Certified scale calibrations for measurements you can trust
Achieve accuracy and compliance with UKAS or traceable calibrations.
Custom calibrated with 24/7 access to digital certification for complete weighing confidence.
Confidence in every weighing measurement
Scales are essential for consistent and reliable measurements, but daily use, environmental conditions, and gradual wear can cause drift that impacts experiments, quality control, and regulatory compliance. Regular scale calibrations ensure your measurements remain accurate, reliable, and audit ready.
As an ISO 9001 certified and ISO 17025 accredited lab, we calibrate all makes and models of lab scales to UKAS or traceable specifications. This gives your lab total flexibility to choose the calibration solution that best aligns with your fleet, processes, regulations and budget.Trusted and assured solutions
- Accredited UKAS calibrations for critical measurements
Performed to rigorous ISO 17025 standards, accredited UKAS calibrations deliver repeatable results that ensure compliance and safeguard critical lab processes. - Custom traceable calibrations for routine or non-critical scales
Traceable calibrations are performed according to your chosen specifications, providing fully documented, repeatable results that support quality assurance.

Flexible on-site or off-site options
Seamless in-lab calibration for uninterrupted workflows
Best suited for busy or regulated environments, or where scales can’t be moved, UKAS ISO 17025 and traceable calibrations options are performed directly in your lab, minimising downtime and disruption.
Flexible off-site service to fit around your schedules
Ideal for routine or non-critical scales, traceable off-site scale calibrations are performed in our environmentally controlled lab and scheduled around your workflows to fit around your operations.

FAQ
What types of scales do you calibrate?
All makes and models from bench, compact, counting to platform scales. Learn more about popular brands we calibrate including Mettler Toledo, OHAUS and Sartorius.
What’s the difference between UKAS and traceable scale calibrations?
UKAS calibrations are ISO 17025 accredited, providing the highest accuracy for critical measurements and regulatory compliance.
Traceable calibrations can be customised to your chosen specifications and are suited to routine or non-critical scales.
Both options include on-demand certification, adjustments plus detailed reporting to support audits and quality management systems.
Do you offer on-site and off-site calibration options?
Yes. We provide both UKAS and traceable calibrations on-site to minimise downtime for regulated or busy labs. For routine or non-critical scales, we also offer off-site traceable calibrations in our environmentally controlled lab, scheduled around your operational requirements.
Will I receive a calibration certificate?
Every calibration includes a complimentary, audit-ready certificate with 24/7 access via our secure online portal. This gives you instant documentation to support compliance, inspections, and internal audits whenever you need it.
How often should scales be calibrated?
Calibration frequency depends on usage, environmental conditions, and regulatory risk. Regular calibration prevents drift and helps ensure consistent results. For routine use, annual calibration is recommended, while high-precision or frequently used scales may require more regular three to six monthly checks. For expert guidance on the ideal schedule for quality system, start a conversation.
What if a scale fails its calibration?
If a scale is out of specification, we perform mechanical and electrical adjustments where possible. If it’s beyond repair, we’ll advise and guide you on the options and costs for suitable replacements to minimise downtime.
Can you manage multiple scales or recurring schedules?
Absolutely. We offer volume and preventative maintenance plans covering all scale makes and models to help keep your fleet accurate and compliant with minimal administrative effort. Our engineers also calibrate other lab equipment such as balances and pipettes so you can combine your needs to achieve further time and cost savings.

Testimonials
We've been working with C&M Scientific ltd (now Labserve) for the maintenance, repair and calibration of our lab equipment for some time, and we couldn't be more pleased with their service. Fran and team consistently deliver outstanding support - from prompt and clear communication to the friendly and professional attitude of service engineers. Whilst on site engineers are respectful of our working environment, carrying out their work efficiently and with minimal disruption to our lab activities. Their expertise is evident, and they always leave us with full confidence that our equipment is in safe hands, and service reports are always delivered promptly after visits, providing us with clear and comprehensive information. I would highly recommend them to any lab users looking for reliable, high-quality service and support.
"We have used Northern Balance (now known as Labserve) for a number of years for our calibration needs and without question, we have always found them to be prompt and professional, a great service."
"Northern Balance (now Labserve) has been servicing and supplying balances to us for more than 20 years. In that time we have come to always expect a high level of service given by friendly and knowledgeable staff."
"Gateshead Foodbank was awarded a grant from National Highways to improve our warehouse facilities. Top of our shopping list was a set of roll-on scales that would greatly improve our food handling and safety processes. Northern Balance (now Labserve) went above and beyond not only in that they ensured we had the most appropriate equipment to do what we wanted but that they made a magnanimous gesture in providing the equipment for free. That allowed us to use the funds freed to purchase other much needed equipment. The Trustees of Gateshead Foodbank would like to express their profound thanks to Paul and his team at Northern Balance (now known as Labserve) and would highly recommend them to anyone."

The support from service engineer, Danny and the wider Northern Balance team made the process seamless and straightforward. Thereby greatly complementing our in-house team in the build up to this key GMP milestone."
"Whilst your engineer was here I asked him to do a bit of training of our lab staff and manufacturing staff over the correct way to use a balance, clean a balance, correct maintenance etc. This was very useful to both areas of our company and I am appreciative of him doing it. It is precisely this kind of helpfulness that your engineers have shown over the years that has maintained our business with Northern Balance (now known as Labserve) and that keeps us with Northern Balance."

As well as helping to verify the suitability of the equipment for our production processes, your support also enabled us to resume the release of several important products on behalf of our pharmaceutical clients."
"It’s been a pleasure to be involved with your company, and I must comment that out of all the companies that we have deal with, without doubt, and by a street that Northern Balance (now known as Labserve) is the most professional and efficient. I’ve never had any reason to question the service you provide."
"When complete certificates are emailed to us electronically within hours of the calibration being completed, which is in my opinion testimony to the dedication and commitment of Northern Balance (now known as Labserve) to their customers. I would definitely use again and recommend the use of Northern Balance to others."
