Porch Costs UK — What to Charge for Porch Supply and Build in 2026

A new porch is one of the most common builder jobs in the UK — a defined scope, a clear customer brief, and a relatively short programme. But porch prices vary enormously: a simple open canopy can be done for under £1,500, while a full brick-built enclosed porch with a composite door and tiled floor can reach £10,000 or more. Quoting accurately means understanding which type of porch the customer actually wants, assessing ground conditions, checking planning status, and pricing each element — foundations, frame or brickwork, roof, door, and finishing — as named line items. This guide covers 2026 supply-and-build costs for every porch type, the planning and building regulations rules that determine what you can build without permission, and the upsells that reliably increase job value.

Porch Types and Full Build Costs (2026)

The prices below are fully installed supply-and-build costs to the homeowner, covering groundworks, structure, roof, and front door (uPVC unless noted). Electrical and internal floor tiling are excluded — see separate sections below.

uPVC or aluminium lean-to porch (frame and glazing)

The lean-to uPVC porch is the most affordable enclosed porch option. A glazing kit — pre-fabricated uPVC or aluminium frame with polycarbonate or glass panels — is erected on a simple concrete strip foundation, with a lean-to roof pitching back against the house wall. Polycarbonate roofing is the budget option; toughened glass roofing is more durable and aesthetically superior and adds £300–£600 to the cost. uPVC lean-to porches do not require a bricklayer — a competent carpenter or general builder can erect the frame in one to two days.

Brick and tile porch with uPVC door

The brick-built porch is the most popular upgrade for homeowners looking for something that matches the existing house construction. Brick walls to DPC level, then brick or rendered upper walls with a pitched tiled roof to match the house — this is the look most customers imagine when they ask for “a proper porch.” It requires a bricklayer, carpenter for the roof structure, and a roofer or the same bricklayer to tile. The programme is one to two weeks depending on size and drying times.

Timber framed porch with tiled roof

A softwood or hardwood framed structure with a tiled or slate roof. The frame is erected on concrete strip foundations, clad with weatherboarding, shiplap, or feather-edge boards, and roofed with tiles or slates to match the house. Glazed panels or windows can be incorporated in the sides. Timber framed porches suit cottages, rural properties, and older houses where a brick porch would look out of character. The programme is similar to a brick porch — one to two weeks — but requires a carpenter rather than a bricklayer as the primary trade.

Oak framed porch (feature)

£6,000–£15,000+ depending on size and specification. An oak frame porch is a feature element — exposed structural oak posts and beams, often with a clay tile or natural slate roof and open or part-glazed sides. The cost range is wide because oak frame work is largely bespoke: the frame is usually fabricated off-site by a specialist oak framer and installed in one or two days. The high end of the range covers large open porches on high-specification country homes. Oak frames are not generally painted or finished — the natural greying of oak over time is part of the aesthetic. Confirm this with the customer at survey; some expect treatment or staining.

Open canopy porch (no enclosure)

£800–£2,500. An open canopy — a roof structure over the front door with no side glazing or walling — is the most affordable option and the right solution where the customer simply wants weather protection at the front door without the cost of a full enclosure. Canopies range from simple GRP moulded units fixed to the wall (£800–£1,500 supply and fit) to bespoke timber or steel canopies with lead flashings and tiled roofs (£1,500–£2,500). Open canopies sit within the footprint of the house for planning purposes and do not typically trigger planning or building regulations requirements.

What's Included in a Porch Build

A full enclosed porch build — whether brick, timber, or uPVC — typically covers the following elements. Price each as a named line item so customers understand what they are buying:

• Strip existing front path or step: Remove and dispose of existing path surface, step, or existing porch structure. Allow one to two skips for a typical job.
• Strip existing porch if replacing: Demolish and remove existing structure. Price separately if the existing porch is brick-built — demolition of a brick porch can take half a day and generates significant rubble.
• Concrete strip foundations (50–75 cm deep): Excavate and pour concrete strip foundations around the porch perimeter. Depth depends on ground conditions — clay ground may require deeper foundations.
• Brickwork to DPC: First course or two of brickwork from foundation to damp proof course level, matching the house brickwork where possible. Includes DPC installation and ground-level step.
• Frame, glazing, or timber structure: Supply and erect the main porch structure — uPVC frame and panels, timber frame and cladding, or brick walls as specified.
• Roof (tile or flat GRP): Roof structure, tile battens, felt, and tiles or slates to match house; or flat GRP fibreglass roof. Includes all flashings and lead work to the house wall junction.
• Front door (uPVC included): Standard uPVC front door with cylinder lock. Add £600–£1,500 for a composite door upgrade.
• Internal floor tiles (optional add-on): Porcelain or ceramic floor tiles to the internal porch floor. Add £200–£500 depending on tile choice and floor area.
• Electrical socket or light (optional add-on): First-fix and second-fix electrical for a single socket and/or porch light. Add £150–£300 depending on proximity to consumer unit and cable run.

