Controls and zoning
For homes that need better day-to-day control over how different rooms heat and when.
Heating upgrades
Heating upgrades for homes that need more than a boiler swap.
If the system needs better control, better hot water, cylinder changes, or a wider rethink, this is the right place to start.

This page is for you if
The real problem sits beyond a straight boiler replacement.
Heating upgrades usually start when the house is not quite working as it should, even if the issue is hard to pin down at first.
- The hot water never feels quite right.
- The controls are not doing what you need them to.
- The cylinder or wider setup needs attention.
- A like-for-like boiler change would not solve the real issue.
How upgrade enquiries start
Photos of the setup usually make the first answer much more useful.
If you can send photos of the boiler, cylinder, controls, and anything awkward in the current setup, SJM Heating can usually advise more clearly from the start.
Upgrade routes
Common jobs this page covers.
These are the kinds of heating upgrades that sit between a simple swap and a bigger project.
Hot water and cylinder improvements
For homes where the hot water performance, cylinder setup, or overall balance needs more than a basic tweak.
Wider system changes
For jobs where a like-for-like boiler change would not solve the real problem with the heating setup.
What happens next
Some jobs stay as upgrades. Others turn into wider projects.
Once SJM Heating has seen the current setup, we can tell you whether it stays as an upgrade or moves into something broader such as underfloor heating, bathrooms, or a larger system rethink.
Why this route helps
It makes the problem easier to identify before anyone guesses at the solution.
That is especially useful for jobs where controls, hot water performance, and the wider system all affect the answer.
