CV-19 Update from Our Carrier DX

We hope you remain safe during these ongoing challenging times.
Following the Government’s announcement of a second lockdown across England starting at 12.01am on Thursday 5th November, we wanted to write and update you regarding our current service provision.
DX are identified by the Government as an essential business and we are committed to continue providing a service for our Customers’ during these difficult times in order to support our Country’s infrastructure and supply chain.
DX have plans in place to minimise service disruption during these extraordinary times and will endeavour to affect delivery within service criteria, however, there may be circumstances beyond our control which could lead to delays. The volatility of volumes in carrier networks, seasonal impact and increased online demand or reduction in availability of manpower due to COVID-19 cases and associated self-isolation issues are some of the situations beyond our control.
Our primary consideration remains to protect our customers, consignees and especially our DX colleagues whilst continuing to provide a functioning collection and delivery service.
DX continues to follow and monitor the official guidance from the UK Government, Public Health England and Local Authorities. We know it is vitally important for us to ensure that our robust procedures remain in place to support the health and wellbeing of everyone. On this basis, we continue to operate a contactless delivery procedure, as detailed below:
 If a proof of delivery is required, wherever possible, our driver will place the items on the recipient’s doorstep/Goods Inwards area, ring or knock the door as appropriate and then, where safe to do so, retreat 2 metres away.  Once the door is opened and/or the driver acknowledged, our driver will confirm and enter the recipient’s name and endorse with ‘CV’ (Coronavirus) in the signature field.  The ‘CV’ endorsed signature will then be classed as a successfully completed contactless delivery.  Recipients will still have the opportunity at point of delivery to highlight any damaged or missing item(s) and have this information noted against the proof of delivery (POD).  The POD will be classed as a clear signature (even when signed ‘CV’) unless endorsed otherwise.  Any claims arising will be processed in line with the relevant DX Conditions of Carriage.
We trust that you will understand and support the steps DX are continuing to take and we will notify you of updates as and when the need arises or as guidelines change. If you have any queries or require clarification, please do not hesitate to contact your local Depot team.
Finally, we once again thank you for your on-going support, patience and understanding, during these unprecedented times.
Kind regards,
Paul Ibbetson
Managing Director
DX Freight

Coronavirus Update

We are closely monitoring the current public health challenge linked to the Coronavirus (Covid-19) and we are applying the recommended health and hygiene practices to all aspects of our operations in the affected markets. Demand for our products remains high, we are managing our delivery commitments in order of receipt. Subject to public health advice and the health of our team members, partners and suppliers, we will continue production and supply, however the situation remains fluid and may change at short notice. We will update our status in our news section.




Coronavirus outbreak is spreading ever more day after day, causing significant worldwide business disruptions and restrictions within supply chains.

The TPFay team is monitoring the situation and working to maintain delivery continuity.

We are working with all our UK and International suppliers in order to assess potential negative impacts, taking into consideration their full supply chains.

Based on the public information disclosed by the national and international Health Authorities and taking into consideration the purchase orders already confirmed by TPFay Ltd, we currently have no major criticality to report.

We will keep monitoring the situation and we will put our best effort to avoid disruption to our supply chains in your interest, however TPFay Ltd shall not be deemed to be liable for any shortage due to Coronavirus outbreak, as it is a clear “force majeure” event out of our control.

We thank you in advance for your understanding and collaboration.

Kind Regards

Repair or New?

Here at TPFay we are looking to save our customers time and money.

Therefore we offer a repair service for old obsolete or burnt out heating elements. If you need to replace an old immersion heater or formed element, in many cases we can repair or rebuild your old heating element offering you considerable savings.

If you are looking for a repair or replacement please contact us for more information.

We always look to see if we can repair heaters, we do not like to waste materials or resources. Re-use is a valuable saving, in financial and environmental considerations, in some instances.

However, the construction of some existing heaters do not match our design and assembly criteria.

In these instances we use our judgement to determine, if repair of the existing heater is possible but may carry a great deal of risk of failure in service and during manufacture / repair process.

A contingency cost may be required to cover such risk.

The risk, combined with the time and resource required to attempt any repair, may be much greater than the material cost to manufacture a new heater, at this point we will offer the best alternative or replacement design.

Farewell to Brian

After over 27 years Brian Mitchinson has decided to retire from TPFay Ltd. Joining us when we only numbered 3 including the 2 directors. Brian has been an integral part of the DNA of this company.

We have made some tremendous changes in the intervening years, Most have been positive, and some were less so, but we all survived and continually learned and improved, though it all Brain was a steady and constant presence.

Brian would comment frequently on the “Time Machine” feeling of working here. It always seemed like five minutes since he started, but years had passed.

