Who it's for Homeowners adding a stove to a living room or open-plan kitchen, owners of rural properties off the gas grid using a back boiler for primary heating, anyone with an open fire wanting to dramatically improve heat output and efficiency, and self-builders specifying solid fuel from first principles. When you need it Any time of year — autumn and winter are our busiest periods, but planning ahead in spring/summer means earlier survey, more design flexibility and faster install slots when demand peaks. Why professional matters Solid fuel done well is one of the most efficient, comforting and resilient heat sources you can put in a home. Done badly, it's a chimney fire, a carbon-monoxide risk, a failed insurance claim and a Building Regulations enforcement notice. HETAS certification is the difference. What it costs to delay ## The real consequences of putting it off Solid fuel mistakes are catastrophic. These are the real consequences of cutting corners: ### Chimney fires Unsuitable or unlined flues, wrong-spec liner gauge, missing seal at the top — all routes to a chimney fire that can destroy a home in minutes. ### Carbon monoxide poisoning Negative pressure, poor draught, undersized air supply — pull combustion gases back into the room. Multiple UK deaths every year from non-compliant stove installs. ### Voided insurance Any stove without a HETAS certificate or Building Control notification will be excluded from a household claim. Period. ### Failed house sale Conveyancing solicitors specifically ask for stove documentation. Without it, sales are renegotiated or fall through. ### Wasted heat & fuel An undersized or poorly fitted stove burns twice the wood for half the heat — and ages out the firebox within a few seasons. ### Common mistakes we fix #### Choosing the stove by looks alone Output rating must match the room. Oversized stoves overheat and damp down — the worst possible combustion condition (smoky, sooty, polluting). #### Skipping the flue liner Existing masonry chimneys rarely meet modern flue requirements. Lining is non-negotiable on virtually every retrofit. #### DIY hearth and surround Building Regs Doc J specifies minimum hearth dimensions, materials and clearances. A cosmetic surround that fails these is a fire risk and an enforcement target. Our Process ## A predictable, engineered process 1. STEP 01 ### Survey & chimney check We inspect the chimney (smoke test, sweep if needed), measure the room, check air supply provision and confirm hearth and clearance requirements. 2. STEP 02 ### Stove specification We recommend the right output (typically 4–8 kW for a living room), DEFRA-approved for smoke-control areas, and from brands with proper UK parts support. 3. STEP 03 ### Quote & lead time Fixed written quote including stove, flue liner, twin-wall (if required), hearth construction, removal, decoration making-good, Building Control notification. 4. STEP 04 ### Installation (typically 1–2 days) Chimney lined or twin-wall fitted, register plate, stove set on hearth, all connections sealed, draught tested, CO alarm fitted. 5. STEP 05 ### Commission, certificate & handover HETAS certificate issued, Building Control notified, owner manual handed over, fuel and lighting demo, first-burn schedule explained for paint-curing. Why it pays off ## Outcomes you can measure ### Up to 80% efficient combustion Modern Ecodesign stoves convert 75–85% of fuel energy to room heat — versus 20–30% from an open fire. ### Real, instant heat 5 kW into a room is real, radiant warmth — perfect for cold snaps when central heating is slow to respond. ### Energy resilience Off-grid heat that doesn't depend on the gas main, electricity or oil delivery — invaluable in storm and power-cut weeks. ### Back-boiler option Specified models can feed up to 8 radiators and a hot water cylinder — primary heating from a single source in remote rural properties. ### Compliant & insurable HETAS certificate + Building Control notification = full insurance cover and protected resale value. ### Clean burn, DEFRA-approved Smoke-control-area approved stoves with secondary and tertiary air systems for very low particulates. The Engineering Detail ## Under the bonnet Solid fuel is engineering, not decoration. Here's the depth behind a Greencore install: ### Wood-burning vs multi-fuel Wood burners are optimised for logs and burn cleanest. Multi-fuel stoves accept logs, smokeless coal and briquettes via a riddling grate — useful in rural off-grid homes burning a mix of fuels through the season. ### Ecodesign 2022 compliance Since January 2022 all new stoves sold in the UK must meet Ecodesign efficiency and emissions limits. We only install Ecodesign-compliant stoves — Stovax, Charnwood, Hunter, Clearview, Hwam, Esse — never grey-import models. ### DEFRA smoke-control areas Most of Darlington and Middlesbrough are in smoke-control areas. We only fit DEFRA-exempt stoves in those zones, allowing legal wood-burning while meeting Clean Air Act requirements. ### Flue strategy Existing masonry chimney: stainless steel 904-grade liner (lifetime warranty) with insulating backfill. No chimney: twin-wall insulated flue up the inside or outside of the building, fully compliant with Doc J clearances. ### Hearth & clearances Doc J specifies minimum hearth size, non-combustible material thickness (12 mm constructional hearth + decorative top), and clearances from combustibles (typically 150–300 mm depending on stove). Every install meets these or exceeds them. ### Air supply Stoves over 5 kW require dedicated air supply (vent or external air kit). Modern airtight homes need external air kits even on smaller stoves to ensure clean combustion and avoid depressurising the room. ### Back-boiler systems A 12–18 kW back-boiler stove can heat 6–10 radiators plus DHW. We design the system with thermal store, heat-leak radiator (safety), and integration with existing oil/gas boiler as backup. ### Maintenance Annual sweep, annual stove service, glass-rope check every 2 years, baffle plate inspection, flue brush. We schedule it all.
