By the time an installer visits, you're already being sold something
By the time an installer visits, you're already being sold something
Ask three different trades what a 1930s semi or Edwardian detached needs and you'll get three different answers - each shaped by what that company sells.
Surrey has a significant stock of pre-1919 solid-wall properties where standard installer advice, designed for simpler modern homes, rarely applies.
And with energy bills regularly hitting £600 a month or more in larger older homes, getting the sequencing wrong isn't just frustrating - it's expensive.

Our solution
An independent home energy survey, not a sales visit
Get the right advice for your specific home
Every property in survey is different, we survey yours first so nothing gets guessed or missed
We cut through the conflicting recommendations and give you one clear, sequenced plan you can trust
We don't sell insulation, heat pumps, or solar panels — so the advice reflects what your home needs, not what we have a financial interest in selling


Get a survey that covers your whole home
Physical inspection of walls, roof, floors, windows, and doors - recording construction type, insulation levels, and ventilation
Energy modelling - a government-approved digital model of your home, calculating the precise impact of each potential improvement
Additional elements include the checking cavity wall insulation
End with a plan that makes sense for you and your home
Phased recommendations with cost estimates, annual bill savings, CO2 reduction, and EPC impact per measure
Designed to be worked through at your own pace - the first step is often modest before committing to larger works
Paired with a consultation call to walk through the findings, answer questions, and agree next steps

What a Surrey home energy survey typically recommends
Remember, every home is different and we check over 40 different elements of your home. Your recommendations will be unique to you.
Ventilation
Older Surrey properties that have been progressively draught-proofed often have moisture management issues. A survey checks whether wet rooms have adequate extraction and habitable rooms have trickle vents, and recommends humidity-controlled fans where needed.
Solid wall insulation
For pre-1919 homes with solid brick walls, insulation is the highest-impact improvement. Internal insulation can be done room by room; external insulation covers a whole elevation and may require planning permission. Your assessor advises on the right approach for your specific property.
Loft Insulation
Many Surrey homes fall short of the recommended 300mm depth. A top-up is typically the most cost-effective first step. Loft legs allow full depth without losing storage.
Heating System Review
The survey assesses whether your current system is efficient and correctly sized, and advises on the right time to consider a heat pump - which should follow fabric improvements, not precede them.
Solar
Surrey's southerly location and stock of detached homes make solar a realistic option. Your assessor will check roof orientation and available area.

How it works
Step 1 - Book your survey
Start with a 15-minute, no-obligation chat to discuss your home and goals, and to see if we're a good fit for your what you're after
Step 2 - Home visit
Physical inspection and scan of your entire property - walls, roof, floors, windows, heating system, and ventilation. Typically two to three hours.
Step 3 - Energy modelling and plan
Your coordinator builds a digital model using our software and produces your Home Energy Plan - phased recommendations with cost, bill savings, CO2 reduction, and EPC impact per measure.
Step 4 - Consultation Call
Walk through the plan together, ask questions, and agree how to move forward - whether that's acting independently or asking Furbnow to manage the project.

FAQs
Frequently asked questions
For anything else just get in touch, we're a lovely bunch!
How much does a home energy survey in Surrey cost?
Furbnow's Home Energy Plan is a fixed-fee service. It covers the physical survey, RdSAP energy modelling, and your written plan including a consultation call with your coordinator. Genuinely independent advice isn't free - it isn't subsidised by a product commission. The fee is typically a fraction of what you'd spend on a single improvement.
How long does the survey take?
The home visit typically takes two to three hours depending on the size and complexity of your property. Your written plan is usually delivered within a few days.
Is Furbnow partnered with Surrey County Council?
Yes. Furbnow has worked directly with Surrey County Council to provide home energy surveys for Surrey residents, in some cases at a discounted rate. Several Surrey homeowners have come to Furbnow through council-promoted schemes.
What's the difference between a home energy survey and an EPC?
An EPC gives your home a standardised rating from A to G for regulatory purposes, with generic recommendations. A home energy survey goes much deeper - it's tailored to your specific property, considers your priorities and budget, and produces a sequenced plan with cost and savings estimates per measure. An EPC tells you where you stand. A home energy survey tells you what to do about it.
My home is a pre-1919 solid-wall property - can it be surveyed?
Yes, and this is precisely where an independent survey adds most value. Solid-wall properties require different insulation approaches from cavity-wall homes, and the options are more complex. Furbnow has extensive experience with solid-wall properties across Surrey and will advise on internal versus external insulation, the sequencing implications, and how to manage window junctions correctly.
Will the survey recommend I spend a lot of money straight away?
Not necessarily. A good survey tells you what you don't need to do as well as what you do, and the plan is designed to be worked through at whatever pace suits your budget. Many Surrey homeowners find the first priority is a relatively low-cost improvement - better ventilation or a loft insulation top-up - before committing to larger works.
What happens after the survey?
You receive your written Home Energy Plan and a consultation call with your coordinator. You can then act on the plan yourself, or ask Furbnow to manage the project - sourcing quotes from vetted installers, overseeing the work, and carrying out independent quality checks throughout.
How is a Furbnow survey different from a free survey offered by an installer?
Free surveys are carried out by companies that make money selling you a specific product. The advice you receive reflects that. Furbnow is not affiliated with any installer or product, so the recommendations are based entirely on what your home needs. Several Surrey customers came to Furbnow specifically after receiving conflicting advice from installer surveys.
