Why Fortress

Built on the standards and official data planners trust.

Every report cites the current guidance for its discipline and draws from the same authoritative sources your case officer uses — so there’s nothing for them to send back.

Current guidance, cited

Reports reference the live standard for each discipline — BRE BR 209 (2022), Environment Agency flood guidance, Defra LAQM.TG(22), Part L 2021 and the Environment Act 2021 — never a dated template.

Live official data

We pull from the same sources planners rely on: Environment Agency flood maps, Defra background concentrations, Ordnance Survey referencing and site-specific solar data — matched to your exact site.

Written to be accepted

Clear methodology, the calculations officers look for, a mitigation plan and recommended conditions. Backed by our amend-or-refund guarantee if an authority ever rejects one.

One team, six disciplines

Bundle daylight, flood, air quality, energy, sustainability and Building Regs and the documents cross-reference cleanly — one point of contact, one co-ordinated submission.

Fixed fees, no surprises

Every fee is quoted before you commit and there’s no advance payment. Review the finished report first; you only pay when you’re happy with it.

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.

The energy statement hit the London 35% carbon target with a heat pump and rooftop solar — exactly what the validation checklist asked for. Straightforward from start to finish.

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

FAQ

Questions clients ask before they commission.

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 reference or your architect’s drawings and we’ll tell you exactly which reports apply — daylight, flood risk, air quality, energy, sustainability or Building Regulations — and quote for them.
Are your reports accepted by local planning authorities?
Yes. Each report is written to the current standard for its discipline and to what councils expect at validation. If an authority ever rejects a report we prepared, we amend it free of charge — or refund you in full.
Do you cover my area?
The daylight, air quality, energy and sustainability services cover every UK local authority. The automated flood risk assessment is for sites in England, where it uses live Environment Agency data.
How much do the reports cost, and do I pay upfront?
Fees are fixed and quoted before you commit, and there’s no advance payment. The flood risk, air quality, energy and sustainability reports let you review the full report before you pay; bespoke daylight and Building Regs work is quoted per project.
How quickly will I get my report?
The automated flood risk, air quality, energy and sustainability reports are ready in minutes. Bespoke daylight and Building Regulations work is typically 3–5 working days from receiving your drawings.
What if my application was already refused?
We regularly prepare reports to support resubmissions and appeals. Send us the officer’s reasons for refusal and we’ll address them directly in a report designed to overcome the objection.
