How often should a central heating system be serviced?

We recommend having your boiler and heating system serviced every 12 months. Annual servicing keeps the system running efficiently, extends its lifespan, and is often a condition of the boiler manufacturer's warranty. It also means any developing problems are caught early, before they become expensive repairs.

Why are some of my radiators cold at the top but warm at the bottom?

This is usually caused by trapped air in the radiator, which can be resolved by bleeding it. If bleeding doesn't help, or if the radiator is cold all over, there may be a sludge build-up in the system or a faulty thermostatic radiator valve. Our engineers can diagnose and fix the issue quickly.

What is a power flush and do I need one?

A power flush is a deep-clean of your central heating system that removes sludge, rust and debris from the pipework and radiators. Signs that you may need one include cold spots on radiators, noisy pipework, a boiler that cuts out frequently, or discoloured water when you bleed a radiator. It significantly improves system efficiency and is often recommended before a new boiler is installed.

Can you add a radiator to an existing central heating system?

Yes. We can add new radiators to an existing system, replace old ones, or reposition them as part of a home renovation. We'll check that your boiler has sufficient output capacity before any additions are made and advise on the best approach for your home.

My heating is on but the house isn't getting warm — what could it be?

There are several possible causes: a boiler working below its rated output, significant sludge build-up in the system, poorly balanced radiators, or inadequate insulation. Our engineer will carry out a systematic check of your boiler, controls, and radiators to find the cause and recommend the most effective fix.

Central heating problems we fix in Battersea

If you need a plumber in Battersea for central heating faults, we handle everything from cold radiators to controls that are not doing their job. Our engineers work across SW11, Nine Elms and nearby areas, in mansion blocks, riverside flats and older terraces.

Cold Radiators

Cold radiators often come down to trapped air, sludge build-up, stuck valves or poor circulation around the system. We check each radiator properly, balance the heating, bleed where needed and look for the underlying cause so the problem does not keep coming back.

Power Flushing

If your system has cold spots, slow heat-up times or dirty water when you bleed a radiator, it may need a power flush. We use the right equipment to clear sludge and debris from the pipework and radiators, which helps restore even heat and better flow.

Radiator Replacement

A radiator can become inefficient through internal corrosion, leaking valves or poor sizing for the room. We replace tired or damaged radiators with the right model for the space, then test the system so it heats properly and looks tidy as well.

Smart Controls Setup

Smart thermostats and heating controls can save energy, but only if they are installed and set up correctly. We fit and commission controls so they communicate properly with your heating system, then show you how to use the features that matter day to day.

Noisy Heating Pipes

Banging, tapping or whistling pipes can point to air in the system, loose pipework, high pump pressure or expansion issues. We trace the noise source, secure pipe runs where needed and adjust the system so it runs more smoothly and quietly.

TRV Problems

Thermostatic radiator valves can stick, fail to sense room temperature properly or stop a radiator from heating as it should. We inspect the valve, the pin and the radiator balance, then repair or replace the TRV so each room can be controlled more accurately.

Expert Advice

“Banging pipes and slow-to-warm radiators are usually easy to put right. A proper flush gets Battersea heating running quietly and efficiently again.”
