Radiator Installation
From fitting a single new radiator in a recently added extension to replacing every radiator in a house with more efficient modern panels, Boiler Fit Direct Kent carries out professional radiator installation across Tonbridge, Royal Tunbridge Wells, Sevenoaks, and the surrounding mid-Kent area. Our Gas Safe registered engineers handle the full job — from assessing the correct radiator size for each room to the pipework connections, commissioning, and bleeding of the system.
Radiator installation costs depend on the type of radiator, complexity of the pipework connection, and number of radiators being fitted.
Why Choose Boiler Fit Direct Kent for Radiator Installation?
All pipework and gas connections are carried out by Gas Safe registered engineers — legally required for any work on a gas heating system.
We calculate the correct heat output for each room based on volume, insulation, window area, and external wall exposure. An undersized radiator cannot heat a room properly, no matter how high you turn the boiler.
Thermostatic radiator valves are fitted to every new radiator we install. Individual room temperature control reduces energy waste and heating bills significantly.
After installation we balance the whole system — adjusting lockshield valves across all radiators and bleeding trapped air — before testing and signing off.
No hidden costs. The price we quote is the price you pay, confirmed after we have assessed your property.
Fast response across mid-Kent. 50+ five-star reviews from local homeowners across Tonbridge, Royal Tunbridge Wells, and Sevenoaks.
When Do You Need a New or Replacement Radiator?
Room Additions and Extensions
A new room needs its own radiator. We assess the room size and insulation, specify the right output rating, connect to the nearest appropriate pipework feed, and commission the radiator as part of the existing system.
Old Radiators No Longer Heating Effectively
Older steel radiators corrode internally over time, reducing efficiency and output. If your radiator is more than 15–20 years old and feels noticeably cooler than it used to, replacement rather than flushing is often the better investment.
Upgrading to Double-Panel Radiators
Many older properties have single-panel radiators, which are less efficient than double-panel or double-panel double-convector (K2) models. Upgrading improves heat output without needing additional radiators.
Designer or Decorative Radiators
Renovating a bathroom, kitchen, or living space? We supply and fit a range of towel rails and flat-panel designer radiators that complement the room.
Improving System Balance
Sometimes a heating system is imbalanced because it was not designed with the right number of radiators. Adding radiators in consistently cold rooms can solve the problem permanently.
Our Process
Radiator Sizing
We calculate the correct output rating for your room based on volume, insulation, window area, and external wall exposure. Getting this right is essential — an undersized radiator cannot heat a room regardless of boiler output.
Pipework Planning
We plan the most practical pipework route from the existing feed to the new radiator position. This may involve lifting floorboards, boxing in pipes, or using surface-mounted covers — confirmed in the quote.
Installation & TRV Fitting
The radiator is installed with thermostatic radiator valves (TRVs) fitted as standard, allowing individual room temperature control.
System Balance & Test
We balance the whole system — adjusting lockshield valves on all radiators — and bleed the system to remove trapped air. We test fully before leaving.

What Our Customers Say
50+ five-star reviews from homeowners and landlords across Kent.
"Absolutely professional from start to finish. The engineer arrived on time, explained everything clearly, and left no mess behind. Our new Worcester Bosch is running perfectly. Would recommend without hesitation."
"Called about a boiler fault on a Wednesday and they were with me by Thursday. Diagnosed the problem in under an hour, fixed it the same day, and gave me a fixed price before touching anything. Exactly what you want."
"Booked a Gas Safety Certificate for my rental property — same week appointment, certificate emailed before the engineer left the driveway. Efficient and professional. Will use again next year."
"Used them for CP12 inspections across three properties now. Always on time, always professional, certificates issued same day. Exactly what a busy landlord needs."
"Had the whole central heating system replaced after moving into an older house. Brilliant job — finished on time, no mess, and the Nest thermostat they installed is brilliant. Very pleased."
"Power flush made a huge difference — radiators that were barely warm are now fully heating. Should have done it years ago. Fair price and good communication throughout."
Frequently Asked Questions
How much does it cost to fit a new radiator in Tonbridge?
A like-for-like radiator replacement typically costs £150–£300 including the new radiator. Fitting a new radiator in a room without an existing one (requiring a new pipework run) costs £200–£400. We confirm the exact price after a site visit.
Can you add a radiator to an existing central heating system?
Yes — provided the boiler has sufficient capacity to support the additional heat load. We assess the system at the time of the visit to confirm suitability before quoting.
Should I also get a power flush when replacing radiators?
If your existing radiators have been producing cold spots, or if your system has not been flushed in many years, a power flush at the same time as new radiator installation is worthwhile. Fitting new radiators into a contaminated system can reduce their lifespan prematurely.
How long does radiator installation take?
A single radiator replacement typically takes 1–3 hours. Fitting several new radiators across a property is usually completed in a single day.
What is a TRV and why does it matter?
A thermostatic radiator valve (TRV) automatically restricts hot water flow once the room reaches the temperature you have set. Rooms that warm up quickly stop drawing heat from the boiler automatically, reducing energy waste significantly and lowering your bills.
