How It Works: Off-Plan DIY Heat Pump Engineering
Step 01
Self-Paced Portal Intake
Access your secure project portal to map out your DIY heat pump install at your own pace. Save progress as you go and submit for engineering review when ready:
- Floor Plans & Radiators: Floor plan layouts and current radiator locations, sizes and maximum available space for new emitters.
- Window & Door Schedule: Dimensions, glazing types, and frame specifications.
- Electrical & Plant Space: Photos of the electrical meter, main cut-out fuse, consumer unit , existing cylinder specifications and location.
- Current Heat Source: Photos, age, and location of your existing boiler.
Step 02
Dual-Scenario Engineering
We carry out the room by room calculations based on your plans and local climate data to BS EN 12831-17 to show two pathways for your installation:
- Option A (Minimum Disruption & Cost): Sized for the lowest capital cost, retaining as many radiators as viable.
- Option B (Maximum Efficiency): Sized for the lowest flow temperatures possible for your home giving maximum SCOP and the lowest running costs.
- Hydraulic Verification: Primary pipe sizing and DHW recovery performance.
- MCS 020 Sound Assessment: Acoustic distance calculations verifying boundary noise limits.
Step 03
Pack Delivery & Support
A comprehensive, installer ready engineering dossier delivered directly to your portal, ready for installation and compliance:
- Room-by-Room Schedules: Complete heat loss data and emitter schedule.
- Hydraulic Layout: Pipe sizing schedule and emitter locations, on plans, ASHP location and siting.
- Compliance Pack: Everything you need to meet standards for ASHP installation.
- Air Source Heat Pump: We will provide the relevant data for your heat pump output, user manuals, a place to keep and store warranty documents, service records etc.
Planning Notice: Verifying Permitted Development rights (e.g. AONBs, Conservation Areas, or Listed Building status) remains the property owners responsibility.
SECURE CLIENT PORTAL
Work At Your Own Pace. Never Lose Your Data
Gathering property dimensions and plumbing details can take time. Your dedicated project portal autosaves your progress, lets you upload photos directly from your phone, and acts as a permanent digital archive for your system’s lifetime.
Independent installer freedom & tender Ready
Tender Ready Blueprints. Direct Trade Freedom
The Boiler Upgrade Scheme often acts as an excuse for installers to inflate prices and push standardized, oversized units. Owning an independent blueprint gives you complete control over your DIY heat pump project—letting you purchase equipment direct, manage your own install, or hand the exact specification to any local tradesperson.
- Hire Any Competent Trade: Hand this complete engineering specification to any skilled local plumber or heating engineer—no MCS registration required.
- Direct Trade Purchasing: Buy heat pumps, cylinders, and radiators at genuine trade cost, bypassing typical 20%–40% contractor mark-ups.
- Guaranteed Standard Compliance: Engineered strictly to BS EN standards, complete with MCS 020 sound calculations and DNO-ready paperwork.
- Retain 0% VAT Relief: Any VAT-registered installer can legally apply 0% VAT to your heat pump hardware and labour under current HMRC energy-saving rules.
📐CIBSE & BS EN 12831-17 STANDARDS
Room-by-Room Accuracy
No rule-of-thumb estimates or inflated safety margins. Every calculation is mapped against your exact fabric U-values, room dimensions, and local climate data.
🛡️ INSURED CALCULATIONS
Professional Indemnity
Your engineering pack is backed by professional liability cover. You receive signed, verified hydraulic schedules ready for direct handover to trades and Building Control.
🏷️ ZERO MCS MARKUPS
Trade Pricing
Traditional installers inflate hardware costs by 20%–40% to pad their margins. We connect you directly with vetted manufacturers and trade merchants so you buy equipment at wholesale trade rates—cutting out the installer middleman entirely.
