Doors at quieter sites in Berkhamsted and elsewhere in Hertfordshire can go many years between checks. A safety inspection looks at how the sensors, closing behaviour and emergency functions are working, and gives you a written record to keep on file.

What to think about for drive unit replacement in Berkhamsted
- If the door is on an escape route, the new drive unit must be set up to open, break out or be openable by hand, as the building's fire strategy requires.
- 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.
- Battery backup is easier to add with a new drive unit. It lets the door open or close safely in a power cut, which matters most on escape routes.
- Older shopfronts in Berkhamsted may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- Busy retail entrances in Berkhamsted may prefer the changeover after closing time or on a quiet trading day. Tell us your hours when you book the survey.

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.
How it works
- Send photos and the address. A few pictures of the door from both sides, the address in Berkhamsted and a note of who uses the entrance help us understand the job before anyone visits the site.
- No-cost survey on site. We arrange a survey at a time that suits the building. The engineer records measurements, fixings and power, plus any constraints such as listed status, opening hours or access for deliveries.
- Itemised quote to approve. We price every element of the work on drive unit replacement separately in a written quote that you can check, share and approve. Lead time and payment stages are stated, and nothing is ordered until you accept.
- Fit, test and hand over. On the agreed dates the engineer installs the equipment, commissions the operator and tests each safety function. You get a demonstration, the test record and any conformity paperwork that applies to the work.
If parts for your door in Berkhamsted are obsolete, talk to us before replacing the entrance. A free survey shows what can be kept and what it will cost.
Drive unit replacement in Berkhamsted: questions
Can the replacement in Berkhamsted include a service plan?
It can. After the changeover we recommend a service interval based on how heavily the door is used, and a service contract can be set up with a written record of each visit. Servicing is priced separately and agreed in writing before any visit takes place.
What will drive unit replacement in Berkhamsted cost?
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 Berkhamsted confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you replace automatic door drive units in Berkhamsted?
Yes. We are the contracting party for drive unit replacements in Berkhamsted, and the survey and changeover are carried out by specialist engineers we manage. The survey is free and checks that the frame and leaves are worth keeping. You then receive a fixed, itemised quote for the new operator, sensors and any other parts the door needs.
How long will our entrance in Berkhamsted be closed for the changeover?
A standard sliding door changeover typically takes a day, and a swing operator often less. The work can be scheduled early, after closing or at a weekend so it causes less disruption. Your quote shows the planned date and how long the entrance will be out of use.
How much disruption should we expect while the work is done in Berkhamsted?
Most installations take one visit or a short series of visits, with dust and noise kept to the area around the door. The engineer screens off the work area, keeps a route in or out where possible and clears up before leaving. Larger entrances, lobbies or structural changes take longer, and the quote explains how that work is phased.
What happens to the old door when a new one is fitted in Berkhamsted?
If the work replaces an existing door, frame or operator, removal and disposal are listed in the quote. The old door comes out only when the new one is ready to go in, so the opening is not left empty for longer than necessary. Making good to the surrounding wall, floor or ceiling is included where the quote says so.
Do businesses in Berkhamsted have to fit automatic doors?
No law says every building must have automatic doors. Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, and building regulations guidance in England calls for a powered door where an entrance door would otherwise be too heavy to open. An automatic door is often the simplest way to meet both.
