Install Fastwarm underfloor heating
£250
Arkley, Greater London
11th Jan 2026
I have purchased a Fastwarm electric underwood heating kit (8 sq m) (https://www.fastwarm.com/fastwarm-electric-underwood-heating-mat-kit-10417-p.asp?v=0&variantid=14729) and insulation underlay (https://www.fastwarm.com/fastwarm-6mm-eps-insulation-pack-covers-10m2-20-boards-11151-p.asp) The heating mat needs to be hardwired to a fuse spur with a wall mounted digital thermostat. I am looking for an electrician with experience of installing this product. This is for the kids’ playroom in my house. I then plan on getting a separate person to fit laminate wooden flooring on top. There is currently a carpeted floor but i will remove the carpet in advance. There is a concrete subfloor, where the underlay will sit on top.
Repair bathroom radiators & install heating elements
£400
Pentonville, Greater London
11th Jan 2026
I had two new radiators installed in my bathroom last year, but they do not heat up. They are connected to the central underfloor heating system, but the water remains cold. A plumber attempted to identify the issue but couldn't, which suggests it's a structural installation fault in the pipes behind the wall rather than a quick fix. I am looking for someone to: 1) Inspect the pipes behind the wall to diagnose the connection fault and fix the issue so the radiators work with the underfloor heating. 2) Install electric heating elements (dual fuel) in the radiators as a backup. The existing radiators support dual fuel. I know from the previous radiators that there is existing wiring/power outlets behind the radiators, so no new cabling from the fuse box is required. These are the radiators that I have: https://www.traderadiators.com/catalog/product/view/id/367584/

Replace heating elements on a boiler
£200
Elephant And Castle, Greater London, SE1
27th Nov 2025
This boiler is not working as it should and I was recommended to replace the heating elements. So looking for someone to do this... It's not heating water well or fast enough, it costs me insane amount of money (like summertime around £100 goes to just have hot water in the morning for one shower session). Now it provides barely warm water after 3 hours of heating water. I don't know price for this work so please do let me know how much materials and labour will cost!
Highly recommend Egzon! He went above and beyond to fix our boiler, even cleaned the lime scale (which wasn't part of the deal), he did everything super quickly, came on time, and overall he's very nice person! Will definitely recommend him to our friends and will call him if anything.
