A proper role with room to grow

Smart Heat Experts Ltd is growing, and we're looking for the right person to join the team long term. The ideal engineer will already be confident with plumbing and heating work, hold the right gas qualifications, and care about doing a clean, safe and professional job.

You'll be working across boiler servicing, heating repairs, general plumbing, breakdowns, installations and everyday customer work. Over time, there will also be opportunities to develop further into air conditioning, heat pumps and renewables.

We care about qualifications, but we also care about attitude. We want someone who turns up properly, communicates well, respects customers' homes and wants to keep improving.

Pay matched to your experience, ability and ambition

We know not every good engineer is at the same stage.

Some engineers are already strong across servicing, repairs and fault-finding. Others have the right qualifications, a great attitude and want the chance to grow into higher-value work.

That is why we do not want to box the role into one flat salary. The package will be matched to your current ability, experience, customer care and long-term potential.

Why join us?

We are not looking for one fixed type of engineer. We are looking for the right person.

If you are qualified, reliable, good with customers and want to keep improving, there is room to grow here.

If you are already highly experienced in boiler breakdowns, fault-finding, controls or renewables, there is room for a stronger package and more responsibility.

How the working year fits together

Our work follows the seasons. Winter is our busiest and most structured time, when customers rely on us most, so you put in some extra weekday hours through the colder months.

Those extra winter hours are banked and given straight back to you in the summer. There is no standard weekend working, your weekends stay protected, and from July to October you get earned Friday finishes, giving you more of the summer to yourself.

It is a simple, fair trade. You work a little more when we are busiest, and take more time back when things are quieter, with predictable weekday hours and a genuine focus on work life balance.
