Guardian Certified Installers

When you begin the process of selecting your Guardian Warm Roof, a crucial step is deciding on who will be installing your new warm roof. 

They need to be experienced in this type of construction, communicative, efficient and reliable.

At Guardian Building Systems, we have a network of companies across the UK who are part of our registered Guardian Certified Installer scheme. 

Each one of our Certified Installers are registered to install this unique product onto your conservatory and have been expertly trained by us. 

We completely trust them to provide the best service possible, for your peace of mind.

Selection and training

We pride ourselves on the consistency and reliability of our certified networks, which is why, to become part of the scheme, installers must:

• Have a 10-year workmanship guarantee in place
• Offer an insurance backed guarantee
• Pass a credit check
• Have a minimum of 1 years trading
• Have a minimum public liability insurance cover of £1 million 

All our Certified Installers must also go through annual training to ensure they are the fully qualified to keep installing Guardian Warm Roofs. 

The Process

Allocating you a local Certified Installer: Once you request a quote from us, we will pass this on to your local Guardian Certified Installer.

We pride ourselves on prompt responses, so you can be sure your Certified Installer will be in touch within two working days to discuss what you need.
Planning permission LABC Certified Guardian Warm Roof Installers
Home and visit quote: Typically, and because our Certified Installers quote accurately the first time with no hidden costs, this then leads to a site visit.

Once your site has been properly surveyed, our Certified Installers will aim to provide you with a final quote within another two working days.

Once you have decided you are happy with the quotation, then the real work can begin.
Building Control Approval & Fabrication:  All of our Certified Installers are able to access and partner with LABC Authority Scheme allowing for swift and no hassle building control approval and compliance.

Final precise measurements and requirements of your conservatory roof are taken and prepared ready for fabrication. All our Guardian Warm Roof products are manufactured in the UK before being promptly delivered to your site for installation.
Installation: Because of our Guardian seal of approval, you can be assured that this installation will be undertaken by a trained and qualified professional. These additional assurances will give you peace of mind for years to come.

Thanks to the prefabrication of our system and the experience of our installers, the installation process itself usually takes as little as 2-3 days, so you can be enjoying your space before you know it.

Although this timeframe may vary depending on the size of your conservatory and whether any additional structural work is needed, you can rest assured that we will carry out the installation efficiently and with as little disruption to your home as possible.


Working with our network of Certified Installers means guaranteeing a smooth installation, but we promise immediate resolutions when things aren’t going as they should.

Independently tested by the Buidling Research Establishment
System approved by Hertford Building Control
Building control compliant with LABC


In nearly all instances, a solid roof replacement on your conservatory does not require planning permission, but it does require local authority building control approval.

The Guardian Warm Roof is an approved system by Hertford Building Control which allows any Certified Installer to access and partner with the LABC (Local Authority Building Control) Authority Scheme to swiftly process all necessary building control requirements for your replacement roof.

In short, all of the stress and hassle of building control approval will be taken out of your hands, and you will have the peace of mind that your replacement roof is not only compliant but can also be completed comparatively faster than other solid roof conversions who must take additional time seeking the necessary LABC approval.
