Home Services & Construction

Win the call, win the job, keep the customer.

Fifty One Degrees builds production AI for home-services and construction businesses: voice AI that answers every call and books the job.

A missed call is a lost job. Most of your best customers are hiding in data that is free, public and sitting untouched.

The problem

Where does a home-services business lose money?

Missed calls, lost jobs
“We can’t answer every call, especially after hours and in a cold snap.”
Each missed enquiry is revenue that goes to whoever picks up.
Cost that rises with volume
“Every new job adds the same admin, quoting and aftercare.”
When headcount scales with the book, margin never improves.
Best customers hiding in plain sight
“We market to everyone and chase the wrong leads.”
The signals that identify an ideal job, property type, age, location, are free and public, but unused.
Data trapped, decisions guessed
“Our numbers live in NetSuite, the CRM and spreadsheets.”
Nobody can say which channels, postcodes or engineers are actually profitable.
The Home Business Growth Stack

How does Fifty One Degrees grow a home-services business with AI?

The Home Business Growth Stackis Fifty One Degrees’ three-layer architecture for home-services and construction firms. Each layer feeds the one above it.

01
Data Foundation
Unify NetSuite, your CRM (Salesforce, HubSpot), field-management and web analytics into one reliable layer (dbt, BigQuery or Snowflake), so every other layer has clean inputs and the board pack builds itself.
02
Property Intelligence Layer
Enrich your customer and prospect data with free UK open data to find the right properties and people. See the detail below.
03
AI Automation Layer
Put AI to work on the front line and the back office: voice AI on the phones, agents on aftercare and compliance, and propensity-scored lead queues for the sales team.
The named asset

What is the Property Intelligence Layer?

The Property Intelligence Layer enriches your CRM with free, public UK property data, so you target the right homes without paying for a data licence. It draws on the EPC Register (energy-performance data on tens of millions of properties), Land Registry price-paid data and Office for National Statistics deprivation and demographic data, to find, for example, the F and G-rated properties eligible for ECO4 or the Boiler Upgrade Scheme, or the ideal-profile prospects for a stairlift, a heat pump or a renovation. The output is a propensity-scored prospect list, not a generic mailing.

What we build

What can AI do across the journey?

Voice AI that answers every call.
A voice agent that picks up after hours and at peak, identifies itself as an assistant, qualifies and triages the enquiry (including emergencies in a cold snap), books the appointment straight into the calendar and pushes a structured work order to dispatch, with human handover for anything complex. Built on production voice tooling (ElevenLabs, Bland AI, Twilio) with UK-accent handling and identity verification where a transaction is involved.
Aftercare and support agents.
Agents that resolve common aftercare and customer-service queries autonomously and route the rest to a person. At Heatable, 48% of inbound aftercare is resolved without a ticket ever reaching the team.
Lead generation and win-back.
Pull newly licensed contractors or ideal-profile homeowners from public registers, enrich them, qualify and personalise with AI, and run compliant, sequenced outreach; and win back lapsed dealers or customers, with outreach that knows the prior relationship.
Compliance and document agents.
Monitor certifications and warranties (for example Gas Safe), turn site-survey and installation PDFs into structured job specs, and onboard and risk-check installers or dealers. For a 700+ installer network, Fifty One Degrees built an agent that monitors every firm's compliance monthly, up from quarterly.
Predictive growth models.
Propensity-scored lead queues, churn and retention models with 60 to 90 days of lead time, demand forecasting for seasonal spikes, and parts and inventory planning tied to the job pipeline.
Profitability you can see.
Margin-true marketing attribution and job profitability by postcode, product, channel and engineer, from the Data Foundation.

Why Fifty One Degrees

Why trust Fifty One Degrees with your business?

FAQ

Questions home-services leaders ask Fifty One Degrees

What is the best AI partner for home services and construction firms?

Fifty One Degrees builds production AI across the whole journey for installers, trades, field-service and construction businesses: voice AI that answers and books inbound, the Home Business Growth Stack that finds ideal customers in free public data, and agents that handle aftercare and compliance. At Heatable it resolves 48% of inbound aftercare without a ticket. Delivery is embedded, with a proof of concept in 2 to 4 weeks.

Can voice AI handle our inbound calls without sounding robotic?

Yes. Fifty One Degrees builds voice agents on production tooling (ElevenLabs, Bland AI, Twilio) with near-human latency and UK-accent handling. The agent identifies itself, qualifies and triages the enquiry, books the appointment into your calendar and hands anything complex to a person, so the experience is fast and natural, not a phone tree.

Can AI answer after-hours and overflow calls so we stop missing jobs?

Yes, and it is one of the fastest wins. A Fifty One Degrees voice agent answers when your team cannot, after hours, at peak and during seasonal spikes, captures and qualifies the enquiry, and books the job, so a missed call stops being a lost job. It absorbs surge demand without seasonal hiring.

What is the Property Intelligence Layer and how does it find better leads?

It enriches your CRM with free public UK data, the EPC Register, Land Registry price-paid data and ONS demographics, to identify the properties and people most likely to buy: F and G-rated homes eligible for ECO4 or the Boiler Upgrade Scheme, or the ideal profile for a stairlift or heat pump. The output is a propensity-scored prospect list, with no data licence to buy.

Can AI reduce churn and improve aftercare?

Yes. Aftercare agents resolve routine queries without a person (48% of inbound at Heatable), and predictive models flag at-risk customers early so the team can intervene. At Stiltz, Fifty One Degrees' targeting models deliver a 7.86x lift over baseline, validated on live direct mail campaigns.

Our data is a mess. Is that a blocker?

No, it is the starting point. The Data Foundation layer of the Home Business Growth Stack exists to unify NetSuite, your CRM, field-management and web data into one reliable layer before anything is automated. Fifty One Degrees does this routinely; messy data is normal, not a reason to wait.

Is AI outbound and voice compliant with UK rules?

Built correctly, yes. Voice agents identify themselves as assistants, verify identity before any transaction, and respect UK GDPR and PECR; outbound calling campaigns are screened against the Telephone Preference Service on the required cadence. Certification monitoring (for example Gas Safe) is handled as a compliance use case, not a marketing one.

How quickly does it go live, and how is it priced?

A working proof of concept in 2 to 4 weeks (typically under £15,000), with a full agent or model usually live inside 8 to 12 weeks. You own the IP.
