The Smart Export Guarantee pays North West solar owners 4-7.5p per kWh for excess electricity exported to the grid. Typical Lancashire and Greater Manchester homes earn £200-400 annually from SEG payments, with some suppliers offering premium rates up to 15p per kWh for renewable electricity exports.
If you’re looking into solar panels, you’ve probably heard about the Smart Export Guarantee (SEG) – the scheme that pays you for surplus electricity your panels generate. But what does it actually mean for your bank balance, and how much can you realistically expect to earn from it?
I get a lot of questions about SEG payments, often from people who’ve been told wildly optimistic figures by pushy salespeople, or pessimistic estimates by sceptics who think it’s too good to be true. Let me give you the honest reality of what SEG payments actually look like for typical North West families.
What is the Smart Export Guarantee anyway?
The simple explanation
When your solar panels generate more electricity than your house is using at that moment, the surplus automatically goes back into the National Grid through your electricity meter. Under the Smart Export Guarantee, energy suppliers are required to pay you for this exported electricity.
It’s essentially the government saying “if you’re generating clean electricity that helps the grid, you should get paid for it.” It replaced the old Feed-in Tariff scheme in 2019, though the payments are more modest.
How it actually works in practice
During the day: Your panels generate electricity. Your house uses what it needs immediately (lighting, appliances, whatever’s switched on). Any excess gets exported automatically – you don’t need to do anything.
Your meter records: How much you’ve imported from the grid and how much you’ve exported to it. Smart meters make this automatic.
You get paid: Energy suppliers credit your account (or pay you directly) for the electricity you’ve exported, usually quarterly or annually.
It’s completely automatic once it’s set up. You don’t need to do anything except enjoy the payments.
What are the actual payment rates?
Current SEG rates (as of 2025)
Standard rates: Most suppliers offer 4-6p per kWh exported Better rates: Some competitive suppliers offer 6-7.5p per kWh Premium rates: A few suppliers offer up to 12-15p per kWh (usually with conditions)
For comparison: You typically pay 25-30p per kWh for electricity you import from the grid.
This might seem unfair – you’re paid much less for electricity than you buy it for. But remember, you’re being paid for electricity you don’t actually need at that moment, so it’s essentially “free money” for surplus generation.
Rate variations across suppliers
Octopus Energy: Currently offers some of the best SEG rates, including time-of-use tariffs that pay more during peak hours
British Gas: Standard SEG rates, but simple and reliable payment process
EDF: Competitive rates with good customer service for SEG customers
Local suppliers: Some smaller suppliers offer premium rates to attract solar customers
The rates change regularly, and you can switch SEG supplier without changing your electricity supplier, so it’s worth shopping around.
How much can a typical North West family actually earn?
Real examples from Lancashire and Greater Manchester homes:
Small system (3kW) – typical terraced house:
- Annual export: 800-1,200 kWh
- SEG income at 5p/kWh: £40-60 per year
- Better rate at 7p/kWh: £56-84 per year
Medium system (4kW) – typical family home:
- Annual export: 1,200-1,800 kWh
- SEG income at 5p/kWh: £60-90 per year
- Better rate at 7p/kWh: £84-126 per year
Large system (6kW) – bigger house or lower daytime usage:
- Annual export: 1,800-2,500 kWh
- SEG income at 5p/kWh: £90-125 per year
- Better rate at 7p/kWh: £126-175 per year
Premium rate example (where available):
- Medium system at 12p/kWh: £144-216 per year
What affects how much you export?
Your daytime electricity usage: The more electricity you use during the day when panels are generating, the less you export. Families who are out at work/school typically export more.
System size relative to usage: Bigger systems relative to your consumption export more surplus electricity.
Seasonal patterns: More exports in summer when generation is higher, fewer in winter.
Your lifestyle: Working from home, running washing machines during the day, electric vehicle charging all reduce exports but increase your direct solar savings.
SEG vs using electricity yourself – what’s more valuable?
The maths that matters
Using solar electricity yourself: Saves 25-30p per kWh (the cost of grid electricity) Exporting solar electricity: Earns 4-7.5p per kWh (SEG payment)
Clear winner: Using your solar electricity directly saves you 3-5 times more money than exporting it.
This is why battery storage can be attractive – it lets you store excess electricity for evening use rather than exporting it at lower rates. But batteries add significant cost, so the economics depend on your specific situation.
Smart usage patterns
Some families learn to shift electricity usage to daytime when possible:
- Run washing machines and dishwashers during the day
- Charge electric vehicles from solar during daylight hours
- Use smart timers for pool pumps, immersion heaters, etc.
But don’t stress about this – even if you export lots of electricity, you’re still getting paid for it and making good savings overall.
How do you actually get set up for SEG payments?
What you need
Smart meter: Essential for accurate export measurement. Most new installations include smart meter fitting if you don’t already have one.
MCS certification: Your solar installation must be MCS-certified (all reputable installers provide this automatically).
SEG application: Your installer usually handles this, or you can apply directly to energy suppliers.
Generation meter: Some installations have separate meters just for monitoring generation (different from export measurement).
