Delivered on time but no phone call in advance to say when delivery would be. Should have ordered two bags but then noticed the ph value. Certainly composted down to a black mulch and it does break up the soil. Rather acidic possibly due to using so much leylandii?

Delivery was on time . Access is difficult in our narrow country lane but the driver was very efficient and friendly. The compost seems very good . My only complaint is exhaustion , having spread 60x40 litre bags over my borders in the last 3 days! Happy to recommend the product.

Having previously ordered the mushroom compost and been very satisfied with it, decided to order the organic green compost. Of good quality and was delivered on time by a very helpful delivery driver. Used the compost to enrich the soil around our shrubs in our borders. Would buy again and definitely recommend.

Again, good quality, and was delivered exactly on time by a very helpful delivery driver. The compost has been ideal for enriching the soil around our shrubs in beds and borders. Would definitely buy more and totally recommend,

Delivery a little delayed but carrier kept me informed and I was not really inconvenienced. Delivery driver helpful and cheerful and delivered both pallets exactly where needed. Compost good quality thus far but the proof will be in the growing. I already use the mushroom compost and find it brilliant. I have high expectations.

Delivery late as always. Rancid smell suggests it is fermenting. At least it wasn't totally waterlogged like the last load. Not good quality and not good value for money.

Excellent compost which we used as a mulch on herbaceous beds. Compost was still hot when it arrived and contained no bits of plastic. Prompt and efficient delivery

As usual, an excellent product from CPA and delivered with no fuss or bother. I've been buying CPA products fro the last year or so and have always been happy with the quality of soil improvers supplied.

I'm so impressed with this compost, it was genuinely a joy to shovel it into my planters. Very good quality, good amount of manure mixed in, smells wonderful, I'm sure I'll have some impressive veg by the end of summer. Have ordered another bag to have as spare, and free delivery was a bonus!

Compost delivery very quick. Organic green compost of good quality, with that nice characteristic smell of well composted material. I've already ordered 4x 1000L and it has been consistently good quality. Keep it up!

Compost delivered on time and with tracking information. Appeared to be good quality; good texture. The compost was compacted by it's own weight, so there is more than you think. I managed to get a good covering for a strip about 20m x 2m (40sqm). Looks good. According to my calculations, there isn't much of a cost saving for buying in bulk when compared with individual bags from garden centres. However, it saves a lot of plastic bags and is a good way to get the job done.

There were bits of plastic quite a few stones in it and it was still composting. I was expecting it to be fully composted. However the price is good for the product being cheap

Correction to earlier review it was 45 bags of 60ll each and not 65 bags, even so it was a mammoth weight.

My order of 65 bags of green compost arrived on one pallet - the driver left the delivery on the kerbside as it was physically impossible to move with a pump truck. In the process of trying to move it to a more secure location I broke my pump truck. The bags had to be hand balled off - I have not had a chance to check if all 65 are there yet but that it what I spending the rest of my morning doing. I shall be contacting CPA sales direct on this appalling health and safety issue, but as it is just me it might be a while before I am physically able to summon up the strength to pull together enough words without being too disrespectful....

Compost delivered a day late with no apparent explanation. No doubt the compost is good quality but 1 cubic metre yielded only 20 barrowloads - 4.50 per barrowload is exorbitantly expensive, however good the quality. The small discount for writing this feedback reduces the cost by only a fractional amount. As much as I would like to re-order the same amount, I couldn't justify the expense without a more generous discount. In summary, excellent quality product, very poor value for money.
