Free Boiler Grants in Plymouth (PL1–PL9)ECO4 Eligibility 2026

Yes. Plymouth City Council's Low Carbon City Team operates ECO4 Flex with delivery brokered through Plymouth Energy Community (PEC), a local charity established by PCC and Cooperatives UK in 2013. The Statement of Intent (v1.0, published 26 January 2023, signed by Paul Barnard, Service Director for Strategic Planning and Infrastructure) sets out four routes: Route 1 is gross household income under £31,000; Route 2 is a combination of two of six proxies (LSOA deciles 1-3, Council Tax Support, NICE NG6 cold-vulnerability, free school meals, a PCC-named local scheme, or an energy-supplier / Citizens Advice referral); Route 3 is an NHS/GP-identified cold-home vulnerability with income disregarded. The SoI is standalone — NOT joint with Devon County Council, South Hams DC, West Devon BC, Torbay or Cornwall, which maintain their own SoIs. Plymouth Energy Community: 01752 477067.

Wales & West Utilities (WWU) is the GDN for the South-West, including all PL1-PL9 postcodes — Plymouth is the South-Western anchor of WWU's network, which also covers Devon, Cornwall, Somerset and Gloucestershire. ECO4 covers the new boiler, internal pipework, meter installation and removal of the old system at no cost. The connection from your meter to the WWU gas main is separate, but Plymouth's dense Victorian and post-Blitz street grid means almost every address is already on the gas main and there is nothing extra to pay. The rare off-main cases (typically newer infill plots on the PL6 / PL7 fringes towards the Tamar Valley) range from around £500 for a short distance up to £2,500+ for longer routes. WWU publishes a domestic quotation tool — link from our gas-network section.

Only if it is non-condensing or broken. ECO4 is governed by Ofgem's SAP-modelled efficiency uplift rules — a working A-rated condensing boiler in a Mutley or Peverell terrace will not qualify because the SAP improvement would be too small to score. A 1970s-1990s non-condensing combi or a back boiler behind a tiled gas fire — both still common across PL1 Stonehouse, PL2 Devonport/Keyham/Ford, PL3 Mutley/Mannamead and PL4 St Judes — is the typical qualifying case. The retrofit assessment (PAS 2035) confirms the band uplift before the install is approved.

These are some of Plymouth's highest-impact ECO4 properties. The Plan for Plymouth was Patrick Abercrombie's 1943 reconstruction blueprint — late-1940s and 1950s brick or render-over-brick semi-detached cottages built en masse to replace the bombed-out inner-city terraces. The stock is sound but the cavity insulation is typically poor and many still run on 1990s non-condensing combis or back boilers in the lean-to extensions added in the 1960s. Boiler replacement plus loft top-up and (where applicable) cavity-wall insulation can lift a Plan for Plymouth semi from EPC E to EPC C in a single intervention.

Yes — this is First-Time Central Heating (FTCH), one of the highest-scoring measures under ECO4 because moving from Economy 7 storage heaters to a gas combi typically jumps the EPC two bands in a single intervention. Most PL5 ex-council blocks (and the PL6 Estover / PL7 Plympton estates) are connected to the WWU gas main at the riser even where individual flats are not yet metered for gas. ECO4 covers the boiler, the full radiator set, the pipework and the removal of the existing electric heaters. Expect three to five days on site, with temporary heating provided where needed.

From the eligibility check to a commissioned new boiler, a typical Plymouth job runs five to seven weeks. The eligibility pass takes 49 seconds. The PAS 2035 retrofit assessment is usually booked within ten working days, with surveyors operating across the city centre, Devonport, the outer ring through Crownhill and Plympton, and across the Plym to Plymstock and Hooe. The install itself is two to three days for a standard combi swap — longer for first-time central heating or back-boiler removal because the chimney has to be capped to building-control standards, adding about a day.

ECO4 closes 31 December 2026. After that, the £15 billion Warm Homes Plan takes over from April 2027 — funded by public investment rather than energy-bill levies, and delivered by the new Warm Homes Agency rather than Ofgem (gov.uk Warm Homes Plan, updated 18 March 2026). You may have seen the successor scheme called 'ECO5' online — that name is not used by government and no scheme by that title exists. For Plymouth households, the practical effect is straightforward: if you apply under ECO4 before the 31 December 2026 close, the install is funded under ECO4 even if the engineer's visit happens in early 2027; if you start a fresh application after 1 January 2027, you'll be routed through the Warm Homes Local Grant (WHLG), the Warm Homes Social Housing Fund, or the £7,500 Boiler Upgrade Scheme depending on your tenure and property. Your local council's energy team continues to handle the referral throughout the transition.
