Covering St Albans and nearby
Addresses anywhere in the AL1 and AL3 postcode districts can book drive unit replacement through us. The engineer who attends works under our management and travels to the site. There is no branch in St Albans, so the price, the booking and the paperwork all come from one place.
Supermarkets and larger stores in and around St Albans often trade long hours, so work on their entrances is usually planned for early mornings or late evenings. Where a store has more than one entrance, keeping one in use while the other is worked on is part of the plan.

What to think about for drive unit replacement in St Albans
- Business parks and office blocks in St Albans with several identical doors can replace operators in phases, keeping at least one entrance open at all times.
- 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.
- Hospitals and care homes in St Albans may need an alternative entrance during the changeover. Plan signs and step-free access for wheelchair users before work starts.
- Older shopfronts in St Albans may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- Listed buildings and conservation areas in St Albans make it attractive to keep the existing frame. A new operator inside the existing header changes little that can be seen.

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 St Albans 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.
Send the make and model from the operator cover of your door in St Albans, and we will arrange a survey at no cost for a replacement drive unit.
Drive unit replacement in St Albans: questions
What if the frame of our door in St Albans 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.
What do you charge for drive unit replacement in St Albans?
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 St Albans confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
Do you provide paperwork for the converted door in St Albans?
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.
Can the replacement in St Albans 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 do you need from us for parking and access in St Albans?
Somewhere for the engineer's van as close to the entrance as possible, and a clear working area around the door. If parking is restricted, loading rules apply or the site has security procedures, tell us when you book. Those details go into the plan so the visit is not held up on the day.
What is the lead time for drive unit replacement in St Albans?
Lead times depend on the door type and what has to be made to order. As a guide, operators and accessible door kits are typically two to four weeks from order, and complete sliding entrances typically four to eight weeks from drawing approval. Curved, revolving and hermetic doors usually take longer. The expected lead time is stated in your quote.
Which building regulations apply to a new automatic entrance in St Albans?
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.
