Knall Avis 

Excellent customer service and the quality of the blinds is top notch. I would say they are also very affordable for the quality too.

Excellent,good service,quality staff

I placed several separate orders for venetian blinds. The products are great, but the customer experience can be improved.
1) On every occasion they have either sent a text late in the evening for a delivery the next day (no time indication) or they just phoned saying they will deliver in 1/2hr. No previous communication that they would deliver that day.
2) The fixtures are quite soft material and can easily bend and then don't work anymore. This happens easily, especially if you are new to the system and the blinds quite large and heavy. I asked for some spare replacement fixtures, and they wanted to charge £5 for each + £25 delivery costs. This is £45 for 4 replacement fixtures. For a company that is not the cheapest, I would have expected this to be just part of the delivery, no fuss. I ended up just buying on Amazon for £4.10 (4 fixtures). I can recommend for the product, but not for the experience.

Just received my order could not be more happy brilliant product well made and very easy to install.. only thing I would love is a customer service number but the mobile number that I found online the guy was polite and when I was chasing up my order he got back to me straight away… will definitely use again brilliant!!!

Quality 100% second time when we buying from them and probably not last
Thank you :))

Excellent product, well-made and easy to install would use again,

Can't recommend these Knall Roller Shutters enough. Absolutely love them and great quality 👍🙂

We ordered two roller shutters on 2nd Feb and they were delivered on 2nd March, much sooner than expected 🙂 The large one 2.8m wide x 2.5m high to fit externally over a patio door - dropping to the floor and a smaller 1.9m x 1.4m fitting externally over a window, this one dropping to the windowsill.

The roller shutters are fabulous 👍 Well made, all aluminium and a great anthracite colour. We ordered them both with 5 channel remote controls (for the Aluprof RM45 40 motors), which can control each roller shutter independently or one controller can operate them both together. Really pleased 🙂

We had a couple of questions before ordering, so emailed Kamila who was very helpful - although I think their preferred communication method is email.

Just a note to help everyone: You need to read and re-read the online measuring instructions carefully before ordering. This is the most important bit 🤞 The dimensions are the overall sizes, including the width of the side rails and the size of the overhead box (which varies with the drop) - hence read & re-read everything, measure and re-measure...

I had to take into account the patio door sill, door stop and door handle, so needed to add a wooden frame to pack the roller shutters out from the external wall by 50mm so ordered the patio roller shutters with "angular guides" to cover the majority of the wooden frame sides (externally). I painted the wooden frame in Bedec multi surface paint satin anthracite paint (Toolstation) which matched the roller shutter colour exactly. The smaller window just needed the "straight guides", as this shutter fitted directly onto the wall.

Overall, we love the roller shutters, they are great quality and a brilliant finish. The house feels so much more secure with them too. Highly recommend Knall !!! It's a shame we can't attach photos...

I placed an order with KNALL several weeks ago I found that direct communication with them was non existent by telephone which would in the future prevent me dealing with them again at this time . The lady I was emailing appeared helpful but when I reported a shortfall in my ordered I was not understood and as all the items are not identified appropriately it was somewhat difficult to describe. It is a plastic handle that is attached to the tape for moving the shutter up and down manually. Kamila said they did not do this part any more and yet it is shown as a fundamental part f the assembly instructions. Fitment instructions are not detailed enough. { It would seem that they want to do the job} for the home DIY expert. My part is still missing, I will assemble myself, But I will not use them again

After a long wait, I can say your product was of a high stander and I would use your company again!

Product is good
Communication with customers could be better

Really good quality blind at a great price - communication was great throughout the whole process - Thoroughly recommend

Terrible service.
Ordered some “free” samples. Was charged £5 for delivery. They arrived 6 weeks later with just a second class stamp and a further £1.50 postage needing to be paid..
Wrote to customer services to complain but heard nothing back.
Avoid.

Impressed with website and product but courier absolutely diabolical. No communication and unable to contact in any shape or form. Knall customer services of no help only contactable by email and no attempt by them to speed up delivery. Courier attempted delivery to a business address at 4.30pm on a Sunday afternoon and I didn’t see the shutter until 15 days later. Knall implies they use international couriers like DPD, TNT and UPS of which they clearly didn’t use with our delivery.

Gave Knall an ultimatum to deliver by the weekend two weeks later after first delivery attempt or would demand a refund. No response from customer services just a phone call from courier who claimed he would deliver over weekend but needless to say didn’t arrive. Turned up on Monday!

Won’t be using Knall again as missed a deadline to have product fitted purely down to courier service. Can’t put up with this sort of service.

Product good, time manufacturing no so, the only gripe I had was the instructions for the tape pulley system was no where near what you had to do to make it workable, the sizing and overall finish of the components spot on, the communication was on point also

I was very impressed with the roller blind and it was excellent value. In every step of the way in dealing with the company has been faultless. The blind was easy to install and the installation notes were very useful.
The product was of good quality and at a very competitive price - most impressed.

Really good website to help choose the right options. Good support and product delivered exactly as expected.

Very happy with doors ordered was exactly what I wanted. Delivered early. Easy to fit.

Delivery takes a bit of time. But all products are high quality.

We ordered some roller shutters which last week arrived in a van. The online ordering system is very easy to use and if you read their instructions they tell you exactly how to measure (ie that the sizes you put in have to include the guides and the top box). The delivery was quicker than promised. The shutters seem of very good quality and everything was correct with our order and they have now been installed and look great! Will definitely use again when needed.
