The construction of the property
We establish whether the home has solid walls, cavity walls, a loft that needs topping up, or a combination of issues that should be solved together.
Free Survey
Book a free home survey.
Whether you're considering external wall insulation, cavity wall insulation, or loft insulation, we'll assess your property, explain the right solution, and leave you with a clear best-next-step recommendation for your home.
This platform has completely transformed how we approach customer outreach. The results speak for themselves.

How it works
A clear process from first survey to finished home.
We call you back
During office hours, one of our team will usually call promptly to confirm the basics, answer any immediate questions, and arrange a convenient time to visit.
We survey the property
We look at the construction of the house, the condition of the walls or loft, any signs of damp or condensation, and the kind of result you are hoping to achieve.
We recommend the right option
If external wall insulation is right, we will say so. If cavity wall insulation or loft insulation is the better-value move, we will tell you that instead.
You receive a clear written quote
You get a detailed quotation and practical advice, then take your time. There is no obligation and no hard sell attached to the visit.

- You receive a clear quotation with the work explained in plain English.
- If a service is not suitable for your property, we'll tell you honestly.

- No pushy follow-up calls
- No hidden costs or surprise extras
- No recommendations for work you do not need
What we assess during the survey
Heat-loss priorities
We help you understand where the biggest gains are likely to come from, so you do not spend money on the wrong improvement first.
Signs of damp or condensation
Cold walls, moisture, and mould concerns all matter. We factor them into the recommendation instead of treating insulation as a one-size-fits-all answer.
Finish and appearance
If you are considering external wall insulation, we can talk through render finishes, colour options, and what the completed property could look like.
Practical access and installation details
We assess access, scaffolding implications, awkward areas, loft use, and anything else that will affect how the job would actually be carried out.
Budget and best next step
Some customers need the highest-performance solution. Others want the quickest and most affordable improvement. The survey helps separate those paths clearly.
Still comparing services?
If you are not yet sure what the property needs, these pages will help you compare the likely routes before the visit. The survey then confirms which of them genuinely fits your house, budget, and priorities.
External wall insulation
For solid-wall homes, colder properties, or customers who want the biggest thermal improvement and an exterior transformation.
Cavity wall insulation
For suitable cavity-wall properties where a fast, discreet, and cost-effective upgrade may be the right answer.
Loft insulation
For homes losing heat through the roof and customers looking for one of the simplest, quickest wins for comfort and energy efficiency.
Questions about the survey
Is the survey really free?
Yes, completely free. Whether you proceed with us or not, there is no charge for the survey or the quotation.
What if I am not sure which insulation service I need?
That is exactly what the survey is for. Many customers are comparing external wall insulation, cavity wall insulation, loft insulation, or a combination of improvements when they get in touch.
How long does the survey take?
Most surveys take around 30 to 45 minutes, depending on the size of the property and how much you want to discuss.
Do I need to prepare anything?
Not much. It helps if we can access the outside of the property, and it is useful to have any questions ready about warmth, bills, condensation, or the look of the finished work.
Will I get a quote on the day?
We can talk through likely costs during the visit, but the formal written quotation normally follows afterwards once we have confirmed the detail properly.
Do you cover my area?
We cover Coventry, Nuneaton, Birmingham, and the wider Midlands. If you are unsure, send the enquiry anyway and we will confirm it quickly.
Can I book a survey even if I am only exploring options?
Yes. Many people book while they are still comparing routes and trying to understand what will make the biggest difference to their home.
