Celtic Sustainables Avis 

I really like this site and their products. Everthing we've bought so far has arrived promptly and has done what it says on the tin. Good prices and it all helps the environment. Thoroughly recommended.

Excellent all-round. Very competitive, good choice of products on their website. Delivered on schedule. Packaging good. Haven't opened the paint yet so hope it's in good condition on opening, but can't fault them, really. Would definitely use them again, especially as I am in Wales and so are they.

We've made two purchases over the past six months of Thermafleece Cosywool from Celtic Sustainables, both times the product arrived quickly and well packed. We plan to make further purchases in the future as our home project progresses.

Good communication prior to making the order. Goods arrived well within the delivery period. Very well packaged.
Paint was very easy to apply, excellent coverage and no nasty smell.

Unlike other suppliers of Thermafleece who only give options in multiple of 3 roll packs, Celtic Sustainables allow you to choose the exact amount of rolls which is more efficient.
They might be slightly beaten on a per roll price, but taking the above into consideration plus their postage costs, I found them to be the best deal for me.
Delivery was very prompt as well.
I can thoroughly recommend Celtic Sustainables!

What a fantastic product and super efficient firm to deal with!
The delivery on the items was absolutely excellent arriving in less than 48 hours from ordering time - had anticipated it being much longer!
The product is lovely to work with, did not detect any smell previously mentioned. Very soft and easy to fit although larger, sharp scissors are required for cutting. Only difficulty experienced was keeping dogs from claiming it for a bed whilst cutting to size!

A great company to deal with. Good value and prompt delivery and friendly staff. Would definitely recommend.

great that they sell wool insulation in smaller amounts than others. Fair pricing. Great comms and prompt delivery. Thank you

Easy to contact, helpful and responsive. Great choice of products.

Bought the sheepswool insulation roll, excellent product found it easy to work with, no irritation unlike fibreglass rolls. Good communication from certified. No problems

Quick delivery and service. Very pleased with wool insulation. Much more pleasant to use than ordinary insulation. Yep, it does smell, but once its covered by plaster board etc the smell goes.

Great products (wool based insulation & ecofan) delivered promptly

Ordered Earthborn paint again, we have had quite a bit over the last few years. Celtic are definitely the best supplier, the price and exceptionally quick delivery make them our only choice.

Ordered 16 packs of Thermafleece insulation from Celtic Sustainables, everything ran smoothly in the ordering process and updates given often. Arrived on time, well packaged on a pallet. Great product from a great company!

Quick delivery

Efficient service, product light and easy to install. You can actually 'rip' it into lengths with your hands. House seems noticeably warmer.

Excellent service and delivered in time scale, arrived in perfect condition 5 stars

Excellent service and product. Quick delivery, they even called me to say it would be a day later than expected due to stock levels. Product as described and easy to use. Would definitely recommend and use again.

Product was as described and arrived promptly.

Hi there. I would just like to tell you that recently we purchased...
Thermafleece cosywool sheeps wool insulation for our loft. It was a pleasure to fit. My son and I did it. And, we all agreed that the house felt warmer from the day we fitted it. A very good product! We used 75mm between joists and then used 18mm board on top.
And, supply was very efficient too. Thank you.
