Prices.
Why are your prices published when nobody else's are?
Because a price you can read at eleven at night, in your own kitchen, with a rival's website open in another tab, is worth more to you than a price delivered by someone sitting on your sofa.
The usual model is to keep the number back until a home visit, where it can be presented with pressure attached. We would rather you compared us before you gave us an afternoon, and if the figure does not stand up, you have lost a minute rather than three hours.
Will my price change after the survey, and why?
It might. A published price is a starting price for a standard pitched, tiled roof with straightforward scaffold access and a consumer unit that can take the new circuits. If your property matches that, the starting price is where your quotation starts.
It moves for reasons we can name: your roof needs work before panels go on it, the scaffold is awkward, your board needs upgrading. Those are the exclusions on the prices page, and your surveyor writes down which of them apply with a figure against each one. Then the price is fixed in writing and does not move again unless you change the specification.
What is not included in the published price?
Five things, and we list them rather than burying them. Roof repairs found at survey, non-standard scaffold such as bridging a conservatory or needing a road licence, consumer unit upgrades, tree work where shading is killing output, and structural work where a roof or a battery wall needs strengthening.
None of these get discovered on installation day and sprung on you. They are found at survey, before you commit, and priced in writing as their own line rather than absorbed into a total.
Do you price match?
No. The published price is the price, and we do not move it to get under somebody else's number.
The reason is the whole argument of this website. If a figure can be discounted on the spot because you produced a competitor's quote, then the original figure was never honest, and the customer who did not haggle paid more than the one who did. We would rather publish one number that we can defend and then defend it.
What we will do is show you exactly what is inside our price, so you can check whether the cheaper quote includes the same scaffold, the same inverter and the same paperwork. Quite often it does not.
The survey.
What does the surveyor actually check?
The roof, measured properly rather than estimated from an aerial photograph, including its pitch, its aspect and what shades it through the day. The loft, for the rafters the hooks fix into and for where a hybrid inverter can sit. The consumer unit, to see whether it can safely take the new circuits. The scaffold access, because that is a real line in your price. And where a battery can go with a short cable run to the inverter.
They also work out what will actually fit, which is not always what you hoped for or what an online tool guessed.
How long does it take?
About an hour for a standard house. Longer if the roof is complicated or there is more than one elevation in play.
Does it cost anything?
No. The survey is free, and nothing is sold at the visit. The surveyor's job is to find out what your property needs and write it down, not to close you.
Do I have to decide on the day?
No, and you are not asked to. You get a written quotation afterwards with the equipment listed, the price fixed and the assumptions behind any performance figure set out so you can check them. Read it in your own time.
Even once you have agreed, you have a statutory 14 day right to cancel under the Consumer Contracts Regulations 2013, because the contract is agreed in your home. If you cancel within it you get your money back, deposit included. The detail is on the terms page.
Savings and payback.
Why will you not give me a savings figure before a survey?
Because it depends on three things nobody knows yet: your roof, your usage pattern and your tariff. Two identical systems on two identical houses produce different savings if one household is out all day and the other is not, or if one is on a night rate and the other is not.
A figure produced without those is guesswork with a pound sign in front of it. It is easy to generate, it flatters whoever generates it, and it is the single most common way people end up disappointed with solar.
So when do I get one?
After the survey. Your surveyor produces a figure calculated to the MCS method, with the assumptions written down next to it, so you can see what usage pattern and what tariff it assumes and change them if they are wrong for you.
A number you can check is worth having. A number you cannot is not, which is why there is not one on this website.
What about payback period?
Same answer, for the same reason. A payback period is a savings figure divided by a price, so it inherits every assumption in the savings figure and adds a guess about future energy prices on top. You get one after survey, with those assumptions visible.
The installation.
How long does the installation take?
A typical domestic solar and battery job runs across a small number of working days once scaffold is up, and the scaffold itself usually goes up a day or two before. Your quotation gives the dates for your job rather than an average, because a bungalow with one clear elevation and a three storey house with restricted rear access are not the same piece of work.
Will I need scaffolding?
Yes, for anything on a roof. It is erected to the eaves on the working elevation and the erection, the hire period and the strike are inside the published price for standard access.
Non-standard access is priced as its own line and never quietly absorbed. Bridging a conservatory, a road licence, restricted rear access or a three storey lift are the usual cases.
Will my power be off?
For part of the work, yes. Connecting the inverter and the battery into your consumer unit means the supply comes off while that is done. It is planned, it is not all day, and the team tells you before it happens rather than after your freezer has defrosted.
Do I need to be home?
Someone needs to be there for access to the loft and the consumer unit, and for the handover at the end, where the system is demonstrated and the charge schedule is set up for your tariff. You do not need to stand and watch the roof work.
What happens to my roof tiles?
Tiles are lifted in courses where the hooks land, and set aside. Nothing is cut that does not have to be. The hooks are fixed through to the rafters rather than to the battens, and photographed at that stage, before the rail goes on, because that is the evidence the certification body wants to see.
The lifted courses then go back over the hooks, so the roof is weathertight again before any rail is lifted up. Anything we break is replaced at our cost.
What if it rains?
Light rain is normal working weather. High wind, ice or anything that makes working at height unsafe stops roof work, and we would rather lose a day than have someone come off a roof. If weather moves your dates we tell you and agree a new one. Internal work such as the inverter, the battery and the electrical connections can often carry on regardless.
After the install.
Who handles the certificate and the grid notification?
We do, both of them, and they are inside the published price. Your installation is registered so the certificate can be issued, and your Distribution Network Operator is notified that generation and storage have been connected. You do not have to chase either one.
You also get a handover pack. Keep it, because the certificate is what your energy supplier asks to see when you apply for export payments, and it is what a buyer's solicitor asks for if you sell the house.
How do I get paid for the electricity I export?
You apply to an energy supplier for an export tariff. It does not have to be the supplier you buy your electricity from, and the rates on offer differ, so it is worth comparing.
The application needs your certificate and your meter details, which are in the handover pack, and we help you register rather than leaving you to work out the paperwork on your own.
What happens if something goes wrong?
Ring 01935 315315 and tell us. The teams who installed your system are our own people rather than subcontractors, which matters most at exactly this point, because there is nobody for us to point at.
Your quotation sets out the workmanship warranty and the separate manufacturer warranties on the panels, the inverter and the battery, which run for different lengths of time. If you are not happy with how a complaint is handled, the escalation route is on the terms page.
VAT and finance.
What is the 0% VAT position, and when does it change?
Qualifying domestic solar and battery installations are zero rated for VAT until 31 March 2027. Every price on this website has that applied already, so there is no VAT to add at the end.
From 1 April 2027 the rate returns to 5%, not to 20%. On our most popular build at £9,300 that is about £465 added. The 0% VAT page sets out what changes and what does not.
Does air conditioning qualify too?
Reversible units qualify for 0% VAT on installation until 31 March 2027 where the installation meets the conditions. Air conditioning is quoted separately from a solar build, and the prices are on the air conditioning page, from £1,350 for a single room installed.
Is finance available?
Yes. You can pay outright or spread the cost.
We do not print monthly figures or a teaser rate on this website, because a monthly figure without the full credit terms beside it tells you almost nothing and is designed to be read as cheaper than it is. After your survey, when the real price of your installation is known, you get the interest rate, the length of the agreement, the deposit, the total amount payable and the total cost of the credit, in writing, before anything is agreed.
Credit is subject to status and affordability checks.
Still easier to just see the number.
