Lowest online price, including delivery, that I could find in my area. Delivery took 2 weeks which was fine by me. Helpful and friendly driver delivered, all my items were undamaged and good quality.... See more

Amazing service and great prices. Ordered timber for my raised beds, arrived the next day with a super friendly delivery driver. Local delivery was free and they were £30 cheaper than a more local timber yard. Highly recommend them ,shall be using MKM for everything in future! THANK YOU TEAM MKM!

I had a disappointing experience with MKM’s kitchen design and delivery service at Workington. Two different people poorly managed the design process, which led to miscommunication and errors. The wrong wall cupboard door was delivered twice, which caused significant delays and inconvenience.
There were also discrepancies in the design, resulting in several retrofits and necessary changes. Delivery times were much longer than expected, and the project took 34 days for the joiner to almost complete—yet 5% of the work was left unfinished, which I had to complete myself.
Although MKM does not officially recommend joiners, what concerns me most is that MKM staff were aware that the joiner I used had a mediocre reputation and previous complaints from other customers, but they did not warn me or suggest alternative options. The joiner's workmanship was poor; even basic tasks such as cutting the MDF panel straight were poorly done. I agree that selecting a mediocre joiner is on me, but it was frustrating that you knew the joiner's background and didn't warn me.
Overall, my experience was frustrating and disappointing. I would advise others to be cautious and ensure clear communication and transparency—especially regarding final design before ordering—if considering MKM (Workington) for kitchen projects.

MKM Bury. I placed an online order on Sunday 19th. I phoned Tuesday 21st to chase it up. Not in stock, they will have to order it in. Phoned Saturday 25th April, advised that they have forgotten to order it! I asked them to cancel the order and refund me. They advised it takes 3-5 working days to get my refund to me !!! NOT GOOD ENOUGH
Asked for a quote for a complete bathroom refurbishment, a week later still haven't heard from them. Very disappointing.

I have been dealing with the Southport branch, which is only a couple of miles away from where I live, for a few years now. They are usually cheaper than the competition and normally deliver the next working day, free of charge, regardless of the value of the order. The quality of the products is excellent. I have an account and usually order on-line. First thing the next morning, I invariably receive a phone call from Paul, to arrange delivery, usually within 24 hours. If you pushed me for a negative, it would be the slightly limited range of products and the opening hours; I am sometimes frustrated at having to resort to paying "over the odds" at B&Q or Wickes.
What a fabulous experience meeting Charlotte, who was extremely helpful, friendly and very knowledgeable about the Symphony kitchen range. Even though we were only enquiring about purchasing a couple of cupboards nothing was too much trouble, we received a quote within the hour and would like to thank Charlotte for her super customer service and the time she spent with us.

I gave this company the chance to fix an issue with glass in the topsoil they delivered, making it clear it’s being used in a garden with my toddler and dog.
They collected the bags, said they’d found more glass, and said they would deliver topsoil from a new supplier. The delivery wasn’t communicated properly, and when it did arrive, it was the same contaminated soil with more shards of glass.
A full refund was issued but we’re now having to go through the soil in our garden by hand and are still finding large pieces of glass. This is completely unacceptable.

I have used Mkm Llandudno junction without question for 19 years and never questioned an 2 way respect for and from the business. However not respecting a customers name and failure to do a refund which was 100% due. The senior management who were in the ‘loop’ shirked to contact me to put things right or to explain the happenings. A complete system failure.
There are 2 results here, treat Mkm with the respect they deserve and don’t expect a refund when due.
I had to seek help from my bank to temporarily retrieve my monies not from Mkm Llandudno junction

Waited in all day for the delivery and when it got to 4.30 called them asking where my delivery was only to be told that they had a problem with one of their lorries,yet never bothered calling me to tell me this even when they ask for your phone number when ordering,really disappointed with the customer service,they apologised but that doesn’t really make a difference when you’ve wasted a whole day waiting in for them.

The service provided by the team was brilliant (with a special shout out to Tracy the Driver), I ordered two bulk bags of gravel and cannot find fault. Thank you again xx

The Staff at MKM it has to be said, know what Customer Service is, finding what I wanted was made so much easier, by the friendly and helpful Staff at the Huntingdon Road Branch, in fact, the Staff at all three Dumfries Branches are a credit to MKM
Can not fault this company one bit, I ordered in the morning and by the afternoon I had delivery, Jason called me to let me know when the delivery would be and he was very polite, I would definitely order from this company again should I need to .. thanks guys :)

MKM Woodbourn Rd Sheffield
Ordered grey slate on the Monday for delivery Thursday. We rang them Wednesday for delivery slot, was told pm.
Waited and waited, rang them at 3.45, said they'd had trouble with their deliveries...so wouldn't get it.
I wonder at what point they would have informed us they weren't delivering??
Requested a refund which we did receive
Time off work for this delivery 😡😡
Poor service
Ordered a large bag of sand from the Bangor branch. It wasn't expensive and the office were quick to inform me of a delivery date, which was only a couple of days later. It arrived promptly. Driver was friendly anf helpful and dropped the bag right where we needed it.
Excellent service!

I had a very poor experience in Chichester branch. I ordered some oak sleepers in September 2025 which were never delivered even though they had been paid for. They said they had problems with their suppliers but their website said they were still available. The price of the sleepers also increased. Originally said they would honour the lower price but, they then changed their mind. I challenged this and they said their director would phone me but I was never phoned back. I had to do all the chasing. After many phone calls, and no call back ever received from them, they decided they would honour the original price after all and that they were working on it and I would be contacted shortly. Of course, they didn’t get back to me and after another phone call, they then said they still had issues with their suppliers. Six months had passed since the original order, and they couldn’t be bothered to update me. They just weren’t interested. They were not true to their word and I finally lost all trust in them and got a refund, whilst for six months my money could well have been earning them interest their the MKM bank account throughout.
Ordered a shower screen after sending an email enquiry and received a response almost immediately with a delivered price. They weren’t the cheapest option, but they were certainly competitive. Although the shower screen wasn’t in stock with the manufacturer at the time, they advised they could source one by a specific date.
Communication throughout was excellent. Payment was straightforward, and they kept me updated on progress. Then, two weeks before the expected date, I received a call to say the screen was actually available and could be delivered earlier than planned - a really nice surprise.
It’s great service like that which you don’t always see these days. I can’t recommend them highly enough - especially Simon, who handled everything from start to finish. A real credit to the team. Well done.

We recently did a full kitchen refurb, absolutely over the moon. The whole process start to finish was great. Michelle the kitchen designer was friendly yet professional and had some great ideas, our space wasn’t the easiest to work with taking into account what I wanted to fit in and my expectations. I think it’s safe to say, she did it! Can’t thank her enough. The quality of the kitchen was even better than I expected, even the kitchen fitter was impressed. Love love love it!

Another great purchase from this company. Helpful friendly people and great service again. Highly recommended 👌
Used MKM Chelmsford since the day they opened. Over all I’ve had a great relationship with them over the years. But what stands out is being able to message Bear after hours to sort something out. And it is never a problem. Service above and beyond.
