Who it's for Homeowners adding a feature stove to a living room, snug or open-plan kitchen, owners of rural and off-grid properties wanting reliable wood heat, period-property owners reinstating a working fireplace, and self-builders specifying a stove from first principles. When you need it Any time of year — we install year-round, but surveying in spring and summer means earlier slots, more flue and hearth design freedom, and the stove ready well before the first cold snap. Why professional matters A wood burner 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 CO risk and a void on your household insurance. HETAS certification, the right liner spec and Doc J hearth detailing are the difference. What it costs to delay ## The real consequences of putting it off Wood burner mistakes are catastrophic, not cosmetic. Here is what cutting corners actually costs: ### Chimney fires Unlined or wrongly lined flues, missing top seal and tar build-up from wet wood are the leading causes of stove-related house fires across the UK. ### Carbon monoxide poisoning Poor draught, undersized air supply or a stove fitted in a depressurised airtight home pulls combustion gases back into the room — CO is colourless, odourless and kills. ### Voided household insurance Any wood burner without a HETAS certificate or Building Control notification is excluded from a household claim. Even unrelated claims can be challenged. ### Failed house sale Conveyancing solicitors specifically request the HETAS certificate and Building Control notice. Without them, sales stall or get renegotiated against you. ### Wasted fuel and heat A wrongly sized or poorly fitted stove burns twice the wood for half the warmth, glazes the glass black and shortens firebox life dramatically. ### Common mistakes we fix Choosing the stove by looks aloneOutput rating must match the room. Oversized stoves get damped down to avoid overheating — the worst possible combustion (smoky, sooty, tar-laden flue). Skipping the flue linerExisting masonry chimneys rarely meet modern flue requirements. A 904-grade stainless liner with insulating backfill is non-negotiable on virtually every retrofit. DIY hearth and surroundDoc J specifies minimum hearth dimensions, non-combustible thickness and clearances from combustibles. A cosmetic surround that fails these is a fire risk and an enforcement target. Our Process ## A predictable, engineered process - STEP 01 ### Survey & chimney check We inspect the chimney (smoke test and sweep if required), measure the room, check air supply provision, and confirm hearth and clearance requirements before quoting anything. - STEP 02 ### Stove specification We recommend the right output (typically 4–8 kW for a living room), DEFRA-exempt for smoke-control areas, and from brands with proper UK parts and warranty support — Stovax, Charnwood, Hunter, Clearview. - STEP 03 ### Fixed written quote Itemised quote including the stove, flue liner or twin-wall system, hearth, register plate, decoration making-good, CO alarm, HETAS certificate and Building Control notification. - STEP 04 ### Installation (typically 1–2 days) Chimney lined or twin-wall installed, register plate sealed, stove set on hearth, all connections tested, draught checked, CO alarm fitted and commissioned. - STEP 05 ### Certificate & handover HETAS certificate issued, Building Control notified, owner manual handed over, first-burn (paint-curing) and lighting demo, and recommended sweep and service schedule explained. Why it pays off ## Outcomes you can measure ### Up to 85% efficient combustion Modern Ecodesign wood burners convert 75–85% of fuel energy into useful room heat — versus 20–30% from an open fire. ### Real, radiant warmth 5 kW into a living room is instant, radiant heat — perfect for cold snaps when the central heating is slow to respond. ### Energy resilience Heat that doesn't depend on the gas main, electricity or oil delivery — invaluable in storm weeks and power cuts. ### Compliant & insurable HETAS certificate plus Building Control notification means full insurance cover and a protected resale value. ### DEFRA-approved clean burn Smoke-control-area approved stoves with secondary and tertiary air systems for very low particulate emissions. ### Feature for the room A correctly sized and detailed stove becomes the focal point of the room — properly proportioned hearth, neat flue and a glass that actually stays clean. The Engineering Detail ## Under the bonnet A wood burner is engineering, not decoration. Here is the depth behind a Greencore install: ### Ecodesign 2022 compliance Since January 2022 every new stove sold in the UK must meet Ecodesign efficiency and emissions limits. We only install Ecodesign-compliant stoves from established UK-supported brands — never grey-import models with no parts pipeline. ### DEFRA smoke-control areas Most of Darlington, Middlesbrough and the urban North Yorkshire sits inside smoke-control areas. We only fit DEFRA-exempt stoves in those zones — allowing legal wood-burning under the Clean Air Act. ### Flue strategy Existing masonry chimney: 904-grade stainless steel liner (lifetime warranty) with insulating vermiculite or rockwool backfill. No chimney: twin-wall insulated flue routed internally or externally, fully compliant with Doc J clearances. ### Hearth & clearances (Doc J) Doc J specifies a 12 mm constructional hearth, decorative top, minimum hearth size and clearances to combustibles (typically 150–300 mm depending on stove). Every install meets or exceeds these. ### Air supply Stoves over 5 kW require dedicated air supply (vent or external air kit). Modern airtight homes need an external air kit even on smaller stoves to ensure clean combustion and avoid depressurising the room. ### Fuel quality Only kiln-dried hardwood below 20% moisture should ever go into a modern stove. Wet wood is the single biggest cause of glazed glass, tarred liners and chimney fires. We brief every customer on fuel and storage at handover. ### Maintenance schedule Annual chimney sweep, annual stove service, glass-rope check every 2 years, baffle plate inspection. We can arrange the sweep alongside the service to keep the certificate trail clean.
