Covering Hertford and nearby
Homes, businesses and public buildings throughout the SG13 and SG14 postcode districts can arrange automating an existing door 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.
Many buildings in Hertford are older, with timber frames, thick walls, steps or uneven thresholds. These affect where an operator and sensors can go, and the engineer checks them on site before anything is fitted or adjusted.
Nearby towns we also list for automating an existing door (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 automating an existing door in Hertford
- Power is needed at the head of the door. If there is no supply close by, an electrician will need to run one, ideally hidden in trunking or the wall.
- Older buildings in Hertford often have heavy timber doors on floor springs. Some floor springs can be adapted, but many need replacing with hinges, which adds to the cost.
- Listed buildings and conservation areas in Hertford may need consent for an operator on an original door. Mounting it on the inside face usually keeps the street view the same.
- Glass in a door that will be automated should be safety glass. Older doors in Hertford may have panes that need replacing before the work goes ahead.
- Think about how the door is locked. If it is locked by key every night, an electric lock or keep may be worth adding so the door can be secured without switching the operator off.

Standards and rules in England
Under the Equality Act 2010, service providers and employers must make reasonable adjustments for disabled people, which can include altering a physical feature such as a heavy entrance door. Fitting an automatic door helps, but does not on its own guarantee those duties are met.
Building regulations guidance in England (Approved Document M, Volume 2) says a powered opening system should be used where a self-closing entrance door would need more than 30 N at the leading edge to open, or more than 22.5 N between 30° and 60°, and expects external doors used by the public in new buildings to give at least 1000 mm of effective clear width.
How it works
- Start with a short enquiry. Use the form, phone or email. Tell us whether the work is a new door, an upgrade or an opener for a home, and we arrange the next step for your site in Hertford.
- Measured survey. The free survey confirms what will fit and what the entrance needs: opening width, door type, activation, safety sensors and behaviour on power loss or fire alarm, matched to how the building is used.
- Written price, no surprises. A fixed, itemised quote sets out the specification, the work involved, the expected lead time and the warranty terms. You can ask questions or change the specification before accepting it.
- Installed and commissioned. The door is installed with as little disruption as possible, then set up and tested for its hazard zones. Before leaving, the engineer explains the controls and hands over the documents for your records.
Ask us to look at the doors at your premises in Hertford. If a retrofit makes sense, you get a fixed quote, and if replacement is better, we explain why.
Automating an existing door in Hertford: questions
Can you automate the existing doors at our building in Hertford?
In most cases, yes. We check each door at a free survey, including the hinges, frame, glass, locks and power, and then quote a fixed price. If a door is not a good candidate, we explain why and what it would take to fix it, or quote a replacement instead.
What is the guide price for automating an existing door in Hertford?
Our guide starts from £1,795 excluding VAT (per door), the same guide price we use across the UK. For homes that is from £2,154 including VAT. 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.
Can you automate a fire door at our premises in Hertford?
Usually, using an operator designed for fire doors and wired to the fire alarm so the door closes when the alarm operates. We check the door's rating and condition first. A fire door that does not close and seal properly needs repairing before an operator goes on.
Do you provide the paperwork for an automated door in Hertford?
Yes. Motorising a manual door brings manufacturer's duties for the completed powered door, so when we automate a door we provide the risk assessment, test record, settings and conformity paperwork at handover. Keep them with your building records, as insurers, inspectors and future service engineers may ask to see them.
Is there a warranty on automating an existing door?
Yes. The warranty terms for the equipment and the installation are set out in your written quote, so you can see exactly what is covered before you accept. Keeping the door serviced at the recommended intervals helps keep it in good order, and the quote explains any conditions that apply to the warranty.
How are payments structured for work in Hertford?
Payment stages are set out in the quote before you accept it. Larger or made-to-order jobs may involve a deposit and a balance on completion, while smaller jobs may be invoiced once the work is finished. Nothing is charged for the survey itself, and the terms you accept are the terms that apply.
Which building regulations apply to a new automatic entrance in Hertford?
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.