Now he has reached the time when he would like to stop. With the minimum of fuss and fanfare he has gone.

We wish him well and hope he enjoys his 7 day weekend.

Thank you Brian, we will miss you.

BSP Thread Sizes – A constant source of frustration for our customers

Brass Heads for Industrial Immersion Heaters

Industrial Immersion Heater Brass Screw Plug Head Components in various BSP Sizes from (¾”) 0.75″ to (2½”) 2.5″

It should be simple.

You measure something, and that is the size.


Not if you are measuring a thread, especially if it is a B.S.P. (Bristish Standard Pipe) thread……The size was originally based on the inner diameter measured in inches of a steel tube for which the thread was intended. This often causes confusion, as people think the size refers to the outside diameter of the male thread.

For example, the most common BSP Size for UK Immersion Heaters is 2¼” BSP.
However, if you measure roughly across the threads to check the diameter, it looks closer to 2½”, 2.58″ or 65.71mm, to be precise. But, how can you be precise when you have just struggled to remove an old immersion heater and you might be using a tape measure to try to gauge the thread?

If you ask for a 2½” BSP immersion heater to be made, it will arrive with a thread size of almost 2.96″ or 75.18mm, which will be really annoying as there is no way it will fit, it will be the thread size you asked for but not the size you need. It is the same for all other BSP threads so caution is required.

We at TPFay will try our best to guide you when you ask for a particular BSP size on a heater you would like us to make for you. We may seem to ask you to check the size you need, to the point of annoyance, but we are trying to guide you. We have encountered so many customers who have unwittingly ordered an immersion heater with the wrong size, it can be an expensive and frustrating experience.

Below is a table of common BSP sizes we use for TPFay Immersion Heaters and Element Fittings. Because we use it all the time it is simple for us, but we know it is less than straightforward if you are unfamiliar with the sizes, so was have a handy tip to help you identify the thread size you need if you are trying to measure around a male thread, it is almost impossible with a tape or desk rule.

  1. Cut a strip of paper that you can wrap around the thread you want to measure.
  2. Draw a Line across it with a pen or pencil.
  3. Wrap the paper strip once around the thread and make a second mark where the paper overlaps the first mark.
  4. Unwrap the paper and measure the distance between the marks. This should correspond to one of the measurements on C=Circumference (C)  mm  above.

If you have any difficulty, give us a call 03703 505058.

1978 to 2018 Forty Years of TPFay.

2018 is a big year for TPFay (Kirkby) Limited as we’ve reached the impressive milestone of 40 years in business. We were incorporated on 27 July 1978.

TPFay 40 years Trading 1978 to 2018

TPFay Certificate of Incorporation  -But, Companies House spelled our name incorrectly, Kirby not Kirkby, so we were re-named later in 1978.

Certificate of Incorporation

Over the last four decades we may have come a very long way from our humble beginnings.The business was founded by Terry Fay, manufacturing in his garage, accompanied by his father Peter.

Terry and Peter (TPFay) began by purchasing elements manufactured by others and custom forming and assembling them to bespoke designs and repairs of existing heater units. With stock stored in all corners of the house, including the loft, the whole family was always always closely involved with the business, day and night. The dining room was used as the office, even the kitchen oven was used to dry elements before sealing.

Our present 12,000 square foot facility couldn’t be more different! We now have purpose built production to manufacture our own heating elements from scratch.

A long and eventful journey, but we are still located next to the house where it all started.

In our 40 years of trading, we have always worked hard to ensure our products stay at the forefront of the market and put this success down to a combination of innovative design, technical and delivery services, developed with our customers in mind.

We continue to invest time and money to improve our products and services to make the best products for each customer and their particular requirement.

We’re incredibly proud to be a forward thinking, family run business with family values which remain true to this day.

We would like to thank; our customers and suppliers (past and present), from every part of the UK, and Worldwide, for continued support.

Our customers, for continually challenging us, making each day different, not allowing us to stand still.

Our suppliers who help us select the best products and services to enable us continually improve everything we do.

Last, but not least our team members, the entire TPFay family, past and especially present. You make us what we are.

We use all of the experiences gained over the past 40 years every day, and we use them to power forward for the next.

Here’s to another 40 years of success!

Farewell to Paul. Greetings to Alan.

It is with regret that we said goodbye to Paul Robertson in December. After 13 years he has decided to move on to another challenge with good company in the area, we wish him well.

With the start of 2018 we welcome Alan Daly to take up the role, of Packing operative, “Tzar of shipping Despatch and many things”. As with everything at TPFay, it will involve doing a bit of everything. We’re sure he will settle in quickly. Welcome to the team!
