Craigavon, A Planned Town With an Unplanned Energy Story
Craigavon is one of the UK’s few purpose-built new towns, designed in the 1960s to link Portadown and Lurgan into a single urban centre. That planning history matters for you as a homeowner, because it means a huge proportion of the housing stock was built within a relatively short window, mostly between the late 1960s and the 1980s, using the construction methods and insulation standards of that era. Put simply, many homes were built to last, but not to be efficient.
The town sits on a low plateau above Lough Neagh, with areas like Brownlow, Mandeville, and Drumgor designed around the famous network of lakes and green corridors. It’s a genuinely distinctive place. But that open, exposed layout, combined with Northern Ireland’s wet Atlantic climate, means your home is working harder to stay warm than many homes in drier, more sheltered parts of the country.
The good news is that Craigavon’s predominantly semi-detached and detached housing stock is actually well-suited to eco upgrades. Most homes have usable roof space, gardens for potential heat pump plant units, and cavity walls that can often be filled. If you’ve been putting off energy improvements, this guide is here to show you exactly where to start, with numbers specific to homes like yours.

How Energy Efficient Are Craigavon Homes and What Does That Mean for Your Bills
Craigavon homes sit at an average EPC Band C, which is actually above the Northern Ireland average, where Band D remains common, particularly in older rural housing. Across Great Britain, the national average hovers around Band D too, so Craigavon homeowners are starting from a better position than most.
But “above average” doesn’t mean “done.” Band C covers a wide range of actual performance, and many homes in areas like Legahory or the older parts of Brownlow estate are at the lower end of that band. In practical terms, a Band C home in Craigavon is likely spending between £1,400 and £1,900 per year on heating and electricity, and there’s a real chance you could cut that by a third or more with targeted upgrades.
One thing worth noting for Craigavon specifically is that many homes here are not on the gas grid at all. Oil-fired central heating is the norm across much of the town, particularly in the detached homes on the edges towards Lurgan and Portadown. Oil prices are volatile and have been consistently higher per kWh than gas for much of the past decade. If you’re on oil, your heating bills are likely running higher than the figures above, and your options for switching are arguably more interesting than for gas-connected homes.
| EPC Band | Typical Annual Energy Cost | Compared to Craigavon Average |
|---|---|---|
| Band A or B | £700 – £950 | Significantly better |
| Band C (Craigavon average) | £1,400 – £1,900 | Local baseline |
| Band D | £1,900 – £2,400 | Common in older NI housing |
| Band E or below | £2,500 and above | Significant savings available |
Solar Panels on Craigavon Rooftops, More Viable Than You Might Think
A lot of people assume Northern Ireland isn’t worth bothering with for solar. That’s genuinely not true. Craigavon sits at around 54.5 degrees north and receives roughly 1,100 to 1,200 sunshine hours per year, less than southern England, yes, but comparable to parts of Scotland and Wales where solar is absolutely standard. Modern panels are also much more efficient in diffuse light than older models, which matters in a climate where you get plenty of bright but overcast days.
The main local factors to consider are the prevailing westerly winds coming off Lough Neagh, which means roof fixings need to be solid, and the higher rainfall which means panels benefit from a clean once or twice a year to maintain output. Craigavon’s detached and semi-detached homes typically have generous pitched roofs, often south or south-west facing, which is genuinely good news for generation potential.
Here’s what you can realistically expect from a solar installation on a typical Craigavon home in 2026:
| System Size | Typical Install Cost | Annual Generation | Estimated Annual Saving | Payback Period |
|---|---|---|---|---|
| 3kW system | £5,500 – £6,500 | 2,400 – 2,700 kWh | £420 – £520 | 11 – 14 years |
| 4kW system | £6,800 – £8,000 | 3,200 – 3,600 kWh | £540 – £650 | 11 – 13 years |
| 6kW system | £9,500 – £11,500 | 4,700 – 5,200 kWh | £750 – £900 | 11 – 13 years |
Adding a battery storage unit (typically £3,000 – £5,000 installed) significantly improves your savings by letting you use your generated power in the evenings rather than exporting it. For a Craigavon household with average electricity use of 3,300 kWh, a 4kW panel system with a 5kWh battery is a very sensible combination.
Northern Ireland operates under a separate energy framework from Great Britain. The Smart Export Guarantee applies here, meaning your energy supplier should pay you for surplus electricity exported to the grid, check with Power NI or SSE Airtricity for their current export rates.
Heating Systems That Actually Work for Craigavon’s Climate and Housing Types
With so many Craigavon homes on oil heating, this is the section where the biggest decisions, and biggest savings, often lie. The question most homeowners are asking is whether to replace an ageing oil boiler with another oil boiler, or to make the switch to something entirely different.
