Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate

The ONLY technical person, who has ever exceeded my own high standards !!!! Being a professional commissioning engineer of over 37yrs in the field of emergency power generation, I approached Ron for some advice on a GivEnergy battery issue as happy to state I don't know everything. Not only did he reply immediately, his advice got the system working and all on a Sunday. You really do not get support as good as this anywhere now for anything. Thank you Ron

Givenergy panels and battery had been offline for a couple of months after various changes by Givenergy to their app etc. Ron did a fantastic job of sorting it out - got things up and running almost immediately, followed by some fine tuning to get things fully configured. What a legend - great service, great comms, great result.

I contacted Solar Tech Support with an issuewith my solar and Ron went out of his way to help me. Despite the fact that I'm situated hundreds of miles away and he knew there'd be no business opportunity from my inquiry, Ron still chased solutions and helped me get an understanding of what I needed to do. I love working with people like this, people with integrity and service at the heart of what they do. I just wish hew was nearer!

Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.

Mr P · Jun 2026 Trustpilot

Great experience with STS great communication from Ron, very helpful and knowledgable. Installed me a second Givenergy battery to help take the strain off my original 9.5 that needs refurb due to a weak cell. They secured me an 8.2 arranged install. Levi arrived the whole install was done within 1.5 hours - great tidy job. Worked with me to alter my setup to allow easy removal of my 9.5 when i can get it away for refurb - very happy with their service and its reassuring to know there is a company out there that can help look after my givenergy system

What are solar export payments?

The Smart Export Guarantee is a UK government scheme that pays homeowners for any electricity they export to the grid from a renewable energy system. If your solar panels or battery generate more electricity than your home uses, the surplus is exported to the grid — and the energy supplier pays you for it.

How the Smart Export Guarantee works

1. Your system generates surplus

On a sunny day, your panels may produce 10+ kilowatt-hours, but your home only uses 8 kilowatt-hours. The remaining 2 kilowatt-hours is surplus.

2. Surplus is exported to the grid

Your inverter automatically sends that surplus to the local electricity grid. This helps other homes in your area get their electricity.

3. The supplier pays you

Your energy supplier pays you for the kilowatt-hours exported, typically between 3 pence and 15 pence per kilowatt-hour, depending on the tariff.

4. Payment is deposited to your account

Payments are usually made monthly or quarterly, depending on your supplier. The money goes directly to your registered bank account.

Feed-in Tariff vs. Smart Export Guarantee

Older solar systems (installed before 2019) may be on the Feed-in Tariff scheme instead of SEG. The difference:

Feed-in Tariff (FIT)

Older scheme (closed to new applicants in 2019). Typically offers higher export rates (around 5–20 pence per kilowatt-hour). Can be transferred to the new owner via the supplier's change-of-ownership process, so notify the supplier promptly to confirm.

Smart Export Guarantee (SEG)

Current scheme (launched 2020). Typically offers lower rates (3–15 pence per kilowatt-hour). Must be registered to you specifically; does not transfer automatically.

Did the previous owner have an export tariff?

When you buy a property with an existing solar system, any SEG or Feed-in Tariff payments are still registered to the previous owner. You need to act quickly to transfer the tariff to your name, or you'll lose the money.

Why you need to act within 30 days

Problem 1: Payments go to the previous owner

The SEG tariff is tied to a specific person and bank account. As long as the registration remains under the previous owner's name, all payments will continue going to their bank account. You'll see zero in your account.

Problem 2: Contracts expire

Most SEG tariffs have a contract period of 1–20 years. If the previous owner's contract is approaching expiry, it may terminate before you've had a chance to claim it. Once expired, you'll have to apply for a new tariff.

Problem 3: You may not have required metering

Some older solar installations don't have a smart meter or export meter. Without one, you can't claim SEG payments at all. Installation takes 2–4 weeks.

How to find out who their supplier was

Contact the previous owner directly

They'll know which energy supplier registered the Smart Export Guarantee tariff. This is usually their main electricity supplier.

Ask your property solicitor

They may have records from the property survey or handover documents. Check the conveyancing paperwork.

Look for SEG statements

Check any paperwork left in the property or ask if the previous owner left documentation about export payments.

Contact your Distribution Network Operator (DNO)

They sometimes have records of SEG registrations. Provide your address and installation date. If this fails, contact major suppliers directly: Octopus, British Gas, E.ON, OVO, or EDF.

How to register for SEG: step by step

1

Find out who the previous owner's SEG supplier was

The previous owner registered their solar system with an energy supplier to receive SEG payments. You need to identify which one. Ask the previous owner directly, check with your solicitor, look for SEG payment statements in the paperwork left in the property, or contact your DNO if all else fails.

2

Check if you have a smart meter or export meter

Most SEG suppliers require proof of export via a smart meter or export meter. Without one, they won't pay you. Look for a smart meter (usually on an outside wall near your fusebox or consumer unit with a digital display), or an export meter (a white box usually mounted directly above or below the consumer unit, often labelled "Export" or "EXP").

