Complete Boiler Replacement Services
We replace ageing, inefficient and uneconomical boilers in homes across East Lothian. Before recommending a replacement, we inspect the current boiler, pipework, radiators, controls, flue route and hot water arrangement. We calculate the heat demand rather than choosing a boiler based only on the output of the old appliance. Oversized boilers can cycle frequently, while undersized models may struggle to heat the property or meet hot water demand.
A replacement becomes worth considering when breakdowns grow more frequent, parts become difficult to source or the boiler no longer meets the household's needs. We commonly find that customers also want better control over heating times and individual room temperatures. In rural East Lothian properties, we consider oil storage, external pipework and flue positioning as part of the replacement plan. We supply the agreed equipment and manage the work through one point of contact.
A replacement is often the moment to upgrade the wider system, so we also handle central heating installation and hot water cylinder work.

What Boiler Replacement Covers
-
Like-for-Like Boiler Swaps
We can replace an old boiler with a modern equivalent while retaining a suitable system layout. We still check output, pipe sizes, controls and flue compliance rather than assuming the previous specification remains right.
-
Old Boiler to Combi Conversion
A combi conversion can remove the need for separate stored hot water, depending on the property and water pressure. We assess simultaneous hot water demand before recommending this option for a household.
-
Back Boiler Replacement
We remove redundant back boiler equipment and plan a replacement boiler in a suitable position. This work can involve changes to pipe routes, controls, flue arrangements and the way hot water reaches taps.
-
Boiler Relocation During Replacement
Replacement creates an opportunity to move a badly positioned boiler. We assess pipe runs, condensate drainage, access for future work and the available flue route before agreeing the new location.
-
Rural Fuel and Heating Upgrades
Some East Lothian homes use oil or LPG because of their location. We review the existing fuel supply, external tank, pipework and heating demand when comparing a modern boiler replacement with an eligible heat pump option.
-
Controls and System Improvements
We can include new heating controls, thermostatic radiator valves and a magnetic system filter with the replacement. These additions help the new boiler regulate heat more effectively and protect it from debris circulating through older pipework.

Common Boiler Problems We Solve
-
Should I Repair or Replace My Boiler?
We assess the fault, boiler age, repair history, likely repair cost and availability of parts. An older boiler does not automatically need replacing, but replacement may make more sense when an expensive repair would leave other worn components unchanged.
-
How Much Will a New Boiler Cost?
We quote each replacement individually because boiler type, output, location, flue work, controls and system condition affect the cost. Converting to a combi or moving the appliance usually involves more work than a straightforward like-for-like swap. Our quotation sets out the agreed scope before work starts.
-
My Boiler Uses Too Much Energy
An older non-condensing boiler may send more usable heat out through the flue. We assess the whole system because bills also depend on controls, property heat loss, radiator performance and how the household uses heating. A correctly sized A-rated condensing boiler, carrying a strong ErP energy-efficiency rating, can reduce wasted energy, although savings vary between homes.
-
Parts Are No Longer Available
Manufacturers eventually stop supplying certain components for older boilers. We confirm whether the required part remains available and whether fitting it represents sensible value. If the boiler cannot receive an economical repair, we explain the suitable replacement choices without using the breakdown to push an unnecessary specification.

How We Handle Your Boiler Replacement
-
1. Assess the Existing Heating System
We inspect the boiler, controls, radiators, pipework, hot water setup and flue. We also discuss heating problems, planned property changes and the number of people using hot water. This gives us the information needed to plan the replacement.
-
2. Calculate and Specify
We consider the property's heat loss and hot water demand before selecting the boiler output. We then explain the available boiler types, control options and any useful system improvements. You receive a defined scope and a quotation based on the agreed work.
-
3. Plan the Changeover
Your point of contact arranges the work and coordinates the trades required for the job. We confirm access, equipment positions and practical details before starting. For rural East Lothian properties, this can include checking an oil tank, external supply pipe or alternative flue route.
-
4. Replace, Test and Explain
We remove the old boiler and dispose of it responsibly, fit the agreed replacement and complete the associated pipework, flue and controls. We test the system, commission the boiler and show you how to use the heating and hot water settings. We notify the replacement under Building Standards, hand over the compliance paperwork and explain the manufacturer's warranty requirements and future care.
Boiler Replacement Questions
-
We quote per job rather than publishing a figure that may not match your property. The boiler model, output, flue route, controls, location and required pipework all affect the price. We inspect the existing system in East Lothian and provide a quotation for the agreed scope.
-
We recommend assessing a 20-year-old boiler even if it still operates. Age alone does not decide the outcome, but efficiency, repair history, component condition and parts availability all matter. If it remains safe and economical to fix, we will explain that option before discussing replacement.
-
Many modern boilers work for around 10 to 15 years, although maintenance, system water condition, use and the original fitting all affect lifespan. We look at the actual condition of the appliance rather than treating a particular birthday as an automatic replacement date.
-
The timescale depends on the scope. A like-for-like swap usually requires less work than a combi conversion, relocation or back boiler replacement. We confirm the expected programme after surveying the property, then plan the changeover to limit the time without heating and hot water.
-
Yes, we assess replacement options for rural properties with oil or LPG heating. We check the boiler, external fuel storage, supply pipe, flue position and heating demand. We can also discuss whether a different heating technology suits the property, available space and household use.
-
Eligibility depends on the current funding route, household circumstances and property. Warmer Homes Scotland may support qualifying homeowners and private tenants, including households receiving certain benefits or meeting specific vulnerability criteria. We recommend checking eligibility with Home Energy Scotland before arranging any work.
-
Some qualifying households may receive fully or partly funded heating improvements, but there is no universal free boiler offer for every homeowner. Schemes and eligibility rules can change. Check the current position through Home Energy Scotland and obtain approval before committing to replacement work.
-
You can contact our East Lothian team from 7am to 7pm, seven days a week, on 01620 843000. We will discuss the current boiler, the problems you have noticed and the type of property before arranging the next step.
