Fully funded insulation and heat pumps across Lowestoft — NR32 and NR33 coastal retrofits

Central Lowestoft terraces are almost all pre-1900 solid-brick construction with no cavity, so the route is solid wall insulation — either external (EWI) or internal (IWI). EWI bonds around 90mm of insulation plus a render finish onto the outside of the wall and delivers the biggest thermal gain, but it changes the external appearance, which matters in Lowestoft's conservation areas — we'll handle planning on your behalf. IWI is a better fit for listed or conservation frontages, using a breathable slim build-up internally. ECO4 funds the full install for eligible households. Typical Victorian terrace savings run £400-£800 a year and the EPC usually lifts two bands. Installation takes 5-10 working days on site.

A lot of it, yes. GBIS covers most EPC D-G homes in council tax bands A-D without the benefit test, which catches a big slice of Oulton Broad semis and terraces. The scheme pays for cavity wall insulation (on the post-1920 stock) or loft insulation in full — no benefit test, no income check. If you're a bit further up the council tax bands, ECO4 is still open to you if you or someone in the household receives a qualifying benefit. We run both checks at the free survey: EPC pulled from the register, council tax band confirmed and benefit eligibility walked through properly. You sign one consent and we handle every bit of the grant paperwork.

Yes, and Lowestoft gets more sunshine than most of the UK. Suffolk's east coast clocks around 1,040-1,090 kWh/kWp a year — comparable to the south coast and well above the national average. A typical 4 kWp Lowestoft array generates 4,150-4,350 kWh/year. Pair it with a 5 kWh battery to push self-consumption to 70-85% and Smart Export Guarantee tariffs pay around 15p/kWh for the surplus you send back. Payback on an unsubsidised install typically runs 6-9 years, and the panels carry 25-year performance guarantees. We use coastal-grade mounting hardware so you don't get corrosion issues in five years.

Yes — off-gas Broads-edge properties are where heat pumps deliver their best payback. An average oil-heated 3-bed in Somerleyton or Lound spends £2,000-£3,500 a year on heating; a well-specced air-source heat pump running at 300-400% efficiency typically cuts that by £600-£1,200. The Boiler Upgrade Scheme pays £7,500 off the install regardless of income, which brings typical installed cost to £4,000-£7,000. We do a full MCS heat loss calc at the survey, uprate radiators properly where needed and weatherproof the outdoor unit for coastal exposure. Installation is 2-3 days on site with a 3-4 week BUS approval wait.

Our own directly-employed teams, every install. We don't subcontract. The surveyor who scopes your Lowestoft property briefs the installer face to face, and one project coordinator stays with you from first call through sign-off. That's how we deliver consistent quality across 2,500+ installs and stand behind the 25-year product guarantees and 5-year workmanship cover. You get one named contact and one phone number for the whole job — no runaround, no call-centre loop, no handoffs between three different companies. If something's not right after handover, the same team comes back and sorts it.
