Open Living was one of the last suppliers we discovered, but we were taken by their great range of windows, doors and lanterns as well as their sales team. Diane walked us through the many options but also listened to our preferences. Rather than steering us toward the most expensive option they were usually able to offer a choice on each aspect and the pricing was very transparent and competitive. Excellent quality ranges of windows, doors and lanterns. We opted for the Origin bi-fold doors, Origin aluminium windows and Atlas roof lights, all superb build quality/spec and great colour options.The installation team led by Danny and backed up in the office by the all-knowing Marsha and Linda were efficient, thorough and a pleasure to have on-site, coordinating well with our builder. Our neighbours also used Open Living before us and had a few issues at installation, but we believe these were mainly due to a supplier issue. All our windows, doors and roof lights went in as planned, well secured and sealed, with no damage.The only little point of feedback on their whole process is that the final quote and specification can spread across more than one document which did add a little uncertainty. This meant we had to double-check exactly what was coming. An all-inclusive final statement of all the options would be good. However, with a little bit of checking everything did come exactly as expected and we are extremely happy with the finished project.We would definitely recommend Open Living.

Open Living installed Origin bi-folding doors for our home. Their quality and service has been excellent throughout. Very trustworthy company. Right from the start, they provided good advice to help us select the right doors for our home; their quote was very competitive; their customer service was excellent throughout as they kept us updated on progress. The quality of the doors and the installation has been top-notch. Would highly recommend.

We purchased 1 set of bifold and 1 set of French patio doors, both Origin. Sales approach and customer service was excellent. Fitting and installation also excellent. Can't fault the product, either. Would have been 5 stars if it wasn't for an issue we had around the height of the threshold, which turned out to be much higher than we wanted/were expecting. This issue was resolved in a satisfactory way after discussion. Would definitely recommend, but my advice is to make sure the threshold height for patio doors is agreed at the survey and written on the paperwork before parting with any money.

Lovely people to do business with, we bought some BiFold doors and a window from OpenLiving. We did have a couple of minor teething issues once fitted but these were dealt with quickly and without fuss. Recommended!

I looked into a number of companies before deciding on Open Living in Letchworth for our bifold doors. I wanted the bifolds to be from a manufacturer that was very regarded, and Origin (though Open Living can also supply from Schuco and some other suppliers) certainly fall in that camp. I also liked the fact that Open Living were close to home, which made repeated visits to their showroom easy to make. Throughout the process, Linda and Marsha were professional and courteous and I would thoroughly recommend anyone who is looking to get bifolds to put OpenLiving Ltd on their shortlist.

So far I have ordered 12.5m sliding doors, 1 set of aluminium bi-folds and 5 windows from Open Living. The fitters are all great guys, and they take time to do a good job.The service and the products supplied have been excellent. I will be ordering more windows and do not hesitate to recommend them.

Had some OW80 windows that were fitted some time ago (by other installers, who had lost the cill caps).Marsha kindly helped me get some replacement items from Origin despite there being no financial incentive for open living to do so.Assistance has been very much appreciated and would highly recommend.

Had a great experience with Open Living. We had a 6m run of Origin bi-fold doors, an Atlas sky light some upvc windows installed. Customer Service and communication was good throughout, the installation guys did a good job and their technical guy was helpful with determining levels so we could achieve a level and flush threshold on the door. On top of this they were by far the lowest priced installer we found for the Origin doors which we had quoted by another three suppliers. Would recommend to others and will use again.

We weren't quite sure what bi-folding doors would be best but all the options were clearly and concisely laid out before us and some great solutions suggested to the issues we hadn't been able to work out on our own or with our builder. The showroom has lots of choice, brilliantly set out. We decided that Open Living would install our doors and they came and did a wonderful job.Looking forward to the spring to really get our new "open living" lifestyle underway!!
