Immingham (DN40) sits on the south bank of the Humber in North East Lincolnshire, a town shaped by its docks, the giant Immingham port and the industrial corridor running toward Killingholme. For homeowners here, the heating picture is different from central Grimsby or Cleethorpes: many of the surrounding villages—Habrough, Stallingborough, South Killingholme, East Halton—sit off the mains gas grid, running on oil, LPG or old electric storage heaters. That is exactly where an air source heat pump (ASHP) makes the most financial sense, and it is why demand across the DN40 postcode has climbed sharply into 2026.
YEERS is a Hull-based, MCS-certified installer covering the full 30-mile radius around the Humber, including Immingham and the North East Lincolnshire coast. Every installation carries a 10-year workmanship warranty, and as an MCS-accredited firm we handle the grant paperwork on your behalf.
Why Immingham homes suit air source heat pumps
Three local factors stack in favour of a heat pump here:
- Off-gas villages nearby: If you heat with oil or LPG in the villages ringing Immingham, you are paying some of the highest running costs in the region. A heat pump running at a seasonal efficiency of 300–400% typically undercuts oil and LPG comfortably, and removes the need for a tanker delivery or a bulk fuel order.
- Post-war and modern housing stock: Much of Immingham was built or expanded around the docks in the mid-20th century, giving a large share of 1950s–1970s semis and estate housing with cavity walls that respond well to a correctly sized ASHP once loft and cavity insulation are topped up.
- Northern Powergrid grid capacity: The whole area is served by Northern Powergrid (Yorkshire) as the Distribution Network Operator. Most single-phase homes accept a domestic ASHP without a supply upgrade, and we handle the DNO notification as part of the job.
The coastal factor
Immingham is an exposed, salt-air estuary environment. Wind loading off the Humber and airborne salt can corrode cheap fixings and unprotected units over time. On coastal DN40 installs we specify marine-grade fixings and appropriately protected outdoor units, and position the unit to avoid the worst of the prevailing north-easterly wind—a detail token installers from outside the region routinely miss.
Grants and VAT: what you can claim in 2026
The single biggest lever is the £7,500 Boiler Upgrade Scheme. In England and Wales this grant is paid toward an ASHP or GSHP install, and because YEERS is MCS-certified we claim it directly—it is deducted from your quote rather than something you chase afterwards. On top of that, 0% VAT applies to domestic heat pumps until 31 March 2027 (rising to 5% after), so 2026 is a genuinely favourable window.
| Incentive | Value (2026) | Applies to Immingham? |
|---|---|---|
| Boiler Upgrade Scheme (BUS) | £7,500 off an ASHP/GSHP | Yes — England & Wales, MCS installer claims it |
| 0% VAT on heat pumps | 0% until 31 Mar 2027, then 5% | Yes — UK-wide on domestic installs |
| ECO4 / LA Flex | Council-administered, to 31 Mar 2026 | Via North East Lincolnshire Council — eligibility-based |
Note: batteries are not eligible for the BUS grant, and ECO4 LA Flex is means/eligibility tested through your local authority—we will flag honestly whether you are likely to qualify rather than over-promise.
What a heat pump install looks like in DN40
A typical residential ASHP for an Immingham semi is sized after a room-by-room heat-loss survey—not a rule of thumb. That survey determines the unit size, whether any radiators need upsizing for lower flow temperatures, and where the outdoor unit sits. For most homes the work is completed in a few days. Because Immingham has a large share of similar estate-built properties, we can often draw on comparable local heat-loss data to size accurately first time.
Comparing running costs
For an off-gas home currently on oil or LPG, the switch to a heat pump usually delivers the clearest saving. For a home already on mains gas, savings are more modest and depend on your tariff—pairing the heat pump with a smart electricity tariff and, where relevant, solar makes the numbers work harder. A typical 4kW solar array in this region costs roughly £6,200–£8,200 and generates around 3,400–3,650 kWh a year, some of which can offset heat-pump running costs, with surplus exported under the Smart Export Guarantee (SEG rates currently range from about 1p to 27p, with Octopus among the strongest).
Serving Immingham and the wider Humber
YEERS covers Immingham, Grimsby, Cleethorpes and the surrounding North East Lincolnshire villages, as well as across the estuary into Hull and the East Riding. If you are just outside Immingham, our guide to air source heat pumps in Grimsby covers the neighbouring DN31–DN37 area in more detail. Wherever you are in the 30-mile Humber radius, the same MCS standards, marine-grade coastal specification and 10-year workmanship warranty apply.

Local FAQs
Can I get the £7,500 Boiler Upgrade Scheme grant in Immingham?
Yes. Immingham is in England, so the £7,500 Boiler Upgrade Scheme applies to air source and ground source heat pumps. Because YEERS is MCS-certified, we claim the grant for you and deduct it from your quote rather than you having to reclaim it afterwards.
Are heat pumps worth it for off-gas villages around Immingham?
Usually yes. Homes in villages like Habrough, Stallingborough and South Killingholme that run on oil or LPG tend to see the clearest savings, because a heat pump running at 300–400% efficiency undercuts bulk oil and LPG and removes tanker deliveries. On-gas homes save less, so we assess each property honestly before recommending.
Does the salt air on the Humber affect a heat pump?
It can if the wrong hardware is used. Immingham's exposed estuary location means salt air and wind loading off the Humber. On DN40 coastal installs we specify marine-grade fixings, protected outdoor units and position the unit away from the worst prevailing wind to protect longevity.
Do I need an electricity supply upgrade for a heat pump in Immingham?
Most single-phase Immingham homes accept a domestic air source heat pump without a supply upgrade. The area is served by Northern Powergrid (Yorkshire), and YEERS handles the DNO notification as part of the installation.
Is there 0% VAT on heat pumps in 2026?
Yes. Domestic heat pump installations carry 0% VAT until 31 March 2027, after which the rate rises to 5%. Installing in 2026 secures the full 0% rate on top of any Boiler Upgrade Scheme grant you qualify for.
Can I combine a heat pump with solar panels?
Yes, and it is a popular pairing in North East Lincolnshire. A typical 4kW array costs around £6,200–£8,200 and generates roughly 3,400–3,650 kWh a year in this region, offsetting some heat-pump running costs. Surplus can be exported under the Smart Export Guarantee. Note batteries are not eligible for the BUS grant.
