Why Future Homes preparation can’t wait
The DLUHC consultation confirms that every new home approved from 2025 must deliver a 75-80% reduction in operational emissions compared to the 2013 Building Regulations. England alone added 234,400 homes in 2022/23, so even modest housebuilders have dozens of plots that need a redesigned spec.
- The Home Energy Model (SAP 11) becomes the default calculation engine. Every energy model revision will need to live beside plot records so auditors see a continuous data trail.
- The Impact Assessment estimates £4.6k–£6.2k extra capex per dwelling for fabric + heat pumps. Without a shared calculator you risk underpricing bids by six figures.
- The Clean Heat Market Mechanism also goes live in 2025, so ASHP supply will be strained. Toolfy helps you lock preferred SKUs and attach performance data to every order.
2025 timeline and accountability checklist
Now → Q1 2025
- Respond to the Future Homes consultation and lock preferred spec templates.
- Confirm who owns the Home Energy Model submission and carbon calculations.
- Start supplier due diligence (heat pumps, MVHR, PV) with Toolfy job templates.
Q2 2025
- Adopt SAP 11 trial runs on every site to see fabric gaps early.
- Bulk upload submittals, product certificates, and commissioning plans into Toolfy folders.
- Train installers and supervisors on the new 10-step QA routine.
Q3 2025 onwards
- Switch live sites to the FHS template (fabric + systems).
- Send resident-ready comms templates to marketing/sales teams.
- Schedule quarterly retrospectives; use Toolfy exports for Building Control queries.
Assign each bullet to a Toolfy task owner, add an Idempotency-Key for any API submissions (HEM exports, Building Control uploads), and track slippage from one dashboard.
Fabric-first specification upgrades
The notional Future Homes home assumes better insulation, lower thermal bridges, and higher airtightness. Mirror the spec below inside your Toolfy job templates so foremen know what “good” looks like.
| Element | Current Part L 2021 | Future Homes target | Action inside Toolfy templates |
|---|---|---|---|
| External walls | 0.18 W/m²K | ≤0.13 W/m²K | SIPS, ICF, or 150mm cavity with insulated linings |
| Roof | 0.13 W/m²K | ≤0.11 W/m²K | 500mm loft insulation, warm roof on flats |
| Floor | 0.13 W/m²K | ≤0.11 W/m²K | 150mm PIR + thermal breaks at thresholds |
| Windows | 1.4 W/m²K | ≤0.85 W/m²K | Triple glazing with insulated frames |
| Doors | 1.0 W/m²K | ≤0.8 W/m²K | Composite doors with insulated cores |
| Airtightness | 8 m³/hr·m² | ≤5 m³/hr·m² | Blower-door testing + airtight membranes |

Services, controls, and commissioning
Low-carbon heating
- • Air-source heat pumps sized for 35-45°C flow temperatures with oversized radiators or underfloor heating.
- • Hot water cylinders sized ≥200L with PV diversion and legionella cycles logged in Toolfy.
- • Smart weather-compensation controls plus load compensation thermostats.
Ventilation + renewables
- • MVHR units with ≥90% heat recovery and commissioning reports stored in the plot asset record.
- • 4kW+ PV arrays with DNO G99 approvals and MCS certificates auto-attached to Toolfy documents.
- • Optional home batteries or thermal stores flagged so marketing/comms teams can explain the benefit.
Build a contractor briefing pack in Toolfy that outlines evidence requirements: red-lined drawings, MCS certificates, heat loss calcs, and commissioning videos. Use approval rules so a job cannot close until uploads are complete.
Budget the uplift and de-risk delays
Plug your own unit counts and supplier pricing into the calculator. It mirrors the DLUHC impact assumptions and highlights the programme buffer you need to ring-fence with finance.

Data room + assurance workflow
Plot passports
- Home Energy Model exports with version control
- Air test + commissioning certificates
- Photo evidence (fabric, airtightness, services)
Programme controls
- Recurring Toolfy tasks for pressure testing, MVHR commissioning, and resident demos
- Slack/email alerts when evidence is overdue
- Idempotent API submissions to Building Control portals
Resident & sales packs
- Heat pump user guides and energy cost comparisons

Funding, procurement, and messaging
Finance checklist
- • Cite the DLUHC impact assessment (Option 2) when renegotiating lending covenants so banks understand the uplift.
- • Tag Toolfy invoices as “Fabric uplift”, “Low-carbon systems”, or “Commissioning” so finance teams can claim allowances.
- • Monitor Clean Heat Market Mechanism penalties (£3k per missing credit) and bake them into supplier contracts.
Customer messaging
- • Equip sales teams with Toolfy snippets highlighting 75-80% emission cuts and projected £/year running-cost savings.
- • Share resident-friendly maintenance plans that explain heat pump defrost cycles, MVHR filter changes, and summer shading.
- • Automate SMS/email nudges when Home Energy Model inputs change so tenants feel informed, not blindsided.
