How to Retrofit Underfloor Heating Without Raising Your Floor Level
“Will underfloor heating raise my floor height?” is a question we get asked often by renovators across Norfolk, and they’re right to be concerned. Even a minimal height increase as the result of retrofit underfloor heating in Norfolk can lead to time-consuming trimming of doors and adjusting skirting boards.
We’re always happy to be bearers of good news! The retrofitting system we use ensures that UFH installation doesn’t mean raising the floor level.
As long-established specialists in retrofitting UFH, Buxton Flow Screeds installs low-profile systems that cause negligible change in floor height. Our method combines ultra-slim pipes with a thin layer of levelling compound that hugs them tightly, ensuring powerful heat transfer without the bulky build-up. In this post, we’ll go through how we deliver radiant, energy efficient heating to Norfolk homes without compromising existing fixtures and fittings.
The Retrofitting Process – UFH That Respects Character
If you’re working in a period home in Norfolk, your original floorboards are part of its character. But they pose three important questions for your underfloor heating installer:
- Are they too uneven?
- Can the joists take the weight?
- Will I lose too much ceiling height?
Our UFH retrofit process is designed to answer each one of these.
Instead of removing the floorboards, our installers lay a lightweight, insulated panel system directly on top. This overcomes the weight issue and ensures the system is efficient. The panels have grooves that hold the thin heating pipes securely in place.
Then, to tackle uneven surfaces, we pour a thin layer of levelling compound over the top. This creates a flawless, level subfloor that’s also an excellent conductor of heat. Because this entire system is so slim, the total added height is only 15-20mm—your room’s original proportions are maintained, while radiant warmth is delivered fast and efficiently.

Your Retrofit Underfloor Heating Questions Answered
We know you’ll have questions. Here are answers to some of the things our Norfolk customers ask us about most often.
1. Can you install UFH on an upper floor?
This is where our lightweight, low-profile systems come into their own. Our systems only add minimal weight and are engineered to be safely installed on timber joists without needing any structural reinforcement. This makes them perfect for bedrooms and bathrooms upstairs.
2. Is a wet system better than electric for my renovation?
If you’re heating the whole room, we would always recommend a wet system. Electric mats can be cheaper to install, but their running costs are much higher. A wet system uses your boiler to heat water, which is more efficient and cheaper to run day-to-day.
3. How long does the installation take?
For a standard-sized room, the Buxton installers can usually lay the panels, pipework, and pour the levelling compound in 1-2 days. Levelling compounds dry rapidly and can be walked on in hours. They are usually fully cured after 24 hours, which is when the floor covering can be laid.
4. Is it possible to install UFH in just one room?
If you’re working on an extension, kitchen renovation, or bathroom, your UFH retrofit can be installed in that one room. Our systems can be connected to your existing central heating system and zoned with their own thermostat, so you get comfort and efficiency exactly where you need it.
