If those prices don't include the electrician's costs of connection then to me they don't match up and I'd say your supplier/installer can't do maths lol. Pricing will change between supplier and of course electricians, and of course I'm working off the impression that the floors are flat where you want it installed. If the quote includes the electrical work, as in it covers everything besides tiling to where you can switch it on, then it looks reasonable to me and sits around the ballpark of what we paid. With the electrician's connection costs included then the figures match up better between the bathrooms and the living area, looking at it from a total per m2 viewpoint. If it includes the floor covering as well, then I'd say get on the phone and book the job straight away before they realise their mistake lmao. For instance if the quote is just for material and install, without electrical connection then the two bathrooms are quoted at $166.66 per m2 and the living area is quoted at $53.57 per m2. A large difference at cost per m2. If however the quotes include the electrical connection then you can average out the m2 cost across all three rooms and it amounts to $73.53 per m2. The electrician would be charging the same price for connection of each room (with only minor differences) if there is nothing out of the ordinary in any room. That means it's a static cost in each room that could make the bathroom quotes look inflated, and the living room look on the cheaper side. When you have a m2 quote on something across multiple rooms of different sizes, it's important to factor in anything outside of materials that's included in the quote. Assuming the install could be considered standard (whether it be underfloor heating, tiling, carpet, etc.) there will be other costs involved such as labour hours, wiring connection, installation materials, etc. Some can be considered static such as the electrician installing a single thermostat in each room, whatever actual size that room may be. Others will be more fluid such as labour hours for the tradesmen doing the install - will take a lot longer to lay tiles in a room of 56m2 than it will to lay them in a room 6m2. Whenever you are given a quote involving installations by m2, it's important to get them to detail what exactly is included in the quote. If you don't do this you run the chance of ripping yourself off. Let's say you get 3 different quotes from underfloor heating suppliers who all give you different prices but without details. One may look more expensive than the other two but actually be cheaper overall due to including everything up to 'turn on' phase, where the other two may only include supplying and laying the underfloor heating with you having to organise your own electrician after install.

You know, Alipetecampbell, I think a lot of good could be done by simply not allowing houses to be built unless they're designed by a qualified architect and signed off by a qualified engineer, and built to minimum standards that ensure proper passive climate control (insulation, glazing, orientation etc.) and social linkage issues - let's ban the food desert and the nappy valley. Developers have a vested interest in building cheap, and those rubbish houses sell because (a) there's not much else on the market and (b) superficially they look okay. You'd argue that what I'm proposing would raise housing costs, but let's stop making billionaires of developers, let's stop councils from charging silly money for planning fees (eminently doable if housing is professionally designed) and, as I have said above, use less land for more housing AND more greenspace too, and the cuts in cost these measures would create could go towards making all houses better.

The first thing we noticed was the beautiful light created by the back window and the blue curtains either side of it. What a fantastic room!

@Kate Thanks for commenting. I have wondered if I should report to the police, but my major fear is if the police get involved, and are able to prove he is damaging it, our insurance won't cover it, and he won't ever repair it. I know it says on the WA Government's website that we could send a letter saying he has a certain amount of time to come up with a solution, otherwise we could take him to court, but we don't particularly have the funds to sue our neighbour (who in my opinion is dangerous). And yes, I definitely won't be stooping to his disgraceful lows. To be quite honest, the worst I would do is record him on my phone and confront him. Thanks again Kate! :)
