What Is Included in Every Mo's Boiler Installation
No hidden extras. This is what you get for the fixed price we quote.
New boiler unit
We supply the boiler from an authorised distributor. All brands are genuine, properly warranted units.
Flue kit
The flue components to safely route combustion gases out of the property. Standard wall exit included.
Magnetic system filter
A magnetic filter fitted to the return pipe to catch sludge and protect the boiler. Extends boiler life and is a warranty requirement on most brands.
Chemical flush
A chemical system flush before installation to remove sludge and scale from existing pipework. Essential for warranty validity and boiler longevity.
Inhibitor treatment
Corrosion inhibitor added to the heating water to prevent future sludge buildup.
Full commissioning and testing
We set up and test the boiler properly before we leave. Not just fired up and switched on.
Gas Safety certificate
The Building Regulations notification and Gas Safe documentation required for the installation.
Warranty registration
We register the manufacturer warranty in your name so it is valid from day one.
If a power flush is needed on older or heavily sludged systems this is discussed and quoted separately before any work starts. We never add it to the bill after the fact.
What Does a New Boiler Cost in Glasgow in 2026?
Honest price ranges based on what we actually install in Glasgow properties. Every job is quoted individually before we start.
| Installation Type | Typical Price Range | Notes |
|---|---|---|
| Combi to combi swap | £1,800 to £2,500 | Most common Glasgow job, straightforward like-for-like replacement |
| System boiler with cylinder | £2,200 to £3,200 | Larger properties with higher hot water demand |
| System to combi conversion | £2,800 to £3,500 | Removes cylinder, changes pipework configuration |
| Back boiler replacement | £3,000 to £4,000 | Still common in older Glasgow properties, more complex removal |
All prices include VAT, labour, flue kit, magnetic filter, chemical flush, inhibitor and warranty registration. These are ranges based on standard installations. We give you a fixed price on your specific property before any work starts.
What Makes One Installation More Expensive Than Another
The main factors that affect your specific price. We explain all of these before we quote.
Boiler type
Combi boilers cost less to install than system or conventional boilers because they do not need a separate hot water cylinder. Most Glasgow flats and smaller homes suit a combi.
Boiler brand and model
Worcester Bosch and Vaillant cost more than Baxi or Ideal but come with longer manufacturer warranties. We explain the trade-off clearly and let you decide.
Flue position
A standard horizontal wall exit is included. Roof flues, extended horizontal runs or difficult access can add to the cost. We identify this during the quote visit.
Boiler relocation
Keeping the boiler in the same position is cheapest. Moving it to another room or another floor adds to the pipework and labour cost. We quote relocation separately and clearly.
Gas pipe sizing
Some older Glasgow properties have gas pipework that is undersized for a modern boiler. If we identify this during the quote visit we tell you immediately and include the upgrade in the price.
System condition
A heavily sludged heating system may need a power flush before installation. This is identified during the quote visit and priced separately. We do not discover it after the boiler is fitted.
Which Boiler Is Right for Your Glasgow Home?
The right boiler depends on your property type, your hot water demand and your budget. Here is how to think about it.
Combi Boiler
Best for: most Glasgow flats, smaller houses, properties with one bathroom. Heats water on demand, no separate cylinder, compact and efficient. Most common installation in Glasgow. Not ideal if you have multiple bathrooms running simultaneously or live in a larger property with high hot water demand.
System Boiler
Best for: larger Glasgow homes, properties with multiple bathrooms, properties that already have a hot water cylinder. Stores hot water in a cylinder so multiple outlets can run simultaneously. Larger upfront cost but better suited to higher demand.
Back Boiler Replacement
Still found in older Glasgow properties behind gas fires. These are no longer manufactured and must be replaced with a conventional or combi boiler when they fail. More complex removal and installation. We handle these regularly in older Glasgow tenements and terraces.
Not sure which suits your property? Call 07988 591331 and describe your home. We will tell you which type makes sense before you commit to anything.
Boiler Brands Mo's Team Installs in Glasgow
We are not tied to one manufacturer. We recommend the right brand for your property and budget.
Worcester Bosch
Up to 12 years warranty. Premium brand, widely regarded as the most reliable on the market. Higher upfront cost, lower lifetime cost.
Vaillant
Up to 10 years warranty. German engineering, excellent efficiency ratings, strong aftercare network.
Baxi
Up to 7 years warranty. Good value, reliable, widely available parts. A solid choice for standard Glasgow installations.
Ideal
Up to 7 years warranty. UK manufactured, good parts availability, competitive pricing.
Vokera
Up to 5 years warranty. Budget-friendly, good for straightforward installations where upfront cost is the priority.
Glow-Worm
Up to 5 years warranty. Sister brand to Vaillant, shares engineering but at a lower price point.
We recommend the brand that suits your property and budget, not the one with the best installer margin. Call 07988 591331 and we will talk you through the options.
Glasgow Home Considerations We Factor Into Every Installation
25 years fitting boilers in Glasgow has taught us what to look out for in this city's housing stock.
Tenement Flue Routes
Glasgow tenements were not designed for gas boilers. Flue routes in converted tenements can be complex. We survey the property before quoting to confirm the flue can be installed correctly. We will not fit a boiler where the flue cannot meet current safety standards.
Older Gas Pipework
Properties in older Glasgow postcodes sometimes have gas supply pipes that are too small for a modern boiler's demand. We check the gas pipe sizing as part of every installation quote and include any necessary upgrade in the price.
Back Boilers in Period Properties
Back boilers fitted behind gas fires are still common in older Glasgow tenements and pre-war terraces. Removing them requires taking out the gas fire and the surround as well as the boiler itself. We carry out these installations regularly and know what they involve.
How Mo's Boiler Installation Works
1
Quote Visit
Mo or one of the team comes out, looks at the property, checks the gas supply, identifies the right boiler size and type and gives you a fixed price. No call-centre quote, a qualified engineer who has seen the job quotes it.
2
You Choose Your Boiler
We present you with 2-3 boiler options across different brands and price points. You choose the one that suits your budget and needs. No pressure, no upselling.
3
Installation Day
We arrive with the new boiler, carry out the chemical flush, remove the old unit, fit and commission the new one. Most standard installations are completed in one day.
4
Handover and Documentation
We show you how to use the new boiler and its controls. We register the warranty in your name, give you the Gas Safety certificate and Building Regulations notification, and leave you with a contact number for any questions.
When Should You Replace Rather Than Repair Your Boiler?
The honest answer. We will tell you the same thing on site.
Repair Makes More Sense When
- The boiler is less than 10 years old
- The repair cost is less than a third of a new boiler
- The fault is a single component, not a systemic failure
- The boiler has been serviced regularly
- Good parts availability for your model
Replacement Makes More Sense When
- The boiler is over 12-15 years old
- You are paying for repairs repeatedly
- The boiler is inefficient and increasing your energy bills
- The heat exchanger has failed
- Parts for your model are becoming hard to source
- You have a back boiler that has failed
We will always tell you honestly which makes more financial sense. If your boiler is repairable and worth repairing, we will say so. If you are throwing money at a boiler that needs replacing, we will tell you that too. We would rather give you the right advice than charge for a repair that lasts another six months.

