Castlemilk Boiler Replacement

Boilers for Castlemilk, where the wind comes straight off the Cathkin Braes.

Ultimate Home Solutions supplies and fits new boilers across Castlemilk, beginning with a free survey and a clear quote you owe us nothing for. G45 sits high on the southern edge of the city, just below the Cathkin Braes, and the houses up here feel every bit of the weather that comes with that. Much of the stock is ex-council: four-in-a-block flats and terraces around Ardencraig, Barlia, Dougrie and Machrie, newer housing built through the regeneration, and older homes down towards Croftfoot and King's Park where a back boiler behind the fire is still not unheard of. A Gas Safe registered engineer looks at what you have before recommending anything, and a like-for-like combi swap is usually done inside a working day.

Boiler Ranges

Four heating systems. One Gas Safe team.

Housing in G45 covers a lot of ground. A two-bedroom four-in-a-block with one bathroom is well suited to a compact A-rated combi, which also frees the cupboard the old cylinder took up. A larger house at Croftfoot or out towards Carmunnock with two bathrooms in use at once can hold pressure better on a system boiler. Where a home is well insulated, a heat pump deserves a look too. These are the ranges we fit.

South side customers on the work, nothing tidied up.

“Bathroom installed within 2 weeks, which was fantastic.”

Ultimate Home Solutions were very quick in responding to my online enquiry. We had a visit arranged within 2 days. Sales person Kirsty was very knowledgeable and she guided us without being pushy or influenced our decision. Due to having no bathroom they put us down for express fit. Bathroom installed within 2 weeks which was fantastic. Every member of staff from the start to the installers were very friendly...

“From old to gold standard windows in no time.”

Having recently had our bathroom fitted by UHS, we were blown away by the quality and service so it was an easy decision to have UHS replace two of our windows. From the initial consultation through to booking the installation and the installation itself, it was a smooth process and everyone was super friendly and helpful. The fitters were efficient and were done in no time, taking time to clean up and make sure we...

Bathroom fitted by Ultimate Home Solutions

“Wow, wow, wow! First-class quality and value.”

Wow wow wow!! If you are looking for a first class bathroom that's amazing in quality and value then you must get it from Ultimate Home Solutions. Kirsty visited me and was outstanding in her attention to detail, clearly explaining the process and showing me the different designs and what would work best in my bathroom space. Micheal visited for a survey and was very polite. Brian, Dez and Paul arrived to start the...

Heating Engineers In G45

Why Castlemilk households ask us to sort the heating.

A proper look at the system before anyone talks about money, a boiler sized for the rooms you actually heat, and engineers who take the old unit away and leave the kitchen clean. That is what people from Barlia to Croftfoot ask for, and all workmanship is guaranteed.

FAQ

Boiler questions from Castlemilk and the streets round it.

What G45 households ask before ordering: cost, back boilers, flats, timescales, brands, cold rooms, smart controls, monthly payments and the guarantee.

Not what you were after?

Call us and a person who fits heating for a living answers, not a recording. Someone is on the phone every day and most calls are returned inside an hour.

Call 0800 029 3875
Do you fit boilers in Castlemilk?

Yes, right across G45 and the streets round about, Ardencraig, Barlia, Castleton, Dougrie, Glenacre and Machrie included, and on into Croftfoot, Simshill, King's Park and Carmunnock. The heating survey is free, there is no call-out fee, and the quote that follows carries no obligation.

What does a new boiler cost around here?

Most A-rated combi swaps land between £2,200 and £3,800 fitted, with the system flush, the gas certificate and the manufacturer registration in that figure. Replacing a whole system, boiler, cylinder and pipework together, is £4,500 to £7,500. A two-bedroom flat sits at the bottom of that range and a large house at the top. Various deposit options are available.

There is still a back boiler behind our fire. Can that go?

Yes. Back boilers sat behind the fire in a lot of houses on this side of the city, and they are slow, thirsty and getting hard to find parts for. The old unit comes out, a new A-rated combi goes in somewhere that makes sense, usually the kitchen or a cupboard upstairs, and the cylinder and the tanks in the loft can be cleared out with it. Reckon on 2 to 3 days rather than one.

Can you fit a boiler in a four-in-a-block flat?

We do it regularly. In most of these flats the boiler sits in a kitchen cupboard and a modern combi takes up less room than the unit it replaces. The engineer checks the flue route through the outside wall and where the condensate pipe can run, since those two things decide the position. If the building is factored or the walls are shared, mention it at the survey so the flue can be planned properly.

How long is the heating off for?

A day, for a like-for-like combi swap, with the heating and hot water back on before the engineer leaves. A conversion from an older cylinder system takes 2 to 3 days, a full system replacement 2 to 4. Allow around 3 to 5 weeks from the day you approve the quote for the boiler to arrive and your fitting date to come round.

Which make do you fit?

Worcester Bosch, Vaillant and Ideal, all A-rated. Greenstar carries Quietmark accreditation, which counts if the boiler hangs in a kitchen next to the living room. Vaillant ecoTEC is German-engineered and often goes into a full system job. Ideal Logic is the keenest value for a plain combi swap. The engineer picks for your house, and we register the manufacturer warranty for you.

The back bedroom never warms up. Will a new boiler fix it?

Sometimes, and sometimes the boiler is not the problem. A room that stays cold can be down to an undersized or sludged-up radiator, a system that has never been balanced, or heat going straight out through the wall. The engineer checks the radiators and the pipework as well as the boiler, and if the answer is a bigger radiator rather than a bigger boiler, that is what you will be told.

Do you do monthly payments on boilers?

Yes. We offer Buy Now Pay 12 Months Later, flexible credit up to 24 months, and longer-term flexible credit up to 10 years. The initial eligibility check is a soft search with no impact on your credit score, and gives an instant decision. Ultimate Home Solutions is authorised by the FCA as a credit broker (not a lender).

Can smart heating controls go in as well?

They can, on the same day. Hive, Nest, tado and Honeywell evohome are all fitted and set up before the engineer leaves. Being able to put the heating on from your phone on the way home is the part most people use, and zoning stops you paying to warm rooms nobody is in.

Where is your nearest showroom?

Inside Dobbies Garden Centre at Braehead, 75 Kings Inch Drive, Renfrew, G51 4FB, open 10am to 5pm every day, and our Kilmarnock showroom at Block 5, Unit 1, Glencairn Industrial Estate, KA1 4AZ opens Monday to Saturday, with Sunday by appointment. Call in and ask about a boiler by all means, though the survey itself has to happen at your house, because the engineer needs eyes on the boiler, the radiators and the flue.

What is covered if something goes wrong?

All workmanship is guaranteed, which is about how we fitted the boiler, the pipework, the flue and the controls. The boiler carries its own manufacturer warranty, registered by us on the day it goes in. If anything is not right, phone us and we will come back.
