At Bristol Gas Co., we pride ourselves on delivering a thorough and professional service from the outset. As part of your journey towards a low-carbon heating system, we carry out a comprehensive heat loss survey—a key step in ensuring your new system is designed for maximum efficiency and performance.

Here’s what our heat loss survey includes:

🔍 On-Site Visit by a Senior Expert

Your survey will be carried out by our company director, who is also a Heat Geek Elite engineer, ensuring your home is assessed by one of the most experienced professionals in the industry.

🏠 Room-by-Room Heat Loss Assessment

We calculate the heat loss for each individual room, taking into account insulation levels, window types, floor and wall construction, and more.

📏 Emitter Sizing

We size all emitters (radiators or underfloor heating) accurately, based on the heat demand of each room. This ensures your home remains comfortable all year round while running as efficiently as possible.

🧱 Total Building Heat Loss

We assess the overall heat loss of the entire building, which is essential for correct sizing of your Air Source Heat Pump (ASHP) and eligibility for the Boiler Upgrade Scheme (BUS) grant.

🔌 Clamp Test & DNO Application

We carry out a clamp test to check your property's electrical capacity and gather the required information to submit a DNO (Distribution Network Operator) application where necessary.

📍 Siting of Equipment

We review and advise on the most appropriate and practical locations for the ASHP unit outside your home, as well as the cylinder and internal components.

💬 Full Scope of Works Discussion

We’ll talk through the full scope of works with you in detail, answering any questions you may have about the system, performance, timeline, or grant process.

📄 In-Depth Heat Loss Report

Following the survey, you will receive a detailed heat loss report. This includes all calculations and design considerations, and is a required document when applying for the BUS grant.

If you’re considering switching to an air source heat pump, this survey is the essential first step in designing a tailored, efficient heating system for your home.
