The Company
LAMTANS Engineering Ltd is a Manchester-based retrofit industry specialist, delivering home renovations, insulation, gas boiler installations, heating controls and renewable energy solutions to homeowners and commercial clients across Manchester and surrounding towns — including Stockport, Oldham, Droylsden, Ashton-under-Lyne and Tameside.
We also provide nationwide coverage for government grant schemes including ECO4 and the Warm Homes Plan.
A proven track record of improving homes, reducing energy bills and delivering high-quality workmanship — built project by project, from grant-funded insulation to full private renovations.
How We Got Here
We started on government grant schemes — helping eligible homeowners access fully or partly funded insulation, gas boiler and heating control upgrades under ECO4, subject to eligibility.
That work built deep expertise in energy efficiency, building construction and customer care. We saw first-hand how the right improvements transform a home — reducing draughts, cutting energy bills, and making properties warmer and healthier.
As our team grew, so did our range. We expanded into private home renovations and renewable energy installations, bringing the same high standards and customer focus to every project.
Today, LAMTANS Engineering Ltd is proud to be a fully industry accredited retrofit specialist offering a complete range of services under one roof — from full house renovations to solar panels and heat pumps.
What We Do
Our background includes extensive work on ECO4 schemes, where we have installed a wide range of energy efficiency and home improvement measures.
What Drives Us
Our mission is simple: deliver high-quality retrofit workmanship at fair prices, with complete transparency and consumer protection. What this means for you:
Every project — whether a full house renovation or a simple gas boiler upgrade — is treated with the same care and attention to detail.
The Difference
LAMTANS Engineering is a Manchester-based retrofit specialist focused on delivering high-performance energy-efficient solutions. Unlike general builders, we specialise in improving building fabric, reducing heat loss and installing low-carbon heating systems that deliver long-term value. We combine technical expertise with industry-recognised standards to ensure every project is completed safely, efficiently and in compliance with UK regulations.
We are not general builders. Our focus is entirely on retrofit solutions — energy efficiency upgrades, insulation improvements and low-carbon heating systems. Instead of working across unrelated construction services, we concentrate on targeted retrofit work that improves thermal performance, reduces carbon emissions and enhances long-term property efficiency.