If you don't have either: Contact your energy supplier and request a smart meter installation. Most suppliers provide this free for solar homes.

3

Contact the SEG supplier to notify of the property sale

Call the supplier (whose name you found in Step 1) and explain that the property has been sold and you're now the owner. You'll need to provide proof of purchase: a property purchase receipt or completion document from your solicitor, a council tax bill in your name with the property address, or mortgage documents or completion statement.

Tell them your property address, the installation date of the solar system (approximately), and that you're the new owner and want to transfer or reapply for the SEG tariff.

4

Apply for a new SEG tariff in your name

You have two choices: transfer the existing tariff to your name and bank account, or switch to a different supplier for a potentially better rate. Transfer is simpler but keeps you at the same rate (takes 1–2 weeks). Switching requires comparing rates first, and you'll lose the historical tariff with the previous supplier but may gain a better rate (takes 2–4 weeks).

Major suppliers offering SEG: Octopus Energy, British Gas, E.ON, OVO Energy, EDF, Eon Next, Good Energy, Scottish Power.

5

Verify export meter readings and payments

Once the tariff is in your name, confirm that your export meter readings are being submitted to the supplier, you've provided your correct bank account details, and your first payment arrives on schedule (usually monthly or quarterly).

Check your first month's monitoring data (total kilowatt-hours exported) and multiply by your SEG rate. Your payment should be roughly that amount, allowing for meter submission delays.

Which suppliers offer SEG?

Most major UK energy suppliers now offer SEG tariffs, but rates, contract terms, and eligibility vary. Here's what to consider when choosing a supplier and how to compare rates.

Octopus Energy

One of the largest providers of SEG tariffs in the UK. Offers both fixed and tracker rates. Generally competitively priced. Requirements: Smart meter or export meter. Rates: typically 3–10 pence per kilowatt-hour.

British Gas

Major supplier offering SEG for customers with eligible solar systems. Often bundled with gas and electricity packages. Requirements: Smart meter. Rates: typically 4–8 pence per kilowatt-hour.

E.ON

Established SEG provider with a range of tariff options. Part of the E.ON Next suite of renewable products. Requirements: Smart meter. Rates: typically 3–7 pence per kilowatt-hour.

OVO Energy

Growing SEG provider with good rates for smaller systems. Known for customer service. Requirements: Smart meter. Rates: typically 5–12 pence per kilowatt-hour depending on plan.

EDF

Major supplier offering SEG as part of their renewable energy strategy. Competitive rates. Requirements: Smart meter. Rates: typically 4–9 pence per kilowatt-hour.

Good Energy

Independent renewable energy supplier with strong commitment to solar and export payments. Premium rates but higher customer loyalty. Requirements: Smart meter. Rates: typically 6–15 pence per kilowatt-hour depending on time-of-use.

How to compare rates

Check the supplier's website for current SEG rates

Don't rely on old information. Rates change frequently and vary by region and tariff type.

Ask about contract length and rate type

Contract length is usually 1–5 years. Clarify if rates are fixed (locked for the contract period, more predictable) or tracker (changes with wholesale electricity prices, potentially higher earnings but less predictable).

Ask about minimum export threshold and metering

Some suppliers have a minimum export threshold. Confirm what metering they accept (smart meter, export meter, or both).

Get a quote before committing

Always compare rates at the time of switching to ensure you're not losing out. Switching resets your tariff history.

What if you inherited a Feed-in Tariff?

If the solar system was installed before 2019, the previous owner may be on the old Feed-in Tariff (FIT) scheme instead of the newer Smart Export Guarantee. FIT and SEG have different transfer rules and rates.

Feed-in Tariff transfer rules

FIT can transfer to the new owner — but you must notify the supplier

Unlike SEG, Feed-in Tariffs are sometimes tied to the property rather than the individual. Contact the previous owner's supplier to confirm your FIT status and whether it's transferred to your name. You may need to provide proof of property purchase. If payments are not arriving after the transfer, see our guide on FIT payments stopped.

FIT rates are typically higher than SEG

Feed-in Tariffs usually pay 5–20 pence per kilowatt-hour exported, compared to SEG's 3–15 pence. If you inherited a FIT, you're likely in a better position than newer systems.

FIT has a guaranteed term

Feed-in Tariffs come with a guaranteed contract period of 20 or 25 years. Once the term ends, you revert to SEG or have limited export payment options.

You can stay on FIT or switch to SEG

Once the FIT term expires, you must switch to SEG or another export payment scheme. If you switch early, you'll lose the FIT contract and its higher rates. Only consider switching if SEG rates are significantly better, which is rare.

How to confirm you have FIT and not SEG

Contact the previous owner or their supplier

Ask if the system is on Feed-in Tariff (closed to new applicants in 2019) or Smart Export Guarantee (launched 2020). The supplier name and contact details should tell you which scheme.

