Plug-In Solar UK Installers Guide: What Your Customers Are Already Asking

Plug-In Solar UK Installers Guide: What Your Customers Are Already Asking
Your customers are already in Facebook groups. They are reading about the government consultation. They are watching videos about German balcony solar. They are asking whether they can buy a kit from Amazon and plug it in themselves. Some of them have already tried.
They are going to call you. The question is whether you are ready for that conversation and whether you can turn it into work.
The plug-in solar market is not open yet. No product currently on sale in the UK meets the government's interim product specification. The policy response is expected 22 July. Compliant products are not expected before late 2026 at the earliest. But the customer interest is here right now, today, and the installers who get ahead of it will own the market when it does open.
This guide covers what the consultation means for your liability and your opportunity, what to tell customers who are already asking, and how to keep revenue moving while the market waits for compliant products.
What the Government Consultation Actually Means for You
On 16 June 2026, the Department for Energy Security and Net Zero launched a formal consultation on plug-in solar. It proposes amending the Plugs and Sockets (Safety) Regulations 1994 and introducing an interim product specification that every compliant UK product must meet. The consultation closes 30 June. A policy response is expected 22 July. You can read the full consultation on GOV.UK.
This is not legalisation. It is the start of the process that leads to legalisation. There is an important difference and your customers will not understand it without you.
What to Tell Customers Who Are Already Asking
Customers are confused because the headlines have been misleading. They heard "plug-in solar in shops within months" in March. They are now reading about a government consultation and do not understand why they cannot just buy one. Your job is to explain it clearly, position yourself as the expert, and keep them engaged until compliant products arrive.
The Job You Can Sell Right Now: The Plug-In Readiness Check
Every home that will eventually install plug-in solar needs a consumer unit check first. The interim product specification is explicit that homes with older unidirectional RCDs are not suitable for plug-in solar without an upgrade. That means every customer asking about plug-in solar today is a potential consumer unit job before any solar goes in.
This is the opportunity most installers are missing. They are waiting for compliant products before having the conversation. The smart move is to offer a Plug-In Readiness Check now, create a pipeline of assessed customers, and be first in line to complete the install when compliant products arrive.
What a Plug-In Readiness Check Covers1Consumer Unit AssessmentCheck whether the home has modern RCBOs or older unidirectional RCDs. Identify whether an upgrade is needed before plug-in solar can be safely installed. This is a billable job in its own right regardless of whether solar follows.2Circuit IdentificationThe interim spec requires plug-in solar to connect to a socket circuit, not a lighting circuit or a circuit supplying fixed equipment. Identify which circuits are suitable and document them. This saves time on the eventual install and demonstrates your expertise to the customer.3Siting and Shading AssessmentIdentify the best location for the panels. Note orientation, angle, shading from neighbouring buildings or trees, and mounting options. A south-facing install at 30 degrees generates around £110 a year. A north-facing shaded install generates significantly less. Give the customer a realistic number before they commit.4Socket Location and Cable RoutingAssess where the connection socket will be, how the cable will run from the panels to the socket, and whether an outdoor socket needs fitting. An outdoor weatherproof socket installation is a clean separate job you can complete now while the customer waits for compliant products.5Written Readiness ReportProvide a written report covering all of the above with a quote for any upgrade work needed and a confirmed price for the eventual plug-in solar installation. The customer now has a document, a plan, and a relationship with you. When compliant products arrive they are calling you first.What to ChargeA Plug-In Readiness Check typically takes one to two hours on site. A charge of £49 to £99 is reasonable depending on your area and the complexity of the property. Many installers offer it free to redeem against the eventual installation cost. Either approach creates a committed customer with skin in the game.The Pipeline ValueTen readiness checks at £75 each is £750 in immediate revenue. Ten customers with written quotes and a confirmed relationship is a pipeline of ten plug-in solar installations worth £2,000 to £4,000 in late 2026 labour alone. That is the value of acting now rather than waiting.The Consumer Unit Upgrade OpportunityA significant proportion of UK homes have older consumer units that will need upgrading before plug-in solar can be safely installed. A consumer unit upgrade typically costs £500 to £1,500 depending on the property. If your readiness check identifies that an upgrade is needed, you have a billable job to do right now, before a single solar panel arrives in the UK. That is real revenue from the plug-in solar opportunity today.Customers are confused because the headlines have been misleading. They heard "plug-in solar in shops within months" in March. They are now reading about a government consultation and do not understand why they cannot just buy one. Your job is to explain it clearly, position yourself as the expert, and keep them engaged until compliant products arrive.
