Our speciality

The SSR upgrade — our permanent fix for F1 relay faults

Sticking relays are known to cause F1 relay faults on Acorn stairlift boards. We fit a solid-state relay in place of the original.

The SSR is an electronic version of a relay, but it avoids the arcing and sticking mechanical contacts that cause the fault in the first place. It's the same approach the manufacturer now uses on all new Acorn boards — and we fit it as standard.

  • No arcing, no sticking contacts — the mechanical failure point is designed out.
  • Fitted as standard on the Acorn 130, 180 and newer T700 boards we repair.
  • Now used by the manufacturer on all new Acorn boards.
  • Covered by our 6-month warranty, like every repair we carry out.

Our work

Real repairs from our workshop

A look at the boards, controllers and test equipment we work with every day — all photographed in our own workshop in South Wales.

Built in-house

Custom test gear we've designed and built ourselves

Off-the-shelf equipment doesn't always do what a mobility repair workshop needs. So we build our own — purpose-made rigs that let us test and diagnose faults far more quickly and accurately than we otherwise could.

Custom-built lithium battery discharge tester plotting a voltage curve

Lithium discharge tester

Discharges a pack under a controlled load and plots the voltage curve live on screen — so you can see a pack's real condition instead of guessing from a resting voltage.

Custom-built RF remote scanner displaying captured codes

RF remote scanner

Scans for and displays the codes being transmitted by RF handsets and remotes — an instant answer to whether a remote is actually sending anything.

Custom-built stairlift charger tester

Stairlift charger tester

Puts a stairlift charger under test and shows exactly what it's delivering, so a suspect charger can be ruled in or out in seconds.

M.R. Electronics charge test and battery meter

Charge test & battery meter

Our own inline meter showing charge voltage and current at a glance — the unit we reach for first on almost every battery or charger job.

Interested in a unit for your own workshop?

These were built to solve our own problems, but if one would be useful in your workshop we'd be glad to hear from you. Drop us an email and tell us what you're trying to test.

What customers say

Genuine reviews from Google

A few words from customers who've sent us their boards and controllers over the years.

I had occasion to have a Acorn Stairlift PCB tested/repaired. David gave me an excellent service by post, prompt and extremely economical. I would recommend this company to anyone considering its service offerings.

Len R.10 years ago · Google

David fixed a mobility scooter controller for myself, his turn around speed is very fast. I spoke to David on the phone over some problems I had which he was able to resolve. I am now back on the road thanks to David.
