Book conservatory consultancy.

A professional conservatory consultancy service ensures your new room is more than just a "glass box." Expert advice helps you choose the right materials and design to ensure the space remains usable year-round, avoiding the common pitfalls of poor temperature control and planning disputes.

What Does the Work Involve?

• Site Assessment: Evaluating the proposed location for ground stability, drainage access, and proximity to boundary lines.
• Solar Orientation Analysis: Advising on glazing types based on whether the conservatory faces North (cold) or South (prone to overheating).
• Design & Material Selection: Comparing uPVC, aluminium, and timber frames, alongside roofing options like glass, polycarbonate, or lightweight tiles.
• Regulatory Check: Determining if the project falls under "Permitted Development" or requires a full planning application.
• Structural Integration: Assessing how the new structure will join the existing house, including damp-proofing and lintel requirements.
• Utility Planning: Mapping out requirements for heating, lighting, and ventilation to ensure the room meets building regulations for habitability.

Typical Costs

Prices vary significantly based on your location in the UK and the complexity of the design. While some installation companies offer "free" consultations, these are often sales-focused; independent consultants charge a fee but provide unbiased structural and regulatory advice.

How Long Does It Take?

• Initial Site Visit: 1–3 hours depending on the size of the property and site access.
• Feasibility Report: 3–5 working days following the site visit.
• Full Design & Technical Drawings: 2–3 weeks, depending on the number of revisions required.
• Planning Permission Process: 8–12 weeks if a full application is required by the local council.

DIY or Professional?

While a confident DIYer might manage the construction of a small "kit" conservatory, the consultancy and design phase should always be professional. In the UK, failing to adhere to Building Regulations or Planning Permission can result in an enforcement notice requiring you to demolish the structure.

Professional consultants ensure your conservatory meets Part L (Thermal Efficiency) and Part A (Structural Safety) of the Building Regulations, which is essential when you eventually come to sell your home.

Choosing the Right Tradesperson

• Check if they are members of a recognised body like FENSA, CERTASS, or the Glass and Glazing Federation (GGF).
• Ensure they have specific experience with the type of structure you want (e.g., Orangeries vs. Victorian conservatories).
• Verify their Professional Indemnity insurance to protect against design errors.

• Will this design be exempt from Building Regulations, or will I need a formal completion certificate?
• How do you plan to manage "solar gain" to prevent the room from overheating in summer?
• Can you provide a portfolio of similar projects you have designed in this local area?
• Are you an independent consultant or tied to a specific manufacturer?

UK Regulations

• Permitted Development: Many conservatories don't need planning permission if they meet specific size and height limits (e.g., not exceeding 50% of the land around the original house).
• Building Regulations: Generally exempt if under 30m², at ground level, and separated from the house by external-grade doors. However, heating and glazing must still meet efficiency standards.
• Part L Compliance: Relates to the "U-value" of the glass; modern installs must meet strict insulation targets.
• Build Over Agreements: If you are building over or near a public sewer, you must get permission from your local water authority (e.g., Thames Water, United Utilities).

Common Problems

• Poor Thermal Performance: Using cheap polycarbonate roofing often leads to a room that is unusable for six months of the year.
• Foundations: Standard 600mm trenches may be insufficient if there are nearby trees or clay soil, leading to structural cracking.
• Drainage Issues: Building over manholes without proper access or "build-over" agreements can lead to legal and maintenance nightmares.
• Ventilation: Lack of adequate roof vents or "trickle vents" in windows often results in severe condensation and mould growth.
