Radiator TRV adjusted so it controls room temperature properly. Stuck valves freed, loose heads secured, settings checked and explained.
When Your Radiator Won't Obey
You turn the TRV down but the radiator stays red hot. Or you turn it up and nothing happens. Or the head just spins loosely and clearly isn't doing anything.
Most TRV problems are fixable without replacing the valve.
💡 Pro tip: TRVs that haven't been adjusted in years often seize. The valve pin gets stuck. Takes minutes to free it, saves you from overheating rooms.

| Head won't turn (seized) | Head cracked or broken |
| Head turns but nothing happens | Valve body leaking |
| Radiator always hot | Pin completely seized (rare) |

What It Costs
Our minimum callout: £60 (covers first hour).
Adjusting one TRV takes 10-15 minutes, so you'll pay £60. If you've got multiple problem TRVs around the house, we can do them all in one visit - much more efficient.
💡 Multiple radiators? If several TRVs need attention, mention it when booking. We can service them all together.
Perfect For You If...
✅ Stuck TRV - won't turn or seized solid

What to Expect
Step 1: Check The TRV
See what's actually wrong - stuck head, seized pin, loose fitting, or broken mechanism.
Step 2: Remove & Service
Take the TRV head off (doesn't affect the radiator), check the pin underneath, free it if stuck, clean any debris, maybe lubricate.
Step 3: Refit & Test
Put the head back on properly, turn it through all the settings, check the radiator responds as it should.
🔧 DIY Tips
You can service your own TRV if you're careful:
🔧 What you'll need
- Adjustable spanner or grips
- WD-40 or GT85
- Cloth for any drips
- Nothing else
🔨 For a stuck TRV head
- Try turning it while pulling outwards (sometimes just stiff)
- If totally seized, look for a retaining ring or screw
- Remove ring/screw and pull head straight off
- Underneath you'll see a brass pin
- Spray WD-40, work the pin up and down with pliers
- Refit head, test
📊 Understanding TRV settings
- 0 or * = Off (radiator cold)
- 1 = About 10-12°C (frost protection)
- 2 = About 14-16°C (bedroom temp)
- 3 = About 18-20°C (living room temp)
- 4 = About 21-23°C (bathroom temp)
- 5 = Max (usually 25°C+)
⚠️ Common DIY mistakes
- Forcing a stuck head (you'll break it)
- Removing the whole valve (water everywhere - you just want the head)
- Over-lubricating the pin (it gets gunky)
- Not putting the head back on properly (it won't grip)
💡 Pro trick: Once a year (usually September before heating season starts), turn all your TRV heads from 0 to 5 and back a few times. Stops them seizing from being left in one position all summer.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
🎨 While I'm there: TRV adjustment is quick. If you've got other heating issues - radiators not heating evenly, noisy pipes, bleeding needed - mention them. Can often sort multiple things in one visit.
TRV vs lockshield: Each radiator has two valves. TRV is the one with numbers that controls temperature. Lockshield (other end) controls flow rate and shouldn't need adjusting unless you're balancing the system.
Smart TRVs: Modern smart TRV heads (programmable, WiFi-connected) fit on standard TRV bodies. If your mechanical TRV works but you want smart control, the body might be fine - just upgrade the head.
Frequently Asked Questions
What is a TRV and why would it need adjusting?
TRV stands for Thermostatic Radiator Valve - the twisty knob on your radiator with numbers 1-5. It controls how hot that specific radiator gets. They need adjusting if they're stuck, loose, or not responding to the settings. Sometimes they just need the head pulling off and refitting properly.
My TRV is stuck and won't turn - can you fix that?
Usually yes. Often the valve head has seized to the valve body (especially if it's been left on one setting for ages). Removing the head, freeing the pin underneath, and cleaning/lubricating it sorts most stuck TRVs. If the valve itself is seized solid, that's a replacement job.
The radiator is always hot even when I turn the TRV down - why?
The valve pin underneath is stuck open. When you twist the TRV head, it should push a pin down to restrict flow - but if that pin is stuck up, water flows regardless. I can remove the head and free the pin. Quick fix.
Can you replace a broken TRV head?
Yes - TRV heads are replaceable without draining the system. If yours is cracked, the numbers worn off, or it's just not working, I can fit a new head. Most modern TRV bodies are standard fit.
Will adjusting my TRVs save money on heating?
Potentially yes. If your radiators are currently all blasting full heat because the TRVs are stuck open, you're wasting energy. Properly working TRVs mean you only heat rooms to the temperature you actually want.
