Feedback
Great service, thank you
...j m budny
I was happy with the service. The mirror was well packed and arrived safely. The only quibble might be the delivery period. It took some time from order to receipt. Having said that, it did arrive on the day you said it would so it's a minor complaint
...Derek Cairns
Hi, I am pleased with the service. The delivery time could have been shorter. The goods Drayton Actuator are as expected. The goods work well. I am happy with the price. If necessary, I will use you again. Thank you. Ian Smith
...Ian Smith
Excellent communication so i could keep my customer upto date
...dan morgan
Materials ordered were delivered by local suppliers. However it took a week to arrive. Ordered other materials at the same time from another plumbing supplier, which arrived the next day. So materials ok but delivery poor. Would I use again, yes.
...Mr David Gordon
Received the parts in perfect condition. Although there was a delay, I was kept informed at every stage. Great service!
...Morag Dobbin
Very satisfactory. My only complaint, which is about your supplier rather than yourselves, is that they cut my 6m lengths of pipe in half to get them in their van. This means I will have to make extra joints that I had hoped to avoid. Not a disaster but a bit of a nuisance. Otherwise fine. Thank you.
...Denise Hammond
The service was very good 4star thanks.
...Darlington - BESC
Excellent service, kept informed from start to finish. Good prices and free delivery. Would definitely recommend and use again without hesitation.
...Mike Willcocks
Tub is fine and price is competitive. But when the final delivery date was updated, there was no email notification. That caught us out as no one was available to bring it into the property. So it was left outside until the evening. Driver was very helpful though and did his best to leave it on the private footpath.
