Yes — if you live in AB10–AB25 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 you sit inside Aberdeen City Council's LA Flex route via SIMD data zones 1–3, low-income Council Tax Reduction or a NICE cold-home vulnerability indicator, you can apply for a 100% free ECO4 boiler replacement. Aberdeen is on the SGN gas network and the parallel Home Energy Scotland route is also worth checking (freephone 0808 808 2282).

There are two routes for Aberdeen 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? Aberdeen City Council runs its own referral route through the LA Flex Statement of Intent.
Bottom line —If your address is in AB10–AB25, you claim a qualifying benefit or fall under Aberdeen City Council's LA Flex criteria, and your EPC is D–G, the eligibility check is a 49-second form.
Aberdeen — the Granite City — has a housing profile shaped by two distinct cohorts. The first is the Victorian and Edwardian granite tenement and terrace stock that fills Rosemount (AB25), Mannofield (AB15), Ferryhill (AB11), Old Aberdeen (AB24) and the inner West End. These are solid-wall, four-storey closes built from local Rubislaw or Kemnay granite, originally heated by open coal fires and later retrofitted — patchily — with non-condensing combi boilers in the 1990s and 2000s. The second cohort is the large post-war local-authority schemes: Mastrick and Northfield (AB16), Tillydrone and Seaton (AB24), Torry (AB11), Kincorth (AB12) and the more recent Bridge of Don developments (AB21–AB22). Many of these blocks were built to early Parker Morris standards and still hold Economy 7 storage heaters where mains-gas extensions never reached the individual flat. Aberdeen also experiences one of the coldest urban climates in mainland UK — roughly 2,200 heating degree days a year, around 20–30% above the England-and-Wales average — which means the £-per-year uplift from a boiler-replacement or First-Time Central Heating ECO4 measure runs higher here than in most southern cities.

Bottom line —Aberdeen'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.

If your property is already on the gas main — most Aberdeen addresses are — there is nothing to pay. ECO4 funds the boiler, internal pipework, controls, meter installation, and safe removal of the old system.
SGN's indicative pricing toolBottom line —Almost every Aberdeen address (AB10–AB25) is already on the SGN gas main, so the connection cost is £0. The rare off-main cases sit on the outer fringes and pay SGN separately for the new connection.
Home Energy Scotland is the Scottish Government's free advice service (freephone 0808 808 2282) and administers Warmer Homes Scotland — a separate, parallel grant scheme. Aberdeen households should normally check ECO4 eligibility first (boiler replacement is the faster route) and use Warmer Homes Scotland as the fallback if they don't meet the ECO4 benefit or LA Flex tests.
Home Energy ScotlandBottom line —Home Energy Scotland runs in parallel with ECO4 — the eligibility tests are independent, so check both before you decide which to apply for first.
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 Aberdeen 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. The Scottish allocation comes through Barnett Consequentials and continues to flow via Home Energy Scotland / Warmer Homes Scotland.

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 granite tenement, top-floor two-bed flat in a shared close of eight flats
Existing system
EPC band E — 1998 non-condensing gas combi at end of life, Y-plan controls, no thermostatic radiator valves
Measure installed
Old combi removed; new A-rated condensing combi sited in the kitchen, full system flush, fresh flue route assessed under PAS 2035 to clear the shared close and neighbouring openable windows, new programmable controls and TRVs
Outcome
EPC modelled uplift from band E to band C; first-winter gas demand cut by roughly a fifth — equivalent to ~£500–£700/yr at typical Aberdeen exposure. £0 paid by the household (qualifying benefit + EPC band E SAP improvement trigger).
Time on site
One day on site once the flue route and parts were signed off (about a half-day longer than a freestanding-house swap because of access through the close).
Illustrative — based on typical AB10–AB25 installs, not a single named customer.
Bottom line —Typical Aberdeen 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 AB25 Rosemount pattern above is representative.
Total install value typically £4,000–£8,000.
Most Aberdeen 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 Aberdeen.

Aberdeen homeowners and private tenants whose home is EPC band D–G and whose household either (a) claims a qualifying benefit such as Universal Credit, Pension Credit, PIP, ESA, Income Support, Working Tax Credit or Child Tax Credit, or (b) sits within Aberdeen City Council's LA Flex route — Scottish Index of Multiple Deprivation 2020 data zones 1–3, receipt of Council Tax Reduction on low-income grounds, or a NICE cold-home vulnerability indicator (cardiovascular, respiratory, limited-mobility, immunosuppressed or specified clinical conditions).
ECO4 is the UK-wide scheme funded by energy suppliers and delivered by accredited installers (with LA Flex referrals from Aberdeen City Council where applicable). Home Energy Scotland (freephone 0808 808 2282) is the Scottish Government's free advice service and administers Warmer Homes Scotland — a separate, parallel grant. Aberdeen households can be eligible for one, both, or neither: the routes are independent. The pragmatic order is normally an ECO4 check first because the boiler-replacement uplift is faster, with Warmer Homes Scotland as the fallback where ECO4's benefit and LA Flex tests are not met.
SGN (Scotland Gas Networks) is the GDN for every AB10–AB25 postcode. ECO4 covers the new boiler, internal pipework, the meter installation and removal of the old system at no cost. The connection from your meter to the SGN main is separate — for a standard connection where the meter is within 20 metres of an existing main, SGN's published service charge is around £893 plus VAT, with longer runs costing more. SGN publishes a quick-estimate tool and a Scotland service-charges document so you can check the figure before applying.
Yes, though flueing is the part that takes the most planning. Aberdeen's four-storey granite closes — especially top-floor flats in Rosemount (AB25), Mannofield (AB15) and Ferryhill (AB11) — typically share a close with six or eight flats, and the original flue may run through a shared chase. Building-control rules require the new condensing flue to terminate clear of openable windows and shared light wells. The PAS 2035 retrofit assessment under ECO4 includes a flue-route survey, and the install often takes a half-day longer than a freestanding house because access through the close has to be coordinated.
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. Most ex-council blocks in AB16, AB24 and AB21 are connected to the SGN mains even where individual flats are not yet hooked up. ECO4 covers the boiler, the full radiator set, the pipework and the removal of the existing electric heaters. Works typically take three to five days on site and temporary heating is provided where needed.
Yes. Aberdeen experiences roughly 2,200 heating degree days a year, around 20–30% above the England-and-Wales average. That means the same boiler upgrade delivers a larger £-per-year cut here than in most southern cities. For a Rosemount granite tenement moving from a 25-year-old non-condensing combi to a new A-rated condensing combi, the modelled first-winter gas saving is typically £500–£700 — meaningfully higher than the equivalent install in, say, Brighton or Plymouth.
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 Aberdeen 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.
