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 asked 5 company’s for quotes to fit a new back door and supply and fit a conservatory, Glevum were the only company to provide a quote. They have turned up on every occasion when they said they would and communicated well to confirm times. A very professional service throughout."

R Wilks (Cheltenham) - Apr'22

"Each aspect of Glevum’s service was very professional, from start to finish. From the initial visit to provide a quotation, followed by the surveyor, and finally the fitter. Like most people I was a little worried about the disruption of installation, but the fitter worked quietly and efficiently, problem solving along the way, tidied up at the end, and I am extremely pleased with the end result. Would highly recommend."

J Basden (Coleford) - Mar'22

"Very Accommodating initial contact in November and Glevum agreed to delay installation until the New Year. Good advice, very expertly measured up, even the large windows fitted within a few mm. The installation team worked through one of the gales and only returned for a couple of hours over the three days allocated to finish outside trim on four windows (out of 12). We are very pleased with the outcome..."

A Crowther (Cheltenham) - Feb'22

"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."
