About us

Over fifty years of keeping buildings warm

Mellor & Mottram has been designing, installing and looking after heating systems since 1970. We are a family firm, and the same family still runs the business today.

Churches are where we made our name. Old stone buildings with high ceilings and listed fabric need a different approach from an office block, and we have spent a long time getting that right, from Heacham Parish Church to St Michael & All Angels in Macclesfield.

  • Grade I listed churches to modern chapels
  • Schools, hospitals, housing and industrial sites
  • Low carbon upgrades, including heat pumps
  • Temporary heat through our sister company, Boiler Hire UK
How we work

Planned properly, from survey to handover

Most heating problems on a job come from poor planning, not from the work itself. So we plan it properly.

01

Survey

We look at the existing plant, the building and how it is used, so the design starts from the facts.

02

Design & quote

A clear scope, a fixed price and a programme that works around services, term dates or opening hours.

03

Install

Our engineers carry out the work, with temporary heat from Boiler Hire UK if the building has to stay warm.

04

Look after

Servicing, maintenance and 24/7 call-outs for commercial clients keep the system running for years.
