Structured Maintenance Support for Property Portfolios
Managing residential properties requires dependable contractors who understand urgency, compliance and communication.

We Understand What You're Dealing With
When something goes wrong like a boiler failure in January, or an electrical fault flagged on an inspection, you need a contractor who picks up the phone, turns up when they say they will, and sends the paperwork without being asked. That's what hae.works provides.
We've been supporting property portfolios across London, Surrey, Hampshire and Sussex since 1996. We built our service around making your job easier, not harder.
What We Provide
Three service areas designed to support your business.
Reactive Maintenance
When something breaks, you need it fixed. Our engineers respond promptly, provide clear updates throughout the job, and aim for same-day attendance wherever possible. You'll know what's happening, what it costs, and when it's resolved.
- Emergency boiler and heating repairs
- Electrical fault finding and repair
- Air conditioning breakdowns
- Clear updates to you and your tenants at every stage
- Same-day response where possible
Planned Maintenance
Stay ahead of compliance deadlines and reduce emergency call-outs with a structured maintenance programme. We'll schedule annual inspections, coordinate tenant access and deliver certificates digitally — on time, every time.
- Annual Gas Safety Certificates (CP12)
- Electrical Installation Condition Reports (EICR)
- Boiler servicing programmes
- Air conditioning servicing and pre-season checks
- Tenant access coordination
- Digital certificate delivery
Installations & Upgrades
Whether it's a single boiler replacement or a programme of electrical upgrades across your portfolio, we deliver consistent quality with full project management and documentation.
- Boiler replacements (Worcester & Vaillant approved)
- Consumer unit (fuse board) upgrades
- Air conditioning installation
- Full and partial rewires
- Lighting and electrical upgrades
- Specification and quoting for portfolio-wide programmes
"We have worked with London and Surrey Gas Services (Lasgas) for many years (15+ years), and we find that they are very efficient, competent and reliable. Over the years we have developed a healthy working relationship and get along very well with the friendly office personnel as well as the engineers. Using Lasgas has made our daily operations so much easier. Highly recommend!"
Whether you have 10 or 300+ properties, we've built hae.works to handle your challenges:
01. Established & Stable
We've been trading since 1996 with the same standards and same commitment. You're not working with a contractor who appeared last year and might not be here next year.
02. Multi-Trade
Heating, air conditioning and electrical under one contractor. That means one relationship, coordinated scheduling, and consistent conduct across every property in your portfolio.
03. Professional with Tenants
Our engineers represent your business when they're in a tenant's home. They're punctual, presentable, courteous and respectful of the property. That reflects well on you.
04. Clear Documentation
Digital certificates, itemised invoices and consolidated reporting as standard. No chasing paperwork. No ambiguity. Everything you need for your records and your peace of mind.
05. Direct Point of Contact
You'll deal with a named contact at hae.works, not a call centre, and not an answering service. When you call, someone who knows you and your portfolio picks up.
