet, with more than 195 showrooms nationwide. Trade account holders get exclusive discounts, flexible finance options and 60-day credit terms, and Magnet Trade says it has held FIRA Gold accreditation for more than 30 years.
- Install-friendly features: Magnet Trade says recent changes to its cabinets save 20% on installation time, including removable 6mm back panels for pipe access, a free adjustable wall spacer with every cabinet and legs that knock in without screws.
- Construction: Magnet’s cabinet buying guide states that its cabinets use 18mm-thick panels as standard and are manufactured in the UK.
- Guarantee: Magnet says all of its pre-built cabinets carry a lifetime guarantee.
- Carcass colours: mainly white, with oak and anthracite available to match doors in the Ascoli range.
- Design and quotes: a 24-hour kitchen design and quote service, plus free design quotes and site measures.
- Price promise: Magnet Trade says it will beat any quote by at least £50, or give you £50.
Worth knowing: some cabinet details, including the lifetime guarantee, are set out on Magnet’s main website rather than the trade site, so it is worth confirming the terms that apply to trade orders when you open an account.
Suited to: fitters who want trade credit, a large showroom network to send customers to and cabinets designed to speed up installation.
4. Benchmarx Kitchens & Joinery – a good fit for trade buyers who also use Travis Perkins
Benchmarx is part of the Travis Perkins group and states that it sells only to the trade. Since 2020 a Benchmarx trade account has also worked with Travis Perkins, so one account covers kitchens, joinery and the wider builders’ merchant range, and Benchmarx says its top-selling kitchens are held in stock at local branches.
- Construction: 18mm thick cabinets, with base and wall units supplied rigid for strength and fast installation.
- Back panels: 12mm on base units and 8mm on wall units.
- Hardware: soft-close Blum drawers and hinges as standard, a metal cover for the wall-hanging brackets, and Häfele Axilo feet with a push-to-fit plinth system.

- Carcass colours: white, plus a newer deep grey option.
- Range and design: an Essence flat-pack kitchen range alongside its rigid units, and free design consultations that can be booked online.
Worth knowing: pricing and ordering run through a trade account, and as with any supplier it is worth checking the guarantee cover that applies to your order before you buy.

5. DIY Kitchens – a good fit for buyers who want made-to-order rigid units delivered direct
DIY Kitchens is a UK manufacturer with a factory in West Yorkshire, where it has been making kitchen units for more than 30 years. Unlike the other suppliers here, it supplies both trade and retail customers, and advertises its kitchens at manufacturer prices.
- Construction: rigid cabinets, with carcass ends, shelves and base panels in 18mm MFC and 2mm ABS edging on the front edge.
- Hardware: Blum Clip Top metal hinges with 3-way adjustment and soft close on every cabinet, plus Kessebohmer wirework.

- Choice: more than 100 kitchen ranges and more than 1,500 unit and door options.
- Lead times: usually 2 weeks from order to delivery, or 3 weeks for a bespoke painted finish.
- Delivery: its own fleet of delivery vehicles, mainland UK only, with a standard charge of £99 for most of the UK.
Worth knowing: units are made to order rather than held in local depot stock, so DIY Kitchens suits planned jobs better than urgent replacements, and planning and ordering are mainly done online.
Suited to: self-builders, renovators and fitters who want rigid, colour-matched units from a single manufacturer and can plan around a short made-to-order lead time.
How to choose trade kitchen cabinets
All five suppliers above build around an 18mm carcass, so the differences are mostly about how the units arrive, how you buy them and what support comes with them. These are the points worth checking before you commit to a supplier.
Flat-pack or rigid
Flat-pack carcasses take up less space in a van or on site, usually cost less to deliver and can be built in the room where they will be fitted, which helps with tight access. Rigid units arrive assembled, saving time on site, but are bulkier to transport and store. Many fitters use flat-pack for some jobs and rigid for others, so a supplier offering the option you need is more important than either format being better in general.
Carcass specification
Look past the board thickness to the back panels, top rails and edging. A thicker back on base units adds rigidity, while removable or recessed backs and service gaps make it easier to work around pipes and cables. Check the edging type and thickness, how the hinges are pre-drilled and whether the legs adjust far enough for uneven floors.
Sizes and configurations
A wide spread of widths, from narrow 150mm base units up to 1000mm, together with corner, bridging, tall and oven housing units, reduces the need for fillers and site modifications. Check that wall and tall unit heights line up with the door sizes you plan to use.
Colour matching
Carcass colour shows on open shelving, glass-fronted wall units and whenever a door is open. White suits most schemes, while grey, oak and anthracite carcasses can work better with darker or wood-effect doors.
How you buy
Trade-only suppliers usually show pricing through an account and may offer credit terms, depot or branch stock and a design service. Made-to-order suppliers deliver to site on a fixed lead time. Decide whether you need same-day or next-day availability, or can plan around a lead time of a couple of weeks.
Guarantee and after-sales
Published cabinet guarantees vary considerably between suppliers, from a set number of years to lifetime cover. Check what the guarantee covers, whether it depends on professional installation and how claims are handled.
One supplier or several
Buying cabinets, doors, worktops and fittings from the same source can simplify ordering and deliveries, especially on multi-plot or repeat work. It also makes it easier to check that door sizes, hinge positions and carcass dimensions all line up.
Final thoughts
There is no single best supplier of trade kitchen cabinets, because the right choice depends on how you buy and fit. If you want flat-pack carcasses on the same order as your doors, worktops and board, HPP is worth considering. Howdens, Magnet Trade and Benchmarx suit trade buyers who value rigid units, local stock and depot or branch support, while DIY Kitchens offers a made-to-order route for those who can plan around a short lead time. Whichever you shortlist, compare the carcass specification, guarantee terms and trade-account conditions side by side before committing to a supplier for repeat work.
Frequently asked questions
What are trade kitchen cabinets?
Trade kitchen cabinets are carcasses and units supplied to kitchen fitters, joiners, builders and studios, usually through a trade account with trade pricing. They are normally sold without doors or worktops, which are ordered separately to suit each job.
Can homeowners buy trade kitchen cabinets?
Some suppliers, such as HPP, Howdens and Benchmarx, sell only to the trade, so homeowners would buy through their fitter. Others, such as DIY Kitchens, supply both trade and retail customers.
Are rigid kitchen cabinets better than flat-pack?
Not necessarily. A well-specified flat-pack carcass in 18mm board can make a sturdy cabinet once it is properly assembled. Rigid units save assembly time on site, while flat-pack units are easier to deliver, store and carry into awkward spaces. The right choice depends on the job, the access and how your team prefers to work.
What thickness should kitchen carcasses be?
18mm board is the standard thickness used by every supplier in this list. Back panel thickness varies more, from 6mm on some wall units up to 18mm on some base units, so it is worth comparing.
Do trade kitchen cabinets come with doors?
Usually not. Cabinets, doors and worktops are typically ordered separately so you can choose the exact door style and worktop for each kitchen. Some suppliers stock all three, which allows everything to go on one order.
This article is a general guide based on the information each supplier published on its own website at the time of writing. Cabinet specifications, carcass colours, sizes, guarantees, lead times, delivery charges, credit terms and trade-account requirements can change, and some units are made to order while others depend on local stock. Please confirm specifications, availability and terms directly with each supplier before ordering kitchen cabinets for a project.
