Solar Installers Near Me: Find MCS-Certified Installers

The quality of your solar installation depends as much on the installer as on the panels themselves. A poorly installed system will underperform, develop faults sooner, and could even damage your roof. Here is what to look for and what to avoid.

Must-haves

• MCS certification: The Microgeneration Certification Scheme is the UK's quality standard for renewable energy installations. MCS-certified installers are independently audited and must meet strict standards. For Smart Export Guarantee payments you need certification through MCS or a scheme accredited as equivalent, so MCS is the most straightforward route rather than a legal requirement in itself.
• Consumer code membership (RECC or HIES): These schemes offer additional consumer protection, including insurance-backed warranties and a formal complaints process. RECC (Renewable Energy Consumer Code) and HIES (Home Insulation and Energy Systems) are the two main schemes.
• Public liability insurance: Any installer working on your roof must carry adequate public liability insurance. Ask to see the certificate if in doubt.
• A clear, detailed written quote: The quote should specify the exact panel model, inverter type, mounting system, all costs (including scaffolding), warranty terms, and estimated generation. Vague quotes are a red flag.

Good signs

• Positive reviews on Trustpilot, Google, and local review sites
• Willingness to provide references from recent installations in your area
• A thorough site survey before providing a final quote
• Clear explanation of panel and inverter choices and why they suit your roof
• A workmanship warranty of 5–10 years in addition to manufacturer warranties
• Transparent about what is and is not included in the price

Warning signs

• Pressure to sign immediately or "today-only" discounts
• Quotes over the phone without a site visit
• Unwillingness to name the specific panel and inverter brands
• No MCS certification or reluctance to share their MCS number
• Unusually cheap quotes — if it seems too good to be true, it probably is
• Door-to-door sales approaches (reputable installers rarely cold-call)

When you receive multiple quotes, compare them on these key factors:

• Total cost per kW: Divide the total price by the system size in kW. A 4kW system at £6,800 is £1,700 per kW. This metric lets you compare quotes of different sizes fairly. Typical UK range: £1,250–£2,000 per kW.
• Panel efficiency and warranty: Higher efficiency panels generate more per square metre. A 25-year performance warranty is standard. Check the product warranty too (12–25 years).
• Inverter type and warranty: String inverters typically carry a 5–12 year warranty; micro-inverters often come with 20–25 years. Factor in replacement cost if the warranty is short.
• What is included: Ensure scaffolding, DNO notification, MCS registration, and all labour are included. Some quotes exclude scaffolding as a separate cost.
• Estimated annual generation: Reputable installers provide a generation estimate based on your specific roof orientation, pitch, and shading. Compare these figures across quotes — wildly different estimates suggest one installer has not assessed your roof properly.

Every solar guide tells you to use an MCS-certified installer. Almost none of them tell you how to check, which is the part that actually protects you. It takes about two minutes and it is free.

1. Ask for the MCS certificate number before the survey, not after the quote. A legitimate installer gives it without hesitation. Hesitation is itself the answer.
2. Search the public register at mcscertified.com by company name or your postcode. The register shows the certificate status and which technologies the company is certified for. Solar PV certification is separate from heat pump certification — a company certified for one is not automatically certified for the other.
3. Check the trading name matches. Sales companies sometimes subcontract to a certified installer. That can be perfectly legitimate, but you need to know which legal entity is certified, which one you are contracting with, and which one carries the warranty.
4. Confirm consumer code membership — RECC or HIES. This is what gives you an insurance-backed warranty and a complaints route if the installer ceases trading.

Why certification matters financially, not just for peace of mind. To be paid for the electricity you export under the Smart Export Guarantee, GOV.UK states you need to show that your installation and installer are certified through the Microgeneration Certification Scheme (MCS) or a scheme accredited as equivalent — the Flexi-Orb renewables scheme is named as one such equivalent. Ofgem's guidance for solar PV up to 50kW is the same: an MCS certificate or equivalent.

So MCS is the usual route, not the only one. Anyone telling you it is legally the only way to access SEG is overstating it. What matters is that you hold recognised certification for both the installation and the installer — and MCS is by far the most widely held and the most readily accepted.

Two practical points. SEG suppliers must offer a tariff but are free to set their own terms, and in practice their application and evidence requirements differ — so check what your chosen supplier will accept before you commit to an installer. You will also need a meter capable of providing half-hourly export readings. If an installer proposes a route other than MCS, that may be perfectly valid, but get written confirmation of which scheme they are certified under and check your intended SEG supplier accepts it.

You cannot judge a quote without knowing what normal looks like. These are the mean installed costs per kW for small domestic systems in 2025/26, from the government's own MCS installation data. The spread between the cheapest and dearest region is 16% — on a 4kW system that is roughly £1,196.

A quote above your regional figure is not automatically a bad deal. Scaffolding, a slate or flat roof, restricted access, microinverters and premium panels all cost more for legitimate reasons. The benchmark does not give you a verdict — it gives you a specific, defensible question to ask.

Three quotes are only useful if they are comparable, and by default they are not. Two things make them so:

• Cost per kWp. Divide the total by the system size. A £9,000 quote for 5.5kWp and a £7,500 quote for 4kWp are not what they appear — the first is cheaper per unit of capacity. Without this number you are not comparing anything.
• Scaffolding, itemised separately. It is priced by access and hire duration, not by system size, and it is the line that most often explains a gap between two otherwise similar quotes. See what scaffolding should cost.

Then check the specification is genuinely equivalent: panel make and wattage, inverter type, whether a battery is included and priced separately, and the four different warranties (panel product, panel performance, inverter, workmanship). Our quote comparison checklist covers the full list, and the questions to ask covers the conversation.

Worth knowing before you commit: costs that do not always appear on the quote, how long installation actually takes, and who handles the DNO notification (your installer should, and it should not cost you anything).
