The right solution for your profile
An owner who lives in their home, a buy-to-let investor, a business, a farmer or an apartment block don’t share the same constraints or the same profitability. This page points you the right way: depending on your situation, we identify the most relevant mix of solar panels, battery, heat pump or insulation, then send you to the dedicated path.

A winning mix for every profile
The best installation depends less on the product than on your situation: building use, tax status, holding period, consumption profile. Here are the main families of projects and the direction we recommend for each.
Owner-occupier
You live in your home for the long term: it’s the ideal profile to aim for autonomy. Solar panels + battery to self-consume as much as possible, rounded out by a heat pump and insulation to cut the overall bill.
Buy-to-let investor
You rent out one or more properties: we favour what adds value to the property and improves the EPC rating without over-investing. Insulation, high-performance window frames and right-sized solar, with a focus on profitability and holding period.
Business & SME
Warehouse or office roof, heavy daytime consumption: large-area solar PV offers a fast return on investment. See our dedicated path for professional and commercial installations.
Farmer
Large agricultural building roofs and continuous electricity needs: agricultural solar turns your surfaces into income. A dedicated path with grants and tax rules specific to the sector.
Apartment block
Apartment building and common areas: collective solar and energy sharing call for a bespoke approach. We handle the consultation, sizing and allocation between units.
New build & first-time buyer
You’re building or doing a major renovation: it’s the time to integrate a heat pump, reinforced insulation and solar from the design stage, to aim for a near-neutral building and anticipate EPC requirements.
How we guide you
From profile to action plan
-
We pin down your situation
Building type, use, consumption profile, tax status and holding horizon: a few questions are enough to place your project in the right family.
-
We prioritise the right solutions
Rather than fitting everything at once, we rank: where to start for the best cost/impact ratio for your profile (insulation, solar, battery, heat pump).
-
We send you to the dedicated path
Business, agricultural, apartment block: each profile has a dedicated page with grants, prices and concrete examples to go further.
-
Tailored study & quote
We price the chosen mix in a single study, a single quote, a single point of contact: that’s the whole point of the one-stop shop.
6 project profiles covered
4 trades solar, battery, heat pump, insulation

Where to start
The order of works changes with the profile
We often hear “I want panels.” But the optimal order depends on your profile. An owner-occupier often gains by insulating before generating; an investor aims at the EPC rating first; a business capitalises immediately on its large roof. We give you the most profitable sequence for your case.
- Owner-occupier: insulation, then solar + battery, then heat pump
- Investor: insulation and window frames first, for the EPC rating and value
- Business / farmer: large-area solar as a priority

Frequently asked questions
Choosing your solution by profile
I don’t know which profile I fit: how can I tell?
That’s exactly the role of this page and our study. Starting from your building type, its use and your project (living, renting, operating), we link you to the most relevant path. You can also combine several profiles: we then tailor the recommendation.
Do I have to install everything at the same time?
No. Depending on your profile, we prioritise the works to respect your budget: for example insulate first, then fit solar, then add a battery or a heat pump. The whole point of the one-stop shop is precisely to plan a coherent trajectory over time.
Which profile benefits most from solar PV?
Profiles with heavy daytime consumption — businesses, farmers, but also owner-occupiers home during the day — pay off their panels the fastest, because they directly self-consume the generation. For other profiles, a battery or energy sharing improves profitability.
And if I’m a buy-to-let investor: is solar worth it?
It all depends on your horizon. For a property held for a long time, solar can be worthwhile. To add value and rent out faster, insulation and window frames that improve the EPC rating are often the priority. We reason in terms of return and holding period, not just installation cost.
Why go through a one-stop shop rather than several installers?
Because the solutions interact: a heat pump changes your consumption profile, and therefore the sizing of the solar and the battery. With a single contact, the study is coherent, the quote single and the after-sales centralised, whatever your profile.
