Question 1

Our Cumbernauld house has a flat roof, can a new boiler flue go through it?

Accepted Answer

Yes, and it is routine work when it is done properly. The flue needs a flashing kit that suits your roof covering, the right height above the roof and clearance from any parapet or nearby window. Where the roof is close to needing renewal, it is better to time the two together. We look at the roof as part of the free survey and the work round the flue is in the fixed price we give you. Call 07988 591331.

Question 2

How is this different from your boiler replacement page?

Accepted Answer

Replacement is where an existing boiler comes out and a new one goes in, which is the majority of jobs. Installation is the rest: a property getting a boiler where there wasn't one, a conversion or extension needing its own system, or a change of system type such as coming off a back boiler onto a combi. Same team either way, but the survey and the pipework are a bigger part of the job here.

Question 3

Do you do gas boiler installation specifically?

Accepted Answer

Yes, and it is most of what this page covers. A boiler installation in the UK means a gas boiler installation unless you say otherwise, so the survey, the fixed price and the Gas Safe commissioning described here all apply. If you are after an electric boiler, which is a genuinely different job with no flue and a much heavier electrical supply, that has its own page.

Question 4

How much does a boiler installation cost in Glasgow?

Accepted Answer

It depends on the boiler, the property and how much pipework has to change, so we survey before quoting rather than giving a number over the phone that moves later. What you get is a fixed price after the survey, and that figure is what ends up on the invoice.

Question 5

How long does the work take?

Accepted Answer

A straightforward install in a property already set up for it is usually a day. A system change, a first-time install or anything needing new pipework runs to two or three days. We tell you which before you commit, not on the morning we start.

Question 6

Will you size the boiler for my house or just match what was there?

Accepted Answer

Size it for the house. Matching whatever was fitted last time is how properties end up with a boiler too big for them, short-cycling and costing more to run than it needs to. We work the heat load out from the rooms, the radiators and the hot water demand, then recommend from that.

Question 7

Which boiler brands do you install?

Accepted Answer

Worcester Bosch, Vaillant, Baxi, Ideal and Vokèra mainly, and we are manufacturer certified across those. We will give you an honest opinion on which suits the property and the budget rather than pushing whichever carries the best margin that month.

Question 8

Do I need building control notified?

Accepted Answer

Yes, a new gas boiler is notifiable work in Scotland. We handle the notification as part of the job and you get the paperwork for your records, which matters when you come to sell.

Question 9

What warranty do I get on a first-time installation?

Accepted Answer

Up to 12 years on the boiler depending on the make, registered with the manufacturer on the day we commission it. Worth knowing that most manufacturers only honour the longer warranties where the system was flushed and a filter fitted at installation, which is why both are standard here rather than optional. Our own workmanship is guaranteed for 12 months alongside it.

Question 10

Can I get a boiler installed in a tenement flat with no existing one?

Accepted Answer

Usually yes, though it needs a proper look first. The two things that decide it are where a flue can safely terminate and whether the gas supply into the flat is adequate. Both are answerable on a survey visit, and we will tell you straight if a particular flat is not practical rather than starting and stopping.

Question 11

Should I be considering a heat pump instead?

Accepted Answer

Honest answer, sometimes, but not as often as the current push suggests. In a well-insulated property with room for the unit and bigger radiators, a heat pump can genuinely work. In a Glasgow tenement flat with solid walls, limited outside space and a shared close, the numbers usually do not stack up yet. We would rather say that than sell you something that disappoints, and we will tell you if we think your property is one of the ones where it does make sense.

Question 12

Do you flush the system as part of an installation?

Accepted Answer

Yes, and we fit a magnetic filter as standard. Putting a new boiler onto an old system full of sludge is the fastest way to void a warranty and shorten the life of the thing you have just paid for.

Question 13

Will you move the boiler to a different spot?

Accepted Answer

Often, yes, and a first-time install or system change is the natural moment to do it. Moving a boiler from a bedroom cupboard to a kitchen or utility means new gas, water and flue runs, so it adds to the cost, but it is much cheaper done now than as a separate job later.

Question 14

Do you use subcontractors for installations?

Accepted Answer

No. Mo and David do the gas and heating work themselves, same as every other job. On a spend this size it matters that the person who surveyed it is the person who fits it and the person you ring if something is not right afterwards.

Question 15

What happens on handover?

Accepted Answer

We set the controls up with you rather than handing over a manual and leaving. That means the timer, the thermostat and the hot water schedule set to how you actually live, plus the Benchmark logbook filled in and the warranty paperwork in your hand before we go.

Question 16

How far ahead do I need to book?

Accepted Answer

Outside winter, usually a week or two from survey to fitting. From about October the diary tightens because breakdowns take priority, so if you already know the boiler is on its way out, getting the survey done in late summer is worth doing even if you fit it later.

Question 17

How long will I be without heating and hot water?

Accepted Answer

Most of one working day on a straightforward install, longer where pipework is being rerouted. We tell you the realistic number at survey, and on a multi-day job we aim to leave you with hot water overnight wherever the system allows it.

Question 18

Do you take the old boiler away?

Accepted Answer

Yes, removal and disposal is part of the price, along with any old tank or cylinder that comes out on a system change. Nothing gets left in the close or the garden for you to sort out afterwards.

Question 19

Is there any reason to keep the tanks when we go to a combi?

Accepted Answer

Occasionally. If the mains flow at your house is weak, or several people run hot water at once, a combi may disappoint where stored water would not, so we test the mains at the survey before recommending one. Where the flow is good and the household is ordinary, the tank comes out and the cupboard is yours. Call 07988 591331.

Question 20

Who looks after the roof around the flue afterwards?

Accepted Answer

Our work, including the flashing round the flue, carries our 12-month guarantee on parts and labour like the rest of the installation. The roof covering itself stays yours to maintain, and if it is replaced in future, the roofer needs to dress the new covering round the flue rather than over it. Call 07988 591331.

Question 21

Can the boiler go in the cupboard where the old tanks were?

Accepted Answer

Often, and on a flat-roofed house it is one of the neater results. A cupboard on an inside wall can take a combi with a vertical flue above it, in space the tanks used to fill. What decides it is the clearance the boiler needs around it for servicing, and whether a flue can go straight up from there without crossing anything awkward. Call 07988 591331.

Question 22

Does a new boiler mean new radiators in a Cumbernauld terrace?

Accepted Answer

Not usually. The radiators are often fine once the system has been cleaned, which is done before any new boiler goes on. Where a top-floor room under a flat roof has always been cold, raise it at the survey, since flat roofs from that era lose heat faster than an insulated loft and a larger radiator in that room may be the real answer. Call 07988 591331.
