Renewable Heating System Surveys
After over forty thousand surveys and over fifty years of collective experience of working with renewable heating systems, we know exactly what to look for, and exactly where to look for it. With low temperature heating systems becoming mandatory in 2025 its the perfect time to start looking at air source heat pumps.
This has allowed us to provide industry leading, award winning in-depth technical surveys for:
​
-
Air Source Heat Pump Installations
-
Ground Source Heat Pumps Installations
-
Water Source Heat Pumps Installations
-
Biomass Boiler Installations
-
Hybrid System Installations
​
Aftercare and guidance is important to us. We set up private WhatsApp groups with all of our installer clients, allowing you to communicate directly with our administration and design teams with any questions or queries, cutting out hold times over the phone.
​
Our expert industry knowledge is second to none, with a support network dedicated to help you get the most out of your installations.
What We Offer
Qualified Experience
​
We have the largest network of qualified Domestic Energy Assessors in the UK, all with a wealth of experience in surveying domestic properties in preparation for new/replacement heating systems, with in-depth knowledge of the web of regulations, best practices and safety requirements of renewable systems.
​
Consistent Documentation
​
We have put a huge amount of focus into our surveys to make them the best they can possibly be, without overcomplicating the data. We understand the importance of clarity, which is why our surveys are the same, every time.
​
Efficient Delivery
​
We know how important it is to plan your installations efficiently, and that you need the survey quickly. We aim to hand over a completed survey with a strict twenty four hour turnaround from survey appointment time (forty eight hours if a heat loss calculation is also required).
​
Complete Coverage
Our surveyor network covers the entirety of England, Scotland and Wales, giving us access to around 95% of domestic properties in the country. Wherever it may be, we'll get there.
What You Get
Complete Floor Plans
Using manual and digital measuring methods, our surveyors measure every part of the property, both inside and out, to ensure that any heat loss calculations are as accurate as possible.
​
With our floor plans, you have a presentable, digital footprint that is exactly to scale.
​
A Technical Survey
Our surveys are renowned across the industry for being highly detailed and highly accurate, without the time-consuming commitment.
​
Complete with 360 photos, extensive video walkthroughs of the property, and the floor plans, you have a complete overview of everything you need to know about the property prior to installation.
A New/Draft EPC
As standard, a draft EPC is populated with every survey we complete.
​
Need access to funding? No problem; our qualified DEA's can also provide pre-measure and post-measure draft EPC's for you to display rating improvements to your customer, and for you provide accurate running costs to your customer prior to your installation.
Heat Loss Calculations
Alongside the technical surveyors, we have a full time, in-house design team with a collective 30+ years of experience in designing heating systems and performing heat loss calculations.
​
Working to the standards and methodology set out in MCS3005-D and the CIBSE Domestic Heating Guide, our service includes:
​
-
Complete, room-by-room heat loss calculations for the full property
-
A detailed heat loss summary
-
Required emitters with outputs at required flow temperature
-
Details of the proposed equipment (such as SCoP, maximum output, etc)
-
MCS035 Model Performance Estimation
-
MCS020 Sound Calculations
-
MCS Compliance certificate
-
Recommended equipment
-
Any site-specific recommendations
​
As an optional extra, alongside the heat loss calculation, our design team can also provide a completed DNO application form with the relevant unit-specific technical information and assist you with the application process, saving you time with your pre-installation administration.
