I need my boiler serviced as part of the annual check

Airconditioner unit has stopped working buttons all working but flashing the wifi symbol tried connecting and reconnecting cleaning the filters its all empty and still its not blowing air

It’s a pitched roof with partial boarding, needs 300mm latest spec insulation. Access via hatch. 45m2.

My Duux North portable air conditioning unit is no longer cooling. I need a professional to inspect and repair it, as it may have a refrigerant leak. If possible, I would prefer to bring the unit to a workshop for inspection and repair.

I have the boiler installed but I need to install the thermostat to control the temperature. The boiler is a Greenstar 4000 and the thermostat is a Honeywell T3.

The thermostat of the towel heater has broken off and the thermostat is no longer working without it.

My home coffee machine, Rancilio Silvia Pro, is giving an E01 error (and occasionally an E05 error) and I would like it repaired by an accredited professional. Thank you!

I need a plumber to re-pressurize my boiler and to tighten the bathroom heater as it’s leaking at 8 AM on the 9th July 2026 please. I have guest staying in my flat and the only time they can do is 8 AM tomorrow morning.

You must be a plumber or a heating engineer. Boiler diagnosis completed as follows below and need someone to replace both parts. Parts to be ordered separately and not included in price here. - system pressure was low. I topped up the pressure and reset the boiler; however, the boiler still failed to fire. The appliance was displaying the fault code shown in the photographs provided. I referred to the manufacturer's instructions, which identify this fault as relating to the gas valve. I then contacted the manufacturer directly to confirm, and they advised that the fault is associated with the gas valve and ignition electrodes, with replacement of these components being the recommended course of action. The active fault codes displayed on the front of the boiler provide a clear indication of the fault condition being detected by the appliance, and the manufacturer has confirmed that these codes relate to the gas valve and ignition electrodes.

There’s a gap beneath my boiler that needs to be covered as it’s a possible entry point for mice. The pest control company has asked for a Perspex sheet to built and siliconed in place around the boilers paperwork. Would need to be custom fitted and make w a jigsaw. Thanks

Hi, I’m looking for a professional decorator or handyman to repair and repaint water-damaged walls in the common stairwell area of my apartment in NW3 London. There was previously a leak from my boiler (faulty ball valve), but this has now been fixed and the area is drying out properly. The walls currently have: • Brown water staining • Flaking / bubbling paint • Some minor plaster damage • Light mould in one lower corner I want the job done properly so the staining doesn’t come back through. The job likely requires: • Scraping back all loose paint • Treating any mould • Sealing with stain-blocking primer (e.g. Zinsser) • Filling / patch plaster repair where needed • Sanding smooth • Repainting (white/neutral to match existing) This is in a stairwell so access may require care (not very high ceilings but awkward angles). I’m not looking for a quick paint-over, I want it done properly so the issue doesn’t return. Location: NW3 London Flexible on timing but ideally within the next 1–2 weeks. Thanks!

Boiler pressure dropped - need someone to re pressureise

I have a boiler with 2 connecting pipes going into it. One of the pipes is leaking so just needs attention and tightening.

I would love a quote for a Boiler Timer replacement for my 1 bed flat. The boiler itself works fine, but it has to be turned on and off manually. The existing timer attached to the water heater switch is completely unresponsive - it does not display anything or respond to my attempts to reset. I have been operating the water heater manually since I moved in but would like to install a new digital timer so that I can program water heating automatically and easily. The boiler only affects hot water as my radiator system is electric. I would prefer this job to be completed in one visit so would like the replacement timer to be sourced by yourselves in advance or to be given guidance on which to order in advance so that it is ready to install on the same day as your visit.
