Why do boilers in rented properties deteriorate faster than those in my own home?

Short cuts during servicing can cause issues, I hear that this is more likely to happen if you use nationwide services rather than a trusted local – they have a reputation to lose and word of mouth support is important for them.

It was reported that council tenants who had ASHPs fitted, dread servicing as too many times problems get created.

Simple answer. Because the boiler is always the LL’s problem that’s why. No need to look after it, if it breaks down LL problem…

If tenants paid £2.5 – £4k for one, then I would imagine they would be looked after for a lot longer.

Many landlords skimp on buying a quality boiler.

Part of the problem is condensing Combi boilers. Tenants often have no idea how to check the pressure or what to do if the pressure has dropped a little – not always a sign of a leak, and certainly very few know what to do if they fill the system too high.

Also most tenants don’t give a damn as not their problem, not their money, and will be gone with the wind and no responsibility

They turn it off and on thinking they save money they also press all the nobs
And they don’t care if it shuts down

You are right!
It’s because some engineers know it’s a rental property and therefore know the landlord will pay for repairs, as they know a second quote is unlikely.
My letting agent sent an engineer to look at an issue in my rental property. Engineer found several issues, including a hole in flu that needed to be replaced urgently.
Unbeknown to letting agent and engineer i had a maintenance contract with British Gas.
I arranged an urgent BG appointment who said they could not find any of the issues identified by previous engineer. A supervisor from BG confirmed the same.

I am a landlord who used to install central heating himself before it regulated. I once watched a gas safe regulated gasman service my partner’s boiler. He broke the seal to the flue on the top of the boiler and then put it together again and put back the cover. I once had a very good gasman who was the manufacturer’s recommended engineer. I asked him whether he serviced his own boiler every year and he said ” Of course not. It’s a very pure fuel and doesn’t produce soot so it only needs a service when a fault happens “.

Many Renters don’t even care about their own maintenance nevermind the property they rent (boiler included). In addition they occasionally feel resentment for paying rent and furthermore others who come to service the property are more likely to use the opportunity ( comes around every year by law) of taking advantage as the owner is not around

Always get a decent one. Not a ferolli or something rubbish.
My 2 have a ideal logic 24+ with a 10yr warenty. Put in 2017 not a single issue.
Other one had a main ecotec 30 (basically a baxi) in 2021 and again no issues
Years back I had to rent a house for a few months and the landlord had a ferolli in. Over 4 month we had 9 calls outs and even the plumber said and I quote (I told him not to get this 💩 in) 🤣🤣🤣

If you need to replace then ensure the model has a stainless heat exchanger and not an ally one

I only ever use reputable local heating engineers and the only problem I have ever experienced was with Hometree.

However, I am also aware that there is a high percentage of tenants who don’t know how to operate the programmer, rarely bother to read the manual, happy to continue pressing the reset button until the boiler finally gives up and they then report the problem, or just switch it on and off at the mains
