    Age and efficiency

    Boilers typically become less efficient after 10 to 15 years, and repair costs keep climbing. A modern A-rated replacement can be up to 30% more efficient than a 10-year-old model.

    Rising energy bills

    If your usage hasn't changed but your bills have, your existing boiler is likely losing efficiency. A new installation usually pays back in lower running costs.

    Frequent breakdowns

    Repeat call-outs, inconsistent hot water and uneven heating are all signs of a system that's struggling. Replacement is often the more cost-effective long-term option.

    Cost of repair vs replacement

    If a single repair quote is approaching or exceeding half the cost of a new boiler, replacement is almost always the better call.

    Frequently Asked Questions

    Same-day and next-day slots are often available for urgent boiler replacements across Midlothian. Many standard installations are completed within a single working day, restoring your heating and hot water with minimal disruption.
    Yes. We cover the full Midlothian area including Dalkeith, Bonnyrigg, Penicuik, Loanhead, Newtongrange, Mayfield, Gorebridge, Danderhall and surrounding villages.
    If your home has one bathroom and limited cupboard space, a combi boiler is usually the better fit. It heats water on demand without needing a separate cylinder. A system boiler works with a hot water cylinder and suits larger homes with greater simultaneous demand. Our engineers recommend the right type for your property during the free survey.
    No. Replacing or installing a gas boiler is classed as permitted development provided the flue meets positioning rules. If your property is in a conservation area or is listed, flue positioning may require additional approval; we'll flag this at the survey stage. Your Gas Safe engineer will confirm compliance during the pre-installation survey.
