What our customers say about us

Second time I have used Monnow, completely seamless transaction from first contact to delivery of our latest unit, delivered on time at the agreed price. I was so confident I bought the unit unseen on Andy’s description which was 100% accurate, highly recommended!
fantastic service. we told Andy the exact size we were looking for which was a bit of an ask as it’s a rare size and he got one within a few weeks! all painted in preferred colour and delivered nicely, thank you team.
Andrew is a great guy to deal with with excellent service, price, and knowledge of stock required. Highly recommended
Great container, delivered as agreed. Rob’s communication was faultless. Very happy & would recommend.
Fab service & advice, insulated & painted, with quick delivery, thank you.
We needed a container in a hurry for fodder storage and Rob at Monnow provided excellent personal service. Our container was sourced and delivered within a week and the delivery was super-efficient. Couldn’t recommend them higher as a company, thank you.
I recently bought a 24x10ft refurbished container office from Monnow Site Services and have no hesitation in recommending them. Rob Matthews dealt with all my questions promptly and professionally and he followed up as promised. Delivery was 1 week after ordering and payment. Rob wants his customers to be happy and he shows this with his communication style and approach. A great new business!

Good job Andrew, it has made a big difference to the Building, thanks very much.

Rob and his team are very approachable and understand the customers’ requirements. Over the last month our company have had 2 containers from them – a 20x8ft store and a 24×8 canteen/drying room of which was altered to suit our requirements. We shopped around and found their containers to be competitively priced with reasonable costs for alterations as well as delivery. Will certainly deal with again.

Big shout out to Andrew Brace of Monnow Site Services for supplying our replacement container.

I bought a 21ft welfare container today and I must say Rob has been great and very accommodating from start to finish. So nice to deal with such genuine guys. 100% recommended from us at M4 Lifting services! Wish you the very best guys!
Hi Andrew, the container was delivered safely. Many thanks, really pleased with it. Hope to put more business your way in the future.
A genuine company with excellent customer service – highly recommend. In a time where there are many ‘scams,’ it’s great to find somewhere that responds to all requests in a timely fashion, welcomes viewings and delivers on its promise. Rob made the process effortless – thank you ☺️
Just wanted to say thanks! Very happy with the cabin and service. Will be in touch once my spending cap has been lifted.
Depending on what it is for, If you have space available then maybe look at shipping containers as they are great for storage. Robert Matthews in Raglan supplies them, can kit them out to suit needs and deliver them. A friend of mine just had one and so can highly recommend him.
So pleased we went with these guys. Totally professional. Great to visit the container prior to purchase, they installed a door to the highest standard, painted. Delivered exactly when promised. Not a simple delivery location, but got the job done exactly how we wanted it. Good price, excellent service. Highly recommend Andrew and the team.
Great company to deal with. Andrew helped us out with finding a fantastic 2nd hand office container, fully refurbished with electrics, heaters, insulation, lighting and lockable doors, all with Hi-ab delivery for a fair price, and at quite short notice. Was able to provide photos and videos, and was very good with communicating with us throughout. Super pleased with the result, would recommend!
I have just had a delivery from Monnow Site Services, a superb 12×8 Site office grey cabin. Forget searching for the cheapest, and wasting time on Cabin’s that don’t exist?, Rob and his team offer a truly great product and service. Even Bengie, the delivery driver was easy going and very professional in executing the placement of our cabin, over a wall and into position. Forget the scammers, use Monnow Site services for a truly honest deal. Great personnel, nothing to much trouble, and great service, will use them again when we want this shifting to our next home!
Excellent products and services. We spent ages vetting companies and visiting sites before ordering an office/toilet unit and 4 storage containers. We heard so many horror stories and say some really dodgy set ups. Monnow site services was happy for us to go to their site to see them in action we saw the base unit before work started and cannot believe the transformation. We would highly recommend this company. If you are looking around, this is the one to go to. I know that some reviews are, or seem to be too good to be true, but in this case its not. If you want to come and see our units in real life, just ask Andrew for contact details we are in Bridgend.