What Locals Say About Mo
250+ five-star reviews across Google, Trustpilot and Facebook, from real Glasgow customers.
“Our radiator pipe was bent and leaking. They answered straight away… Guy was here an hour later and he was wearing ID, very professional, patient and kind. We just got a new carpet in this room and he done an amazing job on getting little to no water on it. Couldn't recommend enough, price was reasonable.”

“We lost heating just in time for the coldest day of the year with a baby in the house… When I contacted them they were ready to dispatch that night. Fixed by the afternoon. Quoted that morning and no extra charges were added. Honestly cannot thank them enough.”

“As a small business owner, I needed a drainage company that could respond quickly. The team attended first thing in the morning, cleared the blocked drain and carried out a full CCTV survey. All documentation emailed across promptly. Professional, efficient and great value for money.”

Keep Your New Boiler Running With an Annual Service
Your manufacturer warranty requires an annual service by a Gas Safe registered engineer to stay valid. We can take care of that for you.
Why It Matters
Worcester Bosch, Vaillant, Baxi and Ideal all require annual servicing by a Gas Safe registered engineer to keep the manufacturer warranty valid. A missed service can void the warranty entirely. We offer annual servicing after every installation we carry out.
Book It With Mo's
One number for installation, servicing and any repairs. We keep a record of your installation date and can remind you when your annual service is due. Call 07988 591331 to discuss a servicing arrangement.
