Radiator Valve Fitting, done properly.
Radiator valves are the small, cheap components that quietly govern how much of your gas bill actually turns into warmth. Wrong valves in the wrong places is one of the most common reasons a heating system underperforms, and fitting the right ones properly is one of the fastest efficiency upgrades in any home.
Supply and fit of thermostatic radiator valves (TRVs), lockshield valves, angled, straight and corner valves. Includes drain-down, replacement, refill, purge and full system balancing after fitting.
Homeowners upgrading from ageing manual valves, anyone fitting new radiators, households wanting proper per-room temperature control, and landlords upgrading rental properties to hit energy efficiency standards.
Whenever existing valves leak, seize, or don't do the job. Also whenever you install a new radiator, refit a room after decoration, or upgrade to smart per-room controls.
Because TRVs let each room run to its own temperature, cutting gas use, and lockshields let the whole system be balanced so the boiler doesn't overcompensate for cold rooms far from the pump. Both are cheap, both make a real difference.
The cost of putting it off.
Old, wrong or missing valves quietly cost households significant money every winter.
No per-room control
Without TRVs, every radiator runs to the same temperature, you either overheat some rooms or underheat others.
Unbalanced system
Missing or wrong lockshields mean radiators closest to the boiler get hot fast; distant ones stay cool. The boiler runs longer to compensate.
Seized manual valves
Old manual valves seize open or shut. When they seize shut, that radiator's dead until the valve is replaced.
Weeping valves, damaged floors
Failing valve seals drip slowly onto floors, skirting and joists. The valve costs less than the flooring.
- Fitting TRVs to every radiator including the one nearest the boiler, one radiator on the circuit must remain a manual reference; usually a bathroom towel rail.
- Skipping the lockshield adjustment after fitting, leaving the system unbalanced.
- Replacing a leaking valve without draining down first, a very short-term fix.
A clear five-step system.
No guessing, no meter-running. Every job follows the same repeatable process, that's how the result stays consistent.
- 01
Room-by-room survey
Which radiators need what, TRV, lockshield, manual reference, and any angles/pipework quirks.
- 02
Drain-down
Controlled drain-down of the affected loop or the whole system, protecting floors and furniture.
- 03
Fit valves
New TRVs and lockshields fitted with fresh olives, PTFE-sealed and tested.
- 04
Refill and purge
System refilled, air purged, inhibitor topped up.
- 05
Balance and test
Lockshields balanced so every radiator hits temperature evenly. Combustion re-test where relevant. 12-month workmanship guarantee.
What you actually get.
Room-by-room temperature control
Set bedrooms cooler, living rooms warmer, without changing boiler settings.
Gas savings from balancing
A properly balanced system runs the boiler less to hit the same overall warmth.
No more sticking valves
New TRVs open and close smoothly for years, not stick shut mid-January.
Leak-free joints
Fresh olives and proper compression fittings, not the recycled ones a previous engineer left in place.
Ready for smart controls
TRVs are a prerequisite for wireless zone control from smart systems like Tado and Evohome.
12-month workmanship guarantee
Every valve fitted is covered for a year against workmanship.
The detail that matters.
There is a right valve for every position on a radiator and every configuration of pipework. Getting this right first time saves rework and leaks.
TRVs
Thermostatic radiator valves let each radiator run to its own set temperature. Every room except one (usually where the reference room stat lives) should have a TRV. Modern TRVs are quieter, smaller and more reliable than older versions.
Lockshields
The 'other' valve on the radiator, used to balance flow. Adjusted once at commissioning and then left alone. Every radiator needs one; a system with unadjusted lockshields cannot be efficient.
Angled, straight and corner valves
Chosen to match how pipework enters the radiator. Pipes coming up from the floor use angled valves; pipes coming out of the wall use straight; awkward pipework uses corner valves. Wrong-angle valves look ugly and often leak.
Smart TRVs
Wireless TRVs (Tado, Evohome, Hive Radiator Valves) let each room follow its own schedule from the app. Only worth fitting if the base heating controls and lockshields are set up correctly, otherwise the savings evaporate.
