I would like an experienced carpenter/painter to transform my small boiler room into a neater space, ideally I’d like the pipes boxed in with a door or opening to still access the pipes where necessary please. I have uploaded images to give a clear understanding of what I would like. The shelves & towel rail I have already purchased.

Hello! We need a small white cupboard with a door installed in the kitchen to cover the boiler. The aim is for it to blend in to the existing cabinet in terms of size and shape. Measurements: 920mm (H) x 400mm (W) Will also need a matching wall end panel x 2 and cupboard plinth x 1 500mm to complete the installation. Materials not included. Thank you :)

I’d like to book an annual boiler/heating service, and at the same time, get a quote to split my central heating into two independent zones. Currently, the Worcester boiler heats one flat. I would like: Zone 1 (First Floor): Underfloor heating controlled independently by its own thermostat/manifold. Zone 2 (Second Floor): Radiators controlled independently by a separate thermostat.

Looking for an experienced Gas Safe registered heating engineer/plumber to come to my flat in Kennington/Oval on Wednesday 30 September to look at two issues: 1. Baxi boiler / central heating system * Baxi Megaflo 24 System ErP, installed around 2016/17 when the flat was built. * The boiler/system is currently working, but the pressure gradually drops and needs topping up roughly once a week. * I’d like someone to diagnose why it is losing pressure and check for obvious issues such as the expansion vessel, pressure relief valve, filling loop or a leak elsewhere in the system. * The boiler is approaching 10 years old and hasn’t been serviced since I moved in during 2023, so I’d also like a proper boiler service/check while you’re here. * I’m particularly keen to make sure the system is reliable before winter and before I rent the flat out while travelling. 2. Leaking shower temperature control The thermostatic temperature dial on one of the showers is leaking around the control/faceplate area (photos attached). I’d like this investigated and, if it’s a straightforward cartridge/seal/washer issue, repaired at the same visit. Please only offer if you are Gas Safe registered and comfortable diagnosing both boiler/heating-system pressure issues and shower plumbing. I’m looking to spend around £150 for the visit/service and straightforward repairs. I have an Airtasker voucher worth £200, but this needs to cover the total including Airtasker fees, so please bear that in mind when making an offer. If replacement parts or more substantial work are required, I’m happy for you to diagnose the issue and quote me before doing anything additional. Timing is important: the voucher expires at the end of September, so I specifically need someone who can attend Wednesday 30 September. I can provide additional photos/details beforehand if helpful.

I’m looking for an experienced heating/HIU engineer to diagnose an issue with the heating controls in my flat. I have an HIU (Heat Interface Unit) and a wall-mounted heating controller/thermostat. The wall controller does not appear to be communicating with the HIU correctly — changing the heating settings/turning the heating on does not seem to trigger the HIU or radiators. The HIU has previously had a faulty actuator valve head replaced. The previous engineer replaced the actuator and got the heating working, but I don't think the wall controller/controls were properly investigated. I therefore need someone who understands BOTH: HIUs / Heat Interface Units Heating thermostats, programmers and control systems The communication/connection between the wall controller, receiver/relay and HIU Electrical/wiring diagnosis where appropriate I’m looking for someone to diagnose the actual fault rather than simply replace the actuator again. Please only apply if you have experience with HIUs AND heating controls/thermostats. I can provide photos of the HIU and wall controller, as well as the previous engineer's report.

We have a water heater Ariston that needs to be replaced as it’s not working in our restaurant . The water heater is working intermittently after resetting it which indicates it could be the heating element only

I have a boiler which has stopped working. I showed it to a plumber and he told me it needed a new Hot Water Actuator Valve but is quoting me ridiculous price for it when I know it is not that expensive. I need a plumber who can source this and fix my boiler.

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.
