Went to our local MKM for a new kitchen, sat and worked with them over multiple visits on the design and they recommended a local joiner to install.
We placed an order but were asked by MKM to pay the joiner for the whole kitchen, not them. Didn't really think anything of it but it became very important later.
We had multiple MKM issues with the wrong doors and worktops being delivered that delayed our kitchen by two months.
In the end, we were so frustrated at having no working kitchen we complained to MKM. Their response to us was "go away because you are not our customer, the joiner is". We were utterly shocked at how we could spend five figures on a kitchen and be treated like this, we'd been forced to order through the joiner by MKM, we hadn't chosen to. A new kitchen represented a major investment in our home and it should have been a wonderful experience. MKM made us miserable. Won't be giving MKM a penny again.
Where do I start, went into MKM in Macclesfield to look at a new kitchen, after being recommended by a friend. Was dealt with by a staff member called Rob, Though he was very helpful in selling us a new kitchen, we just occurred one problem after another. Over four months down the line we was offered a paltry £400 discount ( which WE had to pay £380of that to the kitchen fitter and an electrician- due to faulty goods ) MKM just wanted to pass the blame on to the kitchen manufacturers ( but of course it’s not them ) So £20 up I thought I’d give an honest review of the treatment me and my wife, who MKM had in tears twice, from either wrong stuff being delivered, damaged good, faulty oven, incompetent, finding the delivery just left outside of the house in broad daylight with so much as a knock at the door or a ring of the bell.
I’ve gave MKM 1 star, if I could it would be a zero. So much more I could add to this list.
If I could offer any advice- AFFORD AT ALL COST.
You have been warned
I would like to give this company more than 5 stars from my husband and me, choosing the shower and cabinet, fixings, etc, quality was excellent as we are in our 70s, upgrading our bathroom, and the helpful advice from the 3 lovely ladies in the Carlisle store was just brillant. Delivery was excellent from Luke, who carried items up the 13 steps, so we wouldn't struggle was very helpful thankyou to all.PS would recommend this company brillant service.

I ordered a bulk bag delivery at a very competitive price from MKM Glasgow (also getting free delivery) and the whole process was great. Arranged a delivery day and put a delivery instruction on the order and once the loader arrived he was very friendly and literally dropped the bag exactly where I asked him to. A fantastic buying/delivery experience from start to finish. Would highly recommend using MKM.

I wouldn’t hesitate to recommend MKM Building Supplies. Paul, Martin, and the whole team are outstanding — nothing is ever too much trouble. They’re always friendly, helpful, and even went above and beyond to find me a plasterer when we were let down. Great prices, excellent service, and consistently efficient. I wouldn’t buy from anyone else!

Bought some “plastering” sand from them - dreadful stuff, more grit than “grit sand”! Washed 2 bags of it because I had to get the job done, & got a “brick’s” worth of grit/gravel out of it. Trading Standards should really take a look at it!

Ed, at the Trafford park site has been absolutely fantastic with his customer service. He followed up with two calls to ensure the tools hired were ok!
Genuinely the best customer service you can ask for. He went far beyond what other companies do by sourcing the equipment we needed. Fantastic , thankyou Ed

Impressed with prices and service from MKM Grantham.
Saved £20 on insulation boards compared to Wickes.
Free friendly delivery also included to Melton Mowbray.
Would recommend based on my experience.

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. An update on the delivery status (email, text or call) would have made it 5* but still very pleased overall.

MKM Leeds.
First time ordered from MKM Leeds. Main reason - free local delivery and they are only 2.5 miles away from me.
Couple of sheets of plasterboard and some loft boards.
Received and email saying they will aim to deliver Thursday or Friday. I tried to clarify, but was told they won't know the time till the morning of the delivery.
Thursday I receive a call from the driver saying that he is outside my property (while I am at work).
He offered to leave everything outside the property, which I was okay with. Luckily rain was not forecasted.
The only negative at this point is communication, which could be improved to avoid situations like this. I could've been at home to accept the delivery.

Whilst building our home on the Isle of Mull, we used MKM in Oban.
They where absolutely fantastic, priced matched when they could, we had no issues either deliveries, which were free, always super helpful. Understanding of our lack of knowledge, always advised us on the best products. We ended up only using MKM, they were absolutely brilliant.
Big shout out to Steven Bruce , Duncan and Stacey, thank you so much, we love our MKM house.
5☆.

I am currently working on a small single storey Extentioni cannot recommend MKM (Gloucester branch) enough
Ricky and his team cannot be more helpful, everything I need is available or if not is sourced for me in a very professional way. I will continue purchasing all my materials from MKM and would strongly recommend anyone looking for any type of building Materials to do the same

Ordered a small quantity of architrave wood from the Lladudno Junction branch late Sunday afternoon. Imagine my shock when a polite and courteous driver delivered right to my front door at 11.00am Monday morning! The wood was good, well selected and prepared, and well wrapped. Such good service is rare in this cruel day and age. WELL DONE MKM

I ordered a ton bag of top soil from MKM via their website, the process was flawless.
The product was delivered today 03/09/25 by Wayne (Grantham Branch) who called me to state he had arrived with his Hiab to deliver the soil. I must say Wayne was fantastic, he went out of his way to assist and dropped the soil over the wall which will save my poor back with hauling it from the driveway.
Nothing was too much of a problem, many thanks Wayne you are a credit to MKM.

I visit MKM to purchase some wood. I was helped by Cara Seymour who was exstremely helpful. She went out of her way to check on how much timber I needed against my measurements, nothing was too much trouble. The delivery was also free and yesterday they arrived first thing. Thank you I will be return.
