Fully funded insulation for Clacton-on-Sea — CO15 and CO16 retrofits for coastal homes

A fair chunk of the older Jaywick and St Osyth stock was built as seasonal chalets and is now permanent housing — single-skin brick or timber-frame walls, thin floors and tired lofts. The right fix is external wall insulation (EWI), which adds around 90mm of insulation and a new render finish outside the existing wall. That lifts EPCs by one or two bands and typically saves £400-£800 a year on heating. For timber-chalet homes we use a breathable build-up to protect the existing frame. ECO4 funds the full install for eligible households, and Loft insulation and draught-proofing are almost always part of the same package.

For most off-gas coastal properties, yes. Oil prices are volatile and modern air-source heat pumps run at 300-400% efficiency, so a typical 3-bed in St Osyth or Thorpe can save £600-£1,200 a year switching from oil. The Boiler Upgrade Scheme pays £7,500 off the install regardless of income, which brings a typical installed cost down to £4,000-£7,000 depending on heat loss. We do a full heat loss calculation at the survey, spec radiators properly and weatherproof outdoor units against the salt air common along the Tendring coast. Installation is 2-3 days on site with a 3-4 week wait for BUS paperwork.

Yes, and bungalows are often ideal for solar. Low-pitch roofs with clear southerly or easterly aspects are common across Holland, Kirby Cross and Walton, and there are usually no planning complications outside conservation areas. A typical 4 kWp array on a Holland-on-Sea bungalow generates around 4,100-4,300 kWh/year. Pair it with a 5 kWh battery and you can push self-consumption to 70-85%, with Smart Export Guarantee paying around 15p/kWh for exported surplus. We weatherproof all mounting hardware for coastal exposure — stainless fixings, marine-grade seals and sealed cable routes — so you don't get corrosion issues five years in.

Two main routes. ECO4 covers homeowners and private tenants who receive a qualifying benefit (Universal Credit, Pension Credit, Income Support, ESA, Housing Benefit and others) and live in a property rated EPC D-G. Both pay for cavity wall, loft or solid wall insulation in full. Book a free survey on 0800 229 4094 — we run the EPC, benefit and council tax checks on the visit and submit all paperwork on your behalf. You sign one consent form and we handle the rest.

Depends heavily on the starting point. A standard Clacton 1950s cavity-walled semi with an uninsulated loft saves roughly £300-£500 a year after a full ECO4 insulation package. A solid-walled Jaywick bungalow with EWI saves £500-£900 a year and usually lifts the EPC by two bands. An off-gas St Osyth property switching from oil to a heat pump saves £600-£1,200 a year on heating. Adding solar plus a 5 kWh battery layers on another £400-£700 a year regardless of insulation spec. Your surveyor models the specific numbers for your property at the free survey so you see exactly what's on the table before you commit.
