How do I start the buying process?
Start by identifying your goals and checking your property. Then arrange a no-obligation survey — the surveyor assesses your home and provides an itemised quote. The five steps below walk you through the whole journey.
Identify your goals
Are you looking to reduce electricity bills, replace gas or oil heating, increase self-sufficiency, or all three? Knowing your priorities helps the surveyor recommend the right combination.
Check your property
Note your roof orientation, any shading, your current heating system, insulation levels and available space for a battery or hot water cylinder.
Get a no-obligation survey
A surveyor visits your home to assess suitability. This is the only way to get an accurate, itemised quote — not a guess from a satellite image.
Compare your quote
Review equipment brands, warranty terms, VAT treatment and finance options. Take it away — there is no pressure to decide on the spot.
Decide and proceed
If you go ahead, installation is scheduled and carried out through our MCS-certified partners. If not, that is completely fine.
What should I ask before getting solar, batteries or a heat pump?
The right questions help you compare quotes and avoid buying a system that does not match your home. Here is a checklist for each technology.
Solar panels — what to ask
- Is my roof orientation suitable? South, east and west-facing roofs can all work, but output varies.
- Is there shading from chimneys, trees or neighbouring buildings?
- What system size (kWp) matches my daytime electricity usage?
- Is battery storage included or available alongside the panels?
- What warranty comes with the panels and inverter?
Battery storage — what to ask
- What usable capacity (kWh) do I need for my usage pattern?
- Is the battery AC or DC coupled, and which suits my setup?
- What chemistry is used? Lithium iron phosphate (LFP) is common for home use.
- Can the battery be expanded later if my needs change?
- What is the warranty and expected cycle life?
Heat pumps — what to ask
- Has a full heat loss assessment been carried out for my home?
- Will my radiators need upgrading, or is underfloor heating recommended?
- Is a new hot water cylinder included in the quote?
- Where will the outdoor unit be sited for airflow and weather protection?
- How will the heat pump interact with my existing heating controls?
What are the most common mistakes to avoid?
- 1Buying a system sized for someone else’s usage rather than your own — a proper survey sizes the system to your home.
- 2Skipping the survey — an accurate quote needs a physical assessment of your roof, insulation and heating.
- 3Ignoring insulation before installing a heat pump — a heat loss assessment reveals whether insulation upgrades are needed first.
- 4Not checking whether the installer is MCS-certified — MCS is a recognised quality standard for renewable installations.
- 5Focusing only on upfront cost without understanding warranty terms, equipment tiers and aftercare.
