The service

What a Boiler Installation Covers

A boiler installation covers every step needed to get a new boiler running in your home. We remove the old unit, fit the new one with its heating controls, prepare the pipework and radiators and test the complete system before we leave.

Choosing the right boiler is part of the service. Our engineers will assess your home and recommend the type, size, and position that best suit its layout and hot water usage, so you don’t have to figure anything out before contacting us.

This service is for you if your boiler has broken down, keeps needing repairs, is no longer efficient or will not cope with the demands of a planned extension.

Making the right decision

The Factors Behind Every Boiler We Recommend

 Our engineers assess your property and recommend the type, size and position that suit it, so the choice is clear before any work begins.

Boiler Type

Combi, system and regular boilers each suit a different style of home. We explain which one is right for yours and why.

Size and Output

A unit that is too small struggles and one that is too large wastes energy. We size it to your home and routine.

Hot Water Demand

How many bathrooms you have and how often they are in use together decide how much hot water you need on demand.

Position in the Home

Where the unit sits affects performance, noise and ease of servicing. We advise on the most practical placement.

Your Existing System

Pipework, radiators, and controls are checked first so that the new boiler works with your home, not against it.

Your Future Plans

An extension or extra bathroom changes what your heating must deliver. We allow for those plans from the outset.

Boiler types

Combi, System, or Regular: Picking the Right Boiler

Combi Boilers

Combi Boilers

A combi heats water straight from the mains whenever you open a tap, so it needs no cylinder and no loft tanks. It suits homes with one bathroom and decent water pressure. If two showers run at the same time, the flow to each drops.

System Boilers

System Boilers

A system boiler works with a hot water cylinder, so it can supply several bathrooms at once. Paired with an unvented cylinder, it gives mains-pressure hot water and suits larger households.

Regular Boilers

Regular Boilers

A regular boiler uses a cylinder and loft tanks, making a like-for-like swap the simplest option since existing pipework stays put. The right choice depends on your bathrooms and pipework, not just what looks good on paper.

Common questions

Boiler Installation FAQs

How long does a boiler installation take?

A like-for-like swap in the same position usually takes about a day. Converting from one boiler type to another, or moving the boiler, takes longer because of the extra pipework and flue work. Your installer should give you a realistic timescale after seeing the property.

In most cases, yes. Existing radiators normally work fine once the system has been cleaned. Radiators that are badly corroded, leaking, or too small for the room are worth replacing at the same time, because a new boiler cannot compensate for radiators that cannot release heat properly.

Usually, yes. Modern boilers waste less fuel than older models, so most households pay less to heat the same home. How much you save depends on the age of your current boiler, how you use your heating, and your controls.

Yes, but it adds work. Moving a boiler means new pipework and a new flue position, so it costs more than a like-for-like swap. It is often worth doing during a renovation, when floors and walls are already open.

A properly installed boiler that is serviced every year typically lasts around 15 years. Skipping annual services shortens its life and usually voids the manufacturer’s warranty, so yearly servicing protects both.

If your boiler is old or will struggle with the extra space, yes. Pipework and radiators are far easier to change while floors and walls are open, and it is the cheapest time to move a boiler or add radiators.
