Yes — if you live in LS1–LS29 and either claim a qualifying benefit (Universal Credit, Pension Credit, PIP, ESA, Income Support, Working Tax Credit or Child Tax Credit) with an EPC of band D–G, or your gross household income is under £31,000 via Leeds City Council's December 2024 LA Flex Statement of Intent, you can apply for a 100% free ECO4 boiler replacement. Leeds is on the Northern Gas Networks gas network — NGN's own UK HQ is in LS15.

There are two routes for Leeds households. Pick whichever applies — you don't need both.
Per gov.uk's Energy Company Obligation page, you qualify if you receive any of:
No qualifying benefit? Leeds City Council runs its own referral route through the LA Flex Statement of Intent.
Bottom line: If your address is in LS1–LS29, you claim a qualifying benefit or fall under Leeds City Council's LA Flex criteria, and your EPC is D-G, the eligibility check is a 49-second form.
Leeds has the most distinctive working-class housing stock of any major UK city — and the largest surviving back-to-back terrace population in the country. The 19th-century industrial boom filled Harehills (LS9), Holbeck (LS11), Hunslet (LS10), Beeston (LS11) and Armley (LS12) with two-storey back-to-backs that share a rear wall with the property behind, eliminating through-ventilation and producing chronic damp problems even today. Even after national bans, Leeds kept building back-to-backs into the early 20th century, and tens of thousands are still occupied. Above the back-to-back belt sit the through-terraces of the Victorian middle classes — Headingley (LS6), Hyde Park (LS6), Burley (LS4), Kirkstall (LS5) and the streets above the Headrow — with bay-window fronts, brick rear extensions and (mostly) cavity-wall construction. The third cohort is the post-war and 1960s/70s council estates: Seacroft, Halton Moor, Gipton, Belle Isle and the Leeds Middleton estate (distinct from the FBU HQ in Manchester's Middleton). For ECO4, the back-to-back belt is the city's strongest catchment — the building-fabric uplift from a combined A-rated condensing combi plus loft insulation routinely lifts a Harehills or Holbeck back-to-back from band E or F to band C.

Bottom line: Leeds's mix of pre-1919 and post-war stock is exactly the catchment ECO4 targets. The mandatory PAS 2035 retrofit assessment will confirm the SAP uplift for your specific address.
Northern Gas Networks is the Gas Distribution Network operator for the North-East and Northern Cumbria — that includes every LS1–LS29 postcode.

If your property is already on the gas main — most Leeds addresses are — there is nothing to pay. ECO4 funds the boiler, internal pipework, controls, meter installation, and safe removal of the old system.
Northern Gas Networks's indicative pricing toolBottom line: Almost every Leeds address (LS1–LS29) is already on the Northern Gas Networks gas main, so the connection cost is £0. The rare off-main cases sit on the outer fringes and pay Northern Gas Networks separately for the new connection.
You may have seen the successor scheme called "ECO5" online — there is no ECO5. The government has abolished the Energy Company Obligation model and replaced it with the Warm Homes Plan — a £15 billion programme funded by public investment rather than levies on energy bills. ECO4 still runs until 31 December 2026, so Leeds households should apply now while the scheme is open.
Low-income grants

Warm Homes Social Housing Fund + Local Grant

per household, clean-heat grant
Delivery moves from Ofgem to a new Warm Homes Agency, with the Social Housing Fund and Local Grant consolidating into a single low-income capital scheme by 2027/28.
Sources: gov.uk — Warm Homes Plan (updated 18 March 2026); Ofgem response to the Warm Homes Plan.
Bottom line: ECO4 closes 31 December 2026. The Warm Homes Plan replaces it from 2027 — apply now while the current scheme is still open and the £4,000–£8,000 install value is fully funded.
Property
Pre-1919 back-to-back terrace, two-storey, two-bed, solid-wall front and rear (no through-ventilation)
Existing system
EPC band E — late-1990s non-condensing combi at end of life, single-zone Y-plan controls, no TRVs, chronic rising damp on the shared rear wall
Measure installed
Old combi removed; new A-rated condensing combi sited in the kitchen; full system flush; new programmable controls and TRVs; loft topped up to 270mm; internal damp-proof course remediation flagged for separate works (not ECO4-funded). Solid-wall insulation scoped as a phase-2 PAS 2035 measure.
Outcome
EPC modelled uplift from band E to band D; first-winter heating-bill cut of roughly £550–£750. £0 paid by the household.
Time on site
Completed in a single day on site.
Illustrative — based on typical LS1–LS29 installs, not a single named customer.
Bottom line: Typical Leeds installs deliver a two-band EPC uplift in a single intervention at £0 to the qualifying household. Your individual case depends on the PAS 2035 assessment, but the LS9 Harehills pattern above is representative.
Total install value typically £4,000–£8,000.
Most Leeds addresses are already on the gas main — nothing extra to pay.
Bottom line: If your ECO4 application is approved, the install is £0 — typical install value £4,000–£8,000. The only out-of-pocket case is a brand-new gas-main connection from off-grid, which is uncommon in Leeds.

Leeds homeowners (EPC band D–G) and private tenants (EPC band E–G, with landlord consent) whose household either claims a qualifying benefit (Universal Credit, Pension Credit, PIP, ESA, Income Support, Working Tax Credit or Child Tax Credit) or has gross income under £31,000 via Leeds City Council's December 2024 LA Flex Statement of Intent. A cold-sensitive health condition or a deprivation-index proxy can substitute for the income test.
Yes. Leeds City Council published its current Statement of Intent on 23 December 2024, covering both ECO4 Flex and the Great British Insulation Scheme. It uses the standard £31,000 income threshold as the primary route, with deprivation-index proxy routes and cold-home vulnerability indicators alongside. Referrals are processed via the council's housing-strategy team.
Northern Gas Networks (NGN) operates the gas mains across all LS postcodes — and NGN's own UK headquarters is in LS15 Leeds. NGN is the GDN for the North East, Northern Cumbria and most of Yorkshire (including Bradford and Hull). ECO4 covers the new boiler, internal pipework, meter installation and removal of the old system at no cost. The connection from your meter back to the NGN main is separate — NGN has a quote tool for households needing a new connection.
Leeds has the largest surviving stock of Victorian back-to-back terraces in the UK — thousands of them are still occupied across Harehills, Holbeck, Beeston, Hunslet and Armley. The strongest scoring measure is an A-rated condensing combi replacement plus loft insulation top-up to 270mm. Solid-wall insulation is in scope as a phase-2 measure but needs a PAS 2035 fabric assessment because of the no-through-ventilation construction. Internal damp-proof remediation is not ECO4-funded.
Often yes. The Victorian and Edwardian through-terraces in Headingley (LS6), Hyde Park (LS6), Burley (LS4) and Kirkstall (LS5) typically combine a solid-brick front with a cavity rear extension. They scored well for combined boiler-replacement plus loft top-up and (where the rear is cavity-built) cavity-wall fill. Leeds' large student-let private rented sector around the University and Beckett means landlord consent is often the slowest step in this catchment.
Often yes — this is First-Time Central Heating (FTCH), and it is 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. Seacroft, Halton Moor, Gipton, Belle Isle and the Leeds Middleton estate were all built to early Parker Morris standards with cavity walls. ECO4 covers the boiler, the full radiator set, the pipework and the removal of the existing electric heaters.
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 Leeds 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.
