Uneven heating, radiators that stay cold or controls that aren’t responding? Tell us the symptoms so we can assess the problem.
Thinking about underfloor heating?
Start with your room.
Then plan the system.
It’s worth discussing the heating before floors and finishes are decided. We’ll review your plans and explain what needs to be considered for the proposed installation.
- The rooms you want to heat and how you use them
- Your existing heating system and proposed changes
- Floor construction, available height and insulation
- Your intended flooring and control preferences
- Installation stages and coordination with other work
Look at the whole setup
Connected properly.
Explained clearly.
Heating work needs to make sense as part of your home’s existing system. We look beyond the individual radiator or room and explain how the proposed changes fit together.
You’ll know what work is included, how it will be scheduled and how to use any new controls once it’s complete. Explore our heating controls and energy efficiency upgrades for more ways to improve your existing system.

Before you decide
Your heating
questions answered.
A visit helps us give advice based on your home, rather than guesswork. Start with a request online.
Request a heating visitCan you replace or move a radiator?
We can assess the room and existing pipework, then discuss a suitable replacement or new position. We’ll explain the work involved and any making good that needs arranging.
Can underfloor heating be fitted in an existing home?
It may be possible, but the right approach depends on the property and planned work. We’ll review the floor construction, available height, heating setup and intended finish before recommending an option.
Can I keep radiators in other rooms?
Tell us which rooms you want to change and which you want to keep as they are. We’ll assess the proposed arrangement and explain the connections and controls needed for a suitable system.
Why are some rooms colder than others?
There can be several causes, so we’ll assess the system before suggesting work. Tell us which rooms are affected and whether the problem is new or has been happening for some time.
Will I need a new boiler?
Not necessarily. We’ll review your existing equipment and the changes you’re considering. If a boiler replacement needs discussing, we’ll explain why. See our boiler installation page for more information.
How much disruption will there be?
It depends on the scope. Replacing a radiator and installing underfloor heating involve different levels of work. We’ll discuss access, any floor lifting, the proposed schedule and expected interruptions before you agree to proceed.
Can I arrange a visit online?
Yes. Choose a preferred date and morning or afternoon arrival window, then add your address and job details. Your appointment is confirmed by email once approved. Installation dates are agreed separately after you accept a proposal.
