Purchsed our floor and wall insulation from this company, they are very helpful and went through the options available to me. after searching about the total price was the best i had so i gave them the order. Deliervy was made in 2 days and everything was fine. I will use them again for the next part of my building project.

Yanislav Molkiva,

As a small building company we find that BMD will equal or beat our trade depot plus we get free delivery too !!, Also we can get everything in one order and being able to talk to an actual person rather than clicking on a website means we get the service we want. saves time and money whats not to like ? :-)

Clemency Bedford, Bedford Building Maintenance

Very happy with the service we received. Fantastic product at a fantastic price. Cant recommend Jason and the team highly enough. Ordered during Covid-19 when everything was slightly crazy and delayed and Jason called and said they had a lorry in our area so could deliver the very next day! Thank you guys for 5 star service, will be back in the future . All the best, Lacey. Travellers Finds Ltd

Lacey Griffiths, Travellers Finds Ltd

After days of trying to order some Rockwool from suppliers who never got back to me or quoted silly prices, my enquiry to BMD was answered in minutes politely and with clear knowledge of the products and delivery arranged on the phone all at a great price. Top marks for A1 service and product knowledge.
