SimpliHeat turns a site survey into a room-by-room heat loss, suggests the system, runs the MCS 020 sound check and builds a client-ready proposal — all in one place, on any device.
Draw the plan, read the heat loss as you go, and send an MCS-ready proposal — without the evening admin.
Heat loss, MCS 020 sound, pipe sizing, the catalogue and the client paperwork — all in one screen, one login.
Fabric and ventilation loss to MIS 3005, with design temperatures, U-values and the working shown for audit.
The BUS £7,500 — or the £9,000 off-gas uplift — is applied to the quote automatically from the recorded fuel.
A clean, professional PDF the homeowner can trust — heat loss, plant, sound and quote, presented as your firm.
Install it to your phone or tablet, draw with your finger, and keep surveying with no signal — it syncs later.
No surveying in one app and waiting to see the numbers in another. Draw the property, and the heat loss, the suggested kit, the sound check and the pipework all fall out as you go.
Drag out rooms and the walls snap square — down to the centimetre. Drop in windows, doors, stairs and extra floors. Rooms that touch share their walls automatically, so internal and external fabric are sorted for you.
Every room shades by how hard it's working, and every wall tints by its own loss, so the worst surfaces jump out. Flip retrofit on to show the before-and-after of better glazing or insulation. The total updates as you draw.
| Element | U | Loss |
|---|---|---|
| External walls | 1.50 | 384 W |
| Windows ×2 | 2.80 | 412 W |
| Floor | 0.70 | 198 W |
| Ventilation | 0.5 ach | 148 W |
| Room total | 1142 W |
From the heat loss and your flow temperature, SimpliHeat sizes the radiators and underfloor, then suggests a heat pump and cylinder that actually meet the property. Green when an emitter meets the room, amber when it needs a rethink. Pick the suggestion or override it — your call.
One screen, one login: the survey, the calculations, the kit, the compliance checks and the client paperwork. Here are fifteen of them.
Assessment positions, barriers and line-of-sight, with a clear PASS/FAIL on the proposal. No second app.
Place the heat pump and cylinder and SimpliHeat works out the run, the size and the velocity check.
A growing library of heat pumps and radiators to choose from — star your favourite pumps so suggestions land faster.
Take several at once; each is branded with the room, date, your name and the site address, straight into the PDF.
Heat loss, schedule, plant, sound, pipework, a BUS note and an indicative quote — assembled into a PDF.
Generate and submit the network operator application from the design, so you don't do it separately.
Coming soonWork saves to your device and syncs to your account, so any of your team can pick up a survey anywhere.
Design temperatures, U-values, ΔT-corrected outputs and non-standard temperature reasons — all recorded.
Drop a wall and the number moves. The plan tints room by room, cool to hot, so the heavy rooms jump out.
Existing and proposed emitters checked at your flow temperature, plus underfloor heating sized to EN 1264.
From the load and flow temperature, the right heat pump and cylinder — with capacity margins and COP shown.
Toggle fabric improvements and watch the load fall, room by room, with the percentage saved on the proposal.
The £7,500 grant — or the £9,000 off-gas uplift — applied to the quotation automatically from the recorded fuel.
Draw each storey; the loads, the heat-tinted plans and the pipework all span floors in a single project.
Add it to your home screen and keep surveying with no signal — it syncs the moment you're back online.
Everything you've worked out, assembled into a clean, branded PDF a homeowner actually understands — not a spreadsheet dump.
Choose which sections to include, add your company details, logo and accreditation numbers, and save reusable templates so every quote goes out consistent and on-brand.
Section toggles, business details & templates — rolling outDraw each room on your phone or laptop. Add windows, doors, construction and a few photos as you walk the property.
Heat loss, suggested radiators or underfloor, the heat pump, the cylinder, the sound check and the pipework all resolve live.
Export an MCS-ready proposal PDF with the design, the photos and the quote — and send it before you've left the drive.
Ready to try it on a property you know?
Most setups mean a survey app on site, a sync back to the office to see the numbers, a separate sound calculator and a spreadsheet for pipes. SimpliHeat keeps it in one screen.
Comparison is against a typical multi-tool installer workflow. SimpliHeat is new and growing — some things established tools offer, such as LiDAR room scanning, EPC address autofill and trade-kit ordering, are on our roadmap. All design outputs are indicative and should be confirmed with a full MCS survey.
Launch pricing while we're growing — we'll confirm final plans as the product matures.
Question, feature idea, or want a walkthrough? Drop us a line and we'll get back to you.
SimpliHeat installs straight to your phone, tablet or laptop — add it to your home screen and it opens full-screen like a native app, keeps working offline on site, and syncs the moment you're back on signal. No app store, no waiting.
On iPhone & iPad: tap Share → Add to Home Screen. Dedicated App Store & Google Play builds are on the roadmap.
SimpliHeat's calculations follow recognised UK and European standards and guidance. The figures are a design aid — always confirmed by your full MCS survey and certification body.
The Microgeneration Certification Scheme standard for heat pump system design and installation.
The planning-standard sound assessment for air source heat pump permitted-development.
The European method for calculating a building's design heat load, room by room.
The CIBSE Domestic Heating Design Guide — temperatures, air change rates and design practice.
Paperwork prepared with BUS grant applications in mind for eligible heat pump installs.
Emitter outputs and heat pump performance taken from published manufacturer datasheets.
