In An Emergency

YOUR EMERGENCY ACTION PLAN

"Stay calm. Help is on the way. Follow these steps to protect your home right now."

01

Find your stopcock

Usually under the kitchen sink. Turn clockwise to stop all water flow into your home immediately.

02

Isolate the power

If water is near sockets or lights, switch off electricity at the fuse box — water and electricity are lethal.

03

Clear the area

Move valuables and furniture away from water to prevent permanent damage before we arrive.

04

Photo the problem

A quick photo helps us prepare the right tools and parts before we knock on your door.

Boiler & Heating FAQs

THE QUESTIONS WE GET ASKED MOST

The most searched boiler questions in the UK — answered by our Gas Safe engineers. Can't find your answer? Just call us.

Why does my boiler keep losing pressure?
Low boiler pressure is usually caused by a leak in the heating system — radiator valves, pipe connections, or internal boiler components. If your pressure gauge keeps dropping, call a Gas Safe engineer to locate and fix the source before it causes wider damage.
Why is my boiler leaking water?
Leaks can come from damaged seals, excessive pressure, corroded pipes, or faulty components like the pressure relief valve. Leaks should be inspected quickly — ignoring them leads to corrosion, water damage, and more costly repairs.
Why is my boiler making strange noises?
Banging, vibrating, whistling, or kettling sounds indicate trapped air, limescale build-up, low pressure, or a failing pump. Each sound points to a different fault — we diagnose it accurately on the first visit.
No heating but still have hot water — why?
This often points to a faulty thermostat, a stuck or failed motorised diverter valve, or circulation problems. It's a very common fault our engineers repair daily across London.
Why do my radiators stay cold?
Cold at the top usually means trapped air — bleed the radiator. Cold at the bottom means sludge build-up requiring a powerflush. Faulty TRV valves or system imbalance can also be the cause.
How often should a boiler be serviced?
Once a year by a Gas Safe registered engineer. Annual servicing maintains safety and efficiency, keeps your warranty valid, and catches small faults before they become expensive winter breakdowns.
How much does a boiler repair cost?
Costs vary by fault, parts, and boiler model. We carry out a full emergency diagnostic and provide a fixed £ quote before any work begins — you always know the price upfront. No surprises.
Do you cover CP12 Landlord Certificates?
Yes. We provide Gas Safety Certificates (CP12) for landlords across all our coverage areas — EN, N, NW, E, SG, AL and WD. Legally required annually for all rental properties with gas appliances. Call us to book.

⚠ WARNING SIGNS YOUR BOILER IS ABOUT TO FAIL

If you notice any of these, don't wait — call a Gas Safe engineer before it breaks down completely:

Boiler losing pressure regularly
Water leaking from the boiler
Strange banging or kettling sounds
Inconsistent or no heating
Pilot light keeps going out
Thermostat not responding
