Job Title: Lead Electrical Estimator / Senior Estimator – Solar & BESS
Salary: £45,000 - £50,000 basic + bonus
Location: Northamptonshire
Why this role
If you are an estimator with an electrical estimator background and you are ready for something bigger than simply pricing jobs, this could be the step that changes your career. This is a chance to join a growing commercial solar and battery business where your input will matter from day one. You will not be boxed into a narrow estimating role. Instead, you will work closely with leadership, contracts managers and delivery teams to help shape how projects are priced, tracked and improved.
For someone who is commercially aware, hands-on and hungry for progression, this is the kind of opportunity for an ambitious electrical estimator that rarely comes along at the right stage. The business wants someone who can support today's workload, learn fast, and grow into a broader commercial role as the company expands.
What you'll do
You will produce and support estimates across commercial solar PV and BESS projects, while also looking beyond the tender stage to understand how projects actually perform. That means reviewing completed jobs, analysing where margin has been won or lost, identifying cost leakages, and feeding those lessons back into future pricing.
You will work closely with contracts managers to track job costs against allowances, spot recurring variations or extra costs, and help strengthen estimating and commercial processes. This is a practical, commercially focused estimator role with real visibility across project delivery.
About the company
You will be joining a growing, ambitious business in the renewable energy sector, delivering commercial solar and battery storage projects as their lead electrical estimator. Still early in its growth journey, the company offers the energy, pace and visibility of a smaller organisation, where good ideas are noticed and strong people can progress quickly. It is a collaborative, office-led environment where people are expected to contribute, adapt and get stuck in.
About you
You may already be working as an Electrical Estimator or in a junior estimating management role within electrical contracting, electrical construction, solar EPC or M&E with an electrical bias. Solar experience would be highly attractive, but it is not essential if you have strong electrical estimating experience and the ability to learn quickly.
You will understand how projects are priced and costed, be comfortable reviewing quotes, allowances and commercial performance, and have the confidence to work with operational teams. Strong Excel skills, sharp attention to detail and a practical mindset will all be important.
Rewards & growth
Alongside a competitive salary and bonus potential, this Lead Electrical Estimator role offers genuine long-term progression. It is ideal for someone who wants to step up, take on more responsibility over time, and play a visible part in the growth of a successful commercial solar and BESS business.
How to apply
If you are looking for an estimator job in Wellingborough with progression, commercial solar exposure and the chance to influence performance across the business, this could be the right next move.