Planning Permission Rules for Porches

Most porches are built under Permitted Development Rights — meaning they do not need a formal planning application. However, the permitted development rules for porches are specific and the conditions must all be met simultaneously. Make it a standard part of your survey process to check each condition before confirming to a customer that planning is not required.

A porch is permitted development if all of the following apply:

• Floor area not exceeding 3 m²: This is the internal floor area of the porch, measured to the inside faces of the walls. A 2 × 1.5 m porch is exactly 3 m² — at the limit. Any porch over 3 m² requires planning permission.
• Maximum height 3 m: Or 4 m if the roof is a dual pitched (ridge) roof and the porch is more than 1 m from the property boundary. A standard single-storey lean-to porch will easily meet this.
• Not forward of a wall forming the principal elevation fronting a highway: The porch cannot project beyond the front building line of the house where that elevation faces a road. On most terraced and semi-detached houses, this means you cannot build a porch that extends beyond the existing front wall line if the house faces a road directly.
• Not within a conservation area: Conservation area properties require planning permission for any porch that alters the character of the front elevation.
• Not on a listed building: Listed Building Consent is required for any works affecting the character of a listed building — including a new porch on the front elevation.

Always recommend the customer checks with their local planning authority if there is any uncertainty — particularly on corner plots (where the “principal elevation” is not always obvious), on properties in areas with Article 4 Directions removing permitted development rights, or on any property in a conservation area or AONB.

Building Regulations: When They Apply

Porches are among the few building projects that can be exempt from building regulations entirely — but only if specific conditions are met:

• Exempt (no building regs required): A porch is exempt from building regulations if it is at ground level, its floor area does not exceed 30 m² (note: this is a separate, more generous limit from the permitted development 3 m² planning limit), and there is an external-quality door between the porch and the rest of the house. The existing front door between the hallway and the porch must remain in place, or a new door of equivalent specification must be fitted. This means the porch is thermally separated from the heated house — it is effectively an unheated buffer zone. Glazing in the porch is not required to meet Part L thermal standards in this case.
• Building regulations apply: If the existing front door between the hall and porch is removed — making the porch thermally connected to the main house — then the porch becomes part of the building envelope. Building regulations Part L (energy efficiency) apply to the glazing and roof, and Part A (structure) applies to the foundations and structural elements. A building control application or a competent person self-certification (via FENSA or Certass for the glazed elements) is required.

In practice, most porch builds leave the original hallway door in place — which keeps the porch exempt from building regs. Confirm this with the customer at survey and note it in your quote documentation. If they want to remove the internal door, price the building regs application separately (£100–£200 for a full plans application to the local authority, or covered by FENSA/Certass registration if you are registered).

Labour Content and Day Rates

Porch builds are multi-trade jobs. The programme and crew required depends heavily on porch type:

uPVC lean-to porch

Typically 3–5 days total. Day 1: groundworks and foundations. Days 2–3: frame erection and roof installation. Days 4–5: door hanging, finishing, and snagging. A bricklayer's mate or labourer handles the groundworks; a carpenter erects the frame. A two-person crew (carpenter and labourer or bricklayer's mate) can complete a small lean-to porch in three to four days.

Brick-built porch

Typically 1–2 weeks. Allow time for foundation concrete to cure (minimum 48 hours before brickwork commences), brickwork drying time between lifts, and roof structure installation separately from brickwork. A bricklayer leads; a carpenter handles the roof structure and door hanging. A single bricklayer and labourer can build a small brick porch in five to eight working days.

Day rates (2026)

London and South East day rates typically sit at the upper end of each range. Northern England and Scotland generally sit 10–15% lower.

