What we do

Eight things we are called out for, and the page for each one tells you what usually turns out to be wrong before you ring.

Emergency boiler repairNo heat or no hot water tonight. We tell you on the phone whether somebody can reach you today, before you wait in.
Boiler repairThe rate agreed first, then the fault, the part and the labour written down before anything is touched.
Unvented cylinder repairNotifiable work needing G3 on top of Gas Safe. Our engineers hold both, so the boiler and the tank are one visit rather than two.
Boiler servicingThe visit where a scale reducer and a magnetic filter go in, which in London water is worth more than the service itself.
Power flushingFor cold spots at the bottom of radiators and a boiler that kettles. Worth more in a period conversion than in a new build.
Boiler replacementOnly when the arithmetic says so. We will tell you a boiler is worth keeping, which is not what everybody quoting you will say.
Landlord gas safety, CP12Certificate and any repair on the same visit where the appliance passes, so a let property is not off the market twice.
Electric boiler repairNo gas supply, which is a lot of London flats. Same engineers, same rate, same year on the parts.

Not sure which of those you need? That is what the call is for. Tell us what it is doing and we will name the job, and the rate, before anybody sets off. 0203 868 6134.

We know London property

Terraces, mansion blocks, conversions and new builds, and every system inside them.

Combi boilersThe wall-hung unit most London flats and smaller houses run on.
System boilers and vented cylindersA tank in the airing cupboard fed from the loft. Standard in period houses that were never converted.
Unvented cylindersMains-pressure hot water. Notifiable work needing G3 on top of Gas Safe, and our engineers hold both.
Electric boilersNo gas supply at all, which is a great many London flats.

Hot water gone but the radiators still warm? That is the call-out most firms get wrong, because it is usually the cylinder rather than the boiler. Most heating firms in London are combi only. Tell us what yours is doing and we will name the likely part on the phone, before anybody sets off. 0203 868 6134.

Safety

If you smell gas: do not touch any switches. Open the windows, leave the property, then call the National Gas Emergency Service on 0800 111 999. That line is free and open 24 hours. Call them before you call us.

If a carbon monoxide alarm is sounding: get everyone out immediately, then call 999 if anyone feels unwell. Do not go back in until the property has been ventilated and checked.

If the boiler locks out repeatedly: try one reset. If it locks out again straight away, stop. Repeated resets hide a fault that is still there, and on a gas appliance that is not a risk worth taking.

Book an engineer

Tell us where you are, what the boiler is doing, and whether there is a cylinder in an airing cupboard. With those three we can usually name the likely part, give you the rate, and book somebody in, all on the one call.
