Plumbing & Heating Engineers


Accountants for plumbing & heating engineers and installation businesses
Supporting plumbing and heating engineers across the South West, from independent tradespeople to growing installation and project-based businesses, with structured accounting, tax and advisory.
Helping you stay in control, improve profitability and plan ahead.
Understanding Your Business
Running a plumbing and heating business involves a wide range of work.
You may be carrying out reactive callouts, completing installations and larger projects, managing ongoing maintenance work, and coordinating labour, materials and suppliers.
Many businesses evolve over time, moving from smaller jobs into larger installations and project-based work.
This brings higher job values, longer project timelines, more complex cost structures, and greater financial risk if pricing and cost control are not right.
At this stage, basic accounting is no longer enough.
Our Approach
We provide a structured approach to accounting, tax and advisory, designed specifically for trades businesses like yours.
This includes:
- keeping your records up to date and usable
- ensuring compliance is handled properly (including CIS where applicable)
- helping you understand your financial position
- supporting better pricing and job decisions
- providing forward-looking input as your business grows
So instead of reacting after the year-end, you can:
- understand your position during the year
- make better decisions
- build a more stable and profitable business
Understanding Profitability on Installations
For installation-led plumbing and heating businesses, profitability is not always clear.
We often see:
- jobs priced without full visibility of labour and material costs
- margins reduced during the course of the project
- difficulty tracking actual profitability per job
We help you:
- understand true job profitability
- improve how work is priced
- identify where margins are being lost
So that larger projects contribute properly to your overall profitability.
A Practical System for Managing Cash Flow
Cash flow in plumbing and heating businesses can vary significantly depending on the type of work you do.
We help you implement a structured system for managing money, including our Profit First approach, so that:
- profit is built into your business from the start
- cash is allocated properly
- financial pressure is reduced
This provides a simple and practical framework for managing your finances.
Up-to-Date Numbers You Can Use
Many plumbing and heating businesses only see their numbers after the year-end or when a VAT return is due.
At that point, it is often too late to act.
We maintain your records regularly, monthly, weekly or more frequently depending on your business.
This allows you to:
- understand your current position
- track income across different types of work
- monitor costs and margins
- make decisions based on real-time information
CIS - Where Applicable
Some plumbing and heating businesses operate under the Construction Industry Scheme (CIS), particularly where working on larger projects or subcontracting.
We support:
- subcontractors needing correct deductions and tax treatment
- contractors managing subcontractor reporting and compliance
- businesses operating in both roles
Ensuring everything is handled properly and aligned with your wider tax position.
As Your Business Grows
As your plumbing and heating business grows, things become more complex.
You may begin to:
- take on larger installation projects
- employ staff or subcontractors
- manage multiple jobs at once
- invest in vehicles, equipment and systems
At this stage, you need more than compliance.
You need:
- clear financial visibility
- better control over cash flow
- structured decision-making
We support you through this transition, helping you move from running jobs to running a business.
Supporting Better Decisions
We help you make better decisions around:
- pricing work
- taking on larger projects
- managing growth
- improving margins
- investing in your business
Giving you confidence in how your business is run, not just what gets filed.
