"I would 100% recommend Celestial. They were brilliant from start to finish. I contacted Celestial windows after being let down by another company. I spoke to Atif who was very helpful and managed to get my bathroom and cloak room windows measured, surveyed and installed within a very short timeline due to bathroom renovation. Atif was very understanding of my situation and managed to get everything done within a few days which allowed me to go ahead with the bathroom renovation. The installation guys did a brilliant job and left everything very clean and tidy. I would definitely use Celestial again and would highly recommend to other too."

"Have used Celestial on many occasions for both windows and doors. Top quality products and fitted to very high standards every time. Fitters have always been courteous, knowledgeable and helpful. Would highly recommend and definitely use again. Aftercare is amazing and a couple of small issues long after fitting have always been rectified efficiently and professionally"

"Avoid their installation service; good manufacturer...but: Both times I used this company I had to have 'remediation actions' take; in the 2025 contract these were detected and enforced by formal building control inspections as Celestial's management declared that their internal 'installation manager' lacked the skills to assess building work. Seriously, I requested - and got - the recording of the phone call via an SAR stating this. Their approach was so bad on the last job they couldn't/wouldn't complete as they 'ran out of money' (again, quoting from a phone call I have their record of), so I had have the contract finished at my own, extra, expense - and the hassle that went with it. Hence photos show Phase I of III - all that was delivered. Is poor to medium quality, if Building Control complient (i.e. 'minumum safe standard'): the blockwork is particularly shocking - who does blockwork like that and not called 'Clive'? - remember this is their second attempt as they took it down to 'remediate' (install) the insulation they missed underneth it the first time. Oh and the frist waste skip was on the pavement and over the street's fire/water hydrant; was removed when I pointed this out to the skip company directly and Celestial organised a replacement. The replacement was on my lawn for a month until I arranged for its removal directly - again - with the waste company.....who didn't know what size it was until I went out and measured it."

"They provided and fitted a front door for us. Amazing selection, really competitive prices and fantastic customer service. Fitting was outstanding and we are so happy with the door and the service. Brilliant company would highly recommend."
