Mortgage Brokerage
How one mortgage brokerage hit zero compliance incidents — and kept them there
Inconsistent EPC data across 85 advisers caused two near-misses. A single CRM integration standardised every case from day one.
The challenge
This brokerage had grown steadily into a network of 85 independent mortgage advisers across 12 offices. Each adviser operated semi-autonomously — their own client relationships, their own working style, and, increasingly, their own approach to sourcing property data.
When lenders began tightening requirements around environmental risk disclosure — particularly EPC ratings and flood zone checks — the inconsistency became a liability. Some advisers were pulling EPC data from outdated PDFs they'd saved months earlier. Others were skipping it entirely when the certificate wasn't easily accessible. Two compliance incidents in twelve months forced a conversation at board level.
The problem wasn't the advisers — it was the absence of a system. There was no standardised data pull, no single source of truth, and no way to verify that the property intelligence on any given case was current. With lenders becoming more demanding and the regulatory environment tightening around energy performance and environmental risk, that gap was unsustainable.
They needed a way to make every adviser work from the same data, without changing the CRM system they'd invested in or rebuilding their workflow from scratch.
"We had two near-misses where outdated EPC data nearly caused lender rejections. Since integrating Homedata, our data is consistent across every adviser, every case."
The solution
A "property intelligence pull" built into their CRM — triggered automatically when a case is opened, before any adviser touches the file.
Their development team built a webhook integration that fires when a case is opened in their CRM. The property address is resolved to a UPRN, and five Homedata endpoints are called in parallel: EPC, flood risk, radon, coal mining risk, and property record.
The EPC endpoint (/api/epc-checker/{'{uprn}'}/) returns the current energy rating (A–G), efficiency score, potential rating, and floor area — always the most recent registered certificate, never a cached PDF. The environmental risk endpoints — flood risk, radon potential, and coal mining subsidence — complete the lender disclosure requirements in three more calls.
By the time an adviser opens a case, all five data points are already populated. There's nothing to look up, nothing to forget, and no version of the data that's more than hours old. All 85 advisers now work from identical, standardised property intelligence on every instruction.
/api/epc-checker/{'{uprn}'}/
Current energy rating A–G, efficiency score, potential rating, floor area. Always live — never cached.
/api/risks/flood_risk/?uprn=
River flood risk, surface water risk, risk bands. Required by an increasing number of lenders.
/api/risks/radon/?uprn=
Radon potential percentage and risk band. Flags affected areas for lender disclosure.
/api/risks/coal_mining/?uprn=
Subsidence risk for properties in historic mining areas.
/api/v1/properties/{'{uprn}'}/
Bedrooms, property type, floor area, tenure, council tax band — the verified property facts.
The results
Integration
Five API calls fired in parallel on case creation: EPC (1 call), flood risk (1 call), radon (1 call), coal mining risk (1 call), property record (1 call). Total: 5 calls per case, all returning in under 400ms. The integration runs as a background job on their CRM's case-creation webhook — advisers see the data pre-populated when they open the file, with no wait time. Their team built the initial integration in under a week; the full adviser rollout took one further week via a short internal training session.
