A porch is a small enclosed structure built over a front or side door, adding a weatherproof entrance space for coats, shoes and deliveries, improving security and reducing draughts and heat loss from the house.
We offer a new porch across Hertfordshire, and Potters Bar is one of the places we cover, along with nearby Hadley Wood, Barnet and East Barnet. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in the East of England it sits within £3,700–£8,400 including VAT.

Building in Potters Bar
Hertfordshire is home to the first garden cities, Letchworth and Welwyn Garden City, and the post-war new towns of Stevenage, Hatfield and Hemel Hempstead. Watford and St Albans have Victorian terraces and Georgian streets, interwar semis line the commuter suburbs, and brick-and-flint cottages appear in Chiltern villages to the west.
Generally dry with chalk and clay soils; clay areas can move in long dry spells, and mature trees near houses need considering for foundations.
That mix of housing shapes how we approach a new porch in Potters Bar: the age and construction of your home affect the materials, the method and, in the end, the price.
Permissions for a new porch in Potters Bar
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Potters Bar comes under England, covered below, and we raise any questions with the council before your quote is finalised.
In England, a porch is usually permitted development if its ground floor area is no more than 3 m², no part is higher than 3 m, and it is at least 2 m from any boundary with a road.
Small porches at ground level are usually exempt from Building Regulations if the front door stays in place between porch and house, but safety glazing and any electrics must still comply.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
A free survey comes first. It gives us what we need to price a new porch properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Your fixed price
After the survey we send a quote for a new porch that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
On site to finish
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
How we work
Porches in Potters Bar: questions
How much does a porch cost?
A typical enclosed porch of 2–3m² costs £3,700–£8,400, including foundations, walls, roof, windows and a new door. A uPVC porch on a dwarf wall sits at the lower end, while a fully brick-built porch with a tiled roof costs more. Open canopies cost less. The door specification and moving drains or meters also affect the price. We confirm a fixed price after the survey.
What if there is a gas meter or drain where the porch will go?
A gas or electric meter box or a drain in the porch area does not usually stop a porch being built, but it affects the design and cost. Meters may need moving by the supplier, which takes time to arrange. Manholes can sometimes be enclosed with a sealed cover, depending on the drainage. We check these details at the survey and include them in the quote.
Do you cover Hadley Wood, Barnet and East Barnet?
Yes. As well as Potters Bar, we cover Hadley Wood, Barnet and East Barnet and the rest of Hertfordshire. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
How long does it take to build a porch?
Building a porch usually takes one to two weeks on site. Foundations and base go in first, then the brickwork, roof, windows and door. uPVC and aluminium porches are often quicker because the frames are made off-site, while brick-built porches with a tiled roof take a little longer. Frames and doors are made to measure, so allow a few weeks' lead time before starting.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
