Our neighbour objected that our extension would block their light. The daylight & sunlight report showed every window passed the BRE test and the case officer dismissed the objection. Worth every penny.

The council made a flood risk assessment a condition of approval. Fortress turned it round with the SuDS drainage strategy included, and the condition was discharged first time.

As a planning consultant I now use them across daylight, flood risk and air quality. The reports read exactly like the big-name consultancies’ work at a fraction of the fee.

Our site fell inside an AQMA and we needed an air quality assessment quickly. Clear, thorough, and the officer accepted the methodology without question.

Commissioned the daylight report and the flood risk assessment together. One point of contact, cross-referenced documents, and a discount on the combined fee. Very easy to deal with.

Refused first time round. Resubmitted with their report and got permission at committee. Should have started here.
FAQ

Answers, before you ask.

Still wondering? Drop us a line — every enquiry is answered as quickly as we can.

Ask us anything
Which report does my planning application need?
Your planning officer or the council’s validation checklist will list what’s required. If you’re not sure, send us the application details and we’ll tell you exactly which reports apply — daylight, flood risk, air quality, energy, sustainability or Building Regulations — and quote for them.
How quickly will I get my report?
The flood risk, air quality, energy and sustainability reports are generated in minutes from live official data. Bespoke daylight and Building Regulations work is typically 3–5 working days from receiving your drawings.
Do you really not take advance payment?
Correct. There’s no advance payment on any service — you review the finished work first and only pay when you’re happy with it.
Which standards do your reports follow?
Each discipline follows its current standard: BRE BR 209 (2022) and BS EN 17037 for daylight; Environment Agency guidance, NPPF/PPG and CIRIA C753 for flood risk; Defra LAQM.TG(22), IAQM and EPUK for air quality; Part L 2021 and SAP 10.2 for energy; the Environment Act 2021 and the London Plan for sustainability; Approved Documents A–S for Building Regs drawings.
Will my Local Planning Authority accept your report?
Our reports follow the current methodology for each discipline and cite every assumption. If an authority ever rejects a report we prepared, we amend it free of charge — or refund you in full.
Can I commission several reports at once?
Yes — many schemes need more than one. Commission them together and the documents cross-reference cleanly, the timeline shortens, and you get a discount on the combined fee.