When a Customer Says: "I Thought It Was Legal Now"Tell them: the government has confirmed the direction of travel. The framework is coming. The consultation launched on 16 June sets out exactly what compliant products must do. What is missing is compliant products — nothing currently on sale meets the UK specification. The delay is a regulatory bedding-in period, not a cancellation. Products are expected late 2026."This is not a cancellation. The government has published the product specification. Manufacturers now need to build to it. We expect compliant products later this year."When a Customer Says: "Can I Just Buy One From Amazon?"Tell them: no product currently on Amazon meets the UK interim specification. They use the wrong plug type, have not been tested to the UK standard, and are not registered on the ENA type test register as required. Buying one and connecting it to the ring main is not legal and could invalidate their home insurance. You are stopping them wasting money on something that will not serve them well."I can save you from a mistake here. None of those products are legal for grid connection in the UK right now. Let me tell you what to look for when compliant products arrive."When a Customer Says: "How Much Will It Actually Save Me?"The government's own figures are clear. A south-facing 800W system at optimal angle saves around £110 a year. East or west facing vertical saves around £70. But self-consumption rate matters — a customer who is out all day with no battery storage will save less than one who is home or has storage. Set realistic expectations now. A customer who understands the real numbers will not come back angry later."The government estimate is £70 to £110 a year. Your actual saving depends on which way your property faces and how much electricity you use during the day. Let me run the numbers for your specific situation."How to Position Yourself in Every ConversationTell every customer three things. We will guide you through what is legal, what is safe, and what is worth waiting for. We will notify you the moment certified UK products are approved. We will stop you wasting money on unsafe imports. That is the promise that builds trust and keeps customers in your pipeline until late 2026.

How High Efficiency Panels Let You Offer Solar to Customers Who Think They Cannot Afford It
A customer who says your quote is too high is not a lost customer. They are a customer with a budget constraint. High efficiency panels change the maths and open up a conversation most installers walk away from.
The standard small-scale solar install in Great Britain cost a median of £1,595 per kilowatt in 2025 and 2026. For a customer who wants 4kW that is over £6,000. Many customers who enquire about plug-in solar are not asking because they want a small system. They are asking because they cannot afford a full one.
High efficiency panels do not solve the budget problem entirely. But they reduce the number of panels needed to hit a generation target, which reduces mounting costs, labour time, and the overall job cost. For a customer with limited roof space, a north-facing extension roof, or a tight budget, the difference can be the difference between solar being viable or not.
This conversation works for three types of customer. The customer who cannot afford a full standard install. The customer with limited roof or wall space. And the customer who wants the lowest possible maintenance system with the fewest components. In all three cases high efficiency panels are the answer that keeps the job alive.
What You Can Sell Your Customers Right Now
Your customers are not going to sit on their hands until late 2026. They are interested in reducing their energy bills now. If you do not help them find a solution today, Amazon will. Or Temu will. And they will buy something that does not work properly, potentially creates a risk in their home, and leaves them frustrated with solar energy before the legal market even opens.
The installers who stay relevant this summer are the ones who understand the full picture. Plug-in solar is one part of it. Here is everything a customer can legitimately buy and use right now, and how you can be the person who guides them to the right choice.
