What to think about for drive unit replacement in Hertfordshire
- Ask for the paperwork. A converted door should come with its risk assessment, Declaration of Conformity and user instructions, which belong with your building and maintenance records.
- Check the power supply. A dedicated fused spur and isolator near the door is usually needed, and older installations sometimes need electrical work before the new operator goes in.
- Worn floor guides and rollers can shorten the life of a new operator. It is often worth replacing them during the same visit rather than coming back later.
- Heavy glass leaves need an operator rated for their weight. The survey records the size and glass type of each leaf so the right drive unit is specified.
- Doors linked to the fire alarm or access control in Hertfordshire need those links rewired to the new controller. Let us know which systems connect to the door.

Standards and rules in England
Standards are not retrospective, so an older door does not become unlawful when a standard is updated; a site-specific risk assessment shows whether any upgrades are sensible. BS EN 16005 is the current standard for the safety in use of powered pedestrian doors, and BS 7036-0:2014 is the British code of practice for risk assessment and risk reduction used alongside it. Standards are not law in themselves, but they are the recognised benchmark for showing an automatic door is safe to use, and we set up, test and document doors with reference to them.
Whoever motorises a manual door, or builds an automatic door from separate parts, may take on the manufacturer’s legal duties for the finished door: a risk assessment, a technical file kept available for the authorities, a Declaration of Conformity, the conformity marking and instructions. You receive the Declaration of Conformity and the instructions at handover. In Great Britain a new or converted powered door must meet the Supply of Machinery (Safety) Regulations 2008 before it is first used, and can carry the UKCA or the CE marking.
Workplace law (the Workplace (Health, Safety and Welfare) Regulations 1992) expects powered doors to have suitable and effective features to stop them trapping anyone and, where needed for safety, to open by hand unless they open automatically if the power fails. Doors at work must also be kept in efficient working order under a suitable system of maintenance.
How it works
- Get in touch. Call, email or use the form with the address and what you have in mind. If you are not sure which type of door suits, describe the entrance and we will suggest the options worth considering.
- Survey and advice. The survey costs nothing and carries no obligation. The engineer checks the site and explains which options suit the entrance, the people using it and the budget, before anything is priced.
- Quote in writing. You receive a fixed, itemised quote for drive unit replacement in Hertfordshire, covering equipment, installation, testing and handover, with the lead time and payment stages set out clearly.
- Install, test, explain. The engineer installs and commissions the door, tests the sensors, safety functions and emergency behaviour, and walks you through the controls. The handover pack records what was installed and tested.

Drive unit replacement in Hertfordshire: questions
Do you provide paperwork for the converted door in Hertfordshire?
Yes. When we fit a new drive unit we prepare the paperwork for the finished door, including the risk assessment, Declaration of Conformity and user instructions, and hand it over with the test results and settings. It belongs with your building records.
How are prices worked out for drive unit replacement in Hertfordshire?
Our guide is £1,995 to £3,995 excluding VAT (per door), the same guide prices we use across the UK. The free site survey in Hertfordshire confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Will you remove the old operator from our premises in Hertfordshire?
Yes. The old drive unit, sensors and any other replaced parts are taken away as part of the job, and the work area is left clean. Disposal is included in the fixed quote, so there is nothing extra to arrange or pay for afterwards.
What if the frame of our door in Hertfordshire is not worth keeping?
Then we will tell you. Damaged or corroded frames, glass that is not safety glass, or an opening that is too narrow for the people using it are all reasons to choose a new door instead. We can quote both options so you can compare them side by side.
Can automatic doors be fitted to a listed building in Hertfordshire?
Often, yes, but listed building consent is normally needed for changes that affect the character of the building, inside or out. Slim operators, concealed fixings and automating the existing door can all reduce the visual impact. Speak to the conservation officer at the local planning authority early; we can provide drawings and specifications to help.
Do I need permission from a landlord or the council before work in Hertfordshire?
It depends on the building. Tenants usually need the landlord's written consent before changing an entrance, and some changes to a shopfront or external door need planning permission. The survey notes anything that may need consent. We can supply drawings and product details to support an application, but the owner or tenant makes it.
Which building regulations apply to a new automatic entrance in Hertfordshire?
In England the guidance is Approved Document M (Volume 2) for access, Approved Document B for fire safety and escape routes, and Approved Document K for glazing and powered doors. A new entrance can count as building work, so building control should be involved before it is ordered.
