Our marketplace

Glevum is very proud of the fact that it has been improving peoples’ homes for over 30 years. We believe one of the key contributors to our success has been our drive to ensure that we are honest, open and ethical in everything we do. We embrace the Marketplace aspects of Corporate Social Responsibility in the following ways:

Installation standards

We endeavour to ensure that each and every installation is done to the highest possible standards, by doing every job as we would want it done in our own home. We regularly send out post installation questionnaires to gauge how we have performed and monitor these results closely.

Our suppliers

We greatly value the role that our suppliers play in our continued success and look to develop mutually beneficial long term relationships. We also look to use suppliers local to our Head Office in Gloucester, wherever possible and have regard to their ethical and environmental performance.


Our Window and Door Showroom and Conservatory Village are accessible to all, including those with disabilities or special needs.

Health & Safety

We recognise the responsibility we have to our customers to operate a healthy and safe working environment for our customers, employees, visitors and contractors. We adhere to industry best practice in this regard and conform to all relevant standards.

Communicating with our customers

We are committed to honesty and transparency in our communication with customers and we adhere to industry best-practice in advertising and other marketing activity.

Satisfied Customers

"I am very happy from start to finish with Glevum and would not consider going anywhere else for windows and doors and I would highly recommend."

K Turnbull (Cheltenham) - Jan'22

"Very professional, efficient and friendly from start to finish. Product is top quality. Installers were superb and went above and beyond what I expected. Very happy with the end result and cannot believe the difference in respect of reduced noise inside the house and insulation properties. This is the 2nd house that I have used Glevum on and would have no hesitation in using again in future.!"

I Davies (Yorkley) - Dec'21

"I have been delighted with all aspects of Glevum Windows. They were tremendously helpful in helping and advising me on choosing the best style of window to suit my old property. The appointment to fit the windows and door was prompt. The installers, Danny and Damion were exceptional. They were quiet, very very tidy, I no mess to clear up, and so pleasant. Glevum were so professional from the start, and I would recommend always. Thank you!"

S Rees (Awre) - Nov'21

"Friendly, professional, helpful, they didn’t try to sell me stuff I didn’t need. The installers were lovely, respectful, friendly, cleared up after themselves, and were a pleasure to have here. Would definitely recommend them although they could do with some singing lessons!!!"
