We ordered building supplies including plasterboard, insulation, and chipboard sheets, and the service from MKM Wigan was absolutely brilliant. Delivery was prompt and completely hassle-free.

The driver was very friendly and took great care to ensure everything was delivered safely and placed properly at the property. Nothing was too much trouble, and I couldn’t thank him enough.

Prices are spot on, delivery is reliable, and the drivers are polite, professional, and genuinely helpful. I can highly recommend MKM and the Wigan depot, excellent service all round.

No refund materialised…

These guys charged me for a boiler which they didn't have in stock. While they called me to apologise, and promised me a refund, it's a month ago and I have received no refund.

Excellent customer service

Yesterday I contacted MKM, Perth and spoke to Claire Bright to get advice on a replacement part for our kitchen taps. Claire researched it for me and emailed me back with all the information I needed as I was unsure what to get. Even although MKM did not sell the part or made any business from my query, Claire still went out of her way to help me and went above and beyond what I expected. This was very good customer service and an experience that encourages me to go back to them in the future. If you are looking for a kitchen or even parts then MKM is worth visiting for good customer experience.

Treated T&G matchboard - avoid due to quality

Treated T&G matchboard - don’t bother! Ordered lengths of their 19x125 treated matchboard for an outside structure. Only part of the quantity was delivered before Christmas and this was of a good quality. The remainder of the order that was delivered after Christmas and is nothing short of diabolical - whoever MKM sourced this from has no idea of quality control. All the lengths were soaking, the finish was rough and the face of the boards looked awful. In addition the dimensions varied signifcantly from the first batch I received - yes i appreciate it is wood and wood expands and contracts but the same vertical volume of boards has given me a 60mm difference and it looks awful (I had no options but to install as I need to make the structure watertite). Add on top of this all boards were either concave or convex to a degree that some split when trying to get them to lock together and sit flush and all I can say is look elsewhere for this product if you want a reasonable quality.

Digger Dumper Service Bumper

Hired a digger and a dumper from MKM Blackpool. Great bits of kit and did the job nicely. Drop off and pick up were done around my requirements which freed up space on site. Lads at the shop always super helpful with any thing and the delivery team are obliging too. Great relationship with this firm.

Absolutely awful company

Absolutely awful company, the woman we dealt with was incredibly unhelpful and has no interest in supporting their customers to get a good end result. I would strongly advise avoiding this company and choosing an alternative.

Never again

First time I have bought from MKM ( Norfolk)and I will not be using them again or recommending them.l ordered a square head shower and received a round head, when I asked for the correct shower head I was told it would cost me £90 to correct their mistake. I ordered a right handed sink and received a left handed sink ( this they did replace) and there were items not delivered with the delivery (we had to go out and get from Screwfix so the electrician could complete the job) but the items were recorded on the delivery note. For a national company I expect better service.

MKM Builders Merchant MALTON - SUPERB BATHROOM PRODUCTS , ALL AT GREAT PRICES , AND FIRST CLASS SERVICE.

We have just about finished a full bathroom & cloakroom renovation . All the materials were purchased from MKM Builders Merchant, MALTON, North Yorkshire. We received a first class service from Joah Horne in the bathroom dept. Nothing was too much trouble for Joah, being very patient as we changed product specs on several occasions. The quality of the all the materials we purchased from MKM is absolutely excellent , and all supplied at very competitive prices. Would highly recommend MKM Malton

Jade at Longbenton Mkm

Jade at Longbenton, Newcastle upon Tyne has been fantastic. Ordered my kitchen through her and from start to finish has been friendly, helpful and patient and really happy with the quality overall. Few issues but replacements sent within days. Highly recommended to all.

Crap customer service

Ordered on line on Friday 28/11 and was contacted promptly and delivery was confirmed for a. m. following Monday. 14:30 on Monday called to ask when I can expect my delivery, was told that my order was not picked. Promised an AM delivery on the Tuesday, guess what 12:00 passed and no delivery! Called and cancelled the order. Got a call back to transact the refund with apologies for the poor service and they hoped that I would use them in the future, ( you’re ******* joking). Called Travis Perkins immediately and had the items 2 hours later and cheaper. And no I’m not promoting TP

Hired a Dragon Concrete Crusher from…

Hired a Dragon Concrete Crusher from the North Walsham depot this weekend, fantastic piece of kit recycled concrete waste into useable crush materials. Great advice from the branch, the driver demonstrated the product, including key safety features, no question was too much!

Equipment was low hours and in excellent condition, not the cheapest tool to hire but overall saved money by recycling waste into usable materials that would have cost more to remove and then buy in from merchant.

Well done MKM and staff at North Walsham hire desk.

They are quite good with supplies and pricing . But countless times stop them from sending advertising text but they don’t stop. Beware before you give them your information. Once they have your number in their system then you can’t stop them

Two orders in a row and both were unreal. First time I ordered at 11 and it was delivered by 1. Today I called at 11:30 and the new load was on my drive by 12:20. Less than an hour.
MKM’s service is consistently rapid, reliable, and spot-on every time. Can’t fault them — absolute top-tier supplier.

Watch out for their terrible drivers

Would be extremely careful around their drivers/ lorries. One hit my car back in March, manager at the Honiton branch was not a pleasant man & even laughed in my face & denied the incident had happened despite admitting the driver had previous "accidents" & there being a witness + significant damage to my car. Claimed there conveniently wasn't any cameras/ dash cam on that particular lorry (but others do!) & still won't accept liability 8 months later. Have also spoken with someone else local to me who had a family member who's car was also hit by an MKM lorry.

As a disabled person I am able to buy certain items VAT free. I am converting my bathroom to be wheelchair friendly and have had no problems obtaining VAT free items for this. MKM have refused saying that they won’t do this and I should reclaim the money from the VAT people, this is not allowed as I pointed out to them. Another well known company Topp Tiles has said there is no problem, and if I provide the relevant form they will happily refund theVAT.
Very poor from MKM making no effort to help the disabled.
