How to price conservatory installation jobs in the UK (2026 guide)

The UK conservatory market remains one of the most active sectors in home improvement, with homeowners spending an estimated £1.5 billion per year on new builds, conversions, and solid roof upgrades. Consumer tastes have shifted significantly: the era of the cold polycarbonate lean-to is giving way to thermally efficient solid tiled roofs, garden rooms, and orangeries that function as genuine living space year-round. For builders and glaziers who can price this work accurately and present quotes professionally, conservatory installation is a high-value, recurring pipeline of jobs — particularly in the £15,000 to £30,000 bracket where margins are strongest. This guide covers how to build pricing that reflects your real costs, how to handle the variables that swing conservatory quotes, and how to win more contracts in a market where buyers increasingly research prices online before calling anyone.

Conservatory Types and Base Prices

The conservatory market in 2026 segments clearly by roof style and structural form, each with its own cost profile and client expectation. A lean-to conservatory — the simplest single-pitch design that butts up against a house wall — is the entry point for most residential clients and prices at £8,000 to £15,000 fully installed, depending on size, glazing specification, and finish quality. A Victorian conservatory, with its characteristic multi-faceted bay front and ridge-height roof, prices at £10,000 to £18,000 for a standard 3.5 to 4.5 metre projection. An Edwardian conservatory — the square-fronted, maximally usable floor space option preferred by families — sits at £12,000 to £20,000 at equivalent size. A solid tiled roof conversion or new build with a tiled or slate-effect solid roof occupies the premium end: £15,000 to £28,000 depending on structural requirements, insulation specification, and whether an existing polycarbonate roof is being stripped. Garden rooms and orangeries with brick columns and flat or pitched roofs command £20,000 to £40,000 or more at the upper end of the specification range. These are supply-and-install prices including VAT, frames, glazing, base, electrics, and finishing — adjust your own numbers against your regional labour costs and supplier relationships.

Site Survey and Foundation Costs

The base and foundation are the elements most likely to generate cost surprises on conservatory jobs, and they must be assessed at survey rather than estimated from photos. A standard concrete strip foundation and slab base for a lean-to or Victorian conservatory on level ground with good soil conditions costs £1,500 to £3,000 for a 12 to 15 square metre footprint. On sloping ground requiring stepped or piled foundations, or where trial digs reveal poor soil or made-up ground, costs can reach £4,000 to £8,000 before the frame is even ordered. Drainage is the other survey variable: where the new base will cut across existing drainage runs, the cost of rerouting or benching manholes can add £500 to £2,000 to the project. An honest site survey that scopes these risks before quoting protects your margin and your relationship with the client. Quote a standard base price with a clear note that foundation costs are subject to site conditions — this is industry standard and clients who have done any research will understand it.

Glazing Specification and Roof Choices

Glazing specification is the single biggest driver of both quality perception and cost variation in conservatory pricing. Polycarbonate roofing is the lowest-cost option — 16mm bronze or opal polycarbonate panels cost £25 to £45 per square metre supplied, and a 15-square-metre roof section can be glazed for £500 to £800 in materials. However, polycarbonate offers poor thermal performance, significant noise in rain, and a lifespan of 10 to 15 years before degradation and discolouration set in. Glass roofing — self-cleaning laminated safety glass in aluminium or UPVC bar cap systems — costs £80 to £150 per square metre and dramatically improves the thermal and acoustic performance of the space. Solid tiled roofing systems such as Guardian, Ultraroof, or Supalite use an insulated lightweight structural frame overlaid with concrete or composite tiles: costs run from £120 to £200 per square metre installed and transform the conservatory into a room that meets Part L thermal requirements and can be used comfortably year-round. Side wall glazing should be specified as minimum A-rated or better energy-rated double glazing as standard — clients who are spending £15,000 on a conservatory should not be receiving C-rated glass, and any decent quote should specify the glazing energy rating explicitly.

Electrics, Heating, Blinds and Extras

The base conservatory price should always be presented as a structure-and-glazing price, with the following extras itemised clearly to avoid client assumptions about what is included. Electrical first fix and second fix — consumer unit spur, sockets, lighting, and any underfloor heating cabling — costs £600 to £1,500 depending on whether the client wants simple sockets and a light or a full specification with multiple circuits. Heating is the most frequent afterthought that turns into a dispute: if the conservatory is not connected to the central heating system, the client will call you back in October complaining it is unusable. Extension of the wet central heating system with one or two radiators costs £500 to £1,200 depending on pipe run length. A separate electric underfloor heating mat under a tiled floor costs £300 to £700 for a 12 to 15 square metre room. Roof and side blinds are a significant upsell: a full fitted blind system for a medium Victorian conservatory costs £1,500 to £3,000 supplied and fitted, and significantly improves comfort in summer. Tiled or porcelain flooring, if the client wants it laid, adds another £800 to £2,000 depending on tile specification and the size of the space.

Planning Permission Considerations

The majority of conservatory installations in England fall within permitted development rights and do not require planning permission, but the conditions are specific and must be checked at survey. Permitted development applies where the conservatory covers no more than half the area of land surrounding the original house, does not extend beyond the rear wall of the original house by more than three metres (or four metres for a detached house), is no more than four metres in height at the ridge, and is not on Article 4 land, in a conservation area, or on a listed building. Any project that falls outside these parameters requires a planning application, which adds £500 to £1,500 in fees and six to eight weeks to the project timeline in most local authorities. Building regulations approval is not required for most conservatories where the conservatory is separated from the house by an external quality wall with a door, and the roof is at least 75 per cent translucent. Solid roof conversions and garden rooms typically do require building regulations approval — factor in structural engineer fees of £400 to £800 and building control fees of £300 to £700 when pricing these projects.

Quoting Tips and Winning Conservatory Contracts

Conservatory clients almost always get three quotes, and the winning quote is rarely the cheapest. Research consistently shows that homeowners making a £15,000 to £25,000 purchasing decision weight trust, presentation, and clarity of specification more heavily than headline price. A professionally presented PDF quote that includes a CAD drawing or visualisation of the proposed structure, a clear breakdown of what is and is not included, your insurance and registration details, and a payment schedule with defined milestones converts at a meaningfully higher rate than a handwritten or emailed price. Specify the glazing energy rating, the frame profile and colour, the roof system brand and warranty, and the projected U-value — clients who have researched conservatories online will recognise and value this level of detail. Follow up at five days after submitting a quote with a brief message offering to answer questions or arrange a second visit: conservatory buyers often have a spouse or partner who was not at the initial survey and has questions that arise after you leave. Offering a show-home or reference visit — a previous customer who is happy to show their conservatory — closes hesitant buyers more effectively than any discount.

Trade2Base for Conservatory Quoting and Project Management

Trade2Base lets conservatory installers build and send professional, itemised quotes in minutes — with line items for structure, glazing, base, electrics, blinds, and any project-specific extras all visible to the client with clear descriptions. Quotes are sent via a branded client portal where the homeowner can review, comment, and approve — reducing the back-and-forth that delays conservatory contracts from being signed. Automated follow-up reminders chase quotes that have not been responded to at five and ten days, so nothing falls through the gaps during the decision window. Once approved, the project converts into a job with a payment schedule, so stage payments are collected automatically at deposit, frame delivery, and completion without manual invoicing.