Quoting Process: What to Check at Survey

A porch survey should cover the following before you produce a price. Skipping any of these checks risks either underpricing the job or producing a price that changes after contract — the most common source of customer disputes on porch builds:

• Check planning status: Is the property listed? Is it in a conservation area? Does the proposed porch exceed 3 m²? If any of these apply, planning permission is required. Do not assume; ask directly and check the local planning authority online if there is any doubt.
• Measure the existing front door opening and path width: The porch width is constrained by the front door opening and the available path width. Measure the reveal dimensions of the existing front door. The porch frame width needs to accommodate the existing door — or a new door in a new position — within the porch.
• Assess ground conditions: Look for signs of clay soil — the characteristic blue-grey or orange-brown clay visible at the edges of the path, or evidence of movement in adjacent paths or walls. Clay ground requires deeper foundations (75 cm rather than 50 cm) and potentially a wider strip — add £200–£500 to the groundworks element on confirmed clay.
• Note services near the front of the house: Gas meter boxes, electric meter boxes, water stop taps, and drainage inspection chambers near the front door can all complicate foundation excavation. Identify any services within 600 mm of the proposed foundation line and price additional work to divert or protect them if required.
• Check the existing front door: Is the customer keeping the existing internal door? If yes, building regs are typically not triggered. If they want to remove it, price the building regs compliance separately. Is the existing door in good condition and correctly hung? If the porch will enclose it, the customer may want it replaced — price a new composite or timber internal door as an optional add-on.

Upsells: What to Offer on Every Porch Job

A porch enquiry typically comes from a customer investing in their home's front elevation. The incremental cost of add-ons relative to the base job is modest, and customers who are already spending £4,000–£8,000 on a porch will often spend another £300 for a meaningful improvement. These upsells should be offered as named line items on every porch quote:

Security light (+£100–£200 fitted)

A PIR security or smart LED security light above or beside the new porch door is the single most practical upsell on any porch job. The electrician is already on site. The cable run is short. The customer gets a meaningful security and convenience benefit for a small incremental cost. Ask about it on every job: “Would you like us to include an external security light on the porch while we're running the electrical?” Almost all customers will say yes.

Ring doorbell or smart lock (+£150–£350 fitted)

A Ring video doorbell or Yale smart lock fitted as part of the porch installation is an increasingly common request. Supply-and-fit pricing: Ring Doorbell Wired £150–£200 fitted (requires a transformer or doorbell transformer in the consumer unit if the property has no existing doorbell wiring); Yale smart lock £200–£350 fitted. Present both as options at survey — customers who are building a new porch are thinking about home security and these products align directly with that mindset.

Tiled internal floor (+£200–£600)

Porcelain or ceramic floor tiles in the porch interior are a significant aesthetic upgrade over a plain concrete floor. The cost range depends on tile choice and floor area. Standard 600 × 600 porcelain tiles on a 3 m² porch: £200–£350 supply and lay. Large-format tiles (e.g. 900 × 900), natural stone, or encaustic tiles that match the hallway interior: £400–£600 or more. If the customer is having the hallway tiled at the same time, price the porch floor as a continuation of the same tile and layout — it looks better and saves on waste.

Composite door upgrade (+£300–£800 vs uPVC)

If the base quote includes a standard uPVC front door, offer the composite door upgrade as a named option. A composite door — GRP or timber core with a moulded skin and multi-point locking — is visually superior to uPVC, thermally better, and more secure. Customers who are spending £5,000 on a brick porch will often spend an extra £500 for a door that looks appropriate for the build quality. The composite door upgrade is your highest strike-rate upsell on porch jobs: ask about it on every quote.

Oak frame feature upgrade (+£1,500–£5,000)

If the customer is building a brick or timber porch and has a reasonable budget, offer an oak frame feature element — exposed oak posts at the front corners of the porch, an oak bressumer beam over the opening, or an oak canopy over the door within a brick porch structure. This is a premium upgrade that transforms the kerb appeal of a standard brick porch into something that looks architecturally considered. Price it as a named option: £1,500 for a simple oak post-and-bressumer front feature; £3,000–£5,000 for a more substantial oak frame element integrated into a larger porch structure.

Tracking Which Channels Drive Your Porch Enquiries

Porch jobs are mid-value, relatively high-frequency for a general builder or bricklayer. They tend to come from homeowners who are actively searching — “porch builder near me” or “new porch cost” — so paid search and a well-optimised Google Business Profile are the primary channels. Door drops and van signage in residential areas also produce porch enquiries, particularly in the spring when homeowners are planning front elevation improvements.

The risk with porch jobs is spending money on lead generation channels that produce enquiries but not contracts — price-shoppers who collect three quotes and go with the cheapest. Knowing which channel produces your highest-converting, highest-value porch jobs (rather than just the most enquiries) is the metric that matters. Trade2Base records enquiry source against job value and conversion rate so you can see which channels produce porch contracts versus enquiries that never convert — and make informed decisions about where to concentrate your marketing spend.
