I've been very impressed with Ben and Yards. They were initially recommended by a friend and I asked for an opinion.
I have to admit that the initial quote was a lot more than I expected, but then I've never had my garden landscaped before so didn't really know what was the norm. What I will say is that if you want a quick superficial overlay of compost and a few plants then they're not for you. But what I hadn't really thought about until I saw their work was that they're not about a quick short-term pretty look, they're more about re-designing your garden for the long term. There was a lot of soil and rubbish removal - down to the bare bones of the old garden. After that there was soil, mulch, plants, turf, irrigation, borders and electrics (including lighting and watering systems), gravelling and a concrete edging. Much more involved and comprehensive than I expected, and left a beautiful result.
A nice touch was the hedge trimming and power washing of the drive that hadn't been included, and the unexpectedly thorough follow-up; Ben is obviously passionate about what he does and wants to make sure it works, rather than signing off once the job is done.
Happy to recommend, and would use again.