Check FIT payment statements

Old FIT contracts often show a higher rate (e.g., 8 pence per kilowatt-hour) compared to typical SEG rates. Look for documents showing the Feed-in Tariff scheme name and guaranteed term (usually 20 or 25 years).

Look for a FIT installation report

If the solar installer left paperwork, check for mention of "Feed-in Tariff" or "FIT guarantee." FIT systems are registered with Ofgem and come with official documentation.

Common export payment issues

Even after transferring your tariff, problems can occur. Here are the most common issues and how to solve them.

You don't have a smart meter or export meter

Without metering, the supplier has no way to verify your export and won't pay you. Solution: Contact your energy supplier and request a smart meter installation. Most suppliers provide this free for solar homes. Installation takes 2–4 weeks.

Your tariff wasn't transferred correctly

If the supplier says they can't transfer the previous owner's tariff, you'll need to apply for a new one. This may take 2–4 weeks. Ask if the previous owner's contract has expired or has special conditions that prevent transfer.

You're not receiving payments after the transfer

Payments usually start 4–8 weeks after transfer. If longer, contact the supplier to confirm they have your bank account details, your export meter readings are being submitted, and the tariff is active on your account. Check your first month's monitoring data to estimate expected payment.

The payment is much lower than expected

Low payments can happen if your export meter wasn't installed correctly, your system isn't exporting as much as expected (low generation, high self-consumption), or the supplier is using a lower rate than quoted. Ask your supplier for a breakdown of export readings and check against your monitoring data.

You're missing backpay from before the transfer

Most suppliers won't backdate payments if you transfer mid-contract. This means you'll lose any export payments between the property purchase and the tariff transfer. This is why acting within 30 days is crucial. If you delayed significantly, ask the supplier if they'll make an exception or goodwill payment, but expect a firm no.

When to call a professional

Export payment issues can be complex, especially if the previous owner is uncooperative, the supplier has lost records, or your system has metering problems. If you're stuck after following these steps, professional help can save you time and money.

Your system isn't exporting what it should

If your export payments are very low but monitoring data shows significant export, the issue may be with your system, inverter, or meter. Our remote diagnostic service can identify if the inverter is working correctly and if the export meter is reading accurately.

You can't find the previous owner or supplier

If you've exhausted all options to identify the supplier, we can help you trace records, contact your DNO, or advise on applying for a new tariff from scratch. Book a health check to discuss your situation.

You don't have a smart meter and installation is delayed

Waiting 2–4 weeks for a smart meter costs you money. Our team can liaise with your supplier to expedite installation, or advise on temporary metering solutions while you wait. A solar system health check is the quickest way to explore your options.

Your export meter is faulty or broken

If your export meter is damaged or not recording correctly, the supplier may refuse payment until it's replaced. We can verify meter status and liaise with your supplier or installer to arrange replacement. Contact us via a remote diagnostic booking.

You want to switch to a better SEG rate

Comparing suppliers and understanding contract terms is time-consuming. Our team can review current rates, estimate your annual earnings, and advise whether switching is worthwhile. Book a solar health check to compare your options.

FAQ

Frequently asked questions

No, not directly. SEG tariffs are registered to a specific person and bank account. However, you can contact the supplier and ask to transfer the tariff to your name and bank account. Some suppliers make this straightforward as a "Change of Occupant" request; others require you to close the old tariff and apply for a new one. Either way, you'll need to provide proof of property purchase and your banking details.
It depends on your supplier and tariff, but typical export rates are between 3 pence and 15 pence per kilowatt-hour. A 4 kilowatt system on a sunny day might export 5–10 kilowatt-hours, earning £0.15–£1.50 per day. Over a year, realistic earnings are £100–£400 for a typical system, depending on your location, system size, and how much surplus you generate. Rates fluctuate with wholesale electricity prices and by supplier.
A smart meter is a small white or black box typically mounted on an outside wall near your fusebox or consumer unit. It usually has a digital display showing a digital clock, kilowatt-hour readings, and sometimes separate import and export figures. If you see a meter with a spinning dial and no digital display, that's an old meter and not a smart meter. Contact your electricity supplier if you're not sure—they have records of whether a smart meter has been installed at your address.
Your solicitor may have records from the property conveyancing. Alternatively, contact your DNO (Distribution Network Operator) with your address—they sometimes have records of SEG registrations. You can also contact the major suppliers (Octopus, British Gas, E.ON, OVO, EDF) directly and provide your address and install date to see if any of them have a record. Worst case, you can apply for a new SEG tariff with a supplier of your choice, though you may miss some historical payments.
Contacting the supplier to claim or transfer the tariff takes 10 to 30 minutes, a transfer into your name typically takes 1 to 2 weeks, and switching to a new supplier takes 2 to 4 weeks. First payments usually start 4 to 8 weeks after the transfer completes. If you need a smart meter installed first, allow another 2 to 4 weeks, which is why acting within 30 days of purchase matters.
