Boiler problems we can help with
Pressure, leaks and noises
Pressure that keeps dropping, drips from the boiler or pipework, and banging, kettling or whistling.
Parts and controls
Faulty fans, pumps, diverter valves, PCBs and thermostats, and frozen condensate pipes in winter.
Boiler repairs are not a DIY job. Only a Gas Safe registered engineer can work on a gas boiler. Before they start, ask to see their Gas Safe ID card and check the back to confirm they're qualified for your type of boiler. If you smell gas, leave the property, turn off the gas at the meter if it's safe to do so, and call the National Gas Emergency Service on 0800 111 999.
A few simple checks before you book can sometimes save a call-out. Look at the pressure gauge. Most sealed systems should read between 1 and 1.5 bar when the heating is cold. Check the boiler has power, that the thermostat and timer are calling for heat, and that the gas is on, for example by trying the hob. Note any error code on the display, as it helps the engineer bring the right part.
In a cold snap, one of the most common faults is a frozen condensate pipe. Modern condensing boilers drain acidic water through a plastic pipe, often to an outside drain, and if it freezes the boiler shuts down. You may be able to thaw an outside pipe with warm (not boiling) water, as your boiler's manual explains. An engineer can reroute or insulate it so it doesn't happen again.
Maidstone's hard water causes its own faults. South East Water, which supplies the town, says most of its water comes from underground chalk. Limescale builds up in the plate heat exchanger that heats the hot water on a combi, so hot water that swings between hot and cold, or a boiler that bangs or "kettles", often points to scale. On older systems, especially in homes that still have their original radiators and pipework, sludge in the water can block the heat exchanger and pump.
If your home has been flooded, don't use the boiler or any gas appliance that got wet until a Gas Safe registered engineer has checked it.
Once the engineer has found the fault, ask for a written price for the part and labour before they go ahead. Check whether the boiler is still under warranty, as the manufacturer may cover the repair. If the boiler is old and needs an expensive part, ask for a replacement quote to compare.
If you have no heating or hot water and there's a baby, an older person or someone unwell at home, say so when you post your job. Reviews on Trade Pilot come from real, invoiced jobs, so you can see how other homeowners rated an engineer's repairs.

Frequently Asked Questions
Most Gas Safe engineers charge £50 to £80 an hour, often with a call-out that covers the first hour and diagnosis. Common repairs, such as a new pump, diverter valve or fan, typically cost £200 to £450 including the part.
Usually a leak somewhere on the system, a faulty pressure relief valve or a failing expansion vessel. If you have to top up the pressure more than once every few months, ask an engineer to find the cause.
On a combi, it's often limescale in the hot water heat exchanger or a faulty diverter valve. Maidstone's hard water makes scale more likely, so ask the engineer about scale protection once it's fixed.
Often, if the repair is minor. If the boiler is over 10 to 15 years old and needs an expensive part such as a heat exchanger, compare the repair with the cost of a new boiler before you decide.
Only if they're on the Gas Safe Register and qualified for gas boilers. Ask to see their Gas Safe ID card and check the back before they start.
Turn the boiler off, catch the water and keep it away from electrics. If it's a steady leak, turn off the water at the stop tap. Then book a Gas Safe registered engineer.
