MCS paperwork and the DNO notification are handled for you, and the handover pack lists the serial number of everything we fitted.
Four builds, four prices.
These are starting prices for a standard pitched roof with straightforward access. Your exact figure is fixed after a free survey, and you can walk away at that point.

Prices include panels, inverter, battery where listed, scaffolding, bird protection, MCS paperwork and the DNO notification. They assume no roof repairs are needed first. We do not quote a savings figure before a survey, because it depends on your roof, your usage and your tariff. Your surveyor produces one calculated to the MCS method with the assumptions written down.
Finance is available on any of these builds. We show you the full terms after your survey rather than a teaser rate on a web page. How that works
Figure 1 · What we add to the house
One house, four measures, in the order we fit them.
-
00
As existing
A standard pitched roof, tiled, with straightforward scaffold access. This is the house the published price is written against.
- Roof
- Pitched, tiled
- Access
- Standard
- Survey
- 60 minutes
-
01
Scaffold
Erected to the eaves on the working elevation, with the hire period inside the price. Non-standard access is priced as its own line, never absorbed.
- Item
- Scaffold
- Included
- Erection, hire, strike
- Typical
- 1 to 2 days

02
Tiles lifted
Tiles are lifted in courses where the hooks land, then set aside. Nothing is cut that does not have to be.
- Courses
- Lifted at hook lines
- Tiles
- Retained and re-laid
- Breakage
- Replaced at our cost
-
03
Roof hooks
Fixed through to the rafters, not to the batten. Sixteen on this array. Photographed at this stage, before the rail goes on, because that is what the certification body wants to see.
- Fixing
- To rafter
- Quantity
- 16
- Evidence
- Photographed before rail
-
04
Tiles re-laid
The lifted courses go back over the hooks, so the roof is weathertight again before any rail is lifted up.

Mounting rails
Two rails, bolted to the hooks and set out so the array sits 300mm clear of the ridge and the verges.
- Rails
- 2 runs
- Clearance
- 300mm to ridge
- Material
- Anodised aluminium

06
The array
Ten 430W all black panels in two rows of five. On this roof that is 4.3 kWp. Each serial number is recorded against the design.
- Panels
- 10 x 430W
- Output
- 4.3 kWp
- Serials
- Recorded to design

07
The inverter
A hybrid inverter, usually in the loft on the gable wall, sized so a battery can be added later without replacing it. The scaffold comes down at this point, because the roof work is finished.
- Type
- Hybrid
- Position
- Loft, gable wall
- Battery ready
- Yes
-
08
The battery
10kWh below the inverter on the same wall, keeping the cable run short. This is what carries the house overnight and charges on a cheap night rate.
- Capacity
- 10 kWh
- Position
- Gable wall
- Charges
- Off peak

Air conditioning
A reversible unit, quoted separately. It cools in summer and heats in winter, and it runs on what the array is generating in the months you need it most.

Who stands behind it, and for how long.
Four separate cover periods run on a solar and battery installation, and they are not held by the same party. Workmanship is ours. The panels, the battery and the inverter are the manufacturer's, and we handle those claims on your behalf. Every term is written into your quotation before you agree to anything.
It is worth knowing which of those matters. A panel is a sheet of glass with no moving parts, and it is the component that essentially never fails, which is why a long panel figure is the easiest one for anyone to advertise. What fails is the inverter, the wiring, the roof fixings, the flashing and the battery integration. Every one of those is our work rather than the manufacturer's, and every one sits under the workmanship term. That is the one to compare.
- WorkmanshipOur labour. Fixings, flashing, rails, cable runs, isolation and the battery integration.
- PanelsHeld by the manufacturer. We handle the claim on your behalf.
- BatteryHeld by the manufacturer, written against a retained capacity figure that is stated in your handover pack.
- InverterHeld by the manufacturer. The component most likely to need replacing during the life of the array.

Cooling that runs on your own electricity.
Reversible air conditioning cools in summer and heats in winter. Fitted alongside solar, it runs on power you generated rather than power you bought, in exactly the months your panels produce most.
