Costs, grants, paperwork and timescales — answered with numbers, not sales copy.
Surrey, Hampshire and London — including Guildford, Woking, Farnham, Winchester, Basingstoke, Richmond, Kingston and the surrounding towns and villages. See our areas pages for the full list.
Yes — home solar panels, battery storage (including standalone batteries since February 2024) and heat pumps are zero-rated for VAT until 31 March 2027 in Great Britain.
The Boiler Upgrade Scheme provides £7,500 towards an air source heat pump for eligible homes in England and Wales. We handle the application as part of the installation.
Yes. Solar, batteries, EV chargers and heat pumps all involve DNO notification or approval (G98/G99). We prepare and submit it for every install — our right-first-time promise is measured on first-pass approval.
We design from your property's actual data, quote from the design, and publish forecast-vs-actual performance after installation. If the numbers don't support an install, we tell you.
Usually not — most domestic rooftop solar is permitted development. Exceptions apply for listed buildings and some conservation areas; we check this in the survey and handle the paperwork where consent is needed.
A typical 4 kWp system costs roughly £5,000–£8,000 installed. VAT is 0% on home solar until 31 March 2027. Adding a battery typically adds £2,000–£5,000.
Through the Smart Export Guarantee, energy suppliers pay for every kWh you export. We register the system and size the battery so you keep the most valuable kWh — the ones you use yourself.
Most home installs are one to two days on the roof. Our AI design and pre-validated paperwork mean the wait from survey to installation is weeks, not months — measured as survey-to-energisation time.
Yes — an AC-coupled battery retrofits to almost any existing array without touching the original inverter. It has been 0% VAT since February 2024 and is usually installed in a day.
It depends on your evening usage, your tariff and your generation. We model your real consumption first; most homes land between 5 and 15 kWh. Oversizing wastes capital on cycles you will never run.
Only if specified with backup capability — many are not. Tell us it matters and we design it in, including which circuits stay live.
Modern lithium units are typically warrantied for 10 years or a set energy throughput. We track battery health in monitoring so degradation is measured, not guessed.
The charger itself is usually permitted development, but every charge point must be notified to (or approved by) your electricity network operator. We handle that paperwork as standard.
Yes — a solar-aware charger can divert surplus generation into the car instead of exporting it. If you have or plan solar, tell us and we specify a compatible unit.
Typically £800–£1,200 installed for a 7 kW smart unit, depending on the cable run and your existing consumer unit.
With the duty cycle: which vehicles, what daily mileage, what dwell time. We model that first, then size the charging — see our fleet depot electrification service for depots.
Usually, yes — with honest design. The heat loss calculation tells us what the building needs; sometimes that means larger radiators or targeted insulation first. We tell you the numbers either way.
The Boiler Upgrade Scheme provides £7,500 towards an air source heat pump for eligible homes in England and Wales, and installations are 0% VAT. We apply for the grant on your behalf.
Most domestic air source heat pumps are permitted development under current rules. Listed buildings and some conservation areas need consent — we check and handle it in the survey.
A heat pump running at a seasonal efficiency of 3–4 turns each kWh of electricity into 3–4 kWh of heat. Paired with solar, a battery and the right tariff, most homes cut heating costs against a gas boiler — we model your case with your numbers before you commit.
Yes — modern units are air-to-air heat pumps and heat efficiently in winter. For many rooms it is both the cooling and the cheapest heating upgrade in one install.
A single-room split system is typically £1,500–£3,000 installed. Multi-split systems serving several rooms are quoted from the room-load design.
Very well — peak cooling demand lands exactly when solar generates most. On a sunny afternoon a solar-equipped home can cool essentially for free.
The outdoor unit is usually fine under permitted development for houses, with placement rules; flats, listed buildings and conservation areas differ. We confirm before any work is booked.
Most rooftop arrays on commercial buildings are permitted development, with exceptions near listed buildings and in some designated areas. We confirm status during feasibility.
Daytime-heavy consumers commonly see payback in 4–7 years, with the system designed for 25. We model it against your actual half-hourly data, so the forecast is yours, not an average.
Yes — we design the system battery-ready, and add storage when your tariff and usage justify it. Sometimes it pays from day one; the model tells us.
Solar and storage plant can qualify for capital allowances. We provide the itemised cost breakdown and generation forecast your accountant needs to claim correctly.
Rarely. Load management, on-site solar and storage can multiply what a constrained connection supports. We model the depot as one system before assuming a costly upgrade.
Eligible fleet operators can access grant funding of up to £1m per site right now. We prepare the application alongside the engineering design.
Yes — most depots should. We design the end state, then phase installation to match vehicle replacement cycles, so capital follows the fleet.
Vans, HGVs and mixed fleets. The duty-cycle model tells us what each vehicle class needs; the depot design serves the mix, not the average.
