Yes — if you live in TS1–TS8 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 Middlesbrough Council's LA Flex route, you can apply for a 100% free ECO4 boiler replacement. Middlesbrough is on the Northern Gas Networks gas grid — the same GDN that serves Newcastle, Sunderland, Hull and the wider North East.

There are two routes for Middlesbrough 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? Middlesbrough Council runs its own referral route through the LA Flex Statement of Intent.
Bottom line: If your address is in TS1–TS8, you claim a qualifying benefit or fall under Middlesbrough Council's LA Flex criteria, and your EPC is D-G, the eligibility check is a 49-second form.
Middlesbrough is one of England's youngest cities — a planned ironworks-and-railway boomtown that grew from a handful of farms in 1830 to over 90,000 people by 1900. The dense Victorian terrace cohort fills Gresham (TS1), North Ormesby (TS3), Pallister Park (TS3) and parts of Newport (TS1) — typically two-up two-down brick terraces built for the Bolckow Vaughan ironworks and the Tees docks workforce, with slate roofs, original timber floors and cellars. Much of the original "Jewel Streets" grid behind Borough Road (named after gemstones — Diamond, Garnet, Emerald) has been cleared since the 1960s, but the surviving streets remain Middlesbrough's primary ECO4 catchment. The post-war picture adds large Middlesbrough Council estates at Grove Hill (TS4), Whinney Banks (TS5), Hemlington (TS8), Pallister Park (TS3) and Coulby Newham (TS8) — typically inter-war and 1960s/70s housing, mostly cavity-walled, with significant amounts of non-traditional construction. The leafier outer suburbs — Acklam (TS5), Linthorpe (TS5), Marton (TS7) — are largely owner-occupied 1930s and post-war semis with higher EPC bands. For ECO4 the strongest catchment is the Gresham / North Ormesby / Grove Hill belt where boiler-replacement-plus-loft routinely lifts EPC band E to band C.

Bottom line: Middlesbrough'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 TS1–TS8 postcode.

If your property is already on the gas main — most Middlesbrough 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 Middlesbrough address (TS1–TS8) 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 Middlesbrough households should apply now while the scheme is open.

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.

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.

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; rear-extension cavity walls drilled and filled.
Outcome
EPC modelled uplift from band E to band C; first-winter heating-bill cut of roughly £550–£750. £0 paid by the household.
Time on site
Boiler swap and cavity-fill completed across two days on site.
Illustrative — based on typical TS1–TS8 installs, not a single named customer.
Bottom line: Typical Middlesbrough 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 TS3 North Ormesby pattern above is representative.
Total install value typically £4,000–£8,000.
Most Middlesbrough 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 Middlesbrough.

Middlesbrough 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 Middlesbrough Council's LA Flex referral. A cold-sensitive health condition can substitute for the income test.
Yes. Middlesbrough Council operates ECO4 Flex referrals via the council's housing and energy team. The standard £31,000 gross income threshold is supplemented by cold-home vulnerability indicators across the four Ofgem Route 2 proxies.
Northern Gas Networks (NGN) operates the gas mains across all TS1–TS8 postcodes — the same GDN that covers Newcastle, Sunderland, Hull and the wider North East and Yorkshire. 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 publishes an online quote tool for households needing a new connection.
Gresham (TS1), North Ormesby (TS3) and the surviving streets around Pallister Park hold Middlesbrough's densest pre-1919 ironworks-era terrace stock. The strongest scoring ECO4 package is an A-rated condensing combi replacement plus loft top-up to 270mm and rear-extension cavity-wall fill where present. Much of the original Jewel Streets grid behind Borough Road has been cleared since the 1960s, but the surviving stock around it remains a primary catchment.
Often yes, but with extra survey steps for the non-traditional-construction stock. Middlesbrough's post-war estates at Pallister Park, Hemlington, Coulby Newham, Whinney Banks and Berwick Hills include significant amounts of Wimpey No-Fines and steel-frame construction. A PAS 2035 retrofit assessment is required before fabric measures can be scoped, but boiler-replacement and First-Time Central Heating are routine and score heavily.
Middlesbrough is one of England's youngest cities — it grew from a handful of farms in 1830 to over 90,000 people by 1900, driven by the Bolckow Vaughan ironworks and the Tees docks. The resulting housing stock is almost entirely Victorian-or-later, with a famously dense central terrace grid (the Jewel Streets) and large planned 20th-century council estates pushed to the outer southern fringe. There's very little pre-1830 building, which simplifies retrofit planning — almost nothing is listed or in a Conservation Area.
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 Middlesbrough 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.
