What radiator installation covers

A complete, end-to-end installation that focuses on performance, safety, and a neat finish.

  • Removal of existing radiators (where applicable) and isolation of the system
  • Supply and fitting of new radiator valves (TRVs or manual) and lockshield valves
  • Connection to existing pipework, with alterations where needed for correct alignment
  • Filling, bleeding and leak checks to confirm stable pressure and sound joints
  • Balancing the heating system to help radiators heat up evenly
  • Basic checks of system operation and heating controls after installation

When radiator installation is most useful

  • Your radiator is leaking, corroded, or no longer heats properly.
  • A room is consistently colder than the rest of the property.
  • You are renovating and want radiators repositioned to suit a new layout.
  • You want better temperature control with TRVs in key rooms.
  • You are upgrading the look and output of radiators to match the space.

How the work is carried out

First, the existing setup is assessed, including pipework positions, valve types, and radiator sizing for the room. The system is isolated and drained as required, the radiator is fitted and connected, then the system is refilled, vented, and tested. Final steps include checking for leaks, confirming heat-up performance, and balancing where needed.

After installation: performance and ongoing value

Once fitted, you should see more consistent heat and easier control of room temperatures. You will be advised on settings and simple checks, such as bleeding a radiator if air collects. If balancing highlights wider system issues, you will be told what they are and what options you have to improve efficiency.

Frequently Asked Questions

Can you help me choose the right size radiator for a room?
Yes, sizing can be based on room dimensions, insulation and how the room is used. The goal is to match heat output to the space so it warms up efficiently without over- or under-heating.
Do I need new radiator valves as well?
In most cases it is sensible to fit new valves when replacing a radiator, as old valves can leak or stick. TRVs can also improve comfort by giving better temperature control in each room.
Will the heating system need to be drained to install a radiator?
Often, yes, at least partially, so the pipework can be opened safely. The system is then refilled, bled and checked to make sure pressure and circulation are correct.
Can a radiator be moved to a different position?
Usually, yes, but it may require pipework alterations under floors or within walls. You will be advised on what is involved once the existing pipe routes and access are assessed.
Do you balance the system after fitting a radiator?
Balancing is recommended, especially if you are adding or changing multiple radiators. It helps distribute flow properly so rooms heat more evenly and the system runs more efficiently.
