When a family in North Nottinghamshire contacted Wright Renewables, they had one simple goal: eliminate their gas bill and switch to a more sustainable, future proof heating system.
With rising energy costs, aging radiators, and a combi boiler on its last legs, they wanted a smarter solution that would heat their home efficiently all year round and take advantage of new Smart Export Guarantee (SEG) tariffs.
Today, they’ve not only removed gas entirely from their property, but their home now generates, stores, and manages its own power using a combination of solar PV, battery storage, and an air source heat pump.
All installed by their local, trusted engineers at Wright Renewables. This is how we made it happen...
Our design team specified a full package that would deliver all of the couple’s heating and hot water needs — plus cut their electricity bills dramatically.
The result? A smart, quiet, highly efficient system that works with the building - not against it. The heat pump keeps the home warm and the water hot, while the solar system powers appliances, charges the batteries, and exports any surplus back to the grid.
Perhaps the most impressive figure from this installation is the total cost of energy from April to September: just £6.70.
That’s not £6.70 per month - it’s £6.70 across 6 months.
Thanks to long daylight hours, strong solar generation, and smart use of battery storage, the customer’s need for imported electricity dropped to almost nothing. The heat pump operated at extremely high efficiency in the warmer months, and the combination of night-time battery charging and solar self-consumption meant most of their usage was either free or very low-cost.
“We honestly couldn’t believe it,” the homeowner told us. “Every bill felt like a mistake - in a good way!”
For most UK homes, even during spring and summer, standing charges alone can top £15/month. This result proves what’s possible with a carefully designed solar and air source heat pump system, especially when paired with an agile electricity tariff.
It’s not just in summer that the savings shine. The homeowners reported that their total energy bill in January was 50% lower than the same month in the previous year - despite using only electricity this time, rather than a split gas and electric system.
How?
This year-on-year comparison is a powerful indicator of the real-world performance of renewable systems, especially in challenging UK winter conditions.
“We knew it would be more efficient. We just didn’t expect it to be that much cheaper - even in January,” said the customer.
One of the most exciting features of this system is its time-of-use battery strategy.
The Solis inverter has been configured to charge the 10kWh battery bank overnight during the homeowner’s cheaper Economy 7 (E2) tariff. At just 5.5p per kWh, this electricity is stored and used during the following day, replacing expensive daytime grid electricity (typically 25.5p per kWh).
During sunnier months, the solar panels charge the battery for free - but even in winter, the customer benefits from:
This hybrid model of solar + night charging ensures year-round savings, a brilliant example of modern demand-side flexibility in action.
At the time of writing, this customer is signed up to a Smart Export Guarantee (SEG) rate of 10p per kWh, meaning they earn credit for every unit of electricity exported back to the grid.
But Wright Renewables identified an even smarter option: switching to OVO’s SEG tariff, which currently pays 20p per kWh exported - double their current rate.
If the customer exported just 250 kWh/month on average, that would mean an Annual Income of £600:
By switching SEG providers, they could earn an extra £300 per year - further reducing their payback period and increasing the long-term value of their solar system.
“We always advise our customers to review their SEG options - not all providers offer the same rates,” says Lee Rolfe, Managing Director of Wright Renewables.
Using real-life billing data and our system modelling spreadsheet, the estimated savings stack up like this:
That’s over £1,600 in annual savings, plus no need for future gas boiler maintenance or replacements.
And when you factor in OVO’s 20p SEG rate and improved panel performance in summer, the annual benefit could exceed £2,000 in real terms.
