What Do Heating Controls Include?
Heating controls refer to the little devices that tell your heating system how to behave.
EPC assessors inspect:
• Room thermostats
• Thermostatic radiator valves (TRVs)
• Programmers or timers
• Smart heating controls
• Zoned heating systems
Each piece helps prevent energy waste. Together, they become an EPC-enhancing orchestra.
Why Heating Controls Matter for EPC
A home that heats only what is needed performs far better than one blasting heat everywhere like an enthusiastic dragon. Good controls:
✅ Reduce unnecessary heating
✅ Help maintain stable indoor temperatures
✅ Cut energy costs
✅ Improve comfort
✅ Lower carbon emissions
EPC software rewards homes that can regulate heat efficiently, especially through room-by-room control and automation.
The Controls That Impress EPC Assessors Most
Heating controls are given different weightings depending on their intelligence and flexibility:
| Control Type | EPC Boost | Why It Helps |
|---|---|---|
| Programmers/Timers | Moderate | Schedules reduce waste |
| Room Thermostats | Good | Keeps temperature consistent |
| TRVs | Strong | Room-by-room precision |
| Smart Controls | Excellent | Automation + remote control |
| Zoned Heating Systems | Excellent | Heat only lived-in zones |
Adding TRVs alone can lift some homes one whole EPC band.
Heating Controls vs Boiler Upgrades
While a new boiler can be costly, heating controls might deliver similar EPC gains at a fraction of the price. Smart thermostats and TRVs often cost less than a weekend getaway, yet they reward you daily.
A small upgrade, a big EPC glow-up.
Ideal Heating Control Setup for EPC Success
The winning combo many EPC assessors love:
• A central programmable thermostat
• TRVs installed on all radiators (except the reference room)
• Heating zones where possible
• Optional smart integration for extra credit
Turning your heating into a responsive system is the secret to scoring high.
Mistakes That Hold EPC Ratings Back
Try to avoid:
⚠️ TRVs only in one room
⚠️ A thermostat placed in a poorly heated corner
⚠️ Manual-only systems with no scheduling
⚠️ Thermostats hidden behind curtains or furniture
Your heating controls need to sense your space clearly.
Quick Wins for Better EPC Scores
Upgrade ideas that deliver immediate impact:
• Install TRVs in every heated room
• Replace old dial thermostats with digital ones
• Add zoned systems in larger properties
• Go smart: smart thermostats track usage + adapt automatically
