What changes the cost of a porch?

What a porch price is made of

A porch is a small building in its own right. Even a modest one has foundations, a floor, walls, a roof, windows and a door, and it joins onto the front of the house. For a home in Cheshire, a porch quote usually covers groundwork and foundations, the base and floor, brick or block dwarf walls, the frame and glazing, the roof, the outer door, any electrics such as a light, guttering, and making good where it meets the house.

QuoteZila is starting in Cheshire, with Crewe, Nantwich and Sandbach among the first towns, and anyone in the UK can post a job. We have not printed a porch price. We could not find two dated public sources that agree on a figure, so a number here would be a guess. This guide sets out what changes the price and which limits to check before you ask for quotes.

Types of porch

Porches are built in several ways, and each is priced differently:

• A canopy. A roof over the front door with no walls. Small, and often simpler to arrange.
• A brick porch. Brick or block walls, a tiled or slate roof, and windows and a door set into the walls.
• A glazed porch. Low brick walls with uPVC, aluminium or timber framed glazing above, and a lightweight or tiled roof.
• A fully glazed porch. Glass from floor to roof, sometimes on a low base.
• A timber porch. An oak or softwood frame, open or enclosed, often chosen for older or country houses.

Ask installers to describe the type they are quoting for. A builder pricing brickwork and a porch company pricing a glazed unit will not produce comparable totals unless the design is the same.

Planning permission limits

The Planning Portal says adding a porch to any external door of a house is usually permitted development, which means it does not need a planning application, if all of these apply ^[S1]:

• the ground floor area, measured externally, is no more than three square metres
• no part of the porch is higher than three metres above ground level
• no part of the porch is within two metres of a boundary of the house and a highway

The Planning Portal says these rights apply to houses, not flats or other buildings, and that an article 4 direction can remove them ^[S1]. A listed building or a conservation area also needs checking. If your design goes beyond any of those limits, ask the council before you commit to a quote.

Those size limits are about planning, not building regulations. The Planning Portal points out that the three square metre planning figure and the 30 square metre building regulations figure are separate tests ^[S2].

Building regulations

The Planning Portal says a porch built at ground level with a floor area under 30 square metres is normally exempt from building regulations, provided several conditions are met ^[S2]. Those conditions include:

• the glazing and any fixed electrical installation meet the relevant parts of the building regulations
• the existing front entrance door between the house and the porch stays in place
• if the house has ramped or level access for disabled people, the porch does not make it worse

If you want to take out the front door to make the porch part of the hallway, or build a much bigger porch, the exemption may not apply. Ask building control before the work starts, not after.

FENSA says its scheme does not cover windows and doors in new porches ^[S3]. That means the glazing paperwork you may be used to from replacement windows does not automatically apply. Ask the installer how they will show the glazing meets the rules.

What changes a porch quote

If one quote leaves out foundations or the porch door, it is not quoting for the same porch.

Electrics, drains and things in the way

Before a porch is built, check what is already on that wall. Gas meters, electricity meter boxes, outside taps, drains, manholes and airbricks can all sit at the front of a house, and each can change the design or add work. A manhole or drain under the planned porch may need to be moved or have an access cover inside the porch.

If you want a light, a socket or a doorbell in the porch, that is electrical work. Ask who will do it and how it will be certified. Do not add a circuit or extend wiring yourself.

Ask the builder to note any meters, vents or drains on a sketch. If a meter would end up inside the porch or in the way, ask the builder who arranges moving it, because that is not usually something a builder can do alone.

How the build usually runs

A brick or glazed porch is a short building job, but it still happens in stages, and each stage needs the one before it finished. A typical order is:

1. Setting out the porch on the ground and checking the size against the drawing.
2. Digging and pouring the foundations.
3. Building the base, the floor and any dwarf walls.
4. Fitting the frame, the roof structure and the roof covering.
5. Fitting the glazing and the outer door.
6. Electrics, gutters, sealing and making good.

The front door of the house usually stays usable for most of the job, but there may be days when access is awkward. Ask the builder how you will get in and out, where materials will be stored, and whether a skip is needed on the drive or the road. A skip on the road may need a permit from the council, so ask who arranges that.

Weather affects groundwork and roofing. Ask what happens if rain delays the job, and whether the price is fixed regardless of how many days it takes.

Jobs you might post

These are examples, not taken from real job posts.

• "Would like a small brick porch over the front door, roughly two metres wide by one metre deep, to match the house."
• "Want to replace an old timber porch with a glazed porch on low brick walls."
• "Front door canopy needed. Something simple to keep the rain off the step."

Give rough measurements, say what the house is built from, and include photos of the front of the house showing the door, windows, meters and any drains or manholes.

How to compare porch quotes

Citizens Advice says a quote is a fixed price and an estimate is a guess, suggests written quotes from at least three traders, and suggests not agreeing to a deposit above 25% ^[S4]. Ask each builder or installer to list:

1. The porch type, size and external floor area.
2. The foundations and base.
3. Walls, roof and glazing materials.
4. The outer door and lock.
5. Electrics, gutters and drainage.
6. Making good where the porch meets the house.
7. How planning and building regulations have been checked.
8. Whether VAT is included, and how payments are staged.
