- Our Process
Our process is the difference
Great renewable heating isn’t bought off a shelf — it’s designed. From the first survey to the final commissioning, our process is what turns good equipment into a system that genuinely performs in your home.
- Why it matters
Most heat pump disappointment is a design problem
When a heat pump underperforms, it’s rarely the equipment’s fault. It’s almost always because the system was sized by rule of thumb, set to run too hot, or fitted without really understanding the property. The result is higher bills and a homeowner who wishes they’d stuck with gas.
We built our business to do the opposite. Every project is led by a detailed heat loss survey and an in-house design, so the system is right before a single tool comes out of the van. It takes more effort up front — and it’s exactly why our installs keep homes warm and running costs low.
From site assessment to final commissioning, we prioritise precision and attention to detail — and finish every job with Passiv smart controls so your system stays at its best for years.
The numbers that drive everything
Room-by-room
We calculate heat loss for every room, not the whole house as a single number — so each space is comfortable.
Low flow temps
We design to the lowest practical flow temperature, the single biggest lever on real-world efficiency.
10-year warranty
As a Vaillant Advanced Partner, our heat pump installs come with an exclusive 10-year warranty.
Your journey, step by step
Eight clear stages, with you informed at every one — from first call to long-term aftercare.
- Step 01
Initial enquiry
Get in touch and tell us about your home, your current heating and what you'd like to achieve. We'll answer your questions honestly and explain your options with no pressure.
- Step 02
Free estimate & eligibility
We provide a free, no-obligation estimate and check your eligibility for grant funding such as the Boiler Upgrade Scheme, so you understand the likely cost from the outset.
- Step 03
Home assessment & heat loss survey
We carry out a detailed survey of your property, measuring room-by-room heat loss and assessing your existing system, insulation and emitters. This is where every good installation begins.
- Step 04
In-house heating design
Our designers specify a system sized precisely for your home — the right heat pump, emitters and cylinder, designed to run at low flow temperatures. This is the step that determines long-term efficiency and comfort.
- Step 05
Proposal & recommendation
You receive a clear, honest proposal setting out the recommended system, expected performance, costs and any grant support — with time to ask questions.
- Step 06
Passiv controls setup & commissioning
We commission your system and configure smart Passiv controls, optimising performance so your system runs efficiently and weather-compensates from day one.
- Step 08
Handover & aftercare
We walk you through your new system, explain how to get the best from it, and provide ongoing servicing and support for the long term.
How our process adapts to each technology
The principles stay the same, but every technology gets a tailored approach. Here’s what leads the work on each — explore any service for the full detail.
Air Source Heat Pumps
Design-led, never one-size-fits-all
Most heat pump disappointment comes down to poor design, not poor equipment. Our approach puts a detailed, room-by-room heat loss survey at the centre of every project — so the system we specify is the right one for your home from the very first day.
Solar Panels
Designed around how you actually use energy
A solar array is only worth installing if it pays back. Our approach starts with your real energy habits and your roof's true potential — then designs a system that maximises self-consumption rather than just covering a roof in panels.
EV Charging
A charger that fits your whole energy system
We treat EV charging as part of your home's energy system, not an isolated socket on the wall. Our approach makes sure your charger works safely with your supply and intelligently with your solar and tariff.
Maintenance
Care that protects your investment
Renewable systems reward good maintenance with years of efficient service. Our approach is thorough, honest and built around keeping both your performance and your warranties intact.
How we work, whatever the project
A few principles run through every job we do — from a single EV charger to a full heat pump installation.
Design comes first
We never shortcut the design stage. Accurate, room-by-room heat loss calculations are the foundation of a system that's efficient and comfortable — not an afterthought.
Clear communication
You'll always know what's happening and why. No jargon, no surprises — just straightforward updates at every stage of your project.
Tidy, respectful work
Our team treats your home with care, working cleanly and leaving everything as it should be when we finish.
