SOUND FAMILIAR?
Three quotes. Three different heat losses. Three different heat pumps. One confused homeowner.
If you’ve started your air source heat pump journey, you’ve probably discovered the strange world of heat pump sales: companies asking you to pay for a heat loss calculation just to get a quote, surveys done from satellite photos, and proposals that can’t even agree on how much heat your home loses — let alone what size heat pump you need.
None of that is your fault, and none of it is normal in any other branch of engineering. A heating system should be designed once, properly, by someone with no stake in what gets installed. That’s what we do.
SYMPTOM 01
Quotes that disagree
One says 5 kW, one says 12 kW, one says your radiators are fine, one wants to change them all. Somebody is guessing.
SYMPTOM 02
Pay-to-quote surveys
Being asked to pay each installer for their own heat loss calculation — before you can even compare prices.
SYMPTOM 03
Sales pressure
Discounts that expire tonight, brands pushed because of installer margins, and answers that change when you ask twice.
THE FIX
Independent design
A measured, room-by-room design from an engineer who isn’t selling an installation. Then installers simply price the same job.
WHAT WE DO
Independent Design Services
One principle: the design comes first.
Educate first. Design properly. Recommend honestly. Every service we offer exists to separate the engineering from the selling.

HOW IT WORKS
From first enquiry to a system that just works
01
STEP ONE · BY EMAIL
Tell us about your project
Complete the short enquiry form. We review it personally and reply with the most appropriate next step — no call centres, no pressure.
02
STEP TWO · AT YOUR HOME
Technical survey & LiDAR measurement
We measure every room, every window, every wall construction — and survey your existing radiators, pipework, electrics and emitter circuits.
03
STEP THREE · THE ENGINEERING
Room-by-room heat loss calculation
Every room calculated to recognised UK methodology at your local design outside temperature. No floor-area shortcuts, no assumptions where facts exist.
04
STEP FOUR · THE DESIGN
Full system design
Heat pump selection from manufacturer performance data, radiator schedule, cylinder sizing, pipework and controls — documented so any competent installer can price and build it.
05
STEP FIVE · YOUR CHOICE
Installation by a vetted MCS installer
If you wish, one of our small network of trusted MCS certified installers builds the design without alteration or sales conversations — and handles the £7,500–£9,000 Boiler Upgrade Scheme grant and paperwork.

GUIDE
Can my existing radiators work with a heat pump?
Often yes — here’s how designers check, radiator by radiator.

GUIDE
What size heat pump do I need?
Why sizing comes from measurement, and why bigger is not safer.

CASE STUDY
A 1930s semi in Wakefield, designed properly
Three quotes told this family three different stories: heat losses ranging from 5.9 kW to 11.2 kW, and radiator schedules that ranged from “keep them all” to “replace the lot”. We measured the house room by room, found the truth at 6.8 kW, and designed a system running at just 45 °C flow — keeping seven of the ten existing radiators.
- Measured heat loss 40% below the highest quote
- 7 kW heat pump instead of the quoted 12 kW unit
- Seven of ten radiators retained after output checks
- Installed by a vetted MCS installer, exactly to design

QUICK QUESTIONS
Before you ask…
The four things almost everyone asks us first. Longer answers live in the Advice Centre.
No — and that’s the point. We design systems and, where you’d like us to, hand the finished design to one of a small network of trusted, vetted MCS certified installers who build it without alteration. We take no commission from them.
We’re based in West Yorkshire and provide our full survey and design service throughout England, Wales and Scotland. Design reviews and desktop calculations are location-independent.
Yes. Our designs are produced to the standards MCS installers need, so your chosen installer can claim the Boiler Upgrade Scheme grant — £7,500, rising to £9,000 for oil and LPG homes from July 2026 — and handle all the paperwork.
Absolutely — that’s our Independent Design Review service. We compare the heat losses, sizing and radiator schedules in your quotes and give you a plain-English verdict on each.
