Covering Hertford and nearby
Homes, businesses and public buildings throughout the SG13 and SG14 postcode districts can arrange drive unit replacement with us. We are the contracting party and organise every visit; the engineer, who works under our management, travels in to Hertford for the job rather than working from premises in town.
GP surgeries, dental practices and pharmacies in Hertford often serve older patients and people with limited mobility. A low-energy swing operator, or a gentle sliding door with a push pad, can make a real difference at entrances like these.
Nearby towns we also list for drive unit replacement (straight-line distance): Ware (2.4 miles), Hoddesdon (3.7 miles), Welwyn Garden City (5.5 miles), Hatfield (6.6 miles), Cheshunt (6.9 miles), Waltham Abbey (8.2 miles).
What to think about for drive unit replacement in Hertford
- Older shopfronts in Hertford may have headers made for discontinued operators. Adapter plates usually allow a new drive unit to fit, which the survey confirms before you commit.
- 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.
- 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.
- 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.

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 Hertford 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.

Drive unit replacement in Hertford: questions
Will you remove the old operator from our premises in Hertford?
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.
How much should I budget for drive unit replacement in Hertford?
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 Hertford confirms the price as a fixed, itemised written quote, and the guide price tool gives you a range before anyone visits.
What if the frame of our door in Hertford 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.
Do you provide paperwork for the converted door in Hertford?
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.
What is the lead time for drive unit replacement in Hertford?
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.
Can automatic doors be fitted to a listed building in Hertford?
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 businesses in Hertford 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.
