Please do not touch James-Oliver Conservatories (based in Lincoln) with a 10ft barge pole, their customer service and after sales support is absolutely abysmal. They are by far the worst company I have ever had to deal with, they fit doors and windows knowing that parts are missing or haven’t been supplied as part of the installation, only to then take months of haggling and chasing trying to get your newly installed doors and windows finished. If I had been informed before the installation took place that key parts to complete the works were missing, I would never have allowed them to proceed with the install. I now have poor fitting shoddy doors and windows that allow the draft to come in and still no date set for when this is going to be rectified. They only told me parts were missing 30 mins before the job was supposed to be complete, leaving me no choice but to put up with this sub-par fitting service. After months of e-mails and telephone calls I still have no idea when the works will be finished. Do NOT use this company, they are a bunch of con-artists.
