Home Upgrade Guide
"Every home needs a HUG"
Matthew Goldschmied
“A solution agnostic approach is outcomes based, where the most appropriate products, technologies and services are integrated in the context of a whole house retrofit, to minimise risk, protect the occupant, building, and its surroundings.
A whole house retrofit can be carried out in one or multiple stages.”
National Retrofit Hub
"69% of homeowners that searched for information online wanted advice that was more tailored to their property and their circumstances and 46% said that it was difficult to know where to start."
RVI's Home Upgrade Guide - HUG - is a bespoke, architectural whole-house improvement guide that prioritises long-term health, comfort, climate resilience and efficiency.
Upgrade your home with clarity, confidence and a professionally designed roadmap tailored for your home and your circumstances.
Before committing to costly works, you deserve a clear understanding of your home’s condition, performance and risks.
Some installations require specialist expertise but many retrofit measures are well suited to a DIY enthusiast.
Our HUG packages are structured to meet different needs — from early-stage guidance to full design and implementation support.
A detailed, architectural assessment of your home’s condition, performance and potential, designed specifically for your home.
Each HUG provides a safe route to improving comfort, reducing bills and avoiding retrofit mistakes.
Your Home Upgrade Guide provides:
-
A medium-term improvement plan (M-TIP) - the 'official' term for your HUG - aligned with PAS 2035 best practice
-
A forensic review of your home’s construction, condition, moisture behaviour and energy performance
-
A digital twin of your home
-
A phased sequence of upgrades that deliver maximum benefit with minimum disruption
-
Clear, actionable specifications you can give to installers or contractors
Quite simply, it’s the safest and most intelligent route to upgrading your home.
