Built On Solid Foundations.

Our Story


Fensurv was initially founded as a double-glazing & extension surveying company, otherwise known in the industry as "Fenestration Surveying", hence the name Fensurv. 

Fensurv has provided a surveying service to both big and small companies across the UK, Our service users lacked the necessary knowledge and skills to deliver a seamless home extension project. In our first 12 months of trading, we surveyed over £5 million in home extension projects across multiple companies. Our second year saw us double that figure to over £10 million in surveyed home extension and hup! projects and consultancy work by offering training to company designers/surveyors who had little to no knowledge of what they were designing or surveying. This should speak volumes as to our level of knowledge and respect within the extensions industry. 

How Important Is The Survey?

Because the hup! modular building system is manufactured like a giant jigsaw puzzle. It means that every single component must fit exactly; if it does not, then ouch... You can't adjust it by cutting it down or extending it as you would with a brick-built structure, which means your project will have to go on hold until replacement parts are delivered, not ideal if you're modifying an existing conservatory!.

Our dedication to perfecting the survey process for hup extensions is what sets us apart from ALL other companies. We have worked tirelessly trawling through the latest technical manuals to stay ahead of the curve on both today's and tomorrow's innovative industry products. Couple that with our in-depth knowledge of planning laws and Building Regulations, and we are unmatched.

Our Approach

You'll hear it here and nowhere else. Our approach is quite simple: "PERFECT THE SURVEY, PERFECT THE BUILD".

Whilst other companies play on pulling heart strings and highlight that they are a "family run business" we don't, we cherry-pick only the very best, from surveyor, builders, installers, plasterer's, electricians and compliance experts, we believe that if your outlaying serious money then you deserve a serious team to deliver your project, This all starts with a high standard Fensurv survey. 

Our surveys not only provide our installation and build teams with precise, simple-to-follow instructions, it provides our customers with absolute clarity on their project so that they can monitor and enjoy the entire process with confidence. Have a look at the example survey below. This is what we provide all of our customers.
