How to Get Your Log Burner for Less
A log burner is one of those satisfying home improvements that pays for itself in comfort. Here is how to keep the cost down.
Get at least 3 quotes from HETAS registered installers
Log burner installation costs vary significantly depending on chimney condition, liner type, and hearth requirements. Getting three quotes from HETAS registered installers lets you compare what each includes — some bundle the liner and hearth, others charge separately. Written quotes also confirm the installer has surveyed your specific chimney.
Buy the stove yourself and pay for fitting separately
HETAS installers often mark up the stove price. Buying your own stove online or from a showroom sale can save £200–£500. Check with the installer first - most are happy to fit a customer-supplied stove, though some may not warranty the installation against stove faults.
Book during spring and summer when demand is lowest
Most people think about log burners when it gets cold, which means autumn is peak season for installers. If you book the job for late spring or summer, you can often negotiate a better rate. The installation is no different - you just cannot use it until winter.
Always use a HETAS registered installer
It might be tempting to save £200–£400 by using an unregistered fitter and applying for Building Control sign-off yourself. But a HETAS installer self-certifies the work, which means no inspection fees and no waiting. It also matters when you sell the house - buyers and solicitors want to see the HETAS certificate.
Choose a 5kW stove for most living rooms
A 5kW stove heats a typical living room perfectly well. People often go bigger, thinking more heat is better, but an oversized stove in a small room means you constantly run it on a low setting, which is inefficient and creates more soot. A correctly sized stove burns cleaner and costs less to buy.
What to Expect: The Wood Burning Stove Installation Process
From choosing your stove to lighting the first fire, here is how the process typically works.
- 1
Survey and quote
A HETAS installer visits to inspect the chimney (or assess where a twin-wall flue would go), check the room ventilation, and measure for the hearth. They should give you a written quote covering everything - stove, liner, hearth, labour, and sign-off.
- 2
Chimney swept and inspected
Before installation, the chimney is swept and inspected. The installer checks for cracks, blockages, and the general condition of the flue. If there are issues, they are flagged now rather than after the stove goes in.
- 3
Chimney liner installed
A flexible stainless steel liner is dropped down the chimney from the pot to the fireplace opening. The liner connects to the stove at the bottom and to a cowl or rain cap at the top. A register plate seals the chimney opening above the stove.
- 4
Stove fitted and connected
The stove is positioned on the hearth and connected to the chimney liner via a flue pipe. The installer checks all joints and seals, ensures the stove sits level, and tests the draw. Ventilation is confirmed - some rooms need an air vent to provide enough airflow.
- 5
Testing and sign-off
The installer lights a small test fire to check the draw and look for any smoke leakage. Once satisfied, they issue a HETAS certificate and register the installation. They should also explain how to operate the stove, control the air vents, and what wood to burn.
Frequently Asked Questions
How much does log burner installation cost?
Log burner installation cost is typically £1,500–£4,000 in total. This covers the stove itself (£500–£2,000), a stainless steel chimney liner (£400–£1,000), installation labour (£400–£800), and Building Regulations sign-off. Wood burning stove installation cost is similar. If you need a twin-wall flue system because there is no existing chimney, add £1,000–£2,500 on top.
Do I need a DEFRA approved stove?
If you live in a smoke control area - which covers most UK towns and cities - you must use a DEFRA-exempt stove. These stoves are designed to burn wood cleanly enough to meet smoke control regulations. DEFRA-exempt stoves cost slightly more but are now the standard choice for most installations. You can check whether your property is in a smoke control area on the DEFRA website.
Do I need a HETAS registered installer?
You do not legally have to use a HETAS registered installer, but if you do not, you must get Building Control approval separately, which costs £200–£400 and involves inspections. A HETAS installer can self-certify the work, saving you both the fee and the hassle. Using HETAS is strongly recommended for safety and resale value.
How much does a chimney liner cost?
A stainless steel chimney liner for a log burner costs £400–£1,000 supply and fit. The price depends on the length of the chimney and the grade of liner. A flexible 316 grade liner suits most wood burners, while a 904 grade liner is needed for multi-fuel stoves. Most installations need a liner - even if the chimney looks fine, an unlined flue is a fire and carbon monoxide risk.
Can I install a log burner without a chimney?
Yes, using a twin-wall flue system that runs up through the room and out through the roof or wall. This adds £1,000–£2,500 to the cost compared to using an existing chimney. The flue must extend to the correct height above the roof ridge and meet clearance distances from combustible materials. It is a bigger job but perfectly doable.
