Advice on buying a property with a faulty boiler

[Safd]

Hi all. I am in the middle of buying and selling. Our seller sent us the boilers paperwork and it states that the expansion vessel needs replacing, which was dated September 2022. We asked the seller to have the issue fixed as it is an ongoing problem since last year but there was no response from them. I just wanted to know if they can sell their property with a faulty boiler? I have done a general check online to see the cost of replacing it mentions that it could cost around £300, does that sound right to anyone? The lack of communication about it, is just adding to the stress, it's very frustrating.

Yes they can sell the property with a faulty boiler. The paperwork re the boiler is advisory for the new owners to be.
When I bought my house the boiler was old and needed replacing. Quite common when buying houses. Just a cost you need to factor in if you buy the house.

Hi yes u bought a house in 2019 that needed a new boiler

1500£ off the kitchen fund to get a new boiler but I was aware at purchase time

Of course they can sell their house in whatever state, I doubt they’ll fix it for you

£300 sounds about right, an expansion vessel is usually a fairly straightforward thing to replace. It might just need repressurising which is even easier.

(Of course the boiler could also be completely fucked, in which case it would cost more!)

The need to replace the expansion vessel might be related to the age of the boiler so more could go wrong. I had a quote recently to replace my 14 yo combi boiler and it was £6k+, double the cost of the original one!! Please check the cost of replacing the expansion vessel thoroughly as there's usually a call out charge on top of the repair cost itself, plus vat on the lot.

6k??????

Wtaf?

Not impossible.

Simple swap over with basic boiler could be as cheap as £1500. But sometimes things get more complicated, eg replacing old non-condensing boiler with a condensing one requires extra pipework, which can get complicated. And sometimes more recent rules require higher gas pressure at the boiler, which can require new gas pipe to be run all the way back to the meter - expensive and disruptive.

We have just had a new boiler fitted because of issues with the expansion vessel. Engineer said he could fix it but for around £300-450 but he wasn't confident it would last for long as he thought it linked to the age of the boiler. New boiler cost £3k fitted.

Tbh replacing an expansion vessel is very straight forward. Usually leave the original one in place as its inside the boiler - and fit a new vessel anywhere else in the house and plumb it onto the heating pipe - usually in hot press or even in the attic.
Unless it's compulsory to replace the original vessel but lots of plumbers just do the above.
New separate vessel is about 50 pounds or so and then plumber labour etc. 300 is a bit much.

My new boiler, in March this year, was £2000 including the labour.