The application process
Step 1: Installation complete and commissioned Step 2: MCS certificate issued Step 3: SEG application submitted (installer or you can do this) Step 4: Supplier confirms acceptance and payment arrangements Step 5: Start receiving payments (usually within 1-3 months)
Most good installers handle steps 3-4 for you as part of their service.
Different types of SEG tariffs
Fixed rate tariffs
- Rate: Same price per kWh regardless of when you export
- Payments: Usually quarterly, based on meter readings
- Good for: Most domestic solar installations
Time-of-use tariffs
- Rate: Different prices depending on time of day/season
- Peak rates: Higher payments during high-demand periods
- Good for: Larger systems that can export during peak hours
Smart tariffs
- Rate: Variable based on grid demand and wholesale prices
- Potential: Higher returns but more complexity
- Good for: Tech-savvy households who want to optimise
For most North West families, simple fixed-rate tariffs are the easiest option.
Common misconceptions about SEG
Myth: “It’s not worth bothering with small amounts”
Reality: Even £60-100 per year adds up over 25 years – that’s £1,500-2,500 total income from electricity you don’t need anyway.
Myth: “The paperwork is complicated”
Reality: Most installers handle SEG registration as part of their service. Once set up, payments are automatic.
Myth: “You’re locked into your electricity supplier”
Reality: You can choose any SEG supplier regardless of who supplies your electricity, and you can switch SEG suppliers.
Myth: “The rates are too low to make any difference”
Reality: SEG payments are bonus income on top of your main savings from reduced electricity bills. They’re not meant to be huge, but they’re still worthwhile.
Myth: “It’s only temporary”
Reality: SEG is a government scheme designed to support renewable energy. While rates may change, the principle of paying for exports is established policy.
How SEG fits into your overall solar benefits
The complete picture for a typical 4kW North West installation:
Annual electricity bill reduction: £700-900 Annual SEG income: £80-120
Total annual benefit: £780-1,020 Property value increase: £2,500-4,000 (one-time)
SEG typically represents 10-15% of your total solar benefits. It’s a nice bonus rather than the main financial driver.
25-year income projection
SEG payments over system lifetime: £2,000-3,000 Total solar savings over 25 years: £20,000-25,000 SEG as percentage of total benefits: About 10-12%
The main benefit is always the electricity you don’t have to buy from the grid, but SEG provides a useful additional income stream.
Tips for maximising SEG income
Choose your SEG supplier wisely
- Compare rates across different suppliers
- Look for suppliers offering premium rates for solar exports
- Consider time-of-use tariffs if your exports align with peak periods
Don’t obsess over exports vs self-consumption
- Using electricity directly saves more money than exporting it
- But don’t worry about perfectly timing your electricity use
- The system works automatically to maximise your overall benefits
Keep good records
- Monitor your export levels through your solar app
- Keep SEG payment records for tax purposes (though domestic SEG income isn’t taxable)
- Track payments to ensure you’re getting what you’re owed
Consider future developments
- Battery storage can reduce exports but may increase overall savings
- Electric vehicle charging can use more solar directly
- Heat pumps and other electric heating can increase self-consumption
Regional variations across the North West
Grid connection quality
Urban areas (Manchester, Preston): Excellent grid connections, no export limitations Rural Lancashire: Occasionally grid capacity limits on very large installations, but not typical domestic systems
Supplier availability
All major suppliers: Available across Lancashire and Greater Manchester Local suppliers: Some smaller suppliers focus on specific regions Premium rate access: Generally available region-wide
Payment processing
No regional differences: SEG payments work the same way across the North West Meter reading: Smart meters eliminate regional variations in billing
What happens if SEG rates change?
Rate protection
Existing contracts: Usually protected for 12 months minimum Rate changes: Suppliers must give notice before changing rates Switching rights: You can always switch to a better SEG deal
Long-term outlook
Government policy: Strong support for renewable energy exports Rate trends: Likely to improve as grid values clean electricity more highly Technology development: Smart grid developments may create new payment opportunities
The trend is toward better recognition of the value that home solar provides to the grid.
Should SEG income influence your solar decision?
Honest assessment
SEG income is a nice bonus, but it shouldn’t be the deciding factor for getting solar panels. The main financial benefits come from:
- Reduced electricity bills (80-85% of total benefits)
- Property value increase (10-15% of benefits)
- SEG income (5-10% of benefits)
If your solar installation only made financial sense because of SEG payments, it probably doesn’t make sense at all.
Decision framework
Good reasons to get solar: Substantial electricity bill reductions, energy independence, environmental benefits SEG as bonus: Additional income that improves the overall return but isn’t essential Don’t rely on: Optimistic projections of future SEG rate increases
The realistic verdict
SEG payments provide a modest but worthwhile additional income stream for North West solar owners. You’re typically looking at £80-150 per year for a standard family installation – not huge money, but enough to cover a family meal out each quarter.
The beauty of SEG is that it’s completely passive income. Once set up, you get paid for surplus electricity without doing anything. It’s like having a small investment that pays dividends four times a year.
While SEG income shouldn’t be the main reason you get solar panels, it’s a genuine benefit that improves the overall return on your investment and provides a pleasant quarterly reminder that your solar panels are working hard for your family.
