Full Rooftop Installations
MCS-Certified Solar Installations in Kent
For households that want the full deal: rooftop panels, inverter, optional battery, DNO paperwork, and an MCS certificate at the end so you can claim SEG export income, 0 percent VAT, and insurance-backed warranties.
Two Clear Routes
- DIY plug-in solar from £499: fence, balcony or garden-mounted, daytime self-consumption, removable hardware. See DIY pricing and specs.
- MCS-certified install from around £5,000: full rooftop system with SEG eligibility, 0 percent VAT, optional battery and EV charger integration.
What MCS Certification Unlocks
- SEG export income. Electricity suppliers require an MCS certificate before paying you for electricity you export back to the grid under the Smart Export Guarantee.
- 0 percent VAT. Domestic solar PV and batteries are currently zero-rated in the UK when installed by an MCS-certified installer, meaning a meaningful saving on a typical system cost.
- Insurance-backed warranty. MCS installs come with a consumer-code backed warranty that survives contractor changes and supports home resale.
- Larger system sizes. Not limited to the 800W plug-in envelope; standard 4kW to 10kW rooftop builds are normal.
- Battery and EV charger integration. Properly engineered, protected, and certified as one system.
Typical Pricing
| System | Indicative cost | Typical household |
|---|---|---|
| 4kW PV (approx. 10 panels) | £5,000 to £6,500 | Two to three bedrooms, modest daytime use |
| 6kW PV (approx. 14 panels) | £6,500 to £8,500 | Three to four bedrooms, some daytime load |
| PV + 5kWh battery | £8,500 to £11,000 | Evening load shifting, tariff optimisation |
| PV + battery + EV charger | £10,500 to £14,000 | EV households, full electrification path |
Indicative only. Exact pricing depends on panel count, roof pitch and access, inverter brand, battery capacity, and DNO requirements. We give a fixed written quote after a site survey.
What the Process Looks Like
- 1. Free initial chat. WhatsApp, phone or email. We cover your goals, roof type and budget.
- 2. Site survey. We check roof orientation, shading, loft space and consumer unit capacity.
- 3. Fixed written quote. Panel layout, inverter, battery (optional), expected annual generation, payback estimate and warranty terms.
- 4. DNO notification. Under G98/G99 connection rules, with your distribution network operator.
- 5. Install. Usually one to two days on site, with scaffold booked in advance.
- 6. Commissioning and MCS certificate. You receive the paperwork needed for SEG registration with your electricity supplier.
How to Choose Between DIY and MCS
- Pick DIY if you want fast, low-cost daytime self-consumption, removable hardware (good for renters and house-movers), and you do not need SEG income.
- Pick MCS if you want to maximise roof area, add battery storage, claim SEG export payments, get 0 percent VAT, or keep full insurance-backed warranties for house sale.
- Not sure? Tell us your roof, usage pattern and budget and we will give you a plain answer, not a sales pitch.
