Product design + engineering for non-standard industrial equipment
Independent decision support and focused engineering delivery for fabricated systems & buildable mechanical designs
Engineering effort gets wasted — not because the work is done badly, but because the wrong things get defined, prioritised, or carried through into design. Frugal helps clarify the right route, then deliver it.
Frugal is about the outcome: clear, robust, and cost-effective engineering solutions that avoid waste, reduce unnecessary complication, and make the most of what’s invested.
Operating as an independent mechanical engineering consultancy, Frugal provides product-definition and decision support alongside mechanical design and substantiation of non-standard industrial equipment and fabricated systems.
Specialising in tricky, non-template work where the route forward isn’t immediately obvious, Frugal helps clients clarify constraints, compare realistic options, simplify the route forward, and agree what 'done' looks like before committing to detailed design.
Frugal is best suited to SMEs and owner-managed manufacturers who value careful engineering judgement, simplification where it matters, and solid, manufacturable outputs — particularly where the real value lies in defining and engineering a solution, not simply adding CAD capacity.
What I help with
Practical support from problem-definition through to verified, release-ready design
Unstick the brief
When the problem isn’t clear or the team is stuck between options, I can help:
Clarify the real problem, constraints, and success criteria before time is lost taking the wrong route.
Define what ‘done’ looks like, expose the key trade-offs, and set a direction that can be taken forward into design with confidence.
Present the next steps, scope, and decision basis in a form that helps stakeholders understand, challenge, and get behind it.
Decision-ready options
Release-ready designs
Engineering problem triage
Structural confidence
Typical outputs include:
Definition / Options Reports
Annotated Design Concepts
Option Cost Comparisons
3D CAD Models
Technical Notes / Reports
Illustrated Assembly Sequences
Design Calculations
Finite Element Analysis
Structural Verification Reports
Engineering Drawing Packages
Bill of Materials
Design for Manufacture & Assembly
Supplier / Manufacturer Support
How we can work together
Most new projects begin at Phase 0 or as a Defined-scope sprint
Phase 0: Definition & Scoping
For when the problem is unclear or disputed
- Clarity on the real problem, the right route forward, and suggested next steps
- bullet 2
Defined-scope sprint
For when you know what you need delivered
- Pre-defined outputs delivered on an agreed basis, to an agreed standard
- bullet 2
Ongoing support retainer
For when you need ongoing decision support
- Responsive engineering advice and concise deliveries, as priorities evolve
- bullet 2
Engagements typically start from around £1,250. If you’re unsure where your project fits, email a short summary and I’ll let you know.
Client Feedback
Selected feedback from clients
5.0
“Tom is an excellent design engineer who brings clarity and direction. His deliverables are great value in their own right, and the wider benefits he brings — better decisions and fewer surprises — are the icing on the cake.”

“Many thanks for all your hard work — the detail is fantastic! We’ve had your design approved so we can now progress with fabrication. Thanks again for your incredible level of support and detail — we are all truly impressed with what you’ve done for us!”

Selected firms I’ve worked with directly include:
Over the years I’ve delivered practical engineering value through consultancy, contract roles and employed positions across a wide range of industrial organisations, including manufacturers, fabricators, engineering consultancies, contractors, and R&D teams in SMEs and startups.
Is this a good fit?
A quick way to see whether I’m the right kind of support
Likely a good fit
Engagements tend to work well when you…
- Want clarity — on next steps, trade-offs, and the right route forward, rather than allowing ambiguity or wishful thinking to persist
- Want a documented brief — the constraints and decision basis made explicit rather than left in people’s heads
- Can share context early — like CAD, drawings, photos, files etc.
- Allow enough runway to deliver it properly — not a same-day rescue
- Accept that design development may require iteration — and that additional refinement may need further time and budget
- Understand that iteration should be based on evidence — not just preference or inherited assumptions
- Accept responsibility for review and sign-off of the resulting outputs, or arrange an appropriate third-party check where needed
Probably a bad fit
It’s probably not a match if you…
- Need immediate turnaround — without allowing proper time and budget to define scope, share inputs, or do the work properly
- Want to push straight to detailing — before the real problem or route forward is clear
- Can’t share inputs or constraints — but still expect definitive answers
- Imply I’m not allowed to change anything — even when the real constraints might point elsewhere
- Are mainly looking for the cheapest CAD capacity — rather than judgement, outcomes and ROI
- Want close time-presence or day-to-day oversight rather than independent, deliverables-based support
- Need mainly styling or industrial design rather than real engineering
- Want me to take responsibility for compliance or fitness-for-purpose without an explicit checking/certification scope
If you’re unsure, email a short summary of what you need and I’ll tell you whether it sounds like a good fit
About
Frugal Philosophy
Frugal is about achieving a better overall engineering outcome: one that is simple where it should be, robust where it matters, and cost-effective without compromise. The aim is not to minimise spend at any cost, but to avoid waste, reduce unnecessary complexity, and make better use of the time, budget, and effort invested in design.
In practice, that means clearer problem definition, sounder engineering judgement, and fewer decisions based on untested assumptions. It means being wary of unnecessary complication, and working toward solutions with cleaner architectures, fewer parts, clearer interfaces, and less to go wrong in manufacture, installation and use.
Working basics:
- UK Limited Company – established 2012 (VAT registered)
- Independent – direct client work and specialist support to other consultancies on a freelance basis
- Nationwide – remote-first from my own office (not embedded on-site)
- Insured – PI/PL details available on request
- Confidentiality – as standard (happy to work under NDAs where needed)
- Outside IR35 – statement of work / deliverables-based only
- Lead times – not next-day; email context and I’ll confirm the earliest start
Product Definition & Engineering
Tom Hartley is a product-focused mechanical engineer: he works in the space between product definition and engineering delivery. He helps teams clarify what matters, compare realistic options, and agree a defensible direction — then translates that into a buildable output. His approach blends design judgement, engineering rigour and manufacturing realism, with a bias toward simple, robust solutions. The result is clearer decisions, fewer surprises, and a cleaner route to 'done'.

If you need to solve a problem and you’d like to explore whether I can help, drop me an email:
What to include
To help me give you a useful reply, please mention…
- What you’re building or dealing with (one or two sentences)
- What’s going wrong, what decision you’re trying to make, or where the brief still feels unclear
- Key constraints (budget, timescale, materials, interfaces, standards)
- What information you already have (CAD, drawings, photos, etc)
- Desired outcome (e.g. clearer brief, options report, CAD, calcs, FEA)
- Any deadlines and why they exist (so I can reality-check them)
