In fact, most people don’t even notice their boilers until they break down, so you may be surprised to learn that a boiler replacement was found to be the most profitable home improvement.
A study by GoCompare revealed that contrary to popular belief, aesthetic improvements such as a new kitchen or home cinema could leave you at a financial loss, as the added value is much less than the average cost.
The average boiler replacement costs £1,995, yet it can increase your home’s value by up to £8,000, potentially giving you a hefty profit of up to £6,005, and topping the leaderboard of profitable home improvements.
Not only does a new boiler increase value, but it also offers reliability for you and any new owners/tenants to follow.

With most boiler companies offering warranties between 5 and 12 years (providing you have it serviced annually, read more about boiler services here), a new owner can rest easy knowing they won’t need to pay for any expensive repairs or boiler replacements anytime soon.
Another benefit is the cut to energy bills that can be expected with a new, more efficient boiler. According to the Energy Saving Trust, you could save up to £315 a year on energy bills when you replace an old boiler with a new A-rated efficient one.
Adding features such as a smart thermostat can also increase the profit you make, as this offers added convenience as well as greater efficiency.
Other profitable home improvements include off street parking, a charging point, energy saving measures and central heating.

This is because homeowners typically like to add their own style to their home to make it their own.
In regards to green home improvements, he added:
“Improving the green credentials of a house usually pays- a new boiler, insulation or energy saving measure along with security improvement will usually pay off but some additions like solar panels will be hard to get a payback on immediately.”