Here’s an honest comparison for the kinds of homes you’ll find across Brownlow, Mandeville, and the newer estates out towards Lurgan Road:
| Heating System | Typical Install Cost | Annual Running Cost (typical Craigavon home) | Best Suited To |
|---|---|---|---|
| New oil boiler | £2,500 – £4,000 | £1,300 – £1,700 | Homes not yet ready to switch |
| Air source heat pump | £10,000 – £15,000 | £900 – £1,300 | Well-insulated semi-detached or detached |
| Ground source heat pump | £18,000 – £28,000 | £700 – £1,100 | Larger detached with garden space |
| Biomass boiler | £12,000 – £20,000 | £800 – £1,200 | Rural-edge detached with storage space |
Air source heat pumps are the most practical option for most Craigavon semi-detached homes, provided you’ve done your insulation first. Heat pumps work best when your home holds heat well, if you install one in a poorly insulated house, you’ll be disappointed with the running costs.
Ground source heat pumps suit the larger detached homes on the outskirts more than the denser estates closer to the town centre. You need enough garden for either a borehole or a horizontal ground loop, and the higher upfront cost requires a longer payback horizon.
One genuinely Northern Ireland-specific note, the Boiler Replacement Scheme has historically supported transitions away from older, inefficient oil heating. Check with the NI Housing Executive and your energy supplier for the current position in 2026, as funding availability changes year to year.
Where to Start With Insulation in a Craigavon Home
Given that most of Craigavon’s housing was built between the 1960s and 1980s, cavity wall construction is very common. That’s actually good news, cavity wall insulation is one of the cheapest and most effective upgrades you can make, and in many homes it hasn’t been done yet or may need updating.
Here’s a prioritised list for a typical Craigavon semi-detached or detached home:
-
Cavity wall insulation, start here
For most homes in Brownlow, Drumgor, and the Mandeville area, this is the single biggest win. Drilling small holes, injecting insulation, and sealing up takes a day. Cost is typically £500 – £1,200 for a semi-detached, and annual savings can reach £200 – £350. Payback in 2–5 years.
-
Loft insulation top-up
Many older Craigavon homes have some loft insulation but not enough, 270mm is the recommended depth and many homes have less than 100mm. Topping up to the correct depth costs £300 – £600 and saves up to £200 per year. It’s quick, non-disruptive, and often partially funded through NISEP.
-
Floor insulation
Suspended timber floors in older detached homes lose significant heat. Insulating beneath floorboards costs £800 – £1,500 and saves £70 – £120 per year. Worth doing during any renovation work.
-
External wall insulation (EWI) for solid-walled properties
Homes with solid walls, some older stock near the original town core, need EWI or internal wall insulation instead. EWI costs £8,000 – £16,000 for a semi-detached but can save £400 – £600 annually. Given Craigavon’s high rainfall and driving westerly winds, choose a breathable render system designed for exposed NI conditions. The EWI needs to be specified for high-moisture environments, and a marine-grade finish will last significantly longer.
-
Double or triple glazing upgrades
If your windows are single-glazed or have early double glazing from the 1980s, upgrading to modern A-rated or triple-glazed units saves £100 – £180 per year. Costs range from £4,000 – £9,000 for a full house. Given the coastal salt-air influence near Lough Neagh, specify frames with marine-grade hardware to avoid corrosion issues.
Grants and Funding Craigavon Residents Can Actually Get in 2026
Northern Ireland operates its own energy efficiency funding framework, separate from the GB schemes, which actually gives Craigavon homeowners access to some programmes not available to English or Welsh counterparts, but you do need to know where to look.
The NI Sustainable Energy Programme (NISEP)
NISEP is funded by a levy on energy bills and administered through electricity suppliers including Power NI and SSE Airtricity. It funds insulation, heating controls, and sometimes heating system upgrades for eligible households. You don’t need to be on a low income to benefit, the programme covers a range of households. Contact your electricity supplier directly to ask about current NISEP measures available in the Craigavon area.
The Affordable Warmth Scheme
This is targeted at lower-income households and provides grants for heating system replacements, insulation, and energy efficiency improvements. To qualify, your household income generally needs to be below a set threshold and you should own or privately rent your home. The NI Housing Executive manages this, call them on 03448 920 900 or visit your nearest Housing Executive office to start an application. Given that Craigavon has areas of significant deprivation, particularly in some parts of Brownlow, this scheme is genuinely relevant for a good number of local families.
The Boiler Replacement Scheme
Periodically funded through the Department for the Economy, this scheme has supported homeowners in replacing old inefficient oil and solid fuel boilers. Availability varies, so check the NI Direct website or speak to an approved installer for the latest position.
The Great British Insulation Scheme (NI Equivalent)
Northern Ireland runs its own equivalent of GB insulation programmes. Under the current framework, households in lower Council Tax bands (or the NI equivalent rateable value bandings) can access subsidised loft and cavity wall insulation through energy suppliers. This is worth checking even if you think you won’t qualify, the eligibility criteria have broadened considerably.
The Heat Pump Grant (through the NI Renewable Heat Incentive Replacement)
Following the closure of the original RHI scheme, Northern Ireland has been working toward a replacement programme for domestic renewable heat. Check the NI Direct website and the Department for the Economy for the most current position, heat pump support in NI has been through significant change and it’s essential to get up-to-date information before committing to an installation.
Armagh City, Banbridge and Craigavon Borough Council, the local authority covering Craigavon, also has its own climate action commitments. It’s worth checking their website for any local retrofit support initiatives, as councils in NI have increasingly been running community-level energy efficiency programmes alongside the central government schemes.
