Ready to fix your cold home for good?

Get peace of mind you're making the best decisions for your family

No generic recommendations - we assess your whole home, identify where heat loss is coming from and which energy upgrades are right for you, and create a plan that addresses your priorities in the right order.

Find out why your home is losing heat

We survey your whole home, from insulation to ventilation to heating systems, to understand where you're losing heat and how your home could be more energy-efficient.

Understand which upgrades make sense, and when

We model the potential energy savings and costs for each upgrade, taking your home's data into account. We'll tell you which investments are right for your home, and in which order, so you finally have a clear path forward.

Get a whole-house design and skip the guesswork

Whether you're planning a full renovation or taking it one step at a time, we'll provide all the details - products, materials, dimensions, floorplans - for any contractor to deliver your upgrades confidently.

Maybe you're planning a full renovation, or maybe you want to take it step-by-step. Every situation is unique. Our expert is there to understand your priorities and advise on the best approach for you.

"The team at Furbnow was very helpful to us and allowed us to understand what renovations would make a difference and those that would not impact our energy usage. We would recommend them to any homeowner considering improvements as they provide unbiased and actionable advice."

Why not go straight to installers?

Installers want to sell you their specific product, not necessarily what's best for your home. We're independent experts who assess what you actually need first.

Prevent expensive mistakes

We've seen customers spend £8,000 on cavity wall insulation their walls weren't suitable for and causing damp. Proper assessment prevents this.

Get the whole picture

Insulation, ventilation and heating systems all interact with each other. We consider these interactions - individual installers won't.

End the confusion

Stop getting conflicting advice from different installers. Get one independent expert view on what your home actually needs.

"Furbnow have been really helpful in explaining the whole process clearly. Lots of builders we spoke to when trying to do retrofitting ourselves didn't seem to know what they were talking about. I know we're in safe hands with Furbnow."

From heritage homes to modern builds, we've got you covered

We work with a huge range of property types, including listed buildings and homes in conservation areas.

How it works

Book a home survey

We send a qualified retrofit assessor to survey your entire home for roughly two hours. They'll look at everything - walls, roof, floors, windows, heating system, and ventilation - collecting data to inform our recommendations and plan.

Review your options

An expert coordinator will walk you through our survey findings and which upgrades we recommend, with estimated costs and savings. You decide which ones you’d like us to include in our design.

Get your BuildPack

We deliver a full plan and design for your chosen upgrades. The plan is split into phases, with detailed instructions on what exactly should be installed, how, where and when.

Take it to installers

We'll give you quotes from recommended, vetted contractors in our supply chain. Or you can take the pack to your own builders, architects or installers.
