Gerard was a pleasure to deal with. His knowledge and advice was exceptional. We wanted to replace porcelain floor tiles in our kitchen, for Amtico flooring. We received two quotes from Amtico Premium Suppliers (to ensure a quality result, John Lewis and Higherground). John Lewis were about 24% more expensive than Higherground (like for like).
Another local company estimated the price would START at a figure around 35% higher than Higherground (depending on our Amtico floor choice), so we discounted them. The end result is great, and Joe, who installed the new flooring was excellent. We are delighted with our new kitchen floor.

We are very pleased to have found the team at Higherground and are delighted with our stair and landing runner.
Gerard is incredibly helpful - his advice and product knowledge is invaluable - as well as having a good eye for design.
Ben fitted our runner - his skill and experience is exceptional and the finished product looks amazing.
Thank you for a great job!

I found a very lovely rug with Higherground and even better it was in the 20% off sale section. Delivery was prompt and thanks goes to Darren for assisting with the dates. The product is a quality item and I'm delighted with it, and Higherground

I have used Higher Ground for flooring- carpets, stair runner, LVT and wood floor restoration for two houses, spread over a period of nearly 10 years. Each time, they have been very responsive and a pleasure to deal with, their product has been extremely high quality but well priced and the fitters have been very professional, returning to make sure everything was perfect. I highly recommend.

After shopping around for a number of options, Higherground were my preferred choice because of the options available and the effort and detail put into the process. Gerard and his team were exceptional throughout, from the quote through to the fitting and after-care phase. Really impressed and thoroughly recommended.

Have used Higher Ground for carpets in our last two homes and been extremely satisfied. A very well stocked showroom with various prices that will suit everyone. Staff and management always on hand to help and give advice. Had all our carpets and stair runner laid by very professional fitters. Would not hesitate to use again and to recommend!

First class service! Gerard was highly efficient in both the initial consultation and the planning of the project.
The estimate, fitting information and invoices were very clear and he was able to source the perfect materials and provide a range of samples to enable us to achieve the look we wanted.
Perhaps best of all he found a highly-skilled fitter to lay the difficult sisal we chose and the end-result is superb.
Would definitely recommend for any carpet/flooring/sisal needs.

Can't recommend this company enough. Brilliant team - Gerard and his show room staff were so helpful in helping me find the right carpet for my home. The install team were fantastic and worked around our renovation schedule which wasn't straight forward but it didn't phase them! They were so quick and efficient, I love the result and still get that comforting feeling when I step on the fresh carpet with bare feet 6 months later! First class product and first class team! Thank you.

Higherground have been our flooring company of choice for our last three projects and look forward to working with them again. Each time we have found their showroom staff and team of fitters to be highly knowledgeable and professional.
This company knows how to deliver high quality goods and workmanship with excellent customer service.

We initially become aware of Higher Ground as a referral and have been really impressed with the range, professionalism and service when choosing our carpets, all the way from ordering to delivery and installation. The showroom is well worth a visit if you're local, with a huge range on display providing much needed inspiration.
The fitters were great and overcome an issue with a slight challenge we had with differing floor heights, and were able to adjust a door allowing for the carpet and threshold to be fitted correctly. We have had two bedroom carpets from Higher Ground and will definitely be returning to them, once we are ready with our next project.. Can't recommend them highly enough!

I had been admiring a beautiful Hummingbird rug on the Higherground website for months, but hadn't got around to ordering. Finally decided to go for it early in December, and received the rug in time for Christmas. The rug is stunning and fits in with my decor completely, and the service was impeccable. I would highly recommend Higherground to anyone.
