We deliver the complete new-build solar package as a single accountable supplier — design, supply, installation, certification and aftercare. Services are grouped into four silos below: generation systems, storage and integration, design and compliance, and aftercare. Developers typically procure the full stack; self-builders mix and match.
Services
New build solar services
Everything required to deliver FHS-compliant solar PV on a new build — from system design and SAP/HEM modelling through in-roof and BIPV installation to battery, heat pump, EV charging and aftercare.
Generation systems
In-Roof Solar Integration →
Factory-fitted in-roof PV systems integrated into the roof structure during construction — the FHS-default specification.
Building Integrated Photovoltaics (BIPV) →
Solar tiles, solar slates and PV-glass facades — for premium plots and Conservation Areas.
Solar Inverters →
Hybrid, string and micro-inverter specification — SolarEdge, SunSynk, Enphase, GivEnergy, Fronius compared.
Storage & integration
Battery Storage Integration →
AC-coupled and DC-coupled batteries sized for FHS half-hourly self-consumption modelling.
Heat Pump Integration (ASHP) →
Solar-paired air source heat pumps — the standard FHS heating package.
EV Charge Point Integration →
Solar-aware EV charging that diverts surplus PV to the car instead of export.
Smart Energy Systems →
Unify solar, battery, heat pump and EV charging under one intelligent control layer — Loxone, Home Assistant, Hubitat.
Design & compliance
Solar System Design →
Architect-led PV design from RIBA Stage 2 — 3D layout, SAP/HEM modelling, full Building Control pack.
SAP & HEM Compliance Modelling →
Full SAP 10.3 and Home Energy Model assessments certified by Elmhurst, Stroma and BRE-accredited assessors.
Developer Procurement Packages →
Bulk solar+battery+ASHP packages priced per-plot across whole sites.

For developers and housebuilders
New build solar services for volume new-build programmes
Per-plot pricing locked at procurement. Factory pre-fit on panelised roof cassettes. SAP/HEM modelling for every house type included. NHBC, LABC, Premier and Buildmark warranty-accepted workmanship. 20-year insurance-backed system warranty. We work with developers from 50 plots to 5,000+ across multi-site frameworks — agreed pricing, agreed programme, agreed warranty stack.
For self-builders and architects
New build solar services for one-off custom builds
Engagement from RIBA Stage 2. PV sizing collaborative with the architect. SAP/HEM modelling that gives the architect freedom on glazing ratios and roof geometry. Building Control submission pack ready for the Approved Inspector. 0% VAT on new-build dwellings. Staged invoicing aligned to your self-build mortgage drawdowns. We work with custom-build buyers across England, Wales and Scotland.
How this fits into the FHS compliance pathway
Every FHS-compliant new build must pass three regulatory gates. New build solar services fits primarily into the second gate — design-stage Part L compliance — but has knock-on implications for Building Control sign-off and post-completion warranty:
- 1 Planning permission Most solar PV on new dwellings is consented within the dwelling\'s primary planning consent. Conservation Areas, Article 4 directions and listed-curtilage plots require additional planning consideration — we handle the planning evidence required for these.
- 2 Building Control — Part L compliance SAP 10.3 or HEM compliance modelling demonstrating Dwelling Emission Rate ≤ Target Emission Rate. PV specification, ASHP capacity, fabric U-values and air permeability all entered into the modelling. We provide the full compliance file ready for the Approved Inspector.
- 3 Post-completion — warranty & EPC MCS certificate, EPC, monitoring app onboarding and 20-year insurance-backed workmanship warranty. NHBC, LABC, Premier and Buildmark all accept our installation specification without query — important if you\'re relying on a structural warranty for buyer mortgageability.

Frequently asked
Common questions
Answers to the questions we get most often when discussing new build solar services with new clients.
When does the Future Homes Standard come into force?
24 March 2027 in England, with a 12-month transitional period running to 24 March 2028 for projects already under construction. The Approved Documents L and F were published on 24 March 2026 (Government statement HCWS1445), giving the industry exactly 12 months of certainty before regulatory commencement. Scotland, Wales and Northern Ireland are following with broadly equivalent regulations on roughly aligned timetables, although devolved nuances apply — Welsh regulations are typically 6 months ahead.
What does FHS-compliant solar PV actually cost per plot?
The Government Impact Assessment puts the total FHS premium at ~£4,350 per dwelling per dwelling (2025 prices, weighted average across heat pump, solar PV, MVHR and enhanced fabric). Of that, solar PV is roughly £4,200 — covering ~3.4 kWp for a typical 3-bed semi (panels, in-roof mounting, inverter, monitoring, MCS certification and 20-year insurance-backed warranty). Larger dwellings cost proportionately more; volume procurement reduces per-plot cost by 20–25%.
Will the 40% PV rule actually be enforced?
Yes — the rule is a functional requirement in the Approved Document, not guidance. Building Control sign-off requires SAP/HEM modelling demonstrating compliance. The previous Part L 2021 token "2-panel" systems no longer pass, since they fall ~85% below the 40% benchmark. The deemed-to-satisfy route requires the full 40%; alternative compliance through enhanced fabric is possible but rarely cost-effective.
Can I exceed FHS minimum specifications?
Yes — and many self-builders and premium developers do. Marginal capital cost of a larger array (e.g. 5 kWp instead of 3.4 kWp on a 3-bed) is only £1,000–£1,200, while the additional generation pays back in 3–4 years at 2026 electricity tariffs. Upgrades that fit easily on top of an FHS-compliant base include battery storage (£3,500–£5,000), larger array size, EV charge point pre-fit (£600) and air permeability below 2 (achievable with deliberate detail).
