Log Burner in a Shed — UK 2026 Cost Guide
A compliant installation may be possible, subject to the shed’s construction, use, location and the national approval route. UK 2026 indicative professional cost: £3,000–£4,600.
The short answer
UK 2026 typical: £3,000–£4,600 total for a professionally installed shed log burner. Do not assume a packaged “shed kit” makes DIY work compliant: notification, commissioning evidence and insurer requirements depend on the property and jurisdiction.
The popular myth that “sheds are unregulated” for solid-fuel appliances is incorrect. England and Wales publish separate Approved Documents J; Scotland and Northern Ireland use different building-standard systems.

Pick “Shed” on step 5 of the calculator. The scenario multiplier accounts for the smaller building, shorter flue runs, and standard HETAS scope.
Open the calculatorWhat you’re paying for
- Stove unit: micro/tiny stoves (Hobbit, Salamander, Charnwood Aire 3) start £450–£995 and are well-matched to typical shed volumes
- Twin-wall flue (short run): £900–£1,800 installed for a typical single-storey shed flue route
- Hearth + register/floor plate: £250–£600. Often a constructional hearth on a concrete pad, since the shed floor is typically combustible timber
- Fire-rated wall boarding behind and beside the stove (calcium silicate board): £200–£600 in materials and fitting
- HETAS labour: 1 day for a typical single-storey shed setup, less if the building is brand new and the installer can specify positions in advance
The 2.3m adjacent-building check
Under England’s Approved Document J Diagram 17, an outlet within 2.3m horizontally of an adjacent building should be at least 600mm above every part of that building within the same distance. Its clearances from the shed roof and nearby openings also apply.
Measure from the proposed outlet: the gap between the shed and house alone does not determine the answer. A nearby two-storey house can force a substantially taller and more expensive flue. Wales has separate guidance; Scotland and Northern Ireland use their own standards.
Installer and approval route
In England and Wales, an appropriately registered HETAS business may be able to self-certify eligible work through the competent person scheme; otherwise use building control. Scotland uses local-authority building standards, and Northern Ireland uses district-council building control. Confirm that your installer is competent for the proposed appliance, flue and combustible shed construction.
Recommended shed stoves
Right-size the stove to the shed volume. Under-rate rather than over-rate — sheds heat up fast.
- Salamander Hobbit (~£449, 3.5kW) — the archetypal compact UK stove for sheds and shepherd’s huts.
- Charnwood Country 4 BLU (£994, 4kW) — best UK-made entry. 10-year warranty when registered. Charnwood guide →
- Aarrow Hamlet Solution 4 (£695, 4.5kW multifuel) — affordable mid-market option. Aarrow guide →

Can I really put a log burner in a shed?
Potentially, subject to the building’s use and the rules where it is located. Approved Document J is the route in England or Wales; Scotland and Northern Ireland use different building standards. HETAS self-certification can apply to eligible work in England and Wales only, so confirm planning and building-control requirements before buying a stove.
How much does a shed log burner install cost?
UK 2026 estimates run around £3,000–£4,600 professionally installed, but the approval evidence differs by nation. HETAS Competent Person Scheme certification applies to eligible work in England and Wales; Scotland and Northern Ireland use their own building-control records. Flue routing and nearby buildings are major cost variables.
What’s the smallest log burner I can fit in a shed?
The Salamander Hobbit (3.5kW) at ~£449 is purpose-built for compact spaces like sheds, shepherd’s huts, and tiny homes. Other options: Charnwood Country 4 BLU (£994, 4kW) and Aarrow Hamlet Solution 4 (£695, 4.5kW). Going under 5kW keeps you below the air-vent threshold.
Will my shed insurance cover a log burner?
Ask the insurer before installing it. In England and Wales, a HETAS certificate can evidence eligible work notified through the Competent Person Scheme. Scotland and Northern Ireland use different approval records. Coverage depends on the policy terms and the installation evidence the insurer requests.
Do I need a CO alarm in a shed install?
A suitable BS EN 50291 CO alarm should be provided with a new fixed stove. England and Wales cover this in their separate Approved Documents J, Scotland in its Technical Handbook and Northern Ireland in Technical Booklet L. Follow the applicable guidance and the alarm manufacturer’s siting instructions.
