- The fault is a single, identifiable part

Replacement is usually better when

How long does boiler installation take?
Most straightforward replacements are completed in a day. Larger jobs, or installs that involve moving the boiler’s location, may take longer — we’ll confirm timing at the assessment stage.
How do I know if I need a new boiler?
Frequent breakdowns, rising repair costs, or a boiler over 10–12 years old are the usual signs. If you’re unsure, we’re happy to take a look and give you an honest answer either way.
Can you replace an existing boiler?
Yes — like-for-like replacements or upgrades to a different system type, depending on what suits your property.
Do you provide advice before installation?
Always. We assess your property and talk through the options before recommending anything, so you know exactly what you’re getting and why.
How much does a boiler replacement cost?
It depends on the boiler type, your property, and installation complexity. Call us for a straightforward quote based on your actual setup.
- What customers say
Trusted by Local Homeowners
“D&M assessed our roof properly before recommending anything, and were upfront that a full Solar PV system wasn’t worth it for our situation. That kind of honesty is rare”.
Jane H
“Our air source heat pump was designed around our actual insulation and layout, not a generic package. Installation was tidy and the handover explained everything clearly.”.
Robert M
“Our old solar thermal system had stopped heating water properly. Turned out to be a simple glycol issue — sorted in one visit at a fraction of what we expected to pay.”.
