The service
A new boiler, sized and fitted for your home
A boiler installation means removing your old boiler and fitting a new gas boiler that heats your radiators and supplies your hot water. Done right, it should give you years of dependable heating with lower running costs than an ageing, inefficient unit.
This service is for homeowners whose boiler is old, unreliable or expensive to repair, landlords replacing a boiler in a rental property, and anyone renovating, extending or moving to a different type of heating system. If your boiler keeps breaking down, parts are becoming hard to find, or your energy bills keep climbing, it is usually time to look at a replacement.
Gas boiler work must legally be carried out by a Gas Safe registered engineer. Ian is Gas Safe registered (no. 977988) and ACS qualified for boilers, with 25 years' experience in heating. We install Ideal and Baxi boilers, supplied and fitted from £1,995, with up to a 10-year warranty on new installations.
Most importantly, you deal with the same person throughout. Ian surveys your home, gives you an honest recommendation and a clear quote, fits the boiler, and tests the system before handing it over. As one customer put it after his combi boiler was fitted: the price quoted had no hidden costs and the whole system was fitted expertly.
If it's left
The real cost of an ageing boiler
An old boiler rarely fails all at once. It usually starts with small signs: the heating takes longer to warm up, the pressure keeps dropping, the boiler makes banging or gurgling noises, or the hot water runs lukewarm. Each repair costs money, and the next breakdown is often just around the corner.
Left too long, a tired boiler can stop completely in the middle of a cold Fife winter, leaving you without heating or hot water while you wait for parts. Older boilers also burn more gas to produce the same heat, so you pay more every month for a worse result. A boiler that is not burning correctly can also be a safety risk, which is why any warning signs should be checked by a Gas Safe engineer.
Common mistakes we see
- Choosing a boiler on price alone without checking it suits the home's hot water demand.
- Fitting a boiler that is too big or too small for the number of radiators and bathrooms.
- Skipping a system clean, so old sludge damages the brand-new boiler.
- Not registering the boiler or keeping up the annual service the warranty depends on.
- Using someone who is not Gas Safe registered to save money.

In detail
Choosing the right new boiler
No two homes in Fife use heating and hot water the same way. Here is what Ian considers before recommending a boiler.
Combi, system and regular boilers
A combi boiler heats water on demand straight from the mains, so there is no hot water cylinder or tank in the loft. Combis suit most flats and small to medium homes with one bathroom, and they free up cupboard space.
A system boiler works with a hot water cylinder, storing hot water so several taps and showers can run at once. It often suits larger homes with more than one bathroom. A regular (heat-only) boiler works with a cylinder and loft tanks, and can be the right choice where an older system is being kept.
Ian will explain the options that genuinely fit your home rather than pushing one type for every house.
Ideal and Baxi boilers
We install Ideal and Baxi boilers, two well-known brands with good parts availability in the UK. Warranty length depends on the model and on registering the boiler and keeping up its annual service, which is why we say up to a 10-year warranty on new installations.
Protecting your new boiler
Fitting a new boiler onto dirty pipework is one of the most common reasons new boilers struggle. Depending on the condition of your system, Ian will advise on what is needed so sludge and debris do not shorten the life of your new boiler.
Controls also matter. Correctly set thermostats and programmers mean you heat the home when you need it, not all day.
Homeowners and landlords
For homeowners, a new boiler is about comfort, lower bills and peace of mind. For landlords, it is about reliability and keeping tenants warm, with fewer emergency call-outs. We can also carry out the annual landlord gas safety check once the new boiler is in.
Moving or upgrading your boiler
A new installation is the best time to move a boiler out of a kitchen cupboard, into a loft or utility room, or to change from an old back boiler. Moving it means new gas, water and condensate pipework and a new flue route, so Ian will check it is practical and include it clearly in your quote before anything is agreed.
